Subject: [PATCH 0001/1429] net: implement emergency route cache rebulds when
 gc_elasticity is exceeded

This is a patch to provide on demand route cache rebuilding.  Currently, our
route cache is rebulid periodically regardless of need.  This introduced
unneeded periodic latency.  This patch offers a better approach.  Using code
provided by Eric Dumazet, we compute the standard deviation of the average hash
bucket chain length while running rt_check_expire.  Should any given chain
length grow to larger that average plus 4 standard deviations, we trigger an
emergency hash table rebuild for that net namespace.  This allows for the common
case in which chains are well behaved and do not grow unevenly to not incur any
latency at all, while those systems (which may be being maliciously attacked),
only rebuild when the attack is detected.  This patch take 2 other factors into
account:
1) chains with multiple entries that differ by attributes that do not affect the
hash value are only counted once, so as not to unduly bias system to rebuilding
if features like QOS are heavily used
2) if rebuilding crosses a certain threshold (which is adjustable via the added
sysctl in this patch), route caching is disabled entirely for that net
namespace, since constant rebuilding is less efficient that no caching at all

Tested successfully by me.

Subject: [PATCH 0004/1429] net: convert print_mac to %pM

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

From: Johannes Berg <johannes@sipsolutions.net>

Subject: [PATCH 0005/1429] net: convert more to %pM

A number of places still use %02x:...:%02x because it's
in debug statements or for no real reason. Make a few
of them use %pM.

Subject: [PATCH 0006/1429] netns: Coexist with the sysfs limitations v2

To make testing of the network namespace simpler allow
the network namespace code and the sysfs code to be
compiled and run at the same time.  To do this only
virtual devices are allowed in the additional network
namespaces and those virtual devices are not placed
in the kobject tree.

Since virtual devices don't actually do anything interesting
hardware wise that needs device management there should
be no loss in keeping them out of the kobject tree and
by implication sysfs.  The gain in ease of testing
and code coverage should be significant.

Changelog:

v2: As pointed out by Benjamin Thery it only makes sense to call
    device_rename in the initial network namespace for now.

Subject: [PATCH 0011/1429] printk: add %p6 format specifier for IPv6 addresses

Takes a pointer to a IPv6 address and formats it in the usual
colon-separated hex format:
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

Each 16 bit word is printed in network-endian byteorder.

%#p6 is also supported and will omit the colons.

%p6 is a replacement for NIP6_FMT and NIP6()
%#p6 is a replacement for NIP6_SEQFMT and NIP6()

Note that NIP6() took a struct in6_addr whereas this takes a pointer
to a struct in6_addr.

Subject: [PATCH 0013/1429] misc: replace NIP6_FMT with %p6 format specifier

The iscsi_ibft.c changes are almost certainly a bugfix as the
pointer 'ip' is a u8 *, so they never print the last 8 bytes
of the IPv6 address, and the eight bytes they do print have
a zero byte with them in each 16-bit word.

Other than that, this should cause no difference in functionality.

Subject: [PATCH 0017/1429] veth: Remove useless veth field

The veth private structure contains a netdev pointer refering to its peer.
This field is never used and it is pointless because if we can access,
the veth_priv, that means we already have the netdev which is stored
in veth_priv->dev.

Subject: [PATCH 0018/1429] veth: remove unused list

The veth network device is stored in a list in the netdev private.
AFAICS, this list is never used so I removed this list from the code.

Subject: [PATCH 0019/1429] vlan: propogate ethtool speed values

This enables more ethtool information. The speed and settings of the
underlying device are propagated up. This makes services like SNMP that
use ethtool to get speed setting, work when managing a vlan, without adding
silly heurtistics into SNMP daemon.

For the driver info, just use existing driver strings.

Subject: [PATCH 0025/1429] udp: introduce struct udp_table and multiple
 spinlocks

UDP sockets are hashed in a 128 slots hash table.

This hash table is protected by *one* rwlock.

This rwlock is readlocked each time an incoming UDP message is handled.

This rwlock is writelocked each time a socket must be inserted in
hash table (bind time), or deleted from this table (close time)

This is not scalable on SMP machines :

1) Even in read mode, lock() and unlock() are atomic operations and
 must dirty a contended cache line, shared by all cpus.

2) A writer might be starved if many readers are 'in flight'. This can
 happen on a machine with some NIC receiving many UDP messages. User
 process can be delayed a long time at socket creation/dismantle time.

This patch prepares RCU migration, by introducing 'struct udp_table
and struct udp_hslot', and using one spinlock per chain, to reduce
contention on central rwlock.

Introducing one spinlock per chain reduces latencies, for port
randomization on heavily loaded UDP servers. This also speedup
bindings to specific ports.

Some cleanups were done to ease review of following patch
(RCUification of UDP Unicast lookups)

Subject: [PATCH 0026/1429] udp: RCU handling for Unicast packets.

Goals are :

1) Optimizing handling of incoming Unicast UDP frames, so that no memory
 writes should happen in the fast path.

 Note: Multicasts and broadcasts still will need to take a lock,
 because doing a full lockless lookup in this case is difficult.

2) No expensive operations in the socket bind/unhash phases :
  - No expensive synchronize_rcu() calls.

  - No added rcu_head in socket structure, increasing memory needs,
  but more important, forcing us to use call_rcu() calls,
  that have the bad property of making sockets structure cold.
  (rcu grace period between socket freeing and its potential reuse
   make this socket being cold in CPU cache).
  David did a previous patch using call_rcu() and noticed a 20%
  impact on TCP connection rates.
  Quoting Cristopher Lameter :
   "Right. That results in cacheline cooldown. You'd want to recycle
    the object as they are cache hot on a per cpu basis. That is screwed
    up by the delayed regular rcu processing. We have seen multiple
    regressions due to cacheline cooldown.
    The only choice in cacheline hot sensitive areas is to deal with the
    complexity that comes with SLAB_DESTROY_BY_RCU or give up on RCU."

  - Because udp sockets are allocated from dedicated kmem_cache,
  use of SLAB_DESTROY_BY_RCU can help here.

Theory of operation :
---------------------

As the lookup is lockfree (using rcu_read_lock()/rcu_read_unlock()),
special attention must be taken by readers and writers.

Use of SLAB_DESTROY_BY_RCU is tricky too, because a socket can be freed,
reused, inserted in a different chain or in worst case in the same chain
while readers could do lookups in the same time.

In order to avoid loops, a reader must check each socket found in a chain
really belongs to the chain the reader was traversing. If it finds a
mismatch, lookup must start again at the begining. This *restart* loop
is the reason we had to use rdlock for the multicast case, because
we dont want to send same message several times to the same socket.

We use RCU only for fast path.
Thus, /proc/net/udp still takes spinlocks.

Subject: [PATCH 0027/1429] udp: calculate udp_mem based on low memory instead
 of all memory

This patch mimics commit 57413ebc4e0f1e471a3b4db4aff9a85c083d090e
(tcp: calculate tcp_mem based on low memory instead of all memory)

The udp_mem array which contains limits on the total amount of memory
used by UDP sockets is calculated based on nr_all_pages.  On a 32 bits
x86 system, we should base this on the number of lowmem pages.

Subject: [PATCH 0029/1429] udp: introduce sk_for_each_rcu_safenext()

Corey Minyard found a race added in commit 271b72c7fa82c2c7a795bc16896149933110672d
(udp: RCU handling for Unicast packets.)

 "If the socket is moved from one list to another list in-between the
 time the hash is calculated and the next field is accessed, and the
 socket has moved to the end of the new list, the traversal will not
 complete properly on the list it should have, since the socket will
 be on the end of the new list and there's not a way to tell it's on a
 new list and restart the list traversal.  I think that this can be
 solved by pre-fetching the "next" field (with proper barriers) before
 checking the hash."

This patch corrects this problem, introducing a new
sk_for_each_rcu_safenext() macro.

For use in printing IPv4, or IPv6 addresses in the usual way:

%i4 and %I4 are currently equivalent and print the address in
dot-separated decimal x.x.x.x

%I6 prints 16-bit network order hex with colon separators:
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

%i6 omits the colons.

Subject: [PATCH 0037/1429] skge: adapt skge to use reworked PCI PM

Adapt the skge driver to the reworked PCI PM

* Use device_set_wakeup_enable() and friends as needed
* Remove an open-coded reference to the standard PCI PM registers
* Use pci_prepare_to_sleep() and pci_back_from_sleep() in the
  ->suspend() and ->resume() callbacks
* Use the observation that it is sufficient to call pci_enable_wake()
  once, unless it fails

Tested on Asus L5D (Yukon-Lite rev 7).

-				Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's
-single-chip fast Ethernet controller for PCI, as used on the Intel
-EtherExpress Pro 100 adapter.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board.  The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line.  While it's
-possible to share PCI interrupt lines, it negatively impacts performance and
-only recent kernels support it.
-
-III. Driver operation
-
-IIIA. General
-The Speedo3 is very similar to other Intel network chips, that is to say
-"apparently designed on a different planet".  This chips retains the complex
-Rx and Tx descriptors and multiple buffers pointers as previous chips, but
-also has simplified Tx and Rx buffer modes.  This driver uses the "flexible"
-Tx mode, but in a simplified lower-overhead manner: it associates only a
-single buffer descriptor with each frame descriptor.
-
-Despite the extra space overhead in each receive skbuff, the driver must use
-the simplified Rx buffer mode to assure that only a single data buffer is
-associated with each RxFD. The driver implements this by reserving space
-for the Rx descriptor at the head of each Rx skbuff.
-
-The Speedo-3 has receive and command unit base addresses that are added to
-almost all descriptor pointers.  The driver sets these to zero, so that all
-pointer fields are absolute addresses.
-
-The System Control Block (SCB) of some previous Intel chips exists on the
-chip in both PCI I/O and memory space.  This driver uses the I/O space
-registers, but might switch to memory mapped mode to better support non-x86
-processors.
-
-IIIB. Transmit structure
-
-The driver must use the complex Tx command+descriptor mode in order to
-have a indirect pointer to the skbuff data section.  Each Tx command block
-(TxCB) is associated with two immediately appended Tx Buffer Descriptor
-(TxBD).  A fixed ring of these TxCB+TxBD pairs are kept as part of the
-speedo_private data structure for each adapter instance.
-
-The newer i82558 explicitly supports this structure, and can read the two
-TxBDs in the same PCI burst as the TxCB.
-
-This ring structure is used for all normal transmit packets, but the
-transmit packet descriptors aren't long enough for most non-Tx commands such
-as CmdConfigure.  This is complicated by the possibility that the chip has
-already loaded the link address in the previous descriptor.  So for these
-commands we convert the next free descriptor on the ring to a NoOp, and point
-that descriptor's link to the complex command.
-
-An additional complexity of these non-transmit commands are that they may be
-added asynchronous to the normal transmit queue, so we disable interrupts
-whenever the Tx descriptor ring is manipulated.
-
-A notable aspect of these special configure commands is that they do
-work with the normal Tx ring entry scavenge method.  The Tx ring scavenge
-is done at interrupt time using the 'dirty_tx' index, and checking for the
-command-complete bit.  While the setup frames may have the NoOp command on the
-Tx ring marked as complete, but not have completed the setup command, this
-is not a problem.  The tx_ring entry can be still safely reused, as the
-tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.
-
-Commands may have bits set e.g. CmdSuspend in the command word to either
-suspend or stop the transmit/command unit.  This driver always flags the last
-command with CmdSuspend, erases the CmdSuspend in the previous command, and
-then issues a CU_RESUME.
-Note: Watch out for the potential race condition here: imagine
-	erasing the previous suspend
-		the chip processes the previous command
-		the chip processes the final command, and suspends
-	doing the CU_RESUME
-		the chip processes the next-yet-valid post-final-command.
-So blindly sending a CU_RESUME is only safe if we do it immediately after
-after erasing the previous CmdSuspend, without the possibility of an
-intervening delay.  Thus the resume command is always within the
-interrupts-disabled region.  This is a timing dependence, but handling this
-condition in a timing-independent way would considerably complicate the code.
-
-Note: In previous generation Intel chips, restarting the command unit was a
-notoriously slow process.  This is presumably no longer true.
-
-IIIC. Receive structure
-
-Because of the bus-master support on the Speedo3 this driver uses the new
-SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.
-This scheme allocates full-sized skbuffs as receive buffers.  The value
-SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to
-trade-off the memory wasted by passing the full-sized skbuff to the queue
-layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-For small frames the copying cost is negligible (esp. considering that we
-are pre-loading the cache with immediately useful header information), so we
-allocate a new, minimally-sized skbuff.  For large frames the copying cost
-is non-trivial, and the larger copy might flush the cache of useful data, so
-we pass up the skbuff the packet was received into.
-
-IV. Notes
-
-Thanks to Steve Williams of Intel for arranging the non-disclosure agreement
-that stated that I could disclose the information.  But I still resent
-having to sign an Intel NDA when I'm helping Intel sell their own product!

Use the newly introduced pci_ioremap_bar() function in drivers/net.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

Subject: [PATCH 0046/1429] pkt_sched: Add ->peek() methods for fifo, prio and
 SFQ qdiscs.

From: Patrick McHardy <kaber@trash.net>

Just as a demonstration how easy adding a peek operation to the
work-conserving qdiscs actually is. It doesn't need to keep or change
any internal state in many cases thanks to the guarantee that the
packet will either be dequeued or, if another packet arrives, the
upper qdisc will immediately ->peek again to reevaluate the state.

(This is only slightly modified Patrick's patch.)

Subject: [PATCH 0049/1429] pkt_sched: Use qdisc->ops->peek() instead of
 ->dequeue() & ->requeue()

Use qdisc->ops->peek() instead of ->dequeue() & ->requeue() pair.
After this patch the only remaining user of qdisc->ops->requeue() is
netem_enqueue(). Based on ideas of Herbert Xu, Patrick McHardy and
David S. Miller.

Subject: [PATCH 0050/1429] pkt_sched: Add peek emulation for
 non-work-conserving qdiscs.

This patch adds qdisc_peek_dequeued() wrapper to emulate peek method
with qdisc->dequeue() and storing "peeked" skb in qdisc->gso_skb until
dequeuing. This is mainly for compatibility reasons not to break some
strange configs because peeking is expected for non-work-conserving
parent qdiscs to query work-conserving child qdiscs.

This implementation requires using qdisc_dequeue_peeked() wrapper
instead of directly calling qdisc->dequeue() for all qdiscs ever
querried with qdisc->ops->peek() or qdisc_peek_dequeued().

Subject: [PATCH 0052/1429] net: replace NIPQUAD() in net/ipv4/ net/ipv6/

Using NIPQUAD() with NIPQUAD_FMT, %d.%d.%d.%d or %u.%u.%u.%u
can be replaced with %pI4

Subject: [PATCH 0059/1429] mac80211: remove writable debugs mesh parameters

These parameters shouldn't be configurable via debugfs, if they
need to be configurable nl80211 support has to be added, if not
then they don't need to be writable here either.

Warn when ieee80211_hw_config returns an error, it shouldn't
happen; remove a number of printks that would happen in such
a case and one printk that is user-triggerable.

Subject: [PATCH 0063/1429] mac80211: remove max_antenna_gain config

The antenna gain isn't exactly configurable, despite the belief of
some unnamed individual who thinks that the EEPROM might influence
it.

Subject: [PATCH 0064/1429] mac80211: fix short slot handling

This patch makes mac80211 handle short slot requests from the AP
properly. Also warn about uses of IEEE80211_CONF_SHORT_SLOT_TIME
and optimise out the code since it cannot ever be hit anyway.

This patch adds ability to configure initial calibration set. Not all HW
supported by iwlwifi use the same calibration set, XTAL is one example.
Some clean ups are also included in this patch.

Subject: [PATCH 0068/1429] iwlwifi: refactor rxon time command

This patch refactors rxon time command. It removes the usage of union tsf
in favor of u64 value and hopefully makes code more readable.  There are
no functional changes in this patch.

This patch fixes a typo in mac80211_hwsim.c:
use HWSIM_STA_MAGIC in hwsim_check_sta_magic() and hwsim_set_sta_magic()
instead of HWSIM_VIF_MAGIC.

Subject: [PATCH 0070/1429] p54: honour bss_info_changed's short slot time
 settings

This patch was made on behalf of Johannes request.
"mac80211 and IEEE80211_CONF_SHORT_SLOT_TIME"

Of course, bss_info_changed provides some more useful data.
e.g.: basic_rates, dtim_period, beacon_int and maybe even more.
Everything can be hooked up if it's necessary.

Subject: [PATCH 0071/1429] 802.11: clean up/fix HT support

This patch cleans up a number of things:
 * the unusable definition of the HT capabilities/HT information
   information elements
 * variable names that are hard to understand
 * mac80211: move ieee80211_handle_ht to ht.c and remove the unused
             enable_ht parameter
 * mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht
 * mac80211: fix bug with casting the result of ieee80211_bss_get_ie
             to an information element _contents_ rather than the
             whole element, add size checking (another out-of-bounds
             access bug fixed!)
 * mac80211: remove some unused return values in favour of BUG_ON
             checking
 * a few minor other things

Subject: [PATCH 0073/1429] mac80211: introduce hw config change flags

This makes mac80211 notify the driver which configuration
actually changed, e.g. channel etc.

No driver changes, this is just plumbing, driver authors are
expected to act on this if they want to.

Also remove the HW CONFIG debug printk, it's incorrect, often
we configure something else.

Subject: [PATCH 0074/1429] rfkill: use killable locks instead of interruptible

Apparently, many applications don't expect to get EAGAIN from fd read/write
operations, since POSIX doesn't mandate it.

Use mutex_lock_killable instead of mutex_lock_interruptible, which won't
cause issues.

Subject: [PATCH 0076/1429] rfkill: add master_switch_mode and EPO lock to
 rfkill and rfkill-input

Add of software-based sanity to rfkill and rfkill-input so that it can
reproduce what hardware-based EPO switches do, blocking all transmitters
and locking down any further attempts to unblock them until the switch is
deactivated.

rfkill-input is responsible for issuing the EPO control requests, like
before.

While an rfkill EPO is active, all transmitters are locked to one of the
BLOCKED states and all attempts to change that through the rfkill API
(userspace and kernel) will be either ignored or return -EPERM errors.

The lock will be released upon receipt of EV_SW SW_RFKILL_ALL ON by
rfkill-input, or should modular rfkill-input be unloaded.

This makes rfkill and rfkill-input extend the operation of an existing
wireless master kill switch to all wireless devices in the system, even
those that are not under hardware or firmware control.

Since the above is the expected operational behavior for the master rfkill
switch, the EPO lock functionality is not optional.

Also, extend rfkill-input to allow for three different behaviors when it
receives an EV_SW SW_RFKILL_ALL ON input event.  The user can set which
behavior he wants through the master_switch_mode parameter:

master_switch_mode = 0: EV_SW SW_RFKILL_ALL ON just unlocks rfkill
controller state changes (so that the rfkill userspace and kernel APIs can
now be used to change rfkill controller states again), but doesn't change
any of their states (so they will all remain blocked).  This is the safest
mode of operation, as it requires explicit operator action to re-enable a
transmitter.

master_switch_mode = 1: EV_SW SW_RFKILL_ALL ON causes rfkill-input to
attempt to restore the system to the state before the last EV_SW
SW_RFKILL_ALL OFF event, or to the default global states if no EV_SW
SW_RFKILL_ALL OFF ever happened.   This is the recommended mode of
operation for laptops.

master_switch_mode = 2: tries to unblock all rfkill controllers (i.e.
enable all transmitters) when an EV_SW SW_RFKILL_ALL ON event is received.
This is the default mode of operation, as it mimics the previous behavior
of rfkill-input.

In order to implement these features in a clean way, the entire event
handling of rfkill-input was refactored into a single worker function.

Protection against input event DoS (repeatedly firing rfkill events for
rfkill-input to process) was removed during the code refactoring.  It will
be added back in a future patch.

Note that with these changes, rfkill-input doesn't need to explicitly
handle any radio types for which KEY_<radio type> or SW_<radio type> events
do not exist yet.

Code to handle EV_SW SW_{WLAN,WWAN,BLUETOOTH,WIMAX,...} was added as it
might be needed in the future (and its implementation is not that obvious),
but is currently #ifdef'd out to avoid wasting resources.

Subject: [PATCH 0077/1429] rfkill: honour EPO state when resuming a rfkill
 controller

rfkill_resume() would always restore the rfkill controller state to its
pre-suspend state.

Now that we know when we are under EPO, kick the rfkill controller to
SOFT_BLOCKED state instead of to its pre-suspend state when it is resumed
while EPO mode is active.

Subject: [PATCH 0078/1429] rfkill: rate-limit rfkill-input workqueue usage
 (v3)

Limit the number of "expensive" rfkill workqueue operations per second, in
order to not hog system resources too much when faced with a rogue source
of rfkill input events.

The old rfkill-input code (before it was refactored) had such a limit in
place.  It used to drop new events that were past the rate limit.  This
behaviour was not implemented as an anti-DoS measure, but rather as an
attempt to work around deficiencies in input device drivers which would
issue multiple KEY_FOO events too soon for a given key FOO (i.e. ones that
do not implement mechanical debouncing properly).

However, we can't really expect such issues to be worked around by every
input handler out there, and also by every userspace client of input
devices.  It is the input device driver's responsability to do debouncing
instead of spamming the input layer with bogus events.

The new limiter code is focused only on anti-DoS behaviour, and tries to
not lose events (instead, it coalesces them when possible).

The transmitters are updated once every 200ms, maximum.  Care is taken not
to delay a request to _enter_ rfkill transmitter Emergency Power Off (EPO)
mode.

If mistriggered (e.g. by a jiffies counter wrap), the code delays processing
*once* by 200ms.

The patch entitled "[PATCH] p54: Fix sparse warnings" added the __le16
variable rx_mtu to struct bootrec, but it could equally well be placed
in the struct bootrec_desc, which overlays the 'data' section of bootrec.

Subject: [PATCH 0080/1429] mac80211: provide sequence numbers

I've come to think that not providing sequence numbers for
the normal STA mode case was a mistake, at least two drivers
now had to implement code they wouldn't otherwise need, and
I believe at76_usb and adm8211 might be broken.

This patch makes mac80211 assign a sequence number to all
those frames that need one except beacons. That means that
if a driver only implements modes that do not do beaconing
it need not worry about the sequence number.

From: Johannes Berg <johannes@sipsolutions.net>
Date: Tue, 14 Oct 2008 19:17:54 +0200
Subject: [PATCH 0083/1429] mac80211: make retry limits part of hw config

Instead of having a separate callback, use the HW config callback
with a new flag to change retry limits.

From bda3933a8aceedd03e0dd410844bd310033ca756 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Sat, 11 Oct 2008 01:51:51 +0200
Subject: [PATCH 0084/1429] mac80211: move bss_conf into vif

Move bss_conf into the vif struct so that drivers can
access it during ->tx without having to store it in
the private data or similar. No driver updates because
this is only for when they want to start using it.

Subject: [PATCH 0085/1429] mac80211: rewrite HT handling

The HT handling has the following deficiencies, which I've
(partially) fixed:
 * it always uses the AP info even if there is no AP,
   hence has no chance of working as an AP
 * it pretends to be HW config, but really is per-BSS
 * channel sanity checking is left to the drivers
 * it generally lets the driver control too much

HT enabling is still wrong with this patch if you have more than
one virtual STA mode interface, but that never happens currently.
Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be
wrong, see the comment in ieee80211_enable_ht().

Additionally, this fixes a number of bugs:
 * mac80211: ieee80211_set_disassoc doesn't notify the driver any
             more since the refactoring
 * iwl-agn-rs: always uses the HT capabilities from the wrong stuff
               mac80211 gives it rather than the actual peer STA
 * ath9k: a number of bugs resulting from the broken HT API

I'm not entirely happy with putting the HT capabilities into
struct ieee80211_sta as restricted to our own HT TX capabilities,
but I see no cleaner solution for now.

Subject: [PATCH 0087/1429] Ath5k: add AP mode

Add support for AP mode. This involves:
- enablement in ath5k_beacon_config -- initialize beacon timer
- add AP to the supported modes in ath5k_add_interface
- handle beacon change even for AP in ath5k_config_interface
- remove useless test for IBSS in ath5k_beacon_update

Note that it doesn't enable the AP mode for the driver. It must
be enabled by NL80211_IFTYPE_AP bit added to interface_modes.

v2:
Fixed opmode constant (IEEE80211_ to NL80211_)

Subject: [PATCH 0088/1429] rtl8187: adapt for deprecated
 IEEE80211_CONF_SHORT_SLOT_TIME flag

This updates 8187L handling for short slot after "mac80211: fix short
slot handling". For 8187B, there was no handling done for short slot
timing so nothing done, support for it will come in a following patch.

Subject: [PATCH 0089/1429] rtl8187: add short slot handling for 8187B

This change adds short slot handling for 8187B variant of rtl8187 chips.
Some things to note about changes done:
* Values used are chosen to met 802.11-2007 spec. This raised a question
  about SIFS value used with 8187L: 0x22 (34) doesn't match any spec
  value. For now just don't change 8187L, but is something to be
  looked at.
* On 8187B, the location of EIFS register is at the same place as BRSR+1
  of struct rtl818x_csr. Unfortunately there is no clean way to
  accomodate 8187B differences currently, just use address of BRSR+1 and
  comment about it. The same thing happens for Ack timeout register,
  that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack
  timeout values are in units of 4us. All these registers information
  was gathered from references being the vendor gpl driver and 8180
  datasheet, unfortunately there is no information about this on 8187B
  datasheet. Also the ack timeout value was inspired by the same
  calculation as done on rt2x00.

This patch fixes mesh point operation (thanks to YanBo for pointing
out the problem): make mesh point interfaces start beaconing when
they come up and configure the RX filter in mesh mode so that mesh
beacons and action frames are received.  Add mesh point to the check
in ath5k_add_interface.  Tested with multiple AR5211 cards.

Subject: [PATCH 0094/1429] airo: Kill directly reference of netdev->priv

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

In this driver, I don't simply use netdev_priv() to replace netdev->priv.

The reason is:
Pointer netdev->priv was changed in this driver, but it shouldn't.
Because the memory was allocated when alloc_netdev() and netdev->priv
should always point to that memory.

So I use netdev->ml_priv to replace netdev->priv.
After replacing, both ai and ai->wifidev->ml_priv point to the same memory.

Subject: [PATCH 0096/1429] mac80211/drivers: rewrite the rate control API

So after the previous changes we were still unhappy with how
convoluted the API is and decided to make things simpler for
everybody. This completely changes the rate control API, now
taking into account 802.11n with MCS rates and more control,
most drivers don't support that though.

Subject: [PATCH 0099/1429] make ieee80211 invisible

This makes CONFIG_IEEE80211 invisible. The drivers that require it
(ipw2100, ipw2200, hostap) select it, and everybody else really
shouldn't even think about using it. Also, since there really is
no point in compiling anything without crypto support these days,
remove the crypto options and just enable them, leaving only the
debugging option which only shows up when a driver is select that
requires it. This makes it hard to enable, but most people wouldn't
want to anyway.

Subject: [PATCH 0103/1429] iwlwifi: add iwl_cmd_queue_free for readability

This patch adds iwl_cmd_queue_free function and
separate cmd queue freeing from regular tx queue freeing.
This improves readability and adds one more step in
restructuring  of cmd queue handling

Subject: [PATCH 0105/1429] iwlwifi: fix TX cmd dma unmapping

This patch:
1. fixes command DMA unmapping, this might be visible only
	on platforms where DMA unmapping is no noop such as PPC64 (not tested)
2. attaches correctly high memory part of the host command buffer
3. changes structure of TFD TB
	instead of describing transmit buffer (TB) tuple it describes single
	TB and makes code more readable on price of one unaligned access
4. eliminates using of IWL_GET/SET_BITs for TFD handling
5. renames TFD structures to mach the HW spec
6. reduces iwl_tx_info size by reserving first TB to the host command

This patch should not have any visible effect on x86 32

This patch is rework of
iwlwifi: fix DMA code and bugs from

Subject: [PATCH 0109/1429] p54: p54: refactor p54_rx_frame_sent

the long names and the nesting in p54_rx_frame_sent really
became a "line longer than 80 characters" problem.

Subject: [PATCH 0110/1429] p54: fix memory management

We have to be careful if multiple "control frames" are passed in a very short intervals to
the device's firmware. As p54_assign_address always put them into same memory location.
To guarantee that this won't happen anymore, we have to treat control frames like normal
data frames in the devices own memory management.

From 27df605ebe2c106c53957dfdaee5d948f01cfc97 Mon Sep 17 00:00:00 2001
From: "John W. Linville" <linville@tuxdriver.com>
Date: Wed, 22 Oct 2008 16:41:55 -0400
Subject: [PATCH 0112/1429] p54: integrate parts of lmac_longbow.h and other
 parts of stlc45xx

This patch removes most/all? of the "magic" numbers and unknown structure
variables inside the code and replaces them with meaningful prototypes.

(Plus a one line warning fix from Larry Finger <Larry.Finger@lwfinger.net>.)

Subject: [PATCH 0113/1429] nl80211: fix monitor flags

NLA_NESTED attributes cannot be empty, but we want to be able to
specify "no flags" (empty attribute) vs. "no change" (no attribute).
Therefore, remove the NLA_NESTED policy so it can work as an empty
attribute.

I guess I should have used a u32 for these flags instead, but we're
stuck with it now. Haven't noticed earlier because of a bug in iw...

Subject: [PATCH 0114/1429] minstrel: improve performance for non-MRR drivers

This patch enhances minstrel's performance for non-MRR setups,
by preventing it from sampling slower rates with >95% success
probability and by putting at least 1 non-sample frame between
several sample frames.

Subject: [PATCH 0116/1429] mac80211: remove rate_control_clear

"Clearing" the rate control algorithm is pointless, none of
the algorithms actually uses this operation and it's not even
invoked properly for all channel switching. Also, there's no
need to since rate control algorithms work per station.

Subject: [PATCH 0118/1429] mac80211: inform userspace of probe/auth/assoc
 timeout

I noticed that when for some reason [1] the probe or auth times
out, wpa_supplicant doesn't realise this and only tries the next
AP when it runs into its own timeout, which is ten seconds, and
that's quite long. Fix this by making mac80211 notify userspace
that it didn't associate.

[1] my wrt350n in mixed B/G/HT mode often runs into this, maybe
it's because one of the antennas is broken off and for whatever
reason it decides to use that antenna to transmit the response
frames (auth, probe); I do see beacons fine so it's not totally
broken. Works fine in pure-G mode.

Subject: [PATCH 0119/1429] Add nl80211 commands to get and set o11s mesh
 networking parameters

The two new commands are NL80211_CMD_GET_MESH_PARAMS and
NL80211_CMD_SET_MESH_PARAMS. There is a new attribute enum,
NL80211_ATTR_MESH_PARAMS, which enumerates the various mesh configuration
parameters.

Moved struct mesh_config from mac80211/ieee80211_i.h to net/cfg80211.h.
nl80211_get_mesh_params and nl80211_set_mesh_params unpack the netlink messages
and ask the driver to get or set the configuration.  This is done via two new
function stubs, get_mesh_params and set_mesh_params, in struct cfg80211_ops.

Subject: [PATCH 0120/1429] ath5k: reduce checkpatch.pl errors

A few changes to reduce checkpatch.pl errors in the ath5k driver.  For
the most part, I only fixed cosmetic things, and left the actual 'code
flow' untouched (hopefully)!

Diff is against wireless-testing HEAD.

Subject: [PATCH 0124/1429] wireless: remove cfg80211_reg_mutex

This mutex is wrong, we use cfg80211_drv_mutex (which should
possibly be renamed to just cfg80211_mutex) everywhere except
in one place, fix that and get rid of the extra mutex.

Also get rid of a spurious regulatory_requests list definition.

Subject: [PATCH 0129/1429] mac80211: insert AP sta entry after filling it

We never clearly defined the semantics of the sta_notify callback
and it was originally posted for iwlwifi which still doesn't use
it at all. With the recent HT rework ath9k started relying on it,
but I made a mistake there in that I made ath9k assume the HT
information has already been filled in at sta_notify time. This
isn't a hard thing to do, so do it.

Subject: [PATCH 0131/1429] wireless: remove NETWORK_EMPTY_ESSID flag

It is unnecessary and of questionable value.  Also remove
is_empty_ssid, as it is also unnecessary.

Subject: [PATCH 0134/1429] wireless: avoid some net/ieee80211.h vs.
 linux/ieee80211.h conflicts

There is quite a lot of overlap in definitions between these headers...

Subject: [PATCH 0136/1429] mac80211: make use of regulatory tx power settings
 on change of tx power

We do not know what max power to allow until a device is targeting
a channel, therefore only allow changing tx power if a channel is defined.
Also make use of the channel's max power setting as defined by
regulatory rules before allowing the user to use the requested power
setting. If the user asked us to figure it out we use the max allowed
by regulatory.

Subject: [PATCH 0137/1429] ath9k: remove pointless sc_txintrperiod and
 spin_lock_bh on tx prepare

sc_txintrperiod is currently set to 0 and never updated. We won't
be using this, if anything we will consider using TX interrupt
mitigation but that is different and not yet tested. So remove
sc_txintrperiod and the pointless spin_lock_bh() on tx prepare.

We were also changing tx power even when we were not asked to,
this enforces the change only when we are asked nicely. When
not asked we simply try to use the max power, we don't tx power
at all for rate control.

Eliminate the vif.type check in ieee80211_rx_h_action.  This check is
unnecessary (these action frames can be handled by all interface types) and
currently prevents, for example, AP interfaces from handling BACK action frames
such as ADDBA and DELBA requests.

Subject: [PATCH 0144/1429] mac80211: Re-enable aggregation

Wireless HW without any dedicated queues for aggregation
do not need the ampdu_queues mechanism present right now
in mac80211. Since mac80211 is still incomplete wrt TX MQ
changes, do not allow aggregation sessions for drivers that
set ampdu_queues.

This is only an interim hack until Intel fixes the requeue issue.

Subject: [PATCH 0145/1429] iwlwifi: refactor TX response flow

This patch utilize 5000 new TX response command
which contains all necessary information and avoids
back referencing to the original TX frame.
It also change handling of software queue tracking
4965 flow is aligned with changes as much as possible.

From: Tomas Winkler <tomas.winkler@intel.com>
Date: Thu, 23 Oct 2008 23:48:52 -0700
Subject: [PATCH 0148/1429] iwlwifi: calibration command namespace renaming

Since calibration framework is not HW specific remove 5000 and 4965 prefix
This patch doesn't provide any functional changes only code renaming
and movement

Subject: [PATCH 0149/1429] iwlwifi: convert correctly rate_n_flags to PLCP
 index for mimo3 packets

The driver does not properly convert rate_n_flags to PLCP index for mimo3
packets. This makes mac80211 drop the packets

Subject: [PATCH 0150/1429] iwlwifi: clear scanning bits upon failure

In iwl_bg_request_scan function, if we could not send a
scan command it will go to done.
In done it does the right thing to call mac80211 with
scan complete, but the problem is STATUS_SCAN_HW is still
set causing any future scan to fail. Fix by clearing the scanning status
bits if scan fails.

Subject: [PATCH 0151/1429] iwlwifi: refactor tx byte count table usage

This patch drops unreadable usage of IWL_SET/GET_BITS16 in byte count
tables handling
This patch also cleans a bit the byte count table code and adds
WARN_ON traps on invalid values

This patch is pure cleanup, no functional changes.

Subject: [PATCH 0153/1429] iwl3945: iwl3945_mac_get_tsf() should not return
 zero

The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the
function is not implemented, and this is considered as a valid value by
the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc
mode is inserted/removed quite frequently due to IBSS merging.

This patch fixes :
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1781
and https://bugzilla.redhat.com/show_bug.cgi?id=459401

Subject: [PATCH 0156/1429] wireless: remove struct regdom hinting

The code needs to be split out and cleaned up, so as a
first step remove the capability, to add it back in a
subsequent patch as a separate function. Also remove the
publically facing return value of the function and the
wiphy argument. A number of internal functions go from
being generic helpers to just being used for alpha2
setting.

Subject: [PATCH 0157/1429] wireless: clean up regulatory ignore_request
 function

This function has a few WARNs that may eventually trigger
when an AP sends rogue beacons, those must be removed. Some
of the comments in the function are also inappropriate as
this function is concerned with the global hint, not a per-
wiphy thing (which a multidomain flag on a wiphy would imply).

I'm convinced that we don't need to do anything to implement
multi-domain capability as 802.11-2007 specifies it because
it makes only two things mandatory:
 * starting of BSS/IBSS must have country information
   (this can easily be done with a mac80211 patch)
 * a STA must adopt the country information (we already have
   the framework for this)

But we don't have anything implemented anyway for now.

Subject: [PATCH 0159/1429] ath5k: Update interrupt masking code

*Properly get/set all available ISR/IMR values and review common/uncommon bits
*Better handling of per-txq interrupts (we can now resolve what q is generating
 each interrupt -this will help in debuging wme later)
*Some minor updates from legacy-hal
*Properly handle RXNOFRM and TXNOFRM interrupt masking (even when we don't set
 them on IMR they keep showing up, so we disable them by zeroing AR5K_RXNOFRM
 and AR5K_TXNOFRM registers). This doesn't exist on legacy-hal but i've tested
 it on various cards and it works fine.

Subject: [PATCH 0161/1429] orinoco: cache downloadable firmware image in
 memory for use during resume

If card is using downloadable firmware (like Agere 9.x), firmware has
to be reloaded during resume. It is not possible to use request_firmware
for that, because tasks are still frozen, so request_firmware will
just timeout and fail. So cache firmware image in memory for later
reuse in ->resume method.

Subject: [PATCH 0165/1429] xfrm6: handling fragment

RFC4301 Section 7.1 says:

"7.1.  Tunnel Mode SAs that Carry Initial and Non-Initial Fragments

     All implementations MUST support tunnel mode SAs that are configured
     to pass traffic without regard to port field (or ICMP type/code or
     Mobility Header type) values.  If the SA will carry traffic for
     specified protocols, the selector set for the SA MUST specify the
     port fields (or ICMP type/code or Mobility Header type) as ANY.  An
     SA defined in this fashion will carry all traffic including initial
     and non-initial fragments for the indicated Local/Remote addresses
     and specified Next Layer protocol(s)."

But for IPv6, fragment is treated as a protocol.  This change catches
protocol transported in fragmented packet.  In IPv4, there is no
problem.

Subject: [PATCH 0166/1429] udp: add a missing smp_wmb() in udp_lib_get_port()

Corey Minyard spotted a missing memory barrier in udp_lib_get_port()

We need to make sure a reader cannot read the new 'sk->sk_next' value
and previous value of 'sk->sk_hash'. Or else, an item could be deleted
from a chain, and inserted into another chain. If new chain was empty
before the move, 'next' pointer is NULL, and lockless reader can
not detect it missed following items in original chain.

This patch is temporary, since we expect an upcoming patch
to introduce another way of handling the problem.

Subject: [PATCH 0169/1429] sch_netem: Remove classful functionality

Patrick McHardy noticed that: "a lot of the functionality of netem
requires the inner tfifo anyways and rate-limiting is usually done
on top of netem. So I would suggest so either hard-wire the tfifo
qdisc or at least make the assumption that inner qdiscs are
work-conserving.", and later: "- a lot of other qdiscs still don't
work as inner qdiscs of netem [...]".

So, according to his suggestion, this patch removes classful options
of netem. The main reason of this change is to remove ops->requeue()
method, which is currently used only by netem.

Subject: [PATCH 0170/1429] sch_netem: Replace ->requeue() method with open
 code

After removing netem classful functionality we are sure its inner
qdisc is tfifo, so we can replace qdisc->ops->requeue() method with
open code. After this patch there are no more ops->requeue() users.

The idea of this patch is by Patrick McHardy.

Subject: [PATCH 0174/1429] forcdeth: increase max_interrupt_work

This eliminates the following often-generated warning from my 64 bit
Opteron SMP test stand:

	eth0: too many iterations (6) in nv_nic_irq

According to the web, the problem is that the forcedeth driver has a
too-low value for max_interrupt_work.  Grepping the kernel I see that
forcedeth has the second lowest value of all ethernet drivers (ie, 6).
Most are in the 20-40 range.  So this patch increases this a bit, from 6
to 15 (at 15 forcedeth becomes the driver with third-lowest
max_interrupt_work value).

My test stand, which used to print out the above warnings repetitively
whenever it was under heavy net load, no longer does so.

Subject: [PATCH 0176/1429] bonding: update docs to correctly reflect
 arp_ip_target behavior

This documentation patch hopes to clarify that the '+' was only needed
for Fedora 7 and Red Hat Enterprise Linux 5.0 and 5.1.  After that the
IP addreses could be added as a comma separated list just like the
module option.

Subject: [PATCH 0191/1429] tg3: Use pci_ioremap_bar()

This patch replaces the existing APE register mapping code with a call
to pci_ioremap_bar().  The code that maps the main device register space
did not undergo a similar change because the information derived from
the pci_resource_start() and pci_resource_len() is still used to
populate the (optional) mem_start and mem_end netdevice members.
Replace hardcoded constants where appropriate.

Subject: [PATCH 0192/1429] tg3: Preserve DASH connectivity when WOL enabled

DASH firmware runs on the APE side of the chip, but it requires a few MAC
to be programmed correctly.

When WOL is enabled and management firmware is disabled, incoming
packets are evaluated and discarded at the chip's rule processor.
When management firmware is enabled, the hardware must be informed that
there are agents further up the stack that still use the incoming
frames.  Normally management firmware will configure the MAC correctly
on its own, but there can be cases where the setting could get clobbered
by the driver.  The first hunk of this patch preserves this setting.

The second hunk of this patch wipes out the driver present signature of
the APE memory space.  By doing so, the DASH firmware can assume
driver absent behavior.

Subject: [PATCH 0194/1429] tg3: Reclaim TG3_FLG3_5761_5784_AX_FIXES flag

This patch reclaims the TG3_FLG3_5761_5784_AX_FIXES flag.  It only
used twice in non-fast paths.  This patch also consolidates some other
places where specific 5784 AX chip revisions can be generalized.

Subject: [PATCH 0195/1429] tg3: Do not enable APE on bcm5700

With older versions of the NVRAM format, the driver may mistakenly
determine that APE is enabled.  Make sure this doesn't happen by
restricting the ENABLE_APE check to devices known to have more
recent NVRAM image formats.

Currently, phylib reports appear with a eth%d prefix.  Move the line
after register_netdev() and place it alongside the other informative
messages.  Update nearby informative messages accordingly.

Subject: [PATCH 0197/1429] tg3: Refine power management and WOL code

Commit 12dac0756d357325b107fe6ec24921ec38661839 ("tg3: adapt tg3 to
use reworked PCI PM code") introduced the new PCI PM API to the tg3
driver.  The patch was understandably conservative, so this patch
elaborates on that work.

The patch starts by creating a single point in tg3_set_power_state()
to decide whether or not to enable WOL.  The rest of the code in
tg3_set_power_state() was then pivoted to use the result of this
decision.

The patch then makes sure the device is allowed to wakeup before
reporting whether or not WOL is currently enabled.  The final hunks of
the patch consolidate where the WOL capability and WOL enabled flags
are set to a single location.

Subject: [PATCH 0198/1429] tg3: Allow WOL for phylib controlled Broadcom phys

This patch allows WOL to be enabled for Broadcom phys under phylib
control.  The only exception is the AC131, which has a completely
different register set.

Subject: [PATCH 0199/1429] tg3: Refine phylib support

This patch refines the phylib support in the tg3 driver.  The patch does
the following things :

* Rename tg3_mdio_config() to tg3_mdio_config_5785().  The 5785 will be
  the only device that will use it so the name might as well reflect
  that.
* Fix a memory leak if mdiobus_register() fails.
* Add code to deal with phy device detection failures.
* Add code to correct the supported list of phy features based on the
  MAC <=> PHY interface.

Subject: [PATCH 0205/1429] IPVS: Add IPv6 support to LBLC/LBLCR schedulers

Add IPv6 support to LBLC and LBLCR schedulers. These were the last
schedulers without IPv6 support, but we might want to keep the
supports_ipv6 flag in the case of future schedulers without IPv6
support.

Subject: [PATCH 0208/1429] net: increase receive packet quantum

This patch gets about 1.25% back on tbench regression.

My change to NAPI for multiqueue support changed the time limit on
network receive processing.  Under sustained loads like tbench, this
can cause the receiver to reschedule prematurely.

Subject: [PATCH 0209/1429] bonding, net: Move last_rx update into bonding recv
 logic

	The only user of the net_device->last_rx field is bonding.
This patch adds a conditional update of last_rx to the bonding special
logic in skb_bond_should_drop, causing last_rx to only be updated when
the ARP monitor is running.

	This frees network device drivers from the necessity of
updating last_rx, which can have cache line thrash issues.

Subject: [PATCH 0210/1429] net: '&' redux

I want to compile out proc_* and sysctl_* handlers totally and
stub them to NULL depending on config options, however usage of &
will prevent this, since taking adress of NULL pointer will break
compilation.

So, drop & in front of every ->proc_handler and every ->strategy
handler, it was never needed in fact.

Subject: [PATCH 0212/1429] drivers/net: Kill now superfluous ->last_rx stores.

The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

Subject: [PATCH 0215/1429] netfilter: xt_NFLOG: don't call nf_log_packet in
 NFLOG module.

This patch modifies xt_NFLOG to suppress the call to nf_log_packet()
function. The call of this wrapper in xt_NFLOG was causing NFLOG to
use the first initialized module. Thus, if ipt_ULOG is loaded before
nfnetlink_log all NFLOG rules are treated as plain LOG rules.

* propagate netns from userspace, register table in passed netns
* remporarily register every ebt_table in init_net

P. S.: one needs to add ".netns_ok = 1" to igmp_protocol to test with
ebtables(8) in netns.

* return ebt_table from ebt_register_table(), module code will save it into
  per-netns data for unregistration
* duplicate ebt_table at the very beginning of registration -- it's added into
  list, so one ebt_table wouldn't end up in many lists (and each netns has
  different one)
* introduce underscored tables in individial modules, this is temporary to not
  break bisection.

Subject: [PATCH 0220/1429] netfilter: netns ebtables: more cleanup during
 ebt_unregister_table()

Now that ebt_unregister_table() can be called during netns stop, and module
pinning scheme can't prevent netns stop, do table cleanup by hand.

Subject: [PATCH 0225/1429] netfilter: nf_nat: remove warn_if_extra_mangle

In net/ipv4/netfilter/nf_nat_rule.c, the function warn_if_extra_mangle was added
in commit 5b1158e909ecbe1a052203e0d8df15633f829930 (2006-12-02). I have a DNAT
target in the OUTPUT chain than changes connections with dst 2.0.0.1 to another
address which I'll substitute with 66.102.9.99 below.

On every boot I get the following message:
[  146.252505] NAT: no longer support implicit source local NAT
[  146.252517] NAT: packet src 66.102.9.99 -> dst 2.0.0.1

As far as I can tell from reading the function doing this, it should warn if the
source IP for the route to 66.102.9.99 is different from 2.0.0.1 but that is not
the case. It doesn't make sense to check the DNAT target against the local route
source.

Either the function should be changed to correctly check the route, or it should
be removed entirely as it's been nearly 2 years since it was added.

Subject: [PATCH 0227/1429] dccp: Basic data structure for feature negotiation

This patch prepares for the new and extended feature-negotiation
routines.

The following feature-negotiation data structures are provided:
	* a container for the various (SP or NN) values,
	* symbolic state names to track feature states,
	* an entry struct which holds all current information together,
	* elementary functions to fill in and process these structures.

Entry structs are arranged as FIFO for the following reason: RFC 4340
specifies that if multiple options of the same type are present, they
are processed in the order of their appearance in the packet; which
means that this order needs to be preserved in the local data
structure (the later insertion code also respects this order).

The struct list_head has been chosen for the following reasons: the most
frequent operations are

 * add new entry at tail (when receiving Change or setting socket
   options);
 * delete entry (when Confirm has been received);
 * deep copy of entire list (cloning from listening socket onto
   request socket).

The NN value has been set to 64 bit, which is a currently sufficient
upper limit (Sequence Window feature has 48 bit).

Thanks to Arnaldo, who contributed the streamlined layout of the entry
struct.

Subject: [PATCH 0232/1429] net: sk_free_datagram() should use
 sk_mem_reclaim_partial()

I noticed a contention on udp_memory_allocated on regular UDP applications.

While tcp_memory_allocated is seldom used, it appears each incoming UDP frame
is currently touching udp_memory_allocated when queued, and when received by
application.

One possible solution is to use sk_mem_reclaim_partial() instead of
sk_mem_reclaim(), so that we keep a small reserve (less than one page)
of memory for each UDP socket.

We did something very similar on TCP side in commit
9993e7d313e80bdc005d09c7def91903e0068f07
([TCP]: Do not purge sk_forward_alloc entirely in tcp_delack_timer())

A more complex solution would need to convert prot->memory_allocated to
use a percpu_counter with batches of 64 or 128 pages.

Subject: [PATCH 0233/1429] netns: Delete virtual interfaces during namespace
 cleanup

When physical devices are inside of network namespace and that
network namespace terminates we can not make them go away.  We
have to keep them and moving them to the initial network namespace
is the best we can do.

For virtual devices left in a network namespace that is exiting
we have no need to preserve them and we now have the infrastructure
that allows us to delete them.  So delete virtual devices when we
exit a network namespace.  Keeping the necessary user space clean up
after a network namespace exits much more tractable.

Subject: [PATCH 0234/1429] net: Guaranetee the proper ordering of the loopback
 device.

I was recently hunting a bug that occurred in network namespace
cleanup.  In looking at the code it became apparrent that we have
and will continue to have cases where if we have anything going
on in a network namespace there will be assumptions that the
loopback device is present.   Things like sending igmp unsubscribe
messages when we bring down network devices invokes the routing
code which assumes that at least the loopback driver is present.

Therefore to avoid magic initcall ordering hackery that is hard
to follow and hard to get right insert a call to register the
loopback device directly from net_dev_init().    This guarantes
that the loopback device is the first device registered and
the last network device to go away.

Subject: [PATCH 0235/1429] net: Don't leak packets when a netns is going down

I have been tracking for a while a case where when the
network namespace exits the cleanup gets stck in an
endless precessess of:

unregister_netdevice: waiting for lo to become free. Usage count = 3
unregister_netdevice: waiting for lo to become free. Usage count = 3
unregister_netdevice: waiting for lo to become free. Usage count = 3
unregister_netdevice: waiting for lo to become free. Usage count = 3
unregister_netdevice: waiting for lo to become free. Usage count = 3
unregister_netdevice: waiting for lo to become free. Usage count = 3
unregister_netdevice: waiting for lo to become free. Usage count = 3

It turns out that if you listen on a multicast address an unsubscribe
packet is sent when the network device goes down.   If you shutdown
the network namespace without carefully cleaning up this can trigger
the unsubscribe packet to be sent over the loopback interface while
the network namespace is going down.

All of which is fine except when we drop the packet and forget to
free it leaking the skb and the dst entry attached to.  As it
turns out the dst entry hold a reference to the idev which holds
the dev and keeps everything from being cleaned up.  Yuck!

By fixing my earlier thinko and add the needed kfree_skb and everything
cleans up beautifully.

A packet dequeued and stored as gso_skb in qdisc_peek_dequeued() should
be seen as part of the queue for sch->q.qlen queries until it's really
dequeued with qdisc_dequeue_peeked(), so qlen needs additional updating
in these functions. (Updating qstats.backlog shouldn't matter here.)

Subject: [PATCH 0237/1429] bonding: send IPv6 neighbor advertisement on
 failover

This patch adds better IPv6 failover support for bonding devices,
especially when in active-backup mode and there are only IPv6 addresses
configured, as reported by Alex Sidorenko.

- Creates a new file, net/drivers/bonding/bond_ipv6.c, for the
   IPv6-specific routines.  Both regular bonds and VLANs over bonds
   are supported.

- Adds a new tunable, num_unsol_na, to limit the number of unsolicited
   IPv6 Neighbor Advertisements that are sent on a failover event.
   Default is 1.

- Creates two new IPv6 neighbor discovery functions:

   ndisc_build_skb()
   ndisc_send_skb()

   These were required to support VLANs since we have to be able to
   add the VLAN id to the skb since ndisc_send_na() and friends
   shouldn't be asked to do this.  These two routines are basically
   __ndisc_send() split into two pieces, in a slightly different order.

- Updates Documentation/networking/bonding.txt and bumps the rev of bond
   support to 3.4.0.

On failover, this new code will generate one packet:

- An unsolicited IPv6 Neighbor Advertisement, which helps the switch
   learn that the address has moved to the new slave.

Testing has shown that sending just the NA results in pretty good
behavior when in active-back mode, I saw no lost ping packets for example.

Subject: [PATCH 0238/1429] bonding: Fix ALB mode to balance traffic on VLANs

	The current ALB function that processes incoming ARPs
does not handle traffic for VLANs configured above bonding.  This causes
traffic on those VLANs to all be assigned the same slave.  This patch
corrects that misbehavior by locating the bonding interface nested below
the VLAN interface.

	Bug reported by Sven Anders <anders@anduras.de>, who also
tested an earlier version of this patch and confirmed that it resolved
the problem.

Subject: [PATCH 0239/1429] bonding: alternate agg selection policies for
 802.3ad

	This patch implements alternative aggregator selection policies
for 802.3ad.  The existing policy, now termed "stable," selects the active
aggregator by greatest bandwidth, and only reselects a new aggregator
if the active aggregator is entirely disabled (no more ports or all ports
down).

	This patch adds two new policies: bandwidth and count, selecting
the active aggregator by total bandwidth (like the stable policy) or by
the number of ports in the aggregator, respectively.  These two policies
also differ from the stable policy in that they will reselect the active
aggregator when availability-related changes occur in the bond (e.g.,
link state change).

	This permits "gang failover" within 802.3ad, allowing redundant
aggregators along parallel paths to always maintain the "best" aggregator
as the active aggregator (rather than having to wait for the active to
entirely fail).

	This patch also updates the driver version to 3.5.0.

 EEPROM

Due to a hardware bug, the originally assigned range cannot reliably
be used for boot configuration and must not be modifiable through
ethtool.

Subject: [PATCH 0242/1429] sfc: Expose flash region storing boot code as MTD

The boot code that appears as a PCI expansion ROM on the SFC4000 is
stored in flash.  Expose this as a standard MTD device to allow for
in-place upgrades.

Subject: [PATCH 0243/1429] sfc: Use lm87 and lm90 drivers for board
 temperature/power monitoring

Add board monitoring to periodic work whenever link is down.
For SFE4001, report when a fault has caused the PHY to turn off.
For SFE4002, switch XFP PHY into low-power state in case of a fault.

Subject: [PATCH 0244/1429] sfc: Do not reset when hardware monitor detects a
 fault

The TX watchdog should trigger a reset, but a temperature/power alarm
should not as this is unlikely to solve the problem.

Subject: [PATCH 0246/1429] SMSC LAN911x and LAN921x vendor driver

Attached is a driver for SMSC's LAN911x and LAN921x families of embedded
ethernet controllers.

There is an existing smc911x driver in the tree; this is intended to
replace it.  Dustin McIntire (the author of the smc911x driver) has
expressed his support for switching to this driver.

This driver contains workarounds for all known hardware issues, and has
been tested on all flavours of the chip on multiple architectures.

This driver now uses phylib, so this patch also adds support for the
device's internal phy

Subject: [PATCH 0247/1429] net: mark flow_cache_cpu_prepare() as __init

It's called from __init code only. And__devinit in generic networking code

Subject: [PATCH 0252/1429] net: fib_rules ordering fixes.

the notifier.  Otherwise if a network device is already registered
we get a nasty NULL pointer dereference.

Subject: [PATCH 0253/1429] net: Guaranetee the proper ordering of the loopback
 device. v2

I was recently hunting a bug that occurred in network namespace
cleanup.  In looking at the code it became apparrent that we have
and will continue to have cases where if we have anything going
on in a network namespace there will be assumptions that the
loopback device is present.   Things like sending igmp unsubscribe
messages when we bring down network devices invokes the routing
code which assumes that at least the loopback driver is present.

Therefore to avoid magic initcall ordering hackery that is hard
to follow and hard to get right insert a call to register the
loopback device directly from net_dev_init().    This guarantes
that the loopback device is the first device registered and
the last network device to go away.

But do it carefully so we register the loopback device after
we clear dev_boot_phase.

Subject: [PATCH 0254/1429] pkt_sched: Control group classifier

The classifier should cover the most common use case and will work
without any special configuration.

The principle of the classifier is to directly access the
task_struct via get_current(). In order for this to work,
classification requests from softirqs must be ignored. This is
not a problem because the vast majority of packets in softirq
context are not assigned to a task anyway. For this to work, a
mechanism is needed to trace softirq context.

This repost goes back to the method of relying on the number of
nested bh disable calls for the sake of not adding too much
complexity and the option to come up with something more reliable
if actually needed.

Subject: [PATCH 0256/1429] netdevice libertas: Fix directly reference of
 netdev->priv

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

Different to readonly reference of netdev->priv, in this driver, netdev->priv
was changed. I use netdev->ml_priv to replace netdev->priv.

Subject: [PATCH 0257/1429] p54: introduce new names for device firmwares

Johannes thought it would have been a good idea to change the firmware names.

Note: we still have fallbacks in case our users don't want to "break their running system",
but we won't advertise them with MODULE_FIRMWARE.

Subject: [PATCH 0258/1429] p54: more definitions form lmac_longbow.h and pda.h

This patch ports more useful features to p54
  - PDR definitions for the synth chips & regulatory domain.
  - honour IEEE80211_TX_CTL_ASSIGN_SEQ flag, if it's set.
  - adds some lost mutex_lock & mutex_unlock.
  - replace two more "magic values" that sneaked past.

When an undirected scan is requested and iwlwifi is not associated but
the user has set an SSID (and maybe was associated with that network at
some point) then iwlwifi will assume the user wanted to scan for this
SSID which seems wrong. Remove this code.

Subject: [PATCH 0269/1429] b43/legacy: remove SSID code

The SSID programmed into the device is used by the ucode only
to reply to probe requests, a functionality we disable anyway
because it doesn't fit with the mac80211/hostapd programming
model. Therefore, it isn't useful to program the SSID into
device.

Subject: [PATCH 0270/1429] adm8211: remove SSID code

Since adm8211 currently doesn't implement IBSS mode anyway,
it can't be using the SSID. And if/when it does implement
IBSS mode, we'll have to see how to make it beacon anyway.

Subject: [PATCH 0271/1429] mac80211: remove SSID driver code

Remove the SSID from the driver API since now there is no
driver that requires knowing the SSID and I think it's
unlikely that any hardware design that does require the
SSID will play well with mac80211.

This also removes support for setting the SSID in master
mode which will require a patch to hostapd to not try.

Subject: [PATCH 0272/1429] iwl3945: remove bogus comment

I added this comment myself, but it's clearly wrong. I had meant
to place it in iwl_mac_add_interface, which at the time didn't
honour the MAC address setting, but it does now.

Subject: [PATCH 0273/1429] don't use net/ieee80211.h

Convert all the drivers using net/ieee80211.h to use linux/ieee80211.h.
Contains a bugfix in libertas where the SSID parsing could overrun the
buffer when the AP sends invalid information.

Subject: [PATCH 0274/1429] ath5k: Update PCU code

* In set_opmode don't handle antenna settings and preserve other STA_ID1 settings
(shouldn't matter because we call it during reset but it makes things cleaner)
Also set properly AP/ADHOC indicator flag on CFG while setting AP/ADHOC modes
and always enable key search mode.

* Properly set BSSID Mask during reset (cache it and reuse it durring set_associd)

* Update beacon_init to flush pending BMISS interrupts and handle setting of adhoc
beacon ATIM policy flag for ad-hoc mode. Also set TSF to 0 to start TSF increment
on AP mode. We need to handle sleep timers for AR5212 there + add support for PCF.

* Properly clean MIC key from keytable when TKIP is used (Bob is working on set_key
function etc so i leave it for now).

Tested on AR5212 (Hainan) and AR5413 and works fine

v2 Set PISR on AR5211+ and ISR on AR5210, got to sleep more ;-)

The TSF is already reset properly via mac80211's callback.
Resetting it in config_interface() is not needed.

Subject: [PATCH 0295/1429] rt2x00: Optimize configuration handling

Implement latest changed from mac80211 configuration
handling to optmize configuration handling in rt2x00.

 * Remove set_retry_limit callback function, handled
   through config()
 * Move config_antenna to its own callback function,
   it isn't handled by mac80211 anymore
 * Use IEEE80211_CONF_CHANGED_* flags and remove manual
   checks
 * Removed deprecated short slot setting through config()
   and put it in config_erp() through which mac80211 now
   configures it
 * Remove config_phymode() and move contents to config_erp()
   since it only managed the basic rates which is now
   determined by mac80211 through config_erp().

Subject: [PATCH 0296/1429] rt2x00: Remove ieee80211_bss_conf from rt2x00_intf

We can safely remove ieee80211_bss_conf from rt2x00_intf,
it is provided by mac80211 in ieee80211_vif as well.
(rt2x00_intf is the drv_priv field of ieee80211_vif).

Subject: [PATCH 0300/1429] rtl8187: Remove OFDM delays

Routine rtl8225_write_phy_ofdm() calls rtl8225_write_phy(), which concludes
with a sleep of 1 msec; therefore a call to rtl8225_write_phy_ofdm()
immediately followed by an msleep(1) is not needed.

From a3d67bc2e9e25f09151971192946fe3b68543649 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0301/1429] rtl8187: Remove CCK delays

Routine rtl8225_write_phy_cck() calls rtl8225_write_phy(), which concludes
with a sleep of 1 msec; therefore a call to rtl8225_write_phy_cck()
immediately followed by an msleep(1) is not needed.

Subject: [PATCH 0302/1429] rtl8187: Remove msleep calls after calls to
 rtl8225_write

Routine rtl8225_write() calls either rtl8225_write_bitbang() or
rtl8225_write_8051(), both of which end with an msleep() command. As a
result, a rtl8225_write() immediately followed by an msleep() is not needed.

Subject: [PATCH 0303/1429] rtl8187: Remove primitive write delays

Each of the primary write routines, rtl8187_write_phy(),
rtl8225_write_bitbang(), and rtl8225_write_8051() all conclude with an
msleep() command. Testing shows that these are not needed.

Subject: [PATCH 0304/1429] rtl8187: Reduce channel switch delay

The latest vendor driver (rtl8187B_linux_26.1036.0708.2008) has a 10 msec
delay after the call to set a new channel, but not before.

Subject: [PATCH 0306/1429] rt2x00: Remove debugfs CSR access wrappers

Move calculation of CSR register offset into rt2x00debug.c
and remove the wrapper functions from each individual driver.
(Except rt2500usb, which still needs to wrap for the
different value type argument).

Subject: [PATCH 0311/1429] iwlwifi: fix priv->iw_mode setting when multiple
 vif are configured

mac80211 supports multiple virtual interfaces for a single device. For
example, a managed interface (wlan0) and a monitor interface (mon0) can
exist at the same time. Thus priv->iw_mode is not sufficient to track
the wireless mode any more. The patch redefines priv->iw_mode as the
first interface mode (the same as priv->vif->type if priv->vif != NULL).
If another monitor type interface is created later, we don't change
priv->iw_mode into monitor. This way, the original interface still
works. The patch also requests mac80211 to do reassociation after we
change the Rx filter flags.

Subject: [PATCH 0326/1429] mac80211: Allow AP mode to be enabled

With the addition of basic rate set and TX queue parameter
configuration and confirmation that power save buffering is
working again, mac80211 is now in state that allows AP mode to be
used without major problems. Consequently, it is time to allow this
mode to be enabled without having to patch the kernel.

AP mode requires hostapd for management frame processing and as such,
configuring this mode is only allowed through cfg80211 (not with
iwconfig and WEXT).

Subject: [PATCH 0327/1429] mac80211_hwsim: Add support for client PS mode

This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be
used to force a simulated radio into power save mode. Following values
can be written into this file to change PS mode:
0 = power save disabled (constantly awake)
1 = power save enabled (drop all frames; do not send PS-Poll)
2 = power save enabled (send PS-Poll frames automatically to receive
    buffered unicast frames); not yet fully implemented
3 = manual PS-Poll trigger (send a single PS-Poll frame)

Two different behavior for power save mode processing can be tested:
- move between modes 1 and 0 (i.e., receive all buffered frames at a
  time)
- move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps'
  debugfs file) to fetch power save buffered frames one at a time

Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but
eventually, it should take a look at TIM IE and send PS-Poll if a
traffic bit is set for our AID.

Subject: [PATCH 0329/1429] cfg80211: Add regulatory domain intersection
 capability

There are certain scenerios where we require intersecting
two regulatory domains. This adds intersection support.
When we enable 802.11d support we will use this to intersect
the regulatory domain from the AP's country IE and what our
regulatory agent believes is correct for a country.

This patch enables intersection for now in the case where
the last regdomain was set by a country IE which was parsed
and the user then wants to set the regulatory domain. Since
we don't support country IE parsing yet this code path will not
be hit, however this allows us to pave the way for 11d support.

Intersection code has been tested in userspace with CRDA.

Subject: [PATCH 0336/1429] pktgen: add full reset functionality

While testing pktgen, I found that sometimes my configurations from
previous runs would be left over, particularly when going from a test
with 8 threads down to a test with 4 threads.

This adds new functionality to pktgen where you can call
pgset "reset"

and it will be just like you just insmod'ed pktgen again.

Subject: [PATCH 0340/1429] dccp: Limit feature negotiation to connection setup
 phase

This patch limits feature (capability) negotation to the connection setup phase:

 1. Although it is theoretically possible to perform feature negotiation at any
    time (and RFC 4340 supports this), in practice this is prohibitively complex,
    as it requires to put traffic on hold for each new negotiation.
 2. As a byproduct of restricting feature negotiation to connection setup, the
    feature-negotiation retransmit timer is no longer required. This part is now
    mapped onto the protocol-level retransmission.
    Details indicating why timers are no longer needed can be found on
    http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/feature_negotiation/\
	                                      implementation_notes.html

This patch disables anytime negotiation, subsequent patches work out full
feature negotiation support for connection setup.

Subject: [PATCH 0341/1429] dccp: Registration routines for changing feature
 values

Two registration routines, for SP and NN features, are provided by this patch,
replacing a previous routine which was used for both feature types.

These are internal-only routines and therefore start with `__feat_register'.

It further exports the known limits of Sequence Window and Ack Ratio as symbolic
constants.

Subject: [PATCH 0342/1429] dccp: Query supported CCIDs

This provides a data structure to record which CCIDs are locally supported
and three accessor functions:
 - a test function for internal use which is used to validate CCID requests
   made by the user;
 - a copy function so that the list can be used for feature-negotiation;
 - documented getsockopt() support so that the user can query capabilities.

The data structure is a table which is filled in at compile-time with the
list of available CCIDs (which in turn depends on the Kconfig choices).

Using the copy function for cloning the list of supported CCIDs is useful for
feature negotiation, since the negotiation is now with the full list of available
CCIDs (e.g. {2, 3}) instead of the default value {2}. This means negotiation
will not fail if the peer requests to use CCID3 instead of CCID2.

Subject: [PATCH 0343/1429] dccp: Resolve dependencies of features on choice of
 CCID

This provides a missing link in the code chain, as several features implicitly
depend and/or rely on the choice of CCID. Most notably, this is the Send Ack Vector
feature, but also Ack Ratio and Send Loss Event Rate (also taken care of).

For Send Ack Vector, the situation is as follows:
 * since CCID2 mandates the use of Ack Vectors, there is no point in allowing
   endpoints which use CCID2 to disable Ack Vector features such a connection;

 * a peer with a TX CCID of CCID2 will always expect Ack Vectors, and a peer
   with a RX CCID of CCID2 must always send Ack Vectors (RFC 4341, sec. 4);

 * for all other CCIDs, the use of (Send) Ack Vector is optional and thus
   negotiable. However, this implies that the code negotiating the use of Ack
   Vectors also supports it (i.e. is able to supply and to either parse or
   ignore received Ack Vectors). Since this is not the case (CCID-3 has no Ack
   Vector support), the use of Ack Vectors is here disabled, with a comment
   in the source code.

An analogous consideration arises for the Send Loss Event Rate feature,
since the CCID-3 implementation does not support the loss interval options
of RFC 4342. To make such use explicit, corresponding feature-negotiation
options are inserted which signal the use of the loss event rate option,
as it is used by the CCID3 code.

Lastly, the values of the Ack Ratio feature are matched to the choice of CCID.

The patch implements this as a function which is called after the user has
made all other registrations for changing default values of features.

The table is variable-length, the reserved (and hence for feature-negotiation
invalid, confirmed by considering section 19.4 of RFC 4340) feature number `0'
is used to mark the end of the table.

Subject: [PATCH 0344/1429] net: Introduce read_pnet() and write_pnet() helpers

This patch introduces two helpers that deal with reading and writing
struct net pointers in various network structures.

Their implementation depends on CONFIG_NET_NS

For symmetry, both functions work with "struct net **pnet".

Their usage should reduce the number of #ifdef CONFIG_NET_NS,
without adding many helpers for each network structure
that hold a "struct net *pointer"

In commit 2518c7c2b3d7f0a6b302b4efe17c911f8dd4049f ("[XFRM]: Hash
policies when non-prefixed."), the last use of xfrm_gen_policy() first
argument was removed, but the argument was left behind in the
prototype.

Subject: [PATCH 0354/1429] netdevice: safe convert to netdev_priv() #part-1

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.

Subject: [PATCH 0355/1429] netdevice: safe convert to netdev_priv() #part-2

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.

Subject: [PATCH 0356/1429] netdevice: safe convert to netdev_priv() #part-3

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.

Subject: [PATCH 0357/1429] netdevice: safe convert to netdev_priv() #part-4

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.

Subject: [PATCH 0358/1429] isdn: use %pI4, remove get_{u8/u16/u32} and
 put_{u8/u16/u32} inlines

They would have been better named as get_be16, put_be16, etc.
as they were hiding an endian shift inside.

They don't add much over explicitly coding the byteshifting
and gcc sometimes has a problem with builtin_constant_p inside
inline functions, so it may do a better job of byteswapping
at compile time rather than runtime.

Subject: [PATCH 0360/1429] pkt_sched: Remove qdisc->ops->requeue() etc.

After implementing qdisc->ops->peek() and changing sch_netem into
classless qdisc there are no more qdisc->ops->requeue() users. This
patch removes this method with its wrappers (qdisc_requeue()), and
also unused qdisc->requeue structure. There are a few minor fixes of
warnings (htb_enqueue()) and comments btw.

The idea to kill ->requeue() and a similar patch were first developed
by David S. Miller.

Subject: [PATCH 0361/1429] net: speedup dst_release()

During tbench/oprofile sessions, I found that dst_release() was in third position.

CPU: Core 2, speed 2999.68 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask of 0x00 (Unhalted core cycles) count 100000
samples  %        symbol name

95067     1.7724  __copy_from_user_ll
86531     1.6133  tcp_transmit_skb

Of course, all CPUS fight on the dst_entry associated with 127.0.0.1

Instead of first checking the refcount value, then decrement it,
we use atomic_dec_return() to help CPU to make the right memory transaction
(ie getting the cache line in exclusive mode)

dst_release() is now at the fifth position, and tbench a litle bit faster ;)

Subject: [PATCH 0362/1429] ixgbe: Fix usage of netif_*_all_queues() with
 netif_carrier_{off|on}()

netif_carrier_off() is sufficient to stop Tx into the driver.  Stopping the Tx
queues is redundant and unnecessary.  By the same token, netif_carrier_on()
will be sufficient to re-enable Tx, so waking the queues is unnecessary.

Subject: [PATCH 0363/1429] pegasus: minor resource shrinkage

Make pegasus driver not allocate a workqueue until the driver
is bound to some device, which will need that workqueue if
the device is brought up.  This conserves resources when the
driver is linked but there's no pegasus device connected.

Also shrink the runtime footprint a smidgeon by moving some
init-only code into its proper section, and move an obnoxious
(frequent and meaningless) message to be debug-only.

Subject: [PATCH 0366/1429] phylib: make mdio-gpio work without OF (v4)

make mdio-gpio work with non OpenFirmware gpio implementation.

Aditional changes to mdio-gpio:
- use gpio_request() and gpio_free()
- place irq[] array in struct mdio_gpio_info
- add module description, author and license
- add note about compiling this driver as module
- rename mdc and mdio function (were ugly names)
- change MII to MDIO in bus name
- add __init __exit to module (un)loading functions
- probe fails if no phys added to the bus
- kzalloc bitbang with sizeof(*bitbang)

Changes since v3:
- keep bus naming "%x" to be compatible with existing drivers.

Changes since v2:
- more #ifdefs reduction
- platform driver will be registered on OF platforms also
- unified platform and OF bus_id to phy%i

Changes since v1:
- removed NO_IRQ
- reduced #idefs

Laurent, please test this driver under OF.

The attached patch makes it work much better for me.  The patch
will cause the code to NOT create a stale neighbor entry if we
are not going to respond to the ARP request.  The old code
*would* create a stale entry even if we are not going to respond.

Subject: [PATCH 0369/1429] TPROXY: implemented IP_RECVORIGDSTADDR socket
 option

In case UDP traffic is redirected to a local UDP socket,
the originally addressed destination address/port
cannot be recovered with the in-kernel tproxy.

This patch adds an IP_RECVORIGDSTADDR sockopt that enables
a IP_ORIGDSTADDR ancillary message in recvmsg(). This
ancillary message contains the original destination address/port
of the packet being received.

Subject: [PATCH 0370/1429] rcu: Introduce hlist_nulls variant of hlist

hlist uses NULL value to finish a chain.

hlist_nulls variant use the low order bit set to 1 to signal an end-of-list marker.

This allows to store many different end markers, so that some RCU lockless
algos (used in TCP/UDP stack for example) can save some memory barriers in
fast paths.

Two new files are added :

include/linux/list_nulls.h
  - mimics hlist part of include/linux/list.h, derived to hlist_nulls variant

include/linux/rculist_nulls.h
  - mimics hlist part of include/linux/rculist.h, derived to hlist_nulls variant

   Only four helpers are declared for the moment :

     hlist_nulls_del_init_rcu(), hlist_nulls_del_rcu(),
     hlist_nulls_add_head_rcu() and hlist_nulls_for_each_entry_rcu()

prefetches() were removed, since an end of list is not anymore NULL value.
prefetches() could trigger useless (and possibly dangerous) memory transactions.

Example of use (extracted from __udp4_lib_lookup())

	struct sock *sk, *result;
        struct hlist_nulls_node *node;
        unsigned short hnum = ntohs(dport);
        unsigned int hash = udp_hashfn(net, hnum);
        struct udp_hslot *hslot = &udptable->hash[hash];
        int score, badness;

        rcu_read_lock();
begin:
        result = NULL;
        badness = -1;
        sk_nulls_for_each_rcu(sk, node, &hslot->head) {
                score = compute_score(sk, net, saddr, hnum, sport,
                                      daddr, dport, dif);
                if (score > badness) {
                        result = sk;
                        badness = score;
                }
        }
        /*
         * if the nulls value we got at the end of this lookup is
         * not the expected one, we must restart lookup.
         * We probably met an item that was moved to another chain.
         */
        if (get_nulls_value(node) != hash)
                goto begin;

        if (result) {
                if (unlikely(!atomic_inc_not_zero(&result->sk_refcnt)))
                        result = NULL;
                else if (unlikely(compute_score(result, net, saddr, hnum, sport,
                                  daddr, dport, dif) < badness)) {
                        sock_put(result);
                        goto begin;
                }
        }
        rcu_read_unlock();
        return result;

Subject: [PATCH 0371/1429] udp: Use hlist_nulls in UDP RCU code

This is a straightforward patch, using hlist_nulls infrastructure.

RCUification already done on UDP two weeks ago.

Using hlist_nulls permits us to avoid some memory barriers, both
at lookup time and delete time.

Patch is large because it adds new macros to include/net/sock.h.
These macros will be used by TCP & DCCP in next patch.

From 3ab5aee7fe840b5b1b35a8d1ac11c3de5281e611 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <dada1@cosmosbay.com>
Date: Sun, 16 Nov 2008 19:40:17 -0800
Subject: [PATCH 0372/1429] net: Convert TCP & DCCP hash tables to use RCU /
 hlist_nulls

RCU was added to UDP lookups, using a fast infrastructure :
- sockets kmem_cache use SLAB_DESTROY_BY_RCU and dont pay the
  price of call_rcu() at freeing time.
- hlist_nulls permits to use few memory barriers.

This patch uses same infrastructure for TCP/DCCP established
and timewait sockets.

Thanks to SLAB_DESTROY_BY_RCU, no slowdown for applications
using short lived TCP connections. A followup patch, converting
rwlocks to spinlocks will even speedup this case.

__inet_lookup_established() is pretty fast now we dont have to
dirty a contended cache line (read_lock/read_unlock)

Only established and timewait hashtable are converted to RCU
(bind table and listen table are still using traditional locking)

Subject: [PATCH 0373/1429] rcu: documents rculist_nulls

+Using hlist_nulls to protect read-mostly linked lists and
+objects using SLAB_DESTROY_BY_RCU allocations.
+
+Please read the basics in Documentation/RCU/listRCU.txt
+
+Using special makers (called 'nulls') is a convenient way
+to solve following problem :
+
+A typical RCU linked list managing objects which are
+allocated with SLAB_DESTROY_BY_RCU kmem_cache can
+use following algos :
+
+1) Lookup algo
+--------------
+rcu_read_lock()
+begin:
+obj = lockless_lookup(key);
+if (obj) {
+  if (!try_get_ref(obj)) // might fail for free objects
+    goto begin;
+  /*
+   * Because a writer could delete object, and a writer could
+   * reuse these object before the RCU grace period, we
+   * must check key after geting the reference on object
+   */
+  if (obj->key != key) { // not the object we expected
+     put_ref(obj);
+     goto begin;
+   }
+}
+rcu_read_unlock();
+
+Beware that lockless_lookup(key) cannot use traditional hlist_for_each_entry_rcu()
+but a version with an additional memory barrier (smp_rmb())
+
+lockless_lookup(key)
+{
+   struct hlist_node *node, *next;
+   for (pos = rcu_dereference((head)->first);
+          pos && ({ next = pos->next; smp_rmb(); prefetch(next); 1; }) &&
+          ({ tpos = hlist_entry(pos, typeof(*tpos), member); 1; });
+          pos = rcu_dereference(next))
+      if (obj->key == key)
+         return obj;
+   return NULL;
+
+And note the traditional hlist_for_each_entry_rcu() misses this smp_rmb() :
+
+   struct hlist_node *node;
+   for (pos = rcu_dereference((head)->first);
+		pos && ({ prefetch(pos->next); 1; }) &&
+		({ tpos = hlist_entry(pos, typeof(*tpos), member); 1; });
+		pos = rcu_dereference(pos->next))
+      if (obj->key == key)
+         return obj;
+   return NULL;
+}
+
+Quoting Corey Minyard :
+
+"If the object is moved from one list to another list in-between the
+ time the hash is calculated and the next field is accessed, and the
+ object has moved to the end of a new list, the traversal will not
+ complete properly on the list it should have, since the object will
+ be on the end of the new list and there's not a way to tell it's on a
+ new list and restart the list traversal.  I think that this can be
+ solved by pre-fetching the "next" field (with proper barriers) before
+ checking the key."
+
+2) Insert algo :
+----------------
+
+We need to make sure a reader cannot read the new 'obj->obj_next' value
+and previous value of 'obj->key'. Or else, an item could be deleted
+from a chain, and inserted into another chain. If new chain was empty
+before the move, 'next' pointer is NULL, and lockless reader can
+not detect it missed following items in original chain.
+
+/*
+ * Please note that new inserts are done at the head of list,
+ * not in the middle or end.
+ */
+obj = kmem_cache_alloc(...);
+lock_chain(); // typically a spin_lock()
+obj->key = key;
+atomic_inc(&obj->refcnt);
+/*
+ * we need to make sure obj->key is updated before obj->next
+ */
+smp_wmb();
+hlist_add_head_rcu(&obj->obj_node, list);
+unlock_chain(); // typically a spin_unlock()
+
+
+3) Remove algo
+--------------
+Nothing special here, we can use a standard RCU hlist deletion.
+But thanks to SLAB_DESTROY_BY_RCU, beware a deleted object can be reused
+very very fast (before the end of RCU grace period)
+
+if (put_last_reference_on(obj) {
+   lock_chain(); // typically a spin_lock()
+   hlist_del_init_rcu(&obj->obj_node);
+   unlock_chain(); // typically a spin_unlock()
+   kmem_cache_free(cachep, obj);
+}
+
+
+
+--------------------------------------------------------------------------
+With hlist_nulls we can avoid extra smp_rmb() in lockless_lookup()
+and extra smp_wmb() in insert function.
+
+For example, if we choose to store the slot number as the 'nulls'
+end-of-list marker for each slot of the hash table, we can detect
+a race (some writer did a delete and/or a move of an object
+to another chain) checking the final 'nulls' value if
+the lookup met the end of chain. If final 'nulls' value
+is not the slot number, then we must restart the lookup at
+the begining. If the object was moved to same chain,
+then the reader doesnt care : It might eventually
+scan the list again without harm.
+
+
+1) lookup algo
+
+ head = &table[slot];
+ rcu_read_lock();
+begin:
+ hlist_nulls_for_each_entry_rcu(obj, node, head, member) {
+   if (obj->key == key) {
+      if (!try_get_ref(obj)) // might fail for free objects
+         goto begin;
+      if (obj->key != key) { // not the object we expected
+         put_ref(obj);
+         goto begin;
+      }
+  goto out;
+ }
+/*
+ * if the nulls value we got at the end of this lookup is
+ * not the expected one, we must restart lookup.
+ * We probably met an item that was moved to another chain.
+ */
+ if (get_nulls_value(node) != slot)
+   goto begin;
+ obj = NULL;
+
+out:
+ rcu_read_unlock();
+
+2) Insert function :
+--------------------
+
+/*
+ * Please note that new inserts are done at the head of list,
+ * not in the middle or end.
+ */
+obj = kmem_cache_alloc(cachep);
+lock_chain(); // typically a spin_lock()
+obj->key = key;
+atomic_set(&obj->refcnt, 1);
+/*
+ * insert obj in RCU way (readers might be traversing chain)
+ */
+hlist_nulls_add_head_rcu(&obj->obj_node, list);
+unlock_chain(); // typically a spin_unlock()

Subject: [PATCH 0374/1429] net: make sure struct dst_entry refcount is aligned
 on 64 bytes

As found in the past (commit f1dd9c379cac7d5a76259e7dffcd5f8edc697d17
[NET]: Fix tbench regression in 2.6.25-rc1), it is really
important that struct dst_entry refcount is aligned on a cache line.

We cannot use __atribute((aligned)), so manually pad the structure
for 32 and 64 bit arches.

for 32bit : offsetof(truct dst_entry, __refcnt) is 0x80
for 64bit : offsetof(truct dst_entry, __refcnt) is 0xc0

As it is not possible to guess at compile time cache line size,
we use a generic value of 64 bytes, that satisfies many current arches.
(Using 128 bytes alignment on 64bit arches would waste 64 bytes)

Add a BUILD_BUG_ON to catch future updates to "struct dst_entry" dont
break this alignment.

"tbench 8" is 4.4 % faster on a dual quad core (HP BL460c G1), Intel E5450 @3.00GHz
(2350 MB/s instead of 2250 MB/s)

Subject: [PATCH 0376/1429] virtio_net: Recycle some more rx buffer pages

Each time we re-fill the recv queue with buffers, we allocate
one too many skbs and free it again when adding fails. We should
recycle the pages allocated in this case.

A previous version of this patch made trim_pages() trim trailing
unused pages from skbs with some paged data, but this actually
caused a barely measurable slowdown.

Seems like an oversight that we have set-tx-csum and set-sg hooked
up, but not set-tso.

Also leads to the strange situation that if you e.g. disable tx-csum,
then tso doesn't get disabled.

Subject: [PATCH 0378/1429] virtio_net: VIRTIO_NET_F_MSG_RXBUF (imprive rcv
 buffer allocation)

If segmentation offload is enabled by the host, we currently allocate
maximum sized packet buffers and pass them to the host. This uses up
20 ring entries, allowing us to supply only 20 packet buffers to the
host with a 256 entry ring. This is a huge overhead when receiving
small packets, and is most keenly felt when receiving MTU sized
packets from off-host.

The VIRTIO_NET_F_MRG_RXBUF feature flag is set by hosts which support
using receive buffers which are smaller than the maximum packet size.
In order to transfer large packets to the guest, the host merges
together multiple receive buffers to form a larger logical buffer.
The number of merged buffers is returned to the guest via a field in
the virtio_net_hdr.

Make use of this support by supplying single page receive buffers to
the host. On receive, we extract the virtio_net_hdr, copy 128 bytes of
the payload to the skb's linear data buffer and adjust the fragment
offset to point to the remaining data. This ensures proper alignment
and allows us to not use any paged data for small packets. If the
payload occupies multiple pages, we simply append those pages as
fragments and free the associated skbs.

This scheme allows us to be efficient in our use of ring entries
while still supporting large packets. Benchmarking using netperf from
an external machine to a guest over a 10Gb/s network shows a 100%
improvement from ~1Gb/s to ~2Gb/s. With a local host->guest benchmark
with GSO disabled on the host side, throughput was seen to increase
from 700Mb/s to 1.7Gb/s.

Based on a patch from Herbert Xu.

Subject: [PATCH 0379/1429] dccp: Mechanism to resolve CCID dependencies

This adds a hook to resolve features whose value depends on the choice of
CCID. It is done at the server since it can only be done after the CCID
values have been negotiated; i.e. the client will add its CCID preference
list on the Change options sent in the Request, which will be reconciled
with the local preference list of the server.

The concept is documented on
http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/feature_negotiation/\
				implementation_notes.html#ccid_dependencies

Subject: [PATCH 0380/1429] dccp: Deprecate old setsockopt framework

The previous setsockopt interface, which passed socket options via struct
dccp_so_feat, is complicated/difficult to use. Continuing to support it leads to
ugly code since the old approach did not distinguish between NN and SP values.

This patch removes the old setsockopt interface and replaces it with two new
functions to register NN/SP values for feature negotiation.
These are essentially wrappers around the internal __feat_register functions,
with checking added to avoid

 * wrong usage (type);
 * changing values while the connection is in progress.

Subject: [PATCH 0381/1429] dccp: Feature negotiation for
 minimum-checksum-coverage

This provides feature negotiation for server minimum checksum coverage
which so far has been missing.

Since sender/receiver coverage values range only from 0...15, their
type has also been reduced in size from u16 to u4.

Feature-negotiation options are now generated for both sender and receiver
coverage, i.e. when the peer has `forgotten' to enable partial coverage
then feature negotiation will automatically enable (negotiate) the partial
coverage value for this connection.

Subject: [PATCH 0382/1429] dccp: Deprecate Ack Ratio sysctl

This patch deprecates the Ack Ratio sysctl, since
 * Ack Ratio is entirely ignored by CCID-3 and CCID-4,
 * Ack Ratio currently doesn't work in CCID-2 (i.e. is always set to 1);
 * even if it would work in CCID-2, there is no point for a user to change it:
   - Ack Ratio is constrained by cwnd (RFC 4341, 6.1.2),
   - if Ack Ratio > cwnd, the system resorts to spurious RTO timeouts
     (since waiting for Acks which will never arrive in this window),
   - cwnd is not a user-configurable value.

The only reasonable place for Ack Ratio is to print it for debugging. It is
planned to do this later on, as part of e.g. dccp_probe.

With this patch Ack Ratio is now under full control of feature negotiation:
 * Ack Ratio is resolved as a dependency of the selected CCID;
 * if the chosen CCID supports it (i.e. CCID == CCID-2), Ack Ratio is set to
   the default of 2, following RFC 4340, 11.3 - "New connections start with Ack
   Ratio 2 for both endpoints";
 * what happens then is part of another patch set, since it concerns the
   dynamic update of Ack Ratio while the connection is in full flight.

Thanks to Tomasz Grobelny for discussion leading up to this patch.

Subject: [PATCH 0383/1429] dccp: Tidy up setsockopt calls

This splits the setsockopt calls into two groups, depending on whether an
integer argument (val) is required and whether routines being called do
their own locking.

Some options (such as setting the CCID) use u8 rather than int, so that for
these the test with regard to integer-sizeof can not be used.

The second switch-case statement now only has those statements which need
locking and which make use of `val'.

Subject: [PATCH 0387/1429] net: af_unix can make unix_nr_socks visbile in
 /proc

Currently, /proc/net/protocols displays socket counts only for TCP/TCPv6
protocols

We can provide unix_nr_socks for free here, this counter being
already maintained in af_unix

Before patch :

# grep UNIX /proc/net/protocols
UNIX       428     -1      -1   NI       0   yes  kernel

After patch :

# grep UNIX /proc/net/protocols
UNIX       428     98      -1   NI       0   yes  kernel

Subject: [PATCH 0388/1429] net: af_unix should update its inuse counter

This patch is a preparation to namespace conversion of /proc/net/protocols

In order to have relevant information for UNIX protocol, we should use
sock_prot_inuse_add() to update a (percpu and pernamespace) counter of
inuse sockets.

Subject: [PATCH 0389/1429] net: sctp should update its inuse counter

This patch is a preparation to namespace conversion of /proc/net/protocols

In order to have relevant information for SCTP protocols, we should use
sock_prot_inuse_add() to update a (percpu and pernamespace) counter of
inuse sockets.

Subject: [PATCH 0394/1429] netfilter: ctnetlink: helper modules load-on-demand
 support

This patch adds module loading for helpers via ctnetlink.

* Creation path: We support explicit and implicit helper assignation. For
  the explicit case, we try to load the module. If the module is correctly
  loaded and the helper is present, we return EAGAIN to re-start the
  creation. Otherwise, we return EOPNOTSUPP.
* Update path: release the spin lock, load the module and check. If it is
  present, then return EAGAIN to re-start the update.

This patch provides a refactorized function to lookup-and-set the
connection tracking helper. The function removes the exported symbol
__nf_ct_helper_find as it has not clients anymore.

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: Tue, 18 Nov 2008 11:56:20 +0100
Subject: [PATCH 0395/1429] netfilter: ctnetlink: deliver events for conntracks
 changed from userspace

As for now, the creation and update of conntracks via ctnetlink do not
propagate an event to userspace. This can result in inconsistent situations
if several userspace processes modify the connection tracking table by means
of ctnetlink at the same time. Specifically, using the conntrack command
line tool and conntrackd at the same time can trigger unconsistencies.

This patch also modifies the event cache infrastructure to pass the
process PID and the ECHO flag to nfnetlink_send() to report back
to userspace if the process that triggered the change needs so.
Based on a suggestion from Patrick McHardy.

Subject: [PATCH 0398/1429] net: af_packet should update its inuse counter

This patch is a preparation to namespace conversion of /proc/net/protocols

In order to have relevant information for PACKET protocols, we should use
sock_prot_inuse_add() to update a (percpu and pernamespace) counter of
inuse sockets.

Subject: [PATCH 0399/1429] net: make /proc/net/protocols namespace aware

Converting /proc/net/protocols to be namespace aware is quite easy
and permits us to use sock_prot_inuse_get().

This provides seperate counters for each protocol. For example
we can really count TCPv6 sockets and TCPv4 sockets, while previously,
we had the same value, and this value was not namespace aware.

Subject: [PATCH 0404/1429] netdev: network device operations infrastructure

This patch changes the network device internal API to move adminstrative
operations out of the network device structure and into a separate structure.

This patch involves some hackery to maintain compatablity between the
new and old model, so all 300+ drivers don't have to be changed at once.
For drivers that aren't converted yet, the netdevice_ops virt function list
still resides in the net_device structure. For old protocols, the new
net_device_ops are copied out to the old net_device pointers.

After the transistion is completed the nag message can be changed to
an WARN_ON, and the compatiablity code can be made configurable.

Some function pointers aren't moved:
* destructor can't be in net_device_ops because
  it may need to be referenced after the module is unloaded.
* neighbor setup is manipulated in a couple of places that need special
  consideration
* hard_start_xmit is in the fast path for transmit.

From eeda3fd64f75bcbfaa70ce946513abaf3f23b8e0 Mon Sep 17 00:00:00 2001
From: Stephen Hemminger <shemminger@vyatta.com>
Date: Wed, 19 Nov 2008 21:40:23 -0800
Subject: [PATCH 0405/1429] netdev: introduce dev_get_stats()

In order for the network device ops get_stats call to be immutable, the handling
of the default internal network device stats block has to be changed. Add a new
helper function which replaces the old use of internal_get_stats.

Note: change return code to make it clear that the caller should not
go changing the returned statistics.

Subject: [PATCH 0414/1429] bonding: convert to net_device_ops

Convert to net_device_ops table.
Note: for some operations move error checking into generic networking
layer (rather than looking at pointers in bonding).

A couple of gratituous style cleanups to get rid of extra {}

Subject: [PATCH 0416/1429] sky2: convert to net_device_ops

Convert to new network device ops interface. Slight additional complexity
here because the second port does not allow netpoll and therefore has
different virtual function table.

Subject: [PATCH 0436/1429] net: listening_hash get a spinlock per bucket

This patch prepares RCU migration of listening_hash table for
TCP/DCCP protocols.

listening_hash table being small (32 slots per protocol), we add
a spinlock for each slot, instead of a single rwlock for whole table.

This should reduce hold time of readers, and writers concurrency.

Subject: [PATCH 0438/1429] igb: simplify swap in clean_rx_irq if using packet
 split

This update replaces the xchg calls that were added with a pair of
assignments as there is no need for the xchg calls and they were found to
cause issues on some architectures.

Subject: [PATCH 0439/1429] igb: Fix tx/rx_ring_count parameters for igb on
 suspend/resume/ring resize

When suspending the device the ring structure is freed which causes it to
loose track of the count.  To resolve this we need to move the ring count
outside of the ring structure and store it in the adapter struct.

In addition to resolving the suspend/resume issue this patch also addresses
issues seen in the event of memory allocation errors causing uneven ring
sizes on multiple queues.

stream of netlink attributes from one offset to the end of the
netlink message. This is not suitable to look for a specific
matching inside a set of nested attributes.

For example, in ctnetlink messages, if we look for the CTA_V6_SRC
attribute in a message that talks about an IPv4 connection,
SKF_AD_NLATTR returns the offset of CTA_STATUS which has the same
value of CTA_V6_SRC but outside the nest. To differenciate
CTA_STATUS and CTA_V6_SRC, we would have to make assumptions on the
size of the attribute and the usual offset, resulting in horrible
BSF code.

This patch adds SKF_AD_NLATTR_NEST, which is a variant of
SKF_AD_NLATTR, that looks for an attribute inside the limits of
a nested attributes, but not further.

This patch validates that we have enough room to look for the
nested attributes - based on a suggestion from Patrick McHardy.

Subject: [PATCH 0443/1429] netdevice: 82596: Convert netdev->priv to
 netdev_priv

1. When alloc_etherdev(), no memory be allocated to netdev->priv.
2. And it's need to get a whole page for priv.

For these reasons, use netdev->ml_priv to point to the page is the
best method to convert directly reference of netdev->priv.

Subject: [PATCH 0452/1429] mv643xx_eth: introduce per-port register area
 pointer

The mv643xx_eth driver uses the rdl()/wrl() macros to read and
write hardware registers.  Per-port registers are accessed in the
following way:

	#define PORT_STATUS(p)			(0x0444 + ((p) << 10))

	[...]

	static inline u32 rdl(struct mv643xx_eth_private *mp, int offset)
	{
		return readl(mp->shared->base + offset);
	}

	[...]

	port_status = rdl(mp, PORT_STATUS(mp->port_num));

By giving the per-port 'struct mv643xx_eth_private' its own
'void __iomem *base' pointer that points to the per-port register
area, we can get rid of both the double indirection and the << 10
that is done for every per-port register access -- this patch does
that.

Subject: [PATCH 0453/1429] mv643xx_eth: inline txq_alloc_desc_index()

Since txq_alloc_desc_index() is a very simple function, and since
descriptor ring index handling for transmit reclaim, receive
processing and receive refill is already handled inline as well,
inline txq_alloc_desc_index() into its two call sites.

Subject: [PATCH 0454/1429] mv643xx_eth: implement ->set_rx_mode()

Currently, if multiple unicast addresses are programmed into a
mv643xx_eth interface, the core networking will resort to enabling
promiscuous mode on the interface, as mv643xx_eth does not implement
->set_rx_mode().

This patch switches mv643xx_eth over from ->set_multicast_list()
to ->set_rx_mode(), and implements support for secondary unicast
addresses.  The hardware can handle multiple unicast addresses as
long as their first 11 nibbles are the same (i.e. are of the form
xx:xx:xx:xx:xx:xy where the x part is the same for all addresses), so
if that is the case, we use that mode.  If it's not the case, we enable
unicast promiscuous mode in the hardware, which is slightly better than
enabling promiscuous mode for multicasts as well, which is what would
happen before.

While we are at it, change the programming sequence so that we
don't clear all filter bits first, so we don't lose all incoming
packets while the filter is being reprogrammed.

Subject: [PATCH 0457/1429] netdevice lance: Convert directly reference of
 netdev->priv

This patch is to kill directly reference of netdev->priv too.
Because the private data should be allocated in DMA area, alloc_etherdev()
can't satisfy this needs.
Use netdev->ml_priv to point to lance_private.

A netlink attribute padding of zero triggers this sparse warning:

include/linux/netlink.h:245:8: warning: memset with byte count of 0

Avoid the memset when the size parameter is constant and requires no padding.

Subject: [PATCH 0459/1429] pkt_sched: add DRR scheduler

Add classful DRR scheduler as a more flexible replacement for SFQ.

The main difference to the algorithm described in "Efficient Fair Queueing
using Deficit Round Robin" is that this implementation doesn't drop packets
from the longest queue on overrun because its classful and limits are
handled by each individual child qdisc.

Subject: [PATCH 0462/1429] pkt_sched: remove unnecessary xchg() in packet
 classifiers

The use of xchg() hasn't been necessary since 2.2.something when proper
locking was added to packet schedulers. In the case of classifiers they
mostly weren't even necessary before that since they're mainly used
to assign a NULL pointer to the filter root in the ->destroy path;
the root is destroyed immediately after that.

Subject: [PATCH 0464/1429] smsc95xx: add tx checksum offload support

LAN9500 supports tx checksum offload, which slightly decreases cpu
utilisation.  The benefit isn't very large because we still require
the skb to be linearized, but it does save a few cycles.

This patch adds support for it, and enables it by default.

Subject: [PATCH 0466/1429] netdevice ni65: Convert directly reference of
 netdev->priv

This patch is to kill directly reference of netdev->priv too.
Because the private data needs special memory: lower 16MB DMA.
alloc_etherdev() can not do this work.
So we can't use netdev->priv to point to netdev's private data.
Use netdev->ml_priv instead.

Subject: [PATCH 0468/1429] netfilter: ip{,6}t_policy.h should include
 xp_policy.h

It seems that all of the include/netfilter_{ipv4,ipv6}/{ipt,ip6t}_*.h which
share constants include the corresponding include/netfilter/xp_*.h files.
Neither ipt_policy.h not ip6t_policy.h do.  Make these consistant with
the norm.

Subject: [PATCH 0469/1429] netdev: add more functions to netdevice ops

This patch moves neigh_setup and hard_start_xmit into the network device ops
structure. For bisection, fix all the previously converted drivers as well.
Bonding driver took the biggest hit on this.

Added a prefetch of the hard_start_xmit in the fast path to try and reduce
any impact this would have.

Subject: [PATCH 0475/1429] ipip: convert to net_device_ops

Convert to network device ops. Needed to change to directly call
the init routine since two sides share same ops.  In the process
found by inspection a device ref count leak if register_netdevice failed.

Subject: [PATCH 0478/1429] net: convert TCP/DCCP ehash rwlocks to spinlocks

Now TCP & DCCP use RCU lookups, we can convert ehash rwlocks to spinlocks.

/proc/net/tcp and other seq_file 'readers' can safely be converted to 'writers'.

This should speedup writers, since spin_lock()/spin_unlock()
only use one atomic operation instead of two for write_lock()/write_unlock()

Subject: [PATCH 0479/1429] ixgbe: this patch adds support for DCB to the
 kernel and ixgbe driver

This adds support for Data Center Bridging (DCB) features in the ixgbe
driver and adds an rtnetlink interface for configuring DCB to the
kernel.  The DCB feature support included are Priority Grouping (PG) -
which allows bandwidth guarantees to be allocated to groups to traffic
based on the 802.1q priority, and Priority Based Flow Control (PFC) -
which introduces a new MAC control PAUSE frame which works at
granularity of the 802.1p priority instead of the link (IEEE 802.3x).

+/**
+ * Data Center Bridging (DCB) is a collection of Ethernet enhancements
+ * intended to allow network traffic with differing requirements
+ * (highly reliable, no drops vs. best effort vs. low latency) to operate
+ * and co-exist on Ethernet.  Current DCB features are:
+ *
+ * Enhanced Transmission Selection (aka Priority Grouping [PG]) - provides a
+ *   framework for assigning bandwidth guarantees to traffic classes.
+ *
+ * Priority-based Flow Control (PFC) - provides a flow control mechanism which
+ *   can work independently for each 802.1p priority.
+ *
+ * Congestion Notification - provides a mechanism for end-to-end congestion
+ *   control for protocols which do not have built-in congestion management.
+ *
+ * More information about the emerging standards for these Ethernet features
+ * can be found at: http://www.ieee802.org/1/pages/dcbridges.html
+ *
+ * This file implements an rtnetlink interface to allow configuration of DCB
+ * features for capable devices.

From: Alexander Duyck <alexander.h.duyck@intel.com>
Date: Thu, 20 Nov 2008 21:08:19 -0800
Subject: [PATCH 0481/1429] DCB: Add interface to query # of TCs supported by
 device

Adds interface for Data Center Bridging (DCB) to query (and set if
supported) the number of traffic classes currently supported by the
device for the two (DCB) features: priority groups (PG) and priority
flow control (PFC).

Subject: [PATCH 0482/1429] DCB: Add interface to query the state of PFC
 feature.

Adds a netlink interface for Data Center Bridging (DCB) to get and set
the enable state of the Priority Flow Control (PFC) feature.
Primarily, this is a way to turn off PFC in the driver while DCB
remains enabled.

Subject: [PATCH 0483/1429] DCB: Add support for DCB BCN

Adds an interface to configure the Backward Congestion Notification
(BCN) feature.  In a BCN capabale network, congestion notifications
from congested points out in the network can cause the end station
limit the rate of a given traffic flow.

From c4900be053d376dfe4f603d000aa5e4c60745dec Mon Sep 17 00:00:00 2001
From: Donald Skidmore <donald.c.skidmore@intel.com>
Date: Thu, 20 Nov 2008 21:11:42 -0800
Subject: [PATCH 0484/1429] ixgbe: add SFP+ driver support

This patch adds support for SFP+ PHY in the following device ID's (10DB,
10F1, 10E1).  These SFP+ PHY's are accessed via an I2C interface so the
patch also includes functions to support this.

Another feature of note is that the PHY is pluggable and some
rearchitecting was needed to support this.

Subject: [PATCH 0487/1429] netdevice zd1201: Convert directly reference of
 netdev->priv to netdev_priv()

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

(Original patch posted by Wang Chen <wangchen@cn.fujitsu.com> w/ above
changelog but using dev->ml_priv.  That doesn't seem appropriate
to me for this driver, so I've revamped it to use netdev_priv()
instead. -- JWL)

Subject: [PATCH 0489/1429] libertas: Fine grained configuration of
 wake-on-lan.

Based on a patch from Shailendra Govardhan <shailen@marvell.com>.
This patch allows implementation of more specific wake-on-lan rules than those
of ethtool.

Please note that only firmware 5.110.22.p20 and above supports this feature.

This patch only implements the driver/firmware interface, not the
userspace/driver interface.

Subject: [PATCH 0490/1429] ssb: struct device - replace bus_id with
 dev_name(), dev_set_name()

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

setting the FIF_OTHER_BSS flag as well.  Also explicitly call
ieee80211_configure_filter for mesh.

Subject: [PATCH 0495/1429] rt2x00: Fix LED state handling

For every global LED state change (register/unregister,
suspend/resume) we should force the LEDS to turn off.
This makes sure that the LEDS will always be in a sane
state after the state switch.

Note that when unregister is called but the LED class
wasn't resumed yet, we shouldn't change the LED state
since we might not have access to the device (device
was unplugged while suspended).

Also remove the checks in the activity, assoc and
radio LEDS which blocked calls to brightness_set()
when the state hasn't changed. Some of those LEDS
could be enabled by themselves when something happens
in the hardware (e.g. firmware is loaded). We already
did called rt2x00leds to switch the LED off, but those
calls were blocked.

Subject: [PATCH 0496/1429] rt2x00: Block set_key() during suspend/shutdown

mac80211 will call set_key() when the device is
shutting down. When the device is unplugged the
keys will be lost automatically due to the power
loss. When the device is not plugged but the module
is only unloaded the keys can remain in the device
hardware, when the module is loaded the keys will
be cleaned up during initialization.

This should prevent the problem reported by Johannes Berg,
where unplugging the device while suspended resulted in
a NULL pointer error during set_key() which was
caused because of the CSR base address being freed.

Subject: [PATCH 0497/1429] rt2x00: Fix BUG_ON() with antenna handling

With the new configuration handling, and more specifically
splitting the configuration of the antenna from the normal
configuration steps allowed a BUG_ON() to be triggered
in the driver because the SW_DIVERSITY was send to the
driver. This fixes that by catching the value early in
rt2x00config.c and replacing it with a sensible value.

This also fixes a problem where the antenna is not being
initialized at all when the radio is enabled. Since it
no longer is part of the mac80211 configuration the
only place where rt2x00 configured it was the SW diversity
handler. Obviously this is broken for all non-diversity
hardware and breaks SW diversity due to a broken initialization.

When the radio is enabled the antenna will be configured
once as soon as the config() callback function is called.

Subject: [PATCH 0498/1429] ath5k: ignore the return value of
 ath5k_hw_noise_floor_calibration

Noise floor calibration occasionally fails on Atheros hardware.
This is not fatal and can happen if there's simply too much
noise on the air. Ignoring the calibration error is the right
thing to do here, because when the error is ignored, the hardware
will still work, whereas if the error causes the driver to bail out
of a bigger configuration function and does not configure the tx
queues or the IMR (as is the case in reset.c), the hw no longer
works properly until the next reset.

On ARM alignment is done slightly different from other architectures.
struct ieee80211_tx_rate is aligned to word size, even though it only has 3
single-byte members, which triggers the BUILD_BUG_ON in
ieee80211_tx_info_clear_status

This patch marks the struct ieee80211_tx_rate as packed, so that ARM

Subject: [PATCH 0501/1429] ath5k: Fix IMR init

*On a previous patch i splitted AR5K_INT_TX to multiple different TX
interrupt flags for better handling but i forgot to unmask the new
TXDESC and TXEOL interrupts on ath5k_init and only left TXOK. However
for each queue we enable TXDESC and TXEOL interrupts, not TXOK so we don't
handle TX interrupts at all (because these interrupts remain masked on
PISR) and under load it results packet loss. Fix the problem by
unmasking TXDESC and TXEOL on ath5k_init.

I frequently run into this warning, and added some

As you can see, there are 6 bogus bytes (sometimes only five) and then
the frame. I don't know why, and I don't see how to recover, so let's
just drop these frames.

 ieee80211_notify_mac only reconnect BSS networks. Since IBSS does
 not need any auth or assoc steps we can just resume to the same
 condition before suspend. This patch will reestablish the ad-hoc
 network once it comes back from resume.

Subject: [PATCH 0510/1429] iwlwifi: don't fail power set when calibration is
 not done yet

This patch doesn't fail power save setting when calibration is
not done yet. The new power index is registered and will
be evaluated again anyway upon calibration completion.

This patch also eliminates WARN_ON in mac80211 hw_config during
initialization

Subject: [PATCH 0513/1429] iwlwifi: revamp tx scheduler byte count tables
 handling

This moves byte count tables to tx domain removing completely
ambivalent shared data. Changes handling of allocation
byte count tables and keep warm consistent memory
Moves general tx scheduler definitions from iwl-4956-hw.h
to iwl-fh.h

Subject: [PATCH 0519/1429] iwlwifi: use Rx single frame mode (one Rx frame per
 RB)

The RCSR default value for single frame mode is off (a RB contains more than
one frames). But the driver assumes single frame mode apparently. This patch
enables single frame mode for the hardware. It also adds a BUG_ON to make sure
the allocated skb satisfies the hardware alignment requirement and removes
a useless check.

Subject: [PATCH 0521/1429] rt2x00: Cleanup TX/RX entry handling

Merge the callback functions init_txentry() and
init_rxentry(). This makes life in rt2x00lib a
lot simpler and we can cleanup several functions.

rt2x00pci contained "fake" FIELD definitions for
descriptor words. This is not flexible since it
assumes the driver will always have the same field
to indicate if a driver is available or not.
This should be dependent on the driver, and we
should add a callback function for this.

This patch eliminates sparse warnings in pid rate scale algorithm
'debugfs: allow access to signed values' patch hit the dead end
year ago w/o much echo so I guess there is no real need to address this
properly.

Subject: [PATCH 0525/1429] rt2x00: Optimize get_duration / get_duration_res

We can optimize get_duration and get_duration_res
by making them a macro. They are really simple
calculation handlers so this doesn't matter much.

Often (especially in rt2400pci and rt2500pci,
the arguments are hardcoded, and the result value
is passed into other hardcoded values.

By making the functions a macro GCC can
optimize the entire thing much better.

Subject: [PATCH 0526/1429] rt2x00: Fix race condition when using inderect
 registers

Indirect registers require multiple calls to the CSR
register in order to access the indirect registers.
This must be protected under a lock to prevent race
conditions which could cause invalid data to
be returned when reading from the indirect register or silent
failures when writing data to the indirect register.

USB drivers where already protected under a mutex,
so rename the mutex and make PCI drivers use the mutex
as well.
This now means that BBP and RF registers are no longer
accessible in interrupt context. That is not a bad
situation since the slow behavior of accessing
those registers means we don't _want_ to access them
in interrupt context either.

Subject: [PATCH 0529/1429] lib80211: absorb crypto bits from net/ieee80211

These bits are shared already between ipw2x00 and hostap, and could
probably be shared both more cleanly and with other drivers.  This
commit simply relocates the code to lib80211 and adjusts the drivers
appropriately.

From: "John W. Linville" <linville@tuxdriver.com>

Subject: [PATCH 0532/1429] net/ieee80211 -> drivers/net/ipw2x00/libipw_*
 rename

The old ieee80211 code only remains as a support library for the ipw2100
and ipw2200 drivers.  So, move the code and rename it appropriately to
reflects it's true purpose and status.

 IEEE80211_CONF_SHORT_SLOT_TIME flag

This updates rtl8180 handling for short slot after "mac80211: fix short
slot handling". Only rtl8180_rtl8225 actually had code for handling
short slot times, so the other RF devices are untouched by this change.

Subject: [PATCH 0535/1429] MAINTAINERS: claim maintenance over rtl818x drivers

Michael and Andrea have moved-on, so we shouldn't be bothering them
about these drivers anymore.

Actually, Herton Ronaldo Krzesinski, Hin-Tak Leung, and Larry Finger
have been handling the rtl8187 stuff for a while.  So, I would welcome a
patch from one of them changing this to just RTL8180 and adding an
RTL8187 entry with their names...

Subject: [PATCH 0536/1429] wireless: clean up sysfs code using %pM

Remove converting the MAC address to a string by a direct byte
conversion and use %pM instead, since the code is now boilerplate
use a macro to define the show functions, and also use the shorter
__ATTR_RO macro to define the attributes.

As noted by John Linville, the RTL818X maintainers have "moved on", and the
responsibilities for RTL8180 and RTL8187 have been split. This is the
corresponding update of MAINTAINERS.

We can avoid some useless instructions if !CONFIG_NET_NS

Because of RCU, we use INET_MATCH or INET_TW_MATCH twice for the found
socket, so thats six instructions less per incoming TCP packet.

Yet another tbench speedup :)

 while going to D3

There has been an issue seen with the pci-e quad port adapters that will
cause them to generate a pci-e correctable error on some system while
transitioning to D3.

Since no action is needed on this correctable error the simplest solution
is to mask off the reporting of correctable errors.

Subject: [PATCH 0550/1429] e1000e: ESB2 config after link up

On ESB2, the MAC-to-PHY (Kumeran) interface must be configured after link
is up before any traffic is sent; a new PHY operations function pointer is
provided for this.  To facilitate read/write of the Kumeran registers
without blocking PHY register writes, the driver/firmware synchronization
method which previously used a hardware semaphore for both PHY and Kumeran
register accesses is now split.  New Kumeran register read/write functions
utilize this new synchronization method.

Subject: [PATCH 0551/1429] e1000e: link up/down messages must follow a
 specific format

The system log messages created on a link status change need to follow a
specific format to work with tools some customers use.

Subject: [PATCH 0554/1429] e1000e: store EEPROM version number to prevent
 unnecessary NVM reads

Rather than reading the NVM to get the EEPROM version number everytime the
ethool get_drvinfo function is called, read it once during probe and save
it for future reference.

Subject: [PATCH 0555/1429] e1000e: fix incorrect link status when switch
 module pulled

On 82571 with SerDes, the true link state is not always correct when read
from the STATUS register; use existing e1000_has_link() function instead.

Subject: [PATCH 0556/1429] e1000e: check return code from NVM accesses and fix
 bank detection

Check return code for all NVM accesses[1] and error out accordingly; log
a debug message for failed accesses.

For ICH8/9, the valid NVM bank detect function was not checking whether the
SEC1VAL (sector 1 valid) bit in the EECD register was itself valid (bits 8
and 9 also have to be set).  If invalid, it would have defaulted to the
possibly invalid bank 0.  Instead, try to use the valid bank detection
method used by ICH10 which has been cleaned up a bit.

[1] - reads and updates only; not writes because those are only writing to
the Shadow RAM, the update following the write is the only thing actually
writing the modified Shadow RAM contents to the NVM.

Subject: [PATCH 0558/1429] tg3: Use NET_IP_ALIGN

This patch replaces hardcoded 2's with the NET_IP_ALIGN constant or
TG3_RAW_IP_ALIGN where appropriate.  Some platforms can redefine the
NET_IP_ALIGN definition to zero if unaligned DMA transfers cost more
than the IP header alignment gains.  This patch represents a
performance improvement when using the 5701 on these platforms.
The copy path can be avoided.

TG3_RAW_IP_ALIGN is used in cases where we always want to align the
IP header on dword boundaries.

Per Dave Miller's suggestion, replace the remaining ioremap_nocache()
call with pci_ioremap_bar().  Remove the two IORESOURCE_MEM checks as
they are redundant.

Subject: [PATCH 0564/1429] tg3: Allow GPHY powerdown on 5761

The ENABLE_APE flag tells the driver whether or not the device has an
Application Processing Engine (APE).  The APE does not need the PHY to
be powered unless it is running management firmware.  For backwards
compatibility, management firmware will still set the ENABLE_ASF bit.
Consequently, there is no reason to consider the ENABLE_APE flag when
deciding whether or not to power down the phy.

-	The syncppp drivers in Linux provide a fairly complete 
-	implementation of Cisco HDLC and a minimal implementation of
-	PPP. The longer term goal is to switch the PPP layer to the
-	generic PPP interface that is new in Linux 2.3.x. The API should
-	remain unchanged when this is done, but support will then be
-	available for IPX, compression and other PPP features

Subject: [PATCH 0606/1429] enic: enable ethtool LRO support

Enable ethtool support for get/set_flags so LRO can be turned on/off
by fwding drivers such as the bridge driver.  LRO is not compatible
with fwding drivers.

Subject: [PATCH 0611/1429] igb: do not use phy ops in ethtool test cleanup for
 non-copper parts

Currently the igb driver is experiencing a panic due to a null function
pointer being used during the cleanup of the ethtool looback test on
fiber/serdes parts.  This patch prevents that and adds a check prior to
calling any phy function.

With this patch, TX/RX CCIDs can now be changed on a per-connection
basis, which overrides the defaults set by the global sysctl variables
for TX/RX CCIDs.

To make full use of this facility, the remaining patches of this patch
set are needed, which track dependencies and activate negotiated
feature values.

 supported by the endpoint (see include/linux/dccp.h for symbolic constants).
 The caller needs to provide a sufficiently large (> 2) array of type uint8_t.
 
+DCCP_SOCKOPT_CCID is write-only and sets both the TX and RX CCIDs at the same
+time, combining the operation of the next two socket options. This option is
+preferrable over the latter two, since often applications will use the same
+type of CCID for both directions; and mixed use of CCIDs is not currently well
+understood. This socket option takes as argument at least one uint8_t value, or
+an array of uint8_t values, which must match available CCIDS (see above). CCIDs
+must be registered on the socket before calling connect() or listen().
+
+DCCP_SOCKOPT_TX_CCID is read/write. It returns the current CCID (if set) or sets
+the preference list for the TX CCID, using the same format as DCCP_SOCKOPT_CCID.
+Please note that the getsockopt argument type here is `int', not uint8_t.
+
+DCCP_SOCKOPT_RX_CCID is analogous to DCCP_SOCKOPT_TX_CCID, but for the RX CCID.
+
 DCCP_SOCKOPT_SERVER_TIMEWAIT enables the server (listening socket) to hold
 timewait state when closing the connection (RFC 4340, 8.3). The usual case is
 that the closing server sends a CloseReq, whereupon the client holds timewait

Subject: [PATCH 0617/1429] dccp: API to query the current TX/RX CCID

This provides function to query the current TX/RX CCID dynamically,
without reliance on the minisock value, using dynamic information
available in the currently loaded CCID module.

This query function is then used to
 (a) provide the getsockopt part for getting/setting CCIDs via sockopts;
 (b) replace the current test for "which CCID is in use" in probe.c.

Subject: [PATCH 0618/1429] dccp: Increase the scope of variable-length
 htonl/ntohl functions

This extends the scope of two available functions,
encode|decode_value_var, to work up to 6 (8) bytes, to match maximum
requirements in the RFC.

These functions are going to be used both by general option processing
and feature negotiation code, hence declarations have been put into
feat.h.

Subject: [PATCH 0621/1429] net: Convert TCP/DCCP listening hash tables to use
 RCU

This is the last step to be able to perform full RCU lookups
in __inet_lookup() : After established/timewait tables, we
add RCU lookups to listening hash table.

The only trick here is that a socket of a given type (TCP ipv4,
TCP ipv6, ...) can now flight between two different tables
(established and listening) during a RCU grace period, so we
must use different 'nulls' end-of-chain values for two tables.

We define a large value :

#define LISTENING_NULLS_BASE (1U << 29)

So that slots in listening table are guaranteed to have different
end-of-chain values than slots in established table. A reader can
still detect it finished its lookup in the right chain.

Subject: [PATCH 0622/1429] net: fix tunnels in netns after ndo_ changes

dev_net_set() should be the very first thing after alloc_netdev().

"ndo_" changes turned simple assignment (which is OK to do before netns
assignment) into quite non-trivial operation (which is not OK, init_net was
used). This leads to incomplete initialisation of tunnel device in netns.

Subject: [PATCH 0623/1429] net: Make sure BHs are disabled in
 sock_prot_inuse_add()

The rule of calling sock_prot_inuse_add() is that BHs must
be disabled.  Some new calls were added where this was not
true and this tiggers warnings as reported by Ilpo.

Fix this by adding explicit BH disabling around those call sites.

Subject: [PATCH 0624/1429] axnet_cs: Fix build after net device ops ne2k
 conversion.

Commit 4e4fd4e485ad63a9074ff09a9b53ffc7a5c594ec ("ne2k: convert to
net_device_ops") exported some ei_* symbols from the 8390 library,
but the axnet_cs driver defines local static versions of the same
functions.

Rename them to avoid the namespace conflict.

Reported by Stephen Rothwell.

Subject: [PATCH 0625/1429] eth: Declare an optimized
 compare_ether_addr_64bits() function

Linus mentioned we could try to perform long word operations, even
on potentially unaligned addresses, on x86 at least. David mentioned
the HAVE_EFFICIENT_UNALIGNED_ACCESS test to handle this on all
arches that have efficient unailgned accesses.

I tried this idea and got nice assembly on 32 bits:

158:   33 82 38 01 00 00       xor    0x138(%edx),%eax
15e:   33 8a 34 01 00 00       xor    0x134(%edx),%ecx
164:   c1 e0 10                shl    $0x10,%eax
167:   09 c1                   or     %eax,%ecx
169:   74 0b                   je     176 <eth_type_trans+0x87>

And very nice assembly on 64 bits of course (one xor, one shl)

Nice oprofile improvement in eth_type_trans(), 0.17 % instead of 0.41 %,
expected since we remove 8 instructions on a fast path.

This patch implements a compare_ether_addr_64bits() function, that
uses the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS ifdef to efficiently
perform the 6 bytes comparison on all capable arches.

Subject: [PATCH 0626/1429] net: Make sure BHs are disabled in
 sock_prot_inuse_add()

The rule of calling sock_prot_inuse_add() is that BHs must
be disabled.  Some new calls were added where this was not
true and this tiggers warnings as reported by Ilpo.

Fix this by adding explicit BH disabling around those call sites,
or moving sock_prot_inuse_add() call inside an existing BH disabled
section.

 warning

net/netfilter/nf_conntrack_proto_sctp.c: In function 'sctp_packet':
net/netfilter/nf_conntrack_proto_sctp.c:376: warning: array subscript is above array bounds

gcc doesn't realize that do_basic_checks() guarantees that there is
at least one valid chunk and thus new_state is never SCTP_CONNTRACK_MAX
after the loop. Initialize to SCTP_CONNTRACK_NONE to avoid the warning.

Subject: [PATCH 0635/1429] infiniband: Kill directly reference of netdev->priv

This use of netdev->priv is wrong.
The right way is:
alloc_netdev() with no memory for private data.
make netdev->ml_priv to point to c2_dev.

Subject: [PATCH 0636/1429] pkt_sched: sch_drr: fix drr_dequeue loop()

Jarek Poplawski points out:

If all child qdiscs of sch_drr are non-work-conserving (e.g. sch_tbf)
drr_dequeue() will busy-loop waiting for skbs instead of leaving the
job for a watchdog. Checking for list_empty() in each loop isn't
necessary either, because this can never be true except the first time.

Using non-work-conserving qdiscs as children of DRR makes no sense,
simply bail out in that case.

so similarly to Jamal's hashing idea IIRC. (Looking for next hits could
be still optimized, but it's really fast as it is.)

Subject: [PATCH 0638/1429] net: avoid a pair of dst_hold()/dst_release() in
 ip_append_data()

We can reduce pressure on dst entry refcount that slowdown UDP transmit
path on SMP machines. This pressure is visible on RTP servers when
delivering content to mediagateways, especially big ones, handling
thousand of streams. Several cpus send UDP frames to the same
destination, hence use the same dst entry.

This patch makes ip_append_data() eventually steal the refcount its
callers had to take on the dst entry.

This doesnt avoid all refcounting, but still gives speedups on SMP,
on UDP/RAW transmit path

Subject: [PATCH 0640/1429] tcp: collapse more than two on retransmission
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I always had thought that collapsing up to two at a time was
intentional decision to avoid excessive processing if 1 byte
sized skbs are to be combined for a full mtu, and consecutive
retransmissions would make the size of the retransmittee
double each round anyway, but some recent discussion made me
to understand that was not the case. Thus make collapse work
more and wait less.

It would be possible to take advantage of the shifting
machinery (added in the later patch) in the case of paged
data but that can be implemented on top of this change.

tcp_skb_is_last check is now provided by the loop.

I tested a bit (ss-after-idle-off, fill 4096x4096B xfer,
10s sleep + 4096 x 1byte writes while dropping them for
some a while with netem):

I knew already when rewriting the sacktag that this condition
was too conservative, change it now since it prevent lot of
useless work (especially in the sack shifter decision code
that is being added by a later patch). This shouldn't change
anything really, just save some processing regardless of the
shifter.

This is preparatory work for SACK combiner patch which may

because it will intentionally avoids splitting skb to SACKed
and not sacked parts.

Subject: [PATCH 0645/1429] tcp: Try to restore large SKBs while SACK
 processing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During SACK processing, most of the benefits of TSO are eaten by
the SACK blocks that one-by-one fragment SKBs to MSS sized chunks.
Then we're in problems when cleanup work for them has to be done
when a large cumulative ACK comes. Try to return back to pre-split
state already while more and more SACK info gets discovered by
combining newly discovered SACK areas with the previous skb if
that's SACKed as well.

This approach has a number of benefits:

1) The processing overhead is spread more equally over the RTT
2) Write queue has less skbs to process (affect everything
   which has to walk in the queue past the sacked areas)
3) Write queue is consistent whole the time, so no other parts
   of TCP has to be aware of this (this was not the case with
   some other approach that was, well, quite intrusive all
   around).
4) Clean_rtx_queue can release most of the pages using single
   put_page instead of previous PAGE_SIZE/mss+1 calls

In case a hole is fully filled by the new SACK block, we attempt
to combine the next skb too which allows construction of skbs
that are even larger than what tso split them to and it handles
hole per on every nth patterns that often occur during slow start
overshoot pretty nicely. Though this to be really useful also
a retransmission would have to get lost since cumulative ACKs
advance one hole at a time in the most typical case.

TODO: handle upwards only merging. That should be rather easy
when segment is fully sacked but I'm leaving that as future
work item (it won't make very large difference anyway since
this current approach already covers quite a lot of normal
cases).

I was earlier thinking of some sophisticated way of tracking
timestamps of the first and the last segment but later on
realized that it won't be that necessary at all to store the
timestamp of the last segment. The cases that can occur are
basically either:
  1) ambiguous => no sensible measurement can be taken anyway
  2) non-ambiguous is due to reordering => having the timestamp
     of the last segment there is just skewing things more off
     than does some good since the ack got triggered by one of
     the holes (besides some substle issues that would make
     determining right hole/skb even harder problem). Anyway,
     it has nothing to do with this change then.

I choose to route some abnormal looking cases with goto noop,
some could be handled differently (eg., by stopping the
walking at that skb but again). In general, they either
shouldn't happen at all or are rare enough to make no difference
in practice.

In theory this change (as whole) could cause some macroscale
regression (global) because of cache misses that are taken over
the round-trip time but it gets very likely better because of much
less (local) cache misses per other write queue walkers and the
big recovery clearing cumulative ack.

Worth to note that these benefits would be very easy to get also
without TSO/GSO being on as long as the data is in pages so that
we can merge them. Currently I won't let that happen because
DSACK splitting at fragment that would mess up pcounts due to
sk_can_gso in tcp_set_skb_tso_segs. Once DSACKs fragments gets
avoided, we have some conditions that can be made less strict.

TODO: I will probably have to convert the excessive pointer
passing to struct sacktag_state... :-)

My testing revealed that considerable amount of skbs couldn't
be shifted because they were cloned (most likely still awaiting
tx reclaim)...

[The rest is considering future work instead since I got
repeatably EFAULT to tcpdump's recvfrom when I added
pskb_expand_head to deal with clones, so I separated that
into another, later patch]

...To counter that, I gave up on the fifth advantage:

5) When growing previous SACK block, less allocs for new skbs
   are done, basically a new alloc is needed only when new hole
   is detected and when the previous skb runs out of frags space

...which now only happens of if reclaim is fast enough to dispose
the clone before the SACK block comes in (the window is RTT long),
otherwise we'll have to alloc some.

With clones being handled I got these numbers (will be somewhat
worse without that), taken with fine-grained mibs:

                  TCPSackShifted 398
                   TCPSackMerged 877

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The earlier version was just very basic one which is "playing
safe" by always clearing the hints. However, clearing of a hint
is extremely costly operation with large windows, so it must be
avoided at all cost whenever possible, there is a way with
shifting too achieve not-clearing.

Subject: [PATCH 0648/1429] tcp: handle shift/merge of cloned skbs too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This caused me to get repeatably:

  tcpdump: pcap_loop: recvfrom: Bad address

Happens occassionally when I tcpdump my for-looped test xfers:
  while [ : ]; do echo -n "$(date '+%s.%N') "; ./sendfile; sleep 20; done

Rest of the relevant commands:
  ethtool -K eth0 tso off
  tc qdisc add dev eth0 root netem drop 4%
  tcpdump -n -s0 -i eth0 -w sacklog.all

Running net-next under kvm, connection goes to the same host
(basically just out of kvm). The connection itself works ok
and data gets sent without corruption even with a large
number of tests while tcpdump fails usually within less than
5 tests.

Whether it only happens because of this change or not, I
don't know for sure but it's the only thing with which
I've seen that error. The non-cloned variant works w/o it
for much longer time. I'm yet to debug where the error
actually comes from.

coding ifdef against kernel version.

Subject: [PATCH 0651/1429] hso: Fix crashes on close.

Moved serial_open_count in hso_serial_open to
prevent crashes owing to the serial structure being made NULL
when hso_serial_close is called even though hso_serial_open
returned -ENODEV, Alan Cox pointed out this happens,
also put in sanity check in hso_serial_close
to check for a valid serial structure which should prevent
the most reproducable crash in the driver when the hso device
is disconnected while in use.

Subject: [PATCH 0653/1429] hso: Fix free of mutexes still in use.

A new structure hso_mutex_table had to be declared statically
& used as as hso_device mutex_lock(&serial->parent->mutex) etc
is freed in hso_serial_open & hso_serial_close by kref_put while
the mutex is still in use.

This is a substantial change but should make the driver much stabler.

Subject: [PATCH 0655/1429] hso: Hook up ->reset_resume

Made usb_drivers reset_resume function point to hso_resume this
fixes problems a usb reset is done when the network interface
is left idle for a few minutes. Possibly reset_resume should
initialise hardware more but this works in the common case.

Subject: [PATCH 0657/1429] DCB: fix kconfig option

Since the netlink option for DCB is necessary to actually be useful,
simplified the Kconfig option.  In addition, added useful help text for the
Kconfig option.

There is a reference to a Buffer Size extention bit that is unneded by
82575/82576 hardware.  Since it is not needed it should be removed from the

Subject: [PATCH 0662/1429] netfilter: nfmark routing in OUTPUT, mangle,
 NFQUEUE

This patch let nfmark to be evaluated for routing decision for OUTPUT
packet, in mangle table, when process paquet in NFQUEUE
Until now, only change (in NFQUEUE process) on fields src_addr,
dest_addr and tos could make netfilter to reevalute the routing.

Subject: [PATCH 0670/1429] rt2x00: Cleanup indirect register access

All code which accessed indirect registers was similar
in respect to the for-loop, the given timeout, etc.
Move it into a seperate function, which for PCI drivers
can be moved into rt2x00pci.

This allows us to cleanup the cleanup the code further
by removing the goto statementsand making the codepath
look a bit nicer.

Subject: [PATCH 0671/1429] rt2x00: Move rt73usb register access wrappers into
 rt2x00usb

rt2500usb and rt73usb have different register word sizes,
for that reason the register access wrappers were never
moved into rt2x00usb.
With rt2800usb on its way, we should favor the 32bit
register access and move those wrappers into rt2x00usb.
That saves duplicate code, since only rt2500usb will
need the special 16bit wrappers.

Subject: [PATCH 0672/1429] rt2x00: Fix TX failure path

The callback function write_tx_data() can only fail
when our ENTRY_OWNER_DEVICE_DATA flag on a queue entry
failed to determine the entry was not available and
it is in fact still owned by the hardware.
This means that if that function fails the queue
must be stopped in mac80211.

When rt2x00queue_get_queue() returns NULL in the TX
path, it means mac80211 has passed us an invalid queue,
although this should be impossible, it shouldn't hurt
if we send mac80211 a signal to stop the queue either.

Both issues can simply be resolved by removing their
manual failure handler and making them use the failure path
provided in rt2x00mac_tx().

Subject: [PATCH 0675/1429] iwlwifi: rs: remove fc variable and other cleanups

This patch
1. Removes use once use only fc variables, they are useless after refactoring
ieee80211 frame control handlers
2. Other trivial cleanups

Subject: [PATCH 0678/1429] iwlwifi: configure_filter rewrite

The patch rewrites the mac80211 configure_filter handler to better mapping
mac80211 filter flags to iwlwifi hardware filter flags. We now can support
5 mac80211 filter flags: FIF_OTHER_BSS, FIF_ALLMULTI, FIF_PROMISC_IN_BSS,
FIF_BCN_PRBRESP_PROMISC and FIF_CONTROL. This patch also avoids reconnecting
if the filter flags are changed when the STA is associated. Because rx_assoc
is used when full rxon is not necessary.

account for unexpected REGDOM_SET_BY_*'s, lets just remove
the switch statement as this code does not change and
won't change even when we add 802.11d support.

This patch has no functional changes.

Subject: [PATCH 0684/1429] cfg80211: separate intersection section in
 __set_regdom()

So far the __set_regdom() code is pretty generic as the
intersection case is fairly straight forward; this will however
change when 802.11d support is added so lets separate intersection
code for now in preparation for 802.11d support.

This patch only has slight functional changes.

Subject: [PATCH 0686/1429] cfg80211: call_crda() won't tell us if CRDA was
 present

kobject_uevent_env() can return an error but it just tells us
if the uvent was built/sent or not, it doesn't tell us anything
about what happened in userspace, whether the udev rule was present
nor does it tell us if CRDA was present or not. So remove
the informative complaint about it assuming it will tell us
such things.

Note that you can determine if CRDA is present after loading cfg80211
by using:

is_old_static_regdom(cfg80211_regdomain)

but this doesn't account for possible user install after initial
boot, and also for when the user uses the static EU regulatory
domain.

Subject: [PATCH 0688/1429] cfg80211/mac80211: Add 802.11d support

This adds country IE parsing to mac80211 and enables its usage
within the new regulatory infrastructure in cfg80211. We parse
the country IEs only on management beacons for the BSSID you are
associated to and disregard the IEs when the country and environment
(indoor, outdoor, any) matches the already processed country IE.

To avoid following misinformed or outdated APs we build and use
a regulatory domain out of the intersection between what the AP
provides us on the country IE and what CRDA is aware is allowed
on the same country.

A secondary device is allowed to follow only the same country IE
as it make no sense for two devices on a system to be in two
different countries.

In the case the AP is using country IEs for an incorrect country
the user may help compliance further by setting the regulatory
domain before or after the IE is parsed and in that case another
intersection will be performed.

CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA
present.

Subject: [PATCH 0689/1429] cfg80211: add support for custom firmware
 regulatory solutions

This adds API to cfg80211 to allow wireless drivers to inform
us if their firmware can handle regulatory considerations *and*
they cannot map these regulatory domains to an ISO / IEC 3166
alpha2. In these cases we skip the first regulatory hint instead
of expecting the driver to build their own regulatory structure,
providing us with an alpha2, or using the reg_notifier().

Subject: [PATCH 0690/1429] iwlwifi: enable custom fw regulatory solution

This enables the custom firmware regulatory solution option
on iwlwifi drivers. These devices are uncapable of mapping their
EEPROM regulatory domain to a specific ISO / IEC alpha2.
Although the new 11n devices (>= iwl 5000) have only
3 regultaory SKUs -- MOW, ABG (no N) and BG -- the older
devices (3945 and 4965) have a more complex SKU arrangement
and therefore its not practical to move this to the driver.

Subject: [PATCH 0693/1429] ath9k: Build RFKILL feature even when RFKILL
 subsystem is a MODULE

Currently, ath9k builds RFKILL feature only when the RFKILL subsystem
is built part of the kernel. Build RFKILL feature regardless of whether
RFKILL subsystem is built as a MODULE or part of the kernel.

Subject: [PATCH 0695/1429] ath9k: Race condition in accessing TX and RX
 buffers.

Race condition causes RX buffers to be accessed even before it is
initialized. The RX and TX buffers are initialized immediately after
the hardware is registered with mac80211. The mac80211 start callback
is ready to be fired once the device is registered for a case when the
wpa_supplicant is also running at the same time.

The same race condition is also possible for RKFILL registration
as RFKILL init happens after the device registration with mac80211
and it is possible that rfkill_register would be called even before
it is initialized.

Subject: [PATCH 0696/1429] rtl8187: fix 8187B throughput regression

Hin-Tak Leung reported that after the change "rtl8187: add short slot
handling for 8187B" his RTL8187B started to give low throughput on
network transfers. Turns out that the SIFS setting used isn't ok, it
doesn't look to be the real aSIFSTime, using the "magical" 0x22 value
like on other 818x variants as the vendor does too fixes the issue.

Subject: [PATCH 0698/1429] rtl8187: feedback transmitted packets using tx
 close descriptor for 8187B

Realtek 8187B has a receive command queue to feedback beacon interrupt
and transmitted packet status. Use it to feedback mac80211 about status
of transmitted packets. Unfortunately in the course of testing I found
that the sequence number reported by hardware includes entire sequence
control in a 12 bit only field, so a workaround is done to check only
lowest bits.

Subject: [PATCH 0699/1429] rtl8187: Remove module warning and dependence on
 CONFIG_EXPERIMENTAL

After considerable testing, the initial fears that the driver might damage
some flavors of RTL8187B hardware seem to be groundless. Accordingly, the
logged warning is removed. In addition, Kconfig is changed to remove the
dependence on EXPERIMENTAL.

Instead of hardcoding the used in/out endpoints
we should detect them by walking through all
available endpoints.

rt2800usb will gain the most out of this, because
the legacy drivers indicate that there are multiple
endpoints available.
However this code might benefit at least rt73usb as
well for the MIMO queues, and if we are really lucky
rt2500usb will benefit because for the TX and PRIO
queues.

Even if rt2500usb and rt73usb do not get better performance
after this patch, the endpoint detection still belongs to
rt2x00usb, and it shouldn't hurt to always try to detect
the available endpoints.

Make the DMAable mameory consistent with pci_set_consistent_dma_mask().
The DMA-mapping.txt Documentation recommends this but for PCI-X
considerations and on strange architecture like SGI SN2, not sure
why it would fix an issue but lets see if it does, just in case.

Before this, this driver was tested with x86_64 with about
7 GB of RAM, not sure if this is really needed.

Subject: [PATCH 0709/1429] mac80211: don't assume driver has been attached on
 registration

mac80211's ieee80211_register_hw() is often called within the
probe path so it cannot assume the device's driver structure
has been attached yet so to create a workqueue instead of
using driver->name use the wiphy's phy%d name. The name doesn't
really matter anyway.

This should fix sporadic oopses found when we race to beat the
driver pointer setting. Not even sure how this was working properly.

prot->destroy is not called with BH disabled. So we must add
explicit BH disable around call to sock_prot_inuse_add()
in sctp_destroy_sock()

Subject: [PATCH 0712/1429] net: udp_unhash() can test if sk is hashed

Impact: Optimization

Like done in inet_unhash(), we can avoid taking a chain lock if
socket is not hashed in udp_unhash()

Triggered by close(socket(AF_INET, SOCK_DGRAM, 0));

Subject: [PATCH 0717/1429] netns: filter out uevent not belonging to init_net

This patch will filter out the uevent not related to the init_net.
Without this patch if a network device is created in a network
namespace with the same name as one network device belonging to the
initial network namespace (eg. eth0), when the network namespace
will die and the network device will be destroyed, an event will
be sent and catched by the udevd daemon. That will result to have
the real network device to be shutdown because the udevd/uevent are
not namespace aware.

this warning:

  drivers/net/mlx4/en_rx.c: In function ‘mlx4_en_activate_rx_rings’:
  drivers/net/mlx4/en_rx.c:412: warning: ‘err’ may be used uninitialized in this function

Triggers because 'err' is uninitialized in the following input
conditions: priv->rx_ring_num is zero and mlx4_en_fill_rx_buffers()
fails.

But even if ->rx_ring_num is nonzero, 'err' will be zero if
mlx4_en_fill_rx_buffers() fails and mlx4_en_activate_rx_rings() returns
success - incorrectly.

So it's best to keep the error code uptodate on mlx4_en_fill_rx_buffers()
calls as well.

this warning:

is a bogus GCC warning. The compiler does not recognize the relation
between "value" and "mandatory" variables: the code flow can ever reach
the "out_invalid_option:" label if 'mandatory' is set to 1, and when
'mandatory' is non-zero, we'll always have 'value' initialized.

Help out the compiler by annotating the variable.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

fix this warning:

  net/bluetooth/rfcomm/sock.c: In function ‘rfcomm_sock_ioctl’:
  net/bluetooth/rfcomm/sock.c:795: warning: unused variable ‘sk’

perhaps BT_DEBUG() should be improved to do printf format checking
instead of the #ifdef, but that looks quite intrusive: each bluetooth
.c file undefines the macro.

Subject: [PATCH 0737/1429] atlx: fix warning in drivers/net/atlx/atl2.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fix this warning:

  drivers/net/atlx/atl2.c: In function ‘atl2_request_irq’:
  drivers/net/atlx/atl2.c:644: warning: unused variable ‘err’

'err' is unused in the !CONFIG_PCI_MSI case.

Instead of further increasing the #ifdeffery in this function,
restructure the code a bit and get rid of the #ifdef. This
relies on the fact that pci_enable_msi() will always fail in
the !CONFIG_PCI_MSI case.

There should be no change in driver behavior.

fix warning:

this seems to be a real bug - depca_eisa_probe() does not check
for failure. Add it, symmetric to depca_isa_probe().

Subject: [PATCH 0743/1429] netns xfrm: per-netns xfrm_state_all list

This is done to get
a) simple "something leaked" check
b) cover possible DoSes when other netns puts many, many xfrm_states
   onto a list.
c) not miss "alien xfrm_state" check in some of list iterators in future.

Subject: [PATCH 0750/1429] netns xfrm: per-netns state GC list

km_waitq is going to be made per-netns to disallow spurious wakeups
in __xfrm_lookup().

To not wakeup after every garbage-collected xfrm_state (which potentially
can be from different netns) make state GC list per-netns.

Subject: [PATCH 0753/1429] netns xfrm: add struct xfrm_policy::xp_net

Again, to avoid complications with passing netns when not necessary.
Again, ->xp_net is set-once field, once set it never changes.

Subject: [PATCH 0773/1429] netns xfrm: lookup in netns

Pass netns to xfrm_lookup()/__xfrm_lookup(). For that pass netns
to flow_cache_lookup() and resolver callback.

Take it from socket or netdevice. Stub DECnet to init_net.

Subject: [PATCH 0780/1429] netns xfrm: xfrm_user module in netns

Grab netns either from netlink socket, state or policy.

SA and SPD flush are in init_net for now, this requires little
attention, see below.

Subject: [PATCH 0792/1429] netns xfrm: per-netns sysctls

Make
	net.core.xfrm_aevent_etime
	net.core.xfrm_acq_expires
	net.core.xfrm_aevent_rseqth
	net.core.xfrm_larval_drop

sysctls per-netns.

For that make net_core_path[] global, register it to prevent two
/proc/net/core antries and change initcall position -- xfrm_init() is called
from fs_initcall, so this one should be fs_initcall at least.

Subject: [PATCH 0793/1429] 8390: add common net_device ops

Fix the defactoring of ei_XXX functions in 8390 and 8390p.
Remove the tx_timeout hack since no driver including the 3c503
overrides tx_timeout at this time, looks like a legacy thing.

Also, since several drivers all have same hooks, provide common
netdev_ops.

Subject: [PATCH 0809/1429] tc: policing requires a rate estimator

Found that while trying average rate policing, it was possible to
request average rate policing without a rate estimator. This results
in no policing which is harmless but incorrect.

Since policing could be setup in two steps, need to check
in the kernel.

Subject: [PATCH 0810/1429] net: Use a percpu_counter for sockets_allocated

Instead of using one atomic_t per protocol, use a percpu_counter
for "sockets_allocated", to reduce cache line contention on
heavy duty network servers.

Note : We revert commit (248969ae31e1b3276fc4399d67ce29a5d81e6fd9
net: af_unix can make unix_nr_socks visbile in /proc),
since it is not anymore used after sock_prot_inuse_add() addition

Subject: [PATCH 0812/1429] net: release skb->dst in sock_queue_rcv_skb()

When queuing a skb to sk->sk_receive_queue, we can release its dst,
not anymore needed.  Since current cpu did the dst_hold(), refcount is
probably still hot int this cpu caches.

This avoids readers to access the original dst to decrement its
refcount, possibly a long time after packet reception. This should
speedup UDP and RAW receive path.

Subject: [PATCH 0826/1429] ath9k: Revamp RX handling

Remove a lot of old, crufty code and make
RX status reporting a bit sane and clean.

Do not do anything to the RX skb before unmapping.
So in ath_rx_tasklet(), move the skb_put() after PCI unmap.

Subject: [PATCH 0829/1429] ath9k: Remove ath_rate_softc

Move the hw rate tables to ath_softc, and access them directly.
tx_triglevel_max is global, move it to ath_rate_node.
Now that ath_rate_softc is gone, rate control attach becomes simpler.

From a8efee4f4740c61fccaf73608df282c4ee24ae86 Mon Sep 17 00:00:00 2001
From: Sujith <Sujith.Manoharan@atheros.com>
Date: Tue, 18 Nov 2008 09:07:30 +0530
Subject: [PATCH 0830/1429] ath9k: Use rate_driver_data

Remove the hack using vif, and use rate_driver_data within
skb->cb to hold driver specific rate information.
Setup the rate series in the skb's tx control area and remove
all references to ath9k specific rate series ( using struct ath_rc_series ).

Subject: [PATCH 0831/1429] ath9k: Remove ath9k_rate_table

Maintaining two sets of rate tables is redundant, remove one
and use struct ath_rate_table exclusively.

Subject: [PATCH 0832/1429] ath9k: General code scrub

Replace TRUE/FALSE macros with VALID/INVALID macros.
Follow a consistent variable convention.
Remove unnecessary comments.
Add all RC phy macros into a single enum.
Merge functions into reasonably sized entities.

- * Interface definitions for transmit rate control modules for the
- * Atheros driver.
- *
- * A rate control module is responsible for choosing the transmit rate
- * for each data frame.  Management+control frames are always sent at
- * a fixed rate.
- *
- * Only one module may be present at a time; the driver references
- * rate control interfaces by symbol name.  If multiple modules are
- * to be supported we'll need to switch to a registration-based scheme
- * as is currently done, for example, for authentication modules.
- *
- * An instance of the rate control module is attached to each device
- * at attach time and detached when the device is destroyed.  The module
- * may associate data with each device and each node (station).  Both
- * sets of storage are opaque except for the size of the per-node storage
- * which must be provided when the module is attached.
- *
- * The rate control module is notified for each state transition and
- * station association/reassociation.  Otherwise it is queried for a
- * rate for each outgoing frame and provided status from each transmitted
- * frame.  Any ancillary processing is the responsibility of the module
- * (e.g. if periodic processing is required then the module should setup
- * it's own timer).
- *
- * In addition to the transmit rate for each frame the module must also
- * indicate the number of attempts to make at the specified rate.  If this
- * number is != ATH_TXMAXTRY then an additional callback is made to setup
- * additional transmit state.  The rate control code is assumed to write
- * this additional data directly to the transmit descriptor.

Subject: [PATCH 0835/1429] ath9k: Fix bug in deciphering channel flags

CHANNEL_CCK flag is set for all 2 Ghz channels, so IS_CHAN_CCK() would
turn out to be true for all channles in that band.
Use IS_CHAN_B() now, which checks the channel mode and not the channel
flags.

Subject: [PATCH 0838/1429] ath5k: set mac address in add_interface

Configure the mac address in add_interface and clear it in
remove_interface so that users can change the mac address
to something other than the one in the eeprom.  Also avoid
setting it at attach time so that we won't ack packets
until fully set up.

Subject: [PATCH 0839/1429] iwl3945 : Fix ad-hoc mode for 3945

Patch fixes the ad-hoc mode by
1) Removing redundant clear_stations_table which prevented generation of
beacons.
2) Setting assoc_id to 1. It was never set so preventing tx flow
in iwl3945_tx_skb.

When a disassoc packet is received from the AP with a reason code of
'leaving the BSS', mac80211 should go into DISABLED state just as it
would do if the AP suddenly went away for some reason, as that is what
will happen shortly after the AP leaves anyway.

Subject: [PATCH 0849/1429] rfkill: preserve state across suspend

The rfkill class API requires that the driver connected to a class
call rfkill_force_state() on resume to update the real state of the
rfkill controller, OR that it provides a get_state() hook.

This means there is potentially a hidden call in the resume code flow
that changes rfkill->state (i.e. rfkill_force_state()), so the
previous state of the transmitter was being lost.

The simplest and most future-proof way to fix this is to explicitly
store the pre-sleep state on the rfkill structure, and restore from
that on resume.

Subject: [PATCH 0850/1429] rfkill: always call get_state() hook on resume

We "optimize" away the get_state() hook call on rfkill_toggle_radio
when doing a forced state change.  This means the resume path is not
calling get_state() as it should.

Call it manually on the resume handler, as we don't want to mess with
the EPO path by removing the optimization.  This has the added benefit
of making it explicit that rfkill->state could have been modified
before we hit the rfkill_toggle_radio() call in the class resume
handler.

Subject: [PATCH 0851/1429] ath9k: Handle -ENOMEM on RX gracefully

We would get an oops on RX on -ENOMEM by passing
NULL to the hardware on ath_rx_buf_link(). The oops
would look something like this:

ath_rx_tasklet+0x515/0x53b
ath9k_tasklet+0x48
tasklet_action
__do_softirq
irq_exit
do_IRQ

RIP: ath_rx_buf_link+0x3a

We correct this by handling the requeue directly on
the ath_rx_tasklet() and trying to allocate an skb
*prior* to sending up the last hardware processed
skb. If we run out of memory this gauranteees we have
skbs to work with while it simply drops new received
frames.

Subject: [PATCH 0854/1429] orinoco: Resume spectrum_cs in the same way as
 orinoco_cs

Retrieval of external firmware has been resolved, and should work with
the standard orinoco resume algorithm.

This fixes an issue where priv->hw_unavailable indicates the card is
ready when firmware has not been loaded.

Subject: [PATCH 0855/1429] orinoco: Provide option to avoid unnecessary fw
 caching

Make firmware caching on startup optional, and make it default.

When the option is not selected and PM_SLEEP is configured, then
cache firmware in the suspend pm_notifier. This configuration saves
about 64k RAM in normal use, but can lead to a situation where the
driver is configured to use a different firmware.

Subject: [PATCH 0856/1429] nl80211: Change max TX power to be in mBm instead
 of dBm

In order to be consistent with NL80211_ATTR_POWER_RULE_MAX_EIRP,
change NL80211_FREQUENCY_ATTR_MAX_TX_POWER to use mBm and U32 instead
of dBm and U8. This is a userspace interface change, but the previous
version had not yet been pushed upstream and there are no userspace
programs using this yet, so there is justification to get this change in
as long as it goes in before the previous version gets out.

Subject: [PATCH 0858/1429] ath9k: Use proper TX channel width for setting
 channels

The TX channel width of the BSS can be obtained only after association.
In all cases, default to HT20 if HT is enabled, and set
chan width to HT40 only if the BSS supports it.

Subject: [PATCH 0859/1429] p54: fix wmm queue settings

This patch fixes a regression (introduced by
"p54: more definitions form lmac_longbow.h and pda.h")

It turned out that the "ret" variable wasn't initialized and
this caused the following warnings/errors to appear:

wmaster1: failed to set TX queue parameters for queue 2
wmaster1: failed to set TX queue parameters for queue 3
wmaster1: failed to set TX queue parameters for queue 1
wmaster1: failed to set TX queue parameters for queue 0

Subject: [PATCH 0862/1429] pkt_sched: gen_estimator: Optimize
 gen_estimator_active()

Since all other gen_estimator functions use bstats and rate_est params
together, and searching for them is optimized now, let's use this also
in gen_estimator_active(). The return type of gen_estimator_active()
is changed to bool, and gen_find_node() parameters to const, btw.

In tcf_act_police_locate() a check for ACT_P_CREATED is added before
calling gen_estimator_active().

Subject: [PATCH 0877/1429] netlink: allow empty nested attributes

validate_nla() currently doesn't allow empty nested attributes. This
makes userspace code unnecessarily complicated when starting and ending
the nested attribute is done by generic upper level code and the inner
attributes are dumped by a module.

Add a special case to accept empty nested attributes. When the nested
attribute is non empty, the same checks as before are performed.

Subject: [PATCH 0883/1429] phy: power management support

This patch adds the power management support into the physical
abstraction layer.

Suspend and resume functions respectively turns on/off the bit 11
into the PHY Basic mode control register.
Generic PHY device starts supporting PM.

In order to support the wake-on LAN and avoid to put in power down
the PHY device, the MDIO is aware of what the Ethernet device wants to do.

Voluntary, no CONFIG_PM defines were added into the sources.
Also generic suspend/resume functions are exported to allow
other drivers use them (such as genphy_config_aneg etc.).

Within the phy_driver_register function, we need to remove the
memset. It overrides the device driver owner and it is not good.

Subject: [PATCH 0886/1429] cxgb3: Fix sparse warning and micro-optimize
 is_pure_response()

The function is_pure_response() does "ntohl(var) & const" and then
essentially just tests whether the result is 0 or not; this can be done
more efficiently by computing "var & htonl(const)" instead and doing the
byte swap at compile time instead of run time.

This change slightly shrinks the compiled code; eg on x86-64 we save a
couple of bswapl instructions:

add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-8 (-8)
function                                     old     new   delta
t3_sge_intr_msix_napi                        544     536      -8

and this also has the pleasant side effect of fixing a sparse warning:

The N_GIGASET_M101 line discipline implemented by the ser_gigaset
driver does not transfer any data from/to userspace through the
tty interface. Therefore a poll method is not needed.

Subject: [PATCH 0889/1429] Bluetooth: Add fine grained mem_flags usage to
 btusb driver

The URB submission routines need more fine grained control for the
mem_flags used by kmalloc(), usb_alloc_urb() and usb_submit_urb() to
better support different caller situations. Add a mem_flags parameter
and give the caller full control.

Subject: [PATCH 0890/1429] Bluetooth: Handle bulk URBs in btusb driver from
 notify callback

With the addition of usb_unlink_anchored_urbs() it is possible to fully
control the bulk URBs from the notify callback. There is no need to
schedule work and so only do this for the ISOC URBs.

During suspend it is important that all URBs are cancelled and then on
resume re-submitted. This gives initial suspend/resume support.

            struct hci_dev_req dev_req[0];  /* hci_dev_req structures */
    };

sizeof(struct hci_dev_list_req) == 4, so the two bytes immediately
following "dev_num" will never be initialized. When this structure
is copied to userspace, these uninitialized bytes are leaked.

Fix by using kzalloc() instead of kmalloc(). Found using kmemcheck.

 bt_slock_key_strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After adding proper lockdep annotations for Bluetooth protocols the case
when lockdep is disabled produced two compiler warnings:

net/bluetooth/af_bluetooth.c:60: warning: ‘bt_key_strings’ defined but not used
net/bluetooth/af_bluetooth.c:71: warning: ‘bt_slock_key_strings’ defined but not used

Fix both of them by adding a CONFIG_DEBUG_LOCK_ALLOC conditional around
them and re-arranging the code a little bit.

Subject: [PATCH 0895/1429] Bluetooth: Change simple_strtol to simple_strtoul

Since size, addr, fcs, and tmp are unsigned, it would seem better to use
simple_strtoul that simple_strtol.

A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r2@
long e;
position p;
@@

e = simple_strtol@p(...)

@@
position p != r2.p;
type T;
T e;
@@

e =
- simple_strtol@p
+ simple_strtoul
  (...)

Subject: [PATCH 0897/1429] Bluetooth: Remove deprecated hci_usb driver

The old hci_usb driver has been fully replaced with the new btusb driver
and all major distributions switched to the new driver now. This removes
it since it should not be used at all anymore.

Subject: [PATCH 0898/1429] Bluetooth: Send HCI Reset command by default on
 device initialization

The Bluetooth subsystem was not using the HCI Reset command when doing
device initialization. The Bluetooth 1.0b specification was ambiguous
on how the device firmware was suppose to handle it. Almost every device
was triggering a transport reset at the same time. In case of USB this
ended up in disconnects from the bus.

All modern Bluetooth dongles handle this perfectly fine and a lot of
them actually require that HCI Reset is sent. If not then they are
either stuck in their HID Proxy mode or their internal structures for
inquiry and paging are not correctly setup.

To handle old and new devices smoothly the Bluetooth subsystem contains
a quirk to force the HCI Reset on initialization. However maintaining
such a quirk becomes more and more complicated. This patch turns the
logic around and lets the old devices disable the HCI Reset command.

The only device where the HCI_QUIRK_NO_RESET is still needed are the
original Digianswer devices and dongles with an early CSR firmware.

CSR reported that they fixed this for version 12 firmware. The last
official release of version 11 firmware is build ID 115. The first
version 12 candidate was build ID 117.

From a418b893a6af11ae73c762ed5b76c1bad6dc19d8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0900/1429] Bluetooth: Enable per-module dynamic debug messages

With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to
allow debugging without having to recompile the kernel. This patch turns
all BT_DBG() calls into pr_debug() to support dynamic debug messages.

As a side effect all CONFIG_BT_*_DEBUG statements are now removed and
some broken debug entries have been fixed.

Subject: [PATCH 0901/1429] Bluetooth: Fix format arguments warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Newer GCC versions are a little bit picky about how to deal with format
arguments:

net/bluetooth/hci_sysfs.c: In function ‘hci_register_sysfs’:
net/bluetooth/hci_sysfs.c:418: warning: format not a string literal and no format arguments

It is simple enough to fix and makes the compiler happy.

Subject: [PATCH 0902/1429] Bluetooth: Fix RFCOMM release oops when device is
 still in use

It turns out that the following sequence of actions will reproduce the
oops:

  1. Create a new RFCOMM device (using RFCOMMCREATEDEV ioctl)
  2. (Try to) open the device
  3. Release the RFCOMM device (using RFCOMMRELEASEDEV ioctl)

At this point, the "/dev/rfcomm*" device is still in use, but it is gone
from the internal list, so the device id can be reused.

  4. Create a new RFCOMM device with the same device id as before

And now kobject will complain that the TTY already exists.

(See http://lkml.org/lkml/2008/7/13/89 for a reproducible test-case.)

This patch attempts to correct this by only removing the device from the
internal list of devices at the final unregister stage, so that the id
won't get reused until the device has been completely destructed.

This should be safe as the RFCOMM_TTY_RELEASED bit will be set for the
device and prevent the device from being reopened after it has been
released.

Based on a report from Vegard Nossum <vegard.nossum@gmail.com>

Subject: [PATCH 0904/1429] dccp: Integrate feature-negotiation insertion code

The patch implements insertion of feature negotiation at the server (listening
and request socket) and the client (connecting socket).

In dccp_insert_options(), several statements have been grouped together now
to achieve (it is hoped) better efficiency by reducing the number of tests
each packet has to go through:
 - Ack Vectors are sent if the packet is neither a Data or a Request packet;
 - a previous issue is corrected - feature negotiation options are allowed
   on DataAck packets (5.8).

Subject: [PATCH 0905/1429] dccp: Preference list reconciliation

This provides two functions to
 * reconcile preference lists (with appropriate return codes) and
 * reorder the preference list if successful reconciliation changed the
   preferred value.

The patch also removes the old code for processing SP/NN Change options, since
new code to process these is mostly there already; related references have been
commented out.

The code for processing Change options follows in the next patch.

 options

This adds/replaces code for processing incoming ChangeL/R options.
The main difference is that:
 * mandatory FN options are now interpreted inside the function
  (there are too many individual cases to do this externally);
 * the function returns an appropriate Reset code or 0,
   which is then used to fill in the data for the Reset packet.

Old code, which is no longer used or referenced, has been removed.

Subject: [PATCH 0907/1429] dccp: Processing Confirm options

Analogous to the previous patch, this adds code to interpret incoming Confirm
feature-negotiation options. Both functions operate on the feature-negotiation
list of either the request_sock (server) or the dccp_sock (client).

Thanks to Wei Yongjun for pointing out that it is overly restrictive to check
the entire list of confirmed SP values.

Subject: [PATCH 0908/1429] dccp: Feature activation handlers

This patch provides the post-processing of feature negotiation state, after
the negotiation has completed.

To this purpose, handlers are used and added to the dccp_feat_table. Each
handler is passed a boolean flag whether the RX or TX side of the feature
is meant.

Several handlers are provided already, new handlers can easily be added.

The initialisation is now fully dynamic, i.e. CCIDs are activated only
after the feature negotiation. The integration of this dynamic activation
is done in the subsequent patches.

Thanks to Wei Yongjun for pointing out the necessity of skipping over empty
Confirm options while copying the negotiated feature values.

Subject: [PATCH 0909/1429] net: percpu_counter_inc() should not be called in
 BH-disabled section

Based upon a lockdep report by Alexey Dobriyan.

I checked all per_cpu_counter_xxx() usages in network tree, and I
think all call sites are BH enabled except one in
inet_csk_listen_stop().

commit dd24c00191d5e4a1ae896aafe33c6b8095ab4bd1
(net: Use a percpu_counter for orphan_count)
replaced atomic_t orphan_count to a percpu_counter.

atomic_inc()/atomic_dec() can be called from any context, while
percpu_counter_xxx() should be called from a consistent state.

For orphan_count, this context can be the BH-enabled one.

Subject: [PATCH 0914/1429] xfrm: Accept XFRM_STATE_AF_UNSPEC SAs on IPv4/IPv6
 only hosts

Installing SAs using the XFRM_STATE_AF_UNSPEC fails on hosts with
support for one address family only. This patch accepts such SAs, even
if the processing of not supported packets will fail.

Subject: [PATCH 0916/1429] hysdn: Kill directly reference of netdev->priv

Usually, netdev->priv should point to the memory of private
data which is allocated in alloc_netdev().
netdev_priv() is used to get the address of the private data.

Change the netdev->priv pointer to another memory is wrong.
Use netdev->ml_priv for this case.

Subject: [PATCH 0920/1429] forcedeth: power down phy when interface is down

Bring the physical link down when the interface is down by placing the PHY
in power-down state, unless WOL is enabled.  This mirrors the behavior of
other drivers including e1000 and tg3.

Without the patch, ifconfig down leaves the physical link up, which confuses
datacenter users who expect the link lights both on the NIC and the switch to
go out when they bring an interface down.

Furthermore, even though the phy is powered on, autonegotiation stops working,
so a normally gigabit link might suddenly become 100 Mbit half-duplex when the
interface goes down, and become gigabit when it comes up again.

Ayaz said:

  I would not include this patch until further testing is performed.  NVIDIA
  MCP chips use 3rd party PHY vendors.  By powering down the phy, it could
  have adverse affects on certain phys.

Arthur Jones said:

  I just ran across this patch.  Tested on a Marvell 88E1121R (GigE PHY)
  and works great.  This is a very important feature for me.

Subject: [PATCH 0923/1429] pkt_sched: sch_htb: Clean htb_class prio and
 quantum fields

While implementing htb_parent_to_leaf() there where added backup prio
and quantum struct htb_class fields to preserve these values for inner
classes in case of their return to leaf. This patch cleans this a bit
by removing union leaf duplicates.

Subject: [PATCH 0929/1429] jme: GHC register control fix for new hardware

Due to the hardware design, except the first chip on the market,
other chips needs to setup the clock source for MAC processor
implicitly through Global Host Control Register(GHC).
(Strange design huh?)

10/100M uses the PCI-E as clock source, and 1G uses GPHY.

And I reordered the code a little, to make it easier to read.

Subject: [PATCH 0936/1429] atm: 32-bit ioctl compatibility

We lack compat ioctl support through most of the ATM code. This patch
deals with most of it, and I can now at least use BR2684 and PPPoATM
with 32-bit userspace.

I haven't added a .compat_ioctl method to struct atm_ioctl, because
AFAICT none of the current users need any conversion -- so we can just
call the ->ioctl() method in every case. I looked at br2684, clip, lec,
mpc, pppoatm and atmtcp.

In svc_compat_ioctl() the only mangling which is needed is to change
COMPAT_ATM_ADDPARTY to ATM_ADDPARTY. Although it's defined as
	_IOW('a', ATMIOC_SPECIAL+4,struct atm_iobuf)
it doesn't actually _take_ a struct atm_iobuf as an argument -- it takes
a struct sockaddr_atmsvc, which _is_ the same between 32-bit and 64-bit
code, so doesn't need conversion.

Almost all of vcc_ioctl() would have been identical, so I converted that
into a core do_vcc_ioctl() function with an 'int compat' argument.

I've done the same with atm_dev_ioctl(), where there _are_ a few
differences, but still it's relatively contained and there would
otherwise have been a lot of duplication.

I haven't done any of the actual device-specific ioctls, although I've
added a compat_ioctl method to struct atmdev_ops.

Subject: [PATCH 0937/1429] netdev: remove pathetic compile-command lines

-m486, -O6 are partircularly amusing.

Remove some other useless lines near as well.

From 1ea472e2dedcf23d5f31c63fc790cccfab93c0de Mon Sep 17 00:00:00 2001
From: Benjamin Thery <benjamin.thery@bull.net>
Date: Wed, 3 Dec 2008 22:21:47 -0800
Subject: [PATCH 0938/1429] net: fix /proc/net/ip_mr_cache display - V2

/proc/net/ip_mr_cache and /proc/net/ip6_mr_cache displays garbage when
showing unresolved mfc_cache entries.

[root@qemu tests]# cat /proc/net/ip_mr_cache
Group    Origin   Iif     Pkts    Bytes    Wrong Oifs
014C00EF 010014AC 1         10    10050        0  2:1    3:1
024C00EF 010014AC 65535      514        2 -559067475

The first line is correct. It is a resolved cache entry, 10 packets used it...
The second line represents an unresolved entry, and the columns Pkts(4th),
Bytes(5th) and Wrong(6th) just show garbage.

In struct mfc_cache, there's an union to store data for resolved and
unresolved cases. And what ipmr_mfc_seq_show() is printing in these
columns for the unresolved entries is some bytes from mfc_cache.mfc_un.res.
Bad.
(eg. In our case -559067475 is in fact 0xdead4ead which is the spinlock
magic from mfc_cache.mfc_un.unres.unresolved.lock.magic).

This patch replaces the garbage data written in these columns for the
unresolved entries by '0' (zeros) which is more correct.
This change doesn't break the ABI.

Also, mfc->mfc_un.res.pkt, mfc->mfc_un.res.bytes, mfc->mfc_un.res.wrong_if
are unsigned long.

It applies on top of net-next-2.6.

The patch for net-2.6 is slightly different because of the NIP6_FMT to
%pI6 conversion that was made in the seq_printf.

Changelog:
==========
V2:
* Instead of breaking the ABI by suppressing the columns that have no
  meaning for unresolved entries, fill them with 0 values.

Subject: [PATCH 0939/1429] net: /proc/net/ip_mr_cache, display Iif as a signed
 short

Today, iproute2 fails to show multicast forwarding unresolved cache
entries while scanning /proc/net/ip_mr_cache.

Indeed, it expects to see -1 in 'Iif' column to identify unresolved
entries but the kernel outputs 65535. It's a signed/unsigned issue:

'Iif', the source interface, is retrieved from member mfc_parent in
struct mfc_cache. mfc_parent is a vifi_t: unsigned short, but is
displayed in ipmr_mfc_seq_show() as "%-3d", signed integer.

In unresolevd entries, the 65535 value (0xFFFF) comes from this define:
#define ALL_VIFS    ((vifi_t)(-1))

That may explains why the guy who added support for this in iproute2
thought a -1 should be expected.

I don't know if this must be fixed in kernel or in iproute2. Who is
right? What is the correct API? How was it designed originally?

I let you decide if it should goes in the kernel or be fixed in iproute2.

Subject: [PATCH 0940/1429] smc91x: remove isa stuff from smc91x driver

ISA support in smc91x is incomplete. I doubt there're any smc91x isa card.
This driver is greatly used on arm pxa platforms. Hence we remove the
isa stuff from smc91x driver.

Subject: [PATCH 0947/1429] xfrm: Accept ESP packets regardless of UDP
 encapsulation mode

From: Martin Willi <martin@strongswan.org>

An IPsec node speaking IKEv2 MUST accept incoming UDP encapsulated
ESP packets, even if no NAT situation is detected. This is important
if MOBIKE is in use. Some implementation keep the encapsulation
mode if they move out of a NAT situation.

Subject: [PATCH 0949/1429] mac80211: deauth when interface is marked down

It seems like proper etiquette to let other stations know when we are
going down in either STA or IBSS mode.  This also notifies userland, so
wpa_supplicant doesn't get confused.

Subject: [PATCH 0950/1429] mac80211: disassociate prior to unlinking
 AP/station

This patch reorders calls during disassociation in
ieee80211_set_disassoc function.
Since sta_info_unlink calls sta_notify(REMOVE) it will
remove the station representing AP from the driver before
it has disassociated from it using bss_info_changed callback.

Subject: [PATCH 0952/1429] mac80211: only transition STAs ps->wake on data
 frames

When a station goes to PS mode to scan, it will then send
probe requests without the PS bit set. mac80211 will take
that as indication that the station woke up, but it didn't.
This patch changes mac80211 to only consider doze->wake
transitions on data frames to to fix that issue.

Subject: [PATCH 0953/1429] nl80211: Add frequency configuration (including
 HT40)

This patch adds new NL80211_CMD_SET_WIPHY attributes
NL80211_ATTR_WIPHY_FREQ and NL80211_ATTR_WIPHY_SEC_CHAN_OFFSET to allow
userspace to set the operating channel (e.g., hostapd for AP mode).

Subject: [PATCH 0954/1429] nl80211: relicense nl80211.h under the ISC

We have a few BSD/ISC licensed userspace applications which
include nl80211.h from the kernel. To avoid legal ambiguity
for usage of the header file in these projects we rather simply
relicense the header file under the ISC. We've received consent
from all contributors to it.

the operating mode.  However, Atheros cards store PCU data in the high
16 bits of the mac address register.  Change ath5k_hw_set_lladdr() to
not clobber the PCU settings.

Subject: [PATCH 0957/1429] ath5k: clean up ath5k_hw_set_key

Status: O

With the addition of TKIP (and soon CCMP), key->alg is a more useful
guide to key type than the key length.

This patch cleans up key type assignment in ath5k_hw_set_key by
extracting it into its own function.  It also replaces the separate
memcpy() calls for extracting key material into the hardware format
with a loop that works regardless of key size.

Finally, the patch removes support for WEP-128 since it is a
non-standard key length that mac80211 also doesn't use.

Subject: [PATCH 0958/1429] ath5k: enable combined michael mic in key cache

For mac revisions >= "Griffin," the hardware allows the mic tx and rx
authenticator keys to share the same cache line, whereas earlier
hardware can only store the rx.  Enable the combined mic on hardware
that supports it.

8187B". For 8187 it should represent the number of retries (retry count
limit). As explained by Johannes Berg, .count represents the number of
tries (not retries), and retries = tries - 1.

Subject: [PATCH 0970/1429] mac80211: add sta_notify_ps callback

This patch is necessary in order to provide a proper Access point support for p54.
Unfortunately for us, there is no documented way to disable the interfering
power save buffering mechanism in firmware completely.

Therefore we give in and notify the driver through our new sta_notify_ps callback,
so that we can update the filter state.

Subject: [PATCH 0971/1429] p54: revamp station power save management in access
 point mode

This patch addresses the problem in:
http://marc.info/?l=linux-wireless&m=122727674810057&w=2

Thanks to Stefan Steuerwald <salsasepp@googlemail.com>
extensive iPod touch tests. We could finally squash some bugs in
p54's master mode / access point implementation.

Let's hope we got everything right this time and all stations
from now on will wake up on TIM and receive their queued frames
and go to sleep again without any hiccups.

Subject: [PATCH 0973/1429] p54: include support for 2.13.24.0 USB LM87
 Firmwares

Those firmwares are probably capable of reprogramming the device's eeprom.
We better support them officially, before all the accidents happen.

Subject: [PATCH 0974/1429] p54: refactoring

Thanks to the introduction of "changed" flags, we no longer
have to do the bookkeeping of p54's firmware state for everything.
Thus we can cut down redundancy code.

Subject: [PATCH 0975/1429] p54: per-device names

This patch replaces the static "p54:" strings in front of most printk's
with their corresponding per-device names.

It was always a bit of a hassle to check which device was
generating all the messages.

Subject: [PATCH 0978/1429] mac80211: tx module cleanup.

This patch removes unnecessary parameter in ieee80211_beacon_add_tim() and
removes unneeded definition and assignment for bdev (instance of net_device) in
ieee80211_beacon_get() and in ieee80211_get_buffered_bc()
(all in tx.c).

Subject: [PATCH 0979/1429] iwl3945: remove obsolete irq handling

3945 hardware does not emit the interrupts CSR_INT_BIT_RF_KILL (rfkill
toggled) and CSR_INT_BIT_CT_KILL (adapter too hot). Hence this part of code
can be removed since iwl3945_irq_tasklet does not handle 4965 hw at all.

This fixes the checksum calculation for lm87 firmwares
on big endian platforms, the device treats the data as
an array of 32-bit little endian values so the driver
needs to do that as well.

Subject: [PATCH 0982/1429] iwlwifi: disable AP mode

iwlwifi does not support AP mode in any way. For one, it doesn't even
buffer multicast/broadcast frames properly. We didn't allow zd1211rw AP
mode to be enabled without this, so iwlwifi shouldn't be allowed to
advertise AP mode either.

It also doesn't work at all, it doesn't even answer to probe requests,
I'm guessing the packet injection code was disabled again.

Subject: [PATCH 0990/1429] rt2x00: Optimize IV/EIV handling

IV and EIV belong to eachother and don't require
2 seperate fields. Instead they can logically be
merged into a single array with size 2.

With this approach we can simplify the code in
rt2x00crypto.c by using a single memcpy() when
copying the iv/eiv data. Additionally we can
move some code out of if-statements because the
if-statement would always be true.

Subject: [PATCH 0991/1429] rt2x00: Store retry limit values

Store retry limit values in the rt2x00dev structure.
This allows the removal of the FIXME where we assumed
the long retry is only used when working with RTS frames.

Instead we should check the current retry limit values
and decide if the required retry count for this frame
is a long or short retry.

Subject: [PATCH 0995/1429] iwlwifi: move host command check function into
 separate file

This patch moves iwl_check_rxon_cmd into iwl-agn-hcmd-check.c
This function compiled out in none debugging or non development
mode and more. We haven't decided which one yet hence preserving the
current 'always compile' state.
More functions will be added to the file namely for checking TX and LQ
commands.

The find_station routine needs to look at the IWL_AP_ID entry if we're a STA.
Currently, it only looks for STA entries which causes HW crypto to fail.

Subject: [PATCH 0999/1429] iwlwifi: move channels sysfs to debugfs

This patch moves channels info display from sysfs to debugfs.
This shows channel information as stored in NIC EEPROM. This
is useful in debugging CRDA or iwl goes setting so it belongs
rather to debugfs then to sysfs.

Subject: [PATCH 1002/1429] iwlwifi: fix DMA channel number in iwl_txq_ctx_stop

The patch fixes the misuse of DMA channel number by Tx queue number in
iwl_tx_ctx_stop().

The problem was originally reported by Wu Fengguang who complains
iwlagn driver takes too long time when issuing `ifconfig wlan0 down`.
The patch now decreases the interface bring down time from 2 seconds
to 0.8 second.

This fixes bugs:

We store the ucode version number as part of
iwl_priv/iwl3945_priv. This enables us to determine
if particular ucode has support for features in order
to have driver support more than one ucode API.

Subject: [PATCH 1004/1429] iwlwifi: rely on API version read from firmware

This adds the infrastructure to support older firmware APIs.
The API version number is stored as part of the filename, we first try to
load the most recent firmware and progressively try lower versions.
The API version is also read from the firmware self and stored as part
of the iwl_priv structure. Only firmware that is supported by driver will
be loaded. The version number read from firmware is compared
to supported versions in the driver not the API version used as part of
filename.

An example using this new infrastrucure:
   if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
        Driver interacts with Firmware API version >= 2.
   } else {
        Driver interacts with Firmware API version 1.
   }

Subject: [PATCH 1005/1429] iwl3945 : Fix a-band association for passive
 channels

Patch does following things
    1) This patch fixes the a-band association for passive channels with new
    uCode feature that it allows direct scan on passive channels after
    auto-switch from passive to active. This enables sending of direct probes
    on passive channels, as long as some traffic is detected on that channel.
    This improves the scanning for hidden SSIDs in A-band,which is all
    passive channels.

    This patch fixes the bug no 1748.

        http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748

    2) This fix will only work with uCode version 15.28.2.8 and above.
    Prior versions of uCode would work only if we heard the traffic within
     active dwell time, which is much shorter than passive dwell time and
    is shorter than typical beacon periods. This patch also provids full
    active dwell time even if we hear traffic late in passive dwell.

    3) uCode API version is incremented to 2.

Subject: [PATCH 1009/1429] rt2x00: Move crypto TX descriptor handling to
 rt2x00crypto.c

Move all code which determines the right TX descriptor
fields specific to crypto support into rt2x00crypto.c.
This makes the code in rt2x00queue more simpler and
better concentrates all crypto code into a single location.

With this we can also remove some ifdefs in rt2x00queue.c
since the code inside the ifdef is either very small, or
only calling empty functions (see empty function definitions
in rt2x00lib.h).

Subject: [PATCH 1012/1429] ath9k: Use GFP_ATOMIC when allocating TX private
 area

Using GFP_KERNEL was wrong and produces a 'scheduling while atomic'
bug as we're in a tasklet. Also, check for proper return values
now, in case allocation fails and be sure to stop the TX queue
in case of memory issues but gaurantee the TX queue will
eventually be woken up.

Subject: [PATCH 1014/1429] tty: Flags should be accessed via the foo_bit
 interfaces

We have various drivers that poke around directly and we need to clean this
up before it causes problems.

 arg pressure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are just too many args to some sacktag functions. This
idea was first proposed by David S. Miller around a year ago,
and the current situation is much worse that what it was back
then.

tcp_sacktag_one can be made a bit simpler by returning the
new sacked (it can be achieved with a single variable though
the previous code "caching" sacked into a local variable and
therefore it is not exactly equal but the results will be the
same).

tcp_minshall_update is not significant difference since it only
checks for not full-sized skb which is BUG'ed on the push_one
path anyway.

tcp_snd_test is tcp_nagle_test+tcp_cwnd_test+tcp_snd_wnd_test,

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since jiffies is unsigned long, the types get expanded into
that and after long enough time the difference will therefore
always be > 1 (and that probably happens near boot as well as
iirc the first jiffies wrap is scheduler close after boot to
find out problems related to that early).

This was originally noted by Bill Fink in Dec'07 but nobody
never ended fixing it.

Subject: [PATCH 1030/1429] staging-p80211: Kill directly reference of
 netdev->priv

In this driver, netdev's private data is wlandevice_t.  And the
wlandev(type of wlandevice_t) is exist before netdev be allocated.  So
use netdev->ml_priv to point to the private data.

I am not sure whether I should consider the kernel version older than
2.3.38.  Because in those kernels, netdevice_t is "structure dev"
instead of "structure net_device" and of course "dev->ml_priv" will
cause compile error.  But before my patch, in function wlan_setup(),
there is a ether_setup(net_device) which already broke kernels which
older than 2.3.38.

Subject: [PATCH 1032/1429] staging-winbond: Kill directly reference of
 netdev->priv

This driver is not yet finished.
At this time, we don't know how netdev be created and how
private data be allocated.
So, simply use netdev_priv() now and leave some temp comment.

Compile test only.

Subject: [PATCH 1033/1429] netdevice: Kill netdev->priv

This is the last shoot of this series.
After I removing all directly reference of netdev->priv, I am killing
"priv" of "struct net_device" and fixing relative comments/docs.

Anyone will not be allowed to reference netdev->priv directly.
If you want to reference the memory of private data, use netdev_priv()
instead.
If the private data is not allocted when alloc_netdev(), use
netdev->ml_priv to point that memory after you creating that private
data.

Subject: [PATCH 1034/1429] dccp: Integration of dynamic feature activation -
 part 1 (socket setup)

This first patch out of three replaces the hardcoded default settings with
initialisation code for the dynamic feature negotiation.

The patch also ensures that the client feature-negotiation queue is flushed
only when entering the OPEN state.

Since confirmed Change options are removed as soon as they are confirmed
(in the DCCP-Response), this ensures that Confirm options are retransmitted.

Note on retransmitting Confirm options:
---------------------------------------
Implementation experience showed that it is necessary to retransmit Confirm
options. Thanks to Leandro Melo de Sales who reported a bug in an earlier
revision of the patch set, resulting from not retransmitting these options.

As long as the client is in PARTOPEN, it needs to retransmit the Confirm
options for the Change options received on the DCCP-Response from the server.

Otherwise, if the packet containing the Confirm options gets dropped in the
network, the connection aborts due to undefined feature negotiation state.

Subject: [PATCH 1035/1429] dccp: Integration of dynamic feature activation -
 part 2 (server side)

This patch integrates the activation of features at the end of negotiation
into the server-side code.

Note regarding the removal of 'const':
--------------------------------------
 The 'const' attribute has been removed from 'dreq' since dccp_activate_values()
 needs to operate on dreq's feature list. Part of the activation is to remove
 those options from the list that have already been confirmed, hence it is not
 purely read-only.

Subject: [PATCH 1036/1429] dccp: Integration of dynamic feature activation -
 part 3 (client side)

This integrates feature-activation in the client:

 1. When dccp_parse_options() fails, the reset code is already set; request_sent\
    _state_process() currently overrides this with `Packet Error', which is not
    intended - changed to use the reset code supplied by dccp_parse_options().

 2. When feature negotiation fails, the socket should be marked as not usable,
    so that the application is notified that an error occurred. This is achieved
    by a new label 'unable_to_proceed': generating an error code of `Aborted',
    setting the socket state to CLOSED, returning with ECOMM in sk_err.

 3. Avoids parsing the Ack twice in Respond state by not doing option processing
    again in dccp_rcv_respond_partopen_state_process (as option processing has
    already been done on the request_sock in dccp_check_req).

Since this addresses congestion-control initialisation, a corresponding
FIXME has been removed.

Subject: [PATCH 1038/1429] dccp: Remove obsolete parts of the old CCID
 interface

The TX/RX CCIDs of the minisock are now redundant: similar to the Ack Vector
case, their value equals initially that of the sysctl, but at the end of
feature negotiation may be something different.

The old interface removed by this patch thus has been replaced by the newer
interface to dynamically query the currently loaded CCIDs.

Also removed are the constructors for the TX CCID and the RX CCID, since the
switch "rx <-> non-rx" is done by the handler in minisocks.c (and the handler
is the only place in the code where CCIDs are loaded).

Subject: [PATCH 1039/1429] dccp: Remove manual influence on NDP Count feature

Updating the NDP count feature is handled automatically now:
 * for CCID-2 it is disabled, since the code does not use NDP counts;
 * for CCID-3 it is enabled, as NDP counts are used to determine loss lengths.

Allowing the user to change NDP values leads to unpredictable and failing
behaviour, since it is then possible to disable NDP counts even when they
are needed (e.g. in CCID-3).

This means that only those user settings are sensible that agree with the
values for Send NDP Count implied by the choice of CCID. But those settings
are already activated by the feature negotiation (CCID dependency tracking),
hence this form of support is redundant.

At startup the initialisation of the NDP count feature uses the default
value of 0, which is done implicitly by the zeroing-out of the socket when
it is allocated. If the choice of CCID or feature negotiation enables NDP
count, this will then be updated via the NDP activation handler.

Subject: [PATCH 1040/1429] dccp ccid-2: Phase out the use of boolean Ack
 Vector sysctl

This removes the use of the sysctl and the minisock variable for the Send Ack
Vector feature, as it now is handled fully dynamically via feature negotiation
(i.e. when CCID-2 is enabled, Ack Vectors are automatically enabled as per
 RFC 4341, 4.).

Using a sysctl in parallel to this implementation would open the door to
crashes, since much of the code relies on tests of the boolean minisock /
sysctl variable. Thus, this patch replaces all tests of type

	if (dccp_msk(sk)->dccpms_send_ack_vector)
		/* ... */
with
	if (dp->dccps_hc_rx_ackvec != NULL)
		/* ... */

The dccps_hc_rx_ackvec is allocated by the dccp_hdlr_ackvec() when feature
negotiation concluded that Ack Vectors are to be used on the half-connection.
Otherwise, it is NULL (due to dccp_init_sock/dccp_create_openreq_child),
so that the test is a valid one.

The activation handler for Ack Vectors is called as soon as the feature
negotiation has concluded at the
 * server when the Ack marking the transition RESPOND => OPEN arrives;
 * client after it has sent its ACK, marking the transition REQUEST => PARTOPEN.

Adding the sequence number of the Response packet to the Ack Vector has been
removed, since
 (a) connection establishment implies that the Response has been received;
 (b) the CCIDs only look at packets received in the (PART)OPEN state, i.e.
     this entry will always be ignored;
 (c) it can not be used for anything useful - to detect loss for instance, only
     packets received after the loss can serve as pseudo-dupacks.

There was a FIXME to change the error code when dccp_ackvec_add() fails.
I removed this after finding out that:
 * the check whether ackno < ISN is already made earlier,
 * this Response is likely the 1st packet with an Ackno that the client gets,
 * so when dccp_ackvec_add() fails, the reason is likely not a packet error.

Subject: [PATCH 1044/1429] bluetooth: Fix unused var warning properly in
 rfcomm_sock_ioctl().

As Stephen Rothwell points out, we don't want 'sock' here but
rather we really do want 'sk'.

This local var is protected by all sorts of bluetooth debugging
kconfig vars, but BT_DBG() is just a straight pr_debug() call
which is unconditional.

pr_debug() evaluates it's args only if either DEBUG or
CONFIG_DYNAMIC_PRINTK_DEBUG is defined.

Solving this inside of the BT_DBG() macro is non-trivial since
it's varargs.  And these ifdefs are ugly.

So, just mark this 'sk' thing __maybe_unused and kill the ifdefs.

 htb_dequeue_tree() etc.

We can skip WARN_ON() in htb_dequeue_tree() because there should be
always a similar warning from htb_lookup_leaf() earlier.

The first WARN_ON() in in htb_lookup_leaf() is changed to BUG_ON()
because most likly this should end with oops anyway.

Use a small array in bond_mode_name() for the names, thus saving some
space:

Subject: [PATCH 1050/1429] bonding: fix compile error if debug enabled

This is what I get if debug is enabled:

drivers/net/bonding/bond_ipv6.c: In function 'bond_na_send':
drivers/net/bonding/bond_ipv6.c:75: error: 'slave' undeclared (first use in this function)
drivers/net/bonding/bond_ipv6.c:75: error: (Each undeclared identifier is reported only once
drivers/net/bonding/bond_ipv6.c:75: error: for each function it appears in.)

This patch fixes that.

Subject: [PATCH 1053/1429] bonding: make tbl argument to bond_parse_parm()
 const

bond_parse_parm() parses a parameter table for a particular value and
is therefore not modifying the table at all.  Therefore make the 2nd
argument const, thus allowing to make the tables const later.

Subject: [PATCH 1055/1429] igb: update handling of RCTL for smaller buffer
 sizes

As we begin to move into virtualization the use of a global value for
buffer sizes becomes undesirable.  This change makes it so only 256 and 512
byte buffers require use of the RCTL register.

 virtual environment

When running in a virtual environment the ports of an 82575/6 can appear to
be single function devices which is not correct.  To resolve this we rely
on the function number stored in the status register.

Subject: [PATCH 1060/1429] netns: ip6mr: allocate mroute6_socket
 per-namespace.

Preliminary work to make IPv6 multicast forwarding netns-aware.

Make IPv6 multicast forwarding mroute6_socket per-namespace,
moves it into struct netns_ipv6.

At the moment, mroute6_socket is only referenced in init_net.

Subject: [PATCH 1061/1429] netns: ip6mr: dynamically allocates vif6_table

Preliminary work to make IPv6 multicast forwarding netns-aware.

Dynamically allocates interface table vif6_table and moves it to
struct netns_ipv6, and updates MIF_EXISTS() macro.

At the moment, vif6_table is only referenced in init_net.

Subject: [PATCH 1062/1429] netns: ip6mr: store netns in struct mfc6_cache

This patch stores into struct mfc6_cache the network namespace each
mfc6_cache belongs to. The new member is mfc6_net.

mfc6_net is assigned at cache allocation and doesn't change during
the rest of the cache entry life.

This will help to retrieve the current netns around the IPv6 multicast
forwarding code.

At the moment, all mfc6_cache are allocated in init_net.

Changelog:
==========
* Use write_pnet()/read_pnet() to set and get mfc6_net.

Subject: [PATCH 1063/1429] netns: ip6mr: dynamically allocate mfc6_cache_array

Preliminary work to make IPv6 multicast forwarding netns-aware.

Dynamically allocates IPv6 multicast forwarding cache, mfc6_cache_array,
and moves it to struct netns_ipv6.

At the moment, mfc6_cache_array is only referenced in init_net.

Replace 'ARRAY_SIZE(mfc6_cache_array)' with mfc6_cache_array size: MFC6_LINES.

Subject: [PATCH 1064/1429] netns: ip6mr: declare counter
 cache_resolve_queue_len per-namespace

Preliminary work to make IPv6 multicast forwarding netns-aware.

Declare variable cache_resolve_queue_len per-namespace: moves it into
struct netns_ipv6.

This variable counts the number of unresolved cache entries queued in the
list mfc_unres_queue. This list is kept global to all netns as the number
of entries per namespace is limited to 10 (hardcoded in routine
ip6mr_cache_unresolved).
Entries belonging to different namespaces in mfc_unres_queue will be
identified by matching the mfc_net member introduced previously in
struct mfc6_cache.

Keeping this list global to all netns, also allows us to keep a single
timer (ipmr_expire_timer) to handle their expiration.
In some places cache_resolve_queue_len value was tested for arming
or deleting the timer. These tests were equivalent to testing
mfc_unres_queue value instead and are replaced in this patch.

At the moment, cache_resolve_queue_len is only referenced in init_net.

Subject: [PATCH 1066/1429] netns: ip6mr: declare reg_vif_num per-namespace

Preliminary work to make IPv6 multicast forwarding netns-aware.

Declare variable 'reg_vif_num' per-namespace, moves into struct netns_ipv6.

At the moment, this variable is only referenced in init_net.

Subject: [PATCH 1068/1429] netns: ip6mr: enable namespace support in ipv6
 multicast forwarding code

This last patch makes the appropriate changes to use and propagate the
network namespace where needed in IPv6 multicast forwarding code.

This consists mainly in replacing all the remaining init_net occurences
with current netns pointer retrieved from sockets, net devices or
mfc6_caches depending on the routines' contexts.

Some routines receive a new 'struct net' parameter to propagate the current
netns:
* ip6mr_get_route
* ip6mr_cache_report
* ip6mr_cache_find
* ip6mr_cache_unresolved
* mif6_add/mif6_delete
* ip6mr_mfc_add/ip6mr_mfc_delete
* ip6mr_reg_vif

All the IPv6 multicast forwarding variables moved to struct netns_ipv6 by
the previous patches are now referenced in the correct namespace.

Changelog:
==========
* Take into account the net associated to mfc6_cache when matching entries in
  mfc_unres_queue list.
* Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated
  per-namespace.
* Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net
  correctly.

Subject: [PATCH 1069/1429] netfilter: xt_NFLOG is dependant of nfnetlink_log

The patch "don't call nf_log_packet in NFLOG module" make xt_NFLOG
dependant of nfnetlink_log. This patch forces the dependencies to fix
compilation in case only xt_NFLOG compilation was asked and modifies the
help message accordingly to the change.

Subject: [PATCH 1072/1429] tc35815: Enable StripCRC feature

The chip can strip CRC automatically on receiving.  Enable it.

Also fix potential RX_BUF_SIZE calculation bug which was obscured by
alignment.  And use proper symbols (NET_IP_ALIGN, ETH_FCS_LEN, etc.)
instead of magic numbers.

Subject: [PATCH 1073/1429] net: Add support for the KS8695 ethernet devices.

Implements the KS8695 ethernet device (ks8695net).

This driver is only of use on the KS8695 which is an ARM9 based SoC. The
documentation on this SoC is sparse and poor, with barely a register
description and a rough outline of how the ethernet works, this driver was
therefore written with strong reference to the Micrel supplied Linux 2.6.9
port, and to Andrew Victor's ks8695eth driver.

Subject: [PATCH 1074/1429] rtl8187: Improve wireless statistics for RTL8187
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current wireless statistics for the RTL8187 poorly indicate the signal
strength and quality. With testing, I found that the AGC value is inversely
correlated with the strength as in the RTL8187B. By implementing a similar
calculation, much more code becomes common to the two devices.

Subject: [PATCH 1076/1429] mac80211: remove WARN_ON() from ieee80211_hw_config

ieee80211_hw_config can return an error when the hardware
has rfkill enabled. A WARN_ON() is too harsh for this
failure as it is a valid scenario. Only comment this warning
as we would like to have it back when rfkill is integrated into
mac80211.

Also reintroduce propagation of error if ieee80211_hw_config fails
in ieee80211_config_beacon.

This patch partially reverts patch:
5f0387fc3337ca26f0745f945f550f0c3734960f

Subject: [PATCH 1077/1429] iwlwifi: implement iwl_debug_report_frame for
 iwlagn

The old version of this code was copied from 3945 and never updated. This patch
cleans up structs that do not apply and accounts for other changes from
3945->iwlagn (e.g., PHY info can come in a separate cmd response from the
ucode.)

Subject: [PATCH 1078/1429] iwl3945: Fix rate scale for B-mode connection

This patch make sure we use only CCK rate for B only network.
For 3945 driver, it sets REPLY_RATE_SCALE command every time
we connect to a new network. In this command we set for every
rate the number of try and next rate. The problem mac80211 reports
same mode for both B and G mode as IEEE80211_BAND_2GHZ which will cause
using invalid rate other than CCK in B only network. THis patch
on association will examine sta valid rate on association, if no
OFDM rate in valid available rates it considers it as B only mode so
we can set REPLY_RATE_SCALE command with valid B only network and only
choose CCK rate in rate scaling.

Subject: [PATCH 1085/1429] ath9k: Disable staggered Beacon frame scheduling

It looks like there are some issues in the current ath9k version as
far as staggered Beacon frame scheduling is concerned. This results in
Beacon frame timestamp being off by 25 milliseconds or so which can
cause issues with multicast power save buffering in AP mode. Some
client stations fail to receive multicast frames when there is this
large an offset between TBTT and actual Beacon transmission time.

Since ath9k does not yet support multiple BSSes anyway, the staggered
Beacon frame scheduling is just increasing the number of interrupts at
this point. The easiest fix for the timestamp offset is to disable
staggered Beacon frames for now. We need to redesign beacon.c anyway
when adding multi-BSS support with mac80211 since the existing code
depends on different mechanism for Beacon frame transmission.

Subject: [PATCH 1086/1429] ath9k: Fix bug in rate table management

The proper rate table wouldn't be used if a disassoc
happens and a new attempt is made to associate using
wpa_supplicant. This patch fixes it by storing the rate
table to be used on association.

Subject: [PATCH 1087/1429] ath9k: Maintain rate table choice after association

A scan run after association would change sc_curmode which is
used to get the current rate table. This patch fixes it
by removing sc_curmode and setting the rate table in usage in cur_rate_table
on association.

Fix two small bugs with HT frequency setting:
 * HT is accepted even when the driver is incapable
 * HT40 is accepted when the driver cannot do 40 MHz
 (both on the selected band)

Also simplify the code a little.

Subject: [PATCH 1096/1429] ath9k: Incorrect band enum causes invalid antenna
 configuration.

It's a regression from the patch titled "ath9k: Use mac80211's band
macros and remove enum hal_freq_band". MAC80211 band macros can't be
mapped directly with our hal band enum.

Subject: [PATCH 1102/1429] mac80211: remove fragmentation offload
 functionality

There's no driver that actually does fragmentation on the
device, and the callback is buggy (when it returns an error,
mac80211's fragmentation status is changed so reading the
frag threshold from userspace reads the new value despite
the error). Let's just remove it, if we really find some
hardware supporting it we can add it back later.

Subject: [PATCH 1104/1429] ath9k: BH shouldn't be enabled when hardirqs are
 disabled.

ath_tx_complete_buf uses a BH version of spinlock and so releasing
the lock enables BH which is incorrect when called from sta_notify
callback as MAC80211 disables hardirqs before the driver callback
is called.

As ath_tx_complete_buf is shared between user and softirq context
using normal spinlock may not be appropriate. Though the proper
fix would be to cleanup the context properly in the driver code,
this would be an interim fix to avoid kernel warning.

Subject: [PATCH 1105/1429] p54usb: rewriting rx/tx routines to make use of
 usb_anchor's facilities
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Alan Stern found several flaws in p54usb's implementation and annotated:
"usb_kill_urb() and similar routines do not expect an URB's completion
routine to deallocate it.  This is almost obvious -- if the URB is deallocated
before the completion routine returns then there's no way for usb_kill_urb
to detect when the URB actually is complete."

This patch addresses all known limitations in the old implementation and fixes
khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

Subject: [PATCH 1106/1429] mac80211: integrate sta_notify_ps cmds into
 sta_notify

This patch replaces the newly introduced sta_notify_ps function,
which can be used to notify the driver about every power state
transition for all associated stations, by integrating its functionality
back into the original sta_notify callback.

Subject: [PATCH 1117/1429] rtl8187: Use usb anchor facilities to manage urbs

When SLUB debugging is enabled in the kernel, and the boot command includes
the option "slub_debug=P", rtl8187 encounters a GPF due to a read-after-free
of a urb.

Following the example of changes in p54usb to fix the same problem, the code
has been modified to use the usb_anchor_urb() method. With this change, the
USB core handles the freeing of urb's.

This patch fixes the problem reported in Kernel Bugzilla #12185
(http://bugzilla.kernel.org/show_bug.cgi?id=12185).

Subject: [PATCH 1119/1429] ipw2200: fix scanning while associated

This patch fixes sporadic firmware restarts when scanning while associated.

The firmware will quietly cancel a scan (while associated) if the dwell time
for a channel to be scanned is larger than the time it may stay away from the
operating channel (because of DTIM catching). Unfortunately the driver is not
notified about the canceled scan and therefore the scan watchdog timeout will
be hit and the driver causes a firmware restart which results in
disassociation. This mainly happens on passive channels which use a dwell time
of 120 whereas a typical beacon interval is around 100.

The patch changes the dwell time for passive channels to be slightly smaller
than the actual beacon interval to work around the firmware issue. Furthermore
the number of allowed beacon misses is increased from one to three as otherwise
most scans (while associated) won't complete successfully.

However scanning while associated will still fail in corner cases such as a
beacon intervals below 30.

Subject: [PATCH 1120/1429] mac80211: Disable requests for new scans in AP mode

AP mode operations are seriously affected if mac80211 runs through a
multi-second scan while the AP is trying to send Beacon frames on the
operation channel. While this could be implemented in a way that does
not cause too many problems, it is not very simple and will require
synchronization with Beacon frame scheduling in the drivers (scan one
channel at a time between Beacon frames). Furthermore, such scanning
takes quite a bit longer time and existing userspace applications
would be likely to timeout while waiting for the results.

For now, just refuse requests for new scans (SIOCSIWSCAN) when in AP
mode. In practice, this moves the rejection from iwl* drivers into
mac80211 to make it apply to every mac80211-based driver.

This issue shows up in associated stations getting disconnected when
something (e.g., Network Manager) requests a scan while the interface
is in AP mode. When doing this continuously (e.g., NM does it every 120
seconds), the network gets close to useless.

Subject: [PATCH 1123/1429] libertas: Create sysfs entry for changing the mesh
 probe response limit

This patch adds the ability to change the number of probe response retries sent
by the mesh interface.

In dense networks it is recommended to change this value to zero to reduce
traffic congestion.

Subject: [PATCH 1127/1429] ath9k: Do not remove header padding on RX from
 short frames

The 802.11 header is only padded to 32-bit boundary when the frame has
a non-zero length payload. In other words, control frames (e.g., ACK)
do not have a padding and we should not try to remove it. This fixes
monitor mode for short control frames. In addition, the hdrlen&3 use
is described in more detail to make it easier to understand how the
padding length is calculated.

Subject: [PATCH 1135/1429] mISDN: consistently define 'debug' as '*u_int'

Impact: change data type for variable 'debug' from *int to *u_int,
same for the argument type of mISDN_inittimer

In "core.h" mISDN_inittimer is declared with the argument type "*u_int", make
the definition in "timerdev.c" match this.

This fixes also this warnings:

Subject: [PATCH 1136/1429] mISDN: make global symbols static or include header
 files

The warnings fixed by including an header file for the appropriate
prototype are marked with "*", for all others the corresonponding
symbol has been made static.  This patch fixes all such issues in
mISDN.

Subject: [PATCH 1142/1429] mISDN: hfcmulti: use __iomem address space modifier

Impact: make use of the __iomem address space modifier, and change u_char *,
u_short * and u_int * to void *

Fix more than 30 sparse warnings of this or similar type:

  drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: warning: incorrect type in argument 2 (different address spaces)
  drivers/isdn/hardware/mISDN/hfcmulti.c:261:31:    got unsigned char [usertype] *
  drivers/isdn/hardware/mISDN/hfcmulti.c:261:31:    expected void volatile [noderef] <asn:2>*addr

Subject: [PATCH 1149/1429] sfc: Clean up waits for flash/EEPROM operations

Make falcon_spi_wait() ignore the write timer - it is only relevant to
write commands, it only works for the device that contains VPD, and it
might not be initialised properly at all.

Rename falcon_spi_fast_wait() to falcon_spi_wait_write(), reflecting
its use, and make it wait up to 10 ms (not 1 ms) since buffered writes
to EEPROM may take this long to complete.

Make both wait functions sleep instead of busy-waiting.

Replace wait for command completion at top of falcon_spi_cmd() with a
single poll; no command should be running when the function starts.

Correct some comments.

Subject: [PATCH 1150/1429] sfc: Work around unreliable strap pins

The SFC4000 has strap pins indicating the presence of SPI flash and/or
EEPROM.  These pins are also used for GPIO, and in some cases they may
be read wrongly at reset.  However, on production boards it must boot
from one or the other device, so we can assume the boot device is
present and read the board config from there.

Subject: [PATCH 1152/1429] sfc: Add option to use a separate channel for TX
 completions

In a bidirectional forwarding test, we find that the best performance
is achieved by sending the TX completion interrupts from one NIC to a
CPU which shares an L2 cache with RX completion interrupts from the
other NIC.  To facilitate this, add an option (through a module
parameter) to create separate channels for RX and TX completion with
separate IRQs when MSI-X is available.

Subject: [PATCH 1155/1429] sfc: Don't count RX checksum errors during loopback
 self-test

The loopback self-test checks that IP packets with incorrect checksums
are not altered when sent on a queue with checksum generation off.
These should not contribute to RX error statistics.

Subject: [PATCH 1160/1429] sfc: Clean up MDIO flag setting

We often want to set or clear a flag in an MDIO register, but avoid
writing if no change is required since this can have side-effects.
Encapsulate this in a function, mdio_clause45_set_flag().

Subject: [PATCH 1161/1429] sfc: Add support for sub-10G speeds

The SFC4000 has a separate MAC for use at sub-10G speeds.  Introduce
an efx_mac_operations structure with implementations for the two MACs.
Switch between the MACs as necessary.

PHY settings are independent of the MAC, so add get_settings() and
set_settings() to efx_phy_operations.  Also add macs field to indicate
which MACs the PHY is connected to.

From 04cc8cacb01c09fba2297faf1477cd570ba43f0b Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Fri, 12 Dec 2008 21:50:46 -0800
Subject: [PATCH 1162/1429] sfc: Implement auto-negotiation

Add infrastructure for auto-negotiation of speed, duplex and flow
control.

When using 10Xpress, auto-negotiate flow control.  While we're
at it, clean up the code to warn when partner is not 10GBASE-T
capable.

Subject: [PATCH 1163/1429] sfc: Rework MAC, PHY and board event handling

From: Steve Hodgson <shodgson@solarflare.com>

MAC, PHY and board events may be separately enabled and signalled.
Our current arrangement of chaining the polling functions can result
in events being missed.  Change them to be more independent.

From: Ben Hutchings <bhutchings@solarflare.com>
Date: Fri, 12 Dec 2008 22:00:17 -0800
Subject: [PATCH 1164/1429] sfc: Add support for Solarflare 10Xpress SFT9001

Add type codes for the new PHY and rename the SFX7101 type code.

Add definition of clause 22 extension MMD.

Adapt the 10Xpress SFX7101 code to support the SFT9001 as well.
Clean up register definitions.

Currently efx_mtd_rename() can race with the probe() and remove()
functions.

Move probe() before device registration and remove() after
unregistration.  Move initialisation/update of all names based on the
netdev name into a new function and call it under the RTNL immediately
after registration.

dcbml_setnumtcs wasn't checking for the presence of the setnumtcs
function.  Instead, it was checking for setstate which was a bug.

Subject: [PATCH 1191/1429] 8390/8390p: Fix compat netdev ops handling.

Based upon a report from Randy Dunlap.

The compat netdev ops assignments need to happen in
8390.c and 8390p.c, not lib8390.c, as only the type
specific code can assign the correct function pointers.

Subject: [PATCH 1192/1429] net: Add frag_list support to skb_segment

This patch adds limited support for handling frag_list packets in
skb_segment.  The intention is to support GRO (Generic Receive Offload)
packets which will be constructed by chaining normal packets using
frag_list.

As such we require all frag_list members terminate on exact MSS
boundaries.  This is checked using BUG_ON.

As there should only be one producer in the kernel of such packets,
namely GRO, this requirement should not be difficult to maintain.

Subject: [PATCH 1193/1429] net: Add frag_list support to GSO

This patch allows GSO to handle frag_list in a limited way for the
purposes of allowing packets merged by GRO to be refragmented on
output.

Most hardware won't (and aren't expected to) support handling GRO
frag_list packets directly.  Therefore we will perform GSO in
software for those cases.

However, for drivers that can support it (such as virtual NICs) we
may not have to segment the packets at all.

Whether the added overhead of GRO/GSO is worthwhile for bridges
and routers when weighed against the benefit of potentially
increasing the MTU within the host is still an open question.
However, for the case of host nodes this is undoubtedly a win.

Subject: [PATCH 1194/1429] net: Add Generic Receive Offload infrastructure

This patch adds the top-level GRO (Generic Receive Offload) infrastructure.
This is pretty similar to LRO except that this is protocol-independent.
Instead of holding packets in an lro_mgr structure, they're now held in
napi_struct.

For drivers that intend to use this, they can set the NETIF_F_GRO bit and
call napi_gro_receive instead of netif_receive_skb or just call netif_rx.
The latter will call napi_receive_skb automatically.  When napi_gro_receive
is used, the driver must either call napi_complete/napi_rx_complete, or
call napi_gro_flush in softirq context if the driver uses the primitives
__napi_complete/__napi_rx_complete.

Protocols will set the gro_receive and gro_complete function pointers in
order to participate in this scheme.

In addition to the packet, gro_receive will get a list of currently held
packets.  Each packet in the list has a same_flow field which is non-zero
if it is a potential match for the new packet.  For each packet that may
match, they also have a flush field which is non-zero if the held packet
must not be merged with the new packet.

Once gro_receive has determined that the new skb matches a held packet,
the held packet may be processed immediately if the new skb cannot be
merged with it.  In this case gro_receive should return the pointer to
the existing skb in gro_list.  Otherwise the new skb should be merged into
the existing packet and NULL should be returned, unless the new skb makes
it impossible for any further merges to be made (e.g., FIN packet) where
the merged skb should be returned.

Whenever the skb is merged into an existing entry, the gro_receive
function should set NAPI_GRO_CB(skb)->same_flow.  Note that if an skb
merely matches an existing entry but can't be merged with it, then
this shouldn't be set.

If gro_receive finds it pointless to hold the new skb for future merging,
it should set NAPI_GRO_CB(skb)->flush.

Held packets will be flushed by napi_gro_flush which is called by
napi_complete and napi_rx_complete.

Currently held packets are stored in a singly liked list just like LRO.
The list is limited to a maximum of 8 entries.  In future, this may be
expanded to use a hash table to allow more flows to be held for merging.

Subject: [PATCH 1195/1429] ipv4: Add GRO infrastructure

This patch adds GRO support for IPv4.

The criteria for merging is more stringent than LRO, in particular,
we require all fields in the IP header to be identical except for
the length, ID and checksum.  In addition, the ID must form an
arithmetic sequence with a difference of one.

The ID requirement might seem overly strict, however, most hardware
TSO solutions already obey this rule.  Linux itself also obeys this
whether GSO is in use or not.

In future we could relax this rule by storing the IDs (or rather
making sure that we don't drop them when pulling the aggregate
skb's tail).

Subject: [PATCH 1196/1429] net: Add skb_gro_receive

This patch adds the helper skb_gro_receive to merge packets for
GRO.  The current method is to allocate a new header skb and then
chain the original packets to its frag_list.  This is done to
make it easier to integrate into the existing GSO framework.

In future as GSO is moved into the drivers, we can undo this and
simply chain the original packets together.

Subject: [PATCH 1197/1429] tcp: Add GRO support

This patch adds the TCP-specific portion of GRO.  The criterion for
merging is extremely strict (the TCP header must match exactly apart
from the checksum) so as to allow refragmentation.  Otherwise this
is pretty much identical to LRO, except that we support the merging
of ECN packets.

Subject: [PATCH 1198/1429] ethtool: Add GGRO and SGRO ops

This patch adds the ethtool ops to enable and disable GRO.  It also
makes GRO depend on RX checksum offload much the same as how TSO
depends on SG support.

net/ipv4/ipmr.o.new:
 3 functions changed, 307 bytes added, 567 bytes removed, diff: -260

(Tested on x86_64).

It seems that pimlen arg could be left out as well and
eq-sizedness of structs trapped with BUILD_BUG_ON but
I don't think that's more than a cosmetic flaw since there
aren't that many args anyway.

Compile tested.

Subject: [PATCH 1205/1429] l2tp: fix UDP checksum support

The pppol2tp driver has had broken UDP checksum code for a long
time. This patch fixes it. If UDP checksums are enabled in the
tunnel's UDP socket, the L2TP driver now properly validates the
checksum on receive and fills in the checksum on transmit. If the
network device has hardware checksum support and is enabled, it is
used instead of generating/checking the checksum in software.

Subject: [PATCH 1207/1429] cxgb3: untie strict FW matching

The NIC driver can work with mutliple versions of the FW.
Let the driver load when the embedded FW does not match,
and the FW update mechanism failed.
The iWARP module will make its own loading decision.

Subject: [PATCH 1209/1429] net: Move flow control definitions to mii.h

flags used within drivers for indicating tx and rx flow control are
defined in 4 drivers (and probably more), move these constants to mii.h.

The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses
TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3.

Subject: [PATCH 1210/1429] net: Refactor full duplex flow control resolution

These 4 drivers have identical full duplex flow control resolution
functions.  This patch changes them all to use one common function.

The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

Subject: [PATCH 1211/1429] ipv6: Add IPV6_PKTINFO sticky option support to
 setsockopt()

There are three reasons for me to add this support:
1.When no interface is specified in an IPV6_PKTINFO ancillary data
  item, the interface specified in an IPV6_PKTINFO sticky optionis
  is used.

RFC3542:
6.7.  Summary of Outgoing Interface Selection

   This document and [RFC-3493] specify various methods that affect the
   selection of the packet's outgoing interface.  This subsection
   summarizes the ordering among those in order to ensure deterministic
   behavior.

   For a given outgoing packet on a given socket, the outgoing interface
   is determined in the following order:

   1. if an interface is specified in an IPV6_PKTINFO ancillary data
      item, the interface is used.

   2. otherwise, if an interface is specified in an IPV6_PKTINFO sticky
      option, the interface is used.

2.When no IPV6_PKTINFO ancillary data is received,getsockopt() should
  return the sticky option value which set with setsockopt().

RFC 3542:
   Issuing getsockopt() for the above options will return the sticky
   option value i.e., the value set with setsockopt().  If no sticky
   option value has been set getsockopt() will return the following
   values:

3.Make the setsockopt implementation POSIX compliant.

Subject: [PATCH 1215/1429] gianfar: Use gfar_halt to stop DMA in gfar_probe

gfar_halt does everything we want to do there, including disabling
TX/RX.  It also doesn't unnecessarily enable DMA if it's already
stopped.

Subject: [PATCH 1216/1429] gianfar: Convert gianfar to an of_platform_driver

Does the same for the accompanying MDIO driver, and then modifies the TBI
configuration method.  The old way used fields in einfo, which no longer
exists.  The new way is to create an MDIO device-tree node for each instance
of gianfar, and create a tbi-handle property to associate ethernet controllers
with the TBI PHYs they are connected to.

+As of this writing, every tsec is associated with an internal TBI PHY.
+This PHY is accessed through the local MDIO bus.  These buses are defined

Subject: [PATCH 1217/1429] gianfar: Optimize interrupt coalescing
 configuration

Store the interrupt coalescing values in the form in which they will be
written to the interrupt coalescing registers.  This puts a little overhead
into the ethtool configuration, and takes it out of the interrupt handler

Subject: [PATCH 1218/1429] gianfar: Fix eTSEC configuration procedure

Fix some bugs in the ethtool configuration functions:
* gfar_clean_rx_ring should not be called with interrupts disabled.
* Update last transmission time to avoid tx timeout.
* Delete redundant NETIF_F_IP_CSUM check in gfar_start_xmit
* Use netif_tx_lock_bh when reconfiguring the tx csum

Subject: [PATCH 1220/1429] gianfar: Enable padding and Optimize the frame
 prepended bytes handling

The eTSEC can prepend up to 32 bytes to a received frame, usually for the
purpose of aligning the IP address to a word boundary, so this turns it on.

While we're in there, make the handling of the pre-frame bytes (padding and
Frame Control Block) cleaner.

Subject: [PATCH 1222/1429] gianfar: Add macros for stepping through BDs

This code is based strongly on code from Dai Haruki <Dai.Haruki@freescale.com>.

The gianfar Buffer Descriptors are arranged in a circular array, the end of
which is denoted by setting the "WRAP" bit in the descriptor.  However, the
software knows the end of the ring because it knows how many descriptors are
there.  Rather than check each descriptor for whether the WRAP bit is set,
use pointer math to determine where the next BD is.  This is also useful for
when we want to look at BDs other than the very next one (for Scatter-Gather).

Subject: [PATCH 1223/1429] gianfar: Make all BD status writes 32-bit

Whenever we want to update the status field in a BD, we usually want to
update the length field, too.  By combining them into one 32-bit field, we
reduce the number of stores to memory shared with the controller, and we
eliminate the need for order-enforcement, as the length and "READY" bit are
now updated atomically at the same time.

 genphy_setup_forced

genphy_setup_forced hasn't actually reset the PHY for a long time,
but a comment to that effect remained in the code, so code continued
to act as if it *had* reset the PHY, and called the necessary fixup
functions to respond to a PHY reset.  With no reset, those functions
are no longer needed, so we remove them.

Subject: [PATCH 1229/1429] bnx2x: Fix namespace collision with
 FLOW_CTRL_{TX,RX}

These are now defined in linux/mii.h and the bnx2x driver
defines different values which are shared with hardware
data structures.

So add a "BNX2X_" prefix to these macro names.

Based upon a report from Stephen Rothwell.

Subject: [PATCH 1230/1429] net: ppp_generic - use idr technique instead of
 cardmaps

Use idr technique instead of own implemented cardmaps.
It saves us a number of lines and gives an ability
to use library functions.

Subject: [PATCH 1237/1429] dccp_diag: LISTEN sockets don't have CCIDs

And thus when we try to use 'ss -danemi' on these sockets that have no
ccid blocks (data collected using systemtap after I fixed the problem):

dccp_diag_get_info sk=0xffff8801220a3100, dp->dccps_hc_rx_ccid=0x0000000000000000, dp->dccps_hc_tx_ccid=0x0000000000000000

We get an OOPS:

mica.ghostprotocols.net login: BUG: unable to handle kernel NULL pointer
dereferenc0
IP: [<ffffffffa0136082>] dccp_diag_get_info+0x82/0xc0 [dccp_diag]
PGD 12106f067 PUD 122488067 PMD 0
Oops: 0000 [#1] PREEMPT

Fix is trivial, and 'ss -d' is working again:

[root@mica ~]# ss -danemi

Subject: [PATCH 1238/1429] gianfar: Fix packet drop when out of memory

The patch which fixed gianfar so it drops packets when it runs out
of memory left in the code which frees the skb when it drops packets.
Change the code so that we only free the skb if the new skb was successfully
created.

Subject: [PATCH 1240/1429] gianfar: Use interface name in interrupt name to
 distinguish the source.

Interface name (ex. eth0) is used as the prefix for the interrupt name,
with _rx, _tx, and _er appended to distinguish multiple interrupts on
the same interface.

gfar_poll would declare polling done once the rx queue was empty,
but the tx queue could still have packets left.

Stolen mostly from the e1000 driver.

Subject: [PATCH 1244/1429] bonding: introduce and use port_params structure

It generally helps to handle those values in various places, using it
might make the code more readable and gives room for other improvements.

The IEEE standard talks about them as "parameter values".

|     netdevice zd1201: Convert directly reference of netdev->priv to netdev_priv()
|
|     We have some reasons to kill netdev->priv:
|     1. netdev->priv is equal to netdev_priv().
|     2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
|        netdev_priv() is more flexible than netdev->priv.
|     But we cann't kill netdev->priv, because so many drivers reference to it
|     directly.
|
|     OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
|     and I want to kill netdev->priv later, I decided to convert all the direct
|     reference of netdev->priv first.
|
|     (Original patch posted by Wang Chen <wangchen@cn.fujitsu.com> w/ above
|     changelog but using dev->ml_priv.  That doesn't seem appropriate
|     to me for this driver, so I've revamped it to use netdev_priv()
|     instead. -- JWL)

This commit changed the allocation of netdev, but didn't change
the free method of it.
This causes "zd" be used after the memory, which is pointed by "zd", being
freed by free_netdev().

Subject: [PATCH 1255/1429] enc28j60: reduce the number of spi transfers in
 enc28j60_set_bank()

A major source of overhead in the enc28j60 driver is the SPI transfers. Each
SPI transfer entails two kernel thread context switches. One major source of
SPI transfers is the enc28j60_set_bank() functions which runs before every
register access. This patch reduces the number of SPI transfers that
enc28j60_set_bank() performs in two ways:

  1. removes unnecessary bank switch for the registers that are present in all
	 banks

  2. when switching from banks 0 or 3 to banks 1 or 2 (i.e. only one bit
	 changes) enc28j60_set_bank() does only one SPI transfer instead of two

According to my tests these changes reduce the number of SPI transfers in
about 25%.

Subject: [PATCH 1256/1429] NIU: Implement discard counters

Implementing discard counters for the NIU driver turned out to be more
complicated than first assumed.

The discard counters for the NIU neptune chip are only 16-bit (even
though this is a 64-bit chip).  These 16-bit counters can overflow
quickly, especially considering this is a 10Gbit/s ethernet card.

The overflow indication bit is, unfortunatly, not usable as the
counter value does not wrap, but remains at max value 0xFFFF.
Resulting in lost counts until the counter is reset.

The read and reset scheme also poses a problem. Both in theory and in
practice counters can be lost in between reading nr64() and clearing
the counter nw64().  For this reason, the number of counter clearings
nw64() is limited/reduced.  On the fast-path the counters are only
syncronized once it exceeds 0x7FFF.  When read by userspace, its
syncronized fully.

Subject: [PATCH 1260/1429] ucc_geth: Fix endless loop in stop_{tx,rx} routines

Currently the routines wait for the various bits w/o an assumption that
bits may never get set. When timeouts happen I see that these bits never
get set and so the routines hang the kernel.

With this patch we'll wait the graceful stop for 100 ms, and then will
simply exit. There is nothing* we can do about that, but it's OK since
we'll do full reset later.

* Well, actually, there is also not-graceful variant for the TX stop,
  but specs says that we never should use it.

Subject: [PATCH 1261/1429] ucc_geth: Fix TX watchdog timeout handling

The timeout handling code is currently broken in several ways:

- It calls stop() (which frees all the memory and IRQ), and then
  calls startup() (which won't re-request IRQ, neither it will
  re-init the Fast UCC structure).
- It calls these routines from the softirq context, which is wrong,
  since stop() calls free_irq() (which might sleep) and startup()
  allocates things with GFP_KERNEL.
- It won't soft-reset the PHY. We need the PHY reset for at least
  MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover
  from timeouts w/o the reset.

So the patch fixes these problems by implementing the workqueue for the
timeout handling, and there we fully re-open the device via close() and
open() calls. The close/open paths do the right things, and I can see
that the driver actually survive the timeouts.

Subject: [PATCH 1262/1429] ucc_geth: Fix IRQ freeing code in ucc_geth_open()

open() routine calls stop() in case of errors, the function will try
to free the requested IRQ. But we don't know if it was actually
requested, so the code might issue bogus free_irq(0, dev) call.

Fix this by rearranging the code so that now request_irq() is the last
call in the open() routine, and move free_irq() into the close().

The ucc_geth_stop() may be called anytime and will do the right thing.

Subject: [PATCH 1264/1429] ucc_geth: Fix IO memory (un)mapping code

The driver doesn't check ioremap() return value, and doesn't free the
remapped memory.

This patch fixes it.

Subject: [PATCH 1265/1429] ucc_geth: Remove UGETH_FILTERING dead code

The code appears to be dead: nobody call these functions, plus build
breaks when UGETH_FILTERING is enabled:

make[2]: *** [ucc_geth.o] Error 1

The code is there since the driver was merged, and nobody seem to be
interested in fixing or actually using it. If we ever want the
filtering support, we can always revert the patch and fix it, but so
far it just draws reader's attention.

Subject: [PATCH 1266/1429] cxgb3: manage private iSCSI IP address

The accelerated iSCSI traffic could use a private IP address unknown to the OS:
- The IP address is required in both drivers to manage ARP requests and connection set up.
- Added an control call to retrieve the ip address.
- Reply to ARP requests dedicated to the private IP address.

Subject: [PATCH 1270/1429] mac80211: Fix HT channel selection

HT management is done differently for AP and STA modes, unify
to just the ->config() callback since HT is fundamentally a
PHY property and cannot be per-BSS.

Rename enum nl80211_sec_chan_offset as nl80211_channel_type to denote
the channel type ( NO_HT, HT20, HT40+, HT40- ).

Subject: [PATCH 1271/1429] ath9k: Do not use association state to update rate
 table

Now that HT information is made available to the driver through
config() callback, the channel type can be calculated whenever
setting the channel. Update the rate table accordingly with the new
channel type.

Subject: [PATCH 1272/1429] mac80211: Add HT rates into RX status reporting

This patch adds option for HT-enabled drivers to report HT rates
(HT20/HT40, short GI, MCS index) to mac80211. These rates are
currently not in the rate table, so the rate_idx is used to indicate
MCS index.

Subject: [PATCH 1273/1429] ath9k: Report HT rates in RX status

Fix and clean up the RX status reporting by getting rid of code that
used internal rate tables and ratekbps calculation. The correct value
is now reported with MCS index instead of the old mechanism that
defaulted to using the highest legacy rate.

Subject: [PATCH 1274/1429] ath5k: fix 802.11 header padding on RX, unpadding
 on TX

Padding the 802.11 header to a multiple of 4 bytes needs to be done only for
frames with a body. This fixes a bug where 2 bytes were missing in monitor
mode for ACK frames. Inspired by a patch from Jouni Malinen on ath9k.

Subject: [PATCH 1275/1429] mac80211: Send Layer 2 Update frame on
 reassociation

When a STA roams back to the same AP before the previous STA entry has
expired, a new STA entry is not added in mac80211. However, a Layer 2
Update frame still needs to be transmitted to update layer 2 devices
about the new location for the STA. Without this, switches may
continue to forward frames to the previous (now incorrect) port when
STA roams between APs.

    Rate scaling in agn can be broken because of these two problems
    1- the LQ command could not sent, we try to call LQ command before
       post association will be rejected, this will cause the driver to
       break in rs_tx_status reporting initial rate does not match.
    2- In rs_rate_init we can get a value of 12, rate 60, for
       last_txrate_idx, this rate only valid in SISO/MIMO mode only

Subject: [PATCH 1277/1429] p54: move statistic timer update routine into a
 workqueue

This patch moves a good chunk of code from the former statistic update
timer routine into a workqueue, which is kindly provided by mac80211.

Also as a nice side-effect we can lay the foundation for other
essential housekeeping features we want to do in the future.
e.g:
 - drain the (clogged) tx_queue.
 - initiate bursts.

Subject: [PATCH 1282/1429] p54: remove free_on_tx parameter

This patch simplifies the tx code a bit and will be necessary for
the upcoming stlc45xx<->p54 port.

In detail: we no longer have to tell all back-end drivers directly,
if we want to free a frame right after it was send to the firmware,
or if we do it in the library callback later.

Subject: [PATCH 1283/1429] rtl8187: Fix crash on unload when using SLUB debug

Reported-by: Hin-Tak Leung <htl10@users.sourceforge.net>

After the code was modified to use urb anchors ("rtl8187: Use usb anchor
facilities to manage urbs"), rtl8187 began generating an intermittent GPF
on shutdown when using SLUB with debugging enabled. Furthermore, rebooting
the system with a ping running caused a GPF every time. There are two problems:
(1) incorrect locking in the rtl8187_rx_cb() routine, a pre-existing bug that
apparently had not been triggered before, and (2) duplicate freeing of receive
skbs that was probably introduced with the change to anchors.

Subject: [PATCH 1284/1429] mac80211: Remove radiotap rate-present flag for HT

Since we do not currently report HT rates (MCS index) in radiotap
header for HT rates, we should not claim the rate is present. The rate
octet itself is used as padding in this case, so only the it_present
flag needs to be removed in case of HT rates.

The count field in struct ieee80211_tx_rate does not include the final
successful attempt, so only report retries here.

Fix the struct ieee80211_tx_rate::idx field when MCS was used. It is
supposed to be the MCS index, not an internal index to the rate
control algorithm table.

Remove the possible MAC header pad before reporting TX status to
mac80211. This pad is hardware specific operation and should not be
exposed outside the driver. This fixes the frame body in monitor
interfaces that could be used to check on TX status for transmitted
frames.

This patch fixes a typo in ieee80211_send_assoc(), net/mac80211/mlme.c.

The error is usage of a wrong member when building
the ie80211 management frame (it should be assoc_req, and not reassoc_req).

Subject: [PATCH 1297/1429] iwlwifi: use GFP_KERNEL to allocate Rx SKB memory

Previously we allocate Rx SKB with GFP_ATOMIC flag. This is because we need
to hold a spinlock to protect the two rx_used and rx_free lists operation
in the rxq.

	spin_lock();
	...
	element = rxq->rx_used.next;
	element->skb = alloc_skb(..., GFP_ATOMIC);
	list_del(element);
	list_add_tail(&element->list, &rxq->rx_free);
	...
	spin_unlock();

After spliting the rx_used delete and rx_free insert into two operations,
we don't require the skb allocation in an atomic context any more (the
function itself is scheduled in a workqueue).

	spin_lock();
	...
	element = rxq->rx_used.next;
	list_del(element);
	...
	spin_unlock();
	...
	element->skb = alloc_skb(..., GFP_KERNEL);
	...
	spin_lock()
	...
	list_add_tail(&element->list, &rxq->rx_free);
	...
	spin_unlock();

This patch should fix the "iwlagn: Can not allocate SKB buffers" warning
we see recently.

Subject: [PATCH 1305/1429] ath9k: Fixed RX decryption status reporting

The RX code in ath9k uses sc_keymap to figure out whether a default
key was used. However, the default key entries in sc_keymap were
always set and as such, frames could have been claimed to be decrypted
by hardware when they were not. This can cause problems especially
with TKIP since mac80211 is validating the Michael MIC in the frame
and this will result in MIC failure and potentially TKIP
countermeasures if the frame was not decrypted correctly.

Change key cache slot allocation to mark only the keys that really
have been used in sc_keymap to avoid the issue. The key cache slot
selection routines are now internally avoiding the slots that may be
needed for TKIP group keys.

Subject: [PATCH 1307/1429] b43: Fix some MAC locking

This fixes some locking w.r.t. the lower MAC (firmware).
It also removes a lot of ancient IRQ-locking that's not needed anymore.
We simply suspend the MAC. That's easier and causes less trouble.

Subject: [PATCH 1308/1429] mac80211: enable IEEE80211_CONF_PS only when
 associated

Also disable power save when disassociated. It makes no sense to have
power save enabled while disassociated.

iwlwifi seems to have this check in the driver, but it's better to do this
in mac80211 instead.

Subject: [PATCH 1309/1429] mac80211: track master queue status

This is a preparation for the dynamic power save support. In future there are
two paths to stop the master queues and we need to track this properly to
avoid starting queues incorrectly. Implement this by adding a status
array for each queue.

The original idea and design is from Johannes Berg, I just did
the implementation based on his notes. All the bugs are mine, of course.

Subject: [PATCH 1310/1429] mac80211: implement dynamic power save

This patch implements dynamic power save for mac80211. Basically it
means enabling power save mode after an idle period. Implementing it
dynamically gives a good compromise of low power consumption and low
latency. Some hardware have support for this in firmware, but some
require the host to do it.

The dynamic power save is implemented by adding an timeout to
ieee80211_subif_start_xmit(). The timeout can be enabled from userspace
with Wireless Extensions. For example, the command below enables the
dynamic power save and sets the time timeout to 500 ms:

iwconfig wlan0 power timeout 500m

Power save now only works with devices which handle power save in firmware.
It's also disabled by default and the heuristics when and how to enable is
considered as a policy decision and will be left for the userspace to handle.
In case the firmware has support for this, drivers can disable this feature
with IEEE80211_HW_NO_STACK_DYNAMIC_PS.

Big thanks to Johannes Berg for the help with the design and code.

Subject: [PATCH 1327/1429] net: fix DCB setstate to return success/failure

Data Center Bridging (DCB) had no way to know if setstate had failed in the
driver.  This patch enables dcb netlink code to handle the status for the DCB
setstate interface.  Likewise it allows the driver to return a failed status
if MSI-X isn't enabled.

Subject: [PATCH 1328/1429] net: add DCNA attribute to the BCN interface for
 DCB

Adds the Backward Congestion Notification Address (BCNA) attribute to the
Backward Congestion Notification (BCN) interface for Data Center Bridging
(DCB), which was missing.  Receive the BCNA attribute in the ixgbe driver.
The BCNA attribute is for a switch to inform the endstation about the physical
port identification in order to support BCN on aggregated links.

Subject: [PATCH 1331/1429] tg3: WOL fixes

The first hunk of this patch inverts a flag that was accidentally
toggled as part of commit 0a459aac9d151c2e36ec65723b9b845b24c5cbc3
("tg3: Allow WOL for phylib controlled Broadcom phys").

The second hunk of the patch removes the call to
device_may_wakeup() in the 5906 config detection path.  At the
point of the call, the driver shouldn't be querying for WOL
capability.  It should be detecting and setting it.

Subject: [PATCH 1333/1429] tg3: Remove unused cfgspc device members

This patch removes the pci_bist and pci_hdr_type members from the
device structure and removes the code that references them.  They are
not really used.

The patch rounds out the changes by moving the pci_cmd member to plug
a structure hole that would have been created.  On 32-bit systems, this
movement removes a subsequent structure hole later in the structure. On
64-bit systems though, the movement merely consolidates two holes into
one larger hole.

Subject: [PATCH 1334/1429] tg3: tg3.h cleanups

This patch cleans up the tg3 header file by removing the preprocessor
definitions for standard PCI configuration space registers.  The driver
should be using the standard definitions when needed.  The patch
continues by removing redundant PHY related definitions and reorganizes
some of the remaining entries.

While implementing a TCQ_F_THROTTLED flag there was used an smp_wmb()
in qdisc_watchdog(), but since this flag is practically used only in
sch_netem(), and since it's not even clear what reordering is avoided
here (TCQ_F_THROTTLED vs. __QDISC_STATE_SCHED?) it seems the barrier
could be safely removed.

Subject: [PATCH 1341/1429] net: startup race in hso driver

The flag marking a device running must be set before the URBs for
recption are submitted or they may complete too early and fail to resubmit.

Subject: [PATCH 1342/1429] net: Remove unused netdev arg from some NAPI
 interfaces.

When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

Subject: [PATCH 1343/1429] smsc911x: fix BUG if module is removed while
 interface is up

If the module is removed while its interface is up, smsc911x_stop is not
called until after smsc911x_drv_remove has disposed of phy_dev.  This
patch changes the stop method to handle this situation.

This is a different problem to the one reported by dfoley@telus.net.

Subject: [PATCH 1350/1429] vlan: fix convertion to net_device_ops

commit 656299f706e52e0409733d704c2761f1b12d6954
(vlan: convert to net_device_ops) added a net_device_ops
with a NULL ndo_start_xmit field.

This gives a crash in dev_hard_start_xmit()

Fix it using two net_device_ops structures, one for hwaccel vlan,
one for non hwaccel vlan.

The PHYLIB mdio code has more problems in error paths:
- mdiobus_release can be called before bus->state is set to
  MDIOBUS_REGISTERED
- mdiobus_scan allocates resources which need to be freed
- the comment is wrong, the resistors used are actually pull-ups.

Subject: [PATCH 1355/1429] sctp: Avoid memory overflow while FWD-TSN chunk is
 received with bad stream ID

If FWD-TSN chunk is received with bad stream ID, the sctp will not do the
validity check, this may cause memory overflow when overwrite the TSN of
the stream ID.

The FORWARD-TSN chunk is like this:

FORWARD-TSN chunk
  Type                       = 192
  Flags                      = 0
  Length                     = 172
  NewTSN                     = 99
  Stream                     = 10000
  StreamSequence             = 0xFFFF

This patch fix this problem by discard the chunk if stream ID is not
less than MIS.

Subject: [PATCH 1357/1429] tcp: Always set urgent pointer if it's beyond
 snd_nxt

Our TCP stack does not set the urgent flag if the urgent pointer
does not fit in 16 bits, i.e., if it is more than 64K from the
sequence number of a packet.

This behaviour is different from the BSDs, and clearly contradicts
the purpose of urgent mode, which is to send the notification
(though not necessarily the associated data) as soon as possible.
Our current behaviour may in fact delay the urgent notification
indefinitely if the receiver window does not open up.

Simply matching BSD however may break legacy applications which
incorrectly rely on the out-of-band delivery of urgent data, and
conversely the in-band delivery of non-urgent data.

Alexey Kuznetsov suggested a safe solution of following BSD only
if the urgent pointer itself has not yet been transmitted.  This
way we guarantee that when the remote end sees the packet with
non-urgent data marked as urgent due to wrap-around we would have
advanced the urgent pointer beyond, either to the actual urgent
data or to an as-yet untransmitted packet.

The only potential downside is that applications on the remote
end may see multiple SIGURG notifications.  However, this would
occur anyway with other TCP stacks.  More importantly, the outcome
of such a duplicate notification is likely to be harmless since
the signal itself does not carry any information other than the
fact that we're in urgent mode.

Subject: [PATCH 1358/1429] netlink: fix (theoretical) overrun in message
 iteration

See commit 1045b03e07d85f3545118510a587035536030c1c ("netlink: fix
overrun in attribute iteration") for a detailed explanation of why
this patch is necessary.

In short, nlmsg_next() can make "remaining" go negative, and the
remaining >= sizeof(...) comparison will promote "remaining" to an
unsigned type, which means that the expression will evaluate to
true for negative numbers, even though it was not intended.

I put "theoretical" in the title because I have no evidence that
this can actually happen, but I suspect that a crafted netlink
packet can trigger some badness.

Note that the last test, which seemingly has the exact same
problem (also true for nla_ok()), is perfectly OK, since we
already know that remaining is positive.

Subject: [PATCH 1365/1429] forcedeth: don't poll NV event 36

Polling doesn't seem to be necessary on my hardware, at
least I haven't seen any bad effects testing it a while.
Remove the polling so the CPU doesn't have to wake up a
hundred times per second.

Update myri10ge firmware headers to 1.4.37:
* Make each member of the error/cmd enum an initialized one, so there
  is a convenient numerical reference to look for reverse conversion.
* Add new MXGEFW_CMD_RELAX_RXBUFFER_ALIGNMENT command.
* Add new "features" field to mcp_header.

Subject: [PATCH 1369/1429] mlx4_en: Removed TX locking when polling TX cq

There is no need to synchronize the polling with the transmit
function. The only place to synchronize is when we process
the cq from the transmit function. Also removed spin_lock_irq,
and using spin_trylock, if somebody else is already processing the cq,
no need to wait for it to finish.

(When slub debug is disabled it works fine.)

PAGE_SIZE allocations via slab are not guaranteed to be page-aligned;
use get_zeroed_page for the 'pt' buffer (I don't really know what this
is, only that it is passed to firmware and that the first error
message complains about its alignment).  This allows the system to
boot.

is the only caller, so comment it out as well.

 un-EXPORT symbols

The symbols are only references within the translation unit they are
defined in, so un-EXPORT them und make them 'static'.

Fix this sparse warnings:

  drivers/net/wan/z85230.c:604:25: warning: symbol 'z8530_dma_sync' was not declared. Should it be static?
  drivers/net/wan/z85230.c:613:25: warning: symbol 'z8530_txdma_sync' was not declared. Should it be static?

Subject: [PATCH 1399/1429] drivers/net/wireless/prism54: fix sparse warnings:
 make symbols static

Fix this sparse warnings:

  drivers/net/wireless/prism54/islpci_hotplug.c:97:1: warning: symbol 'prism54_probe' was not declared. Should it be static?
  drivers/net/wireless/prism54/islpci_hotplug.c:220:1: warning: symbol 'prism54_remove' was not declared. Should it be static?
  drivers/net/wireless/prism54/islpci_hotplug.c:263:1: warning: symbol 'prism54_suspend' was not declared. Should it be static?
  drivers/net/wireless/prism54/islpci_hotplug.c:286:1: warning: symbol 'prism54_resume' was not declared. Should it be static?

Subject: [PATCH 1406/1429] igb: defeature tx head writeback

This patch removes tx head writeback as it was found to not provide a
significant improvement in tx performance and on some systems has been seen
to cause a performance degredation due to partial cache line writes.

Subject: [PATCH 1407/1429] igb: re-order queues to support cleaner use of ivar
 on 82576

The 82576 adapter orders the queues in pairs when virtualization is in use.
The queue ordering previously conflicted with the ordering when sr-iov was
enabled.  This new ordering allows a PF to allocate 2 queues without using
any VF resources.

Subject: [PATCH 1408/1429] net: Init NAPI dev_list on napi_del

The recent GRO patches introduced the NAPI removal of devices in
free_netdev.  For drivers that can change the number of queues during
driver operation, the NAPI infrastructure doesn't allow the freeing and
re-addition of NAPI entities without reloading the driver.

This change reinitializes the dev_list in each NAPI struct on delete,
instead of just deleting it (and assigning the list pointers to POISON).
Drivers that wish to remove/re-add NAPI will need to re-initialize the
netdev napi_list after removing all NAPI instances, before re-adding NAPI
devices again.

 memory pools.

The adapter rings are kcalloc()'d, but in set_ringparam() in ixgbe_ethtool,
we replace that memory from the vmalloc() pool.  This can result in a NULL
pointer reference when trying to modify the rings at a later time, or on
device removal.

Subject: [PATCH 1417/1429] 802.3ad: use standard ethhdr instead of ad_header

802.3ad has its own ethhdr-like structure in the form of an ad_header,
which is at the start of both the LACPDU and marker PDU.  Both are
the same from the struct values, both are packed as well.

It's therefore perfectly fine to replace the ad_header by the ethhdr
and to remove its definition.

Subject: [PATCH 1423/1429] sfc: SFT9001: Add cable diagnostics

The SFT9001 firmware implements cable diagnostics; run those and
include their results in a self-test.  In case of a cable fault, do
not fail the self-test as a whole; only faults in the NIC should cause
that.

Subject: [PATCH 1426/1429] gro: Fix potential use after free

The initial skb may have been freed after napi_gro_complete in
napi_gro_receive if it was merged into an existing packet.  Thus
we cannot check same_flow (which indicates whether it was merged)
after calling napi_gro_complete.

This patch fixes this by saving the same_flow status before the
call to napi_gro_complete.

Subject: [PATCH 1427/1429] net: Fix warning fallout from recent NAPI interface
 changes.

When we removed the network device argument from several
NAPI interfaces in 908a7a16b852ffd618a9127be8d62432182d81b4
("net: Remove unused netdev arg from some NAPI interfaces.")
several drivers now started getting unused variable warnings.

This fixes those up.

Subject: [PATCH 1429/1429] net: Allow dependancies of FDDI & Tokenring to be
 modular.

I noticed it isn't possible to build token ring & fddi drivers
without causing LLC, and a bunch of other things to be forced
built-in.  For distro kernels, this means carrying a chunk of
code in the vmlinuz, even if the user doesn't use those protocols.
