The cleanup sequence in sky2_probe() that is called in case of an error is
mixed up in different places:
- pci_disable_device() is not called in each case the device has been enabled
before
- same for pci_disable_msi(): test_msi() may return with an error != EOPNOTSUPP
(due to failure of request_irq()). In that case msi is not disabled
- also failure of register_netdev() does not disable msi
This patch fixes the concerning parts.

On the RF3290,RF5360,RF5370,RF5372,RF5390,RF5392
radio frontends, the VCO calibration can be
controlled via the RFCSR3 register. The current
code uses the RFCSR30_RF_CALIBRATION constant to
enable the calibration, however that belongs to
the RFCSR30 register. Although the values of the
constant is correct, but using that for another
register is confusing.
Add a new definition for the VCO calibration enable
bit of the RFCSR3 register and use that in the
relevant places in order to avoid confusions.

On A-MPDU frames, the hardware only reports valid
signal strength data for the last subframe.
This patch fixes it by flagging everything but the
last subframe in an A-MPDU to tell mac80211 to
ignore the signal strength entirely. Otherwise
the empty value (= 0 dbm) will distort the
average quite badly.

The 8139cp driver has a change_mtu function that has not been
enabled since the dawn of the git repository. However, the
generic eth_change_mtu is not used in its place, so that
invalid MTU values can be set on the interface.
Original patch salvages the broken code for the single case of
setting the MTU while the interface is down, which is safe
and also includes the range check. Now enhanced to support up
or down interface.

We attach queue 0 after registering netdevice currently. This leads to call

allow tun/tap has a maximum of 1024 queues, this may lead a huge number of

remove 2046. Solve this problem by attaching queue 0 and set the real number of

efx_mcdi_poll() uses get_seconds() to read the current time and to
implement a polling timeout. The use of this function was chosen
partly because it could easily be replaced in a co-sim environment
with a macro that read the simulated time.
Unfortunately the real get_seconds() returns the system time (real
time) which is subject to adjustment by e.g. ntpd. If the system time
is adjusted forward during a polled MCDI operation, the effective
timeout can be shorter than the intended 10 seconds, resulting in a
spurious failure. It is also possible for a backward adjustment to
delay detection of a areal failure.
Use jiffies instead, and change MCDI_RPC_TIMEOUT to be denominated in
jiffies. Also correct rounding of the timeout: check time > finish
(or rather time_after(time, finish)) and not time >= finish.

efx_writed_table() uses a step of 16 bytes but efx_readd_table() uses
a step of 4 bytes. Why are they different?
Firstly, register access is asymmetric:
- The EVQ_RPTR table and RX_INDIRECTION_TBL can (or must?) be written
as dwords even though they have a step size of 16 bytes, unlike
most other CSRs.
- In general, a read of any width is valid for registers, so long as
it does not cross register boundaries. There is also no latching
behaviour in the BIU, contrary to rumour.
We write to the EVQ_RPTR table with efx_writed_table() but never read
it back as it's write-only. We write to the RX_INDIRECTION_TBL with
efx_writed_table(), but only read it back for the register dump, where
we use efx_reado_table() as for any other table with step size of 16.
We read MC_TREG_SMEM with efx_readd_table() for the register dump, but
normally read and write it with efx_readd() and efx_writed() using
offsets calculated in bytes.
Since these functions are trivial and have few callers, it's clearer
to open-code them at the call sites. While we're at it, update the
comments on the BIU behaviour again.

Receiving pause frames can block TX queue flushes. Earlier changes
work around this by reconfiguring the MAC during flushes for VFs, but

There are 2 different things:
- sub-menu for "Atheros Wireless cards" family
- module ath.ko with common Atheros code
Until now, they both used to depend on the same Kconfig variable ATH_COMMON.
Thus, being "Atheros card" and "depending on ath.ko" was the same.
To allow module to belong to the
"Atheros Wireless cards" family but not use ath.ko,
2 conditions above need to be separated.
So, this patch introduce new Kconfig variable ATH_CARDS for belonging
to the "Atheros Wireless Cards" family; while ATH_COMMON becomes hidden
variable to express dependency on common Atheros code in ath.ko. Modules
that depend on this common code now express it by setting ATH_COMMON.
Right now, ath6kl do not depend on common code and thus do not set ATH_COMMON.

Bonding in balance-alb mode records information from ARP packets
passing through the bond in a hash table (rx_hashtbl).
At certain situations (e.g. link change of a slave),
rlb_update_rx_clients() will send out ARP packets to update ARP
caches of other hosts on the network to achieve RX load
balancing.
The problem is that once an IP address is recorded in the hash
table, it stays there indefinitely. If this IP address is
migrated to a different host in the network, bonding still sends
out ARP packets that poison other systems' ARP caches with
invalid information.
This patch solves this by looking at all incoming ARP packets,
and checking if the source IP address is one of the source
addresses stored in the rx_hashtbl. If it is, but the MAC
addresses differ, the corresponding hash table entries are
removed. Thus, when an IP address is migrated, the first ARP
broadcast by its new owner will purge the offending entries of
rx_hashtbl.
The hash table is hashed by ip_dst. To be able to do the above
check efficiently (not walking the whole hash table), we need a
reverse mapping (by ip_src).
I added three new members in struct rlb_client_info:
rx_hashtbl[x].src_first will point to the start of a list of
entries for which hash(ip_src) == x.
The list is linked with src_next and src_prev.
When an incoming ARP packet arrives at rlb_arp_recv()
rlb_purge_src_ip() can quickly walk only the entries on the
corresponding lists, i.e. the entries that are likely to contain
the offending IP address.
To avoid confusion, I renamed these existing fields of struct
rlb_client_info:
next -> used_next
prev -> used_prev
rx_hashtbl_head -> rx_hashtbl_used_head
(The current linked list is _not_ a list of hash table
entries with colliding ip_dst. It's a list of entries that are
being used; its purpose is to avoid walking the whole hash table
when looking for used entries.)

Do not modify or load balance ARP packets passing through balance-alb
mode (wherein the ARP did not originate locally, and arrived via a bridge).
Modifying pass-through ARP replies causes an incorrect MAC address
to be placed into the ARP packet, rendering peers unable to communicate
with the actual destination from which the ARP reply originated.
Load balancing pass-through ARP requests causes an entry to be
created for the peer in the rlb table, and bond_alb_monitor will
occasionally issue ARP updates to all peers in the table instrucing them
as to which MAC address they should communicate with; this occurs when
some event sets rx_ntt. In the bridged case, however, the MAC address
used for the update would be the MAC of the slave, not the actual source
MAC of the originating destination. This would render peers unable to
communicate with the destinations beyond the bridge.

First I would give three observations which will be used later.
Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq)
This usage is wrong because the pending bit is cleared just before the
work's fn is executed and if the function re-arms itself we might end up
with the work still running. It's safe to call cancel_delayed_work_sync()
even if the work is not queued at all.
Observation 2: Use of INIT_DELAYED_WORK()
Work needs to be initialized only once prior to (de/en)queueing.
Observation 3: IFF_UP is set only after ndo_open is called
Related race conditions:
1. Race between bonding_store_miimon() and bonding_store_arp_interval()
Because of Obs.1 we can end up having both works enqueued.
2. Multiple races with INIT_DELAYED_WORK()
Since the works are not protected by anything between INIT_DELAYED_WORK()
and calls to (en/de)queue it is possible for races between the following
functions:
(races are also possible between the calls to INIT_DELAYED_WORK()
and workqueue code)
bonding_store_miimon() - bonding_store_arp_interval(), bond_close(),
bond_open(), enqueued functions
bonding_store_arp_interval() - bonding_store_miimon(), bond_close(),
bond_open(), enqueued functions
3. By Obs.1 we need to change bond_cancel_all()
Bugs 1 and 2 are fixed by moving all work initializations in bond_open
which by Obs. 2 and Obs. 3 and the fact that we make sure that all works
are cancelled in bond_close(), is guaranteed not to have any work
enqueued.
Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so
they can't race with bond_close and bond_open. The opposing work is
cancelled only if the IFF_UP flag is set and it is cancelled
unconditionally. The opposing work is already cancelled if the interface
is down so no need to cancel it again. This way we don't need new
synchronizations for the bonding workqueue. These bugs (and fixes) are
tied together and belong in the same patch.
Note: I have left 1 line intentionally over 80 characters (84) because I
didn't like how it looks broken down. If you'd prefer it otherwise,
then simply break it.

====================
This pull request is intended for the 3.8 stream. It is a bit large
-- I guess Thanksgiving got me off track! At least the code got to
spend some time in linux-next... :-)
This includes the usual batch of pulls for Bluetooth, NFC, and mac80211
as well as iwlwifi. Also here is an ath6kl pull, and a new driver
in the rtlwifi family. The brcmfmac, brcmsmac, ath9k, and mwl8k get
their usual levels of attention, and a handful of other updates tag
along as well.
For more detail on the pulls, please see below...
On Bluetooth, Gustavo says:
"Another set of patches for integration in wireless-next. There are two big set
of changes in it: Andrei Emeltchenko and Mat Martineau added more patches
towards a full Bluetooth High Speed support and Johan Hedberg improve the
single mode support for Bluetooth dongles. Apart from that we have small fixes
and improvements."
...and:
"A few patches to 3.8. The majority of the work here is from Andrei on the High
Speed support. Other than that Johan added support for setting LE advertising
data. The rest are fixes and clean ups and small improvements like support for
a new broadcom hardware."
On mac80211, Johannes says:
"This is for mac80211, for -next (3.8). Plenty of changes, as you can see
below. Some fixes for previous changes like the export.h include, the
beacon listener fix from Ben Greear, etc. Overall, no exciting new
features, though hwsim does gain channel context support for people to
try it out and look at."
...and...:
"This one contains the mac80211-next material. Apart from a few small new
features and cleanups I have two fixes for the channel context code. The
RX_END timestamp support will probably be reworked again as Simon Barber
noted the calculations weren't really valid, but the discussions there
are still going on and it's better than what we had before."
...and:
"Please pull (see below) to get the following changes:
* a fix & a debug aid in IBSS from Antonio,
* mesh cleanups from Marco,
* a few bugfixes for some of my previous patches from Arend and myself,
* and the big initial VHT support patchset"
And on iwlwifi, Johannes says:
"In addition to the previous four patches that I'm not resending,
we have a number of cleanups, message reduction, firmware error
handling improvements (yes yes... we need to fix them instead)
and various other small things all over."
...and:
"In his quest to try to understand the current iwlwifi problems (like
stuck queues etc.) Emmanuel has first cleaned up the PCIe code, I'm
including his changes in this pull request. Other than that I only have
a small cleanup from Sachin Kamat to remove a duplicate include and a
bugfix to turn off MFP if software crypto is enabled, but this isn't
really interesting as MFP isn't supported right now anyway."
On NFC, Samuel says:
"With this one we have:
- A few HCI improvements in preparation for an upcoming HCI chipset support.
- A pn544 code cleanup after the old driver was removed.
- An LLCP improvement for notifying user space when one peer stops ACKing I
frames."
On ath6kl, Kalle says:
"Major changes this time are firmware recover support to gracefully
handle if firmware crashes, support for changing regulatory domain and
support for new ar6004 hardware revision 1.4. Otherwise there are just
smaller fixes or cleanups from different people."
Thats about it... :-) Please let me know if there are problems!

If all slaves of a balance-rr bond with ARP monitor are enslaved
with down link state, bond keeps down state even after slaves
go up.
This is caused by bond_enslave() setting curr_active_slave to
first slave not taking into account its link state. As
bond_loadbalance_arp_mon() uses curr_active_slave to identify
whether slave's down->up transition should update bond's link
state, bond stays down even if slaves are up (until first slave
goes from up to down at least once).
Before commit f31c7937 "bonding: start slaves with link down for
ARP monitor", this was masked by slaves always starting in UP
state with ARP monitor (and MII monitor not relying on
curr_active_slave being NULL if there is no slave up).

Per measurements, the SFP+ suffered from small current leakage in two cases:
- When no module was plugged and TX laser was disabled. The fix was to enable
it, and when module is plugged in, check if it needs to be disabled.
- When over-current event occurs due to invalid SFP+ module, the HW basically
shuts down the current for this module, but the SW needs to complete this
by issuing a power down via a GPIO.

When drivers works on top of an old bootcode, it is theoretically subjected to
MDC/MDIO failures since the MDIO clock is set in the beginning of each sequence,
rather than per CL45 command. On rare cases an old bootcodes may change that in
the middle, so to address that, the MDIO clock is set for each CL45 access.
In addition, setting the MDIO clock is now done per EMAC base, and
not per port number, since a specific port can potentially use both EMACs for
different PHY accesses.

The XOFF received statistic registers are per priority based and not per
traffic class. The ixgbe driver was incorrectly considering them to be for
each traffic class; and then disabling the "Tx hang" check for the queues
that belonged to the particular traffic class that had received PFC frames.
The above logic worked fine in scenario where the user priority and traffic
class number matched e.g. priority 0 is mapped to traffic class 0 and so on.
But, when multiple user priorities are mapped to a single traffic class or
when user priorities and traffic class numbers do not line up; the ixgbe
driver may disable the "Tx hang" check for queues belonging to a traffic
class that did not receive PFC frames and keep the "Tx hang" check enabled
for the queues that did receive the PFC frames.
This patch corrects the above in the code by considering the statistics
on a per priority basis; then getting the traffic class the user priority
belongs to and disabling the "Tx hang" check for queues that belong
to that traffic class.

It's not very useful to make either the DSA core or the tagging

1. Define a hidden HAVE_NET_DSA option and move the dependencies of
NET_DSA to that. While we're at it, drop the deprecated

2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA.

ConnectX-3 devices can use either 64- or 32-byte completion queue
entries (CQEs) and event queue entries (EQEs). Using 64-byte
EQEs/CQEs performs better because each entry is aligned to a complete
cacheline. This patch queries the HCA's capabilities, and if it
supports 64-byte CQEs and EQES the driver will configure the HW to
work in 64-byte mode.
The 32-byte vs 64-byte mode is global per HCA and not per CQ or EQ.
Since this mode is global, userspace (libmlx4) must be updated to work
with the configured CQE size, and guests using SR-IOV virtual
functions need to know both EQE and CQE size.
In case one of the 64-byte CQE/EQE capabilities is activated, the
patch makes sure that older guest drivers that use the QUERY_DEV_FUNC
command (e.g as done in mlx4_core of Linux 3.3..3.6) will notice that
they need an update to be able to work with the PPF. This is done by
changing the returned pf_context_behaviour not to be zero any more. In
case none of these capabilities is activated that value remains zero
and older guest drivers can run OK.
The SRIOV related flow is as follows
1. the PPF does the detection of the new capabilities using
QUERY_DEV_CAP command.
2. the PPF activates the new capabilities using INIT_HCA.
3. the VF detects if the PPF activated the capabilities using
QUERY_HCA, and if this is the case activates them for itself too.
Note that the VF detects that it must be aware to the new PF behaviour
using QUERY_FUNC_CAP. Steps 1 and 2 apply also for native mode.
User space notification is done through a new field introduced in
struct mlx4_ib_ucontext which holds device capabilities for which user
space must take action. This changes the binary interface so the ABI
towards libmlx4 exposed through uverbs is bumped from 3 to 4 but only
when **needed** i.e. only when the driver does use 64-byte CQEs or
future device capabilities which must be in sync by user space. This
practice allows to work with unmodified libmlx4 on older devices (e.g
A0, B0) which don't support 64-byte CQEs.
In order to keep existing systems functional when they update to a
newer kernel that contains these changes in VF and userspace ABI, a
module parameter enable_64b_cqe_eqe must be set to enable 64-byte
mode; the default is currently false.

Change nl80211 to support specifying a VHT (or HT)
using the control channel frequency (as before) and
new attributes for the channel width and first and
second center frequency. The old channel type is of
course still supported for HT.
Also change the cfg80211 channel definition struct
to support these by adding the relevant fields to
it (and removing the _type field.)
This also adds new helper functions:
- cfg80211_chandef_create to create a channel def
struct given the control channel and channel type,
- cfg80211_chandef_identical to check if two channel
definitions are identical
- cfg80211_chandef_compatible to check if the given
channel definitions are compatible, and return the
wider of the two
This isn't entirely complete, but that doesn't matter
until we have a driver using it. In particular, it's
missing
- regulatory checks on the usable bandwidth (if that
even makes sense)
- regulatory TX power (database can't deal with it)
- a proper channel compatibility calculation for the
new channel types
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.
Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.
