Matan Barak 4de6580360 mlx4_core: Add support for steerable IB UD QPs
This patch adds support for allocating IB UD QPs that we can steer
traffic from.  We introduce a new firmware command FLOW_STEERING_IB_UC_QP_RANGE
and a capability bit.

This command isn't supported for VFs.

Bjørn Mork fdc3452cd2 net: usbnet: fix SG initialisation
Commit 60e453a940 ("USBNET: fix handling padding packet")
added an extra SG entry in case padding is necessary, but
failed to update the initialisation of the list. This can
cause list traversal to fall off the end of the list,
resulting in an oops.

Sergei Shtylyov 090d560fc4 sh_eth: fix garbled TX error message
sh_eth_error() in case of a TX error tries to print a message using 2 dev_err()
calls with the first string not finished by '\n', so that the resulting message
would inevitably come out garbled, with something like "3net eth0: " inserted
in the middle.  Avoid that by merging 2 calls into one.

While at it, insert an empty line after the nearby declaration.

Veaceslav Falico 49b7624eda bonding: fix __get_active_agg() RCU logic
Currently, the implementation is meaningless - once again, we take the
slave structure and use it after we've exited RCU critical section.

Fix this by removing the rcu_read_lock() from __get_active_agg(), and
ensuring that all its callers are holding RCU.

Veaceslav Falico 768b954922 bonding: fix __get_first_agg RCU usage
Currently, the RCU read lock usage is just wrong - it gets the slave struct
under RCU and continues to use it when RCU lock is released.

However, it's still safe to do this cause we didn't need the
rcu_read_lock() initially - all of the __get_first_agg() callers are either
holding RCU read lock or the RTNL lock, so that we can't sync while in it.

Veaceslav Falico c1bc9644ec bonding: fix bond_3ad_set_carrier() RCU usage
Currently, its usage is just plainly wrong. It first gets a slave under
RCU, and, after releasing the RCU lock, continues to use it - whilst it can
be freed.

Fix this by ensuring that bond_3ad_set_carrier() holds RCU till it uses its
slave (or its agg).

Enabling the oscillator consumes slightly more power (100uA)
but allows to make sure that we exit from L1 on time.

Not doing so might lead to a PCIe specification violation

This issue has been identified on 3160 and 7260 only.
On older NICs L1 off is not enabled, on newer NICs (7265),
the issue is fixed.

When the bug occurs the user sees that the NIC has
disappeared from the PCI bridge, any access to the device
returns 0xff.

Sujith Manoharan 071aa9a8b2 ath9k: Process GTT interrupts
Global Transmission Timeout interrupts are generated by
the HW when transmission of a frame fails - this is done
based on the threshold programmed in the AR_GTXTO register.

Currently, even though the interrupt is enabled for all chips,
it is not handled in the driver. This patch handles GTT events
for AR9003 and above chips, checking if the MAC/BB has hung
after successive GTT interrupts crosses a threshold (5).

This can be enabled for the older chips in the AR9002 family once
appropriate HW hang checks are implemented for them.

In https://bugzilla.kernel.org/show_bug.cgi?id=67561, a locking dependency is reported
when b43 is used with hostapd, and rfkill is used to kill the radio output.

The lockdep splat (in part) is as follows:

======================================================
[ INFO: possible circular locking dependency detected ]
3.12.0 #1 Not tainted
-------------------------------------------------------
rfkill/10040 is trying to acquire lock:
 (rtnl_mutex){+.+.+.}, at: [<ffffffff8146f282>] rtnl_lock+0x12/0x20

but task is already holding lock:
 (rfkill_global_mutex){+.+.+.}, at: [<ffffffffa04832ca>] rfkill_fop_write+0x6a/0x170 [rfkill]

--snip--

Chain exists of:
  rtnl_mutex --> misc_mtx --> rfkill_global_mutex

The fix is to move the initialization of the hardware random number generator
outside the code range covered by the rtnl_mutex.

Luis R. Rodriguez 4f7b91404c cfg80211: make regulatory_hint() remove REGULATORY_CUSTOM_REG
The REGULATORY_CUSTOM_REG can be used during early init with
the goal of overriding the wiphy's default regulatory settings
in case the alpha2 of the device is not known. In the case that
the alpha2 becomes known lets avoid having drivers having to
clear the REGULATORY_CUSTOM_REG flag by doing it for them
when regulatory_hint() is used.

Luis R. Rodriguez 8fc685803a ath: fix warning on usage of REGULATORY_CUSTOM_REG
ath wants to first apply the custom regd and only later
will it revert to not using it if an alpha2 regulatory
domain is found. Since the wireless core now enforces
usage of the REGULATORY_CUSTOM_REG strictly when
wiphy_apply_custom_regulatory() is used this makes
ath adhere to the expected behaviour but also updates
the wiphy after its done with the custom usage.

This fixes this warning:

In order to use the native GRO handling of encapsulated protocols on

unless busy polling is in action.

While we are at it, rename mlx4_en_cq_ll_polling() to
mlx4_en_cq_busy_polling()

Emmanuel Grumbach 2775613f4f iwlwifi: mvm: don't set the drain bit when we flush the AP station
When we disassociate in managed mode, we flush the queues
after mac80211 has already removed the station.
During that time, the pointer to ieee80211_sta to the
fw_id_to_mac_id map is -EINVAL. In that case we should not
set the station as being drained when the last Tx of this
station has exited the shared Tx queue since we are
flushing all the queues anyway.
The draining logic is meant to be used in GO / AP mode only.
In GO / AP mode, we set -EBUSY in the fw_id_to_mac_id map.

This is why testing the ieee80211_sta pointer in the
fw_id_to_mac_id map with IS_ERR isn't enough to set the
station as draining, we need to check that it is -EBUSY.

The only impact of the bug was a print:

Drained sta 1, but it is internal?

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e and now i40evf.

Most notable is Jacob's patch to add PTP support to i40e.

Mitch cleans up additional memcpy's and use struct assignment instead.
Then fixes long lines to appease checkpatch.pl.  Mitch then provides
a fix to keep us from spamming the log with confusing errors.  If you
use ip to change the MAC address of a VF while the VF driver is loaded,
closing the VF interface or unloading the VF driver will cause the VF
driver to remove the MAC filter for its original (now invalid) MAC
address.

Jesse cleans up macros which are no longer needed or used.

I (Jeff) cleanup function header comments to ensure Doxygen/kdoc works
correctly to generate documentation without warnings.

Anjali fixes a bug where ethtool set-channels would return failure when
configuring only one Rx queue.  Then fixes a bug where the driver was
erroneously exiting the driver unload path if one part of the unload
failed.

Shannon fixes if the IPV6EXADD but is set in the Rx descriptor status,
there was an optional extension header with an alternate IP address
detected and the hardware checksum was not handling the alternate IP
address correctly.  Then adjusts the ITR max and min values to match
the hardware max value and recommended min value.  Shannon makes sure
to clear the PXE mode after the adminq is initialized.

v2:
 - fix patch 14 "i40e: enable PTP" to address Richard Cochran's spelling
   catch and Ben Hutchings Kconfig, SIOCGHWTSTAMP and sizeof() suggestions
 - added Paul Gortmaker's i40evf fix patch
v3:
 - fix patch 14 "i40e: enable PTP" to address Ben Hutchings concerns about
   a race with PTP init and cleanup and i40e_get_ts_info().

Mitch Williams 700bbf6c1f i40e: allow VF to remove any MAC filter
If you use ip to change the MAC address of a VF while the VF
driver is loaded, closing the VF interface or unloading the VF
driver will cause the VF driver to remove the MAC filter for its
original (now invalid) MAC address. This would cause the PF
driver to kick an error message to the log, and back to the VF
driver.

Since the VF driver has not really done anything naughty, let's
not punish it. Don't check for MAC address overrides on the
delete operation, just make sure it's a valid address. This keeps
us from spamming the log with confusing errors.

Jason Wang f663dd9aaf net: core: explicitly select a txq before doing l2 forwarding
Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:

- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
  instead of lower device which misses the necessary txq synchronization for
  lower device such as txq stopping or frozen required by dev watchdog or
  control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
  watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
  when tso is disabled for lower device.

Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.

With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.

In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.

bnx2x triggers warnings with CONFIG_DMA_API_DEBUG=y:

  WARNING: CPU: 0 PID: 2253 at lib/dma-debug.c:887 check_unmap+0xf8/0x920()

  different size [device address=0x00000000da2b389e] [map size=1490 bytes]
  [unmap size=66 bytes]

The reason is that bnx2x splits a TSO BD into two BDs (headers + data)
using one DMA mapping for both, but it uses only the length of the first
BD when unmapping.

This patch fixes the bug by unmapping the whole length of the two BDs.

Paul Durrant 11b57f9025 xen-netback: stop vif thread spinning if frontend is unresponsive
The recent patch to improve guest receive side flow control (ca2f09f2) had a
slight flaw in the wait condition for the vif thread in that any remaining
skbs in the guest receive side netback internal queue would prevent the
thread from sleeping. An unresponsive frontend can lead to a permanently
non-empty internal queue and thus the thread will spin. In this case the
thread should really sleep until the frontend becomes responsive again.

This patch adds an extra flag to the vif which is set if the shared ring
is full and cleared when skbs are drained into the shared ring. Thus,
if the thread runs, finds the shared ring full and can make no progress the
flag remains set. If the flag remains set then the thread will sleep,
regardless of a non-empty queue, until the next event from the frontend.

Use hardware capabilities to limit IRQ generation to about 15 per msec
It corresponds to about 7 packets/IRQ when running iperf with default

Do not enable this feature in the sniffer (monitor)  mode, because
interrupt moderation cause timestamp accuracy deterioration.

The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

David Gnedt 64322e28d3 wl1251: fix scan behaviour while not associated
With a dissasociated card I often encoutered very long scan delays.

My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.

Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

Eric Dumazet 8f646c922d vxlan: keep original skb ownership
Sathya Perla posted a patch trying to address following problem :

<quote>
 The vxlan driver sets itself as the socket owner for all the TX flows
 it encapsulates (using vxlan_set_owner()) and assigns it's own skb
 destructor. This causes all tunneled traffic to land up on only one TXQ
 as all encapsulated skbs refer to the vxlan socket and not the original
 socket.  Also, the vxlan skb destructor breaks some functionality for
 tunneled traffic like wmem accounting and as TCP small queues and
 FQ/pacing packet scheduler.
</quote>

I reworked Sathya patch and added some explanations.

vxlan_xmit() can avoid one skb_clone()/dev_kfree_skb() pair
and gain better drop monitor accuracy, by calling kfree_skb() when
appropriate.

The UDP socket used by vxlan to perform encapsulation of xmit packets
do not need to be alive while packets leave vxlan code. Its better
to keep original socket ownership to get proper feedback from qdisc and
NIC layers.

We use skb->sk to

A) control amount of bytes/packets queued on behalf of a socket, but
prior vxlan code did the skb->sk transfert without any limit/control
on vxlan socket sk_sndbuf.

B) security purposes (as selinux) or netfilter uses, and I do not think
anything is prepared to handle vxlan stacked case in this area.

By not changing ownership, vxlan tunnels behave like other tunnels.
As Stephen mentioned, we might do the same change in L2TP.

Dan Williams e5e97ee956 hso: fix handling of modem port SERIAL_STATE notifications
The existing serial state notification handling expected older Option
devices, having a hardcoded assumption that the Modem port was always
USB interface #2.  That isn't true for devices from the past few years.

hso_serial_state_notification is a local cache of a USB Communications
Interface Class SERIAL_STATE notification from the device, and the
USB CDC specification (section 6.3, table 67 "Class-Specific Notifications")
defines wIndex as the USB interface the event applies to.  For hso
devices this will always be the Modem port, as the Modem port is the
only port which is set up to receive them by the driver.

So instead of always expecting USB interface #2, instead validate the
notification with the actual USB interface number of the Modem port.

Mitch Williams 7efa84b7ab i40e: support VFs on PFs other than 0
When communicating with VF devices over the AQ, the FW refers to the
VF by its global VF ID, not local the VF ID with reference to its
parent PF. Since the global and local VF IDs are identical for PF 0,
the code worked correctly on PF 0.

However, we cannot just use global IDs throughout the code as most of
the other references to the VF (VSI setup, register offsets, etc.)
require the local VF ID. Instead, we just add or subtract our base VF
ID when sending and receiving AQ messages.

Greg Rose 567472640c i40e: Do not enable default port on the VEB
Enabling the default port on the VEB causes all outgoing traffic from
virtual functions to be copied to the physical function.  The default
port is only supposed to be used if you wish to bridge the physical
function to a SW switch such as Open vSwitch or the Linux bridge. That
allows the SW switch to route traffic to VMs that are not using a
virtual function.

Eventually we'll want to implement the ndo_fdb_add, ndo_fdb_del, and
ndo_fdb_dump functions.  The ndo_fdb_add function would set the
default port on the VEB in those cases where the MAC/VLAN address
filters have overflowed.  Normally we would not want to use it.

If the hypervisor configures a vlan for the VF via the PF, the expected
result is that only packets tagged by said vlan will be received by the VF

Due to an incorrect manipulation of vlan filters in the driver, the

of the smaller struct, possibly causing the flow utilizing the larger

The allocation and clearing of rings for a VSI should be
using the alloc_queue_pairs and not num_queue_pairs.

The alloc_queue_pairs per VSI is a pre-allocated number
of queues assigned to a VSI; based on number of TCs enabled
only certain number of queues may be used from that. This
is mainly valid only for the LAN VSI case as that is the
only VSI that may be enabled with multiple traffic classes.
In the future the number of TCs may change based on DCBX
configuration.

The actual number of queues that are enabled/configured is
based on the number of TCs enabled for a given VSI and that
is stored in num_queue_pairs.

With this change num_[tr]x_queues is unused so remove them.

the pf->vsi array fails.  This was causing a kernel BUG because the
call to i40e_clear_interrupt_scheme() was assuming the pf->vsi[] array
existed.  In this fix it is possible that i40e_reset_interrupt_capability()
will get called twice, but this is a safe action.

Mitch Williams 6c1b5bff5a i40e: guard against vf message races
When disabling and enabling VFs on a live system with the VF driver
loaded, it's possible to receive an admin queue message from the VF
driver at an inconvenient time, e.g. when the associated data structures
aren't present or configured. This causes a rather inconvenient panic.

To guard against this, we change the order of when we set num_alloc_vfs
when turning off SR-IOV, and then gate processing of any VF messages
based upon that value. Likewise, when enabling VFs, we shut off the
relevant interrupt until configuration is complete.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e and pci_regs.h.

Anjali provides a patch to prevent messages from stray HMC events, except
at interrupt message level, and refactors the HMC error handling.

Catherine adds routines in probe to populate/check PCI bus speed and width,
then verify we are in a 8GT/s x8 PCIe slot and warn when we are not.

Shannon adds Wake-on-LAN support for i40e, fixes curly brace use as well as
return type for i40e_vsi_clear_rings().

Joseph implements receive offload for VXLAN for i40e, where the hardware
supports checksum offload/verification of the inner/outer header.

Mitch provides the bulk of the changes, where he refactors the VF reset
code so that it works on real hardware.  Then does code cleanup by
calling existing functions to enable and disable queues for VFs and
remove unused functions.  Removes a unnecessary log messages that are
seen at every VF reset, for example complaining about disabling queues
that are already disabled.  Fixes an error return when the VF asks to
add an invalid MAC address and if the VF sends a bad message, make it
more informative about what is actually going on.

Jesse refactors the LED function to flash LED lights correctly.

v2:
 - removed patch 5 "i40e: add set settings and pauseparam" based on
   feedback from Ben Hutchings, will re-work that patch for later
   submission
 - Added patch "i40e: Implementation of vxlan ndo's" from Joseph to
   address Or Gerlitz's questions and concerns.  This patch adds the
   implementation for the VXLAN ndo's and allows the hardware to do
   receive checksum offload for inner packets on the UDP ports that
   VXLAN notifies us about.
 - Added patch "i40e: using for_each_set_bit to simplify the code"
   from Wei Yongjun.  This patch uses for_each_set_bit() to simply
   the code.

v3:
 - fixed indentation issue in patch 11 based on feedback from
   Sergei Shtylyov.

Sorry for the delayed release of v4, it was delayed to the holidays.

v4:
 - Addressed Or Gerlitz's concerns about trying to get a hold of a mutex
   while holding a spin lock in patch 6 by executing the AQ commands from
   a subtask.
 - Addressed David Miller's Kconfig concerns by creating a Kconfig VXLAN
   option for i40e and wrapped appropriate code with the config option in
   patch 6.
 - Updated patch 7 based on the changes made in patch 6 in the above two
   bullets.

v5:
 - Added the patch to pci_regs.h based on David Miller's feedback to add
   PCI defines for speed and width
 - Updated patch 3 description to better explain the changes based on
   feedback from David Miller
 - Updated patch 4 to use the newly added defines to pci_regs.h instead
   of local defines
 - Updated patch 7 to use <net/vxlan.h> in the #include based on feedback
   from David Miller

Fix the VF reset flow so that it works on real hardware. After

somewhat.

- Change the i40e_reset_vf function to a void type, and fix

- Move the MSI-X disable code to i40e_free_vf_res since it must
  be done every time the VF is freed, regardless of whether or
  not it is reset.
- Ensure that the PCIe bus is quiet before polling the reset bit.
- Don't clear the VFGEN_RSTAT1 register at the beginning as it is
  cleared by the reset.
- Poll longer for the reset to be done.
- Disable the queues using an existing function rather than
  rolling our own.
- Free and reallocate the VSI after reset to avoid rx hang.

Shannon Nelson 8e2773ae35 i40e: add wake-on-lan support
Wake on LAN is disabled by default and will remain that way for most
platforms, but there is an NVM setting that allows vendors to enable it
for a port if they think they've provided the right power environment
for the device.  This patch adds code to check the NVM setting and enable
Magic Packet use if WoL is enabled for the port.

Since only Magic Packet is supported, there's not a lot of HW configuration
needed.

Anjali Singhai Jain 9c010ee0ea i40e: Suppress HMC error to Interrupt message level
The HMC error interrupt would generate an un-necessary message
"unhandled interrupt", causing extra log spam, in addition to causing
a reset that was not necessary.  Prevent this issue by handling the
HMC error case explicitly, and only reset if the interrupt was from
some of the other causes.

Nithin Sujir 1743b83c86 tg3: Poll cpmu link state on APE + ASF enabled devices
On ASF enabled devices where the mgmt firmware runs on the application
processing engine, there is a race between the tg3 driver processing a
link change event and the ASF firmware clearing the link changed bit in
the EMAC status register. This leads to link notifications to the driver
sometimes getting lost.

Poll the CPMU link state as a backup for the normal interrupt path
update if ASF is enabled.

Nithin Sujir f82995b65c tg3: Set the MAC clock to the fastest speed during boot code load
On the 5717, 5718 and 5719 devices, the bootcode runs slower when any
port doesn't have a link due to clock speed slowing down as part of the
link-aware feature. This leads to the driver timing out waiting for the
bootcode signature.

This patch overrides the clock policy to the highest frequency just before
reset and restores it after the bootcode is up.

Sergei Shtylyov 128296fc3f sh_eth: coding style fixes
Running 'scripts/checkpatch.pl' on the driver files gives numerous warnings:

- block comments using empty /* line;

- unneeded \ at end of lines;

- message string split across lines;

- use of __attribute__((aligned(n))) instead of __aligned(n) macro;

- use of __attribute__((packed)) instead of __packed macro.

Additionally, running 'scripts/checkpatch.pl --strict' gives more complaints:

- including the paragraph about writing to FSF into the heading comment;

- alignment not matching open paren;

- multiple assignments on one line;

- use of CamelCase names;

- missing {} on one of the *if* arms where another has them;

- spinlock definition without a comment.

While fixing these, also do some more style cleanups:

- remove useless () around expressions;

- add {} around multi-line *if* operator's arm;

- remove space before comma;

- add spaces after /* and before */;

- properly align continuation lines of broken up expressions;

- realign comments to the structure fields.

Thadeu Lima de Souza Cascardo 940d9d34a5 cxgb4: allow large buffer size to have page size
Since commit 52367a763d
("cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support"),
we have failures like this during cxgb4 probe:

cxgb4 0000:01:00.4: bad SGE FL page buffer sizes [65536, 65536]
cxgb4: probe of 0000:01:00.4 failed with error -22

This happens whenever software parameters are used, without a
configuration file. That happens when the hardware was already
initialized (after kexec, or after csiostor is loaded).

It happens that these values are acceptable, rendering fl_pg_order equal
to 0, which is the case of a hard init when the page size is equal or
larger than 65536.

Accepting fl_large_pg equal to fl_small_pg solves the issue, and
shouldn't cause any trouble besides a possible performance reduction
when smaller pages are used. And that can be fixed by a configuration
file.

which is hardly nice. This patch fixes this by having each
PV driver check for:
 - if running in PV, then it is fine to execute (as that is their
   native environment).
 - if running in HVM, check if user wanted 'xen_emul_unplug=never',
   in which case bail out and don't load any PV drivers.
 - if running in HVM, and if PCI device 5853:0001 (xen_platform_pci)
   does not exist, then bail out and not load PV drivers.
 - (v2) if running in HVM, and if the user wanted 'xen_emul_unplug=ide-disks',
   then bail out for all PV devices _except_ the block one.
   Ditto for the network one ('nics').
 - (v2) if running in HVM, and if the user wanted 'xen_emul_unplug=unnecessary'
   then load block PV driver, and also setup the legacy IDE paths.
   In (v3) make it actually load PV drivers.

Shawn Bohrer 2156d9a8ac mlx4_en: Only cycle port if HW timestamp config changes
If the hwtstamp_config matches what is currently set for the device then
simply return.  Without this change any program that tries to enable
hardware timestamps will cause the link to cycle even if hardware
timstamps were already enabled.

Shawn Bohrer ad7d4eaed9 mlx4_en: Add PTP hardware clock
This adds a PHC to the mlx4_en driver. We use reader/writer spinlocks to
protect the timecounter since every packet received needs to call
timecounter_cycle2time() when timestamping is enabled.  This can become
a performance bottleneck with RSS and multiple receive queues if normal
spinlocks are used.

This driver has been tested with both Documentation/ptp/testptp and the
linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox
ConnectX-3 card.

Julia Lawall 769f01ef61 hamradio: 6pack: fix error return code
Set the return variable to an error code as done elsewhere in the function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

// </smpl>
