a80c7a6966 iwlwifi: mvm: constify the parameters of a few functions in fw-dbg.c
The debug functions of fw-dbg.c don't really need to modify
the trigger and the description they receive as a parameter.

This notification will be extended with extra data, so just

f5e28eac1a iwlwifi: mvm: check PN for CCMP/GCMP in the driver
As we're working on multi-queue RX, we want to parallelise checking
the PN in order to avoid having to serialise the RX processing.

It may seem that doing parallel PN checking is insecure, but it turns
out to be OK because queue assignment is done based on the data in the
frame (IP/TCP) and thus cannot be manipulated by an attacker, since
the data is encrypted and must first have been decrypted successfully.

There are some corner cases, in particular when the peer starts using
fragmentation which redirects the packet to the default queue. However
this redirection is remembered (for the STA, per TID) and thus cannot
be exploited by an attacker either.

Leave checking on the default queue (queue 0) to mac80211, since we
get fragmented packets there and those are subject to stricter checks
during reassembly.

bd6f5bd700 iwlwifi: mvm: don't ask beacons when P2P GO vif and no assoc sta
The commit below called iwl_mvm_mac_ctxt_changed() to handle
a case that the vif is a P2P GO.
However iwl_mvm_mac_ctxt_cmd_go() ignores the number of
associated stations and asks the FW to pass beacons anyways.

Fix this by checking ap_assoc_sta_count parameter, in iwl_mvm_mac_ctxt_cmd_go()
as well, and ask the FW to pass beacons only when there's
at least one associated station.

30433d3b98 iwlwifi: mvm: prevent multiple stations with the same address
As the device (and parts of the driver) cannot deal with having the
same MAC address for two stations (on two virtual interfaces), add
some explicit code to prevent this case.

Note that in practice this cannot happen since the device doesn't
support operating with two AP/GO interfaces at the same time either,
and other scenarios for this are, while not impossible, not going to
happen in practice.

a1cdb1c59c iwlwifi: dvm: fix WoWLAN
My commit below introduced a mutex in the transport to
prevent concurrent operations. To do so, it added a flag
(is_down) to make sure the transport is in the right state.
This uncoverred an bug that didn't cause any harm until
now: iwldvm calls stop_device and then starts the firmware
without calling start_hw in between. While this flow is
fine from the device configuration point of view (register,
etc...), it is now forbidden by the new is_down flag.
This led to this error to appear:
iwlwifi 0000:05:00.0: Can't start_fw since the HW hasn't been started
and the suspend would fail.

2ec7752fd9 wcn36xx: handle rx skb allocation failure to avoid system crash
Lawrence reported that git clone could make system crash on a
Qualcomm ARM soc based device (DragonBoard, 1G memory without
swap) running 64bit Debian.

It's turned out the crash is related with rx skb allocation
failure. git could consume more than 600MB anonymous memory.
And system is in extremely memory shortage case.

But driver didn't handle the rx allocation failure case. This patch
doesn't submit skb to upper layer if rx skb allocation fails.
Instead, it reuse the old skb for rx DMA again. It's more like
drop the packets if system is in memory shortage case.

With this change, git clone is OOMed instead of system crash.

which can trigger a crash recovery process. During
the process the platform can request a ram dump

recovery will start. This interface allows the platform

example to reset dependent subsystems in proper order, or

fde55c45d2 mkiss: fix scribble on freed memory
commit d79f16c046 fixed a user triggerable
scribble on free memory but added a new one which allows the user to
scribble even more and user controlled data into freed space.

As with 6pack we need to halt the queue before we free the buffers, because
the transmit logic is not protected by the semaphore.

c406700cdf ethernet/atheros/alx: sanitize buffer sizing and padding
This is based on the work done by Przemek Rudy in bug 70761 at
bugzilla.kernel.org, but with some work done to disentagle and clarify
things a bit.

Similar to Przemek's work and other drivers, we're adding a padding of 16
here, but we're also disentangling mtu size calculations from max buffer
size calculations a bit, and adding ETH_HLEN to the value written into
ALX_MTU. Hopefully, with a bit more consistency and clarity, things behave
better here. Sadly, I can only test in my alx-driven E2200, which worked
just fine before this patch.

In comment #58 of bug 70761, Eugene A. Shatokhin reports that this patch
does help considerably for a ROSA Linux user of his with an AR8162 network
adapter when patched into a 4.1.x-based kernel, with several days of
normal operation where wired network previously wasn't usable without
setting MTU to 9000 as a work-around.

60aa3b080a 6pack: fix free memory scribbles
commit acf673a318 fixed a user triggerable free
memory scribble but in doing so replaced it with a different one that allows
the user to control the data and scribble even more.

sixpack_close is called by the tty layer in tty context. The tty context is
protected by sp_get() and sp_put(). However network layer activity via
sp_xmit() is not protected this way. We must therefore stop the queue
otherwise the user gets to dump a buffer mostly of their choice into freed
kernel pages.

f0138e2596 mlxsw: pci: Adjust value of CPU egress traffic class
During initialization, when creating the send descriptor queues (SDQs),
we specify the CPU egress traffic class of each SDQ. The maximum number
of classes of this type is different in the two ASICs supported by this
PCI driver.

New firmware versions check this value is set correctly, which causes
errors on the Spectrum ASIC, as its max exposed egress traffic class is
lower than 7.

Solve this by setting this field to 3, which is an acceptable value for
both ASICs.

Note that we currently do not expose the QoS capabilities of the ASICs,
so setting this to an hardcoded value is OK for now.

drivers/built-in.o: In function `start':
binder.c:(.text+0x176078): undefined reference to `phy_start'

The reason is that the driver uses PHYLIB, but that is a loadable
module here, and fman itself is built-in.

This patch makes it possible to configure fman as a module as well
so we don't change the status of PHYLIB in an allmodconfig kernel,
and it adds a 'select PHYLIB' statement to ensure that phylib is
always built-in when fman is.

The driver uses "builtin_platform_driver(fman_driver);", which means
it cannot be unloaded, but it's still possible to have it as a loadable
module that gets loaded once and never removed.

4. If tx and rx rings use dedicated completion rings, then tx rings 0 to
m will be mapped to completion rings n + 1 to n + m.

5. Each tx or rx ring will use the corresponding completion ring index
for doorbell mapping and MSIX mapping.

b6ab4b01f5 bnxt_en: Separate bnxt_{rx|tx}_ring_info structs from bnxt_napi struct.
Currently, an rx and a tx ring are always paired with a completion ring.
We want to restructure it so that it is possible to have a dedicated
completion ring for tx or rx only.

The bnxt hardware uses a completion ring for rx and tx events.  The driver
has to process the completion ring entries sequentially for the rx and tx
events.  Using a dedicated completion ring for rx only or tx only has these
benefits:

1. A burst of rx packets can cause delay in processing tx events if the
completion ring is shared.  If tx queue is stopped by BQL, this can cause
delay in re-starting the tx queue.

2. A completion ring is sized according to the rx and tx ring size rounded
up to the nearest power of 2.  When the completion ring is shared, it is
sized by adding the rx and tx ring sizes and then rounded to the next power
of 2, often with a lot of wasted space.

3. Using dedicated completion ring, we can adjust the tx and rx coalescing
parameters independently for rx and tx.

The first step is to separate the rx and tx ring structures from the
bnxt_napi struct.

In this patch, an rx ring and a tx ring will point to the same bnxt_napi
struct to share the same completion ring.  No change in ring assignment
and mapping yet.

59869ebfe7 ieee802154: cc2520: Check CRC & add promiscuous
This patch adds checking the "CRC_OK" bit at the end of packets coming
from the CC2520 radio. It also adds support for putting the radio in
promiscuous mode (in which packets are not dropped if the CRC fails).
In promiscuous mode the AUTOCRC flag is cleared so that the driver can
pass the received CRC to the monitors.

The radio now defaults to frame filtering (checking that the destination
and PANID in the incoming packet matches the local node). This matches
the other 15.4 radios and is what a user would expect to be the default.

Other changes:

1. Adds LQI calculation
2. Makes #defines for relevant bit fields in CC2520 registers

10GbE Intel Wired LAN Driver Updates 2015-12-29

This series contains updates to ixgbe and ixgbevf.

William Dauchy provides a fix for ixgbevf that was implemented for ixgbe,
commit 5d6002b7b8 ("ixgbe: Fix handling of NAPI budget when multiple
queues are enabled per vector"). The issue was that the polling routine
would increase the budget for receive to at least 1 per queue if multiple
queues were present, which resulted in receive packets being processed
when the budget was 0.

Emil provides minor cleanups for ixgbevf, one being that we need to
check rx_itr_setting with == and not &, since it is not a mask.  Added
QSFP PHY support in ixgbe to allow for more accurate reporting of port
settings.  Fixed the max RSS limit for X550 which is 63, not 64.

Veola fixes ixgbe ethtool reporting of backplane type interfaces as
1000/10000baseT link modes, instead, report the media as KR, KX or KX4
based on the backplane interface present.

Mark cleans up redundancy in the setting of hw_enc_features that makes
it appear that X550 has more encapsulation features than other devices.
Also do not set NETIF_F_SG any longer since that is set by the
register_netdev() call.  Also fixed the X550EM_x revision check, which
needs to check a value, not just a bit.

Alex Duyck fixes additional bugs in ixgbe_clear_vf_vlans(), one being
that the mask was using a divide instead of a modulus, which resulted
in the mask bit being incorrectly set to 0 or 1 based on the value of
the VF being tested.  Alex also found that he was not consistent in
using the "word" argument as an offset or as a register offset, so
made the code consistently use word as the offset in the array.

v2: dropped patch 8 of the original series, as it was undoing a part of
    the fix Alex Duyck was doing in patch 9 of the original series.
    Dropped based on feedback from Emil (the author).

This patch removes support for FW-dump via --register-dump option as it is

"ethtool --register-dump" cmd which used to work earlier, will now fail
with ENOTSUPP error, we feel it is not an issue as this is used only

Commit 72ef3a88fa ("be2net: set pci_func_num while issuing

GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when
pf_num is zero. But, when pf_num is set to a non-zero value, FW does not
return the Port resource descriptor.
This patch fixes this by setting pf_num to 0 while issuing the query cmd
and adds code to pick the correct NIC resource descriptor from the list of
descriptors returned by FW.

d9d426af6b be2net: fix VF link state transition from disabled to auto
The VF link state setting transition from "disable" to "auto" does not work
due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not
be fixed in FW due to some backward compatibility issues it causes with
some released drivers. The issue has been fixed by introducing a new
version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link
state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1.

The VF link state setting feature now works on Lancer chips too from
FW ver 10.6.315.0 onwards.

f99551a2d3 rtlwifi: rtl_pci: Fix kernel panic
In commit 38506ecefa (rtlwifi: rtl_pci: Start modification for new
drivers), a bug was introduced that causes a NULL pointer dereference.
As this bug only affects the infrequently used RTL8192EE and only under
low-memory conditions, it has taken a long time for the bug to show up.

The bug was reported on the linux-wireless mailing list and also at
https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/ as
bug #1527603 (kernel crashes due to rtl8192ee driver on ubuntu 15.10).

ab3a3b7b0c ixgbe: Fix bugs in ixgbe_clear_vf_vlans()
When I had rewritten the code for ixgbe_clear_vf_vlans() it looks like I
had transitioned back and forth between using word as an offset and using
word as a register offset.  As a result I honestly don't see how the code
was working before other than the fact that resetting the VLANs on the VF
like didn't do much to clear them.

Another issue found is that the mask was using a divide instead of a
modulus.  As a result the mask bit was incorrectly being set to either bit
0 or 1 based on the value of the VF being tested.  As a result the wrong
VFs were having their VLANs cleared if they were enabled.

I have updated the code so that word represents the offset in the array.
This way we can use the modulus and xor operations and they will make sense
instead of being performed on a 4 byte aligned value.

I replaced the statement "(word % 2) ^ 1" with "~word % 2" in order to
reduce the line length as the line exceeded 80 characters with the register
name inserted.  The two should be equivalent so the change should be safe.

 "Three late 4.4-rc fixes.

  The first two were very small in terms of number of lines, the third
  is more lines of change than I like this late in the cycle, but there
  are positive test results from Avagotech and from my own test setup
  with the target hardware, and given the problem was a 100% failure
  case, I sent it through.

   - A previous patch updated the mlx4 driver to use vmalloc when there
     was not enough memory to get a contiguous region large enough for
     our needs, so we need kvfree() whenever we free that item.  We
     missed one place, so fix that now.

   - A previous patch added code to match incoming packets against a

f41647ef06 RDMA/be2net: Remove open and close entry points
Recently Dough Ledford reported a deadlock happening
between ocrdma-load sequence and NetworkManager service
issueing "open" on be2net interface.

The deadlock happens when any be2net hook (e.g. open/close) is called
in parallel to insmod ocrdma.ko.

A. be2net is sending administrative open/close event to ocrdma holding
   device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net.
   So sequence of locks is rtnl_lock---> device_list lock

B.  When new ocrdma roce device gets registered, infiniband stack now
    takes rtnl_lock in ib_register_device() in GID initialization routines.
    So sequence of locks in this path is device_list lock ---> rtnl_lock.

This improper locking sequence causes deadlock.

In order to resolve the above deadlock condition, ocrdma intorduced a
patch to stop listening to administrative open/close events generated from
be2net driver. It now depends on link-state-change async-event generated from
CNA. This change leaves behind dead code which used to generate administrative
open/close events. This patch cleans-up all that dead code from be2net.

The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured.  We need to make sure we have the
resources before we enable NTUPLE.  Add bnxt_rfs_capable() to do the
checking.

In addition, we need to do the same checking in ndo_fix_features().  As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.

Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem.  To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().

1dfddff5fc net: cdc_ncm: avoid changing RX/TX buffers on MTU changes
NCM buffer sizes are negotiated with the device independently of
the network device MTU.  The RX buffers are allocated by the
usbnet framework based on the rx_urb_size value set by cdc_ncm. A
single RX buffer can hold a number of MTU sized packets.

The default usbnet change_mtu ndo only modifies rx_urb_size if it
is equal to hard_mtu.  And the cdc_ncm driver will set rx_urb_size
and hard_mtu independently of each other, based on dwNtbInMaxSize
and dwNtbOutMaxSize respectively. It was therefore assumed that
usbnet_change_mtu() would never touch rx_urb_size.  This failed to
consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens
to be equal.

Fix by implementing an NCM specific change_mtu ndo, modifying the
netdev MTU without touching the buffer size settings.

f5e2ed022d dsa: mv88e6xxx: Add Second back of statistics
The 6320 family of switch chips has a second bank for statistics, but
is missing three statistics in the port registers. Generalise and
extend the code:

* adding a field to the statistics table indicating the bank/register
  set where each statistics is.
* add a function indicating if an individual statistics
  is available on this device
* calculate at run time the sset_count.
* return strings based on the available statistics of the device
* return statistics based on the available statistics of the device
* Add support for reading from the second bank.

09a04204f0 sfc: Downgrade or remove some error messages
Depending on configuration the NIC may return errors for unprivileged
functions and/or VFs. Where these are expected and handled, reduce the
level of any output.

8c578368e8 sfc: Downgrade EPERM messages from MCDI to debug
When running in an unprivileged function we expect some MC commands
to fail with permission errors. To avoid log spew downgrade these to
debug only.

e65a510918 sfc: Make failed filter removal less noisy
There are situations - mostly reset related - where our view of the
filter table differs from the hardware. In this case we may try and
remove filters that aren't actually installed. This isn't that
interesting in most situations, so downgrade the logging.

acd43a9097 sfc: Handle MCDI proxy authorisation
For unprivileged functions operations can be authorised by an admin
function. Extra steps are introduced to the MCDI protocol in this
situation - the initial response from the MCDI tells us that the
operation has been deferred, and we must retry when told. We then
receive an event telling us to retry.

Note that this provides only the functionality for the unprivileged
functions, not the handling of the administrative side.

ac28d179b8 sfc: Retry MCDI after NO_EVB_PORT error on a VF
After reboot the vswitch configuration from the PF may not be
complete before the VF attempts to restore filters. In that
case we see NO_EVB_PORT errors from the MC. Retry up to a time
limit or until a different result is seen.

0de60af649 net/mlx5_core: Introduce access functions to enable/disable RoCE
A mlx5 Ethernet port must be explicitly enabled for RoCE.
When RoCE is not enabled on the port, the NIC will refuse to create
QPs attached to it and incoming RoCE packets will be considered by the
NIC as plain Ethernet packets.

e5f6175c5b net/mlx5_core: Break down the vport mac address query function
Introduce a new function called mlx5_query_nic_vport_context().
This function gets all the NIC vport attributes from the device.

The MAC address is just one of the NIC vport attributes, so
mlx5_query_nic_vport_mac_address() is now just a wrapper function
above mlx5_query_nic_vport_context().

More NIC vport attributes will be used in following commits.
