====================
NFC 4.5 pull request

This is the first NFC pull request for 4.5 and it brings:

- A new driver for the STMicroelectronics ST95HF NFC chipset.
  The ST95HF is an NFC digital transceiver with an embedded analog
  front-end and as such relies on the Linux NFC digital
  implementation. This is the 3rd user of the NFC digital stack.

- ACPI support for the ST st-nci and st21nfca drivers.

- A small improvement for the nfcsim driver, as we can now tune
  the Rx delay through sysfs.

- A bunch of minor cleanups and small fixes from Christophe Ricard,
  for a few drivers and the NFC core code.

      sctp: sctp should release assoc when sctp_make_abort_user return NULL in sctp_close · 068d8bd3
      Xin Long authored 
      In sctp_close, sctp_make_abort_user may return NULL because of memory
allocation failure. If this happens, it will bypass any state change
and never free the assoc. The assoc has no chance to be freed and it
will be kept in memory with the state it had even after the socket is
closed by sctp_close().

So if sctp_make_abort_user fails to allocate memory, we should abort
the asoc via sctp_primitive_ABORT as well. Just like the annotation in
sctp_sf_cookie_wait_prm_abort and sctp_sf_do_9_1_prm_abort said,
"Even if we can't send the ABORT due to low memory delete the TCB.
This is a departure from our typical NOMEM handling".

But then the chunk is NULL (low memory) and the SCTP_CMD_REPLY cmd would
dereference the chunk pointer, and system crash. So we should add
SCTP_CMD_REPLY cmd only when the chunk is not NULL, just like other
places where it adds SCTP_CMD_REPLY cmd.

      net, socket, socket_wq: fix missing initialization of flags · 574aab1e
      Nicolai Stange authored 
      Commit ceb5d58b ("net: fix sock_wake_async() rcu protection") from
the current 4.4 release cycle introduced a new flags member in
struct socket_wq and moved SOCKWQ_ASYNC_NOSPACE and SOCKWQ_ASYNC_WAITDATA
from struct socket's flags member into that new place.

Unfortunately, the new flags field is never initialized properly, at least
not for the struct socket_wq instance created in sock_alloc_inode().

One particular issue I encountered because of this is that my GNU Emacs
failed to draw anything on my desktop -- i.e. what I got is a transparent
window, including the title bar. Bisection lead to the commit mentioned
above and further investigation by means of strace told me that Emacs
is indeed speaking to my Xorg through an O_ASYNC AF_UNIX socket. This is
reproducible 100% of times and the fact that properly initializing the
struct socket_wq ->flags fixes the issue leads me to the conclusion that
somehow SOCKWQ_ASYNC_WAITDATA got set in the uninitialized ->flags,
preventing my Emacs from receiving any SIGIO's due to data becoming
available and it got stuck.

Make sock_alloc_inode() set the newly created struct socket_wq's ->flags
member to zero.

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 5d6002b7 ("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).

====================
be2net: patch set

The following patch set contains some feature additions, code re-organization
and cleanup and a few non-critical fixes. Pls consider applying this to
the net-next tree. Thanks.

v3 changes: add a default case to the switch statement in patch 5 to
satisfy the compiler (-Wswitch).
v2 changes: replaced an if/else block that checks for error values with a
switch/case statement in patch 5.

Patch 1 fixes VF link state transition from disabled to auto that did
not work due to an issue in the FW. This issue could not be fixed in FW due
to some backward compatibility issues it causes with released drivers.
The issue has been fixed by introducing a new version (v2) of the cmd
from 10.6 FW onwards. This patch adds support for v2 version of this cmd.

Patch 2 reports a EOPNOTSUPP status to ethtool when the user tries to
configure BE3/SRIOV in VEPA mode as it is not supported by the chip.

Patch 3 cleansup FW flash image related constant definitions. Many of these
definitions (such as section offset values) were defined in decimal format
rather than hexa-decimal. This makes this part of the code un-readable.
Also some defines related to BE2 are labeld "g2" and defines related to BE3
are labeled "g3".  This patch cleans up all of this to make this code more
readable.

Patch 4 moves the FW cmd code to be_cmds.c. All code relating to FW cmds
has been in be_cmds.[ch], excepting FW flash cmd related code.
This patch moves these routines from be_main.c to be_cmds.c.

Patch 5 adds a log message to report digital signature errors while
flashing a FW image. From FW version 11.0 onwards, the FW supports a new
"secure mode" feature (based on a jumper setting on the adapter.) In this
mode, the FW image when flashed is authenticated with a digital signature.

Patch 6 removes a line of code that has no effect.

Patch 7 removes some unused variables.

Patch 8 fixes port resource descriptor query via the GET_PROFILE FW cmd.
An earlier commit passed a specific pf_num while issuing this 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.

Patch 9 adds support for ethtool get-dump feature. In the past when this
option was not yet available, this feature was supported via the
--register-dump option as a workaround.  This patch removes support for
FW-dump via --register-dump option as it is now available via --get-dump
option. Even though the "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 for diagnostics purpose.

Patch 10 bumps up the driver version.

      This patch removes a line of code that changes adapter->recommended_prio
value followed by yet another assignment.
Also, the variable is used to store the vlan priority value that is already
shifted to the PCP bits position in the vlan tag format. Hence, the name of
this variable is changed to recommended_prio_bits.
