      net/mlx5: E-Switch, Fix resetting of encap mode when entering switchdev · d7751d64
      Paul Blakey authored 
      E-Switch encap mode is relevant only when in switchdev mode.
The RDMA driver can query the encap configuration via
mlx5_eswitch_get_encap_mode(). Make sure it returns the currently
used mode and not the set one.

This reverts the cited commit which reset the encap mode
on entering switchdev and fixes the original issue properly.

      net/mlx5e: Wait for concurrent flow deletion during neigh/fib events · 362980ea
      Vlad Buslov authored 
      Function mlx5e_take_tmp_flow() skips flows with zero reference count. This
can cause syndrome 0x179e84 when the called from neigh or route update code
and the skipped flow is not removed from the hardware by the time
underlying encap/decap resource is deleted. Add new completion
'del_hw_done' that is completed when flow is unoffloaded. This is safe to
do because flow with reference count zero needs to be detached from
encap/decap entry before its memory is deallocated, which requires taking
the encap_tbl_lock mutex that is held by the event handlers code.

      net/mlx5e: kTLS, Fix crash in RX resync flow · cc4a9cc0
      Tariq Toukan authored 
      For the TLS RX resync flow, we maintain a list of TLS contexts
that require some attention, to communicate their resync information
to the HW.
Here we fix list corruptions, by protecting the entries against
movements coming from resync_handle_seq_match(), until their resync
handling in napi is fully completed.

====================
Intel Wired LAN Driver Updates 2021-11-15

This series contains updates to iavf driver only.

Mateusz adds a wait for reset completion when changing queue count which
could otherwise cause issues with VF reset.

Nick adds a null check for vf_res in iavf_fix_features(), corrects
ordering of function calls to resolve dependency issues, and prevents
possible freeing of a lock which isn't being held.

Piotr fixes logic that did not allow setting all multicast mode without
promiscuous mode.

Jake prevents possible accidental freeing of filter structure.

Mitch adds null checks for key and indir parameters in iavf_get_rxfh().

Surabhi adds an additional check that would, previously, cause the driver
to print a false error due to values obtained while the VF is in reset.

Grzegorz prevents a queue request of 0 which would cause queue count to
reset to default values.

Akeem restores VLAN filters when bringing the interface back up.

      net,lsm,selinux: revert the security_sctp_assoc_established() hook · 1aa3b220
      Paul Moore authored 
      This patch reverts two prior patches, e7310c94
("security: implement sctp_assoc_established hook in selinux") and
7c2ef024 ("security: add sctp_assoc_established hook"), which
create the security_sctp_assoc_established() LSM hook and provide a
SELinux implementation.  Unfortunately these two patches were merged
without proper review (the Reviewed-by and Tested-by tags from
Richard Haines were for previous revisions of these patches that
were significantly different) and there are outstanding objections
from the SELinux maintainers regarding these patches.

Work is currently ongoing to correct the problems identified in the
reverted patches, as well as others that have come up during review,
but it is unclear at this point in time when that work will be ready
for inclusion in the mainline kernel.  In the interest of not keeping
objectionable code in the kernel for multiple weeks, and potentially
a kernel release, we are reverting the two problematic patches.
