An encrypted file name should never be shorter than an 16 bytes, the

if ciphertext shorter than the block size is passed to it.
Fortunately, in modern kernels the crypto layer will not crash the

Lots of devices support huge discard sizes these days. Depending
on how the device handles them internally, huge discards can
introduce massive latencies (hundreds of msec) on the device side.
We have a sysfs file, discard_max_bytes, that advertises the max
hardware supported discard size. Make this writeable, and split
the settings into a soft and hard limit. This can be set from
'discard_granularity' and up to the hardware limit.
Add a new sysfs file, 'discard_max_hw_bytes', that shows the hw

Storing internal frames in macroblock tiled order improves memory
access patterns by allowing increased burst sizes when transferring
the uncompressed macroblocks to or from main memory.
The translation logic only supports a single chroma base address,
so this is only supported for the chroma interleaved NV12 format.
Since the rotator used to copy the decoder output into the v4l2
capture buffers does not seem to support the tiled format correctly,
only enable it in the encoder for now.

Linus noticed that the early return check was missing

_TIF_USER_RETURN_NOTIFY, we'd skip user return notifiers. Fix
it. (This is the only missing bit.)
This fixes double faults on a KVM host. It's the same issue as
last time, except that this time it's very easy to trigger.
Apparently no one uses -next as a KVM host.
( I'm still not quite sure what it is that KVM does that blows up
so badly if we miss a user return notifier. My best guess is that KVM
lets KERNEL_GS_BASE (i.e. the user's gs base) be negative and fixes
it up in a user return notifier. If we actually end up in user mode
with a negative gs base, we blow up pretty badly. )

Instead of using peer link id for AID, generate a new
AID when creating mesh STAs in the kernel peering manager.
This enables smaller TIM elements and more closely follows
the standard, and it also enables mesh to work on drivers
that require a valid AID when the STA is inserted (ath10k
firmware has this requirement, for example).
In the case of userspace-managed stations, we use the AID
from NL80211_CMD_NEW_STATION.

According to 802.11-2012 13.3.1, a mesh STA should assign an AID
upon receipt of a mesh peering open frame rather than using the link
id of the peer. Using the peer link id has two potential issues:
it may not be unique among the peers, and by its nature it is random,
so the TIM may not compress well.
In preparation for allocating it properly, use sta->sta.aid, but keep
the existing behavior of using the plid in the aid we send.

Currently, mac80211 calls drv_resume() on wowlan resume,
but drops any incoming frame until local->suspended is
cleared later on.
This requires the low-level driver to support a new state,
in which it is expected to fully work (as it was resumed)
but not passing rx frames yet (as they will be dropped).
iwlwifi (and probably other drivers as well) has issues
supporting such mode.
Since in the wowlan case we already short-circuit
ieee80211_reconfig, there's nothing that prevents us from
clearing local->suspend before calling drv_resume(),
and letting the low-level driver work normally.

Move TDLS channel-switch Rx handling into an RTNL locked work. This is
required to add proper regulatory checking to incoming channel-switch
requests.
Queue incoming requests in a dedicated skb queue and handle the request
in a device-specific work to avoid deadlocking on interface removal.

Add support for declaring MU-MIMO beamformee capability for
relevant hardware.
When sending association request, the capability is included if both
hardware and the AP support it, and no other virtual interface
is using it.
This is in order to avoid multiple interfaces using MU-MIMO in parallel
which might lead to contradictions in the group-id mechanism.

If an SKB will be segmented by the driver, count it for multiple
MSDUs that are being transmitted rather than just a single.

Commit eeca9fce1d ('cfg80211: Schedule timeout for all CRDA calls')
left behind a superfluous check after it removed some earlier code.
In reg_process_hint, the test of "treatment == REG_REQ_IGNORE ||
treatment == REG_REQ_ALREADY_SET" is superfluous because the code in the
if-then branch is identical to the code after the if statement.
Coverity CID #1295939
I also removed the unnecessary assignment of treatment in this case,
and added a comment reminding any future patch authors to ensure that
treatment is properly assigned before it is used after the switch.
