mlx5 has the IANA VXLAN port (4789) hard coded by the device,
instead of being added dynamically when tunnels are created.
To support this add a workaround flag to struct udp_tunnel_nic_info.
Skipping updates for the port is fairly trivial, dumping the hard
coded port via ethtool requires some code duplication. The port
is not a part of any real table, we dump it in a special table
which has no tunnel types supported and only one entry.
This is the last known workaround / hack needed to convert
all drivers to the new infra.

The DR TX state machine supports the following order:
modify header, push vlan and encapsulation.
Instead fs_dr would pass:
push vlan, modify header and encapsulation.
The above caused the rule creation to fail on invalid action
sequence provided error.

Currently PF and VF representor netdevice carrier is always controlled
by controlling the representor netdevice device state as up/down.
Representor netdevice state change undergoes one or more txq/rxq
destroy/create commands to firmware, skb and its rx buffer allocation,
health reporters creation and more.
Due to this limitation users do not have the ability to just change
the carrier of the non uplink representors without modifying the
device state.
In one use case when the eswitch physical port carrier is down/up,
user needs to update the VF link state to same as physical port
carrier.
Example of updating VF representor carrier state:
$ ip link set enp0s8f0npf0vf0 carrier off
$ ip link set enp0s8f0npf0vf0 carrier on
This enhancement results into VF link state change which is
represented by the VF representor netdevice carrier.
This enables users to modify the representor carrier without modifying
the representor netdevice state.
A simple test is run using [1] to calculate the time difference between
updating carrier vs updating device state (to update just the carrier)
with one VF to simulate 255 VFs.
Time taken to update the carrier using device up/down:
$ time ./calculate.sh dev enp0s8f0npf0vf0
real 0m30.913s
user 0m0.200s
sys 0m11.168s
Time taken to update just the carrier using carrier iproute2 command:
$ time ./calculate.sh carrier enp0s8f0npf0vf0
real 0m2.142s
user 0m0.160s
sys 0m2.021s
Test shows that its better to use carrier on/off user interface to notify
link up/down event to VF compare to device up/down interface, because
carrier user interface delivers the same event 15 times faster.

Pull fscrypt updates from Eric Biggers:
"This release, we add support for inline encryption via the blk-crypto
framework which was added in 5.8.
Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt',
the contents of encrypted files will be encrypted/decrypted via
blk-crypto, instead of directly using the crypto API. This model
allows taking advantage of the inline encryption hardware that is
integrated into the UFS or eMMC host controllers on most mobile SoCs.
Note that this is just an alternate implementation; the ciphertext
written to disk stays the same.
(This pull request does *not* include support for direct I/O on
encrypted files, which blk-crypto makes possible, since that part is
still being discussed.)
Besides the above feature update, there are also a few fixes and
cleanups, e.g. strengthening some memory barriers that may be too
weak.
All these patches have been in linux-next with no reported issues.
I've also tested them with the fscrypt xfstests, as usual. It's also
been tested that the inline encryption support works with the support
for Qualcomm and Mediatek inline encryption hardware that will be in
the scsi pull request for 5.9. Also, several SoC vendors are already
using a previous, functionally equivalent version of these patches"

Pull btrfs updates from David Sterba:
"We don't have any big feature updates this time, there are lots of
small enhacements or fixes. A highlight perhaps is the parallel fsync
performance improvements, numbers below.
Regarding the dio/iomap that was reverted last time, the required API
changes are likely to land in the upcoming cycle, the btrfs part will
be updated afterwards.
User visible changes:
- new mount option rescue= to group all recovery-related mount
options so we don't have many specific options, currently
introducing only aliases for existing options, future extensions
are in development to allow read-only mount with partially damaged
structures:
- usebackuproot is an alias for rescue=usebackuproot
- nologreplay is an alias for rescue=nologreplay
- start deprecation of mount option inode_cache, removal scheduled to
v5.11
- removed deprecated mount options alloc_start and subvolrootid
- device stats corruption counter gets incremented when a checksum
mismatch is found
- qgroup information exported in /sys/fs/btrfs/<UUID>/qgroups/<id>
using sysfs
- add link /sys/fs/btrfs/<UUID>/bdi pointing to the associated
backing dev info
- FS_INFO ioctl enhancements:
- add flags to request/describe newly added items
- new item: numeric checksum type and checksum size
- new item: generation
- new item: metadata_uuid
- seed device: with one new read-write device added, print the new
device information in /proc/mounts
- balance: detect cancellation by Ctrl-C in existing cancellation
points
Performance improvements:
- optimized versions of various helpers on little-endian
architectures, where we don't have to do LE/BE conversion from
on-disk format
- tree-log/fsync optimizations leading to lower max latency reported
by dbench, reduced by about 12%
- all chunk tree leaves are prefetched at mount time, can improve
mount time on large (terabyte-sized) filesystems
- speed up parallel fsync of files with reflinked/deduped extents,
with jobs 16 to 1024 the throughput gets improved roughly by 50% on
average and runtime decreased roughly by 30% on average, notable
outlier is 128 jobs with +121.2% on throughput and -54.6% runtime
- another speed up of parallel fsync, reduce number of checksum tree
lookups and contention, the improvements start to show up with 2
tasks with +20% throughput and -16% runtime up to 64 with +200%
throughput and -66% runtime
Core:
- umount-time qgroup leak checker
- qgroups
- add a way to unreserve partial range after failure, avoiding
some EDQUOT errors
- improved flushing logic when EDQUOT is hit
- possible EINTR interruption caused by failed reservations after
transaction start is better handled and documented
- transaction abort errors are unified to EROFS in case it's not the
original reason of abort or we don't have other way to determine
the reason
Fixes:
- make truncate succeed on a NOCOW file even if data space is
exhausted
- fix cancelling balance on filesystem with exhausted metadata space
- anon block device:
- preallocate anon bdev when subvolume is created to report
failure early
- shorten time the anon bdev id is allocated
- don't allocate anon bdev for internal roots
- minor memory leak in ref-verify
- refuse invalid combinations of compression and NOCOW file flags
- lockdep fixes, updating the device locks
- remove obsolete fallback logic for block group profile adjustments
when switching from 1 to more devices, causing allocation of
unwanted block groups
Other cleanups, refactoring, simplifications:
- conversions from struct inode to struct btrfs_inode in internal
functions
- removal of unused struct members"

When the device is already gone we end up with the following scenario:
The device's capacity is 0 and thus the number of zones will be 0 as well. When
allocating the bitmap for the conventional zones, we then trip over a NULL
pointer.
So if we encounter a zoned block device with a 0 capacity, don't dare to
revalidate the zones sizes.

Andrii Nakryiko says:
====================
It's pretty common for applications to want to parse raw (binary) BTF data
from file, as opposed to parsing it from ELF sections. It's also pretty common
for tools to not care whether given file is ELF or raw BTF format. This patch
series exposes internal raw BTF parsing API and adds generic variant of BTF
parsing, which will efficiently determine the format of a given fail and will
parse BTF appropriately.
Patches #2 and #3 removes re-implementations of such APIs from bpftool and
resolve_btfids tools.

The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with
non-zero effect: the command failure is masked (despite `set -e`) and all but
the first command of $(dep-cmd) is executed (successfully, as they are mostly
printfs), thus overall returning 0 in the end.
This means in practice that despite compilation errors, tools's build Makefile
will return success. We see this very reliably with libbpf's Makefile, which
doesn't get compilation error propagated properly. This in turns causes issues
with selftests build, as well as bpftool and other projects that rely on
building libbpf.
The fix is simple: don't use &&. Given `set -e`, we don't need to chain
commands with &&. The shell will exit on first failure, giving desired
behavior and propagating error properly.

Multicolor is a bit too abstract. Yes, we can have
Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
RGB, and not even RGB-White or RGB-Yellow variants emerged.
Multicolor is not a good fit for RGB LED. It does not really know
about LED color. In particular, there's no way to make LED "white".
Userspace is interested in knowing "this LED can produce arbitrary
color", which not all multicolor LEDs can.

IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to
enable beacon filter support whenever power save is enabled, that is
IEEE80211_CONF_PS is set. When power save is enabled, the stack will
not check for beacon loss and the driver needs to notify about loss
of beacons with ieee80211_beacon_loss().
Some controllers may want to dynamically enable the beacon filter
capabilities on power save entry (CONF_PS) and disable it on exit.
This is the case for the wcn36xx driver which only supports beacon
filtering in PS mode (no CONNECTION_MONITOR support).
When the mac80211 beacon monitor timer expires, the beacon filter
flag must be checked again in case it as been changed in between
(e.g. vif moved to PS mode).

On heavily loaded systems the GC can take time to go over all existing
conns and reset their timeout. At that time other calls like from
nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as
expired. To fix this when we set the offload bit we should also reset
the timeout instead of counting on GC to finish first iteration over
all conns before the initial timeout.

SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK
(WFA) options. Those extensions use special status code values in the
SAE commit messages (Authentication frame with transaction sequence
number 1) to identify which extension is in use. mac80211 was
interpreting those new values as the AP denying authentication and that
resulted in failure to complete SAE authentication in some cases.
Fix this by adding exceptions for the new status code values 126 and
127.

Degraded raid6 always do reconstruct-write now. With raid6 xor supported,
we can do rmw in degraded raid6. This patch can reduce many read IOs to
improve performance.
If the failed disk is P, Q or the disk we want to write to, we may need to
do reconstruct-write in max degraded raid6. In this situation we can not
read enough data from handle_stripe_dirtying() so we have to set force_rcw
in handle_stripe_fill() to read all data.

In degraded raid5, we need to read parity to do reconstruct-write when
data disks fail. However, we can not read parity from
handle_stripe_dirtying() in force reconstruct-write mode.
Reproducible Steps:
1. Create degraded raid5
mdadm -C /dev/md2 --assume-clean -l5 -n3 /dev/sda2 /dev/sdb2 missing
2. Set rmw_level to 0
echo 0 > /sys/block/md2/md/rmw_level
3. IO to raid5
Now some io may be stuck in raid5. We can use handle_stripe_fill() to read
the parity in this situation.

To grow size of super 1.0 raid array, it is necessary to check the device
max usable size.
Now it uses rdev->sectors for max usable size. If one disk is 500G and the
raid device only uses the 100GB of this disk. rdev->sectors can't tell the
real max usable size. The max usable size should be
dev_size-(superblock_size+bitmap_size+badblock_size).
Also, remove unnecessary sb_start update in super_1_rdev_size_change().

It turns out that wait_on_page_bit_common() had several problems,
ranging from just unfair behavioe due to re-queueing at the end of the
wait queue when re-trying, and an outright bug that could result in
missed wakeups (but probably never happened in practice).
This rewrites the whole logic to avoid both issues, by simply moving the
logic to check (and possibly take) the bit lock into the wakeup path
instead.
That makes everything much more straightforward, and means that we never
need to re-queue the wait entry: if we get woken up, we'll be notified
through WQ_FLAG_WOKEN, and the wait queue entry will have been removed,
and everything will have been done for us.
