10eb3a0d51 dm: fix race in dm_start_io_acct
After commit 82f6cdcc36 ("dm: switch dm_io booleans over to proper
flags") dm_start_io_acct stopped atomically checking and setting
was_accounted, which turned into the DM_IO_ACCOUNTED flag. This opened
the possibility for a race where IO accounting is started twice for
duplicate bios. To remove the race, check the flag while holding the
io->lock.

a625357997 arm64: ftrace: consistently handle PLTs.
Sometimes it is necessary to use a PLT entry to call an ftrace
trampoline. This is handled by ftrace_make_call() and ftrace_make_nop(),
with each having *almost* identical logic, but this is not handled by
ftrace_modify_call() since its introduction in commit:

  3b23e4991f ("arm64: implement ftrace with regs")

Due to this, if we ever were to call ftrace_modify_call() for a callsite
which requires a PLT entry for a trampoline, then either:

a) If the old addr requires a trampoline, ftrace_modify_call() will use
   an out-of-range address to generate the 'old' branch instruction.
   This will result in warnings from aarch64_insn_gen_branch_imm() and
   ftrace_modify_code(), and no instructions will be modified. As
   ftrace_modify_call() will return an error, this will result in
   subsequent internal ftrace errors.

b) If the old addr does not require a trampoline, but the new addr does,
   ftrace_modify_call() will use an out-of-range address to generate the
   'new' branch instruction. This will result in warnings from
   aarch64_insn_gen_branch_imm(), and ftrace_modify_code() will replace
   the 'old' branch with a BRK. This will result in a kernel panic when
   this BRK is later executed.

Practically speaking, case (a) is vastly more likely than case (b), and
typically this will result in internal ftrace errors that don't
necessarily affect the rest of the system. This can be demonstrated with
an out-of-tree test module which triggers ftrace_modify_call(), e.g.

We can solve this by consistently determining whether to use a PLT entry
for an address.

Note that since (the earlier) commit:

  f1a54ae9af ("arm64: module/ftrace: intialize PLT at load time")

... we can consistently determine the PLT address that a given callsite
will use, and therefore ftrace_make_nop() does not need to skip
validation when a PLT is in use.

This patch factors the existing logic out of ftrace_make_call() and
ftrace_make_nop() into a common ftrace_find_callable_addr() helper
function, which is used by ftrace_make_call(), ftrace_make_nop(), and
ftrace_modify_call(). In ftrace_make_nop() the patching is consistently
validated by ftrace_modify_code() as we can always determine what the
old instruction should have been.

3eefdf9d1e arm64: ftrace: fix branch range checks
The branch range checks in ftrace_make_call() and ftrace_make_nop() are
incorrect, erroneously permitting a forwards branch of 128M and
erroneously rejecting a backwards branch of 128M.

This is because both functions calculate the offset backwards,
calculating the offset *from* the target *to* the branch, rather than
the other way around as the later comparisons expect.

If an out-of-range branch were erroeously permitted, this would later be
rejected by aarch64_insn_gen_branch_imm() as branch_imm_common() checks
the bounds correctly, resulting in warnings and the placement of a BRK
instruction. Note that this can only happen for a forwards branch of
exactly 128M, and so the caller would need to be exactly 128M bytes
below the relevant ftrace trampoline.

If an in-range branch were erroeously rejected, then:

* For modules when CONFIG_ARM64_MODULE_PLTS=y, this would result in the
  use of a PLT entry, which is benign.

  Note that this is the common case, as this is selected by
  CONFIG_RANDOMIZE_BASE (and therefore RANDOMIZE_MODULE_REGION_FULL),
  which distributions typically seelct. This is also selected by
  CONFIG_ARM64_ERRATUM_843419.

* For modules when CONFIG_ARM64_MODULE_PLTS=n, this would result in
  internal ftrace failures.

* For core kernel text, this would result in internal ftrace failues.

  Note that for this to happen, the kernel text would need to be at
  least 128M bytes in size, and typical configurations are smaller tha
  this.

Fix this by calculating the offset *from* the branch *to* the target in
both functions.

Fixes: e71a4e1beb ("arm64: ftrace: add support for far branches to dynamic ftrace")

This reverts commit 73e2d827a5.

The reverted patch was needed as a fix after commit f5bda35fba
("random: use static branch for crng_ready()"). However, this was
already fixed by 60e5b2886b ("random: do not use jump labels before
they are initialized") and hence no longer necessary to initialise jump
labels before setup_machine_fdt().

3046a82731 bpf: Fix request_sock leak in sk lookup helpers
A customer reported a request_socket leak in a Calico cloud environment. We
found that a BPF program was doing a socket lookup with takes a refcnt on
the socket and that it was finding the request_socket but returning the parent
LISTEN socket via sk_to_full_sk() without decrementing the child request socket
1st, resulting in request_sock slab object leak. This patch retains the
existing behaviour of returning full socks to the caller but it also decrements
the child request_socket if one is present before doing so to prevent the leak.

Thanks to Curtis Taylor for all the help in diagnosing and testing this. And
thanks to Antoine Tenart for the reproducer and patch input.

v2 of this patch contains, refactor as per Daniel Borkmann's suggestions to
validate RCU flags on the listen socket so that it balances with bpf_sk_release()
and update comments as per Martin KaFai Lau's suggestion. One small change to
Daniels suggestion, put "sk = sk2" under "if (sk2 != sk)" to avoid an extra
instruction.

219b51a6f0 net: ax25: Fix deadlock caused by skb_recv_datagram in ax25_recvmsg
The skb_recv_datagram() in ax25_recvmsg() will hold lock_sock
and block until it receives a packet from the remote. If the client
doesn`t connect to server and calls read() directly, it will not
receive any packets forever. As a result, the deadlock will happen.

The fail log caused by deadlock is shown below:

This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.

what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

regmap: provide regmap_field helpers for simple bit operations
We have set/clear/test operations for regmap, but not for regmap_field yet.
So let's introduce regmap_field helpers too.

In many instances regmap_field_update_bits() is used for simple bit setting
and clearing. In these cases the last argument is redundant and we can
hide it with a static inline function.

This adds three new helpers for simple bit operations: set_bits,
clear_bits and test_bits (the last one defined as a regular function).

36a15e1cb1 net: usb: ax88179_178a needs FLAG_SEND_ZLP
The extra byte inserted by usbnet.c when
 (length % dev->maxpacket == 0) is causing problems to device.

This patch sets FLAG_SEND_ZLP to avoid this.

Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet

Problems observed:
======================================================================
1) Using ssh/sshfs. The remote sshd daemon can abort with the message:
   "message authentication code incorrect"
   This happens because the tcp message sent is corrupted during the
   USB "Bulk out". The device calculate the tcp checksum and send a
   valid tcp message to the remote sshd. Then the encryption detects
   the error and aborts.
2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out
3) Stop normal work without any log message.
   The "Bulk in" continue receiving packets normally.
   The host sends "Bulk out" and the device responds with -ECONNRESET.
   (The netusb.c code tx_complete ignore -ECONNRESET)
Under normal conditions these errors take days to happen and in
intense usage take hours.

A test with ping gives packet loss, showing that something is wrong:
ping -4 -s 462 {destination}	# 462 = 512 - 42 - 8
Not all packets fail.
My guess is that the device tries to find another packet starting
at the extra byte and will fail or not depending on the next
bytes (old buffer content).

56ec3e755b ALSA: hda/realtek: Apply fixup for Lenovo Yoga Duet 7 properly
It turned out that Lenovo shipped two completely different products
with the very same PCI SSID, where both require different quirks;
namely, Lenovo C940 has already the fixup for its speaker
(ALC298_FIXUP_LENOVO_SPK_VOLUME) with the PCI SSID 17aa:3818, while
Yoga Duet 7 has also the very same PCI SSID but requires a different
quirk, ALC287_FIXUP_YOGA7_14TIL_SPEAKERS.

Fortunately, both are with different codecs (C940 with ALC298 and Duet
7 with ALC287), hence we can apply different fixes by checking the
codec ID.  This patch implements that special fixup function.

For easier handling, the internal function for applying a specific
fixup entry is exported as __snd_hda_apply_fixup(), so that it can be
called from the codec driver.  The rest is simply calling it with a
different fixup ID depending on the codec ID.

2a3dcbccd6 9p: Fix refcounting during full path walks for fid lookups
Decrement the refcount of the parent dentry's fid after walking
each path component during a full path walk for a lookup. Failure to do
so can lead to fids that are not clunked until the filesystem is
unmounted, as indicated by this warning:

 9pnet: found fid 3 not clunked

The improper refcounting after walking resulted in open(2) returning
-EIO on any directories underneath the mount point when using the virtio
transport. When using the fd transport, there's no apparent issue until
the filesytem is unmounted and the warning above is emitted to the logs.

In some cases, the user may not yet be attached to the filesystem and a
new root fid, associated with the user, is created and attached to the
root dentry before the full path walk is performed. Increment the new
root fid's refcount to two in that situation so that it can be safely
decremented to one after it is used for the walk operation. The new fid
will still be attached to the root dentry when
v9fs_fid_lookup_with_uid() returns so a final refcount of one is
correct/expected.

795285ef24 selftests: Fix clang cross compilation
Unlike GCC clang uses a single compiler image to support multiple target
architectures meaning that we can't simply rely on CROSS_COMPILE to select
the output architecture. Instead we must pass --target to the compiler to
tell it what to output, kselftest was not doing this so cross compilation
of kselftest using clang resulted in kselftest being built for the host
architecture.

More work is required to fix tests using custom rules but this gets the
bulk of things building.

4fd17f2ac0 drm/amd/display: Cap OLED brightness per max frame-average luminance
[Why]
For OLED eDP the Display Manager uses max_cll value as a limit
for brightness control.
max_cll defines the content light luminance for individual pixel.
Whereas max_fall defines frame-average level luminance.
The user may not observe the difference in brightness in between
max_fall and max_cll.
That negatively impacts the user experience.

[How]
Use max_fall value instead of max_cll as a limit for brightness control.

d884b6498d io_uring: remove IORING_CLOSE_FD_AND_FILE_SLOT
This partially reverts a7c41b4687

Even though IORING_CLOSE_FD_AND_FILE_SLOT might save cycles for some
users, but it tries to do two things at a time and it's not clear how to
handle errors and what to return in a single result field when one part
fails and another completes well. Kill it for now.

efe4186000 ice: Fix memory corruption in VF driver
Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,
while VF still has queues configured, VF may unmap DMA resources.
In such scenario device still can map packets to memory, which ends up
silently corrupting it.
Previously, VF driver could experience memory corruption, which lead to
crash:

be2af71496 ice: Fix queue config fail handling
Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail.
Not disabling them might lead to scenario, where PF driver leaves VF
queues enabled, when VF's VSI failed queue config.
In this scenario VF should not have RX/TX queues enabled. If PF failed
to set up VF's queues, VF will reset due to TX timeouts in VF driver.
Initialize iterator 'i' to -1, so if error happens prior to configuring
queues then error path code will not disable queue 0. Loop that
configures queues will is using same iterator, so error path code will
only disable queues that were configured.
