 "This contains a few small fixes. This comes with some delay because I
  wanted to wait on people running their reproducers and the Easter
  Holidays meant that those replies came in a little later than usual:

   - Fix handling of preventing writes to mounted block devices.

     Since last kernel we allow to prevent writing to mounted block
     devices provided CONFIG_BLK_DEV_WRITE_MOUNTED isn't set and the
     block device is opened with restricted writes. When we switched to
     opening block devices as files we altered the mechanism by which we
     recognize when a block device has been opened with write
     restrictions.

     The detection logic assumed that only read-write mounted
     filesystems would apply write restrictions to their block devices
     from other openers. That of course is not true since it also makes
     sense to apply write restrictions for filesystems that are
     read-only.

     Fix the detection logic using an FMODE_* bit. We still have a few
     left since we freed up a couple a while ago. I also picked up a
     patch to free up four additional FMODE_* bits scheduled for the
     next merge window.

   - Fix counting the number of writers to a block device. This just
     changes the logic to be consistent.

   - Fix a bug in aio causing a NULL pointer derefernce after we
     implemented batched processing in aio.

   - Finally, add the changes we discussed that allows to yield block
     devices early even though file closing itself is deferred.

     This also allows us to remove two holder operations to get and
     release the holder to align lifetime of file and holder of the
     block device"

  block: count BLK_OPEN_RESTRICT_WRITES openers
  block: handle BLK_OPEN_RESTRICT_WRITES correctly

list_del_init_careful() needs to be the last access to the wait queue
entry - it effectively unlocks access.

Previously, finish_wait() would see the empty list head and skip taking
the lock, and then we'd return - but the completion path would still
attempt to do the wakeup after the task_struct pointer had been
overwritten.

Add CPUID_LNX_5 to track cpufeatures' word 21, and add the appropriate
compile-time assert in KVM to prevent direct lookups on the features in
CPUID_LNX_5.  KVM uses X86_FEATURE_* flags to manage guest CPUID, and so
must translate features that are scattered by Linux from the Linux-defined
bit to the hardware-defined bit, i.e. should never try to directly access
scattered features in guest CPUID.

Opportunistically add NR_CPUID_WORDS to enum cpuid_leafs, along with a
compile-time assert in KVM's CPUID infrastructure to ensure that future
additions update cpuid_leafs along with NCAPINTS.

No functional change intended.

Pull bcachefs repair code from Kent Overstreet:
 "A couple more small fixes, and new repair code.

  We can now automatically recover from arbitrary corrupted interior
  btree nodes by scanning, and we can reconstruct metadata as needed to
  bring a filesystem back into a working, consistent, read-write state
  and preserve access to whatevver wasn't corrupted.

  Meaning - you can blow away all metadata except for extents and
  dirents leaf nodes, and repair will reconstruct everything else and
  give you your data, and under the correct paths. If inodes are missing
  i_size will be slightly off and permissions/ownership/timestamps will
  be gone, and we do still need the snapshots btree if snapshots were in
  use - in the future we'll be able to guess the snapshot tree structure
  in some situations.

  IOW - aside from shaking out remaining bugs (fuzz testing is still
  coming), repair code should be complete and if repair ever doesn't
  work that's the highest priority bug that I want to know about
  immediately.

  This patchset was kindly tested by a user from India who accidentally
  wiped one drive out of a three drive filesystem with no replication on
  the family computer - it took a couple weeks but we got everything
  important back"

a total of 9 files changed, 75 insertions(+), 24 deletions(-).

The main changes are:

1) Fix x86 BPF JIT under retbleed=stuff which causes kernel panics due to
   incorrect destination IP calculation and incorrect IP for relocations,
   from Uros Bizjak and Joan Bruguera Micó.

2) Fix BPF arena file descriptor leaks in the verifier,
   from Anton Protopopov.

3) Defer bpf_link deallocation to after RCU grace period as currently
   running multi-{kprobes,uprobes} programs might still access cookie
   information from the link, from Andrii Nakryiko.

4) Fix a BPF sockmap lock inversion deadlock in map_delete_elem reported
   by syzkaller, from Jakub Sitnicki.

5) Fix resolve_btfids build with musl libc due to missing linux/types.h
   include, from Natanael Copa.

Commit 1b600da5 ("PM: EM: Optimize em_cpu_energy() and remove division")
has added back map_util_perf() in em_cpu_energy() computation which has
been removed with the rework of scheduler/cpufreq interface.
This is wrong because sugov_effective_cpu_perf() already takes care of
mapping the utilization to a performance level.

When adding sanitization of the label, the path through
edge_detector_setup() that leads to debounce_setup() was overlooked.
A request taking this path does not allocate a new label and the
request label is freed twice when the request is released, resulting
in memory corruption.

Add label sanitization to debounce_setup().

I got multiple syzbot reports showing old bugs exposed
by BPF after commit 20f2505f ("bpf: Try to avoid kzalloc
in cgroup/{s,g}etsockopt")

setsockopt() @optlen argument should be taken into account
before copying data.

Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

Patch #1 unlike early commit path stage which triggers a call to abort,
         an explicit release of the batch is required on abort, otherwise
         mutex is released and commit_list remains in place.

Patch #2 release mutex after nft_gc_seq_end() in commit path, otherwise
         async GC worker could collect expired objects.

Patch #3 flush pending destroy work in module removal path, otherwise UaF
         is possible.

Patch #4 and #6 restrict the table dormant flag with basechain updates
	 to fix state inconsistency in the hook registration.

Patch #5 adds missing RCU read side lock to flowtable type to avoid races
	 with module removal.

syzbot found that tcf_skbmod_dump() was copying four bytes
from kernel stack to user space [1].

The issue here is that 'struct tc_skbmod' has a four bytes hole.

We need to clear the structure before filling fields.

After the commit d2689b6a ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset is not executed from bind operation and
mac address is not read from the device registers or the devicetree at that
moment. Since the check to configure if the assigned mac address is random
or not for the interface, happens after the bind operation from
usbnet_probe, the interface keeps configured as random address, although the
address is correctly read and set during open operation (the only reset
now).

In order to keep only one reset for the device and to avoid the interface
always configured as random address, after reset, configure correctly the
suitable field from the driver, if the mac address is read successfully from
the device registers or the devicetree. Take into account if a locally
administered address (random) was previously stored.

We need to take into account that a line's consumer label may be NULL
and not try to kstrdup() it in that case but rather pass the NULL
pointer up the stack to the interrupt request function.

To that end: let make_irq_label() return NULL as a valid return value
and use ERR_PTR() instead to signal an allocation failure to callers.

Preempt fences can sleep waiting for an exec queue suspend operation to
complete. If the system_unbound_wq is used for waiting and the number of
waiters exceeds max_active this will result in other users of the
system_unbound_wq getting starved. Use a device private work queue for
preempt fences to avoid starvation of the system_unbound_wq.

Even though suspend operations can complete out-of-order, all suspend
operations within a VM need to complete before the preempt rebind worker
can start. With that, use a device private ordered wq for preempt fence
waiting.

 - Add comment about cleanup on failure (Matt R)
 - Update commit message (Lucas)

Rebinding might allocate page-table bos, causing evictions.
To support blocking locking during these evictions,
perform the rebinding in the drm_exec locking loop.

Also Reserve fence slots where actually needed rather than trying to

wound-wait transaction.

For each rebind we insert a GuC TLB invalidation and add a
corresponding unordered TLB invalidation fence. This might
add a huge number of TLB invalidation fences to wait for so
rather than doing that, defer the TLB invalidation to the
next ring ops for each affected exec queue. Since the TLB
is invalidated on exec_queue switch, we need to invalidate
once for each affected exec_queue.

v2:
- Simplify if-statements around the tlb_flush_seqno.
  (Matthew Brost)
- Add some comments and asserts.

Before ACP firmware loading, DSP interrupts are not expected.
Sometimes after reboot, it's observed that before ACP firmware is loaded
false DSP interrupt is reported.
Registering the interrupt handler before acp initialization causing false
interrupts sometimes on reboot as ACP reset is not applied.
Correct the sequence by invoking acp initialization sequence prior to
registering interrupt handler.

The definition and declaration of sja1110_pcs_mdio_write_c45() don't have
parameters in the same order.

Knowing that sja1110_pcs_mdio_write_c45() is used as a function pointer
in 'sja1105_info' structure with .pcs_mdio_write_c45, and that we have:

   int (*pcs_mdio_write_c45)(struct mii_bus *bus, int phy, int mmd,
				  int reg, u16 val);

it is likely that the definition is the one to change.

Found with cppcheck, funcArgOrderDifferent.

The error statistics should be updated each time the poll function is
called, even if the full RX work budget has been consumed. This prevents
the counts from becoming stuck when RX bandwidth usage is high.

This also ensures that error counters are not updated after we've
re-enabled interrupts as that could result in a race condition.

Also drop an unnecessary space.
