  ufs_rename(): fix bogus argument of folio_release_kmap()

Brandon reports sporadic, non-sensical spikes in cumulative pressure
time (total=) when reading cpu.pressure at a high rate. This is due to
a race condition between reader aggregation and tasks changing states.

While it affects all states and all resources captured by PSI, in
practice it most likely triggers with CPU pressure, since scheduling
events are so frequent compared to other resource events.

The race context is the live snooping of ongoing stalls during a
pressure read. The read aggregates per-cpu records for stalls that
have concluded, but will also incorporate ad-hoc the duration of any
active state that hasn't been recorded yet. This is important to get
timely measurements of ongoing stalls. Those ad-hoc samples are
calculated on-the-fly up to the current time on that CPU; since the
stall hasn't concluded, it's expected that this is the minimum amount
of stall time that will enter the per-cpu records once it does.

The problem is that the path that concludes the state uses a CPU clock
read that is not synchronized against aggregators; the clock is read
outside of the seqlock protection. This allows aggregators to race and
snoop a stall with a longer duration than will actually be recorded.

With the recorded stall time being less than the last snapshot
remembered by the aggregator, a subsequent sample will underflow and
observe a bogus delta value, resulting in an erratic jump in pressure.

Fix this by moving the clock read of the state change into the seqlock
protection. This ensures no aggregation can snoop live stalls past the
time that's recorded when the state concludes.

In `gpiod_get_label()`, it is possible that `srcu_dereference_check()` may
return a NULL pointer, leading to a scenario where `label->str` is accessed
without verifying if `label` itself is NULL.

This patch adds a proper NULL check for `label` before accessing
`label->str`. The check for `label->str != NULL` is removed because
`label->str` can never be NULL if `label` is not NULL.

This fixes the issue where the label name was being printed as `(efault)`
when dumping the sysfs GPIO file when `label == NULL`.

ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.

Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract

Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.

Major and minor rdev values are present also only when reparse buffer is

Pull vfs fixes from Christian Brauner:
 "vfs:

   - Ensure that iter_folioq_get_pages() advances to the next slot
     otherwise it will end up using the same folio with an out-of-bound
     offset.

  iomap:

   - Dont unshare delalloc extents which can't be reflinked, and thus
     can't be shared.

   - Constrain the file range passed to iomap_file_unshare() directly in
     iomap instead of requiring the callers to do it.

  netfs:

   - Use folioq_count instead of folioq_nr_slot to prevent an
     unitialized value warning in netfs_clear_buffer().

   - Fix missing wakeup after issuing writes by scheduling the write
     collector only if all the subrequest queues are empty and thus no
     writes are pending.

   - Fix two minor documentation bugs"

In sctp_listen_start() invoked by sctp_inet_listen(), it should set the
sk_state back to CLOSED if sctp_autobind() fails due to whatever reason.

Otherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)->reuse
is already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)->bind_hash will
be dereferenced as sk_state is LISTENING, which causes a crash as bind_hash
is NULL.

Add missing reg minItems as based on current binding document
only ethernet MAC IO space is a supported configuration.

There is a bug in schema, current examples contain 64-bit
addressing as well as 32-bit addressing. The schema validation
does pass incidentally considering one 64-bit reg address as
two 32-bit reg address entries. If we change axi_ethernet_eth1
example node reg addressing to 32-bit schema validation reports:

Documentation/devicetree/bindings/net/xlnx,axi-ethernet.example.dtb:
ethernet@40000000: reg: [[1073741824, 262144]] is too short

To fix it add missing reg minItems constraints and to make things clearer
stick to 32-bit addressing in examples.

Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Fix incorrect documentation in uapi/linux/netfilter/nf_tables.h
   regarding flowtable hooks, from Phil Sutter.

2) Fix nft_audit.sh selftests with newer nft binaries, due to different
   (valid) audit output, also from Phil.

3) Disable BH when duplicating packets via nf_dup infrastructure,
   otherwise race on nf_skb_duplicated for locally generated traffic.
   From Eric.

4) Missing return in callback of selftest C program, from zhang jiao.

File contents can only be shared (i.e. reflinked) below EOF, so it makes
no sense to try to unshare ranges beyond EOF.  Constrain the file range
parameters here so that we don't have to do that in the callers.

If unshare encounters a delalloc reservation in the srcmap, that means
that the file range isn't shared because delalloc reservations cannot be
reflinked.  Therefore, don't try to unshare them.

The MDS subsequently complains that the kernel client is late releasing
caps.

Approximately, a series of changes to this code by commits 49870056
("ceph: convert ceph_readpages to ceph_readahead"), 2de16041
("netfs: Change ->init_request() to return an error code") and
a5c9dc44 ("ceph: Make ceph_init_request() check caps on readahead")
resulted in subtle resource cleanup to be missed. The main culprit is
the change in error handling in 2de16041 which meant that a failure
in init_request() would no longer cause cleanup to be called. That
would prevent the ceph_put_cap_refs() call which would cleanup the
leaked cap ref.
