<title>kheaders: use `command -v` to test for existence of `cpio`</title>

<content type='text'>
Commit 13e1df09284d ("kheaders: explicitly validate existence of cpio
command") added an explicit check for `cpio` using `type`.

However, `type` in `dash` (which is used in some popular distributions
and base images as the shell script runner) prints the missing message
to standard output, and thus no error is printed:

    $ bash -c 'type missing &gt;/dev/null'
    bash: line 1: type: missing: not found
    $ dash -c 'type missing &gt;/dev/null'
    $

For instance, this issue may be seen by loongarch builders, given its
defconfig enables CONFIG_IKHEADERS since commit 9cc1df421f00 ("LoongArch:
Update Loongson-3 default config file").

Therefore, use `command -v` instead to have consistent behavior, and
take the chance to provide a more explicit error.

Fixes: 13e1df09284d ("kheaders: explicitly validate existence of cpio command")

Build environments might be running with different umask settings
resulting in indeterministic file modes for the files contained in
kheaders.tar.xz. The file itself is served with 444, i.e. world
readable. Archive the files explicitly with 744,a+X to improve
reproducibility across build environments.

--mode=0444 is not suitable as directories need to be executable. Also,
444 makes it hard to delete all the readonly files after extraction.

Pull probes fixes from Masami Hiramatsu:

 - uprobes: prevent mutex_lock() under rcu_read_lock().

   Recent changes moved uprobe_cpu_buffer preparation which involves
   mutex_lock(), under __uprobe_trace_func() which is called inside
   rcu_read_lock().

   Fix it by moving uprobe_cpu_buffer preparation outside of
   __uprobe_trace_func()

 - kprobe-events: handle the error case of btf_find_struct_member()

We have seen an influx of syzkaller reports where a BPF program attached to
a tracepoint triggers a locking rule violation by performing a map_delete
on a sockmap/sockhash.

We don't intend to support this artificial use scenario. Extend the
existing verifier allowed-program-type check for updating sockmap/sockhash
to also cover deleting from a map.

From now on only BPF programs which were previously allowed to update
sockmap/sockhash can delete from these map types.

Pull vfs fixes from Christian Brauner:

 - Fix io_uring based write-through after converting cifs to use the
   netfs library

 - Fix aio error handling when doing write-through via netfs library

 - Fix performance regression in iomap when used with non-large folio
   mappings

 - Fix signalfd error code

 - Remove obsolete comment in signalfd code

 - Fix async request indication in netfs_perform_write() by raising
   BDP_ASYNC when IOCB_NOWAIT is set

 - Yield swap device immediately to prevent spurious EBUSY errors

 - Don't cross a .backup mountpoint from backup volumes in afs to avoid
   infinite loops

 - Fix a race between umount and async request completion in 9p after 9p
   was converted to use the netfs library

* tag 'vfs-6.10-rc2.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  netfs, 9p: Fix race between umount and async request completion
  afs: Don't cross .backup mountpoint from backup volume
  swap: yield device immediately
  netfs: Fix setting of BDP_ASYNC from iocb flags
  signalfd: drop an obsolete comment
  signalfd: fix error return code
  iomap: fault in smaller chunks for non-large folio mappings
  filemap: add helper mapping_max_folio_size()
  netfs: Fix AIO error handling when doing write-through
  netfs: Fix io_uring based write-through

<title>tracing/probes: fix error check in parse_btf_field()</title>

btf_find_struct_member() might return NULL or an error via the
ERR_PTR() macro. However, its caller in parse_btf_field() only checks
for the NULL condition. Fix this by using IS_ERR() and returning the
error up the stack.
