      sysctl: treewide: constify the ctl_table argument of proc_handlers · 78eb4ea2
      Joel Granados authored 
      const qualify the struct ctl_table argument in the proc_handler function
signatures. This is a prerequisite to moving the static ctl_table
structs into .rodata data which will ensure that proc_handler function
pointers cannot be modified.

This patch has been generated by the following coccinelle script:

  @@

  int func(
  - struct ctl_table *
  + const struct ctl_table *
    ,int write, void *buffer, size_t *lenp, loff_t *ppos);

```

* Code formatting was adjusted in xfs_sysctl.c to comply with code
  conventions. The xfs_stats_clear_proc_handler,
  xfs_panic_mask_proc_handler and xfs_deprecated_dointvec_minmax where
  adjusted.

* The ctl_table argument in proc_watchdog_common was const qualified.
  This is called from a proc_handler itself and is calling back into
  another proc_handler, making it necessary to change it as part of the
  proc_handler migration.

      Merge tag 'random-6.11-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random · 7a3fad30
      Linus Torvalds authored 
      Pull random number generator updates from Jason Donenfeld:
 "This adds getrandom() support to the vDSO.

  First, it adds a new kind of mapping to mmap(2), MAP_DROPPABLE, which
  lets the kernel zero out pages anytime under memory pressure, which
  enables allocating memory that never gets swapped to disk but also
  doesn't count as being mlocked.

  Then, the vDSO implementation of getrandom() is introduced in a
  generic manner and hooked into random.c.

  Next, this is implemented on x86. (Also, though it's not ready for
  this pull, somebody has begun an arm64 implementation already)

  Finally, two vDSO selftests are added.

  There are also two housekeeping cleanup commits"

      Linus Torvalds authored 
      Pull vfs fixes from Christian Brauner:
 "VFS:

   - The new 64bit mount ids start after the old mount id, i.e., at the
     first non-32 bit value. However, we started counting one id too
     late and thus lost 4294967296 as the first valid id. Fix that.

   - Update a few comments on some vfs_*() creation helpers.

   - Move copying of the xattr name out from the locks required to start
     a filesystem write.

   - Extend the filelock lock UAF fix to the compat code as well.

   - Now that we added the ability to look up an inode under RCU it's
     possible that lockless hash lookup can find and lock an inode after
     it gets I_FREEING set. It then waits until inode teardown in
     evict() is finished.

     The flag however is still set after evict() has woken up all
     waiters. If the inode lock is taken late enough on the waiting side
     after hash removal and wakeup happened the waiting thread will
     never be woken.

     Before RCU based lookup this was synchronized via the
     inode_hash_lock. But since unhashing requires the inode lock as
     well we can check whether the inode is unhashed while holding inode
     lock even without holding inode_hash_lock.

  pidfd:

   - The nsproxy structure contains nearly all of the namespaces
     associated with a task. When a namespace type isn't supported
     nsproxy might contain a NULL pointer or always point to the initial
     namespace type. The logic isn't consistent. So when deriving
     namespace fds we need to ensure that the namespace type is
     supported.

     First, so that we don't risk dereferncing NULL pointers. The
     correct bigger fix would be to change all namespaces to always set
     a valid namespace pointer in struct nsproxy independent of whether
     or not it is compiled in. But that requires quite a few changes.

     Second, so that we don't allow deriving namespace fds when the
     namespace type doesn't exist and thus when they couldn't also be
     derived via /proc/self/ns/.

   - Add missing selftests for the new pidfd ioctls to derive namespace
     fds. This simply extends the already existing testsuite.

  netfs:

   - Fix debug logging and fix kconfig variable name so it actually
     works.

   - Fix writeback that goes both to the server and cache. The streams
     are only activated once a subreq is added. When a server write
     happens the subreq doesn't need to have finished by the time the
     cache write is started. If the server write has already finished by
     the time the cache write is about to start the cache write will
     operate on a folio that might already have been reused. Fix this by
     preactivating the cache write.

   - Limit cachefiles subreq size for cache writes to MAX_RW_COUNT"

      hostfs: fix folio conversion · e44be002
      Linus Torvalds authored 
      Commit e3ec0fe9 ("hostfs: Convert hostfs_read_folio() to use a
folio") simplified hostfs_read_folio(), but in the process of converting
to using folios natively also mis-used the folio_zero_tail() function
due to the very confusing API of that function.

Very arguably it's folio_zero_tail() API itself that is buggy, since it
would make more sense (and the documentation kind of implies) that the
third argument would be the pointer to the beginning of the folio
buffer.

But no, the third argument to folio_zero_tail() is where we should start
zeroing the tail (even if we already also pass in the offset separately
as the second argument).

So fix the hostfs caller, and we can leave any folio_zero_tail() sanity
cleanup for later.
