      由 Linus Torvalds 提交于 
      Pull vfs d_inode/d_flags memory ordering fixes from Al Viro:
 "Fallout from tree-wide audit for ->d_inode/->d_flags barriers use.
  Basically, the problem is that negative pinned dentries require
  careful treatment - unless ->d_lock is locked or parent is held at
  least shared, another thread can make them positive right under us.

  Most of the uses turned out to be safe - the main surprises as far as
  filesystems are concerned were

   - race in dget_parent() fastpath, that might end up with the caller
     observing the returned dentry _negative_, due to insufficient
     barriers. It is positive in memory, but we could end up seeing the
     wrong value of ->d_inode in CPU cache. Fixed.

   - manual checks that result of lookup_one_len_unlocked() is positive
     (and rejection of negatives). Again, insufficient barriers (we
     might end up with inconsistent observed values of ->d_inode and
     ->d_flags). Fixed by switching to a new primitive that does the
     checks itself and returns ERR_PTR(-ENOENT) instead of a negative
     dentry. That way we get rid of boilerplate converting negatives
     into ERR_PTR(-ENOENT) in the callers and have a single place to
     deal with the barrier-related mess - inside fs/namei.c rather than
     in every caller out there.

  The guts of pathname resolution *do* need to be careful - the race
  found by Ritesh is real, as well as several similar races.
  Fortunately, it turns out that we can take care of that with fairly
  local changes in there.

  The tree-wide audit had not been fun, and I hate the idea of repeating
  it. I think the right approach would be to annotate the places where
  we are _not_ guaranteed ->d_inode/->d_flags stability and have sparse
  catch regressions. But I'm still not sure what would be the least
  invasive way of doing that and it's clearly the next cycle fodder"

      Merge branch 'next.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs · b0d4beaa
      由 Linus Torvalds 提交于 
      Pull autofs updates from Al Viro:
 "autofs misuses checks for ->d_subdirs emptiness; the cursors are in
  the same lists, resulting in false negatives. It's not needed anyway,
  since autofs maintains counter in struct autofs_info, containing 0 for
  removed ones, 1 for live symlinks and 1 + number of children for live
  directories, which is precisely what we need for those checks.

  This series switches to use of that counter and untangles the crap
  around its uses (it needs not be atomic and there's a bunch of
  completely pointless "defensive" checks).

  This fell out of dcache_readdir work; the main point is to get rid of
  ->d_subdirs abuses in there. I've more followup cleanups, but I hadn't
  run those by Ian yet, so they can go next cycle"

      Merge branch 'pipe-rework' (patches from David Howells) · da73fcd8
      由 Linus Torvalds 提交于 
      Merge two fixes for the pipe rework from David Howells:
 "Here are a couple of patches to fix bugs syzbot found in the pipe
  changes:

   - An assertion check will sometimes trip when polling a pipe because
     the ring size and indices used are approximate and may be being
     changed simultaneously.

     An equivalent approximate calculation was done previously, but
     without the assertion check, so I've just dropped the check. To
     make it accurate, the pipe mutex would need to be taken or the spin
     lock could be used - but usage of the spinlock would need to be
     rolled out into splice, iov_iter and other places for that.

   - The index mask and the max_usage values cannot be cached across
     pipe_wait() as F_SETPIPE_SZ could have been called during the wait.
     This can cause pipe_write() to break"

* pipe-rework:
  pipe: Fix missing mask update after pipe_wait()
  pipe: Remove assertion from pipe_poll()

      pipe: Fix missing mask update after pipe_wait() · 8f868d68
      由 David Howells 提交于 
      Fix pipe_write() to not cache the ring index mask and max_usage as their
values are invalidated by calling pipe_wait() because the latter
function drops the pipe lock, thereby allowing F_SETPIPE_SZ change them.
Without this, pipe_write() may subsequently miscalculate the array
indices and pipe fullness, leading to an oops like the following:

  BUG: KASAN: slab-out-of-bounds in pipe_write+0xc25/0xe10 fs/pipe.c:481

This is not a problem for pipe_read() as the mask is recalculated on
each pass of the loop, after pipe_wait() has been called.

      pipe: Remove assertion from pipe_poll() · 8c7b8c34
      由 David Howells 提交于 
      An assertion check was added to pipe_poll() to make sure that the ring
occupancy isn't seen to overflow the ring size.  However, since no locks
are held when the three values are read, it is possible for F_SETPIPE_SZ
to intervene and muck up the calculation, thereby causing the oops.

Fix this by simply removing the assertion and accepting that the
calculation might be approximate.

Note that the previous code also had a similar issue, though there was
no assertion check, since the occupancy counter and the ring size were
not read with a lock held, so it's possible that the poll check might
have malfunctioned then too.

Also wake up all the waiters so that they can reissue their checks if
there was a competing read or write.
