       "orangefs: posix open permission checking...
      
        Orangefs has no open, and orangefs checks file permissions on each
        file access. Posix requires that file permissions be checked on open
        and nowhere else. Orangefs-through-the-kernel needs to seem posix
        compliant.
      
        The VFS opens files, even if the filesystem provides no method. We can
        see if a file was successfully opened for read and or for write by
        looking at file->f_mode.
      
        When writes are flowing from the page cache, file is no longer
        available. We can trust the VFS to have checked file->f_mode before
        writing to the page cache.
      
        The mode of a file might change between when it is opened and IO
        commences, or it might be created with an arbitrary mode.
      
        We'll make sure we don't hit EACCES during the IO stage by using
        UID 0"
      
      [ This is "posixish", but not a great solution in the long run, since a
        proper secure network server shouldn't really trust the client like this.
        But proper and secure POSIX behavior requires an open method and a
        resulting cookie for IO of some kind, or similar.    - Linus ]

      pipe: fix incorrect caching of pipe state over pipe_wait() · ec057595
      Linus Torvalds authored
      Similarly to commit 8f868d68
      
       ("pipe: Fix missing mask update after
      pipe_wait()") this fixes a case where the pipe rewrite ended up caching
      the pipe state incorrectly over a pipe lock drop event.
      
      It wasn't quite as obvious, because you needed to splice data from a
      pipe to a file, which is a fairly unusual operation, but it's completely
      wrong.
      
      Make sure we load the pipe head/tail/size information only after we've
      waited for there to be data in the pipe.
      
      While in that file, also make one of the splice helper functions use the
      canonical arghument order for pipe_empty().  That's syntactic - pipe
      emptiness is just that head and tail are equal, and thus mixing up head
      and tail doesn't really matter.  It's still wrong, though.

      Pull more block and io_uring updates from Jens Axboe:
       "I wasn't expecting this to be so big, and if I was, I would have used
        separate branches for this. Going forward I'll be doing separate
        branches for the current tree, just like for the next kernel version
        tree. In any case, this contains:
      
         - Series from Christoph that fixes an inherent race condition with
           zoned devices and revalidation.
      
         - null_blk zone size fix (Damien)
      
         - Fix for a regression in this merge window that caused busy spins by
           sending empty disk uevents (Eric)
      
         - Fix for a regression in this merge window for bfq stats (Hou)
      
         - Fix for io_uring creds allocation failure handling (me)
      
         - io_uring -ERESTARTSYS send/recvmsg fix (me)
      
         - Series that fixes the need for applications to retain state across
           async request punts for io_uring. This one is a bit larger than I
           would have hoped, but I think it's important we get this fixed for
           5.5.
      
         - connect(2) improvement for io_uring, handling EINPROGRESS instead
           of having applications needing to poll for it (me)
      
         - Have io_uring use a hash for poll requests instead of an rbtree.
           This turned out to work much better in practice, so I think we
           should make the switch now. For some workloads, even with a fair
           amount of cancellations, the insertion sort is just too expensive.
           (me)
      
         - Various little io_uring fixes (me, Jackie, Pavel, LimingWu)
      
         - Fix for brd unaligned IO, and a warning for the future (Ming)
      
         - Fix for a bio integrity data leak (Justin)
      
         - bvec_iter_advance() improvement (Pavel)
      
         - Xen blkback page unmap fix (SeongJae)
      
        The major items in here are all well tested, and on the liburing side
        we continue to add regression and feature test cases. We're up to 50
        topic cases now, each with anywhere from 1 to more than 10 cases in
        each"

      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"
