      Pull tracing fixes from Steven Rostedt::
       "Eventfs fixes:
      
         - With the usage of simple_recursive_remove() recommended by Al Viro,
           the code should not be calling "d_invalidate()" itself. Doing so is
           causing crashes. The code was calling d_invalidate() on the race of
           trying to look up a file while the parent was being deleted. This
           was detected, and the added dentry was having d_invalidate() called
           on it, but the deletion of the directory was also calling
           d_invalidate() on that same dentry.
      
         - A fix to not free the eventfs_inode (ei) until the last dput() was
           called on its ei->dentry made the ei->dentry exist even after it
           was marked for free by setting the ei->is_freed. But code elsewhere
           still was checking if ei->dentry was NULL if ei->is_freed is set
           and would trigger WARN_ON if that was the case. That's no longer
           true and there should not be any warnings when it is true.
      
         - Use GFP_NOFS for allocations done under eventfs_mutex. The
           eventfs_mutex can be taken on file system reclaim, make sure that
           allocations done under that mutex do not trigger file system
           reclaim.
      
         - Clean up code by moving the taking of inode_lock out of the helper
           functions and into where they are needed, and not use the parameter
           to know to take it or not. It must always be held but some callers
           of the helper function have it taken when they were called.
      
         - Warn if the inode_lock is not held in the helper functions.
      
         - Warn if eventfs_start_creating() is called without a parent. As
           eventfs is underneath tracefs, all files created will have a parent
           (the top one will have a tracefs parent).
      
        Tracing update:
      
         - Add Mathieu Desnoyers as an official reviewer of the tracing subsystem"

        Due to not being correctly aligned at link & load time they can
        trigger unnecessarily the kernel unaligned exception handler at
        runtime. While at it, I switched the bug table to use relative
        addresses which reduces the size of the table by half on 64-bit.
      
        We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
        from HP-UX, which now trigger build-issues with glibc. We can simply
        remove them.
      
        Most of the patches are tagged for stable kernel series.

      Pull vfs fixes from Christian Brauner:
      
       - Avoid calling back into LSMs from vfs_getattr_nosec() calls.
      
         IMA used to query inode properties accessing raw inode fields without
         dedicated helpers. That was finally fixed a few releases ago by
         forcing IMA to use vfs_getattr_nosec() helpers.
      
         The goal of the vfs_getattr_nosec() helper is to query for attributes
         without calling into the LSM layer which would be quite problematic
         because incredibly IMA is called from __fput()...
      
           __fput()
             -> ima_file_free()
      
         What it does is to call back into the filesystem to update the file's
         IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
         that IMA didn't handle stacking filesystems such as overlayfs
         correctly. So the switch to vfs_getattr_nosec() is quite correct. But
         the switch to vfs_getattr_nosec() revealed another bug when used on
         stacking filesystems:
      
           __fput()
             -> ima_file_free()
                -> vfs_getattr_nosec()
                   -> i_op->getattr::ovl_getattr()
                      -> vfs_getattr()
                         -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
                            -> security_inode_getattr() # calls back into LSMs
      
         Now, if that __fput() happens from task_work_run() of an exiting task
         current->fs and various other pointer could already be NULL. So
         anything in the LSM layer relying on that not being NULL would be
         quite surprised.
      
         Fix that by passing the information that this is a security request
         through to the stacking filesystem by adding a new internal
         ATT_GETATTR_NOSEC flag. Now the callchain becomes:
      
           __fput()
             -> ima_file_free()
                -> vfs_getattr_nosec()
                   -> i_op->getattr::ovl_getattr()
                      -> if (AT_GETATTR_NOSEC)
                                vfs_getattr_nosec()
                         else
                                vfs_getattr()
                         -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
      
       - Fix a bug introduced with the iov_iter rework from last cycle.
      
         This broke /proc/kcore by copying too much and without the correct
         offset.
      
       - Add a missing NULL check when allocating the root inode in
         autofs_fill_super().
      
       - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
         the block device pseudo filesystem.
      
         Stable writes used to be a superblock flag only, making it a per
         filesystem property. Add an additional AS_STABLE_WRITES mapping flag
         to allow for fine-grained control.
      
       - Ensure that offset_iterate_dir() returns 0 after reaching the end of
         a directory so it adheres to getdents() convention.

      afs: Fix file locking on R/O volumes to operate in local mode · b590eb41
      David Howells authored
      AFS doesn't really do locking on R/O volumes as fileservers don't maintain
      state with each other and thus a lock on a R/O volume file on one
      fileserver will not be be visible to someone looking at the same file on
      another fileserver.
      
      Further, the server may return an error if you try it.
      
      Fix this by doing what other AFS clients do and handle filelocking on R/O
      volume files entirely within the client and don't touch the server.

      Make AFS return error ENOENT if no cell SRV or AFSDB DNS record (or

      lockdep: Fix block chain corruption · bca4104b
      Peter Zijlstra authored
      Kent reported an occasional KASAN splat in lockdep. Mark then noted:
      
      > I suspect the dodgy access is to chain_block_buckets[-1], which hits the last 4
      > bytes of the redzone and gets (incorrectly/misleadingly) attributed to
      > nr_large_chain_blocks.
      
      That would mean @size == 0, at which point size_to_bucket() returns -1
      and the above happens.
      
      alloc_chain_hlocks() has 'size - req', for the first with the
      precondition 'size >= rq', which allows the 0.
      
      This code is trying to split a block, del_chain_block() takes what we
      need, and add_chain_block() puts back the remainder, except in the
      above case the remainder is 0 sized and things go sideways.
      
      Fixes: 810507fe ("locking/lockdep: Reuse freed chain_hlocks entries")
