      assoc_array: Fix BUG_ON during garbage collect · d1dc8776
      Stephen Brennan authored
      A rare BUG_ON triggered in assoc_array_gc:
      
          [3430308.818153] kernel BUG at lib/assoc_array.c:1609!
      
      Which corresponded to the statement currently at line 1593 upstream:
      
          BUG_ON(assoc_array_ptr_is_meta(p));
      
      Using the data from the core dump, I was able to generate a userspace
      reproducer[1] and determine the cause of the bug.
      
      [1]: https://github.com/brenns10/kernel_stuff/tree/master/assoc_array_gc
      
      After running the iterator on the entire branch, an internal tree node
      looked like the following:
      
          NODE (nr_leaves_on_branch: 3)
            SLOT [0] NODE (2 leaves)
            SLOT [1] NODE (1 leaf)
            SLOT [2..f] NODE (empty)
      
      In the userspace reproducer, the pr_devel output when compressing this
      node was:
      
          -- compress node 0x5607cc089380 --
          free=0, leaves=0
          [0] retain node 2/1 [nx 0]
          [1] fold node 1/1 [nx 0]
          [2] fold node 0/1 [nx 2]
          [3] fold node 0/2 [nx 2]
          [4] fold node 0/3 [nx 2]
          [5] fold node 0/4 [nx 2]
          [6] fold node 0/5 [nx 2]
          [7] fold node 0/6 [nx 2]
          [8] fold node 0/7 [nx 2]
          [9] fold node 0/8 [nx 2]
          [10] fold node 0/9 [nx 2]
          [11] fold node 0/10 [nx 2]
          [12] fold node 0/11 [nx 2]
          [13] fold node 0/12 [nx 2]
          [14] fold node 0/13 [nx 2]
          [15] fold node 0/14 [nx 2]
          after: 3
      
      At slot 0, an internal node with 2 leaves could not be folded into the
      node, because there was only one available slot (slot 0). Thus, the
      internal node was retained. At slot 1, the node had one leaf, and was
      able to be folded in successfully. The remaining nodes had no leaves,
      and so were removed. By the end of the compression stage, there were 14
      free slots, and only 3 leaf nodes. The tree was ascended and then its
      parent node was compressed. When this node was seen, it could not be
      folded, due to the internal node it contained.
      
      The invariant for compression in this function is: whenever
      nr_leaves_on_branch < ASSOC_ARRAY_FAN_OUT, the node should contain all
      leaf nodes. The compression step currently cannot guarantee this, given
      the corner case shown above.
      
      To fix this issue, retry compression whenever we have retained a node,
      and yet nr_leaves_on_branch < ASSOC_ARRAY_FAN_OUT. This second
      compression will then allow the node in slot 1 to be folded in,
      satisfying the invariant. Below is the output of the reproducer once the
      fix is applied:
      
          -- compress node 0x560e9c562380 --
          free=0, leaves=0
          [0] retain node 2/1 [nx 0]
          [1] fold node 1/1 [nx 0]
          [2] fold node 0/1 [nx 2]
          [3] fold node 0/2 [nx 2]
          [4] fold node 0/3 [nx 2]
          [5] fold node 0/4 [nx 2]
          [6] fold node 0/5 [nx 2]
          [7] fold node 0/6 [nx 2]
          [8] fold node 0/7 [nx 2]
          [9] fold node 0/8 [nx 2]
          [10] fold node 0/9 [nx 2]
          [11] fold node 0/10 [nx 2]
          [12] fold node 0/11 [nx 2]
          [13] fold node 0/12 [nx 2]
          [14] fold node 0/13 [nx 2]
          [15] fold node 0/14 [nx 2]
          internal nodes remain despite enough space, retrying
          -- compress node 0x560e9c562380 --
          free=14, leaves=1
          [0] fold node 2/15 [nx 0]

      afs: Fix infinite loop found by xfstest generic/676 · 17eabd42
      David Howells authored
      In AFS, a directory is handled as a file that the client downloads and
      parses locally for the purposes of performing lookup and getdents
      operations.  The in-kernel afs filesystem has a number of functions that
      do this.
      
      A directory file is arranged as a series of 2K blocks divided into
      32-byte slots, where a directory entry occupies one or more slots, plus
      each block starts with one or more metadata blocks.
      
      When parsing a block, if the last slots are occupied by a dirent that
      occupies more than a single slot and the file position points at a slot
      that's not the initial one, the logic in afs_dir_iterate_block() that
      skips over it won't advance the file pointer to the end of it.  This
      will cause an infinite loop in getdents() as it will keep retrying that
      block and failing to advance beyond the final entry.
      
      Fix this by advancing the file pointer if the next entry will be beyond
      it when we skip a block.
      
      This was found by the generic/676 xfstest but can also be triggered with
      something like:
      
      	~/xfstests-dev/src/t_readdir_3 /xfstest.test/z 4000 1

       "In this round, we've refactored the existing atomic write support
        implemented by in-memory operations to have storing data in disk
        temporarily, which can give us a benefit to accept more atomic writes.
      
        At the same time, we removed the existing volatile write support.
      
        We've also revisited the file pinning and GC flows and found some
        corner cases which contributeed abnormal system behaviours.
      
        As usual, there're several minor code refactoring for readability,
        sanity check, and clean ups.
      
        Enhancements:
      
         - allow compression for mmap files in compress_mode=user
      
         - kill volatile write support

      dm verity: set DM_TARGET_IMMUTABLE feature flag · 4caae584
      Sarthak Kukreti authored
      The device-mapper framework provides a mechanism to mark targets as
      immutable (and hence fail table reloads that try to change the target
      type). Add the DM_TARGET_IMMUTABLE flag to the dm-verity target's
      feature flags to prevent switching the verity target with a different
      target type.

      dm table: fix dm_table_supports_poll to return false if no data devices · 9571f829
      Mike Snitzer authored
      It was reported that the "generic/250" test in xfstests (which uses
      the dm-error target) demonstrates a regression where the kernel
      crashes in bioset_exit().
      
      Since commit cfc97abc ("dm: conditionally enable
      BIOSET_PERCPU_CACHE for dm_io bioset") the bioset_init() for the dm_io
      bioset will setup the bioset's per-cpu alloc cache if all devices have
      QUEUE_FLAG_POLL set.
      
      But there was an bug where a target that doesn't have any data devices
      (and that doesn't even set the .iterate_devices dm target callback)
      will incorrectly return true from dm_table_supports_poll().
      
      Fix this by updating dm_table_supports_poll() to follow dm-table.c's
      well-worn pattern for testing that _all_ targets in a DM table do in
      fact have underlying devices that set QUEUE_FLAG_POLL.
      
      NOTE: An additional block fix is still needed so that
      bio_alloc_cache_destroy() clears the bioset's ->cache member.
      Otherwise, a DM device's table reload that transitions the DM device's
      bioset from using a per-cpu alloc cache to _not_ using one will result
      in bioset_exit() crashing in bio_alloc_cache_destroy() because dm's
      dm_io bioset ("io_bs") was left with a stale ->cache member.
      
      Fixes: cfc97abc ("dm: conditionally enable BIOSET_PERCPU_CACHE for dm_io bioset")
