      dm thin: do not queue freed thin mapping for next stage processing · 00a0ea33
      Vallish Vaidyeshwara authored
      process_prepared_discard_passdown_pt1() should cleanup
      dm_thin_new_mapping in cases of error.
      dm_pool_inc_data_range() can fail trying to get a block reference:
      metadata operation 'dm_pool_inc_data_range' failed: error = -61
      When dm_pool_inc_data_range() fails, dm thin aborts current metadata
      transaction and marks pool as PM_READ_ONLY. Memory for thin mapping
      is released as well. However, current thin mapping will be queued
      onto next stage as part of queue_passdown_pt2() or passdown_endio().
      This dangling thin mapping memory when processed and accessed in
      next stage will lead to device mapper crashing.
      Code flow without fix:
      -> process_prepared_discard_passdown_pt1(m)
         -> dm_thin_remove_range()
         -> discard passdown
            --> passdown_endio(m) queues m onto next stage
         -> dm_pool_inc_data_range() fails, frees memory m
                  but does not remove it from next stage queue
      -> process_prepared_discard_passdown_pt2(m)
         -> processes freed memory m and crashes
      One such stack:
      Call Trace:
      [<ffffffffa037a46f>] dm_cell_release_no_holder+0x2f/0x70 [dm_bio_prison]
      [<ffffffffa039b6dc>] cell_defer_no_holder+0x3c/0x80 [dm_thin_pool]

      [<ffffffff81530b45>] ret_from_fork+0x25/0x30
      The fix is to first take the block ref count for discarded block and
      then do a passdown discard of this block. If block ref count fails,
      then bail out aborting current metadata transaction, mark pool as
      PM_READ_ONLY and also free current thin mapping memory (existing error
      handling code) without queueing this thin mapping onto next stage of
      processing. If block ref count succeeds, then passdown discard of this
      block. Discard callback of passdown_endio() will queue this thin mapping
      onto next stage of processing.
      Code flow with fix:
      -> process_prepared_discard_passdown_pt1(m)
         -> dm_thin_remove_range()
         -> dm_pool_inc_data_range()
            --> if fails, free memory m and bail out
         -> discard passdown
            --> passdown_endio(m) queues m onto next stage

      dm raid: fix oops on upgrading to extended superblock format · c4d097d1
      Heinz Mauelshagen authored
      When a RAID set was created on dm-raid version < 1.9.0 (old RAID
      superblock format), all of the new 1.9.0 members of the superblock are
      uninitialized (zero) -- including the device sectors member needed to
      support shrinking.
      All the other accesses to superblock fields new in 1.9.0 were reviewed
      and verified to be properly guarded against invalid use.  The 'sectors'
      member was the only one used when the superblock version is < 1.9.
      Don't access the superblock's >= 1.9.0 'sectors' member unconditionally.
      Also add respective comments.

      compiler, clang: properly override 'inline' for clang · 6d53cefb
      Linus Torvalds authored
      Commit abb2ea7d
       ("compiler, clang: suppress warning for unused
      static inline functions") just caused more warnings due to re-defining
      the 'inline' macro.
      So undef it before re-defining it, and also add the 'notrace' attribute
      like the gcc version that this is overriding does.
      Maybe this makes clang happier.

      This is due to async pf was injected to L2 which should be injected to L1,

      This patch fixes the hang by doing async pf when executing L1 guest.

      Pull UFS fixes from Al Viro:
       "This is just the obvious backport fodder; I'm pretty sure that there
        will be more - definitely so wrt performance and quite possibly
        correctness as well"
      * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
        ufs: we need to sync inode before freeing it
        excessive checks in ufs_write_failed() and ufs_evict_inode()
        ufs_getfrag_block(): we only grab ->truncate_mutex on block creation path

      Pull btrfs fixes from Chris Mason:
       "Some fixes that Dave Sterba collected.
        We've been hitting an early enospc problem on production machines that
        Omar tracked down to an old int->u64 mistake. I waited a bit on this
        pull to make sure it was really the problem from production, but it's
        on ~2100 hosts now and I think we're good.
        Omar also noticed a commit in the queue would make new early ENOSPC
        problems. I pulled that out for now, which is why the top three
        commits are younger than the rest.
        Otherwise these are all fixes, some explaining very old bugs that
        we've been poking at for a while"
