      Pull infiniband fixes from Doug Ledford:
       "It's late in the game, I know, but these fixes seemed important enough
        to warrant a late pull request.  They all involve oopses or use after
        frees or corruptions.
      
        Six serious fixes:
      
         - Hold the mutex around the find and corresponding update of our gid
      
         - The ifa list is rcu protected, copy its contents under rcu to avoid
           using a freed structure
      
         - On error, netdev might be null, so check it before trying to
           release it
      
         - On init, if workqueue alloc fails, fail init
      
         - The new demux patches exposed a bug in mlx5 and ipath drivers, we
           need to use the payload P_Key to determine the P_Key the packet
           arrived on because the hardware doesn't tell us the truth
      
         - Due to a couple convoluted error flows, it is possible for the CM
           to trigger a use_after_free and a double_free of rb nodes.  Add two
           checks to prevent that.  This code has worked for 10+ years.  It is
           likely that some of the recent changes have caused this issue to
           surface.  The current patch will protect us from nasty events for
           now while we track down why this is just now showing up"

      dm cache: the CLEAN_SHUTDOWN flag was not being set · 3201ac45
      Joe Thornber authored
      If the CLEAN_SHUTDOWN flag is not set when a cache is loaded then all cache
      blocks are marked as dirty and a full writeback occurs.
      
      __commit_transaction() is responsible for setting/clearing
      CLEAN_SHUTDOWN (based the flags_mutator that is passed in).
      
      Fix this issue, of the cache's on-disk flags being wrong, by making sure
      __commit_transaction() does not reset the flags after the mutator has
      altered the flags in preparation for them being serialized to disk.
      
      before:
      
      sb_flags = mutator(le32_to_cpu(disk_super->flags));
      disk_super->flags = cpu_to_le32(sb_flags);
      disk_super->flags = cpu_to_le32(cmd->flags);
      
      after:
      
      disk_super->flags = cpu_to_le32(cmd->flags);
      sb_flags = mutator(le32_to_cpu(disk_super->flags));
      disk_super->flags = cpu_to_le32(sb_flags);

      Mike Snitzer authored
      btree_split_beneath()'s error path had an outstanding FIXME that speaks
      directly to the potential for _not_ cleaning up a previously allocated
      bufio-backed block.
      
      Fix this by releasing the previously allocated bufio block using

      dm btree remove: fix a bug when rebalancing nodes after removal · 2871c69e
      Joe Thornber authored
      Commit 4c7e3093 ("dm btree remove: fix bug in redistribute3") wasn't
      a complete fix for redistribute3().
      
      The redistribute3 function takes 3 btree nodes and shares out the entries
      evenly between them.  If the three nodes in total contained
      (MAX_ENTRIES * 3) - 1 entries between them then this was erroneously getting
      rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 1) in
      the center.
      
      Fix this issue by being more careful about calculating the target number
      of entries for the left and right nodes.

      rbd: prevent kernel stack blow up on rbd map · 6d69bb53
      Ilya Dryomov authored
      Mapping an image with a long parent chain (e.g. image foo, whose parent
      is bar, whose parent is baz, etc) currently leads to a kernel stack
      overflow, due to the following recursion in the reply path:
      
        rbd_osd_req_callback()
          rbd_obj_request_complete()
            rbd_img_obj_callback()
              rbd_img_parent_read_callback()
                rbd_obj_request_complete()
                  ...
      
      Limit the parent chain to 16 images, which is ~5K worth of stack.  When
      the above recursion is eliminated, this limit can be lifted.

      rbd: don't leak parent_spec in rbd_dev_probe_parent() · 1f2c6651
      Ilya Dryomov authored
      Currently we leak parent_spec and trigger a "parent reference
      underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails.
      The problem is we take the !parent out_err branch and that only drops
      refcounts; parent_spec that would've been freed had we called
      rbd_dev_unparent() remains and triggers rbd_warn() in
      rbd_dev_parent_put() - at that point we have parent_spec != NULL and
      parent_ref == 0, so counter ends up being -1 after the decrement.
      
      Redo rbd_dev_probe_parent() to fix this.

       "Running tests on other changes, the system locked up due to lots of
        warnings.  It was caused by the stack tracer triggering a warning
        about using rcu_dereference() when RCU was not watching.  This can
        happen due to the fact that the stack tracer uses the function tracer
        to check each function, and there are functions that may be called and
        traced when RCU stopped watching.  Namely when a function is called
        just before going idle or to userspace and after RCU stopped watching
        that current CPU.
      
        The first patch makes sure that RCU is watching when the stack tracer
        uses RCU.  The second patch is to make sure that the stack tracer does
        not get called by functions in NMI, as it's not NMI safe"

      dlm_lockres_put will call dlm_lockres_release if it is the last
      reference, and then it may call dlm_print_one_lock_resource and
      take lockres spinlock.
      
      So unlock lockres spinlock before dlm_lockres_put to avoid deadlock.

      lib/Kconfig.debug: disable -Wframe-larger-than warnings with KASAN=y · 3f181b4d
      Andrey Ryabinin authored
      When the kernel compiled with KASAN=y, GCC adds redzones for each
      variable on stack.  This enlarges function's stack frame and causes:
      
      	'warning: the frame size of X bytes is larger than Y bytes'
      
      The worst case I've seen for now is following:
      
         ../net/wireless/nl80211.c: In function `nl80211_send_wiphy':
         ../net/wireless/nl80211.c:1731:1: warning: the frame size of 5448 bytes is larger than 2048 bytes [-Wframe-larger-than=]
      
      That kind of warning becomes useless with KASAN=y.  It doesn't
      necessarily indicate that there is some problem in the code, thus we
      should turn it off.
      
      (The KASAN=y stack size in increased from 16k to 32k for this reason)

      mm: make sendfile(2) killable · 296291cd
      Jan Kara authored
      Currently a simple program below issues a sendfile(2) system call which
      takes about 62 days to complete in my test KVM instance.
      
              int fd;
              off_t off = 0;
      
              fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644);
              ftruncate(fd, 2);
              lseek(fd, 0, SEEK_END);
              sendfile(fd, fd, &off, 0xfffffff);
      
      Now you should not ask kernel to do a stupid stuff like copying 256MB in
      2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin
      should have a way to stop you.
      
      We actually do have a check for fatal_signal_pending() in
      generic_perform_write() which triggers in this path however because we
      always succeed in writing something before the check is done, we return
      value > 0 from generic_perform_write() and thus the information about
      signal gets lost.
      
      Fix the problem by doing the signal check before writing anything.  That
      way generic_perform_write() returns -EINTR, the error gets propagated up
      and the sendfile loop terminates early.

      thp: use is_zero_pfn() only after pte_present() check · 47aee4d8
      Minchan Kim authored
      Use is_zero_pfn() on pteval only after pte_present() check on pteval
      (It might be better idea to introduce is_zero_pte() which checks
      pte_present() first).
      
      Otherwise when working on a swap or migration entry and if pte_pfn's
      result is equal to zero_pfn by chance, we lose user's data in
      __collapse_huge_page_copy().  So if you're unlucky, the application
      segfaults and finally you could see below message on exit:

      Oleg Nesterov authored
      call_usermodehelper_exec_sync() does fork() + wait() with "unignored"
      SIGCHLD.  What we have missed is that this worker thread can have other
      children previously forked by call_usermodehelper_exec_work() without
      UMH_WAIT_PROC.  If such a child exits in between it becomes a zombie
      because auto-reaping only works if SIGCHLD is ignored, and nobody can
      reap it (unless/until this worker thread exits too).
      
      Change the !UMH_WAIT_PROC case to use CLONE_PARENT.
      
      Note: this is only first step.  All PF_KTHREAD tasks, even created by
      kernel_thread() should have ->parent == kthreadd by default.
