       "A small crop of lockdep, sleeping while atomic, and other fixes /
        band-aids in advance of the full-blown reworks targeting the next
        merge window. The largest change here is "libnvdimm: fix blk free
        space accounting" which deletes a pile of buggy code that better
        testing would have caught before merging. The next change that is
        borderline too big for a late rc is switching the device-dax locking
        from rcu to srcu, I couldn't think of a smaller way to make that fix.
      
        The __copy_user_nocache fix will have a full replacement in 4.12 to
        move those pmem special case considerations into the pmem driver. The
        "libnvdimm: band aid btt vs clear poison locking" commit admits that
        our error clearing support for btt went in broken, so we just disable
        it in 4.11 and -stable. A replacement / full fix is in the pipeline
        for 4.12
      
        Some of these would have been caught earlier had DEBUG_ATOMIC_SLEEP
        been enabled on my development station. I wonder if we should have:
      
            config DEBUG_ATOMIC_SLEEP
              default PROVE_LOCKING
      
        ...since I mistakenly thought I got both with PROVE_LOCKING=y.
      
        These have received a build success notification from the 0day robot,
        and some have appeared in a -next release with no reported issues"

      vfs: don't do RCU lookup of empty pathnames · c0eb027e
      Linus Torvalds authored
      Normal pathname lookup doesn't allow empty pathnames, but using
      AT_EMPTY_PATH (with name_to_handle_at() or fstatat(), for example) you
      can trigger an empty pathname lookup.
      
      And not only is the RCU lookup in that case entirely unnecessary
      (because we'll obviously immediately finalize the end result), it is
      actively wrong.
      
      Why? An empth path is a special case that will return the original
      'dirfd' dentry - and that dentry may not actually be RCU-free'd,
      resulting in a potential use-after-free if we were to initialize the
      path lazily under the RCU read lock and depend on complete_walk()
      finalizing the dentry.
      
      Found by syzkaller and KASAN.

      parisc: fix bugs in pa_memcpy · 409c1b25
      Mikulas Patocka authored
      The patch 554bfece ("parisc: Fix access
      fault handling in pa_memcpy()") reimplements the pa_memcpy function.
      Unfortunatelly, it makes the kernel unbootable. The crash happens in the
      function ide_complete_cmd where memcpy is called with the same source
      and destination address.
      
      This patch fixes a few bugs in pa_memcpy:
      
      * When jumping to .Lcopy_loop_16 for the first time, don't skip the
        instruction "ldi 31,t0" (this bug made the kernel unbootable)
      * Use the COND macro when comparing length, so that the comparison is
        64-bit (a theoretical issue, in case the length is greater than
        0xffffffff)
      * Don't use the COND macro after the "extru" instruction (the PA-RISC
        specification says that the upper 32-bits of extru result are undefined,
        although they are set to zero in practice)
      * Fix exception addresses in .Lcopy16_fault and .Lcopy8_fault
      * Rename .Lcopy_loop_4 to .Lcopy_loop_8 (so that it is consistent with
        .Lcopy8_fault)

      ftrace: Fix removing of second function probe · 82cc4fc2
      Steven Rostedt (VMware) authored
      When two function probes are added to set_ftrace_filter, and then one of
      them is removed, the update to the function locations is not performed, and
      the record keeping of the function states are corrupted, and causes an
      ftrace_bug() to occur.
      
      This is easily reproducable by adding two probes, removing one, and then
      adding it back again.

      block: fix bio_will_gap() for first bvec with offset · 5a8d75a1
      Ming Lei authored
      Commit 729204ef("block: relax check on sg gap") allows us to merge
      bios, if both are physically contiguous.  This change can merge a huge
      number of small bios, through mkfs for example, mkfs.ntfs running time
      can be decreased to ~1/10.
      
      But if one rq starts with a non-aligned buffer (the 1st bvec's bv_offset
      is non-zero) and if we allow the merge, it is quite difficult to respect
      sg gap limit, especially the max segment size, or we risk having an
      unaligned virtual boundary.  This patch tries to avoid the issue by
      disallowing a merge, if the req starts with an unaligned buffer.
      
      Also add comments to explain why the merged segment can't end in
      unaligned virt boundary.

      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for your net tree,
      they are:
      
      1) Missing TCP header sanity check in TCPMSS target, from Eric Dumazet.
      
      2) Incorrect event message type for related conntracks created via
         ctnetlink, from Liping Zhang.
      
      3) Fix incorrect rcu locking when handling helpers from ctnetlink,
         from Gao feng.
      
      4) Fix missing rcu locking when updating helper, from Liping Zhang.
      
      5) Fix missing read_lock_bh when iterating over list of device addresses
         from TPROXY and redirect, also from Liping.
      
      6) Fix crash when trying to dump expectations from conntrack with no
         helper via ctnetlink, from Liping.
      
      7) Missing RCU protection to expecation list update given ctnetlink
         iterates over the list under rcu read lock side, from Liping too.
      
      8) Don't dump autogenerated seed in nft_hash to userspace, this is
         very confusing to the user, again from Liping.
      
      9) Fix wrong conntrack netns module refcount in ipt_CLUSTERIP,
         from Gao feng.

      As a result many (all?) OMAP systems using omapfb will crash at boot.
      Fix by deleting the whole function.
