       "Here are some patches for 4.18 to fix regressions, accounting
        problems, overflow problems, and to strengthen metadata validation to
        prevent corruption.
      
        This series has been run through a full xfstests run over the weekend
        and through a quick xfstests run against this morning's master, with
        no major failures reported.
      
        Changes since last update:
      
         - more metadata validation strengthening to prevent crashes.
      
         - fix extent offset overflow problem when insert_range on a 512b
           block fs
      
         - fix some off-by-one errors in the realtime fsmap code
      
         - fix some math errors in the default resblks calculation when free
           space is low
      
         - fix a problem where stale page contents are exposed via mmap read
           after a zero_range at eof

      checkpatch: remove warning for 'old' stable@kernel.org address · 3b41c3e2
      Linus Torvalds authored
      It may not be the actual real stable mailing list address, but the
      stable scripts to actually pick up on the traditional way to mark stable
      patches.
      
      There are also reasons to explicitly avoid using the actual mailing list
      address, since security patches with embargo dates generally do want the
      stable marking, but don't want tools etc to mistakenly send the patch
      out to the mailing list early.
      
      So don't warn for things that are still actively used and explicitly
      supported.

      X.509: unpack RSA signatureValue field from BIT STRING · b65c32ec
      Maciej S. Szmigiero authored
      The signatureValue field of a X.509 certificate is encoded as a BIT STRING.
      For RSA signatures this BIT STRING is of so-called primitive subtype, which
      contains a u8 prefix indicating a count of unused bits in the encoding.
      
      We have to strip this prefix from signature data, just as we already do for
      key data in x509_extract_key_data() function.
      
      This wasn't noticed earlier because this prefix byte is zero for RSA key
      sizes divisible by 8. Since BIT STRING is a big-endian encoding adding zero
      prefixes has no bearing on its value.
      
      The signature length, however was incorrect, which is a problem for RSA
      implementations that need it to be exactly correct (like AMD CCP).

      xfs: fix fdblocks accounting w/ RMAPBT per-AG reservation · d8cb5e42
      Darrick J. Wong authored
      In __xfs_ag_resv_init we incorrectly calculate the amount by which to
      decrease fdblocks when reserving blocks for the rmapbt.  Because rmapbt
      allocations do not decrease fdblocks, we must decrease fdblocks by the
      entire size of the requested reservation in order to achieve our goal of
      always having enough free blocks to satisfy an rmapbt expansion.
      
      This is in contrast to the refcountbt/finobt, which /do/ subtract from
      fdblocks whenever they allocate a block.  For this allocation type we
      preserve the existing behavior where we decrease fdblocks only by the
      requested reservation minus the size of the existing tree.
      
      This fixes the problem where the available block counts reported by
      statfs change across a remount if there had been an rmapbt size change
      since mount time.

      xfs: ensure post-EOF zeroing happens after zeroing part of a file · e53c4b59
      Darrick J. Wong authored
      If a user asks us to zero_range part of a file, the end of the range is
      EOF, and not aligned to a page boundary, invoke writeback of the EOF
      page to ensure that the post-EOF part of the page is zeroed.  This
      ensures that we don't expose stale memory contents via mmap, if in a
      clumsy manner.
      
      Found by running generic/127 when it runs zero_range and mapread at EOF
      one after the other.

      xfs: fix off-by-one error in xfs_rtalloc_query_range · a3a374bf
      Darrick J. Wong authored
      In commit 8ad560d2 ("xfs: strengthen rtalloc query range checks")
      we strengthened the input parameter checks in the rtbitmap range query
      function, but introduced an off-by-one error in the process.  The call
      to xfs_rtfind_forw deals with the high key being rextents, but we clamp
      the high key to rextents - 1.  This causes the returned results to stop
      one block short of the end of the rtdev, which is incorrect.

      xfs: fix uninitialized field in rtbitmap fsmap backend · 232d0a24
      Darrick J. Wong authored
      Initialize the extent count field of the high key so that when we use
      the high key to synthesize an 'unknown owner' record (i.e. used space
      record) at the end of the queried range we have a field with which to
      compute rm_blockcount.  This is not strictly necessary because the
      synthesizer never uses the rm_blockcount field, but we can shut up the
      static code analysis anyway.

      xfs: recheck reflink state after grabbing ILOCK_SHARED for a write · 5bd88d15
      Darrick J. Wong authored
      The reflink iflag could have changed since the earlier unlocked check,
      so if we got ILOCK_SHARED for a write and but we're now a reflink inode
      we have to switch to ILOCK_EXCL and relock.

      xfs: don't allow insert-range to shift extents past the maximum offset · f62cb48e
      Darrick J. Wong authored
      Zorro Lang reports that generic/485 blows an assert on a filesystem with
      512 byte blocks.  The test tries to fallocate a post-eof extent at the
      maximum file size and calls insert range to shift the extents right by
      two blocks.  On a 512b block filesystem this causes startoff to overflow
      the 54-bit startoff field, leading to the assert.
      
      Therefore, always check the rightmost extent to see if it would overflow
      prior to invoking the insert range machinery.

      xfs: don't trip over negative free space in xfs_reserve_blocks · aafe12ce
      Darrick J. Wong authored
      If we somehow end up with a filesystem that has fewer free blocks than
      the blocks set aside to avoid ENOSPC deadlocks, it's possible that the
      free space calculation in xfs_reserve_blocks will spit out a negative
      number (because percpu_counter_sum returns s64).  We fail to notice
      this negative number and set fdblks_delta to it.  Now we increment
      fdblocks(!) and the unsigned type of m_resblks means that we end up
      setting a ridiculously huge m_resblks reservation.
      
      Avoid this comedy of errors by detecting the negative free space and
      returning -ENOSPC.

      xfs: allow empty transactions while frozen · 10ee2526
      Darrick J. Wong authored
      In commit e89c0413 ("xfs: implement the GETFSMAP ioctl") we
      created the ability to obtain empty transactions.  These transactions
      have no log or block reservations and therefore can't modify anything.
      Since they're also NO_WRITECOUNT they can run while the fs is frozen,
      so we don't need to WARN_ON about that usage.

      MIPS: Add ksig argument to rseq_{signal_deliver,handle_notify_resume} · 662d855c
      Paul Burton authored
      Commit 784e0300 ("rseq: Avoid infinite recursion when delivering
      SIGSEGV") added a new ksig argument to the rseq_signal_deliver() &
      rseq_handle_notify_resume() functions, and was merged in v4.18-rc2.
      Meanwhile MIPS support for restartable sequences was also merged in
      v4.18-rc2 with commit 9ea141ad ("MIPS: Add support for restartable
      sequences"), and therefore didn't get updated for the API change.
      
      This results in build failures like the following:
      
          CC      arch/mips/kernel/signal.o
        arch/mips/kernel/signal.c: In function 'handle_signal':
        arch/mips/kernel/signal.c:804:22: error: passing argument 1 of
          'rseq_signal_deliver' from incompatible pointer type
          [-Werror=incompatible-pointer-types]
          rseq_signal_deliver(regs);
                              ^~~~
        In file included from ./include/linux/context_tracking.h:5,
                         from arch/mips/kernel/signal.c:12:
        ./include/linux/sched.h:1811:56: note: expected 'struct ksignal *' but
          argument is of type 'struct pt_regs *'
          static inline void rseq_signal_deliver(struct ksignal *ksig,
                                                 ~~~~~~~~~~~~~~~~^~~~

          'rseq_signal_deliver'
          rseq_signal_deliver(regs);
          ^~~~~~~~~~~~~~~~~~~
      
      Fix this by adding the ksig argument as was done for other architectures
      in commit 784e0300 ("rseq: Avoid infinite recursion when delivering
      SIGSEGV").

      The function efx_rps_hash_bucket is local to the source and
      does not need to be in global scope, so make it static.
      
      Cleans up sparse warning:
      symbol 'efx_rps_hash_bucket' was not declared. Should it be static?

        perf stat:
      
         - Fix metric column header display alignment
      
         - Improve error messages for default attributes, providing better
           output for error in command line.
      
         - Add --interval-clear option, to provide a 'watch' like printing

         - Do not blindly assume that 'struct perf_evsel' can be obtained via
           a straight forward container_of() as there are call sites which
           hand in a plain 'struct hist' which is not part of a container.

           point to the problematic token"
