mckusick [Fri, 22 Sep 2017 12:45:15 +0000 (12:45 +0000)]
Continuing efforts to provide hardening of FFS, this change adds a
check hash to cylinder groups. If a check hash fails when a cylinder
group is read, no further allocations are attempted in that cylinder
group until it has been fixed by fsck. This avoids a class of
filesystem panics related to corrupted cylinder group maps. The
hash is done using crc32c.

Check hases are added only to UFS2 and not to UFS1 as UFS1 is primarily
used in embedded systems with small memories and low-powered processors
which need as light-weight a filesystem as possible.

Specifics of the changes:

sys/sys/buf.h:
    Add BX_FSPRIV to reserve a set of eight b_xflags that may be used
    by individual filesystems for their own purpose. Their specific
    definitions are found in the header files for each filesystem
    that uses them. Also add fields to struct buf as noted below.

sys/kern/vfs_bio.c:
    It is only necessary to compute a check hash for a cylinder
    group when it is actually read from disk. When calling bread,
    you do not know whether the buffer was found in the cache or
    read. So a new flag (GB_CKHASH) and a pointer to a function to
    perform the hash has been added to breadn_flags to say that the
    function should be called to calculate a hash if the data has
    been read. The check hash is placed in b_ckhash and the B_CKHASH
    flag is set to indicate that a read was done and a check hash
    calculated. Though a rather elaborate mechanism, it should
    also work for check hashing other metadata in the future. A
    kernel internal API change was to change breada into a static
    fucntion and add flags and a function pointer to a check-hash
    function.

sys/ufs/ffs/fs.h:
    Add flags for types of check hashes; stored in a new word in the
    superblock. Define corresponding BX_ flags for the different types
    of check hashes. Add a check hash word in the cylinder group.

sys/ufs/ffs/ffs_alloc.c:
    In ffs_getcg do the dance with breadn_flags to get a check hash and
    if one is provided, check it.

sys/ufs/ffs/ffs_vfsops.c:
    Copy across the BX_FFSTYPES flags in background writes.
    Update the check hash when writing out buffers that need them.

sys/ufs/ffs/ffs_snapshot.c:
    Recompute check hash when updating snapshot cylinder groups.

sys/libkern/crc32.c:
lib/libufs/Makefile:
lib/libufs/libufs.h:
lib/libufs/cgroup.c:
    Include libkern/crc32.c in libufs and use it to compute check
    hashes when updating cylinder groups.

Four utilities are affected:

sbin/newfs/mkfs.c:
    Add the check hashes when building the cylinder groups.

sbin/fsck_ffs/fsck.h:
sbin/fsck_ffs/fsutil.c:
    Verify and update check hashes when checking and writing cylinder groups.

sbin/fsck_ffs/pass5.c:
    Offer to add check hashes to existing filesystems.
    Precompute check hashes when rebuilding cylinder group
    (although this will be done when it is written in fsutil.c
    it is necessary to do it early before comparing with the old
    cylinder group)

sbin/dumpfs/dumpfs.c
    Print out the new check hash flag(s)

sbin/fsdb/Makefile:
    Needs to add libufs now used by pass5.c imported from fsck_ffs.

  commit into illumos:

  commit f763c3d1df569a8d6b60bcb5e95cf07aa7a189e6
  Author: LOLi <loli10K@users.noreply.github.com>
  Date:   Mon Aug 21 17:59:48 2017 +0200

      Fix range locking in ZIL commit codepath

      Since OpenZFS 7578 (1b7c1e5) if we have a ZVOL with logbias=throughput
      we will force WR_INDIRECT itxs in zvol_log_write() setting itx->itx_lr
      offset and length to the offset and length of the BIO from
      zvol_write()->zvol_log_write(): these offset and length are later used
      to take a range lock in zillog->zl_get_data function: zvol_get_data().

      Now suppose we have a ZVOL with blocksize=8K and push 4K writes to
      offset 0: we will only be range-locking 0-4096. This means the
      ASSERTion we make in dbuf_unoverride() is no longer valid because now
      dmu_sync() is called from zilog's get_data functions holding a partial
      lock on the dbuf.

      Fix this by taking a range lock on the whole block in zvol_get_data().

Previously callout_reset() was called with a "ticks" value that was

frequently: On systems with hz=1000 a quanta value of 200 resulted in
~250 calls and a value of 100 in ~111 calls.

For the "queue_depth" and "bandwidth" limiters the difference doesn't
matter but the "iops" limiter depends on the scheduling to enforce the
correct maximum.

MFV r323789:  8473 scrub does not detect errors on active spares

https://www.illumos.org/issues/8473
Scrubbing is supposed to detect and repair all errors in the pool. However,
it wrongly ignores active spare devices. The problem can easily be
reproduced in OpenZFS at git rev 0ef125d with these commands:

truncate -s 64m /tmp/a /tmp/b /tmp/c
sudo zpool create testpool mirror /tmp/a /tmp/b spare /tmp/c
sudo zpool replace testpool /tmp/a /tmp/c
/bin/dd if=/dev/zero bs=1024k count=63 oseek=1 conv=notrunc of=/tmp/c
sync
sudo zpool scrub testpool
zpool status testpool # Will show 0 errors, which is wrong
sudo zpool offline testpool /tmp/a
sudo zpool scrub testpool
zpool status testpool # Will show errors on /tmp/c,
      # which should've already been fixed

FreeBSD head is partially affected: the first scrub will detect some errors, but the second scrub will detect more.
