dm: fix potential for q->make_request_fn NULL pointer (2020-01-27 14:52:36 -0500)
Please pull, thanks!
Mike
----------------------------------------------------------------
- Fix DM core's potential for q->make_request_fn NULL pointer in the
unlikely case that a DM device is created without a DM table and
then accessed due to upper-layer userspace code or user error.
- Fix DM thin-provisioning's metadata_pre_commit_callback to not use
memory after it is free'd. Also refactor code to disallow changing
the thin-pool's data device once in use -- doing so guarantees smae
lifetime of pool's data device relative to the pool metadata.
- Fix DM space maps used by DM thinp and DM cache to avoid reuse of a
already used block. This race was identified with extremely heavy
snapshot use in the context of DM thin provisioning.
- Fix DM raid's table status relative to an active rebuild.
- Fix DM crypt to use GFP_NOIO rather than GFP_NOFS in call to
skcipher_request_alloc(). Also fix benbi IV constructor crash if
used in authenticated mode.
- Add DM crypt support for Elephant diffuser to allow for Bitlocker
compatibility.
- Fix DM verity target to not prefetch hash blocks for data that has
already been verified.
- Fix DM writecache's incorrect flush sequence during commit when in
SSD mode.
- Improve DM writecache's sequential write performance on SSDs.
- Add DM zoned target support for zone sizes smaller than 128MiB.
- Add DM multipath 'queue_if_no_path_timeout_secs' module param to
allow timeout if path isn't reinstated. This allows users a kernel
safety-net against IO hanging indefinitely, due to no active paths,
that has historically only been provided by multipathd userspace.
- Various DM code cleanups to use true/false rather than 1/0, a
variable rename in dm-dust, and fix for a math error in comment for
DM thin metadata's ondisk format.
