Hi Linus, The following changes since commit c79f46a282390e0f5b306007bf7b11a46d529538: Linux 5.5-rc5 (2020-01-05 14:23:27 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/for-5.6/dm-changes for you to fetch changes up to 47ace7e012b9f7ad71d43ac9063d335ea3d6820b: 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. ---------------------------------------------------------------- Anatol Pomazau (1): dm mpath: Add timeout mechanism for queue_if_no_path Bryan Gurney (1): dm dust: change ret to r in dust_map_write Dmitry Fomichev (1): dm zoned: support zone sizes smaller than 128MiB Heinz Mauelshagen (1): dm raid: table line rebuild status fixes Jeffle Xu (1): dm thin metadata: Fix trivial math error in on-disk format documentation Joe Thornber (1): dm space map common: fix to ensure new block isn't already in use Mike Snitzer (3): dm thin metadata: use pool locking at end of dm_pool_metadata_close dm thin: fix use-after-free in metadata_pre_commit_callback dm: fix potential for q->make_request_fn NULL pointer Mikulas Patocka (5): dm crypt: fix GFP flags passed to skcipher_request_alloc() dm writecache: fix incorrect flush sequence when doing SSD mode commit dm thin: don't allow changing data device during thin-pool reload dm thin: change data device's flush_bio to be member of struct pool dm writecache: improve performance of large linear writes on SSDs Milan Broz (2): dm crypt: Implement Elephant diffuser for Bitlocker compatibility dm crypt: fix benbi IV constructor crash if used in authenticated mode xianrong.zhou (1): dm verity: don't prefetch hash blocks for already-verified data zhengbin (4): dm mpath: use true/false for bool variable dm bio prison v2: use true/false for bool variable dm snapshot: use true/false for bool variable dm thin metadata: use true/false for bool variable .../admin-guide/device-mapper/dm-raid.rst | 2 + drivers/md/dm-bio-prison-v2.c | 2 +- drivers/md/dm-crypt.c | 335 ++++++++++++++++++++- drivers/md/dm-dust.c | 6 +- drivers/md/dm-mpath.c | 68 ++++- drivers/md/dm-raid.c | 43 +-- drivers/md/dm-snap.c | 6 +- drivers/md/dm-thin-metadata.c | 22 +- drivers/md/dm-thin.c | 36 ++- drivers/md/dm-verity-target.c | 18 +- drivers/md/dm-writecache.c | 71 +++-- drivers/md/dm-zoned-metadata.c | 23 +- drivers/md/dm.c | 9 +- drivers/md/persistent-data/dm-space-map-common.c | 27 ++ drivers/md/persistent-data/dm-space-map-common.h | 2 + drivers/md/persistent-data/dm-space-map-disk.c | 6 +- drivers/md/persistent-data/dm-space-map-metadata.c | 5 +- 17 files changed, 580 insertions(+), 101 deletions(-)
