Hi Linus, The following changes since commit 0bb80ecc33a8fb5a682236443c1e740d5c917d1d: Linux 6.6-rc1 (2023-09-10 16:28:41 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/for-6.6/dm-fixes for you to fetch changes up to a9ce385344f916cd1c36a33905e564f5581beae9: dm: don't attempt to queue IO under RCU protection (2023-09-15 15:39:59 -0400) Please pull, thanks. Mike ---------------------------------------------------------------- - Fix DM core retrieve_deps() UAF race due to missing locking of a DM table's list of devices that is managed using dm_{get,put}_device. - Revert DM core's half-baked RCU optimization if IO submitter has set REQ_NOWAIT. Can be revisited, and properly justified, after comprehensively auditing all of DM to also pass GFP_NOWAIT for any allocations if REQ_NOWAIT used. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmUEt7wACgkQxSPxCi2d A1prNwf/RB4EyKiSx7XS3ysM6mh/BPGO5FNjWwHebkrSFzAkEowo4i0cY9lRD0N4 x9Wbd5bcV8HarH/fiyffQxgdfXspAIrMt8z5hRnfElkBLzg6hHixxg/3sFCwg+U3 LG6AZFNLil7VmDeca9Pd8MCyXoy1u4ErWjkz3fU8pzzT+NDwRZPZhUMd/MFCWag6 q22S8KMXkYKiAHqKauF52CeDH77XsO66G70t/AElemZ66PpyKpasg2p99RCuHgTg 7jNuMTM6qXYWSWw8OswVXCPZEVfCp4zTFv1ebu9bagfDKR4ppNxwzyz7/CMkir14 4uKKzQ/cy8QND6OR/05zKh4U3ctqyA== =rVpu -----END PGP SIGNATURE----- ---------------------------------------------------------------- Jens Axboe (1): dm: don't attempt to queue IO under RCU protection Mikulas Patocka (1): dm: fix a race condition in retrieve_deps drivers/md/dm-core.h | 1 + drivers/md/dm-ioctl.c | 7 ++++++- drivers/md/dm-table.c | 32 ++++++++++++++++++++++++-------- drivers/md/dm.c | 23 ++--------------------- 4 files changed, 33 insertions(+), 30 deletions(-)
