When loading a device-mapper table for a request-based mapped device, and the allocation/initialization of the blk_mq_tag_set for the device fails, a following device remove will cause a double free.

If fast table reloads occur during an ongoing reshape of raid4/5/6 devices the target may race reading a superblock vs the the MD resync thread; causing an inconclusive reshape state to be read in its constructor. lvm2 test lvconvert-raid-reshape-stripes-load-reload.sh can cause BUG_ON() to trigger in md_run(), e.g.: "kernel BUG at drivers/md/raid5.c:7567!". Scenario triggering the bug: 1. the MD sync thread calls end_reshape() from raid5_sync_request() when done reshaping. However end_reshape() _only_ updates the reshape position to MaxSector keeping the changed layout configuration though (i.e. any delta disks, chunk sector or RAID algorithm changes). That inconclusive configuration is stored in the superblock. 2. dm-raid constructs a mapping, loading named inconsistent superblock as of step 1 before step 3 is able to finish resetting the reshape state completely, and calls md_run() which leads to mentioned bug in raid5.c. 3. the MD RAID personality's finish_reshape() is called; which resets the reshape information on chunk sectors, delta disks, etc. This explains why the bug is rarely seen on multi-core machines, as MD's finish_reshape() superblock update races with the dm-raid constructor's superblock load in step 2. Fix identifies inconclusive superblock content in the dm-raid constructor and resets it before calling md_run(), factoring out identifying checks into rs_is_layout_change() to share in existing rs_reshape_requested() and new rs_reset_inclonclusive_reshape(). Also enhance a comment and remove an empty line. Cc: stable@vger.kernel.org Signed-off-by:

When LVM needs to find a device with a particular UUID it needs to ask for UUID for each device. This patch returns UUID directly in the list of devices, so that LVM doesn't have to query all the devices with an ioctl. The UUID is returned if the flag DM_UUID_FLAG is set in the parameters. Returning UUID is done in backward-compatible way. There's one unused 32-bit word value after the event number. This patch sets the bit DM_NAME_LIST_FLAG_HAS_UUID if UUID is present and DM_NAME_LIST_FLAG_DOESNT_HAVE_UUID if it isn't (if none of these bits is set, then we have an old kernel that doesn't support returning UUIDs). The UUID is stored after this word. The 'next' value is updated to point after the UUID, so that old version of libdevmapper will skip the UUID without attempting to interpret it. Signed-off-by:

When a DM device is first created it doesn't yet have an established capacity, therefore the use of set_capacity_and_notify() should be conditional given the potential for needless pr_info "detected capacity change" noise even if capacity is 0.

Commit 24f6b603 ("dm table: fix zoned iterate_devices based device capability checks") triggered dm table load failure when dm-zoned device is set up for zoned block devices and a regular device for cache. The commit inverted logic of two callback functions for iterate_devices: device_is_zoned_model() and device_matches_zone_sectors(). The logic of device_is_zoned_model() was inverted then all destination devices of all targets in dm table are required to have the expected zoned model. This is fine for dm-linear, dm-flakey and dm-crypt on zoned block devices since each target has only one destination device. However, this results in failure for dm-zoned with regular cache device since that target has both regular block device and zoned block devices. As for device_matches_zone_sectors(), the commit inverted the logic to require all zoned block devices in each target have the specified zone_sectors. This check also fails for regular block device which does not have zones. To avoid the check failures, fix the zone model check and the zone sectors check. For zone model check, introduce the new feature flag DM_TARGET_MIXED_ZONED_MODEL, and set it to dm-zoned target. When the target has this flag, allow it to have destination devices with any zoned model. For zone sectors check, skip the check if the destination device is not a zoned block device. Also add comments and improve an error message to clarify expectations to the two checks. Fixes: 24f6b603 ("dm table: fix zoned iterate_devices based device capability checks") Signed-off-by:
