Merge tag 'for-6.5/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

- Update DM crypt to allocate compound pages if possible

- Fix DM crypt target's crypt_ctr_cipher_new return value on invalid
AEAD cipher

- Fix DM flakey testing target's write bio corruption feature to
corrupt the data of a cloned bio instead of the original

- Add random_read_corrupt and random_write_corrupt features to DM
flakey target

- Fix ABBA deadlock in DM thin metadata by resetting associated bufio
client rather than destroying and recreating it

- A couple other small DM thinp cleanups

- Update DM core to support disabling block core IO stats accounting
and optimize away code that isn't needed if stats are disabled

- Other small DM core cleanups

- Improve DM integrity target to not require so much memory on 32 bit
systems. Also only allocate the recalculate buffer as needed (and
increasingly reduce its size on allocation failure)

- Update DM integrity to use %*ph for printing hexdump of a small
buffer. Also update DM integrity documentation

- Various DM core ioctl interface hardening. Now more careful about
alignment of structures and processing of input passed to the kernel
from userspace.

Also disallow the creation of DM devices named "control", "." or ".."

- Eliminate GFP_NOIO workarounds for __vmalloc and kvmalloc in DM
core's ioctl and bufio code

dm flakey: clone pages on write bio before corrupting them

dm-flakey has an option to corrupt write bios. It corrupts the memory that
is being written. This can cause system crashes or security bugs - for
example, if the user writes a shared library code with O_DIRECT flag to a
dm-flakey device, it corrupts the memory for all users that have the
shared library mapped.

Fix this bug by cloning the bio and corrupting the clone rather than
the original.

Also drop the test for ZERO_PAGE(0) - it can't happen because we write
the cloned pages.

Merge tag 'for-6.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

- Split dm-bufio's rw_semaphore and rbtree. Offers improvements to
dm-bufio's locking to allow increased concurrent IO -- particularly
for read access for buffers already in dm-bufio's cache.

- Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim
at improving concurrent IO (for the DM thinp target).

- Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks
and rbtrees used are managed by dm_num_hash_locks(). And the hash
function used by both is dm_hash_locks_index().

- Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to
be split at the target specified boundary (in terms of
max_discard_sectors, max_write_zeroes_sectors and
max_secure_erase_sectors respectively).

- DM verity error handling fix for check_at_most_once on FEC.

- Update DM verity target to emit audit events on verification failure
and more.

- DM core ->io_hints improvements needed in support of new discard
support that is added to the DM "zero" and "error" targets.

- Fix missing kmem_cache_destroy() call in initialization error path of
both the DM integrity and DM clone targets.

- A couple fixes for DM flakey, also add "error_reads" feature.

- Fix DM core's resume to not lock FS when the DM map is NULL;
otherwise initial table load can race with FS mount that takes
superblock's ->s_umount rw_semaphore.

- Various small improvements to both DM core and DM targets.
