"There are fixes for some corner case crashes in dm-cache and
dm-mirror, new setup functionality for dm-vdo, and miscellaneous minor
fixes and cleanups, especially to dm-verity.

dm-vdo:
- Make dm-vdo able to format the device itself, like other dm
targets, instead of needing a userspace formating program
- Add some sanity checks and code cleanup

dm-cache:
- Fix crashes and hangs when operating in passthrough mode (which
have been around, unnoticed, since 4.12), as well as a late
arriving fix for an error path bug in the passthrough fix
- Fix a corner case memory leak

dm-verity:
- Another set of minor bugfixes and code cleanups to the forward
error correction code

dm-mirror
- Fix minor initialization bug
- Fix overflow crash on a large devices with small region sizes

dm-crypt: Reimplement elephant diffuser using AES library

Simplify and optimize dm-crypt's implementation of Bitlocker's "elephant
diffuser" to use the AES library instead of an "ecb(aes)"
crypto_skcipher.

Note: struct aes_enckey is fixed-size, so it could be embedded directly
in struct iv_elephant_private. But I kept it as a separate allocation
so that the size of struct crypt_config doesn't increase. The elephant
diffuser is rarely used in dm-crypt.

Make dm_ima_measure_on_table_load() use the SHA-256 library API instead
of crypto_shash to calculate the SHA-256 hash value that it needs. This
is simpler and more efficient. It also ensures that SHA-256 is actually
available and doesn't fail due to the unreliable loading by name.

While doing this, also use kasprintf() to simplify building the string
version of the digest.

dm-verity: allow REED_SOLOMON to be 'm' if DM_VERITY is 'm'

The dm-verity kconfig options make the common mistake of selecting a
dependency from a bool "sub-option" rather than the main tristate
option. This unnecessarily forces the dependency to built-in ('y').

Fix this by moving the selections of REED_SOLOMON and REED_SOLOMON_DEC8
into DM_VERITY, conditional on DM_VERITY_FEC.

This allows REED_SOLOMON to be 'm' if DM_VERITY is 'm'.

dm-verity: use SHA-256 library for SHA-256

When the hash algorithm is SHA-256 and the verity version is not 0, use
the SHA-256 library instead of crypto_shash.

This is a prerequisite for making dm-verity interleave the computation
of SHA-256 hashes for increased performance. That optimization is
available in the SHA-256 library but not in crypto_shash.

Even without interleaved hashing, switching to the library also slightly
improves performance by itself because it avoids the overhead of
crypto_shash, including indirect calls and other API overhead.
(Benchmark on x86_64, AMD Zen 5: hashing 4K blocks gets 2.1% faster.)

SHA-256 is by far the most common hash algorithm used with dm-verity.
It makes sense to optimize for the common case and fall back to the
generic crypto layer for uncommon cases, as suggested by Linus:

dm-crypt: Use MD5 library instead of crypto_shash

The lmk IV mode, which dm-crypt supports for Loop-AES compatibility,
involves an MD5 computation. Update its implementation to use the MD5
library API instead of crypto_shash. This has many benefits, such as:

- Simpler code. Notably, much of the error-handling code is no longer
needed, since the library functions can't fail.

- Reduced stack usage. crypt_iv_lmk_one() now allocates only 112 bytes
on the stack instead of 520 bytes.

- The library functions are strongly typed, preventing bugs like
https://lore.kernel.org/r/f1625ddc-e82e-4b77-80c2-dc8e45b54848@gmail.com

- Slightly improved performance, as the library provides direct access
to the MD5 code without unnecessary overhead such as indirect calls.

To preserve the existing behavior of lmk support being disabled when the
kernel is booted with "fips=1", make crypt_iv_lmk_ctr() check
fips_enabled itself. Previously it relied on crypto_alloc_shash("md5")
failing. (I don't know for sure that lmk *actually* needs to be
disallowed in FIPS mode; this just preserves the existing behavior.)
