move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

nvme-auth: use crypto_shash_tfm_digest()

2023-11-06T16:05:53Z

Simplify nvme_auth_augmented_challenge() by using crypto_shash_tfm_digest() instead of an alloc+init+update+final sequence. This should also improve performance. Signed-off-by: Eric Biggers Reviewed-by: Christoph Hellwig Signed-off-by: Keith Busch

nvme-auth: allow mixing of secret and hash lengths

2023-10-17T20:57:55Z

We can now use any of the secret transformation hashes with a secret, regardless of the secret size. e.g. a 32 byte key with the SHA-512(64 byte) hash. The example secret from the spec should now be permitted with any of the following: DHHC-1:00:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n: DHHC-1:01:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n: DHHC-1:02:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n: DHHC-1:03:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n: Note: Secrets are still restricted to 32,48 or 64 bits.

nvme-auth: use transformed key size to create resp

2023-10-17T20:57:54Z

This does not change current behaviour as the driver currently verifies that the secret size is the same size as the length of the transformation hash. Co-developed-by: Akash Appaiah Signed-off-by: Akash Appaiah Signed-off-by: Mark O'Donovan Reviewed-by: Hannes Reinecke Signed-off-by: Keith Busch

treewide: use get_random_u32() when possible

2022-10-11T23:42:58Z

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.
