[PATCH 0/3] KEYS: trusted_tpm1: HMAC fix and cleanup

Posted by Eric Biggers 2 months ago

Patch 1 fixes the HMAC-SHA1 comparison in trusted_tpm1 to be
constant-time.

Patch 2 simplifies the SHA-1 and HMAC-SHA1 computation in trusted_tpm1
by using library APIs instead of crypto_shash.  Note that this depends
on the SHA-1 and HMAC-SHA1 library APIs that were merged for v6.17-rc1.

Patch 3 is a trusted_tpm1 cleanup that moves private functionality out
of a public header.
