[PATCH 0/2] tpm: HMAC fix and cleanup

[Eric Biggers <ebiggers@kernel.org>]

Patch 1 fixes the HMAC comparison in the tpm driver to be constant-time.

Patch 2 simplifies the HMAC computation in the tpm driver by using the
library API instead of an open-coded HMAC implementation.  Note that
this depends on the HMAC library API that was merged for v6.17-rc1.

Eric Biggers (2):
  tpm: Compare HMAC values in constant time
  tpm: Use HMAC-SHA256 library instead of open-coded HMAC
