Subject: [PATCH 0/2] thunderbolt: HMAC fix and cleanup
Date: Thu, 31 Jul 2025 12:25:43 -0700	[thread overview]
Message-ID: <20250731192545.29869-1-ebiggers@kernel.org> (raw)

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

Patch 2 simplifies the HMAC computation in the thunderbolt driver by
using the library API instead of crypto_shash.  Note that this depends
on the HMAC-SHA256 library API that was merged for v6.17-rc1.

Eric Biggers (2):
  thunderbolt: Compare HMAC values in constant time
  thunderbolt: Use HMAC-SHA256 library instead of crypto_shash
