Subject: [PATCH 0/5] lib/crypto: Poly1305 fixes
Date: Sun, 6 Jul 2025 16:10:55 -0700 [thread overview]
Message-ID: <20250706231100.176113-1-ebiggers@kernel.org> (raw)
This series is also available at:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git poly1305-fixes
This series fixes the arm, arm64, and x86 Poly1305 functions to not
corrupt random tasks' registers when called in the "wrong" context. It
also fixes a performance regression on x86 with short messages.
This series is needed for my upcoming poly1305_kunit test to pass.
