Subject: [PATCH 0/2] lib/crypto: Use size_t lengths for Poly1305 and ChaCha
Date: Wed, 14 Oct 2026 17:26:02 +0200 [thread overview]
Message-ID: <20261014152604.323310-1-ebiggers@kernel.org> (raw)
This series upgrades the Poly1305 and ChaCha functions to use size_t
lengths, matching the rest of the crypto library.
It also fixes the (not currently reached) handling of lengths above
S32_MAX bytes, and (not currently known to matter in practice) the
assembly functions depending on unspecified high register bits.
This more comprehensively addresses the issues identified in
https://lore.kernel.org/r/20261012-libcrypto-4gib-lengths-v1-0-ea566c129a2e@genproof.com
This series is targeting libcrypto-next.
