[PATCH 0/2] lib/crypto: Use size_t lengths for Poly1305 and ChaCha

[Eric Biggers]

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.
