From c2099fa61664e8fe8844cccdb7d1d18a5f0f94d1 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 22 Nov 2025 11:42:04 -0800 Subject: [PATCH] lib/crypto: poly1305: Add at_least decoration to fixed-size array params Add the at_least (i.e. 'static') decoration to the fixed-size array parameters of the poly1305 library functions. This causes clang to warn when a too-small array of known size is passed. Acked-by: Ard Biesheuvel Acked-by: "Jason A.
