Donenfeld <Jason@zx2c4.com> # Date: Wed Mar 18 20:27:32 2020 -0600 # # crypto: arm64/chacha - correctly walk through blocks # # Prior, passing in chunks of 2, 3, or 4, followed by any additional # chunks would result in the chacha state counter getting out of sync, # resulting in incorrect encryption/decryption, which is a pretty nasty # crypto vuln: "why do images look weird on webpages?" WireGuard users # never experienced this prior, because we have always, out of tree, used # a different crypto library, until the recent Frankenzinc addition. This # commit fixes the issue by advancing the pointers and state counter by # the actual size processed. It also fixes up a bug in the (optional, # costly) stride test that prevented it from running on arm64. # # Fixes: b3aad5bad26a ("crypto: arm64/chacha - expose arm64 ChaCha routine as library function") # Reported-and-tested-by: Emil Renner Berthing <kernel@esmil.dk> # Cc: Ard Biesheuvel <ardb@kernel.org> # Cc: stable@vger.kernel.org # v5.5+ # Signed-off-by: Jason A.
