From d54072587146dd0db9bb52b513234d944edabda3 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Tue, 2 Mar 2021 09:24:45 +0100 Subject: kernel-5.4: backport fd16931a2f51 for chacha neon MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Without this patch, the chacha block counter is not incremented on neon rounds, resulting in incorrect calculations and corrupt packets. This also switches to using `--no-numbered --zero-commit` so that future diffs are smaller.
