Subject: [PATCH] bpf, x32: Fix bug with ALU64 {LSH, RSH, ARSH} BPF_X shift by 0
Date: Thu, 21 Nov 2019 15:45:11 +0800	[thread overview]
Message-ID: <20191121074511.GC15326@udknight> (raw)

commit 68a8357ec15bdce55266e9fba8b8b3b8143fa7d2 upstream.

The fix only affects x32 bpf jit, and it is critical to use x32 bpf jit on a
unpatched system, so I think we should backport it to the only affected stable
kernel version: v4.19

Thanks.
