Subject: [PATCH bpf 0/2] bpf: use 32bit safe version of u64_stats
Date: Tue, 26 Oct 2021 13:38:23 -0700 [thread overview]
Message-ID: <20211026203825.2720459-1-eric.dumazet@gmail.com> (raw)
From: Eric Dumazet <edumazet@google.com>
Two patches, fixing bugs added in 5.1 and 5.5
I have a followup patch for bpf-next, replacing the u64 fields
in struct bpf_prog_stats with u64_stats_t ones to avoid
possible sampling errors.

bpf: avoid races in __bpf_prog_run() for 32bit arches
bpf: fixes possible race in update_prog_stats() for 32bit arches
