The commit f00432063db1a0db484e85193eccc6845435b80e (SUNRPC: Ensure we flush any closed sockets before xs_xprt_free()) upstream fixes CVE-2022-28893, hence good candidate for stable trees. The above commit depends on 3be232f11a3c (SUNRPC: Prevent immediate close+reconnect) and 89f42494f92f (SUNRPC: Don't call connect() more than once on a TCP socket). Commit 3be232f11a3c depends on commit e26d9972720e (SUNRPC: Clean up scheduling of autoclose).
Commits e26d9972720e, 3be232f11a3c apply cleanly on 5.4 kernel. commit 89f42494f92f and f00432063db1 didn't apply cleanly. This patch series includes all the commits required for back porting f00432063db1.
