The commit f00432063db1a0db484e85193eccc6845435b80e upstream (SUNRPC: Ensure we flush any closed sockets before xs_xprt_free()) fixes CVE-2022-28893, hence good candidate for stable trees. The above commit depends on 3be232f(SUNRPC: Prevent immediate close+reconnect) and 89f4249(SUNRPC: Don't call connect() more than once on a TCP socket). Commit 3be232f depends on commit e26d9972720e(SUNRPC: Clean up scheduling of autoclose). Commits e26d9972720e, 3be232f, f00432063db1 apply cleanly on 5.10 kernel. commit 89f4249 didn't apply cleanly. This patch series includes all the commits required for back porting f00432063db1.
