From: William Kucharski <william.kucharski@oracle.com> stable inclusion from stable-v5.10.84 commit e226180acc49cf78fa1502b5b7e7f1b7ebc017c1 bugzilla: 186030 https://gitee.com/openeuler/kernel/issues/I4QV2F Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 19f36edf14bcdb783aef3af8217df96f76a8ce34 upstream. Correct an error where setting /proc/sys/net/rds/tcp/rds_tcp_rcvbuf would instead modify the socket's sk_sndbuf and would leave sk_rcvbuf untouched.
