When copying in a struct msghdr from the user, if the user has set the msg_namelen parameter to a negative value it gets clamped to a valid size due to a comparison between signed and unsigned values. Ensure the syscall errors when the user passes in a negative value. ...
If we have cmsg attached AND we transferred partial data at least, clear msg_controllen on retry so we don't attempt to send that again. Cc: stable@vger.kernel.org # 5.10+ Fixes: cac9e44 ("io_uring/net: save msghdr->msg_control for retries") Reported-by: Stefan Metzmacher <metze...
