Depends what you mean by "upstream".  do_udp_sendmsg net/rxrpc/output.c:27
should only be in net-next/master outside of my tree; it shouldn't be in
Linus's tree yet.

Was the crash fixed by either of:

66f6fd278c67 (tag: rxrpc-next-20221116) rxrpc: Fix network address validation
6423ac2eb31e rxrpc: Fix oops from calling udpv6_sendmsg() on AF_INET socket
