From: Erik Hugne <[email protected]> Fix regression bug introduced in commit 365ad353c256 ("tipc: reduce risk of user starvation during link congestion")
Only signal -EDESTADDRREQ for RDM/DGRAM if we don't have a cached sockaddr. Signed-off-by: Erik Hugne <[email protected]> --- Jon/Ying, i have a very limited test setup, i hope you can review and ensure that the proposed change is safe. I have tested it (on net-next) that it at least solves the problem i had. Once the fix is mainline, i will submit patches to bash for shell network redirection. This should be in net, because it's a bug that breaks connectionless messaging in many ways. Feel free to forward it there after your review/signoff. net/tipc/socket.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/tipc/socket.c b/net/tipc/socket.c index e482b342bfa8..3274ef625dba 100644 --- a/net/tipc/socket.c +++ b/net/tipc/socket.c @@ -1333,7 +1333,7 @@ static int __tipc_sendmsg(struct socket *sock, struct msghdr *m, size_t dlen) if (unlikely(!dest)) { dest = &tsk->peer; - if (!syn || dest->family != AF_TIPC) + if (!syn && dest->family != AF_TIPC) return -EDESTADDRREQ; } -- 2.14.1 _______________________________________________ tipc-discussion mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/tipc-discussion
