If anyone has any objections, please let us know. ------------------ From: Trond Myklebust commit 246408dcd5dfeef2df437ccb0ef4d6ee87805f58 upstream. If we call xs_close(), we're in one of two situations: - Autoclose, which means we don't expect to resend a request - bind+connect failed, which probably means the port is in use Signed-off-by: Trond Myklebust Signed-off-by: Greg Kroah-Hartman --- net/sunrpc/xprtsock.c | 2 ++ 1 file changed, 2 insertions(+) --- a/net/sunrpc/xprtsock.c +++ b/net/sunrpc/xprtsock.c @@ -710,6 +710,8 @@ static void xs_reset_transport(struct so if (sk == NULL) return; + transport->srcport = 0; + write_lock_bh(&sk->sk_callback_lock); transport->inet = NULL; transport->sock = NULL;
