rds: MP-RDS may use an invalid c_path ...
[ Upstream commit a43cced9a348901f9015f4730b70b69e7c41a9c9 ]
rds_sendmsg() calls rds_send_mprds_hash() to find a c_path to use to
send a message. Suppose the RDS connection is not yet up. In
rds_send_mprds_hash(), it does
if (conn->c_npaths == 0)
wait_event_interruptible(conn->c_hs_waitq,
(conn->c_npaths != 0));
If it is interrupted before the connection is set up,
rds_send_mprds_hash() will return a non-zero hash value. Hence
rds_sendmsg() will use a non-zero c_path to send the message. But if
the RDS connection ends up to be non-MP capable, the message will be
lost as only the zero c_path can be used.
