+Subject: sctp: Do not reset the packet during sctp_packet_config().
+
+From: Vlad Yasevich <vladislav.yasevich@hp.com>
+
+commit 4bdab43323b459900578b200a4b8cf9713ac8fab upstream.
+
+sctp_packet_config() is called when getting the packet ready
+for appending of chunks.  The function should not touch the
+current state, since it's possible to ping-pong between two
+transports when sending, and that can result packet corruption
+followed by skb overlfow crash.
