    Subject[78/80] sctp: Do not reset the packet during sctp_packet_config().
    2.6.35-stable review patch.  If anyone has any objections, please let us know.


    From: Vlad Yasevich <>

    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.
