    [IrDA]: Correctly handling socket error · bfb6709d
    Olaf Kirch authored
    This patch fixes an oops first reported in mid 2006 - see
     The cause of this bug report is that
    when an error is signalled on the socket, irda_recvmsg_stream returns
    without removing a local wait_queue variable from the socket's sk_sleep
    queue. This causes havoc further down the road.
    In response to this problem, a patch was made that invoked sock_orphan on
    the socket when receiving a disconnect indication. This is not a good fix,
    as this sets sk_sleep to NULL, causing applications sleeping in recvmsg
    (and other places) to oops.
    This is against the latest net-2.6 and should be considered for -stable
