    Problem Summary PG4U.00090 This request claims that UNIX domain sockets need not support O_NONBLOCK semantics.
    Problem Text
    If connect peer issues listen() call in the case of asynchronous mode a UNIX
    domain socket, the test suite expects that connect() a call is successfull.
    But we can't find such a description in CAE specification.

    Review Response
    We recommend this request be refused.

    The connect() spec states that

    If the connection cannot be established immediately and
    O_NONBLOCK is set for the file descriptor for the socket,
    connect() will fail and set errno to [EINPROGRESS], but the
    connection request will not be aborted, and the connection will
    be established asynchronously.

    We believe the submitter assumes that it is possible to pick and
    choose functionality from the the spec that will apply to
    different socket types unless the spec specificly states that the
    functionality is required by that socket type. This is not true.
    All functionality presented by the spec is required for all
    socket types unless the spec specifically states it is optional
    for a socket type.
