    Problem Summary PG4U.00131 This IR claims that EHOSTUNREACH is the proper result.
    Problem Text
    The IUT is setting errno to EHOSTUNREACH under these conditions.
    Default routing is not configured.

    The difference between EHOSTUNREACH and ENETUNREACH
    is very fuzzy and one way it can be interpreted is:
    If the socket (used to connect) has a setsockopt(SO_DONTROUTE),
    the stack should skip the routing tables search for the destination
    host and try to see if there is a direct link to the network of the
    destination. If not then return a ENETUNREACH.
    If this socket does not have this setsockopt(SO_DONTROUTE) set, then
    routing tables should be searched. If no route to the destination
    is found, then EHOSTUNREACH is to be returned.

    Test Output
    TEST CASE: connect

    TEST PURPOSE #15
    If the implementation supports a communications domain
    and a connection-oriented socket type:
    ENETUNREACH in errno and return -1 on a call to int
    connect(int socket, const struct sockaddr *address,
    size_t address_len) when no route to the network is
    present.
    PREP: Create test sockaddr_in: address = 129.40.217.7, port = 63741
    PREP: Change address to configuration parameter VSU_ADDRESS_INVALID
    TEST: AF_INET SOCK_STREAM
    PREP: Create socket
    TEST: Call connect with unreachable address
    TEST: Return value
    TEST: errno value
    ERROR: connect call failed incorrectly, errno was 1130(EHOSTUNREACH - Destination host cannot be reached) should have been
    ENETUNREACH
    15 FAIL

    Review Response
    We recommend this request be refused.

    In the VSU User's Guide, Appendix B.1, the section describing the
    VSU_ADDRESS_INVALID configuration variable states:

    A host address on a network which must be unreachable from the
    platform under test. It may be necessary to disable default routing
    on the platform to meet this condition.

    The SO_DONTROUTE option is not defined by the X/Open Sockets Interface
    and is thus not normative. The IUT must be configured to produce this
    condition through system configuration and without the use of
    non-normative calls.

    If no default route exists as described in the above, then connect()
    should return ENETUNREACH since there is no route to the network is
    present. Otherwise, the system is misconfigured and a default route
    or actual route to the network was found erroneously.
