    Problem Summary fcntl() specifications always require the FD_CLOEXEC flag even when
    exec() is not supported in PSE52.
    Problem Text The fcntl() specifications mention that the FD_CLOEXEC flag is to be
    supported by both the F_DUPFD and F_SETFD commands. The FD_CLEXEC flag
    is strictly related to the usage of the exec() function. However the
    exec() function is not required for a PSE52 conforming system so it
    would be logical that the fcntl() function describes the handling of
    the FD_CLOEXEC flag as optional and depending on an optional
    functionality, but it does not...

    /tset/rt.os/ioprim/fcntl/T.fcntl 1 Failed


    Test Description:
    If _POSIX_SHARED_MEMORY_OBJECTS is defined:
    A call to fcntl(fildes, F_DUPFD, arg) when fildes refers to
    a shared
    memory object shall act as follows:
    a. A new file descriptor is returned;
    b. The returned file descriptor is the lowest numbered
    descriptor
    greater than or equal to arg;
    c. The returned file descriptor describes the same open file
    description as the original descriptor fildes;
    d. The returned file descriptor has the FD_CLOEXEC flag
    clear.


    Test Information:
    FD_CLOEXEC flag is set

    Review Conclusion The claim that PSE52 should allow support for FD_CLOEXEC to be optional
    is perfectly reasonable, and would be grounds for requesting a waiver
    for a test that failed because FD_CLOEXEC could not be set.

    However, that is not what has happened in this test. At the point at
    which the failure occurs, the test has already successfully set
    FD_CLOEXEC for a file descriptor. It then duplicates the fd using
    fcntl(F_DUPFD) and checks that the new fd does not have FD_CLOEXEC set
    (i.e. that the FD_CLOEXEC setting has not been propagated to the
    duplicate fd). On this implementation the setting has been propagated,
    contrary to the requirements of POSIX.1.

    This waiver request is refused.
