    Problem Report Number 1080
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0536
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1998-06-16 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSRT version 5.0.1
    Test Identification rt.os/priosched/sched_getparam 3, 4
    Problem Summary TSD4R.00004 These tests will fail on implementations which dereference the param argument prior to checking permissions.
    Problem Text
    In the test source file
    tset/rt.os/priosched/sched_getparam/sched_getparam.c
    test3() and test4() both have the code:

    struct sched_param *param;
    ...
    rval = tb_sched_getparam(0, &param);

    Memory for param is never allocated, and the segmentation violation can
    occur when it is accessed. The tests work if the declaration is corrected
    to:

    struct sched_param param;


    Once this is changed, the result for these tests becomes UNSUPPORTED,
    the expected result in our implementation.
    Test Output

    ************************************************************************
    /tset/rt.os/priosched/sched_getparam/T.sched_getparam 3 Unresolved

    Test Description:
    If _POSIX_PRIORITY_SCHEDULING is defined or the implementation
    supports the sched_getparam() function as defined in System Interfaces
    and Headers, Issue 5 and the implementation requires a process to have
    appropriate privilege to get its own scheduling parameters:
    A call to sched_getparam() requesting the scheduling parameters for
    the calling process when the the calling process does not have
    permission to get its own scheduling parameters shall return -1 and
    set errno to EPERM.

    Test Information:
    sched_getparam() succeeded
    unexpected signal 11 (SIGSEGV) received
