    Problem Report Number 1573
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0855

    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.1.2
    Test Identification CAPI.os/procenv/setpriori 9
    Problem Summary TSD4U.00316 The tests fail if VSX_GID1 happens to correspond to an existing process ID.
    Problem Text
    In both cases, the test appears to be confusing group id and
    process group id.

    For setprio we see it fail at:

    TEST: setpriority(PRIO_PGRP, gid, priority) returns -1 and sets
    errno to ESRCH since no process exists belonging
    to the process group 'gid'

    For getprio we see it fails at:

    TEST: getpriority(PRIO_PGRP, gid) returns -1 and sets
    errno to ESRCH since no process exists belonging
    to the process group 'gid'

    In both cases the test is checking that the process belongs to a
    process group "gid". In both tests, the code uses not_inuse_gid1
    and sets this value to VSX_GID, in the case 151, when it should be
    using the process group id.

    if ((not_inuse_gid1 = get_conf_gid("VSX_GID1")) == -1)
    return;

    Looking at the processes running on the system we see there are
    process with pgid's in the range of VSX_GID.

    UID PID PPID PGID SID C STIME TTY TIME CMD
    root 149 1 149 149 0 Aug 14 ? 0:01 /usr/sbin/rpcbind
    root 132 1 131 131 0 Aug 14 ? 0:36 /usr/sbin/in.routed
    root 152 1 152 152 0 Aug 14 ? 0:00 /usr/sbin/keyserv
    root 238 1 238 238 0 Aug 14 ? 0:00 /usr/lib/power/powerd

    By changing part of setpriori 9 as follows we can make the test
    pass.

    pid_t pgid;

    pgid = vfork()
    if (pgid == -1) {
    uwerrno("fork");
    return;
    }
    if (pgid == 0) {
    exit (0);
    }
    waitpid (pgid, &result, 0);
