    Problem Text

    In the source file tset/POSIX.os/dataform/tar/tar2.c the following is
    found:

    /* Remove the file */
    (void) rmdir(p2);
    err = errno;

    /* Check it has really gone */
    if(stat(p2, &stbuf) != SYSERROR || err != ENOENT)
    {
    if(!test_fail++)
    xx_rpt(DELETION);
    in_rpt("rmdir() did not remove directory %s", p2);
    in_rpt("errno = %d - %s", err, errname(err));
    break;
    }
    else
    PATH_TRACE;

    Several problems exist with this code. First note that errno is not set to
    zero prior to the rmdir() call. Thus if the rmdir() is successful the err
    will be set to the prior errno. In this case errno is set to EACCESS(13) in
    the routine init_head(). Note, there appears to be a lack of return value/errno
    checking in init_head(). The path under test A/D1/ appears to be a special
    case and the directory is created during the call to init_pathres() earlier
    in the testcase. The other directories used in this testcase are not created.
    Thus when the rmdir() is executed err is set to ENOENT (2) and they pass the
    stat() check. When rmdir(A/D1) is executed, errno does not change and err is
    set to EACCESS (13). The directory is removed but the stat() check fails and
    the testcase reports unresolved.

    Also the line
    if(stat(p2, &stbuf) != SYSERROR || err != ENOENT)
    is incorrect. Since directory A/D1 must be removed, err will be zero
    (if the above is corrected) this check will fail when the rmdir() has succeed.
    Inserting a errno=0 statement before the rmdir() statement demonstrates this.
