    Problem Summary PG4C.00108 This IR claims that recursively copied directories be created using only umask before subdirectories and files are copied.
    Problem Text

    Assertion 1004 calls ga10.sh to test cp -R using different umask
    settings. The tests attempts to use a umask of 0177, this will
    create the toplevel directory copied with permissions of
    rw-------. This will not allow the creation of any files or
    directories in the directory created. Thus the cp -R fails because
    the lower level directories/files can not be created. The code in
    ga10 is the following:

    # Try umask=0177 = --xrwxrwx = "u=rw,go-rwx"
    umask u=rw,go-rwx
    rm -rf $_ga10_newfile
    eval $@ > /dev/null 2>&1
    _mode=`GetFileData $_ga10_newfile Mode`
    rm -rf $_ga10_newfile
    # Determine expected mode:
    _expected_mode=`_ga10_check_mode -$_lltype $_lltype$_defaultmode
    `
    if ! expr "X$_mode" : "X$_expected_mode" >/dev/null 2>&1
    then
    umask $_savemask
    echo "Failure: file mode '$_mode' did not match RE '$_ex
    pected_mode'."
    return $VSC_FAILURE
    fi

    The no permission error message in the ga10_errlog is from the
    eval $@ line. The other error is because the directory was not
    created.

    Review Response
    We recommend this request be refused.

    We believe the test is correct. The standard for cp states in
    the Description section:

    2.

    e. If the directory dest_file does not exist, it will be created
    with file permission bits set to the same value as those of
    source_file, modified by the file creation mask of the user if
    the -p option was not specified, and then bitwise inclusively
    ORed with S_IRWXU.

    This requires created directories explicitly allow read/write/execute
    for the owner, but to preserve the permissions for group and other.

    The IUT is not conforming to this requirement.

    Read/write/execute permission is necessary for files to be copied into
    the directory in step f. Otherwise, readonly directories cannot be
    copied recursively.

    f. The files in the directory source_file will be copied to the
    directory dest_file, taking the four steps [1-4] listed here
    with the files as source_files.

    Finally, the proper directory permissions are set for the directory in
    step g:

    g. If dest_file was created, its file permission bits will be
    changed (if necessary) to be the same as those of source_file,
    modified by the file creation mask of the user if the -p
    option was not specified.

    Given the following directory/file combination

    dir1 perm=777 rwxrwxrwx
    dir1/file1 perm=666 rw-rw-rw-

    The sequence of events occurring for cp -R dir1 dir2 when umask
    is set to 177 are as follows:

    # Create the directory
    mkdir dir2
    # use umask, but allow files to be manipulated by
    # owner, so with umask 177 we get an initial mode of
    # 600 or'ed with 700 (S_IRWXU).
    chmod dir2 to (600 | 700) = rw------- | rwx------ = rwx------
    # copy subdirectory files
    cp dir1/file1 dir2/file1
    # fix up permissions to reflect what it should have been for
    # a newly created directory
    chmod dir2 to 600 = rw-------
