acl_calc_mask() function is a POSIX.1e call that
  calculates and set the permissions associated with the
  ACL_MASK ACL entry of the ACL referred to by
  acl_p.
The value of new permissions are the union of the permissions
    granted by the ACL_GROUP,
    ACL_GROUP_OBJ, ACL_USER tag
    types which match processes in the file group class contained in the ACL
    referred to by acl_p.
If the ACL referred to by acl_p already
    contains an ACL_MASK entry, its permissions shall be
    overwritten; if it does not contain an ACL_MASK
    entry, one shall be added.
acl_calc_mask() function returns the value 0
  if successful; otherwise the value -1 is returned and the global
  variable errno is set to indicate the error.
acl_calc_mask() function fails if:
EINVAL]acl_calc_mask() function was added in
  FreeBSD 5.0.
