The flag XT_STRING_FLAG_IGNORECASE indicates case insensitive string matching. netfilter can find cmd.exe, Cmd.exe, cMd.exe and etc easily. A new revision 1 was added, in the meantime invert of xt_string_info was moved into flags as a flag. If revision is 1, The flag XT_STRING_FLAG_INVERT indicates invert matching.
