Hi,

I have applied the ipv4options patch to the iptables/netfilter
function, and have some questions:

How is the srr flag/register used in iptables? It is defined as a char,
but how are the bits used? An example in the code makes a binary AND
between the srr and a "boolean" (the is_strictroute). Is it because bit
0 in the srr register contains the relevant info? Or how should I
understand the example below:

else if ((info->options & IPT_IPV4OPTION_MATCH_LSRR) ==
IPT_IPV4OPTION_MATCH_LSRR) {
		if (!((opt->srr) & (!opt->is_strictroute)))
			return 0;
	}

Hope you can help me, thanks!!
