Hi All,
I have a question in the IP input code. If we are able to find the next
for a source routed packet why do we change the destination address of the
packet.
in the file ip_input.c we have the code
ip->ip_dst = ipaddr.sin_addr;
(void)memcpy(cp + off, &(IA_SIN(ia)->sin_addr),
sizeof(struct in_addr));
cp[IPOPT_OFFSET] += sizeof(struct in_addr);
/*
* Let ip_intr's mcast routing check handle mcast
pkts
*/
forward = !IN_MULTICAST(ntohl(ip->ip_dst.s_addr));
break;
Regards
Kshitij
