Hi all,
I'm trying to modify the data passed to ip6_xmit (in ip6_output.c)...
The new data will be a bit larger, so I use skb_push to increase the data
size in skb (after making sure that there is enough headroom for both
my data and all extension headers):
skb->h.raw = skb_push(skb,required_size);
This works perfectly fine... until I update the payload size (which will
be inserted in the IPv6 header later):
seg_len += required_size;
If I update seg_len, my computer freezes (no oops, no kernel panic).
If I don't update it, I will (of course) get truncated packets.
The point that drives me insane is that everything works fine when
inserting extension headers!
I'm working with kernel ver. 2.4.0-test9. My network tests use the lo
loopback device.
Anyone any ideas? Any help would be really appreciated...
Stefan.
