I'm using 2.6.32-5 kernel to developp, but the function itself didn't
seem to have been updated in the 2.6.38 kernel.
You really should use 2.6.39 kernel for your dev...
It is a long-term work (started in October 2010), plus I rely on Xtables
to develop it, I used a stable kernel, as my module does not involve
kernel re-compilation.
The modification I had to apply is to re-execute the routing process on
the incoming paquet in order to get the ICMP packet sent:
instead of the simple
if (!rt)
// goto out;
Is there an other reason why the rtable of the incoming packet was not set?
It is set by caller.
check ip_rcv_finish()
Also please take a look at commit 64f3b9e203bd06855
net: ip_expire() must revalidate route
[ Since I understand from a prior mail that you maybe queued an skb for
a while for your defrag purpose ]
It is a packet that has just been matched by an iptables rule (my module
is simply branched on a hook), so no queue for it.
So i just should just process the routing before calling the icmp_send()
function?
