Hello:
I have written an LKM module that uses netfilter to capture packets. These packets
are then sent to a hardware crypto device which after finishing, it's driver calls a callback, which
then calls either an ip_rcv (inbound/decrypt) or an ip_send (outbound/encrypt) to deliver the
packet.
When netfilter captures icmp packets which are destined to the machine for
which the Ipsec module is running on, I get kernel crashes.
It only crashes when the icmp traffic is >= 10Mbits/sec.
Are there some unpublished rules when processing icmp with Netfilter?
Does anyone have some suggestions/recommendations?
thanks
Mike
