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=20
which the Ipsec module is running on, I get kernel crashes.=20

It only crashes when the icmp traffic is >=3D 10Mbits/sec.

Are there some unpublished rules when processing icmp with Netfilter?
Does anyone have some suggestions/recommendations?

thanks
Mike
