Hi there,
I'm using OpenBSD 4.1-stable/amd64 (dmesg below). I'm setting up ipsec to
secure my wireless network, and that seems to work great. (Great job on the
new way to configure ipsec, by the way!)
When using tcpdump on the enc0 interface, I noticed that it segfaults after
a few seconds of continuous traffic on enc0. The weird thing is, I can't
get it to produce a coredump to post a bugreport (unfortunately, I'm no
programmer so I don't think I can diagnose and fix it myself). I'm probably
missing something here, so a nudge in the right direction would be much
appreciated. ulimit -c is unlimited, I have the default login.conf, I set
kern.nosuidcoredump=0, and executed tcpdump from /tmp. Still no corefile.
tcpdump is invoked as follows:
tcpdump -n -p -i enc0
The output is:
tcpdump: WARNING: enc0: no IPv4 address assigned
tcpdump: listening on enc0, link-type ENC
tcpdump: WARNING: compensating for unaligned libpcap packets

What can I do to (help) find the cause of this?
