IPSEC + long UDP causes reproducible crash [was: Crash in ether_input]

e past couple of days. I can't tell if the mbuf is being corrupted as it's passing through the crypto system or if it's happening in ip_fragment. I'm in a bit over my head in terms of trying to isolate and patch the bug. If anyone has the time to squash it or at least give me som

msk link problems on 8.0

fconfig down/up did not help things. At the time, I hadn't discovered the physical down/up workaround, so I can't speak to whether that would have helped (and this error condition hasn't recurred (knock on wood)). I don't know if the issues are related or separate, but if yo

he implementation can highlight.

For example: | ccowart dev-aux etc $ cat /etc/start_if.vlan81 | ifconfig vlan81 vlan 81 vlandev em0 | ifconfig vlan81 inet 10.81.1.1/16 I don't know that two files per interface is any cleaner than a really long /etc/rc.conf (I usually prefer the latter, but I generally am not dealing
