and try to download my mail using mail/offlineimap.  With both GENERIC and
GENERIC.MP from the April 14 snapshot, running mail/offlineimap triggers the
following panic (transcribed by hand below).

>How-To-Repeat:

The panic appears both with GENERIC and GENERIC.MP kernels whenever I
to connect my laptop to the WLAN as usual and try to run offlineimap and
vpnc as follows:

$ cat .offlineimaprc
[general]
accounts = main

[Account main]
localrepository = main-local
remoterepository = main-remote
status_backend = sqlite

[Repository main-local]
type = Maildir
localfolders = /home/theo/.Maildir

[Repository main-remote]
type = IMAP
remotehost = mail.ethz.ch
remoteuser = <my user>
remoteport = 993
ssl = yes
cert_fingerprint = b8e69443b92a4134c0becd1bdf7198f8b79cc1fb

$ cat /etc/vpnc/ethz.conf
Interface name tun0
IKE DH Group dh2
IPSec gateway <gateway>
IPSec ID <ipsec-id>
IPSec secret <ipsec-secret>
Xauth username <username>

$ # the following is done according to security/vpnc/pkg/MESSAGE:
$ sudo sysctl net.inet.esp.enable=0 net.inet.esp.udpencap=0

        Establishing connection to mail.ethz.ch:993
panic: ipintr no HDR
...


>Fix/Workaround:

It seems likely that the panic has to do with this commit:
https://marc.info/?l=openbsd-cvs&m=142867432629365&w=2
see also:
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/netinet/ip_input.c.diff?r1=1.247&r2=1.248&f=h

I have a GENERIC.MP kernel compiled from freshly updated sources just two hours
before this commit with which I am unable to reproduce this panic.
