System: FreeBSD jsite.lefort.net 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Tue Jan 25 10:48:58 CET 2005 jylefort@jsite.lefort.net:/usr/obj/usr/src/sys/JSITE i386
>Description:
Reproducible panics on 5.3-RELEASE when using a FAST_IPSEC IPv6 tunnel
(the kernel panics when processing the first IPv6 packet), both with
mpsafenet=1 and mpsafenet=0. Removing the IPv6 entries from
/etc/ipsec.conf "fixes" the issue.
>How-To-Repeat:
add an IPsec v6 tunnel to /etc/ipsec.conf, eg:
add 2001:838:339::1 2001:838:339::2 esp 15700 -E blowfish-cbc "xxx";
add 2001:838:339::2 2001:838:339::1 esp 24500 -E blowfish-cbc "xxx";
spdadd 2001:838:339::2 ::/0 any -P out ipsec
esp/tunnel/2001:838:339::2-2001:838:339::1/use;
spdadd ::/0 2001:838:339::2 any -P out ipsec
esp/tunnel/2001:838:339::1-2001:838:339::2/use;
$ /etc/rc.d/ipsec reload
$ ping6 www.kame.net
