I've been installing Libreswan on Debian 7.7 Wheezy 64bit VPSes lately but the
post-install script _always_ crashes on first
launch. I always chose not to generate X.509 certificates.
Breaking out of the post-install script via CTRL+C and then using dpkg to
(re)configure Libreswan works well, but I'm not sure
why it crashes in the first place.
It looks likes the kernel's buildin selftest for crypto is failing on a
compress algorithm test? Probably the reason it works for the second
time is that the module is already loaded, so it does not trigger a new
selftest ?
This is really something inside the kernel itself. We might be
triggering it by loading kernel modules, but it is not our code doing
anything bad (as far as I understand the below oops, I don't think you
are trying to use klips (ipsec.ko))
