[strongSwan] "unable to add pseudo IPIP SA with SPI c1bb6ffe: Invalid argument"

[Tobias Brunner]

Hi,

> strongswan4-mod-kernel-klips - 4.5.2-1

Please try to remove this module from your build.  The kernel-klips
plugin was done for a very specific (and rather old) KLIPS release.  And
depending on whether your kernel actually includes the KLIPS patch or
not might never work.  So, do you actually use KLIPS?  If so, you might
have to go back to a 2.x strongSwan release that supported KLIPS.  If
not, then just use the kernel-netlink plugin.

Regards,
Tobias
