Re: [strongSwan] Kernel panic with VTI tunnel

For reference, this is the kernel bug report, including a fix, for kernel crashes when using a VTI tunnel: https://bugzilla.kernel.org/show_bug.cgi?id=95211 Not sure if it is VTI specific though. Regards, Mike On 22 March 2015 at 14:31, Mike Noordermeer m...@normi.net wrote: FYI, the issue is

FYI, the issue is still present in the latest 4.0 kernel, so VTI tunnels seem to be fairly unusable at the moment (at least for me they are). I filed a kernel bug at https://bugzilla.kernel.org/show_bug.cgi?id=95211 I'll probably switch to a GRE tunnel for the time being. Regards, Mike On 16

Hi, In the mail conversation, Steffen mentions that the patch should never be necessary, since outer_mode should not become NULL. So I doubt the patch would be the proper fix? It may fix this issue, but if the maintainer says the patch should not be necessary it seems like the wrong fix to me.

Hi, Do you happen to have any more specific info on this bugfix? I would rather not deviate from the Debian default kernels, so it would be nice if I could point the maintainers to a specific fix that should be backported. Thanks, Mike On 15 March 2015 at 17:02, Andre Valentin

Thanks... that looks very much like the same bug indeed. I will diff the various files of the Debian kernel and 3.18 vanilla to see if I can spot the change that introduced it. Regards, Mike On 16 March 2015 at 09:42, André Valentin avalen...@marcant.net wrote: Hi, take a look at this
