Do you have any idea how to get it working? I need to use 3.5.0 kernel due to memory limited embedded device.
Many thanks

History

#1 Updated by Jiri Zendulka over 4 years ago

Correction: With kernel 3.12.10 GCM works fine.

#2 Updated by Noel Kuntze over 4 years ago

Category set to kernel
Status changed from New to Feedback
Assignee set to Noel Kuntze

I strongly doubt that this is a problem of strongSwan, especially because the kernel responds with "Not implemented". Make sure the module for AES-GCM is loaded in the kernel and the modules path is correct.

#3 Updated by Jiri Zendulka over 4 years ago

Yes, you are right. The embedded device has SPEAR320 CPU with C3 crypto accelarator. C3 was enabled in kernel config so all crypto were performed via C3 which does not support GCM.
You can close the issue.

Many thanks.
