AES-NI on 2.2.3-RELEASE broken with non AES-GCM modes
0%
Description
Hi,
Numerous reports are coming in of IPSec not working correctly with the 2.2.3-RELEASE. Multiple failures on site-to-site (seems to be NAT related and UDP), and mobile connection failures (secret keys not working).

Looks like it's related to the AESNI module now attempting to process all AES rather than only AES-GCM. It works fine for AES-GCM, but not others (e.g. AES-256)
Disable AESNI and reboot or temporarily switch to a non-AES cipher in Phase 2 to work around it until we post a fix.

Patch that broke it (ipsec_aescbc_aesni.diff) was reverted. Should be fine on 2.2.4 snapshots

Not sure if it's needed but I can confirm that Disabling AESNI works.

I just hit this issue as well, disabling AES-NI did the trick. It's a bit unfortunate that the release notes/blog post weren't updated with this information.
