[strongSwan] AESNI and PCLMULQDQ support for Strongswan

[Igor Lopez Orbe]

Hello everyone,

I am trying to set up the AESNI support AES-GCM using the following
encryption algorithm in the ipsec.conf:
esp=aes128gcm16!

I have recompiled the kernel to add AESNI support and
ghash_clmulni_intel support but unfortunately when i set up the VPN i
check the ghash_clmulni_intel module and is never used. Does anyone
know if there is another cipher algorithm in strongswan to force to
use ghash_clmulni_intel module?

This functionality should be supported because in the following
Intel's Whitepaper they use strongswan with this support:

Any idea?

Thank you in advance,
