[strongSwan] many cipher/hash modes seems to be unavailable

[Christoph Anton Mitterer]

Hi.

I'm using the Debian sid version of strongswan (without the ikev1
package).
I wanted to use
ike = aes256gcm128-sha512-modp2048
esp = aes256gcm128-sha512-modp2048

but if I set this on both hosts (host-to-host scenario with tunnel mode)
no tunnel seem to be set up.
Instead I get somethink like:
10/02/10 05:10:13 12[NET] sending packet: from 84.16.235.61[500] to
77.37.6.134[500]
10/02/10 05:10:13 03[NET] received packet: from 77.37.6.134[500] to
84.16.235.61[500]
10/02/10 05:10:13 03[ENC] parsed IKE_SA_INIT response 0 [ N(NO_PROP) ]
10/02/10 05:10:13 03[IKE] received NO_PROPOSAL_CHOSEN notify error
10/02/10 05:10:41 00[DMN] signal of type SIGINT received. Shutting down

ipsec listall also shows me just these:

What about all the GCM and CCM modes listed here:
