[strongSwan] Several "cannot open shared object file" lines in charon.log

[Groleo Marius]

Hi,

I'm testing strongswan 4.2.9-1 on Ubuntu and I'm getting these
messages in /var/log/charon.log

01[LIB] loading plugin 'aes' failed:
/usr/lib/ipsec/plugins/libstrongswan-aes.so: cannot open shared object
file: No such file or directory
01[LIB] loading plugin 'des' failed:

01[LIB] loading plugin 'sha2' failed:
/usr/lib/ipsec/plugins/libstrongswan-sha2.so: cannot open shared
object file: No such file or directory

Any idea what's happening , beside the file missing ?

Another question would be if AES-GCM is supported on any of the Linux
2.6.x kernels.

Thank you.
