[strongSwan] charon-systemd: 11[KNL] received netlink error: No such file or directory (2)

Hi,


when we try to use the CHACHA20_POLY1305 Algo for the child encryption 
we have a strange error.

On our ubuntu test systems everything works fine. Both sides agree on 
that algo for the child. No problem.


On the embedded device we have the following logs entries:

SYS DLOG 346 log info verbose 1 charon-systemd: 11[CHD] CHILD_SA 
imx-nad{1004} state change: CREATED => INSTALLING
SYS DLOG 346 log info verbose 1 charon-systemd: 11[CHD]   using 
CHACHA20_POLY1305 for encryption
SYS DLOG 346 log info verbose 1 charon-systemd: 11[CHD] adding inbound 
ESP SA
SYS DLOG 346 log info verbose 1 charon-systemd: 11[KNL] received netlink 
error: No such file or directory (2)
SYS DLOG 346 log info verbose 1 charon-systemd: 11[KNL] unable to add 
SAD entry with SPI c106f683 (FAILED)

lsmod shows that the module is loaded:

# lsmod
Module                  Size  Used by
chacha_generic         16384  0
poly1305_generic       16384  0
chacha20poly1305       20480  0

Any ideas what might be wrong in the setup? Any  ideas howto debug further?


Mit freundlichen Grüßen,
