Title:
Strongswan Charon-systemd fails on ixbge fault with hardware offload
Status in linux package in Ubuntu:
Incomplete
Status in strongswan package in Ubuntu:
Triaged
Bug description:
I am using Strongswan (charon-systems) as a vpn server allowing
external (roadwarrior) users to connect in.
The system worked without problem using a tg3 network interface.
upgrading to a ixbge 10gbe interface causes problems and no traffic
will work between the client/server once the IPSec connection is
established.
dmesg reports :
[42778.201643] ixgbe 0000:07:00.0 ens1f0: ixgbe_ipsec_tx: bad
sa_idx=64512 handle=0
over and over.
I tried upgrading to the HWE kernel but the fault remains.
It only affects the IXBGE interfaces, not the TG3 interfaces (which
suggests it was a kernel fault)
I believe this kernel update fixes it:
