The commit [1] ("northd: Add support for stateless ACLs with load balancers")
incorrectly handled connection tracking when enable-stateless-acl-with-lb is
enabled,
causing all stateless traffic in egress to be committed to conntrack.
This fix properly implements the enable-stateless-acl-with-lb behavior by:
When enable-stateless-acl-with-lb is enabled:
- Still sending stateless traffic through connection tracker lookup
in egress.
- Adding new flow in ls_out_stateful to skip committing NEW stateless
connections.
- Only committing established connections for proper return traffic handling.
Fixes: abbc272ac771 ("northd: Add support for stateless ACLs with load
balancers")
