This breaks IPv6 completely if CONFIG_LWTUNNEL is disabled. When that
happens, seg6_iptunnel_init fails with EOPNOTSUPP and the stack fails
to initialize:
=====
NET: Registered protocol family 10
IPv6: Attempt to unregister permanent protocol 6
IPv6: Attempt to unregister permanent protocol 136
IPv6: Attempt to unregister permanent protocol 17
NET: Unregistered protocol family 10
=====
Not sure how to fix this. The following makes IPv6 work again, but I
suspect it mostly defeats the purpose of having SRH on by default:
+#ifdef CONFIG_LWTUNNEL
err = seg6_iptunnel_init();
if (err)
goto out_unregister_pernet;
+#endif
Enabling CONFIG_LWTUNNEL also makes IPv6 work again.
The breakage was caught by the kernel test robot, but the message was
not particularly scary:
