[PATCH] selftests: bpf: config: add config fragments

From: Anders Roxell <hidden>
Date: 2018-06-12 11:08:01

Tests test_tunnel.sh fails due to config fragments ins't enabled.

Fixes: 933a741e3b82 ("selftests/bpf: bpf tunnel test.")
Signed-off-by: Anders Roxell <redacted>
---

All tests passes except ip6gretap that still fails. I'm unsure why.
Ideas?

Cheers,
Anders

William (Cc) might be able to help you out.

Applied the one below in the mean-time to bpf, thanks!

Hi Anders,

ip6erspan is based on ip6gretap, does ip6erspan pass?

it did pass  when I was sending the email.
However, I retested this on next-20180613 and now it fails.

Does 'ip -s link show' show any errors/dropped on ip6gretap device?

Thanks

I rerun the test_ip6gretap test only and added "set -x" to
test_tunnel.sh here's the output.
I added "ip -s link show ip6gretap11" before the cleanup function in the script.

So there are 5 errors at TX.

How do I checkin the "next-20180613" source code?

How do I checkin the "next-20180613" source code?
You can find the source code here [1], and I would look in the latest tag that I
said that I was able to reproduce it on above.

but the ipv6 over ipv6 gre fails.
Do you have any firewall rules that block this traffic?
or if possible, the packet might get dropped at function ip6gre_xmit_ipv6
can you print the return value of this function?

Hi Anders,
Hi William,
I'm still not able to reproduce the issue on next-20180620.
I'm not able to reproduce it either, and I tried on todays tag as well
next-20180703.

The only test that is failing in bpf/test_tunnel.sh:

FAIL: xfrm tunnel

Anders
