selftests/bpf: fix missing BPF object files

2022-10-21T02:05:50Z

After commit afef88e65554 ("selftests/bpf: Store BPF object files with .bpf.o extension"), we should use *.bpf.o instead of *.o. In addition, use the BPF_FILE variable to save the BPF object file name, which can be better identified and modified.

selftests/bpf: Move vxlan tunnel testcases to test_progs

2022-05-10T17:49:03Z

Move vxlan tunnel testcases from test_tunnel.sh to test_progs. And add vxlan tunnel source testcases also. Other tunnel testcases will be moved to test_progs step by step in the future. Rename bpf program section name as SEC("tc") because test_progs bpf loader could not load sections with name SEC("gre_set_tunnel"). Because of this, add bpftool to load bpf programs in test_tunnel.sh.

selftests/bpf: Fix tunnel remote IP comments

2022-03-17T23:08:02Z

In namespace at_ns0, the IP address of tnl dev is 10.1.1.100 which is the overlay IP, and the ip address of veth0 is 172.16.1.100 which is the vtep IP. When doing 'ping 10.1.1.100' from root namespace, the remote_ip should be 172.16.1.100. Fixes: 933a741e3b82 ("selftests/bpf: bpf tunnel test.")

seltests: bpf: test_tunnel: Use ip neigh

2021-09-22T03:40:16Z

The 'arp' command is deprecated and is another dependency of the selftest. Just use 'ip neigh', the test depends on iproute2 already.

selftest/bpf: Add missed ip6ip6 test back

2020-11-10T23:37:45Z

In comment 173ca26e9b51 ("samples/bpf: add comprehensive ipip, ipip6, ip6ip6 test") we added ip6ip6 test for bpf tunnel testing. But in commit 933a741e3b82 ("selftests/bpf: bpf tunnel test.") when we moved it to the current folder, we didn't add it. This patch add the ip6ip6 test back to bpf tunnel test. Update the ipip6's topology for both IPv4 and IPv6 testing. Since iperf test is removed as currect framework simplified it in purpose, I also removed unused tcp checkings in test_tunnel_kern.c.

selftests/bpf: fail test_tunnel.sh if subtests fail

2019-05-28T09:08:57Z

Right now test_tunnel.sh always exits with success even if some of the subtests fail. Since the output is very verbose, it's hard to spot the issues with subtests. Let's fail the script if any subtest fails. Signed-off-by: Stanislav Fomichev Acked-by: Yonghong Song Signed-off-by: Daniel Borkmann

selftests/bpf: bpf tunnel test.

2018-04-26T22:11:14Z

The patch migrates the original tests at samples/bpf/tcbpf2_kern.c and samples/bpf/test_tunnel_bpf.sh to selftests. There are a couple changes from the original: 1) add ipv6 vxlan, ipv6 geneve, ipv6 ipip tests 2) simplify the original ipip tests (remove iperf tests) 3) improve documentation 4) use bpf_ntoh* and bpf_hton* api In summary, 'test_tunnel_kern.o' contains the following bpf program: GRE: gre_set_tunnel, gre_get_tunnel IP6GRE: ip6gretap_set_tunnel, ip6gretap_get_tunnel ERSPAN: erspan_set_tunnel, erspan_get_tunnel IP6ERSPAN: ip4ip6erspan_set_tunnel, ip4ip6erspan_get_tunnel VXLAN: vxlan_set_tunnel, vxlan_get_tunnel IP6VXLAN: ip6vxlan_set_tunnel, ip6vxlan_get_tunnel GENEVE: geneve_set_tunnel, geneve_get_tunnel IP6GENEVE: ip6geneve_set_tunnel, ip6geneve_get_tunnel IPIP: ipip_set_tunnel, ipip_get_tunnel IP6IP: ipip6_set_tunnel, ipip6_get_tunnel, ip6ip6_set_tunnel, ip6ip6_get_tunnel XFRM: xfrm_get_state Signed-off-by: William Tu Signed-off-by: Daniel Borkmann
