Hangbin Liu says: ==================== In comment173ca26e9b("samples/bpf: add comprehensive ipip, ipip6, ip6ip6 test") we added some bpf tunnel tests. In commit933a741e3b("selftests/bpf: bpf tunnel test.") when we moved it to the current folder, we missed some points: 1. ip6ip6 test is not added 2. forgot to remove test_ipip.sh in sample folder 3. TCP test code is not removed in test_tunnel_kern.c In this patch set I add back ip6ip6 test and remove unused code. I'm not sure if this should be net or net-next, so just set to net. Here is the test result: ``` Testing IP6IP6 tunnel... PING ::11(::11) 56 data bytes --- ::11 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 63ms rtt min/avg/max/mdev = 0.014/1028.308/2060.906/841.361 ms, pipe 2 PING 1::11(1::11) 56 data bytes --- 1::11 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 48ms rtt min/avg/max/mdev = 0.026/0.029/0.036/0.006 ms PING 1::22(1::22) 56 data bytes --- 1::22 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 47ms rtt min/avg/max/mdev = 0.030/0.048/0.067/0.016 ms PASS: ip6ip6tnl ``` v3: Add back ICMP check as Martin suggested. v2: Keep ip6ip6 section in test_tunnel_kern.c. ==================== Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
