There is samples/bpf/sockex3_kern.c, which exercises it. To
run it, it would be (clang/llvm needed due to BPF backend not
available in gcc):
# cd samples/bpf
# make
# ./sockex3
IP src.port -> dst.port bytes packets
127.0.0.1.12865 -> 127.0.0.1.49711 148 2
127.0.0.1.49711 -> 127.0.0.1.12865 108 2
[...]
Inside parse_eth_proto(), it will do tail calls based on the
eth protocol. Over time, we'll move such C based tests over to
tools/testing/selftests/bpf/.
Ok, after a lot of work setting up an LLVM/CLANG environment and other
things, I implemented tail call support and got this working.
Thanks for the pointers.
Awesome, thanks!
