      selftests/bpf: Selftest for sys_sendmsg hooks · 04b6ab73
      由 Andrey Ignatov 提交于 
      Add selftest for BPF_CGROUP_UDP4_SENDMSG and BPF_CGROUP_UDP6_SENDMSG
attach types.

Try to sendmsg(2) to specific IP:port and test that:
* source IP is overridden as expected.
* remote IP:port pair is overridden as expected;

Both UDPv4 and UDPv6 are tested.

Output:

      selftests/bpf: Prepare test_sock_addr for extension · 9be71aa6
      由 Andrey Ignatov 提交于 
      test_sock_addr was not easy to extend since it was focused on sys_bind
and sys_connect quite a bit.

Reorganized it so that it'll be easier to cover new test-cases for
`BPF_PROG_TYPE_CGROUP_SOCK_ADDR`:

- decouple test-cases so that only one BPF prog is tested at a time;

- check programmatically that local IP:port for sys_bind, source IP and
  destination IP:port for sys_connect are rewritten property by tested
  BPF programs.

The output of new version:
  # test_sock_addr.sh 2>/dev/null

      selftests/bpf: Makefile fix "missing" headers on build with -idirafter · 167381f3
      由 Sirio Balmelli 提交于 
      Selftests fail to build on several distros/architectures because of
	missing headers files.

On a Ubuntu/x86_64 some missing headers are:
	asm/byteorder.h, asm/socket.h, asm/sockios.h

On a Debian/arm32 build already fails at sys/cdefs.h

In both cases, these already exist in /usr/include/<arch-specific-dir>,
but Clang does not include these when using '-target bpf' flag,
since it is no longer compiling against the host architecture.

The solution is to:

- run Clang without '-target bpf' and extract the include chain for the
current system

- add these to the bpf build with '-idirafter'

The choice of -idirafter is to catch this error without injecting
unexpected include behavior: if an arch-specific tree is built
for bpf in the future, this will be correctly found by Clang.
