[PATCH bpf-next 00/10] selftests/bpf: Retire bpf_tcp_helpers.h

[Martin KaFai Lau <martin.lau@linux.dev>]

From: Martin KaFai Lau <martin.lau@kernel.org>

The earlier commit 8e6d9ae2e09f ("selftests/bpf: Use bpf_tracing.h instead of bpf_tcp_helpers.h")
removed the bpf_tcp_helpers.h usages from the non networking tests.

This patch set is a continuation of this effort to retire
the bpf_tcp_helpers.h from the networking tests (mostly tcp-cc related).

The main usage of the bpf_tcp_helpers.h is the partial kernel
socket definitions (e.g. sock, tcp_sock). New fields are kept adding
back to those partial socket definitions while everything is available
in the vmlinux.h. The recent bpf_cc_cubic.c test tried to extend
bpf_tcp_helpers.c but eventually used the vmlinux.h instead. To avoid
this unnecessary detour for new tests and have one consistent way
of using the kernel sockets, this patch set retires the bpf_tcp_helpers.h
usages and consolidates the tests to use vmlinux.h instead.

Martin KaFai Lau (10):
  selftests/bpf: Remove bpf_tracing_net.h usages from two networking
    tests
  selftests/bpf: Replace the bpf_tcp_helpers.h usage with
    bpf_tracing_net.h in some obvious tests
  selftests/bpf: Add a few tcp helper functions and macros to
    bpf_tracing_net.h
  selftests/bpf: Reuse the tcp_sk() from the bpf_tracing_net.h
  selftests/bpf: Sanitize the SEC and inline usages in the bpf-tcp-cc
    tests
  selftests/bpf: Rename tcp-cc private struct in bpf_cubic and bpf_dctcp
  selftests/bpf: Use bpf_tracing_net.h in bpf_cubic
  selftests/bpf: Use bpf_tracing_net.h in bpf_dctcp
  selftests/bpf: Remove bpf_tcp_helpers.h usage in other misc bpf tcp-cc
    tests
  selftests/bpf: Retire bpf_tcp_helpers.h
