This patch extends the MPTCP test base, to test the new helper bpf_skc_to_mptcp_sock(). Define struct mptcp_sock in bpf_tcp_helpers.h, use bpf_skc_to_mptcp_sock to get the msk socket in progs/mptcp_sock.c and store the infos in socket_storage_map. Get the infos from socket_storage_map in prog_tests/mptcp.c. Add a new function verify_msk() to verify the infos of MPTCP socket, and rename verify_sk() to verify_tsk() to verify TCP socket only. v2: Add CONFIG_MPTCP check for clearer error messages v4: - use ASSERT_* instead of CHECK_FAIL (Andrii) - drop bpf_mptcp_helpers.h (Andrii) v5: - some 'ASSERT_*' were replaced in the next commit by mistake. - Drop CONFIG_MPTCP (Martin) - Use ASSERT_EQ (Andrii) Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net> Link: https://lore.kernel.org/bpf/20220519233016.105670-5-mathew.j.martineau@linux.intel.com
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.
