From: Geliang Tang <tanggeliang@kylinos.cn>

v3:
 - check sock_owned_by_user_nocheck(sk)/spin_is_locked(&sk->sk_lock.slock),
   instead of lockdep_sock_is_held(sk).
 - add "sizeof" and "alignof" checks.
 - drop bpf_mptcp_sk() and bpf_mptcp_subflow_tcp_sock() definitions. Use
   bpf_skc_to_mptcp_sock() and mptcp_subflow_tcp_sock() in mptcp_subflow
   bpf_iter selftests instead.

v2:
 - add CONFIG_LOCKDEP check in patch 2 to fix the build error reported
   by CI.

Address Martin's comments in v1.

Hi Geliang,

Thank you for your modifications, that's great!

Our CI did some validations and here is its report:

- KVM Validation: normal: Critical: Global Timeout ❌
- KVM Validation: debug: Success! ✅
- KVM Validation: btf-normal (only bpftest_all): Success! ✅
- KVM Validation: btf-debug (only bpftest_all): Success! ✅
- Task: https://github.com/multipath-tcp/mptcp_net-next/actions/runs/12230234356

Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/c420a7ab2b44
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=915780


If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:

    $ cd [kernel source code]
    $ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
        --pull always mptcp/mptcp-upstream-virtme-docker:latest \
        auto-normal

For more details:

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)

But sadly, our CI spotted some issues with it when trying to build it.

Feel free to reply to this email if you cannot access logs, if you need
some support to fix the error, if this doesn't seem to be caused by your
modifications or if the error is a false positive one.
