From: Geliang Tang <tanggeliang@kylinos.cn>

v2:
 - a new patch "hold msk lock before removing id 0 address"

Drop the patch "mptcp: reuse sending nlmsg code in dump_addr", add a new
helper mptcp_pm_genl_fill_addr() to save the duplicated code.

Define struct mptcp_pm_addr_id_bitmap in protocol.h, instead of defining
mptcp_pm_addr_id_bitmap_t in include/net/mptcp.h, since get_addr() and
dump_addr() interfaces of BPF userspace pm is dropped as Matt suggested.

Geliang Tang (7):
  mptcp: add mptcp_pm_genl_fill_addr helper
  mptcp: add struct mptcp_pm_addr_id_bitmap
  mptcp: drop inet6_sk in mptcp_nl_find_ssk
  mptcp: drop match in userspace_pm_append_new_local_addr
  mptcp: hold msk lock before removing id 0 address
  mptcp: update address type of get_local_id
  mptcp: change is_backup interfaces as get_flags

Hi Geliang,

Thank you for your modifications, that's great!

Our CI did some validations and here is its report:

- KVM Validation: normal: Unstable: 1 failed test(s): selftest_mptcp_join 🔴
- KVM Validation: debug: Unstable: 1 failed test(s): selftest_mptcp_join 🔴
- 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/12783407981

Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/0f696004e7a5
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=925568


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 ;-)

It looks the CI spot a regression with this series (and the previous
version as well):

  75 - mptcp_join: remove single address with port

https://github.com/multipath-tcp/mptcp_net-next/actions/runs/12783407981

Do you mind checking that please?

Cheers,
Matt
