v8:
 - move the set_flags() patches out of this set.
 - differences from v6:
  - adjust the order of the patches.
  - keep "pernet = pm_nl_get_pernet(net);" at the beginning of
    mptcp_pm_nl_set_flags().
  - not use NL_SET_ERR_MSG_ATTR in mptcp_pm_nl_set_flags(), since 'attr'
    will be removed in the commit "mptcp: add local & remote parameters for
    set_flags".
  - update the code related mptcp_userspace_pm_remove_id_zero_address()
    since a new patch to drop "info" parameter of this patch is added.
  - add a comment "mptcp_pm_nl_mp_prio_send_ack() only fails in one case"
    in mptcp_userspace_pm_set_flags().

v7:
 - update set_flags() interface.
 - drop 'info' parameter of userspace_pm_remove_id_zero_address().
 - rebase v6 on top of these changes.

This is a newer version of the series started by Geliang, now making
them more uniform on how the NL errors are set, and giving more hints to
the userspace about what's wrong.

Geliang Tang (2):
  mptcp: drop info of userspace_pm_remove_id_zero_address
  mptcp: pm: userspace: use GENL_REQ_ATTR_CHECK

Matthieu Baerts (NGI0) (6):
  mptcp: pm: userspace: flags: clearer msg if no remote addr
  mptcp: pm: more precise error messages
  mptcp: pm: improve error messages
  mptcp: pm: remove duplicated error messages
  mptcp: pm: mark missing address attributes
  mptcp: pm: use NL_SET_ERR_MSG_ATTR when possible

Hi Matthieu,

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/12662643252

Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/f845d68f8495
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=923191


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 ;-)

Because there are still some discussions ongoing on that patch, and not
to block this series here that is almost ready, I think it might be
easier to keep these modifications in 'set_flags()' here. The other
series can be rebased on top of this one (with a "Based-on:" if needed).

With this modification (and moving the changelog to the comment section
+ maybe keeping GENL_REQ_ATTR_CHECK() at the top), I think we can merge
this series.

WDYT?

Cheers,
Matt
