[PATCH mptcp-next v8 0/8] mptcp: use GENL_REQ_ATTR_CHECK in userspace pm

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

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This is a newer version of the series started by Geliang, now making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
