[net-next,00/12] mptcp: pm: prep work for new ops and sysctl knobs

Message

Matthieu Baerts March 13, 2025, 10:20 a.m. UTC

Here are a few cleanups, preparation work for the new PM ops, and sysctl
knobs.

- Patch 1: reorg: move generic NL code used by all PMs to pm_netlink.c.

- Patch 2: use kmemdup() instead of kmalloc + copy.

- Patch 3: small cleanup to use pm var instead of msk->pm.

- Patch 4: reorg: id_avail_bitmap is only used by the in-kernel PM.

- Patch 5: use struct_group to easily reset a subset of PM data vars.

- Patch 6: introduce the minimal skeleton for the new PM ops.

- Patch 7: register in-kernel and userspace PM ops.

- Patch 8: new net.mptcp.path_manager sysctl knob, deprecating pm_type.

- Patch 9: map the new path_manager sysctl knob with pm_type.

- Patch 10: map the old pm_type sysctl knob with path_manager.

- Patch 11: new net.mptcp.available_path_managers sysctl knob.

- Patch 12: new test to validate path_manager and pm_type mapping.
