This patchset completes netns support, by disabling debugfs entries when not in the default name space, and correctly handling interface stack loops when the parent is in a different name space.

It additionally adds netlink support for most of the information found in debugfs, and is netns aware.

This patchset is based on Andrews v7 series as of May 7th, with the following changes of Sven and myself:

* rebase on current master * fix VID output in TT+claim table * fix kerneldoc for batadv_bla_claim_dump* functions * fix -ENODEV return in batadv_bla_claim_dump * added support for bla backbone table * add own TTVN to mesh_info (required for global translation table) * add own group id to mesh_info (required for bla claim/backbone table) * fix soft_iface reference leak when dumping the claim table * fix function parameter alignments * fix includes

it applies on master plus the following two patches applied:

* batman-adv: fix returned error in batadv_netlink_tp_meter_cancel * batman-adv: remove unused vid local variable in tt seq print

We have tested the setup in our VMs and verified functionality of the provided tables, including big TT tables and bridge loop avoidance.

Corresponding batctl patches will be sent separately.

Cheers, Simon
