[CRIU] [PATCH 00/12] Dump and restore internal veth devices

[Andrei Vagin]

From: Andrei Vagin <avagin at virtuozzo.com>

This series adds support for internal veth devices. Here is no tricks.
We create a veth pair and for one of these devices we set a netns id
where it has to be created. Another device is created in the current
network namespace.

Andrei Vagin (12):
  images: add a network namespace id into images
  kerndat: check whether a kernel supports netns id-s or not
  netlink: add nla_get_s32()
  net: transfer ns_id structures to functions about c/r-ing netns
  netns: create a netlink route socket out of dump_links()
  netns: dump and restore network namespace ID-s
  net: give ns_id to link_info functions
  netns: restore internal veth devices
  net: split restore_links on read and restore parts
  net: create a list of all links
  net: dump and restore connected to a bridge links
  test: check veth devices from two network namespaces
