Subject: [PATCH 0/5] Add namespace awareness to Netlink methods

Currently, Netlink has partial support for acting outside of the current
namespace.  It appears that the intention was to extend this to all the
methods eventually, but it hasn't been done to date.

With this series RTM_SETLINK, RTM_NEWLINK, RTM_NEWADDR, and RTM_NEWNSID
are extended to respect the selection of the namespace to work in.

Jonas Bonn (5):
  rtnetlink: allow RTM_SETLINK to reference other namespaces
  rtnetlink: skip namespace change if already effect
  rtnetlink: allow RTM_NEWLINK to act upon interfaces in arbitrary
    namespaces
  net: ipv4: allow setting address on interface outside current
    namespace
  net: namespace: allow setting NSIDs outside current namespace
