Comment # 1 on bug 1106 from Mark Goodwin

some progress - in a container, the NET_ADDR_INDOM (using ioctl(fd,
SIOCGIFCONF, ..) is the same namespace as the host not of the container, but
the NET_DEV_INDOM maps to the net namespace in the container (exported as
/proc/net/dev). So in a container, network.interface.net_addr (and related
metrics) have different instances to the rest of the network.interface metrics.
I'm not sure if this matters, unless there is somewhere in the code that
expects the two indoms to have the same set of instances. This could just be a
kernel bug or anomaly since SIOCGIFCONF doesn't honour the net namespace, but
/proc/net/dev does.

Haven't seen any EPERM issues - maybe that was a different bug, now fixed (IIRC
we fixed a bug sounding a bit similar a while back).
