When isDefaultGateway is true it automatically sets isGateway to true.
The default route will be added via the (bridge's) gateway IP.
If a default gateway has been configured via IPAM in the same
configuration file, the plugin will error out.
Add a namespace object interface for somewhat cleaner code when
creating and switching between network namespaces. All created
namespaces are now mounted in /var/run/netns to ensure they
have persistent inodes and paths that can be passed around
between plugin components without relying on the current namespace
being correct.
Also remove the thread-locking arguments from the ns package
per https://github.com/appc/cni/issues/183 by doing all the namespace
changes in a separate goroutine that locks/unlocks itself, instead of
the caller having to track OS thread locking.
Previously this code used a run-time map lookup keyed by
runtime.GOOS/GOARCH. This version uses conditional compilation to make
this choice at compile time, giving immediate feedback for unsupported
platforms.
Resolves CNI part of https://github.com/coreos/rkt/issues/1765
Second part would be adding similar lines into kvm flavored macvlan
support (in time of creating macvtap device).
/proc/self/ns/net gives the main thread's namespace, not necessarily
the namespace of the thread that's running the testcases. This causes
sporadic failures of the tests.
For example, with a testcase reading inodes after switching netns:
/proc/27686/task/27689/ns/net 4026532565
/proc/self/ns/net 4026531969
/proc/27686/task/27689/ns/net 4026532565
