Hi,
This patch-duo adds namespaces support for the Android binder driver. As
discussed in Plumbers 2013, binder is a form of IPC and therefore will be
tied to ipc namespace.
On the ipc-ns side, the implementation is modelled after generic net-ns
pointers (see commit dec827d), but simplified to suit single user/caller
for now, to reduce complexity.
The binder driver registers with ipc-ns and uses the generic pointer to
store and retrieve its namespace data. That is, each namespace maintains
its own binder context manager - which suffices for separation, since all
transactions require binder handles provided by the context manager.
Thanks,
Oren.
