Subject: [PATCH 1/2] ipc namespace: a generic per-ipc pointer and peripc_ops
|
|
||||||
|
|
||||||
Add a void * pointer to struct ipc_namespace. The access rules are:
|
|
||||||
1. (un)register ops with (un)register_peripc_operations()
|
|
||||||
2. call ipc_assign_generic() to put private data on the ipc_namespace
|
|
||||||
3. call ipc_access_generic() to access the private data
|
|
||||||
4. do not change the pointer during the lifetime of ipc_namespace
|
|
||||||
|
|
||||||
Modeled after generic net-ns pointers (commit dec827d), but simplified
|
|
||||||
to accommodate a single user for now (reduce code churn):
|
|
||||||
5. only one caller can register at a time
|
|
||||||
6. caller must register at boot time (not to be used by modules)

Subject: [PATCH 2/2] binder: implement namepsace support for Android binder
|
|
||||||
driver
|
|
||||||
|
|
||||||
Add namespaces support for the Android binder driver.
|
|
||||||
As binder is an IPC mechanism, tie its namespace to IPC_NS.
|
|
||||||
|
|
||||||
In binder, the first process to call BINDER_SET_CONTEXT_MGR ioctl
|
|
||||||
becomes the manager with context 0, and thereafter IPC is realized
|
|
||||||
through binder handles obtained from this manager.
|
|
||||||
|
|
||||||
For namespaces, associate a separate binder state with each namespace
|
|
||||||
so each namespace has its own context manager. Binder users within a
|
|
||||||
namespace interact only with the context manager there. This suffices
|
|
||||||
because binder does not allow IPC not via the context manager.
|
|
||||||
|
|
||||||
Currently, statistics remain global, except for the list of processes
|
|
||||||
that hold an open binder device (reported per namespace).
