Stephen Smalley 79af73079d Add security hooks to binder and implement the hooks for SELinux. ... Add security hooks to the binder and implement the hooks for SELinux. The security hooks enable security modules such as SELinux to implement controls over binder IPC. The security hooks include support for controlling what process can become the binder context manager (binder_set_context_mgr), controlling the ability of a process to invoke a binder transaction/IPC to another process (binder_transaction), controlling the ability of a process to transfer a binder reference to another process (binder_transfer_binder), and controlling the ability of a process to transfer an open file to another process (binder_transfer_file). These hooks have been included in the Android kernel trees since Android 4.3. (Updated to reflect upstream relocation and changes to the binder driver, changes to the LSM audit data structures, coding style cleanups, and to add inline documentation for the hooks).
