kdbus: add connection pool implementation

2014-11-20 Thread Greg Kroah-Hartman
From: Daniel Mack A pool for data received from the kernel is installed for every connection of the bus, and it is used to copy data from the kernel to userspace clients, for messages and other information. It is accessed when one of the following ioctls is issued: * KDBUS_CMD_MSG_RECV, to re

kdbus: add node and filesystem implementation

2014-11-20 Thread Greg Kroah-Hartman
From: Daniel Mack kdbusfs is a filesystem that will expose a fresh kdbus domain context each time it is mounted. Per mount point, there will be a 'control' node, which can be used to create buses. fs.c contains the implementation of that pseudo-fs. Exported inodes of 'file' type have their i_fop

kdbus: add header file

kdbus: add name registry implementation

2014-11-20 Thread Greg Kroah-Hartman
From: Daniel Mack This patch adds the name registry implementation. Each bus instantiates a name registry to resolve well-known names into unique connection IDs for message delivery. The registry will be queried when a message is sent with kdbus_msg.dst_id set to KDBUS_DST_ID_NAME, or when a reg

kdbus: add code to gather metadata

2014-11-20 Thread Greg Kroah-Hartman
