This patch-set add multicast support to Unix domain socket familiy for datagram and seqpacket sockets. This work was made by Alban Crequy as a result of a research we have been doing to improve the performance of the D-bus IPC system. The first approach was to create a new AF_DBUS socket address family and move the routing logic of the D-bus daemon to the kernel. The motivations behind that approach and the thread of the patches post can be found in  and . The feedback was that having D-bus specific code in the kernel is a bad idea so the second approach was to implement multicast Unix domain sockets so clients can directly send messages to peers bypassing the D-bus daemon. A previous version of the patches was already posted by Alban  who also has a good explanation of the implementation on his blog . http://alban-apinc.blogspot.com/2011/12/d-bus-in-kernel-f... http://thread.gmane.org/gmane.linux.kernel/1040481 http://thread.gmane.org/gmane.linux.network/178772 http://alban-apinc.blogspot.com/2011/12/introducing-multi... The patch-set is composed of the following patches: [PATCH 01/10] af_unix: Documentation on multicast unix sockets [PATCH 02/10] af_unix: Add constant for unix socket options level [PATCH 03/10] af_unix: add setsockopt on unix sockets [PATCH 04/10] af_unix: create, join and leave multicast groups with setsockopt [PATCH 05/10] af_unix: find the recipients of a multicast group [PATCH 06/10] af_unix: Deliver message to several recipients in case of multicast [PATCH 07/10] af_unix: implement poll(POLLOUT) for multicast sockets [PATCH 08/10] af_unix: Unsubscribe sockets from their multicast groups on RCV_SHUTDOWN [PATCH 09/10] Allow server side of SOCK_SEQPACKET sockets to accept a new member [PATCH 10/10] af_unix: Add a peer BPF for multicast Unix sockets -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to firstname.lastname@example.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
