SystemServer only allowed a single socket to be created for a service before this. Now, SystemServer will allow any amount of sockets. The sockets can be defined like so: [SomeService] Socket=/tmp/portal/socket1,/tmp/portal/socket2,/tmp/portal/socket3 SocketPermissions=660,600 The last item in SocketPermissions is applied to the remainder of the sockets in the Socket= line, so multiple sockets can have the same permissions without having to repeat them. Defining multiple sockets is not allowed for socket-activated services at the moment, and wouldn't make much sense anyway. This patch also makes socket takeovers more robust by removing the assumption that the socket will always be passed in fd 3. Now, the SOCKET_TAKEOVER environment variable carries information about which endpoint corresponds to which socket, like so: SOCKET_TAKEOVER=/tmp/portal/socket1:3 /tmp/portal/socket2:4 and LocalServer/LocalService will parse this automatically and select the correct one. The old behavior of getting the default socket is preserved so long as the service only requests a single socket in SystemServer.ini.
