Merge tag 'rxrpc-rewrite-20160823-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says: ==================== rxrpc: Miscellaneous improvements Here are some improvements that are part of the AF_RXRPC rewrite. They need to be applied on top of the just posted cleanups. (1) Set the connection expiry on the connection becoming idle when its last currently active call completes rather than each time put is called. This means that the connection isn't held open by retransmissions, pings and duplicate packets. Future patches will limit the number of live connections that the kernel will support, so making sure that old connections don't overstay their welcome is necessary. (2) Calculate packet serial skew in the UDP data_ready callback rather than in the call processor on a work queue. Deferring it like this causes the skew to be elevated by further packets coming in before we get to make the calculation. (3) Move retransmission of the terminal ACK or ABORT packet for a connection to the connection processor, using the terminal state cached in the rxrpc_connection struct. This means that once last_call is set in a channel to the current call's ID, no more packets will be routed to that rxrpc_call struct. ==================== Signed-off-by: David S.
