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.

Merge tag 'rxrpc-rewrite-20160823-1' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Cleanups Here are some cleanups for the AF_RXRPC rewrite: (1) Remove some unused bits. (2) Call releasing on socket closure is now done in the order in which calls progress through the phases so that we don't miss a call actively moving list. (3) The rxrpc_call struct's channel number field is redundant and replaced with accesses to the masked off cid field instead. (4) Use a tracepoint for socket buffer accounting rather than printks. Unfortunately, since this would require currently non-existend arch-specific help to divine the current instruction location, the accounting functions are moved out of line so that __builtin_return_address() can be used. ==================== Signed-off-by: David S.

When we disable SRIOV, we used to unregister the netdev but wasn't freed. But next time when the same netdev is registered, since the state was in 'NETREG_UNREGISTERED', we used to hit BUG_ON in register_netdevice, where it expects the state to be 'NETREG_UNINITIALIZED'. Alloc netdev and register them while configuring SRIOV, and free them when SRIOV is disabled. Also added a new function to setup ethernet properties instead of using ether_setup. Set carrier off by default, since we don't have to do any transmit on the interface.

The function get_netvsc_net_device had conditional locking. This was unnecessary, incorrect, but harmless. It was unnecessary since the code is only called from netlink netdev event callback where RTNL is always acquired before the callbacks are run. It was incorrect because of use of trylock and then continuing. Fix by replacing with proper assertion. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: David S.

Saeed Mahameed says: ==================== Mellanox mlx5 core driver updates 2016-08-20 This series contains several low level and API updates for mlx5 core commands interface and mlx5_ifc.h to be shared as base code for net-next and rdma mlx5 4.9 submissions. From Saeed, ten patches that refactors old layouts of firmware commands which were manually generated before we introduced the mlx5_ifc, now all of the firmware commands inbox/outbox layouts moved to use mlx5_ifc and we remove the old manually generated structures. Plus to those ten patches, we add two patches that unifies mlx5 commands execution interface and improve the driver log messages in that area. From Hadar and Ilya, added the needed hardware bits and infrastructure for minimum inline headers setting and encap/decap commands and capabilities, needed for E-Switch offloads. This series applies on top latest net-next and rdma/master, and smoothly merges with the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch. ==================== Signed-off-by: David S.

Perform terminal call ACK/ABORT retransmission in the connection processor rather than in the call processor. With this change, once last_call is set, no more incoming packets will be routed to the corresponding call or any earlier calls on that channel (call IDs must only increase on a channel on a connection). Further, if a packet's callNumber is before the last_call ID or a packet is aimed at successfully completed service call then that packet is discarded and ignored.

Calculate the serial number skew in the data_ready handler when a packet has been received and a connection looked up. The skew is cached in the sk_buff's priority field. The connection highest received serial number is updated at this time also. This can be done without locks or atomic instructions because, at this point, the code is serialised by the socket. This generates more accurate skew data because if the packet is offloaded to a work queue before this is determined, more packets may come in, bumping the highest serial number and thereby increasing the apparent skew. This also removes some unnecessary atomic ops. Signed-off-by: David Howells <dhowells@redhat.com>
