Pull networking updates from David Miller: "Highlights: 1) Steady transitioning of the BPF instructure to a generic spot so all kernel subsystems can make use of it, from Alexei Starovoitov. 2) SFC driver supports busy polling, from Alexandre Rames. 3) Take advantage of hash table in UDP multicast delivery, from David Held. 4) Lighten locking, in particular by getting rid of the LRU lists, in inet frag handling. From Florian Westphal. 5) Add support for various RFC6458 control messages in SCTP, from Geir Ola Vaagland. 6) Allow to filter bridge forwarding database dumps by device, from Jamal Hadi Salim. 7) virtio-net also now supports busy polling, from Jason Wang. 8) Some low level optimization tweaks in pktgen from Jesper Dangaard Brouer. 9) Add support for ipv6 address generation modes, so that userland can have some input into the process. From Jiri Pirko. 10) Consolidate common TCP connection request code in ipv4 and ipv6, from Octavian Purdila. 11) New ARP packet logger in netfilter, from Pablo Neira Ayuso. 12) Generic resizable RCU hash table, with intial users in netlink and nftables. From Thomas Graf. 13) Maintain a name assignment type so that userspace can see where a network device name came from (enumerated by kernel, assigned explicitly by userspace, etc.) From Tom Gundersen. 14) Automatic flow label generation on transmit in ipv6, from Tom Herbert. 15) New packet timestamping facilities from Willem de Bruijn, meant to assist in measuring latencies going into/out-of the packet scheduler, latency from TCP data transmission to ACK, etc" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1536 commits) cxgb4 : Disable recursive mailbox commands when enabling vi net: reduce USB network driver config options. tg3: Modify tg3_tso_bug() to handle multiple TX rings amd-xgbe: Perform phy connect/disconnect at dev open/stop amd-xgbe: Use dma_set_mask_and_coherent to set DMA mask net: sun4i-emac: fix memory leak on bad packet sctp: fix possible seqlock seadlock in sctp_packet_transmit() Revert "net: phy: Set the driver when registering an MDIO bus device" cxgb4vf: Turn off SGE RX/TX Callback Timers and interrupts in PCI shutdown routine team: Simplify return path of team_newlink bridge: Update outdated comment on promiscuous mode net-timestamp: ACK timestamp for bytestreams net-timestamp: TCP timestamping net-timestamp: SCHED timestamp on entering packet scheduler net-timestamp: add key to disambiguate concurrent datagrams net-timestamp: move timestamp flags out of sk_flags net-timestamp: extend SCM_TIMESTAMPING ancillary data struct cxgb4i : Move stray CPL definitions to cxgb4 driver tcp: reduce spurious retransmits due to transient SACK reneging qlcnic: Initialize dcbnl_ops before register_netdev ...

mlx5: Adjust events to use unsigned long param instead of void *

2014-07-30T21:00:06Z

In the event flow, we currently pass only a port number in the void *data argument. Rather than pass a pointer to the event handlers, we should use an "unsigned long" parameter, and pass the port number value directly. In the future, if necessary for some events, we can use the unsigned long parameter to pass a pointer.

mlx5: minor fixes (mainly avoidance of hidden casts)

2014-07-30T21:00:06Z

There were many places where parameters which should be u8/u16 were integer type. Additionally, in 2 places, a check for a non-null pointer was added before dereferencing the pointer (this is actually a bug fix).

mlx5: Move pci device handling from mlx5_ib to mlx5_core

2014-07-30T21:00:06Z

In preparation for a new mlx5 device which is VPI (i.e., ports can be either IB or ETH), move the pci device functionality from mlx5_ib to mlx5_core. This involves the following changes: 1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev is now an independent structure maintained by mlx5_core. mlx5_ib_dev now has a pointer to that struct. This requires changing a lot of places where the core_dev struct was accessed via mlx5_ib_dev (now, this needs to be a pointer dereference). 2. All PCI initializations are now done in mlx5_core. Thus, it is now mlx5_core which does pci_register_device (and not mlx5_ib, as was previously). 3. mlx5_ib now registers itself with mlx5_core as an "interface" driver. This is very similar to the mechanism employed for the mlx4 (ConnectX) driver. Once the HCA is initialized (by mlx5_core), it invokes the interface drivers to do their initializations. 4. There is a new event handler which the core registers: mlx5_core_event(). This event handler invokes the event handlers registered by the interfaces.

net: mlx5: Use ktime_get_ns()

2014-07-23T22:01:43Z

This code is beyond silly: struct timespec ts = ktime_get_ts(); ktime_t ktime = timespec_to_ktime(ts); Further down the code builds the delta of two ktime_t values and converts the result to nanoseconds. Use ktime_get_ns() and replace all the nonsense. Signed-off-by: Thomas Gleixner Cc: Eli Cohen Signed-off-by: John Stultz

mlx5_core: Store MR attributes in mlx5_mr_core during creation and after UMR

2014-05-27T18:53:06Z

The patch stores iova, pd and size during mr creation and after UMRs that modify them. It removes the unused access flags field. Signed-off-by: Haggai Eran Signed-off-by: Roland Dreier

IB/mlx5: Collect signature error completion

2014-03-07T19:40:04Z

This commit takes care of the generated signature error CQE generated by the HW (if happened). The underlying mlx5 driver will handle signature error completions and will mark the relevant memory region as dirty. Once the consumer gets the completion for the transaction, it must check for signature errors on signature memory region using a new lightweight verb ib_check_mr_status(). In case the user doesn't check for signature error (i.e. doesn't call ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the memory region cannot be used for another signature operation (REG_SIG_MR work request will fail).

IB/mlx5: Keep mlx5 MRs in a radix tree under device

2014-03-07T19:26:49Z

This will be useful when processing signature errors on a specific key. The mlx5 driver will lookup the matching mlx5 memory region structure and mark it as dirty (contains signature errors). Signed-off-by: Sagi Grimberg Signed-off-by: Roland Dreier

mlx5: Implement create_mr and destroy_mr

2014-03-07T19:26:49Z

Support create_mr and destroy_mr verbs. Creating ib_mr may be done for either ib_mr that will register regular page lists like alloc_fast_reg_mr routine, or indirect ib_mrs that can register other (pre-registered) ib_mrs in an indirect manner. In addition user may request signature enable, that will mean that the created ib_mr may be attached with signature attributes (BSF, PSVs). Currently we only allow direct/indirect registration modes.

mlx5: Add include of because of kzalloc()/kfree() use

2014-02-14T04:48:02Z

On some architectures (for example, arm), we don't end up indirectly pulling in the declaration of kzalloc() and kfree(), and so building anything that includes breaks. Fix this by adding an explicit include to get the declaration. Reported-by: kbuild test robot Signed-off-by: Roland Dreier
