Cong Wang says: ==================== fou: some fixes and updates Patch 1~3 fix some minor bugs in net/ipv4/fou.c, the only thing I am not sure is if it's too late to change the byte order of FOU_ATTR_PORT, if so we have to fix iproute2 instead of kernel. Patch 4~5 add some new features to make it complete. v2: make fou->port be16 too ==================== Acked-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>

With recent adoption of skc_cookie in struct sock_common, struct tcp_timewait_sock size increased from 192 to 200 bytes on 64bit arches. SLAB rounds then to 256 bytes. It is time to drop SLAB_HWCACHE_ALIGN constraint for twsk_slab. This saves about 12 MB of memory on typical configuration reaching 262144 timewait sockets, and has no noticeable impact on performance.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-10 This series contains updates to ixgbe and documentation for igb, ixgbe and ixgb. Stephen cleans up documentation to igb, ixgbe and ixgb. Don updates how bridge mode is stored to minimize obfuscation and makes updates for future silicon easier. Adds a new bridge mode support function which gathers all the logic needed to configure bridge modes. Adds Source Address Prunning for VEPA bridge mode for x550 devices. Vasu adds specific FCoE offloads for x550 for DDP context programming and increased DDP exchanges. Alex Duyck cleans up the use of HW_VLAN_CTAG_FILTER in hw_features, where the driver was actually ignoring the value of the bit and was just assuming it was always set. Also cleans up the use of rcu_barrier() since the driver has not used call_rcu() to free the rings for some time now. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This change makes it so that the HW_VLAN_CTAG_FILTER bit is not falsely advertised as being a feature that can be toggled on ixgbe parts. The driver was setting the bit in features and letting it be inherited by hw_features, however the driver was actually ignoring the value of the bit and just assuming it was always set. As a result VLAN filtering was always enabled which is a requirement for SR-IOV, VMDq, DCB, FCoE, and possibly other features within the adapters.

Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next Johan Hedberg says: ==================== pull request: bluetooth-next 2015-04-09 We've had enough new patches during the past week (especially from Marcel) that it'd be good to still get these queued for 4.1. The majority of the changes are from Marcel with lots of cleanup & refactoring patches for the HCI UART driver. Marcel also split out some Broadcom & Intel vendor specific functionality into two new btintel & btbcm modules. In addition to the HCI driver changes there's the completion of our local OOB data interface for pairing, added support for requesting remote LE features when connecting, as well as a couple of minor fixes for mac802154. Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Currently a call to configure the Rx mode (promiscuous mode, all multicast mode, etc.) is made in xgbe_start separate from the xgbe_init function.

Currently the device must be down in order to update the rx-frames coalescing setting because the interrupt indicator is set in the descriptor data during initialization. Allow this setting to be changed while the device is up by moving the interrupt decision into the descriptor reset function and base the decision off of the supplied descriptor index value.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree. They are: * nf_tables set timeout infrastructure from Patrick Mchardy. 1) Add support for set timeout support. 2) Add support for set element timeouts using the new set extension infrastructure. 4) Add garbage collection helper functions to get rid of stale elements. Elements are accumulated in a batch that are asynchronously released via RCU when the batch is full. 5) Add garbage collection synchronization helpers. This introduces a new element busy bit to address concurrent access from the netlink API and the garbage collector. 5) Add timeout support for the nft_hash set implementation. The garbage collector peridically checks for stale elements from the workqueue. * iptables/nftables cgroup fixes: 6) Ignore non full-socket objects from the input path, otherwise cgroup match may crash, from Daniel Borkmann. 7) Fix cgroup in nf_tables. 8) Save some cycles from xt_socket by skipping packet header parsing when skb->sk is already set because of early demux. Also from Daniel. * br_netfilter updates from Florian Westphal. 9) Save frag_max_size and restore it from the forward path too. 10) Use a per-cpu area to restore the original source MAC address when traffic is DNAT'ed. 11) Add helper functions to access physical devices. 12) Use these new physdev helper function from xt_physdev. 13) Add another nf_bridge_info_get() helper function to fetch the br_netfilter state information. 14) Annotate original layer 2 protocol number in nf_bridge info, instead of using kludgy flags. 15) Also annotate the pkttype mangling when the packet travels back and forth from the IP to the bridge layer, instead of using a flag. * More nf_tables set enhancement from Patrick: 16) Fix possible usage of set variant that doesn't support timeouts. 17) Avoid spurious "set is full" errors from Netlink API when there are pending stale elements scheduled to be released. 18) Restrict loop checks to set maps. 19) Add support for dynamic set updates from the packet path. 20) Add support to store optional user data (eg. comments) per set element. BTW, I have also pulled net-next into nf-next to anticipate the conflict resolution between your okfn() signature changes and Florian's br_netfilter updates. ==================== Signed-off-by: David S.

Alexander Duyck says: ==================== Replace wmb()/rmb() with dma_wmb()/dma_rmb() where appropriate, round 2 More cleanup of drivers in order to start making use of dma_rmb and dma_wmb calls. This is another pass of what I would consider to be low hanging fruit. There may be other opportunities to make use of the barriers in the Mellanox and Chelsio drivers but I didn't want to risk meddling with code I was not completely familiar with so I am leaving that for future work. I have revisited the Mellanox driver changes. This time around I went only for the sections with a clearly defined pattern. For dma_wmb I used it between accesses of the descriptor bits followed by owner or size. For dma_rmb I used it to replace rmb following a read of the ownership bit in the descriptor. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This patch should help to improve the performance of the mlx4 and mlx5 on a number of architectures. For example, on x86 the dma_wmb/rmb equates out to a barrer() call as the architecture is already strong ordered, and on PowerPC the call works out to a lwsync which is significantly less expensive than the sync call that was being used for wmb. I placed the new barriers between any spots that seemed to be trying to order memory/memory reads or writes, if there are any spots that involved MMIO I left the existing wmb in place as the new barriers cannot order transactions between coherent and non-coherent memories. v2: Reduced the replacments to just the spots where I could clearly identify the usage pattern.
