Primary use case is a histogram array of latency where bpf program computes the latency of block requests or other events and stores histogram of latency into array of 64 elements. All cpus are constantly running, so normal increment is not accurate, bpf_xadd causes cache ping-pong and this per-cpu approach allows fastest collision-free counters. Signed-off-by:

Introduce BPF_MAP_TYPE_PERCPU_HASH map type which is used to do accurate counters without need to use BPF_XADD instruction which turned out to be too costly for high-performance network monitoring. In the typical use case the 'key' is the flow tuple or other long living object that sees a lot of events per second. bpf_map_lookup_elem() returns per-cpu area. Example: struct { u32 packets; u32 bytes; } * ptr = bpf_map_lookup_elem(&map, &key); /* ptr points to this_cpu area of the value, so the following * increments will not collide with other cpus */ ptr->packets ++; ptr->bytes += skb->len; bpf_update_elem() atomically creates a new element where all per-cpu values are zero initialized and this_cpu value is populated with given 'value'. Note that non-per-cpu hash map always allocates new element and then deletes old after rcu grace period to maintain atomicity of update. Per-cpu hash map updates element values in-place.

If we remove the SYN flag from the skbs that tcp_fastopen_add_skb() places in socket receive queue, then we can remove the test that tcp_recvmsg() has to perform in fast path. All we have to do is to adjust SEQ in the slow path. For the moment, we place an unlikely() and output a message if we find an skb having SYN flag set. Goal would be to get rid of the test completely. Signed-off-by:

RFC 7413 (TCP Fast Open) 4.2.2 states that the SYNACK message MAY include data and/or FIN This patch adds support for the client side : If we receive a SYNACK with payload or FIN, queue the skb instead of ignoring it. Since we already support the same for SYN, we refactor the existing code and reuse it. Note we need to clone the skb, so this operation might fail under memory pressure. Sara Dickinson pointed out FreeBSD server Fast Open implementation was planned to generate such SYNACK in the future. The server side might be implemented on linux later. Reported-by:

Jarod Wilson says: ==================== net: add and use rx_nohandler stat counter The network core tries to keep track of dropped packets, but some packets you wouldn't really call dropped, so much as intentionally ignored, under certain circumstances. One such case is that of bonding and team device slaves that are currently inactive. Their respective rx_handler functions return RX_HANDLER_EXACT (the only places in the kernel that return that), which ends up tracking into the network core's __netif_receive_skb_core() function's drop path, with no pt_prev set. On a noisy network, this can result in a very rapidly incrementing rx_dropped counter, not only on the inactive slave(s), but also on the master device, such as the following: $ cat /proc/net/dev Inter-| Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed p7p1: 14783346 140430 0 140428 0 0 0 2040 680 8 0 0 0 0 0 0 p7p2: 14805198 140648 0 0 0 0 0 2034 0 0 0 0 0 0 0 0 bond0: 53365248 532798 0 421160 0 0 0 115151 2040 24 0 0 0 0 0 0 lo: 5420 54 0 0 0 0 0 0 5420 54 0 0 0 0 0 0 p5p1: 19292195 196197 0 140368 0 0 0 56564 680 8 0 0 0 0 0 0 p5p2: 19289707 196171 0 140364 0 0 0 56547 680 8 0 0 0 0 0 0 em3: 20996626 158214 0 0 0 0 0 383 0 0 0 0 0 0 0 0 em2: 14065122 138462 0 0 0 0 0 310 0 0 0 0 0 0 0 0 em1: 14063162 138440 0 0 0 0 0 308 0 0 0 0 0 0 0 0 em4: 21050830 158729 0 0 0 0 0 385 71662 469 0 0 0 0 0 0 ib0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 In this scenario, p5p1, p5p2 and p7p1 are all inactive slaves in an active-backup bond0, and you can see that all three have high drop counts, with the master bond0 showing a tally of all three. I know that this was previously discussed some here: http://www.spinics.net/lists/netdev/msg226341.html It seems additional counters never came to fruition, so this is a first attempt at creating one of them, so that we stop calling these drops, which for users monitoring rx_dropped, causes great alarm, and renders the counter much less useful for them. This adds a sysfs statistics node and makes the counter available via netlink. Additionally, I'm not certain if this set qualifies for net, or if it should be put aside and resubmitted for net-next after 4.5 is put to bed, but I do have users who consider this an important bugfix. This has been tested quite a bit on x86_64, and now lightly on i686 as well, to verify functionality of updates to netdev_stats_to_stats64() on 32-bit arches. ==================== Signed-off-by:

The netdev_stats_to_stats64 function copies the deprecated net_device_stats format stats into rtnl_link_stats64 for legacy support purposes, but with the BUILD_BUG_ON as it was, it wasn't possible to extend rtnl_link_stats64 without also extending net_device_stats. Relax the BUILD_BUG_ON to only require that rtnl_link_stats64 is larger, and zero out all the stat counters that aren't present in net_device_stats.

Richard Alpe authored
Changing certain link attributes (link tolerance and link priority) from the TIPC management tool is supposed to automatically take effect at both endpoints of the affected link. Currently the media address is not instantiated for the link and is used uninstantiated when crafting protocol messages designated for the peer endpoint. This means that changing a link property currently results in the property being changed on the local machine but the protocol message designated for the peer gets lost. Resulting in property discrepancy between the endpoints. In this patch we resolve this by using the media address from the link entry and using the bearer transmit function to send it. Hence, we can now eliminate the redundant function tipc_link_prot_xmit() and the redundant field tipc_link::media_addr. Fixes: 2af5ae37 (tipc: clean up unused code and structures) Reviewed-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-03 This series contains updates to i40e and i40evf only. Kiran adds the MAC filter element to the end of the list instead of HEAD just in case there are ever any ordering issues in the future. Anjali fixes several RSS issues, first fixes the hash PCTYPE enable for X722 since it supports a broader selection of PCTYPES for TCP and UDP. Then fixes a bug in XL710, X710, and X722 support for RSS since we cannot reduce the 4-tuple for RSS for TCP/IPv4/IPv6 or UDP/IPv4/IPv6 packets since this requires a product feature change coming in a later release. Cleans up the reset code where the restart-autoneg workaround is applied, since X722 does not need the workaround, add a flag to indicate which MAC and firmware version require the workaround to be applied. Adds new device id's for X722 and code to add their support. Also adds another way to access the RSS keys and lookup table using the admin queue for X722 devices. Catherine updates the driver to replace the MAC check with a feature flag check for 100M SGMII, since it is only support on X722 devices currently. Mitch reworks the VF driver to allow channel bonding, which was not possible before this patch due to the asynchronous nature of the admin queue mechanism. Also fixes a rare case which causes a panic if the VF driver is removed during reset recovery, resolve this by setting the ring pointers to NULL after freeing them. Shannon cleans up the driver where device capabilities were defined in two different places, and neither had all the definitions, so he consolidates the definitions in the admin queue API. Also adds the new proxy-wake-on-lan capability bit available with the new X722 device. Lastly, added the new External Device Power Ability field to the get_link_status data structure by using a reserved field at the end of the structure. Jesse mimics the ixgbe driver's use of a private work queue in the i40e and i40evf drivers to avoid blocking the system work queue. Greg cleans up the driver to limit the firmware revision checks to properly handle DCB configurations from the firmware to the older devices which need these checks (specifically X710 and XL710 devices only). ==================== Signed-off-by:

When we create IPvlan slave; we use ether_setup() and that sets up default MTU to 1500 while the master device may have lower / different MTU. Any subsequent changes to the masters' MTU are reflected into the slaves' MTU setting. However if those don't happen (most likely scenario), the slaves' MTU stays at 1500 which could be bad. This change adds code to inherit MTU from the master device instead of using the default value during the link initialization phase. Signed-off-by:

In some modes, bonding would not enslave VF interfaces. This is due to bonding calling change_mtu and the immediately calling open. Because of the asynchronous nature of the admin queue mechanism, the VF returns -EBUSY to the open call, because it knows the previous operation hasn't finished yet. This causes bonding to fail with a less-than-useful error message. To fix this, remove the check for pending operations at the beginning of open. But this introduces a new bug where the driver will panic on a quick close/open cycle. To fix that, we add a new driver state, __I40EVF_DOWN_PENDING, that the driver enters when down is called. The driver finally transitions to a fully DOWN state when it receives confirmation from the PF driver that all the queues are disabled. This allows open to complete even if there is a pending mtu change, and bonding is finally happy. Change-ID: I06f4c7e435d5bacbfceaa7c3f209e0ff04be21cc Signed-off-by:

Pull libnvdimm fixes from Dan Williams: "1/ Fixes to the libnvdimm 'pfn' device that establishes a reserved area for storing a struct page array. 2/ Fixes for dax operations on a raw block device to prevent pagecache collisions with dax mappings. 3/ A fix for pfn_t usage in vm_insert_mixed that lead to a null pointer de-reference. These have received build success notification from the kbuild robot across 153 configs and pass the latest ndctl tests" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: phys_to_pfn_t: use phys_addr_t mm: fix pfn_t to page conversion in vm_insert_mixed block: use DAX for partition table reads block: revert runtime dax control of the raw block device fs, block: force direct-I/O for dax-enabled block devices devm_memremap_pages: fix vmem_altmap lifetime + alignment handling libnvdimm, pfn: fix restoring memmap location libnvdimm: fix mode determination for e820 devices
