This extends bridge fdb table tracepoints to also cover learned fdb entries in the br_fdb_update path. Note that unlike other tracepoints I have moved this to when the fdb is modified because this is in the datapath and can generate a lot of noise in the trace output. br_fdb_update is also called from added_by_user context in the NTF_USE case which is already traced ..hence the !added_by_user check.

TC filters when used as classifiers are bound to TC classes. However, there is a hidden difference when adding them in different orders: 1. If we add tc classes before its filters, everything is fine. Logically, the classes exist before we specify their ID's in filters, it is easy to bind them together, just as in the current code base. 2. If we add tc filters before the tc classes they bind, we have to do dynamic lookup in fast path. What's worse, this happens all the time not just once, because on fast path tcf_result is passed on stack, there is no way to propagate back to the one in tc filters. This hidden difference hurts performance silently if we have many tc classes in hierarchy. This patch intends to close this gap by doing the reverse binding when we create a new class, in this case we can actually search all the filters in its parent, match and fixup by classid. And because tcf_result is specific to each type of tc filter, we have to introduce a new ops for each filter to tell how to bind the class. Note, we still can NOT totally get rid of those class lookup in ->enqueue() because cgroup and flow filters have no way to determine the classid at setup time, they still have to go through dynamic lookup.

Saeed Mahameed says: ==================== mlx5-updates-2017-08-31 (GRE Offloads support) This series provides the support for MPLS RSS and GRE TX offloads and RSS support. The first patch from Gal and Ariel provides the mlx5 driver support for ConnectX capability to perform IP version identification and matching in order to distinguish between IPv4 and IPv6 without the need to specify the encapsulation type, thus perform RSS in MPLS automatically without specifying MPLS ethertyoe. This patch will also serve for inner GRE IPv4/6 classification for inner GRE RSS. 2nd patch from Gal, Adds the TX offloads support for GRE tunneled packets, by reporting the needed netdev features. 3rd patch from Gal, Adds GRE inner RSS support by creating the needed device resources (Steering Tables/rules and traffic classifiers) to Match GRE traffic and perform RSS hashing on the inner headers.

Fix crash in linux PF driver when BARs have been cleared/de-programmed; fail early init (prior to mapping BARs) if the BAR0 or BAR1 registers are zero. This situation can arise when the PF is added to a VM (PCI pass-through), then a PF FLR is issued (in the VM). After this occurs, the BAR registers will be zero. If we attempt to load the PF driver in the host (after VM has been shutdown), the host can reset. Signed-off-by:

Introduce a new flow table and indirect TIRs which are used to hash the inner packet headers of GRE tunneled packets. When a GRE tunneled packet is received, the TTC flow table will match the new IPv4/6->GRE rules which will forward it to the inner TTC table. The inner TTC is similar to its counterpart outer TTC table, but matching the inner packet headers instead of the outer ones (and does not include the new IPv4/6->GRE rules). The new rules will not add steering hops since they are added to an already existing flow group which will be matched regardless of this patch. Non GRE traffic will not be affected. The inner flow table will forward the packet to inner indirect TIRs which hash the inner packet and thus result in RSS for the tunneled packets.

This change adds the ability for flow steering to classify IPv4/6 packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP packets and hit IPv4/6 classification steering rules. Since IP packets with MPLS tag header have MPLS ethertype, they missed the IPv4/6 ethertype rule and ended up hitting the default filter forwarding all the packets to the same single RQ (No RSS). Since our device is able to look past the MPLS tag and identify the next protocol we introduce this solution which replaces ethertype matching by the device's capability to perform IP version identification and matching in order to distinguish between IPv4 and IPv6. Therefore, when driver is performing flow steering configuration on the device it will use IP version matching in IP classified rules instead of ethertype matching which will cause relevant MPLS tagged packets to hit this rule as well. If the device doesn't support IP version matching the driver will fall back to use legacy ethertype matching in the steering as before. Signed-off-by:

IPv6 packet may carry more than one extension header, and IPv6 nodes must accept and attempt to process extension headers in any order and occurring any number of times in the same packet. Hence, there should be no assumption that Segment Routing extension header is to appear immediately after the IPv6 header. Moreover, section 4.1 of RFC 8200 gives a recommendation on the order of appearance of those extension headers within an IPv6 packet. According to this recommendation, Segment Routing extension header should appear after Hop-by-Hop and Destination Options headers (if they present). This patch fixes the get_srh(), so it gets the segment routing header regardless of its position in the chain of the extension headers in IPv6 packet, and makes sure that the IPv6 routing extension header is of Type 4.

Antoine Tenart says: ==================== net: mvpp2: comphy configuration This series, following up the one one the GoP/MAC configuration, aims at stopping to depend on the firmware/bootloader configuration when using the PPv2 engine. With this series the PPv2 driver does not need to rely on a previous configuration, and dynamic reconfiguration while the kernel is running can be done (i.e. switch one port from SGMII to 10G, or the opposite). A port can now be configured in a different mode than what's done in the firmware/bootloader as well. The series first contain patches in the generic PHY framework to support what is called the comphy (common PHYs), which is an h/w block providing PHYs that can be configured in various modes ranging from SGMII, 10G to SATA and others. As of now only the SGMII and 10G modes are supported by the comphy driver. Then patches are modifying the PPv2 driver to first add the comphy initialization sequence (i.e. calls to the generic PHY framework) and to then take advantage of this to allow dynamic reconfiguration (i.e. configuring the mode of a port given what's connected, between sgmii and 10G). Note the use of the comphy in the PPv2 driver is kept optional (i.e. if not described in dt the driver still as before an relies on the firmware/bootloader configuration). Finally there are dt/defconfig patches to describe and take advantage of this. This was tested on a range of devices: 8040-db, 8040-mcbin and 7040-db. @Dave: the dt patches should go through the mvebu tree (patches 9-13). Thanks! Antoine Since v3: - Now use of_phy_simple_xlate() to retrieve the phy. - Added an owner in the phy_ops structure. - Now allow the module to be selected with COMPILE_TEST. - Removed unused parameter in the comphy set_mode functions. - Added Kishon Acked-by in patch 1. Since v2: - Kept the link mode enforcement. - Removed the netif_running() check. - Reworded the "dynamic reconfiguration of the PHY mode" commit log. - Added one patch not to force the GMAC autoneg parameters when using the XLG MAC. Since v1: - Updated the mode settings variable name in the comphy driver to have 'cp110' in it. - Documented the PHY cell argument in the dt documentation. - New patch adding comphy phandles for the 7040-db board. - Checked if the carrier_on/off functions were needed. They are. - s/PHY/generic PHY/ in commit log of patch 1. - Rebased on the latest net-next/master. ==================== Signed-off-by:

This patch adds logic to reconfigure the comphy/GoP/MAC when the link state is updated at runtime. This is very useful on boards where many link speed are supported: depending on what is negotiated the PPv2 driver will automatically reconfigures the link between the PHY and the MAC. Signed-off-by:

On some platforms, the comphy is between the MAC GoP and the PHYs. The mvpp2 driver currently relies on the firmware/bootloader to configure the comphy. As a comphy driver was added to the generic PHY framework, this patch uses it in the mvpp2 driver to configure the comphy at boot time to avoid relying on the bootloader. Signed-off-by:

Antoine Tenart authored
On the CP110 unit, which can be found on various Marvell platforms such as the 7k and 8k (currently), a comphy (common PHYs) hardware block can be found. This block provides a number of PHYs which can be used in various modes by other controllers (network, SATA ...). These common PHYs must be configured for the controllers using them to work correctly either at boot time, or when the system runs to switch the mode used. This patch adds a driver for this comphy hardware block, providing callbacks for the its PHYs so that consumers can configure the modes used. As of this commit, two modes are supported by the comphy driver: sgmii and 10gkr. Signed-off-by:

Chris Mi says: ==================== net/sched: Improve getting objects by indexes Using current TC code, it is very slow to insert a lot of rules. In order to improve the rules update rate in TC, we introduced the following two changes: 1) changed cls_flower to use IDR to manage the filters. 2) changed all act_xxx modules to use IDR instead of a small hash table But IDR has a limitation that it uses int. TC handle uses u32. To make sure there is no regression, we add several new IDR APIs to support unsigned long. v2 == Addressed Hannes's comment: express idr_alloc in terms of idr_alloc_ext and most of the other functions ==================== Signed-off-by:

Typically, each TC filter has its own action. All the actions of the same type are saved in its hash table. But the hash buckets are too small that it degrades to a list. And the performance is greatly affected. For example, it takes about 0m11.914s to insert 64K rules. If we convert the hash table to IDR, it only takes about 0m1.500s. The improvement is huge. But please note that the test result is based on previous patch that cls_flower uses IDR. Signed-off-by:

Currently, all filters with the same priority are linked in a doubly linked list. Every filter should have a unique handle. To make the handle unique, we need to iterate the list every time to see if the handle exists or not when inserting a new filter. It is time-consuming. For example, it takes about 5m3.169s to insert 64K rules. This patch changes cls_flower to use IDR. With this patch, it takes about 0m1.127s to insert 64K rules. The improvement is huge. But please note that in this testing, all filters share the same action. If every filter has a unique action, that is another bottleneck. Follow-up patch in this patchset addresses that.

The data from hardware follows the multiplexing and aggregation protocol (MAP). This driver can be used to register onto any physical network device in IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator. rmnet driver helps to decode these packets and queue them to network stack (and encode and transmit it to the physical device). v1: Same as the RFC patch with some minor fixes for issues reported by kbuild test robot. v1->v2: Change datatypes and remove config IOCTL as mentioned by David. Also fix checkpatch issues and remove some unused code. v2->v3: Move location to drivers/net and rename to rmnet. Change the userspace - netlink communication from custom netlink to rtnl_link_ops. Refactor some code. Use a fixed config for ingress and egress. v3->v4: Move location to drivers/net/ethernet/qualcomm/. Fix comments from Stephen and Jiri - Split the ether and arp type changes into seperate patches. Remove debug and custom logging and switch to standard netdevice log. Remove module parameters. Refactor and change some code style issues. v4->v5: Rename some structs and variables. Move the initializer before the for loop start. Put the arp type in correct sequence. v5->v6: Fix comments from Dan - Use the upper link API. As a result, remove all the refcounting logic. Device refcount is explicitly held on real_dev on rx_handler registration only. Modifiy the flow control struct. Remove the unused ethernet mode handling. v6->v7: Fix comments from David - Add newline to end of Makefile. Remove inline from .c files. Move the module init/exit to rmnet config. Fix an error reported by kbuild test robot for an unused file. v7->v8: Use a smaller value for ETH_P_MAP as mentioned by David. Change netdev_info to netdev_dbg as mentioned by Andew. Fix comments from Stephen regarding netdev_priv and sparse related errors of using 0 as NULL v8->v9: Fix comments from David - Remove the CFLAG rule. Change the way rmnet devices are freed. Instead of using a workqueue to unregister devices individually, go through the list and free all devices within the rtnl_lock(). v9->v10: Actually fix the locking as mentioned by David.

Florian reported UDP xmit drops that could be root caused to the too small neigh limit. Current limit is 64 KB, meaning that even a single UDP socket would hit it, since its default sk_sndbuf comes from net.core.wmem_default (~212992 bytes on 64bit arches). Once ARP/ND resolution is in progress, we should allow a little more packets to be queued, at least for one producer. Once neigh arp_queue is filled, a rogue socket should hit its sk_sndbuf limit and either block in sendmsg() or return -EAGAIN. Signed-off-by:
