The same code which recognizes ICMP error packets is duplicated several times. Use the icmp_is_err() and icmpv6_is_err() helpers instead, which do the same thing. ip_multipath_l3_keys() and tcf_nat_act() didn't check for all the error types, assume that they should instead. Signed-off-by:

Add two helper functions, one for IPv4 and one for IPv6, to recognize the ICMP packets which are error responses. This packets are special because they have as payload the original header of the packet which generated it (RFC 792 says at least 8 bytes, but Linux actually includes much more than that).

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-11-04 This series contains updates to the ice driver only. Anirudh refactors the code to reduce the kernel configuration flags and introduces ice_base.c file. Maciej does additional refactoring on the configuring of transmit rings so that we are not configuring per each traffic class flow. Added support for XDP in the ice driver. Provides additional re-organizing of the code in preparation for adding build_skb() support in the driver. Adjusted the computational padding logic for headroom and tailroom to better support build_skb(), which also aligns with the logic in other Intel LAN drivers. Added build_skb support and make use of the XDP's data_meta. Krzysztof refactors the driver to prepare for AF_XDP support in the driver and then adds support for AF_XDP. v2: Updated patch 3 of the series based on community feedback with the following changes... - return -EOPNOTSUPP instead of ENOTSUPP for too large MTU which makes it impossible to attach XDP prog - don't check for case when there's no XDP prog currently on interface and ice_xdp() is called with NULL bpf_prog; this happens when user does "ip link set eth0 xdp off" and no prog is present on VSI; no need for that as it is handled by higher layer - drop the extack message for unknown xdp->command - use the smp_processor_id() for accessing the XDP Tx ring for XDP_TX action - don't leave the interface in downed state in case of any failure during the XDP Tx resources handling - undo rename of ice_build_ctob The above changes caused a ripple effect in patches 4 & 5 to update references to ice_build_ctob() which are now build_ctob() ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2019-11-04 This series contains old Halloween candy updates, yet still sweet, to fm10k, ixgbe and i40e. Jake adds the missing initializers for a couple of the TLV attribute macros. Added support for capturing and reporting statistics for all of the VFs in a given PF. Lastly, bump the version of the fm10k driver to reflect the recent changes. Alex addresses locality issues in the ixgbe driver when it is loaded on a system supporting multiple NUMA nodes. Manjunath Patil provides changes to the ixgbe driver, similar to those made to igb, to prevent transmit packets to request a hardware timestamp when the NIC has not been setup via the SIOCSHWTSTAMP ioctl. Alice adds support for x710 by adding the missing device id's in the appropriate places to ensure all the features are enabled in i40e. Jesse adds support for VF stats gathering in the i40e via the kernel via ndo_get_vf_stats function. v2: Fixed up commit id references in patch 5's description to align with how commit id's should be referenced. ==================== Signed-off-by:

HW timestamping can only be requested for a packet if the NIC is first setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the ixgbe driver still allowed TX packets to request HW timestamping. In this situation, we see 'clearing Tx Timestamp hang' noise in the log. Fix this by checking that the NIC is configured for HW TX timestamping before accepting a HW TX timestamping request.

This patch is meant to address locality issues present in the ixgbe driver when it is loaded on a system supporting multiple NUMA nodes and more CPUs then the device can map in a 1:1 fashion. Instead of just arbitrarily mapping itself to CPUs 0-62 it would make much more sense to map itself to the local CPUs first, and then map itself to any remaining CPUs that might be used. The first effect of this is that queue 0 should always be allocated on the local CPU/NUMA node. This is important as it is the default destination if a packet doesn't match any existing flow director filter or RSS rule and as such having it local should help to reduce QPI cross-talk in the event of an unrecognized traffic type. In addition this should increase the likelihood of the RSS queues being allocated and used on CPUs local to the device while the ATR/Flow Director queues would be able to route traffic directly to the CPU that is likely to be processing it.

Driver is now prepared for building the skb around the existing Rx buffer, so introduce the ice_build_skb responsible for it. Make use of XDP's data_meta as well. I've observed around 30% less CPU consumption with build_skb Rx path, in comparison to legacy Rx. What stands behind such result is the avoidance of flow_dissector (which we were diving into via eth_get_headlen) and no memcpy calls. Signed-off-by:

Take into account the underlying architecture specific settings and based on that calculate the possible padding that can be supplied. Typically, for x86 and standard MTU size we will end up with 192 bytes of headroom. This is the same behavior as our other drivers have and we can dedicate it for XDP purposes. Furthermore, introduce the Rx ring flag for indicating whether build_skb is used on particular. Based on that invoke the routines for padding calculation. Signed-off-by:

Add an ethtool "legacy-rx" priv flag for toggling the Rx path. This control knob will be mainly used for build_skb usage as well as buffer size/MTU manipulation. In preparation for adding build_skb support in a way that it takes care of how we set the values of max_frame and rx_buf_len fields of struct ice_vsi. Specifically, in this patch mentioned fields are set to values that will allow us to provide headroom and tailroom in-place. This can be mostly broken down onto following: - for legacy-rx "on" ethtool control knob, old behaviour is kept; - for standard 1500 MTU size configure the buffer of size 1536, as network stack is expecting the NET_SKB_PAD to be provided and NET_IP_ALIGN can have a non-zero value (these can be typically equal to 32 and 2, respectively); - for larger MTUs go with max_frame set to 9k and configure the 3k buffer in case when PAGE_SIZE of underlying arch is less than 8k; 3k buffer is implying the need for order 1 page, so that our page recycling scheme can still be applied; With that said, substitute the hardcoded ICE_RXBUF_2048 and PAGE_SIZE values in DMA API that we're making use of with rx_ring->rx_buf_len and ice_rx_pg_size(rx_ring). The latter is an introduced helper for determining the page size based on its order (which was figured out via ice_rx_pg_order). Last but not least, take care of truesize calculation. In the followup patch the headroom/tailroom computation logic will be introduced. This change aligns the buffer and frame configuration with other Intel drivers, most importantly with iavf.

Add zero copy AF_XDP support. This patch adds zero copy support for Tx and Rx; code for zero copy is added to ice_xsk.h and ice_xsk.c. For Tx, implement ndo_xsk_wakeup. As with other drivers, reuse existing XDP Tx queues for this task, since XDP_REDIRECT guarantees mutual exclusion between different NAPI contexts based on CPU ID. In turn, a netdev can XDP_REDIRECT to another netdev with a different NAPI context, since the operation is bound to a specific core and each core has its own hardware ring. For Rx, allocate frames as MEM_TYPE_ZERO_COPY on queues that AF_XDP is enabled. Signed-off-by:

Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error.

When commit df1c0b84 ("[BRIDGE]: Packets leaking out of disabled/blocked ports.") introduced the port state tests in br_fdb_update() it was to avoid learning/refreshing from STP BPDUs, it was also used to avoid learning/refreshing from user-space with NTF_USE. Those two tests are done for every packet entering the bridge if it's learning, but for the fast-path we already have them checked in br_handle_frame() and is unnecessary to do it again. Thus push the checks to the unlikely cases and drop them from br_fdb_update(), the new nbp_state_should_learn() helper is used to determine if the port state allows br_fdb_update() to be called. The two places which need to do it manually are: - user-space add call with NTF_USE set - link-local packet learning done in __br_handle_local_finish() Signed-off-by:
