This patch adds hardware offload support for nftables through the existing netdev_ops->ndo_setup_tc() interface, the TC_SETUP_CLSFLOWER classifier and the flow rule API. This hardware offload support is available for the NFPROTO_NETDEV family and the ingress hook. Each nftables expression has a new ->offload interface, that is used to populate the flow rule object that is attached to the transaction object. There is a new per-table NFT_TABLE_F_HW flag, that is set on to offload an entire table, including all of its chains. This patch supports for basic metadata (layer 3 and 4 protocol numbers), 5-tuple payload matching and the accept/drop actions; this also includes basechain hardware offload only. Signed-off-by:

This patch completes the flow block API to introduce: * flow_block_cb_priv() to access callback private data. * flow_block_cb_incref() to bump reference counter on this flow block. * flow_block_cb_decref() to decrement the reference counter. These functions are taken from the existing tcf_block_cb_priv(), tcf_block_cb_incref() and tcf_block_cb_decref(). Signed-off-by:

This patch adds the list handling functions for the flow block API: * flow_block_cb_lookup() allows drivers to look up for existing flow blocks. * flow_block_cb_add() adds a flow block to the per driver list to be registered by the core. * flow_block_cb_remove() to remove a flow block from the list of existing flow blocks per driver and to request the core to unregister this. The flow block API also annotates the netns this flow block belongs to. Signed-off-by:

Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API. Signed-off-by:

Jiangfeng Xiao says: ==================== net: hisilicon: Add support for HI13X1 to hip04_eth The main purpose of this patch series is to extend the hip04_eth driver to support HI13X1_GMAC. The offset and bitmap of some registers of HI13X1_GMAC are different from hip04_eth common soc. In addition, the definition of send descriptor and parsing descriptor are different from hip04_eth common soc. So the macro of the register offset is redefined to adapt the HI13X1_GMAC. Clean up the sparse warning by the way. Change since v1: * Add a cover letter. ==================== Signed-off-by: -

The buf unit size of HI13X1_GMAC is cache_line_size, which is 64, so the address we write to the buf register needs to be shifted right by 6 bits. The 31st bit of the PPE_CFG_CPU_ADD_ADDR register of HI13X1_GMAC indicates whether to release the buffer of the message, and the low indicates that it is valid. Signed-off-by:

Lucas Bates says: ==================== tc-testing: Add plugin for simple traffic generation This series supersedes the previous submission that included a patch for test case verification using JSON output. It adds a new tdc plugin, scapyPlugin, as a way to send traffic to test tc filters and actions. The first patch makes a change to the TdcPlugin module that will allow tdc plugins to examine the test case currently being executed, so plugins can play a more active role in testing by accepting information or commands from the test case. This is required for scapyPlugin to work. The second patch adds scapyPlugin itself, and an example test case file to demonstrate how the scapy block works in the test cases. ==================== Signed-off-by: -
Lucas Bates authored
The scapyPlugin allows for simple traffic generation in tdc to test various tc features. It was tested with scapy v2.4.2, but should work with any successive version. In order to use the plugin's functionality, scapy must be installed. This can be done with: pip3 install scapy or to install 2.4.2: pip3 install scapy==2.4.2 If the plugin is unable to import the scapy module, it will terminate the tdc run. The plugin makes use of a new key in the test case data, 'scapy'. This block contains three other elements: 'iface', 'count', and 'packet': "scapy": { "iface": "$DEV0", "count": 1, "packet": "Ether(type=0x800)/IP(src='16.61.16.61')/ICMP()" }, * iface is the name of the device on the host machine from which the packet(s) will be sent. Values contained within tdc_config.py's NAMES dict can be used here - this is useful if paired with nsPlugin * count is the number of copies of this packet to be sent * packet is a string detailing the different layers of the packet to be sent. If a property isn't explicitly set, scapy will set default values for you. Layers in the packet info are separated by slashes. For info about common TCP and IP properties, see: https://blogs.sans.org/pen-testing/files/2016/04/ScapyCheatSheet_v0.2.pdf Caution is advised when running tests using the scapy functionality, since the plugin blindly sends the packet as defined in the test case data. See creating-testcases/scapy-example.json for sample test cases; the first test is intended to pass while the second is intended to fail.

Instead of only passing the test case name and ID, pass the entire current test case down to the plugins. This change allows plugins to start accepting commands and directives from the test cases themselves, for greater flexibility in testing. Signed-off-by:

Josua Mayer says: ==================== Fix hang of Armada 8040 SoC in orion-mdio With a modular kernel as configured by Debian a hang was observed with the Armada 8040 SoC in the Clearfog GT and Macchiatobin boards. The 8040 SoC actually requires four clocks to be enabled for the mdio interface to function. All 4 clocks are already specified in armada-cp110.dtsi. It has however been missed that the orion-mdio driver only supports enabling up to three clocks. This patch-set allows the orion-mdio driver to handle four clocks and adds a warning when more clocks are specified to prevent this particular oversight in the future. Changes since v1: - fixed condition for priting the warning (Andrew Lunn) - rephrased commit description for deferred probing (Andrew Lunn) - fixed compiler warnings (kbuild test robot) ==================== Signed-off-by: -

Commit a993db88 ("net: stmmac: Enable support for > 32 Bits addressing in XGMAC"), introduced support for > 32 bits addressing in XGMAC but the conversion of descriptors to dma_addr_t was left out. As some devices assing coherent memory in regions > 32 bits we need to set lower and upper value of descriptors address when initializing DMA channels. Luckly, this was working for me because I was assigning CMA to < 4GB address space for performance reasons.
