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: -

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.

Paul Blakey says: ==================== net/sched: Introduce tc connection tracking This patch series add connection tracking capabilities in tc sw datapath. It does so via a new tc action, called act_ct, and new tc flower classifier matching on conntrack state, mark and label. Usage is as follows: $ tc qdisc add dev ens1f0_0 ingress $ tc qdisc add dev ens1f0_1 ingress $ tc filter add dev ens1f0_0 ingress \ prio 1 chain 0 proto ip \ flower ip_proto tcp ct_state -trk \ action ct zone 2 pipe \ action goto chain 2 $ tc filter add dev ens1f0_0 ingress \ prio 1 chain 2 proto ip \ flower ct_state +trk+new \ action ct zone 2 commit mark 0xbb nat src addr 5.5.5.7 pipe \ action mirred egress redirect dev ens1f0_1 $ tc filter add dev ens1f0_0 ingress \ prio 1 chain 2 proto ip \ flower ct_zone 2 ct_mark 0xbb ct_state +trk+est \ action ct nat pipe \ action mirred egress redirect dev ens1f0_1 $ tc filter add dev ens1f0_1 ingress \ prio 1 chain 0 proto ip \ flower ip_proto tcp ct_state -trk \ action ct zone 2 pipe \ action goto chain 1 $ tc filter add dev ens1f0_1 ingress \ prio 1 chain 1 proto ip \ flower ct_zone 2 ct_mark 0xbb ct_state +trk+est \ action ct nat pipe \ action mirred egress redirect dev ens1f0_0 The pattern used in the design here closely resembles OvS, as the plan is to also offload OvS conntrack rules to tc. OvS datapath rules uses it's recirculation mechanism to send specific packets to conntrack, and return with the new conntrack state (ct_state) on some other recirc_id to be matched again (we use goto chain for this). This results in the following OvS datapath rules: recirc_id(0),in_port(ens1f0_0),ct_state(-trk),... actions:ct(zone=2),recirc(2) recirc_id(2),in_port(ens1f0_0),ct_state(+new+trk),ct_mark(0xbb),... actions:ct(commit,zone=2,nat(src=5.5.5.7),mark=0xbb),ens1f0_1 recirc_id(2),in_port(ens1f0_0),ct_state(+est+trk),ct_mark(0xbb),... actions:ct(zone=2,nat),ens1f0_1 recirc_id(1),in_port(ens1f0_1),ct_state(-trk),... actions:ct(zone=2),recirc(1) recirc_id(1),in_port(ens1f0_1),ct_state(+est+trk),... actions:ct(zone=2,nat),ens1f0_0 Changelog: See individual patches. ==================== Signed-off-by: -

Allow sending a packet to conntrack module for connection tracking. The packet will be marked with conntrack connection's state, and any metadata such as conntrack mark and label. This state metadata can later be matched against with tc classifers, for example with the flower classifier as below. In addition to committing new connections the user can optionally specific a zone to track within, set a mark/label and configure nat with an address range and port range.

Jakub Kicinski says: ==================== nfp: tls: fixes for initial TLS support This series brings various fixes to nfp tls offload recently added to net-next. First 4 patches revolve around device mailbox communication, trying to make it more reliable. Next patch fixes statistical counter. Patch 6 improves the TX resync if device communication failed. Patch 7 makes sure we remove keys from memory after talking to FW. Patch 8 adds missing tls context initialization, we fill in the context information from various places based on the configuration and looks like we missed the init in the case of where TX is offloaded, but RX wasn't initialized yet. Patches 9 and 10 make the nfp driver undo TLS state changes if we need to drop the frame (e.g. due to DMA mapping error). Last but not least TLS fallback should not adjust socket memory after skb_orphan_partial().
