Since we have mapped every mptcp reset reason definition in enum sk_rst_reason, introducing a new helper can cover some missing places where we have already set the subflow->reset_reason. Note: using SK_RST_REASON_NOT_SPECIFIED is the same as SK_RST_REASON_MPTCP_RST_EUNSPEC. They are both unknown. So we can convert it directly. Suggested-by:

It relies on what reset options in the skb are as rfc8684 says. Reusing this logic can save us much energy. This patch replaces most of the prior NOT_SPECIFIED reasons. Signed-off-by:

Reuse the dropreason logic to show the exact reason of tcp reset, so we can finally display the corresponding item in enum sk_reset_reason instead of reinventing new reset reasons. This patch replaces all the prior NOT_SPECIFIED reasons. Signed-off-by:

Add a new standalone file for the easy future extension to support both active reset and passive reset in the TCP/DCCP/MPTCP protocols. This patch only does the preparations for reset reason mechanism, nothing else changes. The reset reasons are divided into three parts: 1) reuse drop reasons for passive reset in TCP 2) our own independent reasons which aren't relying on other reasons at all 3) reuse MP_TCPRST option for MPTCP The benefits of a standalone reset reason are listed here: 1) it can cover more than one case, such as reset reasons in MPTCP, active reset reasons. 2) people can easily/fastly understand and maintain this mechanism. 3) we get unified format of output with prefix stripped. 4) more new reset reasons are on the way ... I will implement the basic codes of active/passive reset reason in those three protocols, which are not complete for this moment. For passive reset part in TCP, I only introduce the NO_SOCKET common case which could be set as an example. After this series applied, it will have the ability to open a new gate to let other people contribute more reasons into it :) Signed-off-by:

This patch adds support to per-packet Tx hardware timestamp request to AF_XDP zero-copy packet via XDP Tx metadata framework. Please note that user needs to enable Tx HW timestamp capability via igc_ioctl() with SIOCSHWTSTAMP cmd before sending xsk Tx hardware timestamp request. Same as implementation in RX timestamp XDP hints kfunc metadata, Timer 0 (adjustable clock) is used in xsk Tx hardware timestamp. i225/i226 have four sets of timestamping registers. *skb and *xsk_tx_buffer pointers are used to indicate whether the timestamping register is already occupied. Furthermore, a boolean variable named xsk_pending_ts is used to hold the transmit completion until the tx hardware timestamp is ready. This is because, for i225/i226, the timestamp notification event comes some time after the transmit completion event. The driver will retrigger hardware irq to clean the packet after retrieve the tx hardware timestamp. Besides, xsk_meta is added into struct igc_tx_timestamp_request as a hook to the metadata location of the transmit packet. When the Tx timestamp interrupt is fired, the interrupt handler will copy the value of Tx hwts into metadata location via xsk_tx_metadata_complete(). This patch is tested with tools/testing/selftests/bpf/xdp_hw_metadata on Intel ADL-S platform. Below are the test steps and results. Test Step 1: Run xdp_hw_metadata app ./xdp_hw_metadata <iface> > /dev/shm/result.log Test Step 2: Enable Tx hardware timestamp hwstamp_ctl -i <iface> -t 1 -r 1 Test Step 3: Run ptp4l and phc2sys for time synchronization Test Step 4: Generate UDP packets with 1ms interval for 10s trafgen --dev <iface> '{eth(da=<addr>), udp(dp=9091)}' -t 1ms -n 10000 Test Step 5: Rerun Step 1-3 with 10s iperf3 as background traffic Test Step 6: Rerun Step 1-4 with 10s iperf3 as background traffic Based on iperf3 results below, the impact of holding tx completion to throughput is not observable.

Jiri Pirko says: ==================== selftests: virtio_net: introduce initial testing infrastructure This patchset aims at introducing very basic initial infrastructure for virtio_net testing, namely it focuses on virtio feature testing. The first patch adds support for debugfs for virtio devices, allowing user to filter features to pretend to be driver that is not capable of the filtered feature. Example: $ cat /sys/bus/virtio/devices/virtio0/features 1110010111111111111101010000110010000000100000000000000000000000 $ echo "5" >/sys/kernel/debug/virtio/virtio0/filter_feature_add $ cat /sys/kernel/debug/virtio/virtio0/filter_features 5 $ echo "virtio0" > /sys/bus/virtio/drivers/virtio_net/unbind $ echo "virtio0" > /sys/bus/virtio/drivers/virtio_net/bind $ cat /sys/bus/virtio/devices/virtio0/features 1110000111111111111101010000110010000000100000000000000000000000 Leverage that in the last patch that lays ground for virtio_net selftests testing, including very basic F_MAC feature test. To run this, do: $ make -C tools/testing/selftests/ TARGETS=drivers/net/virtio_net/ run_tests It is assumed, as with lot of other selftests in the net group, that there are netdevices connected back-to-back. In this case, two virtio_net devices connected back to back. If you use "tap" qemu netdevice type, to configure this loop on a hypervisor, one may use this script: DEV1="$1" DEV2="$2" sudo tc qdisc add dev $DEV1 clsact sudo tc qdisc add dev $DEV2 clsact sudo tc filter add dev $DEV1 ingress protocol all pref 1 matchall action mirred egress redirect dev $DEV2 sudo tc filter add dev $DEV2 ingress protocol all pref 1 matchall action mirred egress redirect dev $DEV1 sudo ip link set $DEV1 up sudo ip link set $DEV2 up Another possibility is to use virtme-ng like this: $ vng --network=loop or directly: $ vng --network=loop -- make -C tools/testing/selftests/ TARGETS=drivers/net/virtio_net/ run_tests "loop" network type will take care of creating two "hubport" qemu netdevs putting them into a single hub. To do it manually with qemu, pass following command line options: -nic hubport,hubid=1,id=nd0,model=virtio-net-pci -nic hubport,hubid=1,id=nd1,model=virtio-net-pci ==================== Link: https://lore.kernel.org/r/20240424104049.3935572-1-jiri@resnulli.usSigned-off-by:

Currently there is no way for user to set what features the driver should obey or not, it is hard wired in the code. In order to be able to debug the device behavior in case some feature is disabled, introduce a debugfs infrastructure with couple of files allowing user to see what features the device advertises and to set filter for features used by driver. Example: $cat /sys/bus/virtio/devices/virtio0/features 1110010111111111111101010000110010000000100000000000000000000000 $ echo "5" >/sys/kernel/debug/virtio/virtio0/filter_feature_add $ cat /sys/kernel/debug/virtio/virtio0/filter_features 5 $ echo "virtio0" > /sys/bus/virtio/drivers/virtio_net/unbind $ echo "virtio0" > /sys/bus/virtio/drivers/virtio_net/bind $ cat /sys/bus/virtio/devices/virtio0/features 1110000111111111111101010000110010000000100000000000000000000000 Note that sysfs "features" now already exists, this patch does not touch it.

Current code checks if ping command output match hardcoded pattern: "10 packets transmitted, 10 received, 0% packet loss,". Such approach will work only from one ping program version (for which this test has been originally written). This patch address problem when ping with different summary output like "10 packets transmitted, 10 packets received, 0% packet" is used to run this test - for example one from busybox (as the test system runs in QEMU with rootfs created with buildroot). The fix is to modify output of ping command to be agnostic to ping version used on the platform. Signed-off-by:

Tony Nguyen says: ==================== net: intel: start The Great Code Dedup + Page Pool for iavf Alexander Lobakin says: Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and libie) and switch iavf to Page Pool. Details are in the commit messages; here's a summary: Not a secret there's a ton of code duplication between two and more Intel ethernet modules. Before introducing new changes, which would need to be copied over again, start decoupling the already existing duplicate functionality into a new module, which will be shared between several Intel Ethernet drivers. The first name that came to my mind was "libie" -- "Intel Ethernet common library". Also this sounds like "lovelie" (-> one word, no "lib I E" pls) and can be expanded as "lib Internet Explorer" :P The "generic", pure-software part is placed separately, so that it can be easily reused in any driver by any vendor without linking to the Intel pre-200G guts. In a few words, it's something any modern driver does the same way, but nobody moved it level up (yet). The series is only the beginning. From now on, adding every new feature or doing any good driver refactoring will remove much more lines than add for quite some time. There's a basic roadmap with some deduplications planned already, not speaking of that touching every line now asks: "can I share this?". The final destination is very ambitious: have only one unified driver for at least i40e, ice, iavf, and idpf with a struct ops for each generation. That's never gonna happen, right? But you still can at least try. PP conversion for iavf lands within the same series as these two are tied closely. libie will support Page Pool model only, so that a driver can't use much of the lib until it's converted. iavf is only the example, the rest will eventually be converted soon on a per-driver basis. That is when it gets really interesting.

This change was deliberately not included in commit 68aba004 ("net: sparx5: flower: fix fragment flags handling") as it's only needed for future proffing the code, since "mask" is currently only set in conjunction with the fragment flags.

Someone complains the message appears continuously. This occurs because the device is woken from UPS mode, and the driver re-loads the firmware. When the device enters runtime suspend and cable is unplugged, the device would enter UPS mode. If the runtime resume occurs, and the device is woken from UPS mode, the driver has to re-load the firmware and causes the message. If someone wakes the device continuously, the message would be shown continuously, too. Use dev_dbg to avoid it. Note that, the function could be called before register_netdev(), so I don't use netif_info() or netif_dbg(). Signed-off-by:

Enhance the quirk for Fibrestore 2.5G copper SFP module. The original commit e27aca37 ("net: sfp: add quirk for FS's 2.5G copper SFP") introducing the quirk says that the PHY is inaccessible, but that is not true. The module uses Rollball protocol to talk to the PHY, and needs a 4 second wait before probing it, same as FS 10G module. The PHY inside the module is Realtek RTL8221B-VB-CG PHY. The realtek driver recently gained support to set it up via clause 45 accesses. Signed-off-by:
