Wed, 22 Apr 2026 16:06:47 +0200

tools/selftests: Add a VXLAN+IPsec traffic testThere are VXLAN tests and IPsec tests, but there is no test thatcombines the two protocols and exercises the tunnel-over-ipsec codepaths. Fix that by adding a traffic test with VXLAN and IPsec usingcrypto offload. This is runnable on HW which supports ESP offload (so nonsim unfortunately).Traffic is done with iperf3 and the test validates that there are nopacket drops and iperf3 can get to at least 100 Mbps (a veryconservative value on today's crypto offload HW, as it can typicallyreach multi-Gbps rates).Ran right now, the test fails due to a recently exposed bug in xfrm,which will be fixed in the next patch: # ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py TAP version 13 1..4 # Check| At ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py, # line 161, in test_vxlan_ipsec_crypto_offload: # Check| ksft_eq(drops_after - drops_before, 0, # Check failed 189 != 0 TX drops during VXLAN+IPsec # Check| At ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py, # line 163, in test_vxlan_ipsec_crypto_offload: # Check| ksft_ge(bw_gbps, 0.1, # Check failed 0.0015058278404812596 < 0.1 Minimum 100Mbps over # VXLAN+IPsec not ok 1 ipsec_vxlan.test_vxlan_ipsec_crypto_offload.outer_v4_inner_v4 ...Signed-off-by: Cosmin Ratiu Signed-off-by: Steffen Klassert List of files: /linux/tools/testing/selftests/drivers/net/hw/Makefile

Sun, 12 Apr 2026 19:54:35 +0200

Merge branch 'add-tso-map-once-dma-helpers-and-bnxt-sw-uso-support'Joe Damato says:====================Add TSO map-once DMA helpers and bnxt SW USO supportGreetings:This series extends net/tso to add a data structure and some helpers allowingdrivers to DMA map headers and packet payloads a single time. The helpers canthen be used to reference slices of shared mapping for each segment. Thishelps to avoid the cost of repeated DMA mappings, especially on systems whichuse an IOMMU. N per-packet DMA maps are replaced with a single map for theentire GSO skb. As of v3, the series uses the DMA IOVA API (as suggested byLeon [1]) and provides a fallback path when an IOMMU is not in use. The DMAIOVA API provides even better efficiency than the v2; see below.The added helpers are then used in bnxt to add support for software UDPSegmentation Offloading (SW USO) for older bnxt devices which do not havesupport for USO in hardware. Since the helpers are generic, other driverscan be extended similarly.The v2 showed a ~4x reduction in DMA mapping calls at the same wire packetrate on production traffic with a bnxt device. The v3, however, shows a largerreduction of about ~6x at the same wire packet rate. This is thanks to Leon'ssuggestion of using the DMA IOVA API [1].Special care is taken to make bnxt ethtool operations work correctly: the ringsize cannot be reduced below a minimum threshold while USO is enabled andgrowing the ring automatically re-enables USO if it was previously blocked.This v10 contains some cosmetic changes (wrapping long lines), moves the testto the correct directory, and attempts to fix the slot availability checkadded in the v9.I re-ran the python test and the test passed on my bnxt system. I also ranthis on a production system.====================Link: https://patch.msgid.link/20260408230607.2019402-1-joe@dama.toSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/hw/Makefile

Merge branch 'netkit-support-for-io_uring-zero-copy-and-af_xdp'Daniel Borkmann says:====================netkit: Support for io_uring zero-copy and AF_XDPContainers use virtual netdevs to route traffic from a physical netdevin the host namespace. They do not have access to the physical netdevin the host and thus can't use memory providers or AF_XDP that requirereconfiguring/restarting queues in the physical netdev.This patchset adds the concept of queue leasing to virtual netdevs thatallow containers to use memory providers and AF_XDP at native speed.Leased queues are bound to a real queue in a physical netdev and actas a proxy.Memory providers and AF_XDP operations take an ifindex and queue id,so containers would pass in an ifindex for a virtual netdev and a queueid of a leased queue, which then gets proxied to the underlying realqueue.We have implemented support for this concept in netkit and tested thelatter against Nvidia ConnectX-6 (mlx5) as well as Broadcom BCM957504(bnxt_en) 100G NICs.

Merge branch 'selftests-drivers-bash-support-for-remote-traffic-generators'Ioana Ciornei says:====================selftests: drivers: bash support for remote traffic generatorsThis patch set aims to add the necessary support so that bash writtenselftests are also able to easily run with a remote traffic generatorsystem, either be it in another netns or one accessible through ssh.This patch set is a result of the discussion from v1:https://lore.kernel.org/all/20260303084330.340b6459@kernel.org/Even though the python infrastructure is already established, somethings are easier in bash and it would be a shame to leave behind thebash tests that we already have.This support is based on the requirements described in thetools/testing/selftests/drivers/net/README.rst file.Mainly, the drivers/net selftests should be able to run on a interfacespecified through the NETIF env variable. On top of that, variables suchas REMOTE_TYPE and REMOTE_ARGS define how the remote traffic generatorcan be accessed. Patch 3/10 parses these env variables and constructs theNETIFS array that bash tests are accustomed to. This is with theintention of enabling already written tests to incur minimal changes.The second patch also defines the TARGETS array which will hold thenecessary information about the target on which a specific interfaceis located.For example, a net.config which looks like below: NETIF=eth0 LOCAL_V4=192.168.1.1 REMOTE_V4=192.168.1.2 REMOTE_TYPE=ssh REMOTE_ARGS=root@192.168.1.2will generate the NETIFS and TARGETS arrays with the following data. NETIFS[p1]="eth0" NETIFS[p2]="eth2" TARGETS[eth0]="local:" TARGETS[eth2]="ssh:root@192.168.1.2"The above will be true if on the remote target, the interface which hasthe 192.168.1.2 address is named eth2.The values held in the TARGETS array will be used by the new 'run_on'helper added in patch 2/10 to know how to run a specific command, on thelocal system, on another netns or by using ssh. Patch 4/10 updates somehelpers to use run_on so that, for example, lib.sh is able to ensurestable MAC addresses even with the remote interface located in anothernetns.The next 5 patches, 5/10-9/10 update the ethtool_rmon.sh script so that itcan work with the kselftest infrastructure and the newNETIF/REMOTE_TYPE etc way of working. Beside updating each ip link orethtool command to use the run_on helper, the patches also remove anytesting done on the remote interface.The last patch adds a new test which checks the standard counters -eth-ctrl, eth-mac and pause - and uses the new infrastructure put inplace by the first patches.With this patch set, both tests can be run using a net.config file andrun_kselftest.sh as shown below. $ make -C tools/testing/selftests/ TARGETS="drivers/net drivers/net/hw" \ install INSTALL_PATH=/tmp/ksft-net-drv $ cd /tmp/ksft-net-drv/ $ cat > ./drivers/net/net.config < List of files: /linux/tools/testing/selftests/drivers/net/hw/Makefile

3016574ea2f8a8cff69286574ac027fa5aed5a81 - selftests: drivers: hw: add test for the ethtool standard counters

Mon, 30 Mar 2026 17:29:33 +0200

selftests: drivers: hw: add test for the ethtool standard countersAdd a new selftest - ethtool_std_stats.sh - which validates theeth-ctrl, eth-mac and pause standard statistics exported by aninterface. Collision related eth-mac counters as well as the error oneswill be checked against zero since that is the most likely correctscenario.The central part of this patch is the traffic_test() function whichgathers the 'before' counter values, sends a batch of traffic and theninterrogates again the same counters in order to determine if the deltais on target. The function receives an array through which the callercan request what counters to be interrogated and, for each of them, whatis their target delta value.The output from this selftest looks as follows on a LX2160ARDB board: $ ./run_kselftest.sh -t drivers/net/hw:ethtool_std_stats.sh TAP version 13 1..1 # timeout set to 0 # selftests: drivers/net/hw: ethtool_std_stats.sh # TAP version 13 # 1..26 # ok 1 ethtool_std_stats.eth-ctrl-MACControlFramesTransmitted # ok 2 ethtool_std_stats.eth-ctrl-MACControlFramesReceived # ok 3 ethtool_std_stats.eth-mac-FrameCheckSequenceErrors # ok 4 ethtool_std_stats.eth-mac-AlignmentErrors # ok 5 ethtool_std_stats.eth-mac-FramesLostDueToIntMACXmitError # ok 6 ethtool_std_stats.eth-mac-CarrierSenseErrors # SKIP # ok 7 ethtool_std_stats.eth-mac-FramesLostDueToIntMACRcvError # ok 8 ethtool_std_stats.eth-mac-InRangeLengthErrors # SKIP # ok 9 ethtool_std_stats.eth-mac-OutOfRangeLengthField # SKIP # ok 10 ethtool_std_stats.eth-mac-FrameTooLongErrors # SKIP # ok 11 ethtool_std_stats.eth-mac-FramesAbortedDueToXSColls # SKIP # ok 12 ethtool_std_stats.eth-mac-SingleCollisionFrames # SKIP # ok 13 ethtool_std_stats.eth-mac-MultipleCollisionFrames # SKIP # ok 14 ethtool_std_stats.eth-mac-FramesWithDeferredXmissions # SKIP # ok 15 ethtool_std_stats.eth-mac-LateCollisions # SKIP # ok 16 ethtool_std_stats.eth-mac-FramesWithExcessiveDeferral # SKIP # ok 17 ethtool_std_stats.eth-mac-BroadcastFramesXmittedOK # ok 18 ethtool_std_stats.eth-mac-OctetsTransmittedOK # ok 19 ethtool_std_stats.eth-mac-BroadcastFramesReceivedOK # ok 20 ethtool_std_stats.eth-mac-OctetsReceivedOK # ok 21 ethtool_std_stats.eth-mac-FramesTransmittedOK # ok 22 ethtool_std_stats.eth-mac-MulticastFramesXmittedOK # ok 23 ethtool_std_stats.eth-mac-FramesReceivedOK # ok 24 ethtool_std_stats.eth-mac-MulticastFramesReceivedOK # ok 25 ethtool_std_stats.pause-tx_pause_frames # ok 26 ethtool_std_stats.pause-rx_pause_frames # # 10 skipped test(s) detected.

For example, on a LS1028ARDB the selftestoutput will reflect the fact that neither the ENETC MAC, nor the Felixswitch MAC are able to detect Tx pause frames injected by software. $ ./run_kselftest.sh -t drivers/net/hw:ethtool_std_stats.sh (...) # # software sent pause frames not detected # ok 25 ethtool_std_stats.pause-tx_pause_frames # XFAIL # ok 26 ethtool_std_stats.pause-rx_pause_framesSigned-off-by: Ioana Ciornei Acked-by: Petr Machata Link: https://patch.msgid.link/20260330152933.2195885-10-ioana.ciornei@nxp.comSigned-off-by: Paolo Abeni List of files: /linux/tools/testing/selftests/drivers/net/hw/Makefile

e3cdf6cf5fc6db0643723083e2c70fffe098e249 - selftests: drv-net: xdp: Add rss_hash metadata tests

Wed, 25 Mar 2026 21:09:52 +0100

selftests: drv-net: xdp: Add rss_hash metadata testsThis test loads xdp_metadata.bpf which calls bpf_xdp_metadata_rx_hash() onincoming packets. The metadata from that packet is then sent to a BPFmap for validation. It borrows structure from xdp.py, reusing commonfunctions.The test checks the device's xdp-rx-metadata-features via netlinkbefore running and skips on devices that do not advertise hash support.This can be run on veth devices as well as real hardware.The test is fairly simple and just verifies that a TCP or UDP packet can beidentified as an L4 flow. This minimal test also passes if run on a vethdevice.Signed-off-by: Chris J Arges Link: https://patch.msgid.link/20260325201139.2501937-7-carges@cloudflare.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/hw/Makefile
