* Merge branch 'mptcp-selftests'David S. Miller2024-04-086-259/+382

Patch 1 checks that TC is available in selftests requiring it. Patch 2 adds 'ms' units in TC commands, to avoid confusions. Patches 3-9 are some prerequisites for patch 10: some export code from mptcp_join.sh to mptcp_lib.sh, to be re-used in pm_netlink.sh, mptcp_sockopt.sh and simult_flows.sh ; and others add helpers to pm_netlink.sh to easily support both 'ip mptcp' and 'pm_nl_ctl' tools to interact with the in-kernel MPTCP path-manager. Patch 10 adds a '-i' parameter in mptcp_sockopt.sh, pm_netlink.sh, and simult_flows.sh to use 'ip mptcp' tool instead of 'pm_nl_ctl'. Patch 11 fixes some ShellCheck warnings in pm_netlink.sh, in order to drop a ShellCheck's 'disable' instruction. ==================== Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Signed-off-by: David S.

Use these two helpers in mptcp_join.sh and pm_netlink.sh to replace all 'pm_nl_ctl get' commands and outputs of 'pm_nl_ctl dump/get'.

* net: usb: ax88179_178a: non necessary second random mac addressJose Ignacio Tornos Martinez2024-04-081-1/+0
| | | | | | | | | | | | | | | | If the mac address can not be read from the device registers or the devicetree, a random address is generated, but this was already done from usbnet_probe, so it is not necessary to call eth_hw_addr_random from here again to generate another random address. Indeed, when reset was also executed from bind, generate another random mac address invalidated the check from usbnet_probe to configure if the assigned mac address for the interface was random or not, because it is comparing with the initial generated random address. Now, with only a reset from open operation, it is just a harmless simplification. Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> Signed-off-by: David S.

* pfcp: avoid copy warning by simplifing codeMichal Swiatkowski2024-04-081-3/+2

[-Werror=attribute-warning] 553 | __write_overflow_field(p_size_field, size);" It is a false-positivie caused by ambiguity of the union. However, as Arnd noticed, copying here is unescessary. The code can be simplified to avoid calling ip_tunnel_info_opts_set(), which is doing copying, setting flags and options_len. Set correct flags and options_len directly on tun_info.

YAML/Netlink gives us the ability to easily interface with Netlink in higher level laguages. In particular, there is a Python library already available in tree, under tools/net. Add the scaffolding which allows writing tests using this library. The "scaffolding" is needed because the library lives under tools/net and uses YAML files from under Documentation/. So we need a small amount of glue code to find those things and add them to TEST_FILES. This series adds both a basic SW sanity test and driver test which can be run against netdevsim or a real device. When I develop core code I usually test with netdevsim, then a real device, and then a backport to Meta's kernel. Because of the lack of integration, until now I had to throw away the (YNL-based) test script and netdevsim code. Running tests in tree directly: $ ./tools/testing/selftests/net/nl_netdev.py KTAP version 1 1..2 ok 1 nl_netdev.empty_check ok 2 nl_netdev.lo_check # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0 in tree via make: $ make -C tools/testing/selftests/ TARGETS=net \ TEST_PROGS=nl_netdev.py TEST_GEN_PROGS="" run_tests [ ... ] and installed externally, all seem to work: $ make -C tools/testing/selftests/ TARGETS=net \ install INSTALL_PATH=/tmp/ksft-net $ /tmp/ksft-net/run_kselftest.sh -t net:nl_netdev.py [ ... ] For driver tests I followed the lead of net/forwarding and get the device name from env and/or a config file. v3: - fix up netdevsim C - various small nits in other patches (see changelog in patches) v2: https://lore.kernel.org/all/20240403023426.1762996-1-kuba@kernel.org/ - don't add to TARGETS, create a deperate variable with deps - support and use with - support and use passing arguments to tests v1: https://lore.kernel.org/all/20240402010520.1209517-1-kuba@kernel.org/ ==================== Signed-off-by: David S.

Devices which support pause or FEC configuration should also report the relevant stats. nsim was missing FEC stats completely, some of the qstats and pause stats required toggling a debugfs knob.

With the current model, the transceiver's PHY can't be used for operations such as cable testing, timestamping, macsec offload, etc. The reason being that most of the logic for these configuration, coming from either ethtool netlink or ioctls tend to use netdev->phydev, which in multi-phy systems will reference the PHY closest to the MAC. Introduce a numbering scheme allowing to enumerate PHY devices that belong to any netdev, which can in turn allow userspace to take more precise decisions with regard to each PHY's configuration. The numbering is maintained per-netdev, in a phy_device_list. The numbering works similarly to a netdevice's ifindex, with identifiers that are only recycled once INT_MAX has been reached. This prevents races that could occur between PHY listing and SFP transceiver removal/insertion. The identifiers are assigned at phy_attach time, as the numbering depends on the netdevice the phy is attached to. The PHY index can be re-used for PHYs that are persistent.

The statistics counters added are based on what I believe are common patterns/behaviors found across various hardware timestamping implementations seen in the kernel tree today. The mlx5 family of devices is used as the PoC for this patch series. Other vendors are more than welcome to chime in on this series.
