selftests: fib_rule_tests: Add DSCP selector connect tests

2024-09-14T04:15:45Z

Test that locally generated traffic from a socket that specifies a DS Field using the IP_TOS / IPV6_TCLASS socket options is correctly redirected using a FIB rule that matches on DSCP. Add negative tests to verify that the rule is not it when it should not. Test with both IPv4 and IPv6 and with both TCP and UDP sockets.

selftests/net: packetdrill: import tcp/slow_start

2024-09-13T02:04:38Z

Same import process as previous tests. Also add CONFIG_NET_SCH_FQ to config, as one test uses that. Same test process as previous tests. Both with and without debug mode.

selftests/net: packetdrill: import tcp/zerocopy

2024-09-13T02:04:37Z

Same as initial tests, import verbatim from github.com/google/packetdrill, aside from: - update `source ./defaults.sh` path to adjust for flat dir - add SPDX headers - remove author statements if any - drop blank lines at EOF (new) Also import set_sysctls.py, which many scripts depend on to set sysctls and then restore them later. This is no longer strictly needed for namespacified sysctl. But not all sysctls are namespacified, and doesn't hurt if they are.

selftests/net: packetdrill: run in netns and expand config

2024-09-13T02:04:37Z

Run packetdrill tests inside netns. They may change system settings, such as sysctl. Also expand config with a few more needed CONFIGs.

Cross-merge networking fixes after downstream PR. No conflicts (sort of) and no adjacent changes. This merge reverts commit b3c9e65eb227 ("net: hsr: remove seqnr_lock") from net, as it was superseded by commit 430d67bdcb04 ("net: hsr: Use the seqnr lock for frames received via interlink port.") in net-next.

selftests: add ncdevmem, netcat for devmem TCP

2024-09-12T03:44:32Z

ncdevmem is a devmem TCP netcat. It works similarly to netcat, but it sends and receives data using the devmem TCP APIs. It uses udmabuf as the dmabuf provider. It is compatible with a regular netcat running on a peer, or a ncdevmem running on a peer. In addition to normal netcat support, ncdevmem has a validation mode, where it sends a specific pattern and validates this pattern on the receiver side to ensure data integrity.

selftests: mptcp: include net_helper.sh file

2024-09-11T22:18:20Z

Similar to the previous commit, the net_helper.sh file from the parent directory is used by the MPTCP selftests and it needs to be present when running the tests. This file then needs to be listed in the Makefile to be included when exporting or installing the tests, e.g. with: make -C tools/testing/selftests \ TARGETS=net/mptcp \ install INSTALL_PATH=$KSFT_INSTALL_PATH cd $KSFT_INSTALL_PATH ./run_kselftest.sh -c net/mptcp Fixes: 1af3bc912eac ("selftests: mptcp: lib: use wait_local_port_listen helper") Signed-off-by: Matthieu Baerts (NGI0) Link: https://patch.msgid.link/20240910-net-selftests-mptcp-fix-install-v1-3-8f124aa9156d@kernel.org Signed-off-by: Jakub Kicinski

selftests: mptcp: join: restrict fullmesh endp on 1st sf

2024-09-11T22:18:19Z

A new endpoint using the IP of the initial subflow has been recently added to increase the code coverage. But it breaks the test when using old kernels not having commit 86e39e04482b ("mptcp: keep track of local endpoint still available for each msk"), e.g. on v5.15. Similar to commit d4c81bbb8600 ("selftests: mptcp: join: support local endpoint being tracked or not"), it is possible to add the new endpoint conditionally, by checking if "mptcp_pm_subflow_check_next" is present in kallsyms: this is not directly linked to the commit introducing this symbol but for the parent one which is linked anyway. So we can know in advance what will be the expected behaviour, and add the new endpoint only when it makes sense to do so.
