2025-08-26selftests/bpf: Remove entries from config.{arch} already present in configTiezhu Yang5-30/+0
`config.{arch}` had entries already present in `config`. When generating the config used by vmtest, concatenate the `config` file with the `config.{arch}` one, making those entries duplicated, so remove those duplications. Use the following command to get the differences: $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.x86_64) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.aarch64) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.riscv64) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.ppc64el) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.s390x) <(sort tools/testing/selftests/bpf/config) This is similar with commit 7a42af4b94f1 ("selftests/bpf: Remove entries from config.s390x already present in config").

2025-08-25selftests: net: add test for dst hint mechanism with directed broadcast ↵Oscar Maes2-0/+80
addresses Add a test for ensuring that the dst hint mechanism is used for directed broadcast addresses. This test relies on mausezahn for sending directed broadcast packets. Additionally, a high GRO flush timeout is set to ensure that packets will be received as lists. The test determines if the hint mechanism was used by checking the in_brd statistic using lnstat.

2025-08-25selftests: rtnetlink: skip tests if tools or feats are missingAlessandro Ratti1-0/+11
Some rtnetlink selftests assume the presence of ifconfig and iproute2 support for the `proto` keyword in `ip address` commands. These assumptions can cause test failures on modern systems (e.g. Debian Bookworm) where: - ifconfig is not installed by default - The iproute2 version lacks support for address protocol This patch improves test robustness by: - Skipping kci_test_promote_secondaries if ifconfig is missing - Skipping do_test_address_proto if ip address help does not mention proto These changes ensure the tests degrade gracefully by reporting SKIP instead of FAIL when prerequisites are not met, improving portability across systems.

2025-08-25selftests: drv-net: xdp: make sure we're actually testing native XDPJakub Kicinski1-2/+2
Kernel tries to be helpful and attach the XDP program in generic mode if the driver has no BPF ndo at all. Since the xdp.py tests all have "native" in their names this can be quite confusing. Force native / "drv" attachment. Note that netdevsim re-uses the generic handler as its "native" handler, so we'll maintain the test coverage of the generic mode that way. No need to test both explicitly, I reckon. Link: https://patch.msgid.link/20250822195645.1673390-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Add a selftest to verify bonding behavior when `lacp_active` is set to `off`. The test checks the following: - The passive LACP bond should not send LACPDUs before receiving a partner's LACPDU. - The transmitted LACPDUs must not include the active flag. - After transitioning to EXPIRED and DEFAULTED states, the passive side should still not initiate LACPDUs.

The test sometimes fails due to an unexpected number of loaded programs. e.g FAIL: 2 BPF programs loaded, expected 1 File "/usr/libexec/kselftests/net/./bpf_offload.py", line 940, in <module> progs = bpftool_prog_list(expected=1) File "/usr/libexec/kselftests/net/./bpf_offload.py", line 187, in bpftool_prog_list fail(True, "%d BPF programs loaded, expected %d" % File "/usr/libexec/kselftests/net/./bpf_offload.py", line 89, in fail tb = "".join(traceback.extract_stack().format()) However, the logs do not show which programs were actually loaded, making it difficult to debug the failure. Add printing of the loaded programs when a mismatch is detected to help troubleshoot such errors. The list is printed on a new line to avoid breaking the current log format.

2025-08-19selftests: net: Explicitly enable CONFIG_CRYPTO_SHA1 for IPsecEric Biggers2-0/+2
xfrm_policy.sh, nft_flowtable.sh, and vrf-xfrm-tests.sh use 'ip xfrm' with SHA-1, either 'auth sha1' or 'auth-trunc hmac(sha1)'. That requires CONFIG_CRYPTO_SHA1, which CONFIG_INET_ESP intentionally doesn't select (as per its help text). Previously, the config for these tests relied on CONFIG_CRYPTO_SHA1 being selected by the unrelated option CONFIG_IP_SCTP. Since CONFIG_IP_SCTP is being changed to no longer do that, instead add CONFIG_CRYPTO_SHA1 to the configs explicitly.

2025-08-19selftests: drv-net: ncdevmem: make configure_channels() support combined ↵Jakub Kicinski1-2/+76
channels ncdevmem tests that the kernel correctly rejects attempts to deactivate queues with MPs bound. Make the configure_channels() test support combined channels. Currently it tries to set the queue counts to rx N tx N-1, which only makes sense for devices which have IRQs per ring type. Most modern devices used combined IRQs/channels with both Rx and Tx queues. Since the math is total Rx == combined+Rx setting Rx when combined is non-zero will be increasing the total queue count, not decreasing as the test intends. Note that the test would previously also try to set the Tx ring count to Rx - 1, for some reason. Which would be 0 if the device has only 2 queues configured. With this change (device with 2 queues): setting channel count rx:1 tx:1 YNL set channels: Kernel error: 'requested channel counts are too low for existing memory provider setting (2)' Reviewed-by: Mina Almasry <almasrymina@google.com> Link: https://patch.msgid.link/20250815231513.381652-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
