2025-01-09netconsole: selftest: verify userdata entry limitBreno Leitao
Add a new selftest for netconsole that tests the userdata entry limit functionality. The test performs two key verifications: 1. Create MAX_USERDATA_ITEMS (16) userdata entries successfully 2. Confirm that attempting to create an additional userdata entry fails The selftest script uses the netcons library and checks the behavior by attempting to create entries beyond the maximum allowed limit.

2025-01-09netconsole: selftest: Delete all userdata keysBreno Leitao
Modify the cleanup function to remove all userdata keys created during the test, instead of just deleting a single predefined key. This ensures a more thorough cleanup of temporary resources. Move the KEY_PATH variable definition inside the set_user_data function to reduce global variables and improve encapsulation. The KEY_PATH variable is now dynamically created when setting user data. This change has no effect on the current test, while improving an upcoming test that would create several userdata entries.

2025-01-09netconsole: selftest: Split the helpers from the selftestBreno Leitao
Split helper functions from the netconsole basic test into a separate library file to enable reuse across different netconsole tests. This change only moves the existing helper functions to lib/sh/lib_netcons.sh while preserving the same test functionality. The helpers provide common functions for: - Setting up network namespaces and interfaces - Managing netconsole dynamic targets - Setting user data - Handling test dependencies - Cleanup operations Do not make any change in the code, other than the mechanical separation.

2025-01-09tools: ynl-gen-c: improve support for empty nestsJakub Kicinski
Empty nests are the same size as a flag at the netlink level (just a 4 byte nlattr without a payload). They are sometimes useful in case we want to only communicate a presence of something but may want to add more details later. This may be the case in the upcoming io_uring ZC patches, for example. Improve handling of nested empty structs. We already support empty structs since a lot of netlink replies are empty, but for nested ones we need minor tweaks to avoid pointless empty lines and unused variables.

2025-01-07selftests/net: packetdrill: report benign debug flakes as xfailWillem de Bruijn
A few recently added packetdrill tests that are known time sensitive (e.g., because testing timestamping) occasionally fail in debug mode: https://netdev.bots.linux.dev/contest.html?executor=vmksft-packetdrill-dbg These failures are well understood. Correctness of the tests is verified in non-debug mode. Continue running in debug mode also, to keep coverage with debug instrumentation. But, only in debug mode, mark these tests with well understood timing issues as XFAIL (known failing) rather than FAIL when failing. Introduce an allow list xfail_list with known cases. Expand the ktap infrastructure with XFAIL support.

2025-01-06netkit: Allow for configuring needed_{head,tail}roomDaniel Borkmann
Allow the user to configure needed_{head,tail}room for both netkit devices. The idea is similar to 163e529200af ("veth: implement ndo_set_rx_headroom") with the difference that the two parameters can be specified upon device creation. By default the current behavior stays as is which is needed_{head,tail}room is 0. In case of Cilium, for example, the netkit devices are not enslaved into a bridge or openvswitch device (rather, BPF-based redirection is used out of tcx), and as such these parameters are not propagated into the Pod's netns via peer device. Given Cilium can run in vxlan/geneve tunneling mode (needed_headroom) and/or be used in combination with WireGuard (needed_{head,tail}room), allow the Cilium CNI plugin to specify these two upon netkit device creation.

2024-12-27rtla/timerlat: Fix histogram ALL for zero samplesTomas Glozar
rtla timerlat hist currently computers the minimum, maximum and average latency even in cases when there are zero samples. This leads to nonsensical values being calculated for maximum and minimum, and to divide by zero for average. A similar bug is fixed by 01b05fc0e5f3 ("rtla/timerlat: Fix histogram report when a cpu count is 0") but the bug still remains for printing the sum over all CPUs in timerlat_print_stats_all. The issue can be reproduced with this command: $ rtla timerlat hist -U -d 1s Index over: count: min: avg: max: Floating point exception (core dumped) (There are always no samples with -U unless the user workload is created.) Fix the bug by omitting max/min/avg when sample count is zero, displaying a dash instead, just like we already do for the individual CPUs. The logic is moved into a new function called format_summary_value, which is used for both the individual CPUs and for the overall summary.

2024-12-24sched_ext: Fix dsq_local_on selftestTejun Heo
The dsp_local_on selftest expects the scheduler to fail by trying to schedule an e.g. CPU-affine task to the wrong CPU. However, this isn't guaranteed to happen in the 1 second window that the test is running. Besides, it's odd to have this particular exception path tested when there are no other tests that verify that the interface is working at all - e.g. the test would pass if dsp_local_on interface is completely broken and fails on any attempt. Flip the test so that it verifies that the feature works. While at it, fix a typo in the info message.
