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.

2025-01-06selftests/bpf: Avoid generating untracked files when running bpf selftestsJiayuan Chen
Currently, when we run the BPF selftests with the following command: make -C tools/testing/selftests TARGETS=bpf SKIP_TARGETS="" The command generates untracked files and directories with make version less than 4.4: ''' Untracked files: (use "git add <file>..." to include in what will be committed) tools/testing/selftests/bpfFEATURE-DUMP.selftests tools/testing/selftests/bpffeature/ ''' We lost slash after word "bpf". The reason is slash appending code is as follow: ''' OUTPUT := $(OUTPUT)/ $(eval include ../../../build/Makefile.feature) OUTPUT := $(patsubst %/,%,$(OUTPUT)) ''' This way of assigning values to OUTPUT will never be effective for the variable OUTPUT provided via the command argument [1] and BPF makefile is called from parent Makfile(tools/testing/selftests/Makefile) like: ''' all: ... $(MAKE) OUTPUT=$$BUILD_TARGET -C $$TARGET ''' According to GNU make, we can use override Directive to fix this issue [2].

2025-01-03driver core: Constify API device_find_child() and adapt for various usagesZijun Hu
Constify the following API: struct device *device_find_child(struct device *dev, void *data, int (*match)(struct device *dev, void *data)); To : struct device *device_find_child(struct device *dev, const void *data, device_match_t match); typedef int (*device_match_t)(struct device *dev, const void *data); with the following reasons: - Protect caller's match data @*data which is for comparison and lookup and the API does not actually need to modify @*data. - Make the API's parameters (@match)() and @data have the same type as all of other device finding APIs (bus|class|driver)_find_device(). - All kinds of existing device match functions can be directly taken as the API's argument, they were exported by driver core. Constify the API and adapt for various existing usages. BTW, various subsystem changes are squashed into this commit to meet 'git bisect' requirement, and this commit has the minimal and simplest changes to complement squashing shortcoming, and that may bring extra code improvement.

2025-01-02cxl/pci: Add CXL Type 1/2 support to cxl_dvsec_rr_decode()Alejandro Lucero
In cxl_dvsec_rr_decode() the pci driver expects to retrieve a cxlds, struct cxl_dev_state, from the driver_data field of struct device. While that works for Type 3, drivers for Type 1/2 devices may not put a cxlds in the driver_data field. In preparation for supporting Type 1/2 devices, replace parameter 'struct device' with 'struct cxl_dev_state' in cxl_dvsec_rr_decode().

2024-12-30selftests/bpf: fix veristat comp mode with new statsMahe Tardy
Commit 82c1f13de315 ("selftests/bpf: Add more stats into veristat") introduced new stats, added by default in the CSV output, that were not added to parse_stat_value, used in parse_stats_csv which is used in comparison mode. Thus it broke comparison mode altogether making it fail with "Unrecognized stat #7" and EINVAL. One quirk is that PROG_TYPE and ATTACH_TYPE have been transformed to strings using libbpf_bpf_prog_type_str and libbpf_bpf_attach_type_str respectively. Since we might not want to compare those string values, we just skip the parsing in this patch. We might want to translate it back to the enum value or compare the string value directly.

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.

2024-12-20selftests/alsa: Fix circular dependency involving global-timerLi Zhijian
The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular dependency on the global-timer target due to its inclusion in $(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency warning during the build process. To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change ensures that libatest.so is built before any other targets that require it, without creating a circular dependency. This fix addresses the following warning: make[4]: Entering directory 'tools/testing/selftests/alsa' make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped. make[4]: Nothing to be done for 'all'. make[4]: Leaving directory 'tools/testing/selftests/alsa' Cc: Mark Brown <broonie@kernel.org> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Link: https://patch.msgid.link/20241218025931.914164-1-lizhijian@fujitsu.com Signed-off-by: Takashi Iwai <tiwai@suse.de>

2024-12-19Merge tag 'kvm-selftests-treewide-6.14' of https://github.com/kvm-x86/linux ↵Paolo Bonzini
into HEAD KVM selftests "tree"-wide changes for 6.14: - Rework vcpu_get_reg() to return a value instead of using an out-param, and update all affected arch code accordingly. - Convert the max_guest_memory_test into a more generic mmu_stress_test. The basic gist of the "conversion" is to have the test do mprotect() on guest memory while vCPUs are accessing said memory, e.g. to verify KVM and mmu_notifiers are working as intended. - Play nice with treewrite builds of unsupported architectures, e.g. arm (32-bit), as KVM selftests' Makefile doesn't do anything to ensure the target architecture is actually one KVM selftests supports. - Use the kernel's $(ARCH) definition instead of the target triple for arch specific directories, e.g. arm64 instead of aarch64, mainly so as not to be different from the rest of the kernel.
