2023-07-19selftests: tc: set timeout to 15 minutesMatthieu Baerts1-0/+1
When looking for something else in LKFT reports [1], I noticed that the TC selftest ended with a timeout error: not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds The timeout had been introduced 3 years ago, see the Fixes commit below. This timeout is only in place when executing the selftests via the kselftests runner scripts. I guess this is not what most TC devs are using and nobody noticed the issue before. The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks like it is plenty more time than what it takes in "normal" conditions.

2023-07-19kunit: qemu_configs: Enable all architectural features for arm64Mark Brown1-1/+1
While it probably doesn't make a huge difference given the current KUnit coverage we will get the best coverage of arm64 architecture features if we specify -cpu=max rather than picking a specific CPU, this will include all architecture features that qemu supports including many which have not yet made it into physical implementations. Due to performance issues emulating the architected pointer authentication algorithm it is recommended to use the implementation defined algorithm that qemu has instead, this should make no meaningful difference to the coverage and will run the tests faster.

2023-07-15torture: Loosen .config checks for KCSAN kernelsPaul E. McKenney1-0/+7
KCSAN enables some Kconfig options unilaterally and unconditionally, including CONFIG_PROVE_LOCKING. This in turn enables CONFIG_PROVE_RCU and CONFIG_PREEMPT_COUNT, which conflicts with constraints in SRCU-T, TRACE01, and TREE10, which in turn causes rcutorture to emit spurious configuration complaints. This commit therefore forgives configuration complaints involving CONFIG_PROVE_RCU and CONFIG_PREEMPT_COUNT. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

2023-07-15torture: Place --bootargs parameters at end of -append listPaul E. McKenney7-12/+17
Currently, the kernel boot parameters specified by the kvm.sh --bootargs parameter are placed near the beginning of the -append list that is passed to qemu. This means that in the not-uncommon case of a kernel boot parameter where the last argument wins, the --bootargs list overrides neither the list in the .boot file nor the additional parameters supplied by the rcutorture scripting. This commit therefore places the kernel boot parameters specified by the kvm.sh --bootargs parameter at the end of qemu's -append list. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

The CBMC-based formal-verification testing for SRCU was quite the thing back in 2016, but the problem is that SRCU changes too quickly for the scripting to keep up.

2023-07-14selftests/arm64: fix build failure during the "emit_tests" stepJohn Hubbard1-1/+1
The build failure reported in [1] occurred because commit <9fc96c7c19df> ("selftests: error out if kernel header files are not yet built") added a new "kernel_header_files" dependency to "all", and that triggered another, pre-existing problem. Specifically, the arm64 selftests override the emit_tests target, and that override improperly declares itself to depend upon the "all" target. This is a problem because the "emit_tests" target in lib.mk was not intended to be overridden. emit_tests is a very simple, sequential build target that was originally invoked from the "install" target, which in turn, depends upon "all". That approach worked for years. But with 9fc96c7c19df in place, emit_tests failed, because it does not set up all of the elaborate things that "install" does. And that caused the new "kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being correct) to fail. Some detail: The "all" target is .PHONY. Therefore, each target that depends on "all" will cause it to be invoked again, and because dependencies are managed quite loosely in the selftests Makefiles, many things will run, even "all" is invoked several times in immediate succession. So this is not a "real" failure, as far as build steps go: everything gets built, but "all" reports a problem when invoked a second time from a bad environment. To fix this, simply remove the unnecessary "all" dependency from the overridden emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all". An alternative approach would be to harden the emit_tests target so that it can depend upon "all", but that's a lot more complicated and hard to get right, and doesn't seem worth it, especially given that emit_tests should probably not be overridden at all.

2023-07-14selftests/riscv: fix potential build failure during the "emit_tests" stepJohn Hubbard1-1/+1
The riscv selftests (which were modeled after the arm64 selftests) are improperly declaring the "emit_tests" target to depend upon the "all" target. This approach, when combined with commit 9fc96c7c19df ("selftests: error out if kernel header files are not yet built"), has caused build failures [1] on arm64, and is likely to cause similar failures for riscv. To fix this, simply remove the unnecessary "all" dependency from the emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all". An alternative approach would be to harden the emit_tests target so that it can depend upon "all", but that's a lot more complicated and hard to get right, and doesn't seem worth it, especially given that emit_tests should probably not be overridden at all.

2023-07-14selftests/bpf: add testcase for TRACING with 6+ argumentsMenglong Dong12-15/+332
Add fentry_many_args.c and fexit_many_args.c to test the fentry/fexit with 7/11 arguments. As this feature is not supported by arm64 yet, we disable these testcases for arm64 in DENYLIST.aarch64. We can combine them with fentry_test.c/fexit_test.c when arm64 is supported too. Correspondingly, add bpf_testmod_fentry_test7() and bpf_testmod_fentry_test11() to bpf_testmod.c Meanwhile, add bpf_modify_return_test2() to test_run.c to test the MODIFY_RETURN with 7 arguments. Add bpf_testmod_test_struct_arg_7/bpf_testmod_test_struct_arg_7 in bpf_testmod.c to test the struct in the arguments. And the testcases passed on x86_64: ./test_progs -t fexit Summary: 5/14 PASSED, 0 SKIPPED, 0 FAILED ./test_progs -t fentry Summary: 3/2 PASSED, 0 SKIPPED, 0 FAILED ./test_progs -t modify_return Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED ./test_progs -t tracing_struct Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Menglong Dong <imagedong@tencent.com> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/r/20230713040738.1789742-4-imagedong@tencent.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in. But the parsing failed to handle this case. - Add selftest to struct sizes for user events - Fix sample code for direct trampolines. The sample code for direct trampolines attached to handle_mm_fault(). But the prototype changed and the direct trampoline sample code was not updated. Direct trampolines needs to have the arguments correct otherwise it can fail or crash the system. - Remove unused ftrace_regs_caller_ret() prototype. - Quiet false positive of FORTIFY_SOURCE Due to backward compatibility, the structure used to save stack traces in the kernel had a fixed size of 8. This structure is exported to user space via the tracing format file. A change was made to allow more than 8 functions to be recorded, and user space now uses the size field to know how many functions are actually in the stack. But the structure still has size of 8 (even though it points into the ring buffer that has the required amount allocated to hold a full stack. This was fine until the fortifier noticed that the memcpy(&entry->caller, stack, size) was greater than the 8 functions and would complain at runtime about it. Hide this by using a pointer to the stack location on the ring buffer instead of using the address of the entry structure caller field. - Fix a deadloop in reading trace_pipe that was caused by a mismatch between ring_buffer_empty() returning false which then asked to read the data, but the read code uses rb_num_of_entries() that returned zero, and causing a infinite "retry". - Fix a warning caused by not using all pages allocated to store ftrace functions, where this can happen if the linker inserts a bunch of "NULL" entries, causing the accounting of how many pages needed to be off. - Fix histogram synthetic event crashing when the start event is removed and the end event is still using a variable from it - Fix memory leak in freeing iter->temp in tracing_release_pipe() * tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix memory leak of iter->temp when reading trace_pipe tracing/histograms: Add histograms to hist_vars if they have referenced variables tracing: Stop FORTIFY_SOURCE complaining about stack trace caller ftrace: Fix possible warning on checking all pages used in ftrace_process_locs() ring-buffer: Fix deadloop issue on reading trace_pipe tracing: arm64: Avoid missing-prototype warnings selftests/user_events: Test struct size match cases tracing/user_events: Fix struct arg size match check x86/ftrace: Remove unsued extern declaration ftrace_regs_caller_ret() arm64: ftrace: Add direct call trampoline samples support samples: ftrace: Save required argument registers in sample trampolines

2023-07-13regmap: Provide user selectable option to enable regmapMark Brown1-0/+2
Since apparently enabling all the KUnit tests shouldn't enable any new subsystems it is hard to enable the regmap KUnit tests in normal KUnit testing scenarios that don't enable any drivers. Add a Kconfig option to help with this and include it in the KUnit all tests config.

2023-07-13selftests/nolibc: drop test chmod_netThomas Weißschuh1-1/+0
The test relies on /proc/$PID/net to allow chmod() operations. It is the only file or directory in /proc/$PID/ to allow this and a bug. That bug will be fixed in the next patch in the series and therefore the test would start failing.
