2023-09-25selftests/bpf: Add tests for ring__avail_data_sizeMartin Kelly
Add test for the new API ring__avail_data_size. Signed-off-by: Martin Kelly <martin.kelly@crowdstrike.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20230925215045.2375758-9-martin.kelly@crowdstrike.com
2023-09-25libbpf: Add ring__avail_data_sizeMartin Kelly
Add ring__avail_data_size for querying the currently available data in the ringbuffer, similar to the BPF_RB_AVAIL_DATA flag in bpf_ringbuf_query. This is racy during ongoing operations but is still useful for overall information on how a ringbuffer is behaving.

2023-09-25libbpf: Switch rings to array of pointersMartin Kelly
Switch rb->rings to be an array of pointers instead of a contiguous block. This allows for each ring pointer to be stable after ring_buffer__add is called, which allows us to expose struct ring * to the user without gotchas. Without this change, the realloc in ring_buffer__add could invalidate a struct ring *, making it unsafe to give to the user.

2023-09-25libbpf: Refactor cleanup in ring_buffer__addMartin Kelly
Refactor the cleanup code in ring_buffer__add to use a unified err_out label. This reduces code duplication, as well as plugging a potential leak if mmap_sz != (__u64)(size_t)mmap_sz (currently this would miss unmapping tmp because ringbuf_unmap_ring isn't called).

2023-09-24rcutorture: Copy out ftrace into its own console fileJoel Fernandes (Google)
When debugging, it can be difficult to quickly find the ftrace dump within the console log, which in turn makes it difficult to process it independent of the rest of the console output. This commit therefore copies the contents of the buffers into its own file to make it easier to locate and process the ftrace dump. The original ftrace dump is still available in the console log in cases because it can be more convenient to process it in situ, for example, for scripts that process console output as well as ftrace-dump data. Also handle the case of multiple ftrace dumps potentially showing up in the log. Example for a file like [1], it will extract as [2].

2023-09-22selftests/bpf: Add tests for symbol versioning for uprobeHengqi Chen
This exercises the newly added dynsym symbol versioning logics. Now we accept symbols in form of func, func@LIB_VERSION or func@@LIB_VERSION. The test rely on liburandom_read.so.

For `urandlib_api_sameoffset`, there are also two symbols in the .so, but both are at the same offset and essentially they refer to the same function so no conflict.

2023-09-22libbpf: Support symbol versioning for uprobeHengqi Chen
In current implementation, we assume that symbol found in .dynsym section would have a version suffix and use it to compare with symbol user supplied. According to the spec ([0]), this assumption is incorrect, the version info of dynamic symbols are stored in .gnu.version and .gnu.version_d sections of ELF objects. For example: $ nm -D /lib/x86_64-linux-gnu/libc.so.6 | grep rwlock_wrlock 000000000009b1a0 T __pthread_rwlock_wrlock@GLIBC_2.2.5 000000000009b1a0 T pthread_rwlock_wrlock@@GLIBC_2.34 000000000009b1a0 T pthread_rwlock_wrlock@GLIBC_2.2.5 $ readelf -W --dyn-syms /lib/x86_64-linux-gnu/libc.so.6 | grep rwlock_wrlock 706: 000000000009b1a0 878 FUNC GLOBAL DEFAULT 15 __pthread_rwlock_wrlock@GLIBC_2.2.5 2568: 000000000009b1a0 878 FUNC GLOBAL DEFAULT 15 pthread_rwlock_wrlock@@GLIBC_2.34 2571: 000000000009b1a0 878 FUNC GLOBAL DEFAULT 15 pthread_rwlock_wrlock@GLIBC_2.2.5 In this case, specify pthread_rwlock_wrlock@@GLIBC_2.34 or pthread_rwlock_wrlock@GLIBC_2.2.5 in bpf_uprobe_opts::func_name won't work. Because the qualified name does NOT match `pthread_rwlock_wrlock` (without version suffix) in .dynsym sections. This commit implements the symbol versioning for dynsym and allows user to specify symbol in the following forms: - func - func@LIB_VERSION - func@@LIB_VERSION In case of symbol conflicts, error out and users should resolve it by specifying a qualified name.

2023-09-22libbpf: Resolve symbol conflicts at the same offset for uprobeHengqi Chen
Dynamic symbols in shared library may have the same name, for example: $ nm -D /lib/x86_64-linux-gnu/libc.so.6 | grep rwlock_wrlock 000000000009b1a0 T __pthread_rwlock_wrlock@GLIBC_2.2.5 000000000009b1a0 T pthread_rwlock_wrlock@@GLIBC_2.34 000000000009b1a0 T pthread_rwlock_wrlock@GLIBC_2.2.5 $ readelf -W --dyn-syms /lib/x86_64-linux-gnu/libc.so.6 | grep rwlock_wrlock 706: 000000000009b1a0 878 FUNC GLOBAL DEFAULT 15 __pthread_rwlock_wrlock@GLIBC_2.2.5 2568: 000000000009b1a0 878 FUNC GLOBAL DEFAULT 15 pthread_rwlock_wrlock@@GLIBC_2.34 2571: 000000000009b1a0 878 FUNC GLOBAL DEFAULT 15 pthread_rwlock_wrlock@GLIBC_2.2.5 Currently, users can't attach a uprobe to pthread_rwlock_wrlock because there are two symbols named pthread_rwlock_wrlock and both are global bind. And libbpf considers it as a conflict. Since both of them are at the same offset we could accept one of them harmlessly. Note that we already does this in elf_resolve_syms_offsets.

2023-09-22rtla/timerlat: Do not stop user-space if a cpu is offlineDaniel Bristot de Oliveira
If no CPU list is passed, timerlat in user-space will dispatch one thread per sysconf(_SC_NPROCESSORS_CONF). However, not all CPU might be available, for instance, if HT is disabled. Currently, rtla timerlat is stopping the session if an user-space thread cannot set affinity to a CPU, or if a running user-space thread is killed. However, this is too restrictive. So, reduce the error to a debug message, and rtla timerlat run as long as there is at least one user-space thread alive.

2023-09-22selftests/powerpc: Fix emit_tests to work with run_kselftest.shMichael Ellerman
In order to use run_kselftest.sh the list of tests must be emitted to populate kselftest-list.txt. The powerpc Makefile is written to use EMIT_TESTS. But support for EMIT_TESTS was dropped in commit d4e59a536f50 ("selftests: Use runner.sh for emit targets"). Although prior to that commit a548de0fe8e1 ("selftests: lib.mk: add test execute bit check to EMIT_TESTS") had already broken run_kselftest.sh for powerpc due to the executable check using the wrong path. It can be fixed by replacing the EMIT_TESTS definitions with actual emit_tests rules in the powerpc Makefiles. This makes run_kselftest.sh able to run powerpc tests: $ cd linux $ export ARCH=powerpc $ export CROSS_COMPILE=powerpc64le-linux-gnu- $ make headers $ make -j -C tools/testing/selftests install $ grep -c "^powerpc" tools/testing/selftests/kselftest_install/kselftest-list.txt 182 Fixes: d4e59a536f50 ("selftests: Use runner.sh for emit targets") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20230921072623.828772-1-mpe@ellerman.id.au

2023-09-21selftests/bpf: Unmount the cgroup2 work directoryIlya Leoshkevich
test_progs -t bind_perm,bpf_obj_pinning/mounted-str-rel fails when the selftests directory is mounted under /mnt, which is a reasonable thing to do when sharing the selftests residing on the host with a virtual machine, e.g., using 9p. The reason is that cgroup2 is mounted at /mnt and not unmounted, causing subsequent tests that need to access the selftests directory to fail. Fix by unmounting it. The kernel maintains a mount stack, so this reveals what was mounted there before. Introduce cgroup_workdir_mounted in order to maintain idempotency.

2023-09-21RISC-V: selftests: Add CBO testsAndrew Jones
Add hwprobe test for Zicboz and its block size. Also, when Zicboz is present, test that cbo.zero may be issued and works. Additionally provide a command line option that enables testing that the Zicbom instructions cause SIGILL and also that cbo.zero causes SIGILL when Zicboz it's not present. The SIGILL tests require "opt-in" with a command line option because the RISC-V ISA does not require unimplemented standard opcodes to issue illegal-instruction exceptions (but hopefully most platforms do). Pinning the test to a subset of cpus with taskset will also restrict the hwprobe calls to that set.

Returning (exiting with) negative exit codes isn't user friendly, because the user must output the exit code with the shell, convert it from its unsigned 8-bit value back to the negative value, and then look up where that comes from in the code (which may be multiple places). Use the kselftests TAP interface, instead.

Currently the AIA ONE_REG registers are reported by get-reg-list as new registers for various vcpu_reg_list configs whenever Ssaia is available on the host because Ssaia extension can only be disabled by Smstateen extension which is not always available. To tackle this, we should filter-out AIA ONE_REG registers only when Ssaia can't be disabled for a VCPU.

Same set of ISA_EXT registers are not present on all host because ISA_EXT registers are visible to the KVM user space based on the ISA extensions available on the host. Also, disabling an ISA extension using corresponding ISA_EXT register does not affect the visibility of the ISA_EXT register itself. Based on the above, we should filter-out all ISA_EXT registers.

2023-09-20kselftest: Add new test for detecting unprobed Devicetree devicesNícolas F. R. A. Prado
Introduce a new kselftest to detect devices that were declared in the Devicetree, and are expected to be probed by a driver, but weren't. The test uses two lists: a list of compatibles that can match a Devicetree device to a driver, and a list of compatibles that should be ignored. The first is automatically generated by the dt-extract-compatibles script, and is run as part of building this test. The list of compatibles to ignore is a hand-crafted list to capture the few exceptions of compatibles that are expected to match a driver but not be bound to it. Signed-off-by: Nícolas F. R. A.

When parsing the configs, keep track of card configurations that match the current system but haven't matched any card, and report those as test failures as they represent that a card which was expected to be present on the system is missing. This allows the configuration files to not only be used to detect missing PCM devices (which is currently possible) but also that the soundcard hasn't been registered at all.

2023-09-19selftests: link libasan statically for tests with -fsanitize=addressRyan Roberts
When dynamically linking, Address Sanitizer requires its library to be the first one to be loaded; this is apparently to ensure that every call to malloc is intercepted. If using LD_PRELOAD, those listed libraries will be loaded before the libraries listed in the program's ELF and will therefore violate this requirement, leading to the below failure and output from ASan. commit 58e2847ad2e6 ("selftests: line buffer test program's stdout") modified the kselftest runner to force line buffering by forcing the test programs to run through `stdbuf`. It turns out that stdbuf implements line buffering by injecting a library via LD_PRELOAD. Therefore selftests that use ASan started failing. Fix this by statically linking libasan in the affected test programs, using the `-static-libasan` option. Note this is already the default for Clang, but not got GCC. Test output sample for failing case: TAP version 13 1..3 # timeout set to 300 # selftests: openat2: openat2_test # ==4052==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. not ok 1 selftests: openat2: openat2_test # exit=1 # timeout set to 300 # selftests: openat2: resolve_test # ==4070==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. not ok 2 selftests: openat2: resolve_test # exit=1 Link: https://lkml.kernel.org/r/20230912135048.1755771-1-ryan.roberts@arm.com Signed-off-by: Ryan Roberts <ryan.roberts@arm.com> Fixes: 58e2847ad2e6 ("selftests: line buffer test program's stdout") Reported-by: kernel test robot <oliver.sang@intel.com> Closes: https://lore.kernel.org/oe-lkp/202309121342.97e2f008-oliver.sang@intel.com Cc: David Hildenbrand <david@redhat.com> Cc: Florent Revest <revest@chromium.org> Cc: Jérôme Glisse <jglisse@redhat.com> Cc: John Hubbard <jhubbard@nvidia.com> Cc: Mark Brown <broonie@kernel.org> Cc: Peter Xu <peterx@redhat.com> Cc: Shuah Khan <shuah@kernel.org> Cc: Tom Rix <trix@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
