2024-06-04selftests/bpf: Ignore .llvm.<hash> suffix in kallsyms_find()Yonghong Song
I hit the following failure when running selftests with internal backported upstream kernel: test_ksyms:PASS:kallsyms_fopen 0 nsec test_ksyms:FAIL:ksym_find symbol 'bpf_link_fops' not found #123 ksyms:FAIL In /proc/kallsyms, we have $ cat /proc/kallsyms | grep bpf_link_fops ffffffff829f0cb0 d bpf_link_fops.llvm.12608678492448798416 The CONFIG_LTO_CLANG_THIN is enabled in the kernel which is responsible for bpf_link_fops.llvm.12608678492448798416 symbol name. In prog_tests/ksyms.c we have kallsyms_find("bpf_link_fops", &link_fops_addr) and kallsyms_find() compares "bpf_link_fops" with symbols in /proc/kallsyms in order to find the entry. With bpf_link_fops.llvm.<hash> in /proc/kallsyms, the kallsyms_find() failed. To fix the issue, in kallsyms_find(), if a symbol has suffix .llvm.<hash>, that suffix will be ignored for comparison. This fixed the test failure.

2024-05-30selftests/futex: pass _GNU_SOURCE without a value to the compilerJohn Hubbard
It's slightly better to set _GNU_SOURCE in the source code, but if one must do it via the compiler invocation, then the best way to do so is this: $(CC) -D_GNU_SOURCE= ...because otherwise, if this form is used: $(CC) -D_GNU_SOURCE ...then that leads the compiler to set a value, as if you had passed in: $(CC) -D_GNU_SOURCE=1 That, in turn, leads to warnings under both gcc and clang, like this: futex_requeue_pi.c:20: warning: "_GNU_SOURCE" redefined Fix this by using the "-D_GNU_SOURCE=" form.

2024-05-30netdev: add qstat for csum completeJakub Kicinski
Recent commit 0cfe71f45f42 ("netdev: add queue stats") added a lot of useful stats, but only those immediately needed by virtio. Presumably virtio does not support CHECKSUM_COMPLETE, so statistic for that form of checksumming wasn't included. Other drivers will definitely need it, in fact we expect it to be needed in net-next soon (mlx5). So let's add the definition of the counter for CHECKSUM_COMPLETE to uAPI in net already, so that the counters are in a more natural order (all subsequent counters have not been present in any released kernel, yet).

2024-05-29tracing/selftests: Fix kprobe event name test for .isra. functionsSteven Rostedt (Google)
The kprobe_eventname.tc test checks if a function with .isra. can have a kprobe attached to it. It loops through the kallsyms file for all the functions that have the .isra. name, and checks if it exists in the available_filter_functions file, and if it does, it uses it to attach a kprobe to it. The issue is that kprobes can not attach to functions that are listed more than once in available_filter_functions. With the latest kernel, the function that is found is: rapl_event_update.isra.0 # grep rapl_event_update.isra.0 /sys/kernel/tracing/available_filter_functions rapl_event_update.isra.0 rapl_event_update.isra.0 It is listed twice. This causes the attached kprobe to it to fail which in turn fails the test. Instead of just picking the function function that is found in available_filter_functions, pick the first one that is listed only once in available_filter_functions.
