[PATCH bpf v2 4/4] bpf_trace: pass array of u64 values in kprobe_multi.addrs

by Eugene Syromiatnikov

With the interface as defined, it is impossible to pass 64-bit kernel addresses from a 32-bit userspace process in BPF_LINK_TYPE_KPROBE_MULTI, which severly limits the useability of the interface, change the ABI to accept an array of u64 values instead of (kernel? user?) longs. Interestingly, the rest of the libbpf infrastructure uses 64-bit values for kallsyms addresses already, so this patch also eliminates the sym_addr cast in tools/lib/bpf/libbpf.c:resolve_kprobe_multi_cb().

[PATCH bpf v2 3/4] bpf_trace: handle compat in kprobe_multi_resolve_syms

by Eugene Syromiatnikov

For compat processes, userspace pointer size is different. Since the copied array is iterated anyway, the simplest fix seems to be copy the user-supplied array as-is and the iterate as an array of native or compat pointers, depending on the in_compat_syscall() value.

[PATCH bpf v2 0/4] Fix 32-bit arch and compat support for the kprobe_multi attach type

by Eugene Syromiatnikov

As suggested in [1], the kprobe_multi interface is to be fixed for 32-bit architectures and compat, rather then disabled. As it turned out, there are a couple of additional problems that are to be addressed: - the absence of size overflow checks, leading to possible out-of-bounds writes (addressed by the first patch); - the assumption that long has the same size as u64, which would make cookies arrays size calculation incorrect on 32-bit architectures (addressed by the second patch); - the addrs array passing API, that is incompatible with compat and has to be changed (addressed in the fourth patch): those are kernel addresses and not user ones (as was incorrectly stated in [2]); this change is only semantical for 64-bit user/kernelspace, so it shouldn't impact ABI there, at least.

[PATCH] kunit: fix executor OOM error handling logic on non-UML

by Daniel Latypov

The existing logic happens to work fine on UML, but is not correct when running on other arches. 1. We didn't initialize `int err`, and kunit_filter_suites() doesn't explicitly set it to 0 on success. So we had false "failures". Note: it doesn't happen on UML, causing this to get overlooked. 2. If we error out, we do not call kunit_handle_shutdown(). This makes kunit.py timeout when using a non-UML arch, since the QEMU process doesn't ever exit.

[PATCH] selftests: alsa: Better error messages

by Siddh Raman Pant

This allows for potentially better machine-parsing due to an expected / fixed format. Also because of eyecandy reasons. Whenever possible, errors will start with the name of the offending card/control, separated by the error with colons. Whenever there is a description of an error given, the generated error string from snd_strerror will be (mostly) enclosed in parentheses at the end. Clarity of error messages have been (hopefully) improved.

[PATCH] kselftest/arm64: bti: force static linking

by Andre Przywara

The "bti" selftests are built with -nostdlib, which apparently automatically creates a statically linked binary, which is what we want and need for BTI (to avoid interactions with the dynamic linker). However this is not true when building a PIE binary, which some toolchains (Ubuntu) configure as the default. When compiling btitest with such a toolchain, it will create a dynamically linked binary, which will probably fail some tests, as the dynamic linker might not support BTI: =================== TAP version 13 1..18 not ok 1 nohint_func/call_using_br_x0 not ok 2 nohint_func/call_using_br_x16 not ok 3 nohint_func/call_using_blr .... =================== To make sure we create static binaries, add an explicit -static on the linker command line. This forces static linking even if the toolchain defaults to PIE builds, and fixes btitest runs on BTI enabled machines.
