[PATCH AUTOSEL 5.15 30/68] selftests/tc-testing: match any qdisc type

by Sasha Levin

From: Li Zhijian <zhijianx.li(a)intel.com> [ Upstream commit bdf1565fe03d29777d24e239163d0d53e4af9ce0 ] We should not always presume all kernels use pfifo_fast as the default qdisc. For example, a fq_codel qdisk could have below output: qdisc fq_codel 0: parent 1:4 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 Reported-by: kernel test robot <lkp(a)intel.com> Suggested-by: Peilin Ye <peilin.ye(a)bytedance.com> Signed-off-by: Li Zhijian <zhijianx.li(a)intel.com> Signed-off-by: David S.

[PATCH bpf-next 0/6] tools/bpf: Enable cross-building with clang

by Jean-Philippe Brucker

Add support for cross-building BPF tools and selftests with clang, by passing LLVM=1 or CC=clang to make, as well as CROSS_COMPILE. A single clang toolchain can generate binaries for multiple architectures, so instead of having prefixes such as aarch64-linux-gnu-gcc, clang uses the -target parameter: `clang -target aarch64-linux-gnu'. Patch 1 adds the parameter in Makefile.include so tools can easily support this. Patch 2 prepares for the libbpf change from patch 3 (keep building resolve_btfids's libbpf in the host arch, when cross-building the kernel with clang). Patches 3-6 enable cross-building BPF tools with clang.

[PATCH] kselftest: Fix vdso_test_time to pass on skips

by Cristian Marussi

When a vDSO symbol is not found, all the testcases in vdso_test_abi usually report a SKIP, which, in turn, is reported back to Kselftest as a PASS. Testcase vdso_test_time, instead, reporting a SKIP, causes the whole set of tests within vdso_test_abi to be considered FAIL when symbol is not found. Fix it reporting a PASS when vdso_test_time cannot find the vdso symbol.
