caa4237a - selftests/bpf: Fix selection of static vs. dynamic LLVM

Mon, 10 Mar 2025 14:51:12 +0000

selftests/bpf: Fix selection of static vs. dynamic LLVMThe Makefile uses the exit code of the `llvm-config --link-static --libs`command to choose between statically-linked and dynamically-linked LLVMs.The stdout and stderr of that command are redirected to /dev/null.To redirect the output the "&>" construction is used, which might not besupported by /bin/sh, which is executed by make for $(shell ...) commands.On such systems the test will fail even if static LLVM is actuallysupported. Replace "&>" by ">/dev/null 2>&1" to fix this.Fixes: 2a9d30fac818 ("selftests/bpf: Support dynamically linking LLVM if static is not available")Signed-off-by: Anton Protopopov Signed-off-by: Andrii Nakryiko Acked-by: Daniel Xu Link: https://lore.kernel.org/bpf/20250310145112.1261241-1-aspsk@isovalent.comSigned-off-by: Alexei Starovoitov List of files: /linux-6.15/tools/testing/selftests/bpf/Makefile

d6212d82 - selftests/bpf: Consolidate kernel modules into common directory

Wed, 04 Dec 2024 13:28:26 +0000

selftests/bpf: Consolidate kernel modules into common directoryThe selftests build four kernel modules which use copy-pasted Makefiletargets. This is a bit messy, and doesn't scale so well when we add moremodules, so let's consolidate these rules into a single rule generatedfor each module name, and move the module sources into a singledirectory.To avoid parallel builds of the different modules stepping on eachother's toes during the 'modpost' phase of the Kbuild 'make modules',the module files should really be a grouped target. However, make onlyadded explicit support for grouped targets in version 4.3, which isnewer than the minimum version supported by the kernel. However, makeimplicitly treats pattern matching rules with multiple targets as agrouped target, so we can work around this by turning the rule into apattern matching target. We do this by replacing '.ko' with '%ko' in thetargets with subst().Signed-off-by: Toke Høiland-Jørgensen Signed-off-by: Andrii Nakryiko Acked-by: Viktor Malik Link: https://lore.kernel.org/bpf/20241204-bpf-selftests-mod-compile-v5-1-b96231134a49@redhat.com List of files: /linux-6.15/tools/testing/selftests/bpf/Makefile
