The system for "Auto-detecting system features" located under tools/build/ are (currently) used by perf, libbpf and bpftool. It can contain stalled feature detection files, which are not cleaned up by libbpf and bpftool on make clean (side-note: perf tool is correct). Fix this by making the users invoke the make clean target. Some details about the changes. The libbpf Makefile already had a clean-config target (which seems to be copy-pasted from perf), but this target was not "connected" (a make dependency) to clean target. Choose not to rename target as someone might be using it. Did change the output from "CLEAN config" to "CLEAN feature-detect", to make it more clear what happens. This is related to the complaint and troubleshooting in the following link: https://lore.kernel.org/lkml/20200818122007.2d1cfe2d@carbon/ Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Jiri Olsa <jolsa@redhat.com> Link: https://lore.kernel.org/lkml/20200818122007.2d1cfe2d@carbon/ Link: https://lore.kernel.org/bpf/159851841661.1072907.13770213104521805592.stgit@firesoul |
