Here's the fourth try. The "make install" target for the BPF selftests
are missing a bunch of files, which makes the BPF machine flavor fail
(e.g. cpuv4).
This series aims to fix that, but explicitly installing bpftool, all
the BPF programs, and the utilities defined by the TRUNNER_EXTRA_PROGS
for test_progs.
The fact that this series even have a changelog says a lot, but for
those who care:
v4: Added bpftool
v3: Do not use hardcoded file names (Andrii)
v2: Added btf_dump_test_case files
Björn Töpel (3):
selftests/bpf: Remove incorrect object path
selftests/bpf: Make install target copy test_progs extra files
selftests/bpf: Make install target copy bpftool

Add the missing "extra files" dependencies to rsync, called from the install target. Unfortunately, kselftest does not use bash as the default shell, so the globbering is limited. Blindly enabling "SHELL:=/bin/bash" for the Makefile breaks in other places. Workaround by explicitly call "/bin/bash" to expand the file globbing.

FWIW, I fold the two calls in patch 3. Regardless; I'll try to make the whole series more palatable. Björn ^ permalink raw reply [flat|nested] 6+ messages in thread
