Subject: [PATCH bpf-next v3 1/2] selftests/bpf: Remove incorrect object path

From: Björn Töpel <[email protected]>

The glob path, progs/*.bpf.o, is no longer a correct path. The BPF
object files reside in the top directory, or in the per-flavor
directory (e.g. cpuv4).

Remove the incorrect object path.

Subject: [PATCH bpf-next v3 2/2] selftests/bpf: Make install target copy test_progs extra files

From: Björn Töpel <[email protected]>

Currently, "make install" does not install the required test_progs
"extra files" (e.g. kernel modules, helper shell scripts, etc.) for
the BPF machine flavors (e.g. cpuv4).

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.

Argh! Bad commit. EXTRA_FILE_GLOB should be EXTRA_FILES_GLOB. :-(

LMK if you can fix it up, or if you want me to resubmit.

..and bpftool is missing.

I'll spin a v4. :-(
