tools: bpf: remove feature detection output

2018-03-16T08:23:46Z

bpf tools use feature detection for libbfd dependency, clean up the output files on make clean. Signed-off-by: Jakub Kicinski Signed-off-by: Daniel Borkmann

tools: bpf: cleanup PHONY target

2018-03-16T08:23:31Z

There is no FORCE target in the Makefile and some of the PHONY targets are missing, update the list. Signed-off-by: Jakub Kicinski Signed-off-by: Daniel Borkmann

tools: bpf: silence make by not deleting intermediate file

2018-03-09T09:22:59Z

Even in quiet mode, make finishes with rm tools/bpf/bpf_exp.lex.c That's because it considers the file to be intermediate. Silence that by mentioning the lex.c file instead of the lex.o file; the dependency still stays. Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

tools: bpf: respect quiet/verbose build

2018-03-09T09:22:59Z

Default to quiet build, with V=1 enabling verbose build as is usual. Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

tools: bpf: call descend in Makefile

2018-03-09T09:22:59Z

Use the descend macro to properly propagate $(subdir) to bpftool. Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

tools: bpf: make install should build first

2018-03-09T09:22:59Z

Make the 'install' target depend on the 'all' target to build the binaries first. Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

tools: bpf: consistent make bpf_install

2018-03-09T09:22:59Z

Currently, make bpf_install in tools/ does not respect DESTDIR. Moreover, it installs to /usr/bin/ unconditionally. Let it respect DESTDIR and allow prefix to be specified. Also, to be more consistent with bpftool and with the usual customs, default the prefix to /usr/local instead of /usr. Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

tools: bpf: respect output directory during build

2018-03-09T09:22:59Z

Currently, the programs under tools/bpf (with the notable exception of bpftool) do not respect the output directory (make O=dir). Fix that. Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

tools/bpftool: fix bpftool build with bintutils >= 2.9

2017-12-30T00:07:36Z

Bpftool build is broken with binutils version 2.29 and later. The cause is commit 003ca0fd2286 ("Refactor disassembler selection") in the binutils repo, which changed the disassembler() function signature. Fix this by adding a new "feature" to the tools/build/features infrastructure and make it responsible for decision which disassembler() function signature to use.
