2018-03-09tools: bpf: silence make by not deleting intermediate fileJiri Benc1-1/+1
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 <jbenc@redhat.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

2018-03-09tools: bpf: consistent make bpf_installJiri Benc1-4/+6
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.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-03-03 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Extend bpftool to build up CFG information of eBPF programs and add an option to dump this in DOT format such that this can later be used with DOT graphic tools (xdot, graphviz, etc) to visualize it. Part of the analysis performed is sub-program detection and basic-block partitioning, from Jiong. 2) Multiple enhancements for bpftool's batch mode, more specifically the parser now understands comments (#), continuation lines (\), and arguments enclosed between quotes. Also, allow to read from stdin via '-' as input file, all from Quentin. 3) Improve BPF kselftests by i) unifying the rlimit handling into a helper that is then used by all tests, and ii) add support for testing tail calls to test_verifier plus add tests covering all corner cases. The latter is especially useful for testing JITs, from Daniel. 4) Remove x64 JIT's bpf_flush_icache() since flush_icache_range() is a noop on x64, from Daniel. 5) Fix one more occasion in BPF samples where we do not detach the BPF program from the cgroup after completion, from Prashant. ==================== Signed-off-by: David S.
