selftests/bpf: fix broken build, take 2 Merge of 'linux-kselftest-4.11-rc1': 1. Partially removed use of 'test_objs' target, breaking force rebuild of BPFOBJ, introduced in commit d498f8719a09 ("bpf: Rebuild bpf.o for any dependency update"). Update target so dependency on BPFOBJ is restored. 2. Introduced commit 2047f1d8ba28 ("selftests: Fix the .c linking rule") which fixes order of LDLIBS. Commit d02d8986a768 ("bpf: Always test unprivileged programs") added libcap dependency into CFLAGS. Use LDLIBS instead to fix linking of test_verifier. 3. Introduced commit d83c3ba0b926 ("selftests: Fix selftests build to just build, not run tests"). Reordering the Makefile allows us to remove the 'all' target. Tested both: selftests/bpf$ make and selftests$ make TARGETS=bpf on Ubuntu 16.04.2.

bpf: add initial suite for selftests Add a start of a test suite for kernel selftests. This moves test_verifier and test_maps over to tools/testing/selftests/bpf/ along with various code improvements and also adds a script for invoking test_bpf module. The test suite can simply be run via selftest framework, f.e.: # cd tools/testing/selftests/bpf/ # make # make run_tests Both test_verifier and test_maps were kind of misplaced in samples/bpf/ directory and we were looking into adding them to selftests for a while now, so it can be picked up by kbuild bot et al and hopefully also get more exposure and thus new test case additions.

selftests: remove duplicated all and clean target Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt.
