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.

bpf: Preserve const register type on const OR alu ops Occasionally, clang (e.g. version 3.8.1) translates a sum between two constant operands using a BPF_OR instead of a BPF_ADD. The verifier is currently not handling this scenario, and the destination register type becomes UNKNOWN_VALUE even if it's still storing a constant. As a result, the destination register cannot be used as argument to a helper function expecting a ARG_CONST_STACK_*, limiting some use cases. Modify the verifier to handle this case, and add a few tests to make sure all combinations are supported, and stack boundaries are still verified even with BPF_OR.

bpf: Add tests for the lpm trie map The first part of this program runs randomized tests against the lpm-bpf-map. It implements a "Trivial Longest Prefix Match" (tlpm) based on simple, linear, single linked lists. The implementation should be pretty straightforward. Based on tlpm, this inserts randomized data into bpf-lpm-maps and verifies the trie-based bpf-map implementation behaves the same way as tlpm. The second part uses 'real world' IPv4 and IPv6 addresses and tests the trie with those.

tools/bpf: permit selftests/bpf to be built in a different directory Fix a couple of issues at tools/testing/selftests/bpf/Makefile so the following command make -C tools/testing/selftests/bpf OUTPUT=/home/yhs/tmp can put the built results into a different directory. Also add the built binary test_tcpbpf_user in the .gitignore file. Fixes: 6882804c916b ("selftests/bpf: add a test for overlapping packet range checks") Fixes: 9d1f15941967 ("bpf: move cgroup_helpers from samples/bpf/ to tools/testing/selftesting/bpf/") Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
