bpf: improve selftests and add tests for meta pointer Add various test_verifier selftests, and a simple xdp/tc functional test that is being attached to veths. Also let new versions of clang use the recently added -mcpu=probe support [1] for the BPF target, so that it can probe the underlying kernel for BPF insn set extensions. We could also just set this options always, where older versions just ignore it and give a note to the user that the -mcpu value is not supported, but given emitting the note cannot be turned off from clang side lets not confuse users running selftests with it, thus fallback to the default generic one when we see that clang doesn't support it. Also allow CPU option to be overridden in the Makefile from command line.

selftests/bpf: fix missing BPF object files After commit afef88e65554 ("selftests/bpf: Store BPF object files with .bpf.o extension"), we should use *.bpf.o instead of *.o. In addition, use the BPF_FILE variable to save the BPF object file name, which can be better identified and modified.

selftests/bpf: Use kselftest skip code for skipped tests There are several test cases in the bpf directory are still using exit 0 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in bpf directory: grep -r "exit 0" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

tools/bpf: fix batch-mode test failure of test_xdp_redirect.sh The tests at tools/testing/selftests/bpf can run in patch mode, e.g., make -C tools/testing/selftests/bpf run_tests With the batch mode, I experimented intermittent test failure of test_xdp_redirect.sh. .... selftests: test_xdp_redirect [PASS] selftests: test_xdp_redirect.sh [PASS] RTNETLINK answers: File exists selftests: test_xdp_meta [FAILED] selftests: test_xdp_meta.sh [FAIL] .... The following illustrates what caused the failure: (1). test_xdp_redirect creates veth pairs (veth1,veth11) and (veth2,veth22), and assign veth11 and veth22 to namespace ns1 and ns2 respectively. (2). at the end of test_xdp_redirect test, ns1 and ns2 are deleted. During this process, the deletion of actual namespace resources, including deletion of veth1{1} and veth2{2}, is put into a workqueue to be processed asynchronously. (3). test_xdp_meta tries to create veth pair (veth1, veth2). The previous veth deletions in step (2) have not finished yet, and veth1 or veth2 may be still valid in the kernel, thus causing the failure. The fix is to explicitly delete the veth pair before test_xdp_redirect exits. Only one end of veth needs deletion as the kernel will delete the other end automatically. Also test_xdp_meta is also fixed in similar manner to avoid future potential issues.
