2020-01-15selftests: mlxsw: qos_mc_aware: Fix mausezahn invocationPetr Machata
Mausezahn does not recognize "own" as a keyword on source IP address. As a result, the MC stream is not running at all, and therefore no UC degradation can be observed even in principle. Fix the invocation, and tighten the test: due to the minimum shaper configured at the MC TCs, we always expect about 20% degradation. Fail the test if it is lower.

Sync msr-index.h to pull in recent renames of the IA32_FEATURE_CONTROL MSR definitions. Update KVM's VMX selftest and turbostat accordingly. Keep the full name in turbostat's output to avoid breaking someone's workflow, e.g. if a script is looking for the full name. While using the renamed defines is by no means necessary, do the sync now to avoid leaving a landmine that will get stepped on the next time msr-index.h needs to be refreshed for some other reason.

2020-01-13selftests, kvm: Replace manual MSR defs with common msr-index.hSean Christopherson
The kernel's version of msr-index.h was pulled wholesale into tools by commit 444e2ff34df8 ("tools arch x86: Grab a copy of the file containing the MSR numbers"), Use the common msr-index.h instead of manually redefining everything in a KVM-only header. Note, a few MSR-related definitions remain in processor.h because they are not covered by msr-index.h, including the awesomely named APIC_BASE_MSR, which refers to starting index of the x2APIC MSRs, not the actual MSR_IA32_APICBASE, which *is* defined by msr-index.h.

2020-01-10selftests/bpf: Add BPF_PROG, BPF_KPROBE, and BPF_KRETPROBE macrosAndrii Nakryiko
Streamline BPF_TRACE_x macro by moving out return type and section attribute definition out of macro itself. That makes those function look in source code similar to other BPF programs. Additionally, simplify its usage by determining number of arguments automatically (so just single BPF_TRACE vs a family of BPF_TRACE_1, BPF_TRACE_2, etc). Also, allow more natural function argument syntax without commas inbetween argument type and name. Given this helper is useful not only for tracing tp_btf/fenty/fexit programs, but could be used for LSM programs and others following the same pattern, rename BPF_TRACE macro into more generic BPF_PROG. Existing BPF_TRACE_x usages in selftests are converted to new BPF_PROG macro. Following the same pattern, define BPF_KPROBE and BPF_KRETPROBE macros for nicer usage of kprobe/kretprobe arguments, respectively. BPF_KRETPROBE, adopts same convention used by fexit programs, that last defined argument is probed function's return result. v4->v5: - fix test_overhead test (__set_task_comm is void) (Alexei); v3->v4: - rebased and fixed one more BPF_TRACE_x occurence (Alexei); v2->v3: - rename to shorter and as generic BPF_PROG (Alexei); v1->v2: - verified GCC handles pragmas as expected; - added descriptions to macros; - converted new STRUCT_OPS selftest to BPF_HANDLER (worked as expected); - added original context as 'ctx' parameter, for cases where it has to be passed into BPF helpers. This might cause an accidental naming collision, unfortunately, but at least it's easy to work around. Fortunately, this situation produces quite legible compilation error: progs/bpf_dctcp.c:46:6: error: redefinition of 'ctx' with a different type: 'int' vs 'unsigned long long *' int ctx = 123; ^ progs/bpf_dctcp.c:42:6: note: previous definition is here void BPF_HANDLER(dctcp_init, struct sock *sk) ^ ./bpf_trace_helpers.h:58:32: note: expanded from macro 'BPF_HANDLER' ____##name(unsigned long long *ctx, ##args) Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Martin KaFai Lau <kafai@fb.com> Link: https://lore.kernel.org/bpf/20200110211634.1614739-1-andriin@fb.com

2020-01-09selftests/bpf: Ensure bpf_helper_defs.h are taken from selftests dirAndrii Nakryiko
Reorder includes search path to ensure $(OUTPUT) and $(CURDIR) go before libbpf's directory. Also fix bpf_helpers.h to include bpf_helper_defs.h in such a way as to leverage includes search path. This allows selftests to not use libbpf's local and potentially stale bpf_helper_defs.h. It's important because selftests/bpf's Makefile only re-generates bpf_helper_defs.h in seltests' output directory, not the one in libbpf's directory.

2020-01-09selftests/bpf: Restore original comm in test_overheadStanislav Fomichev
test_overhead changes task comm in order to estimate BPF trampoline overhead but never sets the comm back to the original one. We have the tests (like core_reloc.c) that have 'test_progs' as hard-coded expected comm, so let's try to preserve the original comm. Currently, everything works because the order of execution is: first core_recloc, then test_overhead; but let's make it a bit future-proof. Other related changes: use 'test_overhead' as new comm instead of 'test' to make it easy to debug and drop '\n' at the end.

2020-01-06fcnal-test: Fix vrf argument in local tcp testsDavid Ahern
The recent MD5 tests added duplicate configuration in the default VRF. This change exposed a bug in existing tests designed to verify no connection when client and server are not in the same domain. The server should be running bound to the vrf device with the client run in the default VRF (the -2 option is meant for validating connection data). Fix the option for both tests. While technically this is a bug in previous releases, the tests are properly failing since the default VRF does not have any routing configuration so there really is no need to backport to prior releases.

2020-01-06selftests: fix build behaviour on targets' failuresCristian Marussi
Currently, when some of the KSFT subsystems fails to build, the toplevel KSFT Makefile just keeps carrying on with the build process. This behaviour is expected and desirable especially in the context of a CI system running KSelfTest, since it is not always easy to guarantee that the most recent and esoteric dependencies are respected across all KSFT TARGETS in a timely manner. Unfortunately, as of now, this holds true only if the very last of the built subsystems could have been successfully compiled: if the last of those subsystem instead failed to build, such failure is taken as the whole outcome of the Makefile target and the complete build/install process halts even though many other preceding subsytems were in fact already built successfully. Fix the KSFT Makefile behaviour related to all/install targets in order to fail as a whole only when the all/install targets have failed for all of the requested TARGETS, while succeeding when at least one of TARGETS has been successfully built.

2020-01-06selftests/powerpc: Add a test of bad (out-of-range) accessesMichael Ellerman
Userspace isn't allowed to access certain address ranges, make sure we actually test that to at least some degree. This would have caught the recent bug where the SLB fault handler was incorrectly called on an out-of-range access when using the Radix MMU. It also would have caught the bug we had in get_region_id() where we were inserting SLB entries for bad addresses.

2020-01-05wireguard: selftests: remove ancient kernel compatibility codeJason A. Donenfeld
Quite a bit of the test suite was designed to work with ancient kernels. Thankfully we no longer have to deal with this. This commit updates things that we can finally update and removes things that we can finally remove, to avoid the build-up of the last several years as a result of having to support ancient kernels. We can finally rely on suppress_ prefixlength being available. On the build side of things, the no-PIE hack is no longer required, and we can bump some of the tools, repair our m68k and i686-kvm support, and get better coverage of the static branches used in the crypto lib and in udp_tunnel.
