2021-10-27selftests/powerpc: Use date instead of EPOCHSECONDS in mitigation-patching.shRussell Currey1-2/+2
The EPOCHSECONDS environment variable was added in bash 5.0 (released 2019). Some distributions of the "stable" and "long-term" variety ship older versions of bash than this, so swap to using the date command instead. "%s" was added to coreutils `date` in 1993 so we should be good, but who knows, it is a GNU extension and not part of the POSIX spec for `date`.

2021-10-26selftests/ftrace: Stop tracing while reading the trace file by defaultMasami Hiramatsu2-1/+13
Stop tracing while reading the trace file by default, to prevent the test results while checking it and to avoid taking a long time to check the result. If there is any testcase which wants to test the tracing while reading the trace file, please override this setting inside the test case. This also recovers the pause-on-trace when clean it up.

2021-10-25selftests/bpf: Split out bpf_verif_scale selftests into multiple testsAndrii Nakryiko1-68/+152
Instead of using subtests in bpf_verif_scale selftest, turn each scale sub-test into its own test. Each subtest is compltely independent and just reuses a bit of common test running logic, so the conversion is trivial. For convenience, keep all of BPF verifier scale tests in one file. This conversion shaves off a significant amount of time when running test_progs in parallel mode. E.g., just running scale tests (-t verif_scale): BEFORE ====== Summary: 24/0 PASSED, 0 SKIPPED, 0 FAILED real 0m22.894s user 0m0.012s sys 0m22.797s AFTER ===== Summary: 24/0 PASSED, 0 SKIPPED, 0 FAILED real 0m12.044s user 0m0.024s sys 0m27.869s Ten second saving right there. test_progs -j is not yet ready to be turned on by default, unfortunately, and some tests fail almost every time, but this is a good improvement nevertheless. Ignoring few failures, here is sequential vs parallel run times when running all tests now: SEQUENTIAL ========== Summary: 206/953 PASSED, 4 SKIPPED, 0 FAILED real 1m5.625s user 0m4.211s sys 0m31.650s PARALLEL ======== Summary: 204/952 PASSED, 4 SKIPPED, 2 FAILED real 0m35.550s user 0m4.998s sys 0m39.890s Signed-off-by: Andrii Nakryiko <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]

kunit.py currently crashes and fails to parse kernel output if it's not fully valid utf-8. This can come from memory corruption or just inadvertently printing out binary data as strings. E.g. adding this line into a kunit test pr_info("\x80") will cause this exception UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 1961: invalid start byte We can tell Python how to handle errors, see https://docs.python.org/3/library/codecs.html#error-handlers Unfortunately, it doesn't seem like there's a way to specify this in just one location, so we need to repeat ourselves quite a bit. Specify `errors='backslashreplace'` so we instead: * print out the offending byte as '\x80' * try and continue parsing the output. * as long as the TAP lines themselves are valid, we're fine.

The nexthop objects tests configure dummy reachable neighbours so that the nexthops will have a MAC address and be programmed to the device. Since these are dummy reachable neighbours, they can be transitioned by the kernel to a failed state if they are around for too long. This can happen, for example, if the "TIMEOUT" variable is configured with a too high value. Make the tests more robust by configuring the neighbours as permanent, so that the tests do not depend on the configured timeout value.

2021-10-25selftests: mlxsw: Add helpers for skipping selftestsPetr Machata8-24/+81
A number of mlxsw-specific selftests currently detect whether they are run on a compatible machine, and bail out silently when not. These tests are however done in a somewhat impenetrable manner by directly comparing PCI IDs against a blacklist or a whitelist, and bailing out silently if the machine is not compatible. Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying the supported machines in a human-readable manner. If the current machine is incompatible, the helper emits a SKIP message and returns an error code, based on which the caller can gracefully bail out in a suitable way. This allows a more readable conditions such as: mlxsw_only_on_spectrum 2+ || return Convert all existing open-coded guards to the new helper. Also add two new guards to do_mark_test() and do_drop_test(), which are supported only on Spectrum-2+, but the corresponding check was not there.

2021-10-22KVM: selftests: Fix nested SVM tests when built with clangJim Mattson1-1/+13
Though gcc conveniently compiles a simple memset to "rep stos," clang prefers to call the libc version of memset. If a test is dynamically linked, the libc memset isn't available in L1 (nor is the PLT or the GOT, for that matter). Even if the test is statically linked, the libc memset may choose to use some CPU features, like AVX, which may not be enabled in L1. Note that __builtin_memset doesn't solve the problem, because (a) the compiler is free to call memset anyway, and (b) __builtin_memset may also choose to use features like AVX, which may not be available in L1. To avoid a myriad of problems, use an explicit "rep stos" to clear the VMCB in generic_svm_setup(), which is called both from L0 and L1.

2021-10-22KVM: selftests: set CPUID before setting sregs in vcpu creationMichael Roth2-4/+2
Recent kernels have checks to ensure the GPA values in special-purpose registers like CR3 are within the maximum physical address range and don't overlap with anything in the upper/reserved range. In the case of SEV kselftest guests booting directly into 64-bit mode, CR3 needs to be initialized to the GPA of the page table root, with the encryption bit set. The kernel accounts for this encryption bit by removing it from reserved bit range when the guest advertises the bit position via KVM_SET_CPUID*, but kselftests currently call KVM_SET_SREGS as part of vm_vcpu_add_default(), before KVM_SET_CPUID*. As a result, KVM_SET_SREGS will return an error in these cases. Address this by moving vcpu_set_cpuid() (which calls KVM_SET_CPUID*) ahead of vcpu_setup() (which calls KVM_SET_SREGS). While there, address a typo in the assertion that triggers when KVM_SET_SREGS fails.

2021-10-21selftests/bpf: Use nanosleep tracepoint in perf buffer testJiri Olsa1-1/+1
The perf buffer tests triggers trace with nanosleep syscall, but monitors all syscalls, which results in lot of data in the buffer and makes it harder to debug. Let's lower the trace traffic and monitor just nanosleep syscall.

The perf buffer test calls perf_buffer__consume_buffer for all 'possible' cpus, but the library holds only 'online' cpu buffers and perf_buffer__consume_buffer returns them based on index. Adding extra (online) index to keep track of online buffers, we need the original (possible) index to trigger trace on proper cpu.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS fixes for net The following patchset contains Netfilter fixes for net: 1) Crash due to missing initialization of timer data in xt_IDLETIMER, from Juhee Kang. 2) NF_CONNTRACK_SECMARK should be bool in Kconfig, from Vegard Nossum. 3) Skip netdev events on netns removal, from Florian Westphal. 4) Add testcase to show port shadowing via UDP, also from Florian. 5) Remove pr_debug() code in ip6t_rt, this fixes a crash due to unsafe access to non-linear skbuff, from Xin Long. 6) Make net/ipv4/vs/debug_level read-only from non-init netns, from Antoine Tenart. 7) Remove bogus invocation to bash in selftests/netfilter/nft_flowtable.sh also from Florian. ==================== Signed-off-by: David S.
