2021-11-26KVM: selftests: Make sure kvm_create_max_vcpus test won't hit RLIMIT_NOFILEVitaly Kuznetsov
With the elevated 'KVM_CAP_MAX_VCPUS' value kvm_create_max_vcpus test may hit RLIMIT_NOFILE limits: # ./kvm_create_max_vcpus KVM_CAP_MAX_VCPU_ID: 4096 KVM_CAP_MAX_VCPUS: 1024 Testing creating 1024 vCPUs, with IDs 0...1023. /dev/kvm not available (errno: 24), skipping test Adjust RLIMIT_NOFILE limits to make sure KVM_CAP_MAX_VCPUS fds can be opened. Note, raising hard limit ('rlim_max') requires CAP_SYS_RESOURCE capability which is generally not needed to run kvm selftests (but without raising the limit the test is doomed to fail anyway).

2021-11-26KVM: selftests: Avoid KVM_SET_CPUID2 after KVM_RUN in hyperv_features testVitaly Kuznetsov
hyperv_features's sole purpose is to test access to various Hyper-V MSRs and hypercalls with different CPUID data. As KVM_SET_CPUID2 after KVM_RUN is deprecated and soon-to-be forbidden, avoid it by re-creating test VM for each sub-test.

2021-11-25selftests/bpf: Mix legacy (maps) and modern (vars) BPF in one testAndrii Nakryiko
Add selftest that combines two BPF programs within single BPF object file such that one of the programs is using global variables, but can be skipped at runtime on old kernels that don't support global data. Another BPF program is written with the goal to be runnable on very old kernels and only relies on explicitly accessed BPF maps. Such test, run against old kernels (e.g., libbpf CI will run it against 4.9 kernel that doesn't support global data), allows to test the approach and ensure that libbpf doesn't make unnecessary assumption about necessary kernel features.

2021-11-25libbpf: Load global data maps lazily on legacy kernelsAndrii Nakryiko
Load global data maps lazily, if kernel is too old to support global data. Make sure that programs are still correct by detecting if any of the to-be-loaded programs have relocation against any of such maps. This allows to solve the issue ([0]) with bpf_printk() and Clang generating unnecessary and unreferenced .rodata.strX.Y sections, but it also goes further along the CO-RE lines, allowing to have a BPF object in which some code can work on very old kernels and relies only on BPF maps explicitly, while other BPF programs might enjoy global variable support. If such programs are correctly set to not load at runtime on old kernels, bpf_object will load and function correctly now.

2021-11-19libbpf: Accommodate DWARF/compiler bug with duplicated structsAndrii Nakryiko
According to [0], compilers sometimes might produce duplicate DWARF definitions for exactly the same struct/union within the same compilation unit (CU). We've had similar issues with identical arrays and handled them with a similar workaround in 6b6e6b1d09aa ("libbpf: Accomodate DWARF/compiler bug with duplicated identical arrays"). Do the same for struct/union by ensuring that two structs/unions are exactly the same, down to the integer values of field referenced type IDs. Solving this more generically (allowing referenced types to be equivalent, but using different type IDs, all within a single CU) requires a huge complexity increase to handle many-to-many mappings between canonidal and candidate type graphs. Before we invest in that, let's see if this approach handles all the instances of this issue in practice. Thankfully it's pretty rare, it seems.

2021-11-19libbpf: Add runtime APIs to query libbpf versionAndrii Nakryiko
Libbpf provided LIBBPF_MAJOR_VERSION and LIBBPF_MINOR_VERSION macros to check libbpf version at compilation time. This doesn't cover all the needs, though, because version of libbpf that application is compiled against doesn't necessarily match the version of libbpf at runtime, especially if libbpf is used as a shared library. Add libbpf_major_version() and libbpf_minor_version() returning major and minor versions, respectively, as integers. Also add a convenience libbpf_version_string() for various tooling using libbpf to print out libbpf version in a human-readable form. Currently it will return "v0.6", but in the future it can contains some extra information, so the format itself is not part of a stable API and shouldn't be relied upon.

2021-11-18selfetests/bpf: Adapt vmtest.sh to s390 libbpf CI changesIlya Leoshkevich
[1] added s390 support to libbpf CI and added an ${ARCH} prefix to a number of paths and identifiers in libbpf GitHub repo, which vmtest.sh relies upon. Update these and make use of the new s390 support.

2021-11-18perf evsel: Fix memory leaks relating to unitIan Rogers
unit may have a strdup pointer or be to a literal, consequently memory assocciated with it isn't freed. Change it so the unit is always strdup and so the memory can be safely freed. Fix related issue in perf_event__process_event_update() for name and own_cpus. Leaks were spotted by leak sanitizer.

2021-11-18perf report: Fix memory leaks around perf_tip()Ian Rogers
perf_tip() may allocate memory or use a literal, this means memory wasn't freed if allocated. Change the API so that literals aren't used. At the same time add missing frees for system_path. These issues were spotted using leak sanitizer.
