2023-06-01KVM: selftests: Add dirty logging page splitting testBen Gardon
Add a test for page splitting during dirty logging and for hugepage recovery after dirty logging. Page splitting represents non-trivial behavior, which is complicated by MANUAL_PROTECT mode, which causes pages to be split on the first clear, instead of when dirty logging is enabled. Add a test which makes assertions about page counts to help define the expected behavior of page splitting and to provide needed coverage of the behavior. This also helps ensure that a failure in eager page splitting is not covered up by splitting in the vCPU path. Tested by running the test on an Intel Haswell machine w/wo MANUAL_PROTECT.

2023-06-01KVM: selftests: touch all pages of args on each memstress iterationPaolo Bonzini
Access the same memory addresses on each iteration of the memstress guest code. This ensures that the state of KVM's page tables is the same after every iteration, including the pages that host the guest page tables for args and vcpu_args. This difference is visible when running the proposed dirty_log_page_splitting_test[*] on AMD, or on Intel with pml=0 and eptad=0. The tests fail due to different semantics of dirty bits for page-table pages on AMD (and eptad=0) and Intel. Both AMD and Intel with eptad=0 treat page-table accesses as writes, therefore more pages are dropped before the repopulation phase when dirty logging is disabled. The "missing" page had been included in the population phase because it hosts the page tables for vcpu_args, but repopulation does not need it."

Don't just check the raw PMU type, the only core PMU on homogeneous x86, check raw and all dynamically added PMUs. Extend the perf_pmu__warn_invalid_config to check all 4 config values. Rather than process the format list once per event, store the computed masks for each config value. Don't ignore the mask being zero, which is likely for config2 and config3, add config_masks_present so config values can be ignored only when no format information is present.

2023-06-01selftests/bpf: Test table ID fib lookup BPF helperLouis DeLosSantos
Add additional test cases to `fib_lookup.c` prog_test. These test cases add a new /24 network to the previously unused veth2 device, removes the directly connected route from the main routing table and moves it to table 100. The first test case then confirms a fib lookup for a remote address in this directly connected network, using the main routing table fails. The second test case ensures the same fib lookup using table 100 succeeds. An additional pair of tests which function in the same manner are added for IPv6.

2023-06-01bpf: Add table ID to bpf_fib_lookup BPF helperLouis DeLosSantos
Add ability to specify routing table ID to the `bpf_fib_lookup` BPF helper. A new field `tbid` is added to `struct bpf_fib_lookup` used as parameters to the `bpf_fib_lookup` BPF helper. When the helper is called with the `BPF_FIB_LOOKUP_DIRECT` and `BPF_FIB_LOOKUP_TBID` flags the `tbid` field in `struct bpf_fib_lookup` will be used as the table ID for the fib lookup. If the `tbid` does not exist the fib lookup will fail with `BPF_FIB_LKUP_RET_NOT_FWDED`. The `tbid` field becomes a union over the vlan related output fields in `struct bpf_fib_lookup` and will be zeroed immediately after usage. This functionality is useful in containerized environments. For instance, if a CNI wants to dictate the next-hop for traffic leaving a container it can create a container-specific routing table and perform a fib lookup against this table in a "host-net-namespace-side" TC program. This functionality also allows `ip rule` like functionality at the TC layer, allowing an eBPF program to pick a routing table based on some aspect of the sk_buff. As a concrete use case, this feature will be used in Cilium's SRv6 L3VPN datapath. When egress traffic leaves a Pod an eBPF program attached by Cilium will determine which VRF the egress traffic should target, and then perform a FIB lookup in a specific table representing this VRF's FIB.

2023-06-01perf test: Update parse-events expectations to test for multiple eventsIan Rogers

2023-06-01perf parse-events: Wildcard most "numeric" eventsIan Rogers
Numeric events are either raw events or those with ABI defined numbers matched by the lexer. PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE events should wildcard match on hybrid systems. So "cycles" should match each PMU type with an extended type, not just PERF_TYPE_HARDWARE. Change wildcard matching to add the event even if wildcard PMU scanning fails, there will be no extended type but this best matches previous behavior. Only set the extended type when the event type supports it and when perf_pmus__supports_extended_type is true. This new function returns true if >1 core PMU and avoids potential errors on older kernels. Modify evsel__compute_group_pmu_name using a helper perf_pmu__is_software to determine when grouping should occur. Try to use PMUs, and evsel__find_pmu, as being more dependable than evsel->pmu_name. Set a parse events error if a hardware term's PMU lookup fails, to provide extra diagnostics.
