2021-02-15selftests: kvm: avoid uninitialized variable warningPaolo Bonzini
The variable in practice will never be uninitialized, because the loop will always go through at least one iteration. In case it would not, make vcpu_get_cpuid report an assertion failure. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-02-15selftests: kvm: add hardware_disable testIgnacio Alvarado
This test launches 512 VMs in serial and kills them after a random amount of time. The test was original written to exercise KVM user notifiers in the context of1650b4ebc99d: - KVM: Disable irq while unregistering user notifier - https://lore.kernel.org/kvm/CACXrx53vkO=HKfwWwk+fVpvxcNjPrYmtDZ10qWxFvVX_PTGp3g@mail.gmail.com/ Recently, this test piqued my interest because it proved useful to for AMD SNP in exercising the "in-use" pages, described in APM section 15.36.12, "Running SNP-Active Virtual Machines".

Don't bother mapping the Xen shinfo pages into the guest, they don't need to be accessed using the GVAs and passing a define with "GPA" in the name to addr_gva2hpa() is confusing.

2021-02-09KVM: x86: hyper-v: Make Hyper-V emulation enablement conditionalVitaly Kuznetsov
Hyper-V emulation is enabled in KVM unconditionally. This is bad at least from security standpoint as it is an extra attack surface. Ideally, there should be a per-VM capability explicitly enabled by VMM but currently it is not the case and we can't mandate one without breaking backwards compatibility. We can, however, check guest visible CPUIDs and only enable Hyper-V emulation when "Hv#1" interface was exposed in HYPERV_CPUID_INTERFACE. Note, VMMs are free to act in any sequence they like, e.g. they can try to set MSRs first and CPUIDs later so we still need to allow the host to read/write Hyper-V specific MSRs unconditionally.

2021-02-09selftests: kvm: Properly set Hyper-V CPUIDs in evmcs_testVitaly Kuznetsov
Generally, when Hyper-V emulation is enabled, VMM is supposed to set Hyper-V CPUID identifications so the guest knows that Hyper-V features are available. evmcs_test doesn't currently do that but so far Hyper-V emulation in KVM was enabled unconditionally. As we are about to change that, proper Hyper-V CPUID identification should be set in selftests as well.

2021-02-04KVM: x86/xen: Fix coexistence of Xen and Hyper-V hypercallsJoao Martins
Disambiguate Xen vs. Hyper-V calls by adding 'orl $0x80000000, %eax' at the start of the Hyper-V hypercall page when Xen hypercalls are also enabled. That bit is reserved in the Hyper-V ABI, and those hypercall numbers will never be used by Xen (because it does precisely the same trick). Switch to using kvm_vcpu_write_guest() while we're at it, instead of open-coding it. Signed-off-by: David Woodhouse <dwmw@amazon.co.uk>
2021-02-04KVM: x86/xen: intercept xen hypercalls if enabledJoao Martins
Add a new exit reason for emulator to handle Xen hypercalls. Since this means KVM owns the ABI, dispense with the facility for the VMM to provide its own copy of the hypercall pages; just fill them in directly using VMCALL/VMMCALL as we do for the Hyper-V hypercall page. This behaviour is enabled by a new INTERCEPT_HCALL flag in the KVM_XEN_HVM_CONFIG ioctl structure, and advertised by the same flag being returned from the KVM_CAP_XEN_HVM check. Rename xen_hvm_config() to kvm_xen_write_hypercall_page() and move it to the nascent xen.c while we're at it, and add a test case.

2021-02-04KVM: selftests: Add memslot modification stress testBen Gardon
Add a memslot modification stress test in which a memslot is repeatedly created and removed while vCPUs access memory in another memslot. Most userspaces do not create or remove memslots on running VMs which makes it hard to test races in adding and removing memslots without a dedicated test. Adding and removing a memslot also has the effect of tearing down the entire paging structure, which leads to more page faults and pressure on the page fault handling path than a one-and-done memory population test.

2021-02-04KVM: selftests: Test IPI to halted vCPU in xAPIC while backing page movesPeter Shier
When a guest is using xAPIC KVM allocates a backing page for the required EPT entry for the APIC access address set in the VMCS. If mm decides to move that page the KVM mmu notifier will update the VMCS with the new HPA. This test induces a page move to test that APIC access continues to work correctly. It is a directed test for commit e649b3f0188f "KVM: x86: Fix APIC page invalidation race".

2021-01-07tools: selftests: add test for changing routes with PTMU exceptionsSean Tranchetti
Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change. These tests explicitly test for a recently discovered problem in the IPv6 routing framework where PMTU exceptions were not properly released when replacing a route via "ip route change ...". After creating PMTU exceptions, the route from the device A to R1 will be replaced with a new route, then device A will be deleted. If the PMTU exceptions were properly cleaned up by the kernel, this device deletion will succeed. Otherwise, the unregistration of the device will stall, and messages such as the following will be logged in dmesg: unregister_netdevice: waiting for veth_A-R1 to become free.

2021-01-04selftests: Skip BPF seftests by defaultMark Brown
The BPF selftests have build time dependencies on cutting edge versions of tools in the BPF ecosystem including LLVM which are more involved to satisfy than more typical requirements like installing a package from your distribution. This causes issues for users looking at kselftest in as a whole who find that a default build of kselftest fails and that resolving this is time consuming and adds administrative overhead. The fast pace of BPF development and the need for a full BPF stack to do substantial development or validation work on the code mean that people working directly on it don't see a reasonable way to keep supporting older environments without causing problems with the usability of the BPF tests in BPF development so these requirements are unlikely to be relaxed in the immediate future. There is already support for skipping targets so in order to reduce the barrier to entry for people interested in kselftest as a whole let's use that to skip the BPF tests by default when people work with the top level kselftest build system. Users can still build the BPF selftests as part of the wider kselftest build by specifying SKIP_TARGETS, including setting an empty SKIP_TARGETS to build everything. They can also continue to build the BPF selftests individually in cases where they are specifically focused on BPF. This isn't ideal since it means people will need to take special steps to build the BPF tests but the dependencies mean that realistically this is already the case to some extent and it makes it easier for people to pick up and work with the other selftests which is hopefully a net win.
