Other than verifying pidfd based polling, the tests make sure that wait semantics are preserved with the pidfd poll. Notably the 2 cases: 1. If a thread group leader exits while threads still there, then no pidfd poll notifcation should happen. 2. If a non-thread group leader does an execve, then the thread group leader is signaled to exit and is replaced with the execing thread as the new leader, however the parent is not notified in this case.

2019-06-25tc-testing: Restore original behaviour for namespaces in tdcLucas Bates
This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.

Commit 332d079735f5 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state", 2019-05-02) broke evmcs_test because the eVMCS setup must be performed even if there is no VMXON region defined, as long as the eVMCS bit is set in the assist page. While the simplest possible fix would be to add a check on kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly. Instead, this patch moves checks earlier in the function and conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that vmx_set_nested_state always goes through vmx_leave_nested and nested_enable_evmcs.

2019-06-19tests: kvm: Check for a kernel warningAaron Lewis
When running with /sys/module/kvm_intel/parameters/unrestricted_guest=N, test that a kernel warning does not occur informing us that vcpu->mmio_needed=1. This can happen when KVM_RUN is called after a triple fault. This test was made to detect a bug that was reported by Syzkaller (https://groups.google.com/forum/#!topic/syzkaller/lHfau8E3SOE) and fixed with commit bbeac2830f4de ("KVM: X86: Fix residual mmio emulation request to userspace").

2019-06-19KVM: x86: Modify struct kvm_nested_state to have explicit fields for dataLiran Alon
Improve the KVM_{GET,SET}_NESTED_STATE structs by detailing the format of VMX nested state data in a struct. In order to avoid changing the ioctl values of KVM_{GET,SET}_NESTED_STATE, there is a need to preserve sizeof(struct kvm_nested_state). This is done by defining the data struct as "data.vmx[0]". It was the most elegant way I found to preserve struct size while still keeping struct readable and easy to maintain. It does have a misfortunate side-effect that now it has to be accessed as "data.vmx[0]" rather than just "data.vmx". Because we are already modifying these structs, I also modified the following: * Define the "format" field values as macros. * Rename vmcs_pa to vmcs12_pa for better readability.
