2020-02-20Code Clean:Move getUserRegisters into dieArchSetup() and other small changes.Bin Lu
Consistent with QEMU, getUserRegisters() should be an arch-specific function. So, it should be called in dieArchSetup(). With this patch and the pagetable/pcid patch, the kvm modules on Arm64 can be built successfully. Signed-off-by: Bin Lu <bin.lu@arm.com>

2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2019-10-30support using KVM_MEM_READONLY for arm64 regionslubinszARM
On Arm platform, "setMemoryRegion" has extra permission checks. In virt/kvm/arm/mmu.c: kvm_arch_prepare_memory_region() .... if (writable && !(vma->vm_flags & VM_WRITE)) { ret = -EPERM; break; } .... So, for Arm platform, the "flags" for kvm_memory_region is required. And on x86 platform, the "flags" can be always set as '0'.

2019-09-03Impose order on test scripts.Adin Scannell
The simple test script has gotten out of control. Shard this script into different pieces and attempt to impose order on overall test structure. This change helps lay some of the foundations for future improvements. * The runsc/test directories are moved into just test/. * The runsc/test/testutil package is split into logical pieces. * The scripts/ directory contains new top-level targets. * Each test is now responsible for building targets it requires. * The install functionality is moved into `runsc` itself for simplicity. * The existing kokoro run_tests.sh file now just calls all (can be split). After this change is merged, I will create multiple distinct workflows for Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today, which should dramatically reduce the time-to-run for the Kokoro tests, and provides a better foundation for further improvements to the infrastructure.

2019-07-02Solve BounceToKernel may hang issueYong He
BounceToKernel will make vCPU quit from guest ring3 to guest ring0, but vCPUWaiter is not cleared when we unlock the vCPU, when next time this vCPU enter guest mode ring3, vCPU may enter guest mode with vCPUWaiter bit setted, this will cause the following BounceToKernel to this vCPU hangs at waitUntilNot. Halt may workaroud this issue, because halt process will reset vCPU status into vCPUUser, and notify all waiter for vCPU state change, but if there is no exception or syscall in this period, BounceToKernel will hang at waitUntilNot.
