vmx_recover_nmi_blocking is using a cached value of the guest interruptibility info, which is stored in vmx->nmi_known_unmasked. vmx_recover_nmi_blocking is run for both normal and nested guests, so the cached value must be per-VMCS. This fixes eventinj.flat in a nested non-EPT environment. With EPT it works, because the EPT violation handler doesn't have the vmx->nmi_known_unmasked optimization (it is unnecessary because, unlike vmx_recover_nmi_blocking, it can just look at the exit qualification). Thanks to Wanpeng Li for debugging the testcase and providing an initial patch. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
