540745ddbc70eabdc7dbd3fcc00fe4fb17cd59ba - x86/sgx: Introduce virtual EPC for use by KVM guests

Fri, 19 Mar 2021 08:22:21 +0100

x86/sgx: Introduce virtual EPC for use by KVM guestsAdd a misc device /dev/sgx_vepc to allow userspace to allocate "raw"Enclave Page Cache (EPC) without an associated enclave. The intendedand only known use case for raw EPC allocation is to expose EPC to aKVM guest, hence the 'vepc' moniker, virt.{c,h} files and X86_SGX_KVMKconfig.The SGX driver uses the misc device /dev/sgx_enclave to supportuserspace in creating an enclave. Each file descriptor returned fromopening /dev/sgx_enclave represents an enclave. Unlike the SGX driver,KVM doesn't control how the guest uses the EPC, therefore EPC allocatedto a KVM guest is not associated with an enclave, and /dev/sgx_enclaveis not suitable for allocating EPC for a KVM guest.Having separate device nodes for the SGX driver and KVM virtual EPC alsoallows separate permission control for running host SGX enclaves and KVMSGX guests.To use /dev/sgx_vepc to allocate a virtual EPC instance with particularsize, the hypervisor opens /dev/sgx_vepc, and uses mmap() with theintended size to get an address range of virtual EPC. Then it may usethe address range to create one KVM memory slot as virtual EPC fora guest.Implement the "raw" EPC allocation in the x86 core-SGX subsystem via/dev/sgx_vepc rather than in KVM. Doing so has two major advantages: - Does not require changes to KVM's uAPI, e.g. EPC gets handled as just another memory backend for guests. - EPC management is wholly contained in the SGX subsystem, e.g. SGX does not have to export any symbols, changes to reclaim flows don't need to be routed through KVM, SGX's dirty laundry doesn't have to get aired out for the world to see, and so on and so forth.The virtual EPC pages allocated to guests are currently not reclaimable.Reclaiming an EPC page used by enclave requires a special reclaimmechanism separate from normal page reclaim, and that mechanism is notsupported for virutal EPC pages. Due to the complications of handlingreclaim conflicts between guest and host, reclaiming virtual EPC pagesis significantly more complex than basic support for SGX virtualization.
