2021-04-06x86/sgx: Add SGX2 ENCLS leaf definitions (EAUG, EMODPR and EMODT)Sean Christopherson
Define the ENCLS leafs that are available with SGX2, also referred to as Enclave Dynamic Memory Management (EDMM). The leafs will be used by KVM to conditionally expose SGX2 capabilities to guests.

2021-04-06x86/sgx: Expose SGX architectural definitions to the kernelSean Christopherson
Expose SGX architectural structures, as KVM will use many of the architectural constants and structs to virtualize SGX. Name the new header file as asm/sgx.h, rather than asm/sgx_arch.h, to have single header to provide SGX facilities to share with other kernel componments.

2021-04-06x86/sgx: Initialize virtual EPC driver even when SGX driver is disabledKai Huang
Modify sgx_init() to always try to initialize the virtual EPC driver, even if the SGX driver is disabled. The SGX driver might be disabled if SGX Launch Control is in locked mode, or not supported in the hardware at all. This allows (non-Linux) guests that support non-LC configurations to use SGX.

2021-04-06x86/cpu/intel: Allow SGX virtualization without Launch Control supportSean Christopherson
The kernel will currently disable all SGX support if the hardware does not support launch control. Make it more permissive to allow SGX virtualization on systems without Launch Control support. This will allow KVM to expose SGX to guests that have less-strict requirements on the availability of flexible launch control. Improve error message to distinguish between three cases. There are two cases where SGX support is completely disabled: 1) SGX has been disabled completely by the BIOS 2) SGX LC is locked by the BIOS. Bare-metal support is disabled because of LC unavailability. SGX virtualization is unavailable (because of Kconfig). One where it is partially available: 3) SGX LC is locked by the BIOS. Bare-metal support is disabled because of LC unavailability. SGX virtualization is supported.

2021-04-06x86/sgx: Introduce virtual EPC for use by KVM guestsSean Christopherson
Add a misc device /dev/sgx_vepc to allow userspace to allocate "raw" Enclave Page Cache (EPC) without an associated enclave. The intended and only known use case for raw EPC allocation is to expose EPC to a KVM guest, hence the 'vepc' moniker, virt.{c,h} files and X86_SGX_KVM Kconfig. The SGX driver uses the misc device /dev/sgx_enclave to support userspace in creating an enclave. Each file descriptor returned from opening /dev/sgx_enclave represents an enclave. Unlike the SGX driver, KVM doesn't control how the guest uses the EPC, therefore EPC allocated to a KVM guest is not associated with an enclave, and /dev/sgx_enclave is not suitable for allocating EPC for a KVM guest. Having separate device nodes for the SGX driver and KVM virtual EPC also allows separate permission control for running host SGX enclaves and KVM SGX guests. To use /dev/sgx_vepc to allocate a virtual EPC instance with particular size, the hypervisor opens /dev/sgx_vepc, and uses mmap() with the intended size to get an address range of virtual EPC. Then it may use the address range to create one KVM memory slot as virtual EPC for a 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 reclaim mechanism separate from normal page reclaim, and that mechanism is not supported for virutal EPC pages. Due to the complications of handling reclaim conflicts between guest and host, reclaiming virtual EPC pages is significantly more complex than basic support for SGX virtualization.

2021-04-05s390/pci: expose UID uniqueness guaranteeNiklas Schnelle
On s390 each PCI device has a user-defined ID (UID) exposed under /sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI device's primary index and to match the device within Linux to the device configured in the hypervisor. To serve as a primary identifier the UID must be unique within the Linux instance, this is guaranteed by the platform if and only if the UID Uniqueness Checking flag is set within the CLP List PCI Functions response. While the UID has been exposed to userspace since commit ac4995b9d570 ("s390/pci: add some new arch specific pci attributes") whether or not the platform guarantees its uniqueness for the lifetime of the Linux instance while defined is not visible from userspace. Remedy this by exposing this as a per device attribute at /sys/bus/pci/devices/<dev>/uid_is_unique Keeping this a per device attribute allows for maximum flexibility if we ever end up with some devices not having a UID or not enjoying the guaranteed uniqueness.

2021-04-04xtensa: ISS: add GDBIO implementation to semihosting interfaceMax Filippov
Add GDBIO implementation for the xtensa semihosting interface. It offers less functions than the simcall interface, so make some semihosting functions optional and return error when implementation is not available. Add Kconfig menu to select semihosting implementation and add simcall and GDBIO choices there. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2021-04-04xtensa: simplify coherent_kvaddr logicMax Filippov
Functions coherent_kvaddr, clear_page_alias and copy_page_alias use physical address 0 as a special value that means 'this page is in the KSEG mapping and its existing virtual address has the same color as the virtual address of its future mapping, so don't map it to the TLBTEMP_BASE area'. Simplify this logic and drop special handling of low memory pages/pages with coherent mapping and always use TLBTEMP_BASE area. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2021-04-04xtensa: stop filling syscall array with sys_ni_syscallMasahiro Yamada
arch/xtensa/kernel/syscalls/syscalltbl.sh fills missing syscall numbers with sys_ni_syscall. So, the generated arch/xtensa/include/generated/asm/syscall_table.h has no hole. Hence, the line: [0 ... __NR_syscalls - 1] = (syscall_t)&sys_ni_syscall, is meaningless. The number of generated __SYSCALL() macros is the same as __NR_syscalls (this is 442 as of v5.11). Hence, the array size, [__NR_syscalls] is unneeded. The designated initializer, '[nr] =', is also unneeded. This file does not need to know __NR_syscalls. Drop the unneeded <asm/unistd.h> include directive.
