| H A D | asm.h | diff 319202 Tue May 30 12:33:17 MDT 2017 andrew MFC r316732, r316756: Enable Privileged Access Never on arm64. r316732: Use the unprivileged variant of the load and store instructions most places possible in the kernel. This forces these functions to fail if userspace is unable to access a given memory location, even if it is in the user memory range. This will simplify adding Privileged Access Never support later. r316756: In ARMv8.1 ARM has added a process state bit to disable access to userspace from the kernel. Make use of this to restrict accessing userspace to just the functions that explicitly handle crossing the user kernel boundary. |
