2 Pointer authentication in AArch64 Linux
9 This document briefly describes the provision of pointer authentication
16 The ARMv8.3 Pointer Authentication extension adds primitives that can be
20 The extension uses a Pointer Authentication Code (PAC) to determine
22 a pointer, another value (such as the stack pointer), and a secret key
25 The extension adds instructions to insert a valid PAC into a pointer,
26 and to verify/remove the PAC from a pointer. The PAC occupies a number
27 of high-order bits of the pointer, which varies dependent on the
28 configured virtual address size and whether pointer tagging is in use.
52 The number of bits that the PAC occupies in a pointer is 55 minus the
57 with HINT space pointer authentication instructions protecting
59 with or without pointer authentication support.
91 Pointer authentication is enabled in KVM guest when each virtual cpu is
95 these userspace flags are checked before enabling pointer authentication.
