commit 4dc1815991420b809ce18dddfdf9c0af48944204
Author: Jan Beulich <jbeulich@suse.com>

x86/PV: harden guest memory accesses against speculative abuse
Inspired by
https://lore.kernel.org/lkml/f12e7d3cecf41b2c29734ea45a393be21d4a8058.1597848273.git.jpoimboe@redhat.com/
and prior work in that area of x86 Linux, suppress speculation with
guest specified pointer values by suitably masking the addresses to
non-canonical space in case they fall into Xen's virtual address range.
Introduce a new Kconfig control.
Note that it is necessary in such code to avoid using "m" kind operands:
If we didn't, there would be no guarantee that the register passed to
guest_access_mask_ptr is also the (base) one used for the memory access.
As a minor unrelated change in get_unsafe_asm() the unnecessary "itype"
parameter gets dropped and the XOR on the fixup path gets changed to be
a 32-bit one in all cases: This way we avoid pointless REX.W or operand
size overrides, or writes to partial registers.

x86/PV: harden guest memory accesses against speculative abuse
Inspired by
https://lore.kernel.org/lkml/f12e7d3cecf41b2c29734ea45a393be21d4a8058.1597848273.git.jpoimboe@redhat.com/
and prior work in that area of x86 Linux, suppress speculation with
guest specified pointer values by suitably masking the addresses to
non-canonical space in case they fall into Xen's virtual address range.
Introduce a new Kconfig control.
Note that it is necessary in such code to avoid using "m" kind operands:
If we didn't, there would be no guarantee that the register passed to
guest_access_mask_ptr is also the (base) one used for the memory access.
As a minor unrelated change in get_unsafe_asm() the unnecessary "itype"
parameter gets dropped and the XOR on the fixup path gets changed to be
a 32-bit one in all cases: This way we avoid pointless REX.W or operand
size overrides, or writes to partial registers.

x86/pv: Drop int80_bounce from struct pv_vcpu
The int80_bounce field of struct pv_vcpu is a bit of an odd special case,
because it is a simple derivation of trap_ctxt[0x80], which is also stored.
It is also the only use of {compat_,}create_bounce_frame() which isn't
referencing the plain trap_bounce field of struct pv_vcpu. (And altering this
property the purpose of this patch.)
Remove the int80_bounce field entirely, along with init_int80_direct_trap(),
which in turn requires that the int80_direct_trap() path gain logic previously
contained in init_int80_direct_trap().
This does admittedly make the int80 fastpath slightly longer, but these few
instructions are in the noise compared to the architectural context switch
overhead, and it now matches the syscall/sysenter paths (which have far less
architectural overhead already).
No behavioural change from the guests point of view.
