Subject: [PATCH v4 for-4.9 00/24] [SUBSET] XSA-191 followup
Date: Thu, 1 Dec 2016 16:55:56 +0000 [thread overview]
Message-ID: <1480611361-15294-1-git-send-email-andrew.cooper3@citrix.com> (raw)
This is the quantity of changes required to fix some edgecases in XSA-191
which were ultimately chosen not to go out in the security fix. The main
purpose of this series is to fix emulation sufficiently to allow the final
patch to avoid opencoding all of the segmenation logic.
Because this is a very long series and there are not many changes from v3, I
am only sending out the patches which have changes, to avoid spamming the
list.
Andrew Cooper (24):
x86/shadow: Fix #PFs from emulated writes crossing a page boundary
x86/emul: Drop X86EMUL_CMPXCHG_FAILED
x86/emul: Simplfy emulation state setup
x86/emul: Rename hvm_trap to x86_event and move it into the emulation infrastructure
x86/emul: Rename HVM_DELIVER_NO_ERROR_CODE to X86_EVENT_NO_EC
x86/pv: Implement pv_inject_{event,page_fault,hw_exception}()
x86/emul: Clean up the naming of the retire union
x86/emul: Correct the behaviour of pop %ss and interrupt shadowing
x86/emul: Provide a wrapper to x86_emulate() to ASSERT() certain behaviour
x86/emul: Always use fault semantics for software events
x86/emul: Implement singlestep as a retire flag
x86/emul: Remove opencoded exception generation
x86/emul: Rework emulator event injection
x86/vmx: Use hvm_{get,set}_segment_register() rather than vmx_{get,set}_segment_register()
x86/hvm: Reposition the modification of raw segment data from the VMCB/VMCS
x86/emul: Avoid raising faults behind the emulators back
x86/pv: Avoid raising faults behind the emulators back
x86/shadow: Avoid raising faults behind the emulators back
x86/hvm: Extend the hvm_copy_*() API with a pagefault_info pointer

x86/hvm: Rename hvm_copy_*_guest_virt() to hvm_copy_*_guest_linear()
x86/hvm: Avoid __hvm_copy() raising #PF behind the emulators back
x86/emul: Prepare to allow use of system segments for memory references
x86/emul: Use system-segment relative memory accesses
