[edk2] [PATCH v4 00/11] Implement stack guard feature
Posted by Jian J Wang 6 years, 3 months ago
> v4:

>     to CPU_EXCEPTION_INIT_DATA
>  b. Add "size" field for all "buffer" fields in CPU_EXCEPTION_INIT_DATA

>  e. Add dummy InitializeCpuExceptionHandlersEx for ARM's CpuExceptionHandlerLib
>     and NULL version of CpuExceptionHandlerLib
>  f. Call InitializeCpuExceptionHandlersEx() in DxeMain instead of 
>     InitializeCpuExceptionHandlers().


> v2:
>  a. Introduce and implement new API InitializeCpuExceptionStackSwitchHandlers().
>  b. Add stack switch related general definitions of IA32 in BaseLib.h.
>  c. Add two new PCDs to configure exception vector list and stack size.
>  d. Add code to save/restore GDTR, IDTR and TR for AP.
>  e. Refactor exception handler code for stack switch.
>  f. Add code to setup stack switch for AP besides BSP.

Stack guard feature makes use of paging mechanism to monitor if there's a
stack overflow occurred during boot. A new PCD PcdCpuStackGuard is added to
enable/disable this feature. PCD PcdCpuStackSwitchExceptionList and
PcdCpuKnownGoodStackSize are introduced to configure the required exceptions
and stack size.

If this feature is enabled, DxeIpl will setup page tables and set page where
the stack bottom is at to be NON-PRESENT. If stack overflow occurs, Page
Fault exception will be triggered.

In order to make sure exception handler works normally even when the stack
is corrupted, stack switching is implemented in exception library.

Due to the mechanism behind Stack Guard, this feature is only avaiable for
UEFI drivers (memory avaiable). That also means it doesn't support NT32 
emulated platform (paging not supported).

Jian J Wang (11):
  MdeModulePkg/metafile: Add PCD PcdCpuStackGuard
  UefiCpuPkg/UefiCpuPkg.dec: Add two new PCDs for stack switch
  MdeModulePkg/CpuExceptionHandlerLib.h: Add a new API
    InitializeCpuExceptionHandlersEx
  MdePkg/BaseLib: Add stack switch related definitions for IA32
  UefiCpuPkg/CpuExceptionHandlerLib: Add stack switch support
  MdeModulePkg/CpuExceptionHandlerLibNull: Add new API implementation
  ArmPkg/ArmExceptionLib: Add implementation of new API
  UefiCpuPkg/MpLib: Add GDTR, IDTR and TR in saved AP data
  UefiCpuPkg/CpuDxe: Initialize stack switch for MP
  MdeModulePkg/Core/Dxe: Call new API InitializeCpuExceptionHandlersEx
    instead
  MdeModulePkg/DxeIpl: Enable paging for Stack Guard

Re: [edk2] [PATCH v4 00/11] Implement stack guard feature
Posted by Yao, Jiewen 6 years, 3 months ago
Thanks. I still think we should add version field, just in case we need add more in this CPU_EXCEPTION_INIT_DATA.

With version field added, reviewed-by: Jiewen.yao@intel.com

I suggest CpuModulePkg can double check the patch.

Thank you
Yao Jiewen
