- Fix critical bugs in exception handling: Unwinding was completely broken, using the wrong SEH protector to detect collided unwinding. The correct protector itself also had a broken check.
- Fix architectural bug in the entire TrapFrame<->Context conversion system and Ring Privilege Transitions (Inter-ring and intra-ring) which was lacking proper sanitation and validation of segments, flags and debug registers. Among other things, IOPL is now respected, CS is not KGDT_R0_CODE | RPL_MASK anymore, and the GPF code is now properly being called. This completely fixes exception handling being totally broken and crashing firefox installer, mirc, and other applications.
- Rewrite the page fault handler base code in assembly instead of relying on a broken C routine. Detect VDM, V8086, detecting expected/normal fault in ExpInterlockedPopEntrySList and faults in the system handler code. Rewrite MmAccessFault to be the main function that calls out to other sub-fault functions, and use the same prototype as NT.
- Fix the KGDT boot table to have proper granularity and big flags, and extend it to 256 entries.
- Create proper thread context in RtlInitializeContext and cleanup Rtl Thread routines.
- Remove all int3 and breakpoints from trap handlers, and replace them with a much better "UNHANDLED_PATH" macro which freezes the system, beeps, and displays a message with the line of code that's unhandled. This is to clearly tell the user that something is unhandled, instead of nesting infinite exceptions due to the int3.
- Fix a bug in INT_PROLOG.
- Sanitize EFLAGS and Code Segments in KeContextToTrapFrame and KeTrapFrameToContext.
- Implement KiUpdateDr7 and KiRecordDr7 as well as DR_MASK and other DR-validation macros and functions to protect against DR-vulnerabilites as well as to properly account for each active hardware breakpoint in a per-thread fashion by using the dispatcher header.
- Allow CR0_EM when running in a VDM.
- Fix FPU/NPX Register handling in KeContextToTrapFrame and KeTrapFrameToContext, and also speed it up by manual copying instead of a memory move.
- Properly give IOPL 3 to user-mode threads if they requested it.
- Detect GPF during GPF.
- Detect pagefault with a trap-frame spread over two or more pages and nested.
- Properly sanitize and set correct trap frame in KiInitailizeUserApc.
- Return STATUS_ACCESS_VIOLATION during page faults instead of STATUS_UNSUCESSFUL.
- Fix assert in VdmSwapContext, as well as Code Selector check which was broken.
- Fix delayed object deletion (ObDeferDeleteObject) and the Ob Repear Routine and list.
- Update Kernel Fun.
- BUGBUG: Temporaily hack VMWare to detection to always detect VMWare.
