- 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. svn path=/trunk/; revision=25238

- Replace RtlpGetExceptionAddress by the _ReturnAddress intrinsic and add it to ARM intrin.h as it was missing. - Simplify RtlpCheckForActiveDebugger: Remove the BOOLEAN parameter as we would always pass it FALSE. Always return FALSE false from kernel mode for simplicity. - Fix a critical flaw in our exception support: RtlRaiseException and RtlRaiseStatus were implemented in C on x86. This lead to unpredictable register corruption because the compiler could not know that it had to preserve non-volatile registers before calling RtlCaptureContext as the saved context is later used to restore the caller in case the exception is handled and execution is continued. This made the functions unsafe to return from as any non-volatile register could be corrupted. Implement them in assembly for x86 to safely capture the context using only EBP and ESP. The C versions of those routines are still used and shared for the other architectures we support -- needs to be determined if this is safe and correct for those architectures. - The ntdll exception Wine exposed this issue, and all tests now pass. The remaining failures on the build server are caused by missing or incomplete debug register support in KVM/QEMU. Run the test in another VM or on real hardware and all the tests will pass. - Implement Debug Prompt (DbgPrompt) support for KD and KDBG. The KDBG implementation reads the prompt from keyboard or serial depending on the mode so that sysreg and rosdbg can support it too. - Properly implement RtlAssert using DbgPrompt to prompt for the action to take instead of always doing a breakpoint. The new implementation is disabled until sysreg can support this. Also move RtlAssert to its own file as it has nothing to do with the error routines (nor does it belong in exception.c). - Note that DbgPrompt was already used in PspCatchCriticalBreak, and this would have resulted in a silent hang as BREAKPOINT_PROMPT wasn't handled at all by KDBG. - Implement KiRaiseAssertion (10 lines of code with the trap macros) and thus support NT_ASSERT. Add partial support for it to KDBG to print out a warning and the address of the failure, but don't do anything else. Also add NT_ASSERT to the DDK headers so that we can use it, but don't use it yet as the ARM method of performing this has not been decided nor implemented. - KiTrap3 doesn't set STATUS_SUCCESS but BREAKPOINT_BREAK. They have the same numerical value but very different meaning -- BREAKPOINT_BREAK means that the exception is a software breakpoint and not a debug service call. Fix some comments to document that this is what is checked for. - Fix inverted and broken logic in KdpReport. It would never pass second chance exceptions to the debugger, didn't respect the stop-on-exception flag properly and would always fail to handle some special exceptions in both first and second chance instead of just failing to handle it in first chance. Clean up, reformat and document what is going on. - The DebugPrint and DebugPrompt support routines only perform a 2D interrupt on x86; use more portable comments. - Add Alex to the programmer section of x86's kdsup.c -- he wrote KdpGetStateChange, KdpSetContextState and the code that was previously in KdpRead/WriteControlSpace. - Add my name to the parts of KD where I have made significant work on getting KD/WinDbg support up and running. - KD debugging is now quite functional and stable. Some bugs and stubs remain to be flushed out, but overall KD is now much better and easier to use than KDBG. svn path=/trunk/; revision=43705

- Fix support for /CRASHDEBUG and /NODEBUG; we didn't respect those settings properly and would initialize KD at boot even if they were set. - Re-enable the breakpoint in vDbgPrintExWithPrefixInternal() as this works properly now. Without this breakpoint some break-in requests got lost if the break-in occurred when handling a debug print (happened a lot at boot). - Implement Command String support for DbgCommandString() -- we now handle every debug service call. - Implement NtSetDebugFilterState() and NtQueryDebugFilterState() for KD, meaning we now support debug filters properly. - Implement KdRefreshDebuggerNotPresent(), KdChangeOption() and KdPowerTransition(). Stub KdSystemDebugControl() to return error status instead of hanging the system. - Stub the rest of the KD API to print a warning and return a failure packet instead of hanging. - Set and respect KdpContextSent when getting and setting the thread context -- WinDbg doesn't seem to rely on this, but better safe than sorry. - Support MP when getting and setting the thread context too -- if the context is operation is for another processor than the current, just get it through the KiProcessorBlock array. - Initialize the MajorVersion in the KD version block more properly -- the high byte is the major identifier (0 for NT). Add the required DBGKD_MAJOR_TYPES enumeration to wdbgexts.h. - Simplify setting and clearing the InDbgPrint flag in the TEB to minimize the impact on kernel execution; use 2 dedicated routines instead of a generic one. - KdpSymbol doesn't return anything, so don't return an ignore status from KdpReportLoadSymbolsStateChange. - Expose the KdpDefaultRetries and Kd_WIN2000_Mask variables to the registry and add them to KDBG too (unused there). - No reason to implement KdpSysGetVersion per architecture; move it back to the generic code. - Add some ARM offsets to the debugger data block that (N/A on other architectures). - Fix the default size of the DbgPrint log buffer for free builds to save some space. It should be 4 KB for a free build and 32 KB for a checked build. - Move KeDisableInterrupts to cpu.c as it fits here more than in the IRQ support code in irqobj.c. - Use KeDisableInterrupts in KeFreezeExecution instead of checking the x86 EFLAG directly. svn path=/trunk/; revision=43912

- DBGKD_WAIT_STATE_CHANGE64 is used in KD protocol 5, not number 6 that we use. Protocol 6 uses the DBGKD_ANY_WAIT_STATE_CHANGE structure which is sized according to the largest control-report structure (AMD64_DBGKD_CONTROL_REPORT currently), and is larger than DBGKD_WAIT_STATE_CHANGE64 on x86. This worked because our DBGKD_WAIT_STATE_CHANGE32/64 structures contained incorrect DBGKD_CONTROL_REPORT (used) and CONTEXT (unused) members that sized up the wait-state structure to pass WinDbg's length verification! It actually becomes larger than DBGKD_ANY_WAIT_STATE_CHANGE, but WinDbg only seems bail out only if the structure is too small. Remove the incorrect members from the protocol 5 structures and change to DBGKD_ANY_WAIT_STATE_CHANGE everywhere. - Correct the value of SIZE_OF_FX_REGISTERS -- it was 4 times too low which resulted in KeContextToTrapFrame not properly clearing out the XMM register area. Correct the define and move it out from ke.h to x86's ketypes.h and use it in the FXSAVE format structure. Also remove the IOPM definitions from ke.h as they have been in the NDK for a while. - KD uses STRINGs, not ANSI_STRINGs -- they are the same thing, but let's be consistent. - ExceptionRecord32To64 should be available for both 32 and 64 bit builds (and it shouldn't be a forceinline). Get rid of CopyExceptionRecord and determine if we need to convert or can just copy it directly instead. - Use _WIN64 instead of _M_AMD64 when determining if we need to set the DBGKD_VERS_FLAG_PTR64 flag. - Don't check Nt/DbgQueryDebugFilterState for zero or nonzero -- it actually returns TRUE, FALSE or STATUS_INVALID_PARAMETER_1! Check for != TRUE in preparation for proper implementation of NtSet/QueryDebugFilterState. - Fix Format parameter of DbgPrintReturnControlC -- it is const like the other DbgPrint* routines. - Be consistent with the types used in debug.c and don't set local variables to zero if we are going to return to caller -- this doesn't seem to be required anymore. - Fix DebugService and DebugService2: DebugService should take a ULONG followed by 4 pointers and DebugService2 doesn't return anything. - Use ZwCurrentProcess() instead of -1 or 0xFFFFFFFF (which is incorrect for 64-bit) for the ProcessId parameter of DbgLoad/UnloadImageSymbols to clarify what is being passed. Don't use ZwCurrentProcess() in KeBugCheckWithTf for the pointer parameter of DbgUnLoadImageSymbols either. Use MAXULONG_PTR casted to PVOID instead. - Use better named and sized variables in KdpTrap for setting the "return register" in the caller's CONTEXT. - Correct and clarify the comment documenting under what conditions we pass user mode exceptions to the kernel debugger. svn path=/trunk/; revision=43741
