- Finally load driver images like human beings, as actual image section objects instead of random memory that we allocate and manually "load" using unsafe and crappy PE memory copies. We now use KJK's integer-safe and properly documented/implemented loader for image sections that is already used for processes and other user-mode images.
- Implement MiLoadImageSection for the task above and remove all the deprecated code that did the previous hackloading.
svn path=/trunk/; revision=25891
- Remove /ldr ntoskrnl directory, since this module is finally gone.
- Make PsInit code search for ntdll lookups using LookupEntryPoint internal function, instead of LdrGetProcedureAddress. Same code but done with recursion instead, and internal to this module (remove ANSI_STRINGs since we don't need them anymore).
svn path=/trunk/; revision=25886
- Rename LdrUnloadModule to MmUnloadSystemImage and:
- Use MmSystemLoadLock.
- Take into consideration the import list.
- Honour load count.
- Unload symbols if really unloading the image.
- Dereference and clear imports.
- Do proper LdrEntry cleanup.
- Stub MiDereferenceImports and MmCallDllInitialize.
- Implement MiLocateExportName and MiClearImports.
- We don't yet fully support reference counting imports...this is still TBD.
svn path=/trunk/; revision=25885
- Implement MiProcessLoaderEntry for adding/removing entries on the PsLoadedModuleList.
- Move MmLoadSystemImage from loader.c to sysldr.c
- Update MmLoadSystemImage:
- Use MmSystemLoadLock.
- Support returning the entry for an already-loaded image, instead of loading it twice.
- Use Section APIs to map the image... we're still doing a dirty ZwReadFile hack, but at least now we can depend on the PE code to validate the image (so removed the hardcoded validation).
- Add more generic cleanup got so we can just jump to it.
- Add more stub code and detection code for upcoming features.
svn path=/trunk/; revision=25883
- Create and initialize Mm Loader lock.
- Re-arrange some code in MmLoadSystemImage, no code changes yet.
- Add new LDRP_ flags for LDR_DATA_TABLE_ENTRY to the NDK.
svn path=/trunk/; revision=25881
- Implement LdrPEFixupForward in FreeLDR and update LdrPEGetExportByName to use it, so that FreeLDR can now parse import tables with forwarders.
- Add call to MmInitSystem for Phase 0 in ExpInitializeExecutive.
- Completely redesign the way boot drivers are handled. They're now re-mapped during Phase 0 MmInit (part of the re-mapping is a hack until FreeLDR 2.5 is ready) and the IoMgr only does I/O stuff, not PE loading anymore (this is only half-true, we still process imports until FreeLDR 2.5 is done).
- Also re-design the way the module list head is initialized and used. LdrInit1 is now gone, Phase 0 MmInit now handles initializing it and copying boot loader data to it.
- Some code is still missing and functions still need to be improved.
- When FreeLDR 2.5 is ready some of the hacks will go away, they're #ifed for now to make it easy to switch.
svn path=/trunk/; revision=25874
- Start implementing some routines of the Mm SysLdr. Implemented MiSnapThunk and most of MiResolveImageReferences. The SysLdr has a lot of restrictions that the typical Ldr in user-mode doesn't, as well as manages imports and reference counts them, so the code can't be shared with ntdll's Ldr (this is also why real NT doesn't have an Ldr component, and this is in Mm).
- Fix some PE Header types that were wrong in our PSDK.
svn path=/trunk/; revision=25872
rewrote NtGdiDdQueryDirectDrawObject so it only copy the cache data only. This will speed up allot. we only need call on NtGdiDdCreateDirectDrawObject yo setup the whole cache and enable the drv with the helper functions. the NtGdiDdQueryDirectDrawObject will be faster like this. using RtlCopyMemory insted for RtlMemMove and allot other change in it. adding _SEH to NtGdiDdQueryDirectDrawObject so user can not crash it any longer.
svn path=/trunk/; revision=25870
- Start work on supporting NT-compatible System Loader that properly fills out LDR_DATA_TABLE_ENTRY and handles imports correctly. Modified LdpPEProcessModule to properly build the data table entry and create the base name and directory name.
- Add stub for MiResolveImageRefernces.
svn path=/trunk/; revision=25868
- Properly implement SystemExtendServiceTableInformation, except that the SE_LOAD_DRIVER_PRIVILEGE check is currently disabled since our smss doesn't acquire it (and we should therefore ban it from loading win32k.sys...).
- Delete LdrpLoadImage, LdrpUnlaodImage, LdrpLoadAndCallImage.
svn path=/trunk/; revision=25862
- Temporarily remove routines to set per-page protection (this doesn't really break anything, just makes the OS less secure).
svn path=/trunk/; revision=25861
- Remove some of the sixtuplicated routines to load a PE file. We're now down to a single function which takes an ImageType parameter for DLL/EXE/SYS, but even this is still temporary as the parameter will soon go away.
- We now load drivers in the same nice way that we load the kernel and DLLs, but we don't yet process their imports and relocate them in FreeLDR, because FreeLDR doesn't handle forwarders yet.
- We don't need a large hack in KiRosPrepareForSystemStartup anymore since the driver base addresses are now proper.
- Don't free boot-drivers anymore, since we'll load them in place soon.
- Don't load bootvid twice.
- Remove PAE stuff in FreeLDR since we don't support PAE anyway in the kernel and when we do, might as well implement it cleanly instead of relying on the broken FreeLDR stuff.
svn path=/trunk/; revision=25860
- Fix bug in KdpLoadSymbolsStateChange, we were never actually copying the pathname.
- Output of lm:
kd> lm
start end module name
80000000 80283000 nt (export symbols) ntoskrnl.exe
80283000 8029d000 hal (export symbols) halup.dll
svn path=/branches/alex-kd-branch/; revision=25858
- Implement KdpReportExceptionStateChange and fully support KdpReport.
- We now properly break inside HAL (with /BREAK) and WinDBG shows a nice stack trace, and disassembly, and I can step through the HAL initialization code!
svn path=/branches/alex-kd-branch/; revision=25857
- Implement DbgKdContinueApi and DbgKdContinueApi2 cases.
- Remove several while (TRUE);s which started being hit since our code is working fine.
- WinDBG gets notifications for all the drivers/symbols being loaded and ROS now boots to bootvid logo, but we don't yet break-in.
svn path=/branches/alex-kd-branch/; revision=25855
- Fix a bug in KdpSetContext.
- Use DR_MASK and DR7_OVERRIDE_V in KiUpdateDr7, KiRecordDr7 instead of DR_ACTIVE_MASK.
- We now get DbgKdContinueApi2 from WinDBG meaning that the first phase of KD communication is almost over!
svn path=/branches/alex-kd-branch/; revision=25854
- Fail physical memory reads for now.
- Use the right kernel load address.
- Generate image name when loading boot symbols. Now WinDBG sees "ntoskrnl.exe".
- Fix KiSaveProcessorControlState and KiRestoreProcessorControlSate. The latter doesn't freeze the CPU anymore so it's enabled, and the former doesn't cause WinDBG to panic anymore and display weird data.
svn path=/branches/alex-kd-branch/; revision=25852
- Implement KdpGetContext for DbgKdGetContextApi.
- WinDBG now goes to Phase 2 connection and prints out:
Windows Server 2003 Kernel Version 3790 UP Checked x86 compatible
Built by: 20070215-r25797
Kernel base = 0x80100000 PsLoadedModuleList = 0x80112230
svn path=/branches/alex-kd-branch/; revision=25851
- Enable kdinit.c call to KdpRestoreAllBreakpoints.
- Add breakpoint table and data.
- Support DbgKdRestoreBreakpointApi. Now we get DbgKdClearAllInternalBreakpointsApi.
svn path=/branches/alex-kd-branch/; revision=25850
- Fix bugs in KdpGetVersion, KdpReadVirtualMemory.
- Implement KdpReadControlSpace.
- Fix setting kernel range address instead of kernel image load address.
- WinDBG is slowly trying to talk with us. Now it wants to restore breakpoints since it thinks this is the same machine I was debugging last night.
svn path=/branches/alex-kd-branch/; revision=25849
- Made init.c use version data from ntverp.h instead of hard-coding.
- Defined NT 5.2.3790.1830 as the version we report.
- Fixed up .rc file to be correct and match DDK-sytnax/style.
- For now only the kernel uses this new versionning scheme, but we should change the build system later to use this for every component.
svn path=/branches/alex-kd-branch/; revision=25847
- Fix bugs in KdInitSystem; some 64-bit pointers must be sign-extneded, not zero-extended (thanks Myria!)
- Properly read kernel base instead of kernel stack.
- Fix compile issue due to incorrect KiBugCheckData definition.
- WinDBG reports: "Connected to Windows Vista 16199 x86 compatible target, ptr64 FALSE. Kernel Debugger connection established. (Initial Breakpoint requested)"
svn path=/branches/alex-kd-branch/; revision=25846
- Rename NameSpaceRoot to ObpRootDirectoryObject, IopLogListHead to IopErrorLogListHead, BugcheckCallbackListHead to KeBugcheckCallbackListHead, BugcheckReasonCallbackListHead to KeBugcheckReasonCallbackListHead, ObTypeObjectType to ObpTypeObjectType.
- Fill out KdDebuggerDataBlock with the variables that ROS currently supports. Most Mm variables we don't have yet -- it's unknown how much this will hurt WinDBG compatibility/functionality.
- Add KdPrint circular buffer and buffer location/data variables.
svn path=/branches/alex-kd-branch/; revision=25845
- Implement KdpSetCommonState (except code to clear breakpoints).
- Implement KdpSetContextState (for x86).
- Implement KdpReportLoadSymbolsStateChange.
- Implement skeleton of KdpSendWaitContinue, the main KD API Loop.
- Add KCONTINUE_STATUS.
- Redefine KdReceivePacket's return value to KDSTATUS and define possibile values.
- Add DBGKD_ANY_CONTROL_SET and X86/IA64/AMD64 control sets.
- Add DBGKD_MANIPULATE_STATE64 and all sub-structures (READ_MEMORY, WRITE_MEMORY, etc).
- Fix definition of KdpSymbol.

"The KD64 6.0 implementation is based on information from the VSJ article located at: http://www.vsj.co.uk/articles/display.asp?id=265 by Albert Alameida. Although Windows 2000 shipped with KD64 5.0, much of the implementation details have not changed. Additionally, the Windows 2000 DDK (accidentally?) shipped with a file called windbgkd.h which contains internal KD64 information and documentation. WinDBG's SDK ships with wdbgexts.h which contains more internal information on some portable structures. Other information was gathered through people such as Skywing."
