The changelog for 0.2.7 in terms meaningful to technical end-users.



With the release of 0.2.7 we, the ReactOS Team, have once again gained further compatibility with Microsoft Windows. We have aligned our headers with those of the Windows SDK which gives us a greater range of driver compatibility. We have also keep ourselves compliant with the latest GCC compiler which with our new build system provides a faster and more efficient building processing. We have elected a new UI coordinator and work has begun to redo the interfaces seen by the user. Many of our advancements not be easily seen by the end user, rest assured that the inter workings are coming together with work in USB, Plug and Play, and networking that will blow you away in our next release.

Main 0.2.7 Changes

Known Bugs

ReactOS will fail to boot with a AllocConsole error when a ps/2 mouse is not attached on some hardware. Bug 688

This ReactOS release requires 64MB RAM to complete the first stage installer. Bug 703

    • Fix KeWaitForMultipleObjects if WaitAll was used.
    • Rewrote Context Switching to be faster.
    • Fixed a bug where Kernel Queues were inserted on the Ready Thread list.
  • Input/Output (Io)
    • Implemented IoIsfileOriginRemote, IoGetLowerDeviceObject, IoGetDiskDeviceObject, IoGetRequestorSessionId, IoGetRequestorProcessId, IoRegisterBootDriverRetinialization, IoAttachDevicetoDeviceStackSafe, IoEnumerateDeviceObjectList, IoGetDeviceAttachmentBaseRef, IoDetachDevice, IoRaiseHardError
    • Fixed Controller Objects implementation.
    • Fixed Attaching to devices (IoAttachDevice) the driver will be notified with IO_ATTACH_DEVICE_API.

    • Optimized IoGetRelatedDeviceObject
    • Removed IoOpenDeviceInstanceKey and IoQueryDeviceEnumInfo.
    • Cleaned up IopAllocateVpb
    • Optimized IoCreateDevice, add support for more flags and remove hard-coded sector size and incorrect sizes being set.
    • Fixed IRP Code not to zero out the IRP, free MDLs in failure cases, set the right IRP flags and set the I/O Object Type.
    • Reimplemtented 2nd-stage completion for IRPs to free ALL MDLs, free memory depending on the flags used, don't call I/O Completion if an APC is registered, don't set event/call APCs in some failure cases, don't use certain fields after the pointer can become invalid.
    • Use the right stack count in I/O Operations.
    • Fixed IopDeleteFile to fix a memory leak and dereference the completion port.
    • Fixed IopCloseFile, NtQueryInformationFile, NtFlushBuffersFile, NtQueryDirectoryFile, NtReadFile, NtWriteFile, NtSetInformationFile, IopSecurityFile, IopQueryFileName, NtDeviceIoControlFile, NtLockFile, NtUnlockFile which contained several bugs related to IRPs and completion, which were making assumptions or not supporting all the possibilities, as well as signlaing the wrong event or making the wrong kind of call, or using the wrong device object.
    • Implemented Lookaside lists for IRP packets to increase the allocation/deallocation speed by over 400%.
    • Optimized Completion Packets by piggybacking them on IRP packets if possible, and added the right memory flags to free them properly.
    • Share NtDeviceIoControlFile and NtFsIoControlFile
  • Process Manager (Ps)
    • Created Memory Manager (Mm) functions when toucing process/memory
    • Created Kernel (Ke) functins when touching kernel structures and semantics.

    • Implemented NtOpenProcess, PsRemoveLoadImageNotifyRoutine, PsGetCurrentProcessSessionId, PsSetLegoNotifyRoutine, PsRemoveCreateThreadNotifyroutine, PsGetVersion
    • Rewrote Process/Thread creation and exit functions.
  • Memory Manager (Mm)
    • PEB and TEB are now properly allocated in memory, allowing 4KB granularity instead of 64KB, removed all the hacks which allowed this earlier.
    • Implement MmCreateKernelStack and MmDeleteKernelStack
    • Took out many system structures from NonPaged Pool to Paged Pool to reduce physical memory consumption.
    • Removed pool debugging functions in retail builds to increase the speed.
    • Don't allorw NtQueryVirtualMemory for kernel-mode addresses.
    • Fixed bug in memory mapping which caused large applications to BSOD the system.
    • Made the PE Loader more lenient so it can load some other valid executables.
  • Executive (Ex)
    • Fixed the lookaside functions, their macros and the way the functions were being exported.
  • Debugging Services (Dbgk/Kd)
    • Implemented some Dbgk code for user-mode bugging.
    • Implemented modular debugging services for Bochs, GDB, etc.
  • Object Manager (Ob)
    • Implemented Fast Referencing stubs.
    • Rewrote ObjectType creation to match the structures, flags and semantics present in NT's Object Manager, from the caller's point of view.
    • Implemented Object Create Information structure and semantics when capturing data from user-mode, securing and removing a lot of kernel exloits.
    • Fixed ObCreateObject and ObInsertObject to work like on Windows. ObCreateObject only allocates the Object, while ObInsertObject does everything else.
  • File System Runtime (FsRtl)
    • FsRtlMdlRead, FsRtlMdlReadComplete, FsMdlReadCompleteDev, FsRtlMdlWRiteComplete, FsRtlMdlWriteCompleteDev, FsRtlPrepareMdlWrite, CcMdlReadCompleted, CcMdlWriteComplete, CcMdlReadCompleteDev, FsRtlAllocateResource, FsRtlIsPagingFile, FsRtlBalanceReads
  • Security Subsystem (Se)
    • Implemented SeCreateAccessState, SeDeleteAccessState, SeSetAccessStateGenericMapping based on a patch fy Javier M. Mellid.


  • Implemented RtlHashUnicodeString
  • Moved ntdll's atom table implementation to rtl, rewrote it to use proper structures and share the generic implementation between ntoskrnl and ntdll
