IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it. The functions which we touched are: - IoAllocateIrp - IoBuild[A]SyncronousFsdRequest - IoBuildDeviceIoControlRequest - IoInitializeIrp - IoPageRead, IoSynchronousPageWrite svn path=/trunk/; revision=14837

IopCreateFile(PVOID ObjectBody,

PWSTR RemainingPath,
Object Manager Patch. This patch continues the work done in the previous patch and makes the following changes in order to support OB 2.0 (it basically temporarily fixes a highly incorrect implementation so that caller code will be ready to work with the OB 2.0 without change): 1) The documented Object Create Information Structure and semantics implemented. All Object Attributes and passed data from user-mode is now probed and saved into this object create structure when ObCreateObject is called. 2) ObCreateObject does NOT PERFORM ANY OTHER OPERATION EXCEPT CREATING THE OBJECT ANYMORE. ObCreateObject will NOT insert the Object into the tree and other operations. These are now done correctly by ObInsertObject. Therefore, the biggest hurdle was changing pieces of code which assumed ObCreateObject would be enough. 3) ObInsertObject uses the captured create info for all operations isntead of the Object Attributes. 4) ObFindObject now uses the captured info as well. 5) The OBject name and directory are now stored in the documented Object Name Information, always allocated and freed from non paged pool. HACKS: 5) Because the registry code is horribly broken and doesn't use ObFindObjectByName, the old ObFindObject had to be temporarily duplicated into CmpFindObject. 7) Win32k used ObInsertObject in CsrInsertObject as a way to create a handle inside csrss. However, OBInsertObject now does more then this. As a temporary hack, ObpCreateHandle is exported from the kernel and called from win32k. A fix needs to be done for this, but I don't know the design of win32k+csrss well enough to find a solution. 8) SEH has been commented out in some places of the new probing code because it breaks smss and explorer. These need to be investigated (seh did not exist in the previous code, so this is not really a hack) 9) Named objects with a parent directory are NOT allowed. However because of bugs in kernel32, the new check has been temporarily disabled. (this check did not exist in the previous code, so this is not really a hack) The next patch will add a proper ObFindObject which will support a more complete Parse Procedure with context and security information. This is needed for proper registry access (requested by Eric Kohl) and for proper functionality of the Desktop/File creation, which should use the Parse routine, and not the Create Handle Routine. This will also make it possible to remove some previous hacks and pave the way for a fixed Iop/IoCreateFile svn path=/trunk/; revision=15395

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it.

Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed.

* DESCRIPTION
* Either causes a new file or directory to be created, or it
* opens an existing file, device, directory or volume, giving
* the caller a handle for the file object. This handle can be
* used by subsequent calls to manipulate data within the file
* or the file object's state of attributes.

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions.

This patch continues the work done in the previous patch and makes the following changes in order to support OB 2.0 (it basically temporarily fixes a highly incorrect implementation so that caller code will be ready to work with the OB 2.0 without change): 1) The documented Object Create Information Structure and semantics implemented. All Object Attributes and passed data from user-mode is now probed and saved into this object create structure when ObCreateObject is called. 2) ObCreateObject does NOT PERFORM ANY OTHER OPERATION EXCEPT CREATING THE OBJECT ANYMORE. ObCreateObject will NOT insert the Object into the tree and other operations. These are now done correctly by ObInsertObject. Therefore, the biggest hurdle was changing pieces of code which assumed ObCreateObject would be enough. 3) ObInsertObject uses the captured create info for all operations isntead of the Object Attributes. 4) ObFindObject now uses the captured info as well. 5) The OBject name and directory are now stored in the documented Object Name Information, always allocated and freed from non paged pool. HACKS: 5) Because the registry code is horribly broken and doesn't use ObFindObjectByName, the old ObFindObject had to be temporarily duplicated into CmpFindObject. 7) Win32k used ObInsertObject in CsrInsertObject as a way to create a handle inside csrss. However, OBInsertObject now does more then this. As a temporary hack, ObpCreateHandle is exported from the kernel and called from win32k. A fix needs to be done for this, but I don't know the design of win32k+csrss well enough to find a solution. 8) SEH has been commented out in some places of the new probing code because it breaks smss and explorer. These need to be investigated (seh did not exist in the previous code, so this is not really a hack) 9) Named objects with a parent directory are NOT allowed. However because of bugs in kernel32, the new check has been temporarily disabled. (this check did not exist in the previous code, so this is not really a hack) The next patch will add a proper ObFindObject which will support a more complete Parse Procedure with context and security information. This is needed for proper registry access (requested by Eric Kohl) and for proper functionality of the Desktop/File creation, which should use the Parse routine, and not the Create Handle Routine. This will also make it possible to remove some previous hacks and pave the way for a fixed Iop/IoCreateFile svn path=/trunk/; revision=15395

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it.

Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it. The functions which we touched are: - IoAllocateIrp - IoBuild[A]SyncronousFsdRequest - IoBuildDeviceIoControlRequest - IoInitializeIrp - IoPageRead, IoSynchronousPageWrite svn path=/trunk/; revision=14837

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it.

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file.

We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it.

We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions.

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it. The functions which we touched are: - IoAllocateIrp - IoBuild[A]SyncronousFsdRequest - IoBuildDeviceIoControlRequest - IoInitializeIrp - IoPageRead, IoSynchronousPageWrite svn path=/trunk/; revision=14837

Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions. This and the deletions have resulted in a completely bloated diff file. I will provide a cleaned up diff on request by manually downloading the old revision and copy/pasting the new code directly above it.

IO Manager Cleanup continues: - Removed many extra files that expanded the I/O Manager too much. We usually stick with the standard of one object/class per file, like io/device.c or io/controller.c, so it was very confusing to have some objects split up in 5 or 6 different files, some containing only one api. Additionally, even a third system was used, were objects were bunched up together by class. This mess was so bad that NtCreateFile, IopCreateFile, IoCreateFile, IopDeleteFile, NtDeleteFile and NtWriteFile were in 5 different files (as an example). - Cleaned up some IRP code and fixed a couple of bugs, mainly: - Write I/O Type in IRP - Write proper IRP Flags where they shoudl be used (Will help for completing requests when i clean up that code) - Do *NOT* zero out buffers or data that shouldn't be zeroed. Scsiport actually dependen on this incorrect behaviour. Code should never depend on a buffer being zeroed! - Remove a lot of duplicated code and helper/alternate functions that weren't really useful. - Free MDL and IRP on some failures where we didn't - Alphabetized some of the large io files for easier lookup of functions.
