- Yeah, this adds another regression on top of the new Ob stuff, but in the end it's for the better, as it removes more race conditions and buggy code.
- This whole week I've fixed about 45 bugs and removed a dozen race conditions, sorry for the 2-3 regressions, they will be fixed ASAP.
- DELETE MAKEFILE.AUTO BEFORE BUILDING THIS BUILD.
svn path=/trunk/; revision=25411
- Implement ObpReferenceProcessObjectByHandle and simplfy ObDuplicateObject.
- Disable hard errors while closing handles, and protect against races. Also print our error message since it seems handles aren't being closed now (message displays leak count).
- Honour DUPLICATE_CLOSE_SOURCE during failure paths in ObDuplicateObject, and catch race conditions.
- Add some more sanity checks and speed up some internal referencing.
svn path=/trunk/; revision=25408
- Add calls to ObpInitializeDirectoryLookup where required.
- Fixup calls to ObpAcquireDirectoryLockExclusive, but still keep them stubbed out for now.
svn path=/trunk/; revision=25403
- NTLPC "Branch": Ports need to maintain a Type List.
- Use proper access mode in parse callbacks.
- Properly validate the access mask given to ObpCreate(Unnamed)Handle and only grant valid bits according to ValidAccessMask.
- Use InterlockedExchangeAdd for reference count bias instead of looping on a single increment.
- Only return the object if the caller did any bias to it.
- Detach from the process much later, since exclusive process support and handle table database needs to be in the same context as the owner.
- Add audit calls to ObpCreateHandle.
- Add stubbed out calls to ObpCleanupDirectoryLookup in ObpCreateHandle.
svn path=/trunk/; revision=25400
- Save parent directory during lookups and check if the caller has the right to traverse it, if we ever need to.
- Optimize the configuration of the lookup context so that it's only done when necessary, add stub calls to lock the directory.
svn path=/trunk/; revision=25396
- Add calls to ObpInitailizeDirectoryLookup.
- Add calls to ObpCleanupDirectoryLookup but disable them for now.
- Add calls to ObpAcquireDirectoryLock but disable them for now.
svn path=/trunk/; revision=25395
- Registry code which was calling ObInsertObject for no reason at all. Now an ugly hack has been added to Cm code to perform the only operation the insert did -> to free the create info.
- SeSubProcessToken was broken and calling it incorrectly, fixed.
- \Device\PhysicalMemory was being inserted incorrectly, fixed.
- Boot-time driver objects were being inserted for no reason, call removed.
- Support the only case of ObInsertObject where it is OK to call it without an output handle. This codepath will only charge quota instead of creating the full-blown handle.
svn path=/trunk/; revision=25394
- Fixup the way we allocate object names: use paged pool instead of non-paged pool, detect insufficient memory case, detect failure to insert entry into the object directory, use name length, not maximum length when copying, use RtlCopy, not RtlMove.
- Support forcing of case-insensitivity and OBJ_FORCE_ACCESS_CHECK.
- Call ObCheckCreateObjectAccess and fail if access isn't granted.
- Call ObpCheckTraverseAccess if traversing a directory fomr user-mode and fail lookup if access wasn't granted.
- Fixup return of proper error code if we reparsed.
- Add FIXME note for SeCreateGlobalPrivilege check which is missing.
- Add callout IRQL checks around parse callouts.
- Rename some variables for clearer meaning.
- Add an extra reference when calling the parse routine in the reparse case.
svn path=/trunk/; revision=25393
- Add internal macros for incrementing/decrementing query references, and use them where appropriate. Do not yet support the path for an object which is currently being defer deleted.
- Add internal macros for cleaning up a directory lookup (not yet used and needs renaming/cleanup), initializing a directory lookup (not yet used).
- Don't call security callback in ObpDeleteNameCheck. Make sure permanent flag is still cleared after acquiring type lock. Add special call for symboilc links. Add commented out calls to lock the object directory.
svn path=/trunk/; revision=25392
-use the new extended_obj_names to prevent C::B from linking the wrong libs
-change project file version to 1.6
-compile spec, S, asm and idl files
-delete the temp rc files after building
svn path=/trunk/; revision=25390
- Implement ObpAllocateObjectNameBuffer instead of inlined code in ObpCaptureObjectAttributes. Enable usage of the Name Buffer Lookaside List since the bug in ObpFreeObjectNameBuffer has now been fixed. This should result in significant speedup and less fragmentation of pool memory.
- Allocate object names in the paged pool instead of non-paged pool, if we can't use the lookaside list.
svn path=/trunk/; revision=25389
- Fix up prototype of the function (it returns TRUE/FALSE, not NTSTATUS) and fix callers to use it properly.
- Also add ExEnumHandleTable to NDK.
svn path=/trunk/; revision=25384
- Implement support for the Handle Count Database.
- Don't do anything in IopCloseFile if this isn't the last handle for the process.
- Fix definition of OBJECT_HANDLE_COUNT_DATABASE.
svn path=/trunk/; revision=25382
- Add /fsrtl directory with new file structure and remove all the code except for some smaller "known-working" functions.
- Reason for this is that FsRtl now has a new owner (Dominique Coté) and he will be implementing and testing proper versions of the routines.
svn path=/trunk/; revision=25379
- Fix ObReferenceObjectByName to call ObpCheckObjectReference before allowing the caller to obtain the reference.
- Rename ObFindObject to ObpLookupObjectName and shuffle parameters around and add some placeholder code that resets the object pointer of the lookup context.
- Modify ObpChargeQuotaForObject to also return if this is a new object.
- Modify ObpDecrementHandleCount to detect when objects with a handle database are being used. Also protect close callout with checks. Protect ObpCloseHAndleTableEntry's callouts with checks as well.
- Update logic of ObpIncrementHandleCount and ObpIncrementUnnamedHandleCount to handle currently exclusive objects as well as new handles with OBJ_EXCLUSIVE. Also detect objects that require handle databases and protect callouts.
- Support CreatorInfo and the TypeList in ObpIncrementHandleCount. Also update the TotalNumberOfHandles in the object type properly.
- Fixup object type lock usage in these routines.
- Do proper invalid attributes check in ObOpenObjectByName, and also use a buffer from the pool instead of the stack.
- Make ObInsertObject detect invalid object insertions and change some parameter names and checks.
- Add stub code to validate the access mask in ObInsertObject. Proper initailize some lookup variables before starting lookup.
- Add detection for symbolic link inserts which require some handling code later on.
- Free the create information at the right moment isntead of too late.
- Add some missing Ob functions, flags and types to the NDK. Fix OBJECT_DIRECTORY structure to use EX_PUSH_LOCK for locks, not ERESOURCE.
svn path=/trunk/; revision=25372
- Read actual ObpLUIDDeviceMapsEnable variable do determine if shadow-searching is enabled in ObpLookupEntryDirectory.
- Currently disable all directory locking code (it was never used anyways) in ObpLookupEntryDirectory.
- Update ObpLookupEntryDirectory with placeholder code/branches for future patch implementing directory locks.
svn path=/trunk/; revision=25370
- Optimize type mutex acquisition in ObpDeleteObject. Also optimize freeing of the unicode_String containing the name. Also add callout checks/protection during the security and delete procedure callouts.
- Acquire object type mutex during modification of the OB_FLAG_PERMANENT flag in ObpSetPermanentObject.
- Initialize default QueryReferences field to 1 during object allocation.
- Support undocumented 0x10000 object attribute flag used in Windows 2003 SP1 and higher to protect objects from user-mode access (such as PhysicalMemory).
- Use InterlockedIncrements for ObjectType accounting outside the type lock.
- Clear the lookup context's object pointer for future use.
