Queries information details about a security descriptor.

Computes the quota size of a security descriptor.

Assigns a security descriptor for a new object.

An extended function that assigns a security descriptor for a new object.

Frees a security descriptor.

An extended function that sets new information data to a security descriptor.

Modifies some information data about a security descriptor.

Parameters

[in]	SecurityInformation	Security information details to be queried from a security descriptor.
[out]	SecurityDescriptor	The returned security descriptor with security information data.
[in,out]	Length	The returned length of a security descriptor.
[in,out]	ObjectsSecurityDescriptor	The returned object security descriptor.

Returns

Returns STATUS_SUCCESS if the operations have been completed successfully and that the specific information about the security descriptor has been queried. STATUS_BUFFER_TOO_SMALL is returned if the buffer size is too small to contain the queried info about the security descriptor.

Parameters

[in]	Object	If specified, the function will use this arbitrary object that points to an object security descriptor.
[in]	SecurityInformation	Security information details to be set.
[in]	SecurityDescriptor	A security descriptor where its info is to be changed.
[in,out]	ObjectsSecurityDescriptor	The returned pointer to security descriptor objects.
[in]	PoolType	Pool type for the new security descriptor to allocate.
[in]	GenericMapping	The generic mapping of access rights masks.

Returns

See SeSetSecurityDescriptorInfoEx.

Parameters

[in]	Object	If specified, the function will use this arbitrary object that points to an object security descriptor.
[in]	SecurityInformation	Security information details to be set.
[in]	SecurityDescriptor	A security descriptor where its info is to be changed.
[in,out]	ObjectsSecurityDescriptor	The returned pointer to security descriptor objects.
[in]	AutoInheritFlags	Flags bitmask inheritation, influencing how the security descriptor can be inherited and if it can be in the first place.
[in]	PoolType	Pool type for the new security descriptor to allocate.
[in]	GenericMapping	The generic mapping of access rights masks.

Returns

Returns STATUS_SUCCESS if the operations have been completed without problems and that new info has been set to the security descriptor. STATUS_NO_SECURITY_ON_OBJECT is returned if the object does not have a security descriptor. STATUS_INSUFFICIENT_RESOURCES is returned if memory pool allocation for the new security descriptor with new info set has failed.

Parameters

[in]

SecurityDescriptor

A security descriptor to be freed from memory.

Returns

Returns STATUS_SUCCESS.

Parameters

[in]	_ParentDescriptor	A security descriptor of the parent object that is being created.
[in]	_ExplicitDescriptor	An explicit security descriptor that is applied to a new object.
[out]	NewDescriptor	The new allocated security descriptor.
[in]	ObjectType	The type of the new object.
[in]	IsDirectoryObject	Set this to TRUE if the newly created object is a directory object, otherwise set this to FALSE.
[in]	AutoInheritFlags	Automatic inheritance flags that influence how access control entries within ACLs from security descriptors are inherited.
[in]	SubjectContext	Security subject context of the new object.
[in]	GenericMapping	Generic mapping of access mask rights.
[in]	PoolType	This parameter is unused.

Returns

Returns STATUS_SUCCESS if the operations have been completed successfully and that the security descriptor has been assigned to the new object. STATUS_NO_TOKEN is returned if the caller hasn't supplied a valid argument to a security subject context. STATUS_INVALID_OWNER is returned if the caller hasn't supplied a parent descriptor that belongs to the main user (owner). STATUS_INVALID_PRIMARY_GROUP is returned by the same reason as with the previous NTSTATUS code. The two NTSTATUS codes are returned if the calling thread stated that the owner and/or group is defaulted to the parent descriptor (SEF_DEFAULT_OWNER_FROM_PARENT and/or SEF_DEFAULT_GROUP_FROM_PARENT respectively). STATUS_INSUFFICIENT_RESOURCES is returned if memory pool allocation for the descriptor buffer has failed. A failure NTSTATUS is returned otherwise.

Parameters

[in]	ParentDescriptor	A security descriptor of the parent object that is being created.
[in]	ExplicitDescriptor	An explicit security descriptor that is applied to a new object.
[out]	NewDescriptor	The new allocated security descriptor.
[in]	IsDirectoryObject	Set this to TRUE if the newly created object is a directory object, otherwise set this to FALSE.
[in]	SubjectContext	Security subject context of the new object.
[in]	GenericMapping	Generic mapping of access mask rights.
[in]	PoolType	This parameter is unused.

Returns

See SeAssignSecurityEx.

Parameters

[in]	SecurityDescriptor	A security descriptor.
[out]	QuotaInfoSize	The returned quota size of the given security descriptor to the caller. The function may return 0 to this parameter if the descriptor doesn't have a group or a discretionary access control list (DACL) even.

Returns

Returns STATUS_SUCCESS if the quota size of a security descriptor has been computed successfully. STATUS_UNKNOWN_REVISION is returned if the security descriptor has an invalid revision.

Insert an IRP into the CSQ.

Parameters

		_Inout_ PIRP	Irp,
		_Out_opt_ PIO_CSQ_IRP_CONTEXT	Context,

	)

Insert an IRP into the CSQ, with additional tracking context.

Parameters

Csq	- Pointer to the initialized CSQ
Irp	- Pointer to the IRP to queue
Context	- Context record to track the IRP while queued
InsertContext	- additional data that is passed through to CsqInsertIrpEx

Note

• Passes the additional context through to the driver-supplied callback, which can be used with more sophistocated queues
• Marks the IRP pending in all cases
• Guaranteed to not queue a canceled IRP
• This is complicated logic, and is patterend after the Microsoft library. I'm sure I have gotten the details wrong on a fine point or two, but basically this works with the MS-supplied samples.

         * an IRP that isn't in its queue.
         *
         * There are three possibilities:
         * 1) We get an IRP, we queue it, and it is valid the whole way
         * 2) We get an IRP, and the IO manager cancels it before we're done here
         * 3) We get an IRP, queue it, and the IO manager cancels it.
         *
         * #2 is is a booger.
         *
         * When the IO manger receives a request to cancel an IRP, it sets the cancel
         * bit in the IRP's control byte to TRUE.  Then, it looks to see if a cancel
         * routine is set.  If it isn't, the IO manager just returns to the caller.
         * If there *is* a routine, it gets called.
         *
         * If we test for cancel first and then set the cancel routine, there is a spot
         * between test and set that the IO manager can cancel us without our knowledge,
         * so we miss a cancel request.  That is bad.
         *
         * If we set a routine first and then test for cancel, we race with our completion
         * routine:  We set the routine, the IO Manager sets cancel, we test cancel and find
         * it is TRUE.  Meanwhile the IO manager has called our cancel routine already, so
         * we can't complete the IRP because it'll rip it out from under the cancel routine.
         *
         * The IO manager does us a favor though: it nulls out the cancel routine in the IRP
         * before calling it.  Therefore, if we test to see if the cancel routine is NULL
         * (after we have just set it), that means our own cancel routine is already working
         * on the IRP, and we can just return quietly.  Otherwise, we have to de-queue the
         * IRP and cancel it ourselves.
         *
         * We have to go through all of this mess because this API guarantees that we will
         * never return having left a canceled IRP in the queue.

IoCsqRemoveNextIrp - Removes the next IRP from the queue.

Parameters

Csq	- Queue to remove the IRP from
PeekContext	- Identifier of the IRP to be removed

Returns

Pointer to the IRP that was removed, or NULL if one could not be found

Note

• This function is sensitive to yet another race condition. The basic idea is that we have to return the first IRP that we get that matches the PeekContext >that is not already canceled<. Therefore, we have to do a trick similar to the one done in Insert above.
