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.

Opens a token that is tied to a thread handle.

Parameters

[out]	ThreadHandle	Thread handle where the token is about to be opened.
[in]	DesiredAccess	The request access right for the token.
[in]	OpenAsSelf	If set to TRUE, the access check will be made with the security context of the process of the calling thread (opening as self). Otherwise the access check will be made with the security context of the calling thread instead.
[out]	TokenHandle	The opened token handle returned to the caller for use.

Returns

See NtOpenThreadTokenEx.

		_In_ ACCESS_MASK	DesiredAccess,
		_In_ BOOLEAN	OpenAsSelf,
		_In_ ULONG	HandleAttributes,
		_Out_ PHANDLE	TokenHandle
	)

Opens a token that is tied to a thread handle.

Parameters

[out]	ThreadHandle	Thread handle where the token is about to be opened.
[in]	DesiredAccess	The request access right for the token.
[in]	OpenAsSelf	If set to TRUE, the access check will be made with the security context of the process of the calling thread (opening as self). Otherwise the access check will be made with the security context of the calling thread instead.
[in]	HandleAttributes	Handle attributes for the opened thread token handle.
[out]	TokenHandle	The opened token handle returned to the caller for use.

Returns

Returns STATUS_SUCCESS if the function has successfully opened the thread token. STATUS_CANT_OPEN_ANONYMOUS is returned if a token has SecurityAnonymous as impersonation level and we cannot open it. A failure NTSTATUS code is returned otherwise.

PsChargePoolQuota()

NTKERNELAPI VOID NTAPI PsChargePoolQuota	(	_In_ PEPROCESS	Process,
		_In_ POOL_TYPE	PoolType,
		_In_ SIZE_T	Amount
	)

Charges the pool quota of a given process. The kind of pool quota to charge is determined by the PoolType parameter.

Parameters

[in]	Process	The process which quota is to be charged.
[in]	PoolType	The pool type to choose to charge quotas (e.g. PagedPool or NonPagedPool).
[in]	Amount	The amount of quotas to charge into a process.

Returns

Nothing.

Remarks

The function raises an exception if STATUS_QUOTA_EXCEEDED status code is returned. Callers are responsible on their own to handle the raised exception.

Charges the non paged pool quota of a given process.

Parameters

[in]	Process	The process which non paged quota is to be charged.
[in]	Amount	The amount of quotas to charge into a process.

Returns

Returns STATUS_SUCCESS if quota charing has suceeded, STATUS_QUOTA_EXCEEDED is returned otherwise to indicate the caller attempted to charge quotas over the limits.

Parameters

[in]	Process	The process which paged quota is to be charged.
[in]	Amount	The amount of quotas to charge into a process.

Returns

Returns STATUS_SUCCESS if quota charing has suceeded, STATUS_QUOTA_EXCEEDED is returned otherwise to indicate the caller attempted to charge quotas over the limits.
