    • Performing security sensitive operations with an application security model. Security agnostic code is executed. The security agnostic code is identified as not having authorization to perform a security sensitive operation. Executing the security agnostic code includes calling code identified as security safe critical code. In response to the security agnostic code calling the security safe critical code, the security safe critical code is executed. The security safe critical code includes functionality for performing validity checks. Executing the security safe critical code includes performing an validity check for the security agnostic code. When the security agnostic code passes the validity check, code identified as security critical code is called. In response to the security safe critical code calling the security critical code, the security critical code is executed. The security critical code is authorized to perform the security sensitive operation.
    • 使用应用程序安全模型执行安全敏感操作。 执行安全不可知代码。 安全性不可知代码被识别为没有执行安全敏感操作的授权。 执行安全性不可知代码包括调用被标识为安全关键代码的代码。 响应安全隐私代码调用安全安全关键代码,执行安全安全关键代码。 安全关键代码包括执行有效性检查的功能。 执行安全安全关键代码包括对安全性不可知代码执行有效性检查。 当安全不可知代码通过有效性检查时,称为安全关键代码的代码。 响应安全关键代码调用安全关键代码,执行安全关键代码。 授权安全关键代码执行安全敏感操作。

    • A system and method is provided to facilitate communications between object systems. A caller is provided having optimized in-lined functionality when initiating a remote function call between managed and unmanaged object systems, for example. The in-lined functionality includes utilizing direct calls and returns within a calling function. In this manner, pushing additional arguments onto an execution stack because of an external stub reference is mitigated. In addition, one or more code loops can be analyzed to enable stack markers to be “hoisted” and thus pushed a single time instead of each time the calling function executes. Other aspects of the optimized caller provide garbage collection and thread management, security attribute checking on outgoing calls, calling convention considerations, wherein arguments and return values are organized according to the convention utilized by the remote object system, and in-lined marshalling to provide enhanced performance over external stub code references. Code extensibility options can be included enabling functions to be generalized thereby insulating object systems from implementation details of the called functions.
    • 提供了一种系统和方法来促进对象系统之间的通信。 例如,在启动被管理对象系统和非托管对象系统之间的远程函数调用时,提供一个具有优化内嵌功能的调用者。 嵌入式功能包括在调用功能中使用直接调用和返回。 以这种方式,由于外部存根引用将附加参数推送到执行堆栈得到缓解。 此外,可以分析一个或多个代码循环,以使堆栈标记“挂起”,从而推动一次,而不是每次调用函数执行。 优化的呼叫者的其他方面提供垃圾收集和线程管理,对呼出的呼叫的安全属性检查,调用惯例注意事项,其中参数和返回值根据远程对象系统使用的惯例进行组织,并且内联编组以提供增强的 对外部存根代码引用的性能。 可以包括代码可扩展性选项,使得功能得以泛化,从而将对象系统与被调用函数的实现细节隔离。
