摘要： Methods and apparatus are described herein to manage a serving cell change. A HS-SCCH monitored set is maintained to store entries for all pending serving cell change requests. The HS-SCCH for each entry is monitored for a timer period. Once a change request has been confirmed for one entry, monitoring for the other entries continues until expiration of the associated timers.

摘要： A method of purging cached open files from a client-side delayed close list on a remote file system. The remote file system stores a unique file identifier for each cached open file which is independent of the cached file's namespace. In response to a delete or rename command of a remote target file, the remote file system obtains a target file identifier from the target file's server. The remote file system then compares the target file identifier with each of the cached file's unique file identifier. If a cached file's unique file identifier matches the target file identifier, the cached file is purged from the delayed close list.

摘要翻译： 从远程文件系统上的客户端延迟关闭列表中清除缓存的打开文件的方法。 远程文件系统为每个缓存的打开文件存储唯一的文件标识符，该文件独立于缓存文件的命名空间。 响应于远程目标文件的删除或重命名命令，远程文件系统从目标文件的服务器获取目标文件标识符。 然后，远程文件系统将目标文件标识符与每个缓存文件的唯一文件标识符进行比较。 如果缓存文件的唯一文件标识符与目标文件标识符匹配，则缓存文件将从延迟关闭列表中清除。

摘要： A method, apparatus, and computer readable medium are provided by aspects of the present invention to determine whether a malware is resident on a host computer. In one embodiment, a method determines whether data that is characteristic of malware is loaded in the system memory of a host computer. More specifically, the method includes causing a device communicatively connected to a host computer to issue a request to obtain data loaded in the system memory. Then, when the requested data is received, a determination is made regarding whether the data is characteristic of malware. Since, the method causes data to be obtained directly from system memory without relying on software services on the host computer, malware that employs certain stealth techniques will be identified.

摘要： Embodiments of a RootKit detector are directed to identifying a RootKit on a computer that is designed to conceal malware. Aspects of the RootKit detector leverage services provided by kernel debugger facilities to automatically obtain data in specified data structures that are maintained by an operating system. Then the data obtained from the kernel debugger facilities is processed with an integrity checker that determines whether the data contains properties sufficient to declare that a RootKit is resident on the computer.

摘要： An opportunistic directory cache and method of usage reduce the number of calls between a client and server for file information, reducing the wastage of network resources and server resources. The expirable directory cache can be refreshed any time an appropriate directory enumeration call is made to the server, and is capable of being partially rather than completely invalidated in response to an indication that the file information of a file listed in the cache has or will change. If the affected file is identifiable, the entry in the cache for that file is invalidated, i.e. it is no longer useful for serving file information. If the affected file is not identifiable, then a first character projection of the file name is invalidated in the cache. In this manner, the directory cache is maintained with minimum resources and is persisted to the greatest extent possible, increasing its likelihood of usefulness.

摘要： The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

摘要翻译： 本发明提供了一种新颖的客户端缓存（CSC）基础设施，其支持目录级别的转换状态，以促进跨客户端和远程服务器之间的连接状态的无缝操作。 更具体地，执行持续高速缓存以跨连接中断和/或带宽改变来保护用户（例如，客户端）和/或客户端应用。 这部分是通过将客户端数据存储器连同适当的文件访问参数一起缓存所需的文件来实现的。 此外，客户端在断开连接期间保持对缓存文件的访问。 此外，路径的一部分可以离线，而上游的其他部分可以保持联机。 CSC在与物理路径上运行的DFS协作的逻辑路径上运行，以跟踪缓存，访问和更改目录中的文件。 此外，无论文件副本是否存在冲突，客户端上的真相都是有利的。
