    • A method, a device, and a system for realizing kernel online patching are provided. The method includes loading a pre-generated patch file in an operating system, setting a first breakpoint at an execution start position of the primitive function when a system thread executes the primitive function and a breakpoint exception occurs during the thread execution process due to the first breakpoint, modifying a returning execution address of the first breakpoint into the destination address of the patch function corresponding to the primitive function according to the first corresponding relation, and removing the first breakpoint. The kernel online patching implementation has a small impact on the normal operation of the operating system. The patch function becomes valid without restarting the operating system, thereby satisfying the high reliability requirements of carrier-class products.
    • 提供了一种实现内核在线修补的方法,设备和系统。 该方法包括在操作系统中加载预生成的补丁文件,当系统线程执行原始函数时,在原始函数的执行开始位置设置第一个断点,并且在线程执行过程期间发生断点异常,这是由于第一个 断点,根据第一对应关系将第一断点的返回执行地址修改为对应于原语函数的补丁函数的目的地地址,以及去除第一断点。 内核在线修补实现对操作系统的正常运行影响很小。 补丁功能无效,无需重新启动操作系统,从而满足电信级产品的高可靠性要求。

    • A service gateway includes a fast path module for processing data packets without using packet buffers and a normal path module for processing data packets using packet buffers. The fast path module receives a service request data packet from a client side session, determines that the service request data packet cannot be processed by the fast path module, and in response, sends the service request data packet to the normal path module. After receiving the service request data packet, the normal path module retrieves a first proxy session record created by the fast path module, where the first proxy session record is associated with a client session record for the client side session, creates a second proxy session record based on the service request data packet and the client session record, and processes the service request data packet according to the second proxy session record.
    • 服务网关包括用于处理数据分组而不使用分组缓冲器的快速路径模块和用于使用分组缓冲器来处理数据分组的正常路径模块。 快速路径模块从客户端会话接收服务请求数据包,确定服务请求数据包不能被快速路径模块处理,响应时间将服务请求数据包发送到正常路径模块。 在接收到服务请求数据分组之后,正常路径模块检索由快速路径模块创建的第一代理会话记录,其中第一代理会话记录与客户端会话的客户端会话记录相关联,创建第二代理会话记录 基于所述服务请求数据分组和所述客户端会话记录,并根据所述第二代理会话记录处理所述服务请求数据分组。

    • Embodiments of the present invention provide a method, a device and a system for activating an on-line patch. The method comprises: positioning an address of a patch function and an entry address of a to-be-patched function; writing, in a middle segment, a long-jump instruction for jumping to the patch function based on the address of the patch function and the entry address of the to-be-patched function, where the middle segment is a storage space, which is located before or after the entry position of the to-be-patched function and can at least store one long-jump instruction; and modifying an instruction at the entry position of the to-be-patched function to a short-jump instruction for jumping to the middle segment, so as to jump to the middle segment after the short jump instruction is executed, and then to jump to and execute the patch function through that instructions in the middle segment are executed.
