Lists links to client block hook functions , allocation hook functions , allocation hooks and crt memory allocations , and report hook functions 列出指向客户端块挂钩函数、分配挂钩函数、分配挂钩和crt内存分配以及报告挂钩函数的链接。
Links you to debugging techniques for the c run - time library , including using the crt debug library , macros for reporting , differences between malloc and malloc dbg , writing debug hook functions , and the crt debug heap 链接到用于c运行时库的调试技术,包括:使用crt调试库、用于报告的宏、 malloc和_ malloc _ dbg之间的差异、编写调试挂钩函数以及crt调试堆。
Common network attacks such as ip spoofing , source route spoofing , icmp redirect deception and ip hijack are analyzed and protected by filter manage module . . ip hijack protection is implemented through injecting a hook function into protocol stack in detail 针对常见的ip地址欺骗、 ip源路由欺骗、 icmp重定向欺骗、 ip劫持等网络攻击给予了分析并在过滤管理模块中给出了防御的方法,其中ip劫持防御是用一个钩子函数注入协议栈中来实现的。
Secondly , we implement a bpf model called mybpf on linux as a kernel module . it can collect packets within the netfilter frame , provide the applications with an interface in char device file manner and be attached to the nf _ ip _ pre _ routing hook defined by netfilter frame for ipv4 as a hook function . finally , we evaluate the performance between mybpf and other bpf on sock _ packet socket 该模块以字符设备文件的形式为应用程序提供接口,并在netfilter框架为ipv4定义的nf _ ip _ pre _ routing钩子上挂接了一个钩子函数,该钩子函数实现bpf虚拟机,完成对数据包的捕获;最后,本文对mybpf模块作了相应的测试并与在sock _ packet套接口上实现的bpf做了性能比较。
