Lists links to client block hook functions , allocation hook functions , allocation hooks and crt memory allocations , and report hook functions 列出指向客戶端塊掛鉤函數(shù)、分配掛鉤函數(shù)、分配掛鉤和crt內(nèi)存分配以及報告掛鉤函數(shù)的鏈接。
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 鏈接到用于c運行時庫的調(diào)試技術(shù),包括:使用crt調(diào)試庫、用于報告的宏、 malloc和_ malloc _ dbg之間的差異、編寫調(diào)試掛鉤函數(shù)以及crt調(diào)試堆。
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 針對常見的ip地址欺騙、 ip源路由欺騙、 icmp重定向欺騙、 ip劫持等網(wǎng)絡(luò)攻擊給予了分析并在過濾管理模塊中給出了防御的方法,其中ip劫持防御是用一個鉤子函數(shù)注入?yún)f(xié)議棧中來實現(xiàn)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 該模塊以字符設(shè)備文件的形式為應(yīng)用程序提供接口,并在netfilter框架為ipv4定義的nf _ ip _ pre _ routing鉤子上掛接了一個鉤子函數(shù),該鉤子函數(shù)實現(xiàn)bpf虛擬機(jī),完成對數(shù)據(jù)包的捕獲;最后,本文對mybpf模塊作了相應(yīng)的測試并與在sock _ packet套接口上實現(xiàn)的bpf做了性能比較。
