这几天思索了一下需求，在脑中构思出了重定向IO的具体解决办法。这里采用python的subprocess模块起两个个进程跑这两个后端，通过Linux管道机制来实现两个后端的交互。（每次在外面恰饭都是大鱼大肉，，我想吃青菜啊😭😭）

This is a white-box fuzzing libxml2 v2.9.2 challenge[1] to reproduce CVE-2015-8317[2]

Congrats to QuiHao by the way, a brand new qemu 0day Orzzzz!!!

After all these frustrations due to the virus, I finally get back on the right track. American fuzzy lop (AFL) is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary.

Challenges are well-designed, deliberately constructed, leading to specific ways to solve them, which is actually further and further away from real world exploits. I started to aim more at Linux kernel memory allocator these days and gathered some imformation about Buddy System & SLUB hitherto.

Like user mode, there are also couples of ways of mitigation against exploits in Linux kernel. Here is a list of mitigation in kernel mode and methods to bypass some of them.
