我需要尽快完成这件事。另外,我工作的数字是用Grey Code表示的.就为了把它扔进去。那么,在MIPS中是否有一些伪指令来确定“数字”的奇偶性,或者我必须手动完成?如果没有MIPS指令(这似乎不太可能),有什么建议如何手动完成吗?后续:我发现了一个优化,但我的实现 浏览21提问于2010-04-11得票数 1 回答已采纳 1回答 如何在寄存器中存储基2号?
需要调用Sleep来让shellcode从数据Cache刷新到指令Cache,否则会执行失败,不能像x86架构下直接跳转到shellcode,而是需要构造一条ROP链接,先调用sleep,然后在跳转到shellcode。 栈溢出实例 还是用我们一开始的vuln程序进行溢出 qemu运行 qemu-mipsel-g9000vulnaaaaaa gdb远程调试 $ qemu-mipsel -g9000vuln $ gdb-multiar...

If src is a string that is not a register, then it will locally set context.arch to ‘mips’ and use pwnlib.constants.eval() to evaluate the string. Note that this means that this shellcode can change behavior depending on the value of context.os. Parameters: dst (str)– The destinat...
