这次007对手是臭名昭著的国际恐怖分子雷纳德。为了垄断石油供给权，雷纳德杀害了石油大亨罗伯爵士，当然他也不会放过罗伯爵士的继承人——美丽的依蕾克屈，这个狂人甚至威胁说要在土耳其巨大的输油管道里引发核爆炸。于是007必须驾着高速快艇从西班牙比尔堡的奈维河岸到伦敦的泰晤士河边，再穿越苏格兰的高地，冒着几乎不可能生还的危险去保护罗伯爵士队唯一继承人、粉碎雷纳德的阴谋。连场大战一触即发！Half-connection survival time: refers to the longest survival time of entries in the half-connection queue, that is, the longest time from receiving SYN packet to confirming that this message is invalid. This time value is the sum of the longest waiting time of all retransmission request packets. Sometimes we also call the half connection survival time Timeout time and SYN_RECV survival time.2.5. 4.2Figure 1 is an example of a JOP attack. In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.就你小嘴甜，也不怕你舅舅吃味？说笑几句，子夜的情绪好了很多。"Great! Grandma, this Christmas tree is so beautiful!"
