Figure 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.

Whether municipal solid waste can be treated by incineration technology depends on the combustible content, low heating value and moisture content of the waste. Generally, the combustible composition of domestic waste is above 30% ~ 40%, the low heating value is above 3350 kJ/kg, the moisture content of the waste is below 50%, and the waste can be incinerated spontaneously. However, under this condition, the waste incineration cannot meet the requirement of 850 ℃/2S for flue gas in the furnace. The low heating value of domestic waste is above 6280 kJ/kg, which can realize stable combustion. It can not only meet the requirement of 850 ℃/2S flue gas in the furnace, but also meet the need of working medium power generation, effectively utilize energy and build a waste incineration power plant.
Note that all I/O operations (including accept (), read (), write (), and connect () operations of I/O) are still completed in the Reactor thread (mainReactor thread or subReactor thread). The Thread Pool is only used to handle logic for non-I/O operations.
