At present, what methods do we take to solve the attack? The first method shortens the waiting time and deletes the illegal request data packets waiting in the waiting queue as soon as possible. The second method is that the first handshake message is not put into the waiting queue. We return a 32-bit unsigned integer to the client as the Seq of the second handshake. The integer is obtained by adding a serial number of the server to the parameters requested by the user (including the requested address, port, etc.). If it is a normal user, it adds 1 as ACK after receiving this integer and returns it to the server. After receiving the data, the server subtracts 1 from this ACK and then performs inverse operation to obtain various parameters. Finally, the data sent out are compared. If they are completely consistent, it means that it is an effective response and stored in the corresponding data structure, otherwise it is not. Through this method, illegal requests cannot occupy system resources.Only when the taskAffinity matches the SingleTask startup pattern will the startup activity run on the same task stack as the taskAffinity.圣诞节后，罗恩度过了一个并不愉快但却十分新奇的生日。这时，伏地魔出现了，这次他竟然杀死了海格的宠物阿拉格格，小伙伴们为这只蜘蛛举办了盛大的葬礼。狮王（郑伊健 饰）、火山（陈小春 饰）、Bill（谢天华 饰）、淡定（钱嘉乐 饰）、老鼠（林晓峰 饰）五个出生入死的兄弟，在恩师曹sir（曾志伟 饰）的带领下，为了救济儿童而偷取特效药，却惨遭设局，陷入枪林弹雨的险境之中。兄弟们抱着视死如归的豪情，展开一连串的追查与激战。他们明白，即使无法活着回来，也比一人活着痛快！哦，对了，网站服务器也别用你们学校里的了。(未完待续……) show_style();。
