System
SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.
After the investigation of the case, many investors would like to know the progress of the case, the proportion of stolen goods recovered, how much the funds can be repaid, and whether some of them can be returned first... The police prompt the release of information, and remember that it is generally released by the organizer and must not listen to gossip. Because the interests of the investment group are numerous and complicated, some people with ulterior motives will deliberately distort the facts or make trouble to achieve their own interests or other ulterior purposes. What's more, under the name of "defending rights in groups", groups are set up to collect fees for entering groups. After that, group owners mobilize everyone to raise funds and hire lawyers. As long as everyone pays 100 yuan, there is hope that they will get back their hard-earned money. As a result, when the group owners have collected their capital, they will ban everyone and then T off everyone. Other members pretended to be data collectors and asked everyone to fill in the data. As a result, they sold the data, causing secondary injuries.

Finally, if there are any considerations or mistakes in the article, please leave a message to discuss them. In addition, for the source code, this paper only gives the analysis of the distribution process. The consumption process will no longer be analyzed in detail. To provide an idea, There is a line of comments in the source code analysis in this article. Readers can start here to look at consumption-related codes. Note that this is the dispatchTouchEvent () in the ViewGroup class. Under this line of comments, there will be relevant logic calling the method of dispatchTransformedTouchEvent () (also called to this method by the distribution process). This method will have such code calling the dispatchTouchEvent () in the View, the parent class of the ViewGroup class. Then look at the dispatchTouchEvent () in the View, and you will find that onTouchEvent () is called. At the same time, you will also find some other things, such as the priority of onTouchListener () and onTouchEvent ().
