In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).
For example, explain why the above points should be considered. If the event is passed to a View without child views, then the view's onTouchEvent () will be called back. We can decide whether to consume the event by overriding the return value of onTouchEvent (). If this event is down and onTouchEvent () returns false and does not consume it, then the events after the event sequence will no longer be distributed to this View. If the down event is consumed, then the subsequent events will continue to be distributed to this View. At this time, if a move event of the subsequent event is not consumed, then the events after this move event will still be distributed to this View.
