Wireshark (formerly known as Ethereal) is a very popular open-source network traffic analysis software.
Wireshark 1.8.0-1.8.3 has a security vulnerability in the implementation of the sFlow parser. By enticing victims to read malicious packets, the
Rd and RT (mpls vpn bgp)
Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is implemented, whether the PE device can achieve

Call in the thread function. This thread releases the MCU. If there are other tasks with the same priority in the waiting status, the right to use the MCU is obtained.
Giving a thread out is an opportunity for the OS to schedule tasks.
Create two threads and observe their results:

At the same time, the thread is in the ready state and runs first with a higher priority.
When a high-priority task is ready, the low-priority task gives way to the CPU, so that the high-priority task is executed first.
