为解决Linux内核中Berkeley Packet Filter(BPF)验证器存在缺陷，导致恶意BPF程序可能绕过静态检查并获取内核内存未授权访问的问题，研究人员开展了MOAT主题研究。该研究提出了一种利用Intel MPK和Arm Stage-2等硬件特性实现的两层内存隔离方案，旨在将BPF程序与内核进行 ...

I have been trying to implement a packet sniffer on QNX to read outgoing UDP packets for a software unit test. As far as I am aware, it isn't possible to create a raw socket and set it promiscuous ...
