10[$] Writing network flow dissectors in BPF null/LWN/0000764200 70\r

4i Network packet headers contain a great deal of information,\r
5i but the kernel often only needs a subset of that information\r
6i to be able to perform filtering or associate any given packet\r
7i with a flow. The piece of code that follows the different\r
8i layers of packet encapsulation to find the important data is\r
9i called a flow dissector. In current Linux kernels, the [1]flow\r
10i dissector is written in C. A [2]patch set has been proposed\r
11i recently to implement it in BPF with the clear goal of\r
12i improving security, flexibility, and maybe even performance.\r
