In this post, I’m going to introduce you to the concept of Linux network namespaces. So what are network namespaces? Generally speaking, an installation of Linux shares a single set of network interfaces and routing table entries. Network namespaces change that fundamental assumption.

The programmer uses it to work with memory buffers, files, network sockets, system time and more. The GNU C Library (glibc) is the most common open source C library and is used on most Linux systems. To this end, we constructed a fuzzer that calls all floating point functions with random (fuzzer-generated) input for GNU libc.
