8 Description: This simple extension provides bindings to the Linux unshare() syscall, added in kernel version 2.6.16
9
10 By using unshare(), new and interesting features of the Linux kernel can be exploited, such as:
11
12 * Creating a new network name space (CLONE_NEWNET)
13 * Creating a new file system mount name space (CLONE_NEWNS)
14 * Reverting other features shared from clone()
