[svlug-announce] SVLUG Jan. 31st meeting: Michael Kerrisk on Understanding User Namespaces

WHEN:

Wednesday, January 31st, 2018
7 - 8:30pm



MAIN PRESENTATION

TOPIC: Understanding User Namespaces 

PRESENTED BY: Michael Kerrisk



TOPIC SUMMARY:


User namespaces are at the heart of many interesting technologies that
allow isolation and sandboxing of applications, for example, running
containers without root privileges, and sandboxes for Web browser
plug-ins. In this presentation, we'll take a closer look at user
namespaces, building up a basic understanding of what a user namespace
is, and going on to questions such as: what does being "superuser inside
a user namespace" allow you to do (and what does it not allow); what is
the relationship between user namespaces and other namespace types (PID,
UTS, network, etc.); and what are the security implications of user
namespaces? We'll also explore some simple shell commands that can be
used for creating and experimenting with user namespaces, in order to
better understand how they work. We'll conclude with a brief survey of
some use cases for user namespaces.
