Let's write a Debugger!

Ever wondered how does the ever-famous gdb tool work? How do breakpoints work? How does single stepping work? All tools that you may use in day-to-day life, but do you actually know how they work? During this talk, we will deepdive into the numerous tools Linux exposes that you can use to check and modify the state of another running process. Of course, most of it wouldn't be possible with just Linux support, so we will also have a brief look at the available hardware support. Think debug registers and special interrupts. By the end of this talk, hopefully you will walk away with a refreshed knowledge of the interesting world of debuggers.

This talk was given at Linux.conf.au 2018 (LCA2018) which was held on 22-26 January 2018 in Sydney Australia.

linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source.
