Verifying Application Startup on Linux

Michel von Czettritz

This talk will look at how we can ensure that a user space application was started successfully. We will provide an overview of how an application is started, looking at the glibc and the Linux kernel. Then we'll identify potential problems which could affect the application startup, both at application startup time and at build time. And finally we'll present our solutions to the identified problems, including ensuring memory integrity and unwanted interactions from the rest of the kernel.
