Introduction to Debugging the FreeBSD Kernel
Just like every other piece of software, the FreeBSD kernel has bugs. Debugging a kernel is a bit different from debugging a userland program as there is nothing underneath the kernel to provide debugging facilities such as ptrace() or procfs. This paper will give a brief overview of some of the tools available for investigating bugs in the FreeBSD kernel. It will cover the in-kernel debugger DDB and the external debugger kgdb which is used to perform post-mortem analysis on kernel crash dumps.
Introduction to Debugging the FreeBSD Kernel
- Basic crash messages, what a crash looks like
- typical panic() invocation
- page fault example
- "live" debugging with DDB
- stack traces
- ps
- deadlock examples
- show lockchain
- show sleepchain
- Adding new DDB commands
- KGDB
- inspecting processes and threads
- working with kernel modules
- using scripts to extend
- examining crashdumps using utilities
- ps, netstat, etc.
- debugging strategies
- kernel crashes
- system hangs
- Basic crash messages, what a crash looks like
