  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
