John Baldwin - Introduction to Debugging the FreeBSD Kernel
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
