How do you debug a kernel?
Setup
- Build the kernel with CONFIG_GDB_SCRIPTS enabled, but leave CONFIG_DEBUG_INFO_REDUCED off.
- Install that kernel on the guest, turn off KASLR if necessary by adding “nokaslr” to the kernel command line.
- Enable the gdb stub of QEMU/KVM, either.
- cd /path/to/linux-build.
- Start gdb: gdb vmlinux.
- Attach to the booted guest:
How to specify a KDbg address for volatility?
VOLATILITY_KDBG – Specifies a KDBG address. See EXTRA PROCEDURES to more details. Other plugin flags may be utilized in this way, for example KPCR, DTB or PLUGINS. When exporting variables, simply prefix VOLATILITY_ before the flag name (e.g. VOLATILITY_KPCR).
Which is better ImageInfo or kdbgscan for volatility?
As opposed to imageinfo which simply provides profile suggestions, kdbgscan is designed to positively identify the correct profile and the correct KDBG address (if there happen to be multiple). This plugin scans for the KDBGHeader signatures linked to Volatility profiles and applies sanity checks to reduce false positives.
