Extracts C++ class runtime information from an arm64 Darwin kernel.
Class names, inheritance, vtables, methods, etc.
Should be simple enough:
make
Links against CoreFoundation and IOKit though, so probably only works on Darwin platforms.
Run with no arguments for exhaustive help.
Examples:
iometa kernel # List all classes
iometa -a kernel # List all classes with more info
iometa -A kernel # List all classes and print all virtual methods
iometa -AC IOSurfaceRoot kernel # Print info and methods of class IOSurfaceRoot
iometa -Ae IOSurfaceRoot kernel # Print info and methods of all classes extending IOSurfaceRoot
iometa -Ap IOSurfaceRoot kernel # Print info and methods of all classes from which IOSurfaceRoot inherits
iometa -AB com.apple.iokit.IOSurface kernel # Print info and methods of classes from kext com.apple.iokit.IOSurface
iometa -M kernel >map.txt # Create symbol map
iometa -A kernel map.txt # List all classes with virtual methods, and resymbolicate them
iometa -R kernel map.txt # Generate a radare2 script file with all symbols
For more info on symbol maps and resymbolication, see /sym.
