ida-kallsyms

IDA script for parsing kallsyms.

Usage

• git clone https://github.com/mephi42/ida-kallsyms.git
• Open the kernel in IDA, let the autoanalysis finish.
• From File → Script file... (Alt+F7 / Alt+F9) run ida-kallsyms/ida-kallsyms.py script.

Usage with Ghidra

• git clone https://github.com/mephi42/ida-kallsyms.git
• Open the kernel in Ghidra, let the autoanalysis finish.
• Go to Window → Script manager.
• Once: press Script Directories button and add ida-kallsyms.
• In Filter edit box, type kallsyms.
• Double-click ghidra-kallsyms.py and wait.

Stand-alone usage

• git clone https://github.com/mephi42/ida-kallsyms.git
• ida-kallsyms/find-kallsyms vmlinux >vmlinux.kallsyms
• The resulting vmlinux.kallsyms file can be imported into IDA using ida-kallsyms-import.py script.

build-vmlinux

Script for obtaining function signatures and struct layouts. Works by building a Linux Kernel that is similar to the one being analyzed and extracting debug information from it.

Usage

• Load kallsyms into IDA as described above.

• ida-kallsyms/build-vmlinux --like vmlinux

  This will run for a while and generate vmlinux.like.json file.

  Check out ida-kallsyms/build-vmlinux --help in case you already have binutils-gdb / gcc / linux local git repos or a .config that matches vmlinux.

• Import vmlinux.like.json into IDA using ida-kallsyms/ida-like-import.py script.

• If there are import errors, check vmlinux.like.json.log file.
