debugger_scripts

Simple but convenient debugger scripts for Android and iOS debugging.

Installation

Installation scripts are in lldb_utilities.py and gdb_utilities.py. Please efer to the python file.

Features

gdb

1. display a range memory in xxd format

   xxd {addr} {size}
   

2. search the whole memory

   This command is just like the find command in gdb: https://sourceware.org/gdb/onlinedocs/gdb/Searching-Memory.html, except that it searches in the whole valid memory mappings.

   e.g.:

   full_search /b 0xff,0xff,0xff,0xfc
   

3. stop when library is loaded

   stop_at_load {libname}
   

   This is useful when you do an early trace that most libraries are not loaded yet. It's similar to the feature provided by IDA.

4. stop when file is opened

   stop_at_open {filename}
   

   After the file is opened, the fd will be printed for further using.

5. stop when file is read

   stop_at_read {fd}
   

   The fd is obtained from stop_at_open in the 4th feature.

lldb

1. display image mapping

   imlist {image_name}
   

   A very simple feature that only display the relavant image(s) by grep after calling image list
