fixenv

A script to make stack addresses the same when running a program under gdb,ltrace,strace or without debugging (without ASLR of course). Env variables order is saved too.

Usage

<pre> Usage: ./r.sh getvar [var_name] - get address of envvar's value ./r.sh dump [start_addr [size]] - dump the end of the stack Running programs: ./r.sh ./program - run program ./r.sh strace ./program - run program in strace ./r.sh ltrace ./program - run program in ltrace ./r.sh gdb ./program [arg1 [arg2 [ ... ]]] - run program in gdb </pre>

Example

<pre> $ ./r.sh gdb test/test ... Local var: 0xbffffa5c Env vars: 0xbffffc5f SHELL=/bin/bash ... $ ./r.sh strace test/test 2>/dev/null Local var: 0xbffffa5c Env vars: 0xbffffc5f SHELL=/bin/bash ... $ ./r.sh test/test Local var: 0xbffffa5c Env vars: 0xbffffc5f SHELL=/bin/bash $ export XYZ=SOMEDATA $ ./r.sh getvar XYZ 0xbffffcb8 \xb8\xfc\xff\xbf (XYZ) $ ./r.sh test/test | grep XYZ 0xbffffcb4 XYZ=SOMEDATA </pre>
