r2m2's Issues

Specify the bits parameter from the command line

Currently, r2m2 only works on 32 bits architectures. That can be modified in the plugins:

.bits = 16|32|64,

Fix the docker example

After opening /bin/ls the architecture is switched to x86 by r2:

docker run --rm -it -e 'R2M2_ARCH=x86_64' guedou/r2m2
 -- Are you a wizard?
[0x00000000]> e~arch
anal.arch = r2m2
[..]
[0x00000000]> o /bin/ls
4
[0x0000487f]> e~arch
anal.arch = x86
[..]

Also, there is an OverflowError on the first call.

Error during the compilation

Dear developers,

Good morning. How are you?

Unfortunately, I haven't gotten correctly compiling the r2m2 as shown below:

root@ubuntu1:~/r2m2# make all install

python tools/gen_includes.py /usr/include/libr
python tools/cffi_miasm.py r2m2_ad

Makefile:47: recipe for target 'miasm_embedded_r2m2_ad.c' failed
make: *** [miasm_embedded_r2m2_ad.c] Error 1

This error occurs using Ubuntu 16.04.1 and Kali Linux 2018. The same error also happen when I tried do build the docker using "docker build -t guedou/r2m2 .". All requirements (radare2, miasm, cffi, pycparser and jinja2) are installed.

Additionally, I've tried changing the cffi and pycparser versions, but I've gotten the same error.

I hope you have an amazing day.

Alexandre.

tell in the doc if the win32 api is supported

I was using r2m2 because I was looking for a tool to emulate PEB and win32 api from r2 command line.

Does r2m2 answer to my issue? Is it implemented?

best regards.

r2m2 arch not present yet

docker run -v "$(pwd)":/home/r2m2 --rm -it -e 'R2M2_ARCH=x86_64' guedou/r2m2 bash

[r2m2@90280a71d3a6 ~]$ rasm2 -L | grep r2m2
[r2m2@90280a71d3a6 ~]$

Create the r2pm package

r2pm -i r2m2

uninstall is incomplete

The miasm_embedded_r2m2_* files are not removed.

Current r2m2 roadmap

From highest to lowest priority:

• Travis: add OS X support
• build and publish a docker image on https://hub.docker.com
• create an asciinema video
• improve the README
• update the docker hub description
• create a demo VM on https://dply.co/
• add examples/
• add a Python only r2 ad plugin into examples/
• remove docker pull in Dply script
• add a link to https://guedou.github.io + fix miasm link
• add support for calling conventions
• cache the miasm Machine object
• miasm_asm(): asm then dis to compare the result
• move Python code into a dedicated Python module
• add a requirements.txt file and use pip
• install using r2pm
• better miasm2 expressions type checking in Ae
• detect dependencies with make
• log into r2m2.log & use the R2M2_LOG env variable
• support user-defined Python module
• use brew on OS X
• push the docker image from Travis

The analyze () function is called more than once per instruction. This slows done r2m2 =/
