test-py-io.py example segfaults: invalid io->desc->plugin #187

Closed Wenzel closed 6 years ago

Wenzel commented 6 years ago

Hi,

I tried to create an IO plugin in Python, using the example provided at radare2-bindings/libr/lang/p/test-py-io.py.

However, the example segfaults:

$ r2 -I test-py-io.py pyio://3
Registering Python IO plugin...
True
python-check pyio://3
MyPyIO Opening pyio://3
[3]    14147 segmentation fault (core dumped)  r2 -I test-py-io.py pyio://3

A little debugging:

Reading symbols from r2...done.
(gdb) run -I test-py-io.py pyio://3

it crashes when the code tries to access io->desc->plugin->listener, since io->desc->plugin pointer value is 0x4d2, which is the value returned by the open function in the pyio plugin.

How can i create my RIODesc in Python and return the correct value ? Should we fix the example maybe ?

Thanks

Can you share valgrind or asan output?

valgrind

alias valgrind='valgrind -v --leak-check=full --show-reachable=yes --track-fds=yes --track-origins=yes --malloc-fill=42 --free-fill=43'

$ valgrind --log-file=valgrind.out r2 -I test-py-io.py pyio://3
Registering Python IO plugin...
True
python-check pyio://3
MyPyIO Opening pyio://3
[1]    26642 segmentation fault (core dumped)  valgrind -v --leak-check=full --show-reachable=yes --track-fds=yes     r2 -I

The file is too big (3.6M), i will share it on Google Drive.

ASAN

I found a script named asan.sh, and recompiled radare2:

$ r2 -I test-py-io.py pyio://3
Registering Python IO plugin...
True
[r] Cannot open 'pyio://3'

Why r u tracing memleaks? This is useless. Paste only the invalid memory accesses. So running valgrind qithout any option is enough

this iseems like a problem in python, not in r2.

maybe this is what happens when we use different dlsym flags, can you try reverting those in the previous state? (LOCAL -> GLOBAL) and see if thats the cause?

Hi,

I tried to create an IO plugin in Python, using the example provided at radare2-bindings/libr/lang/p/test-py-io.py.

However, the example segfaults:

$ r2 -I test-py-io.py pyio://3 Registering Python IO plugin... True python-check pyio://3 MyPyIO Opening pyio://3 [3] 14147 segmentation fault (core dumped) r2 -I test-py-io.py pyio://3 A little debugging:

it crashes when the code tries to access io->desc->plugin->listener, since io->desc->plugin pointer value is 0x4d2, which is the value returned by the open function in the pyio plugin.

How can i create my RIODesc in Python and return the correct value ? Should we fix the example maybe ?

Thanks

Now the plugin won't be opened anymore:

$ r2 -I test-py-io.py pyio://3
Registering Python IO plugin...
True
[r] Cannot open 'pyio://3'

so its related to the silly mess of python libraries :(

Now i cannot open the plugin anymore, commit reverted or not. what happened ?

radare commented 6 years ago

i dont know, i cant reproduce, python is crap. maybe someone else can help here, can you provide a way to reproduce? (a shellscript or so)

This Dockerfile reproduces the segfault:

FROM debian:stable

RUN apt-get update && apt-get install -y build-essential git wget \
        python3 python3-dev python pkg-config

RUN cd /root && git clone https://github.com/radare/radare2/ && \
        ./radare2/sys/install.sh

RUN r2pm init
RUN r2pm -i lang-python3

WORKDIR /root
RUN wget 'https://raw.githubusercontent.com/radare/radare2-bindings/master/libr/lang/p/test-py-io.py'

ENTRYPOINT r2 -I test-py-io.py pyio://33

output

Does the Dockerfile i provided have been helpful ?

Wenzel commented 6 years ago

maybe cc @XVilka, if you have some comment ?

Wenzel commented 6 years ago

I updated the Dockerfile using the official radare2 image:

FROM radare/radare2

USER root
RUN apt-get update && apt-get install -y build-essential git wget \
        python3 python3-dev python pkg-config

USER r2
RUN r2pm init
RUN r2pm -i lang-python3

RUN wget 'https://raw.githubusercontent.com/radare/radare2-bindings/master/libr/lang/p/test-py-io.py'

ENTRYPOINT r2 -I test-py-io.py pyio://33

Still segfaults :)
