Python: Using r2pipe for analysing memory dump of an android process #143

Closed saneeha-amir closed 2 years ago

saneeha-amir commented 2 years ago

hello,

I want to disassemble a process dump obtained from an android device. The dump is obtained using volatility 'linux_procdump' command. The redare2 interface is working fine on the dump and I can see the disassembled instructions. But r2pipe script gives the following error:

"Warning: run r2 with -e bin.cache=true to fix relocations in disassembly"

The script i have written is as under:

import r2pipe r= r2pipe.open('./dump',flags=['-e']) r.cmd('aaa') print r.cmd('afl')

Kindly guide. Ill be really grateful

The -e flag requires an argument

the warning you see is not an error and it will happen on notmal r2 unless you do what it says

Many thanks for your response. Please guide what should i do as the screen is stuck with this warning.

Can you please correct the command i m using. r= r2pipe.open('./dump',flags=['-e'])

Ill be really grateful

dear all, I have figured out that 'e' represents all the configuration variables. I think i need to set the configuration variable of bin.cache to true. It is currently false. I should run r2pipe after resetting. Please guide which file contains the configuration settings of radare2 as i m unable to find the configuration file. Ill be grateful

Dear all,

I have finally been able to run r2pipe. It was a problem with python. I was using python2. r2pipe is working perfectly fine with python3.

Warning is there but output is obtained.

Sorry for the delay, ivebeen busy irl during the last 6 days.

the line should be:

r= r2pipe.open('./dump',flags=['-ebin.cache=true'])

trufae commented 2 years ago

uhm, in theory r2pipe should run fine in python2, but its better to get rid of it as its deprecated and unmaintained.

saneeha-amir commented 2 years ago

Many thanks for your reply. I have changed the command as you have suggested and the warning is gone.

I have again verified running with python2 , but it is not working on my system. Python3 is working fine.
