Reverse cmd in rap
Closed this issue · 12 comments
We need a way for rap servers to run commands in r2 host. something like this:
r2 <----> rap://target
> CMD(x)
< CMD(y)
> CMD|REPLY(res-y)
< CMD|REPLY(res-x)
This will be useful when writing debug backends using rap://, so the io plugin can run r2 commands to change register values and stuff like that. we should slowly redesign this to support remote debuggers in a better way
I am interested in solving this? This is my idea right now, Basically When the host is Listening for Incoming Connections, I Should use (select() or new thread) for reading from stdin and pass that to existing functions right?? (tell me if this is the right path?)
@jarusified radare2 already has it's own API to talk via the network - see libr/include/r_socket.h for API and libr/socket/*.c for implementation.
@XVilka will use that. But is the overall understanding of the issue correct?
@jarusified there yes, just add the answering part.
you can test this by doing:
$ r2 rap://:9999
and then:
$ r2 rap://localhost:9999//bin/ls
the idea behind this issue is to review/cleanup/document the rap protocol
and add support for the server side to issue commands in the host one. This
will be easier to test/implement if done in python or nodejs, there are
already implementations of that protocol for them.
This is important because it will allow non-r2 rap servers to tell r2 which
commands to run to set flags, change register state, emulate step, etc.
Only the command packet makes sense to be bidirectional imho.

initial fix : radareorg/radare2-bindings#107
It's good to have this fix in python, but the proper fix should be in core, are you planning to do it too?
yes, i am planning to do the same.
cool!
