/proc emulation about tanner

[rnehra01]

@afeena I think current LFI emulator emulates /proc, and it can be made more effective using docker as implemented in CMD emulator (#144)

[afeena]

@rnehra01 I like docker, but I worried a bit about performance. Do you make tests with loading lots of containers simultaneously? Or maybe we should use one container for all attackers?

Using the script https://pastebin.com/QLsu8MRy, I got this result https://pastebin.com/5K2vSSh0. So, I guess docker is efficient.

[afeena]

Well done :) But I meant the resources of the host machine, we should remember about that, good reading https://docs.docker.com/engine/admin/resource_constraints/#limit-a-containers-access-to-memory

[rnehra01]

Okay, actually my initial doubt was that why this issue still open, although we have some sort of /proc emulation already.
So if you think docker can be inefficient, we can think of something else.

[rnehra01]

As you suggested, we can do one thing, we can provide an option to host/user, to use 1 for all attackers or one for each attacker in the config, so that user can do it as per available resources.

@rnehra01 I like the idea to make it manageable via config :)

[rnehra01]

I think we forgot one thing that in LFI, files are meant for reading purpose only, so we can use a single container.

@afeena I guess we can close this?
