Add TCP Reverse Shell

[alichtman]

Make userspace calls from kernel space.

If we want to do that, first read this.

Implementation

• Take in IP address and Port to connect to in setup.py, or through $ /garden rev_tcp IP PORT

Still need to figure out how this will actually be called.

[alichtman]

Decided to go with the magic packet approach.

Kernel panic somewhere in the process after the rootkit detects a reverse shell request.

Good tutorials:

1. Execute usermode helper within a syscall
2. Magic Packets, almost exactly what I'm trying to do but a bit outdated
3. Kernel Workqueues 1
4. Kernel Workqueues 2

Or debug with vmss2core.
