Add basic RISCV64 shellcraft support #2322

Closed peace-maker closed 6 months ago

peace-maker commented 9 months ago

Add the minimum shellcraft templates to be able to use the generated linux syscall templates under RISCV64.

The mov template isn't 100% null-byte and newline free for all inputs yet. Larger values are just emitted using the li pseudo-instruction by the assembler which might contain null-bytes. The ecall instruction to trigger syscalls contains null-bytes and we'd need some encoder to get around that.

This worked for me for a while so I'll merge and gather feedback when other start using it.
