This patch brings various improvements to the shellcoding experience:
- There is no longer a hardcoded assembly sample that gets built
Although the default was pretty sane, it will be more convenient
to experiment, or build more complex shellcodes using a new
untracked filename as the main build target: code.asm
If code.asm is missing, then as before, it will be created from
shell64.asm (the old hard default).
The Makefile targets will compile code.* files.
- Hex string generation and bad char detection are improved
grep is used to highlight detected bad chars right in place.
This entire feature is now implemented directly in the Makefile
using a couple command lines, making shelltool deprecated.
- Builtin disassembly
Just run 'make disas' instead of manually invoking objdump. The
output is also filtered through grep for bad char detection.
- ELF executable is optional
Rather than linking an executable all the time, just run
'make elf' when you need it.
