of my old assembly web server found here: https://github.com/igoforth/codesamples/blob/master/x86-64/getpostserver.s
The vision is to create an x86_64 web server that can handle GET (and someday POST) requests consistently.
Objectives:
- Lightweight
- Elegant
- Reliable
Features:
- A "security implementation" that checks the request path against a list of forbidden bytes to prevent file access beyond the cwd
- Parent/child process architecture that speeds up client request handling
The program does not use:
- libc
- IPv6
Constraints:
- Will GET content up to 2GiB-1
- Handle file names up to 255B, linux max-1
- Will not parse url encoding
Forbidden in paths:
- Spaces " " (0x20) (By nature of the program, this will just break things)
- More than one dot "." (0x2E)
- More than one forward slash "/" (0x2F)
- Bad ASCII bytes :*?%"<>| (0x5C 0x3A 0x2A 0x3F 0x22 0x3C 0x3E 0x7C)
Future ideas:
- Implement POST request handling
- Handle SIGINT to exit gracefully
- More verbose connection logging
- Ensure server will respond to fully-featured browsers
- Clean up code to ensure consistent style
