Discussion of socket implementation

[Runji Wang]

• Is it possible to treat a socket as a file directly?
  sockfs: impl INode for Socket
• If we can, what should be added to the current VFS?
• If not, can we design a socket trait to isolate syscall and network stack?

• Is it possible to treat a socket as a file directly?
  • It let me think of Plan9 OS.
  • Hard, the syscalls needed to support have different semantics, but easy if we just throw then away.
• If we can, what should be added to the current VFS?
  • /dev/tcp/addr/port? (as in bash)
  • Use ioctl for specific operations other than writing and reading?
• If not, can we design a socket trait to isolate syscall and network stack?
  • Yes. I think we can delegate syscall to each type of socket struct.
