Daniel Verkamp 11322f007d tree-wide: use LFS variants of libc functions 
Use the off64_t versions of libc file functions.

There is no Rust libc crate equivalent of the C _FILE_OFFSET_BITS and
related defines, so we have to use the Linux-specific *64 variants
explicitly.

This extends the size of file offsets to 64 bits instead of 32 on
platforms with 32-bit userspace.

(It also fixes the recently introduced check for non-LFS functions in
ChromeOS - see b/201531268 for details.)

p9 - Server implementation of the 9p file system protocol

This directory contains the protocol definition and a server implementation of the 9p file system protocol.

  • wire_format_derive - A procedural macro that derives the serialization and de-serialization implementation for a struct into the 9p wire format.
  • src/protocol - Defines all the messages used in the 9p protocol. Also implements serialization and de-serialization for some base types (integers, strings, vectors) that form the foundation of all 9p messages. Wire format implementations for all other messages are derived using the wire_format_derive macro.
  • src/server.rs - Implements a full 9p server, carrying out file system requests on behalf of clients.
