Maciek Swiech 0dc385a1f8 crosvm: p9: add support for lock() and getlock() to p9 
our current p9 server implementation does not support
fiile locks
(https://www.gnu.org/software/libc/manual/html_node/File-Locks.html).

NOTE: this implementation mirrors the QEMU approach, which defers
locking semantics to the client VFS. This means we do not provide
any guarantees about locks between client/server, nor between
multiple potential clients.

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.
