From f3ca5ca82abe35d13210f8a8035926170bb87436 Mon Sep 17 00:00:00 2001 From: Dean Deng Date: Tue, 28 Apr 2020 08:32:20 -0700 Subject: Support pipes and sockets in VFS2 gofer fs. Named pipes and sockets can be represented in two ways in gofer fs: 1. As a file on the remote filesystem. In this case, all file operations are passed through 9p. 2. As a synthetic file that is internal to the sandbox. In this case, the dentry stores an endpoint or VFSPipe for sockets and pipes respectively, which replaces interactions with the remote fs through the gofer. In gofer.filesystem.MknodAt, we attempt to call mknod(2) through 9p, and if it fails, fall back to the synthetic version. Updates #1200.
