2020-04-29iptables: don't pollute logsKevin Krakauer
The netfilter package uses logs to make debugging the (de)serialization of structs easier. This generates a lot of (usually irrelevant) logs. Logging is now hidden behind a debug flag. PiperOrigin-RevId: 309087115

2020-04-28Fix Unix socket permissions.Dean Deng
Enforce write permission checks in BoundEndpointAt, which corresponds to the permission checks in Linux (net/unix/af_unix.c:unix_find_other). Also, create bound socket files with the correct permissions in VFS2. Fixes #2324. PiperOrigin-RevId: 308949084

2020-04-28Don't unlink named pipes in pipe test.Jamie Liu
TempPath's destructor runs at the end of the named pipe creation functions, deleting the named pipe. If the named pipe is backed by a "non-virtual" filesystem (!fs.Inode.IsVirtual()), this causes the following save attempt to fail because there are FDs holding the deleted named pipe open.

2020-04-28Support pipes and sockets in VFS2 gofer fs.Dean Deng
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. PiperOrigin-RevId: 308828161

2020-04-27Import host sockets.Dean Deng
The FileDescription implementation for hostfs sockets uses the standard Unix socket implementation (unix.SocketVFS2), but is also tied to a hostfs dentry. Updates #1672, #1476 PiperOrigin-RevId: 308716426

2020-04-27Reduce flakiness in tcp_test.Bhasker Hariharan
Poll for metric updates as immediately trying to read them can sometimes be flaky if due to goroutine scheduling the check happens before the sender has got a chance to update the corresponding sent metric. PiperOrigin-RevId: 308712817

2020-04-27runsc: extend do network cleanupMichael Pratt
Previously we unconditionally failed to cleanup the networking files (hostname, resolve.conf, hosts), and failed to cleanup the netns, etc on partial setup failure. We can drop the iptables commands from cleanup, as the routes automatically go away when the device is deleted. Those commands were failing previously. Forward signals to the container, allowing it to exit normally when a signal is received, and then for runsc to run the cleanup. This doesn't cover cleanup when runsc is signalled before the container start, it covers the most common case. Fixes #2539 Fixes #2540

2020-04-25Add container tests passing with VFS2Zach Koopmans
Several tests are passing after getting TestAppExitStatus (run /bin/true) changes. Make versions that run via VFS2 so that we know what is and isn't working. In addition, fix bug in VFSFile ReadFull. For the TestExePath test in container_test.go, the case "unmasked" will return 0 bytes read with no EOF err, causing the ReadFull call to spin. PiperOrigin-RevId: 308428126
