2020-05-01Port netstack, hostinet, and netlink sockets to VFS2.Dean Deng
All three follow the same pattern: 1. Refactor VFS1 sockets into socketOpsCommon, so that most of the methods can be shared with VFS2. 2. Create a FileDescriptionImpl with the corresponding socket operations, rewriting the few that cannot be shared with VFS1. 3. Set up a VFS2 socket provider that creates a socket by setting up a dentry in the global Kernel.socketMount and connecting it with a new FileDescription. This mostly completes the work for porting sockets to VFS2, and many syscall tests can be enabled as a result. There are several networking-related syscall tests that are still not passing: 1. net gofer tests 2. socketpair gofer tests 2. sendfile tests (splice is not implemented in VFS2 yet) Updates #1478, #1484, #1485 PiperOrigin-RevId: 309457331

2020-04-30Make tcp_close_wait_ack_test more accurateZeling Feng
Previously the test used an out-dated window size which is advertised during the handshake to generate testing packets, but the window size has changed since the handshake; currently it is using the most recent one which is advertised in DUT's ACK to our FIN packet to generate the testing outside-the-window packets.

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

2020-04-28Don'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
