2020-02-25Fix DATA RACE in fs.MayDelete.Adin Scannell
MayDelete must lock the directory also, otherwise concurrent renames may race. Note that this also changes the methods to be aligned with the actual Remove and RemoveDirectory methods to minimize confusion when reading the code. (It was hard to see that resolution was correct.)

2020-02-25Port most syscalls to VFS2.Jamie Liu
pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2. mount and umount2 aren't ported out of temporary laziness. access and faccessat need additional FSImpl methods to implement properly, but are stubbed to prevent googletest from CHECK-failing. Other syscalls require additional plumbing. Updates #1623 PiperOrigin-RevId: 297188448

Fixes #1049 PiperOrigin-RevId: 297175164
2020-02-25Fix mount refcount issue.Adin Scannell
Each mount is holds a reference on a root Dirent, but the mount itself may live beyond it's own reference. This means that a call to Root() can come after the associated reference has been dropped. Instead of introducing a separate layer of references for mount objects, we simply change the Root() method to use TryIncRef() and allow it to return nil if the mount is already gone. This requires updating a small number of callers and minimizes the change (since VFSv2 will replace this code shortly). PiperOrigin-RevId: 297174230
2020-02-25Deflake TestCurrentConnectedIncrement.Bhasker Hariharan
TestCurrentConnectedIncrement fails consistently under gotsan due to the sleep to check metrics is exactly the same as the TIME-WAIT duration. Under gotsan things can be slow enough that the increment test is done before the protocol goroutine is run after the TIME-WAIT timer expires and does its cleanup. Increasing the sleep from 1s to 1.2s makes the test pass consistently. PiperOrigin-RevId: 297160181
2020-02-25Add log during process wait in testsFabricio Voznika
TestMultiContainerKillAll timed out under --race. Without logging, we cannot tell if the process list is still increasing, but slowly, or is stuck. PiperOrigin-RevId: 297158834

2020-02-24Add support for tearing down protocol dispatchers and TIME_WAIT endpoints.Ian Gudger
Protocol dispatchers were previously leaked. Bypassing TIME_WAIT is required to test this change. Also fix a race when a socket in SYN-RCVD is closed. This is also required to test this change. PiperOrigin-RevId: 296922548

2020-02-21Fix master installer.Zach Koopmans
Sometimes, when we start a new instance, the file lock on "apt" is locked. Add a loop to the master installer. In addition, the "apt-get install" fails to register runsc in docker, so run the appropriate scripts to get that to happen. Also, add some helpful log messages. PiperOrigin-RevId: 296497357

2020-02-20Initial network namespace support.gVisor bot
TCP/IP will work with netstack networking. hostinet doesn't work, and sockets will have the same behavior as it is now. Before the userspace is able to create device, the default loopback device can be used to test. /proc/net and /sys/net will still be connected to the root network stack; this is the same behavior now.

2020-02-19Handle situations where go-marshal generates an empty test file.gVisor bot
This can happen due to conditional compilation, where a subset of the source files contain no marshallable types. go-marshal is still required to write an output file in these cases, since bazel defines the output package before calling go-marshal. PiperOrigin-RevId: 296074321

2020-02-18Enable IPV6_RECVTCLASS socket option for datagram socketsgVisor bot
Added the ability to get/set the IP_RECVTCLASS socket option on UDP endpoints. If enabled, traffic class from the incoming Network Header passed as ancillary data in the ControlMessages. Adding Get/SetSockOptBool to decrease the overhead of getting/setting simple options. (This was absorbed in a CL that will be landing before this one). Test: * Added unit test to udp_test.go that tests getting/setting as well as verifying that we receive expected TOS from incoming packet. * Added a syscall test for verifying getting/setting * Removed test skip for existing syscall test to enable end to end test.
