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

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

2020-02-20Initial 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.

2020-02-18Enable 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.

2020-02-18atomicbitops package cleanupsgVisor bot
- Redocument memory ordering from "no ordering" to "acquire-release". (No functional change: both LOCK WHATEVER on x86, and LDAXR/STLXR loops on ARM64, already have this property.) - Remove IncUnlessZeroInt32 and DecUnlessOneInt32, which were only faster than the equivalent loops using sync/atomic before the Go compiler inlined non-unsafe.Pointer atomics many releases ago.

2020-02-14Remove linux.EpollEvent.Fd.gVisor bot
glibc defines struct epoll_event in such a way that epoll_event.data.fd exists. However, the kernel's definition of struct epoll_event makes epoll_event.data an opaque uint64, so naming half of it "fd" just introduces confusion. Remove the Fd field, and make Data a [2]int32 to compensate. Also add required padding to linux.EpollEvent on ARM64. PiperOrigin-RevId: 295250424
