2020-05-29Update Go version build tagsMichael Pratt
None of the dependencies have changed in 1.15. It may be possible to simplify some of the wrappers in rawfile following 1.13, but that can come in a later change. PiperOrigin-RevId: 313863264

2020-05-29Move TCP to CLOSED from SYN-RCVD on RST.Mithun Iyer
RST handling is broken when the TCP state transitions from SYN-SENT to SYN-RCVD in case of simultaneous open. An incoming RST should trigger cleanup of the endpoint. RFC793, section 3.9, page 70. Fixes #2814 PiperOrigin-RevId: 313828777

2020-05-29Fix the APT repository structure.Adin Scannell
This change fixes the apt repository structure to avoid emiting warnings on Ubuntu 18.04 (and potentially other versions). This requires a slight refactor of the repository generation scripts, since we can no longer copy the same release files for different "suites". This should avoid the warning by setting the suite to the distribution: https://github.com/Debian/apt/blob/master/apt-pkg/metaindex.cc#L75 This change also moves over to the standardized Makefile entrypoint, which makes settings clearer and enables local testing.

2020-05-29Port inotify to vfs2, with support in tmpfs.Dean Deng
Support in other filesystem impls is still needed. Unlike in Linux and vfs1, we need to plumb inotify down to each filesystem implementation in order to keep track of links/inode structures properly. IN_EXCL_UNLINK still needs to be implemented, as well as a few inotify hooks that are not present in either vfs1 or vfs2. Those will be addressed in subsequent changes. Updates #1479. PiperOrigin-RevId: 313781995
2020-05-28Split VFS.MountAt into VFS.MountDisconnected and VFS.ConnectMountAt.Jamie Liu
This makes it straightforward to create bind mounts internally in VFS2: Given a bind mount root represented by vfs.VirtualDentry vd: - Create a new mount with VFS.NewDisconnectedMount(vd.Mount().Filesystem(), vd.Dentry()). - Connect the resulting mount in the appropriate namespace with VFS.ConnectMountAt(). Note that the resulting bind mount is non-recursive; recursive bind mounting requires explicitly duplicating all children of the original mount, which is best handled internally by VFS.

2020-05-27Correctly update link and ref counts in rmdir.Dean Deng
Inotify sends events when a watch target is reaches a link count of 0 (see include/linux/fsnotify.h:fsnotify_inoderemove). Currently, we do not account for both dir/ and dir/.. in unlink, causing syscalls/linux/inotify.cc:WatchTargetDeletionGeneratesEvent to fail because the expected inotify events are not generated. Furthermore, we should DecRef() once the inode reaches zero links; otherwise, we will leak a reference. PiperOrigin-RevId: 313502091
2020-05-27Remove linkEP from DeliverNetworkPacketSam Balana
The specified LinkEndpoint is not being used in a significant way. No behavior change, existing tests pass. This change is a breaking change. PiperOrigin-RevId: 313496602

2020-05-25Ensure docker group exists in the container.Adin Scannell
The --groups command will fail if the group is not defined in /etc/groups, even though it is specified by GID. By coincidence, the group happens to be there for many installations of Ubuntu 18.04 (which uses 999 for the Docker group), but it is strangely absent in others (which use 130). Fixes #2765

VFS2 is adding more functionality than VFS1. In order to test new functionality, it's required to skip some tests with VFS1. To skip tests, use: SKIP_IF(IsRunningWithVFS1()); The test will run in Linux and gVisor with VFS2 enabled. Updates #1035 PiperOrigin-RevId: 312698616

2020-05-20Implement gap tracking in the segment set.Reapor-Yurnero
This change was derived from a change by: Reapor-Yurnero <reapor.yurnero@gmail.com> And has been modified by: Adin Scannell <ascannell@google.com> (The original change author is preserved for the commit.) This change implements gap tracking in the segment set by adding additional information in each node, and using that information to speed up gap finding from a linear scan to a O(log(n)) walk of the tree. This gap tracking is optional, and will default to off except for segment instances that set gapTracking equal to 1 in their const lists. PiperOrigin-RevId: 312621607

These packages don't actually use go_stateify or go_marshal, but end up implicitly dependent on the respective packages due to our build rules. These unnecessary dependencies make them unusuable in certain contexts due to circular dependency. PiperOrigin-RevId: 312595738
