2020-06-01Add inotify events for extended attributes and splice.Dean Deng
Splice, setxattr and removexattr should generate events. Note that VFS2 already generates events for extended attributes. Updates #1479. PiperOrigin-RevId: 314244261
2020-06-01Fix VFS2 gofer open(O_CREAT) reference leak.Jamie Liu
gofer.filesystem.createAndOpenChildLocked() doesn't need to take a reference on the new dentry since vfs.FileDescription.Init() will do so. PiperOrigin-RevId: 314242127
2020-06-01Handle gofer blocking opens of host named pipes in VFS2.Jamie Liu
Using tee instead of read to detect when a O_RDONLY|O_NONBLOCK pipe FD has a writer circumvents the problem of what to do with the byte read from the pipe, avoiding much of the complexity of the fdpipe package. PiperOrigin-RevId: 314216146

2020-06-01Include runtime goroutines in panicsMichael Pratt
SetTraceback("all") does not include all goroutines in panics (you didn't think it was that simple, did you?). It includes all _user_ goroutines; those started by the runtime (such as GC workers) are excluded. Switch to "system" to additionally include runtime goroutines, which are useful to track down bugs in the runtime itself. PiperOrigin-RevId: 314204473

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
