2018-05-15sentry: Replaces saving of inet.Stack with retrieval via context.Kevin Krakauer
Previously, inet.Stack was referenced in 2 structs in sentry/socket that can be saved/restored. If an app is saved and restored on another machine, it may try to use the old stack, which will have been replaced by a new stack on the new machine.

2018-05-15Refactor the Sandbox package into Sandbox + Container.Nicolas Lacasse
This is a necessary prerequisite for supporting multiple containers in a single sandbox. All the commands (in cmd package) now call operations on Containers (container package). When a Container first starts, it will create a Sandbox with the same ID. The Sandbox class is now simpler, as it only knows how to create boot/gofer processes, and how to forward commands into the running boot process. There are TODOs sprinkled around for additional support for multiple containers. Most notably, we need to detect when a container is intended to run in an existing sandbox (by reading the metadata), and then have some way to signal to the sandbox to start a new container. Other urpc calls into the sandbox need to pass the container ID, so the sandbox can run the operation on the given container. These are only half-plummed through right now.

2018-05-10Skip atime and mtime update when file is backed by host FDFabricio Voznika
When file is backed by host FD, atime and mtime for the host file and the cached attributes in the Sentry must be close together. In this case, the call to update atime and mtime can be skipped. This is important when host filesystem is using overlay because updating atime and mtime explicitly forces a copy up for every file that is touched.

2018-05-09Return better errors from Docker when runsc fails to start.Nicolas Lacasse
Two changes in this CL: First, make the "boot" process sleep when it encounters an error to give the controller time to send the error back to the "start" process. Otherwise the "boot" process exits immediately and the control connection errors with EOF. Secondly, open the log file with O_APPEND, not O_TRUNC. Docker uses the same log file for all runtime commands, and setting O_TRUNC causes them to get destroyed. Furthermore, containerd parses these log files in the event of an error, and it does not like the file being truncated out from underneath it. Now, when trying to run a binary that does not exist in the image, the error message is more reasonable: $ docker run alpine /not/found docker: Error response from daemon: OCI runtime start failed: /usr/local/google/docker/runtimes/runscd did not terminate sucessfully: error starting sandbox: error starting application [/not/found]: failed to create init process: no such file or directory Fixes #32 PiperOrigin-RevId: 196027084 Change-Id: Iabc24c0bdd8fc327237acc051a1655515f445e68
