2020-05-07Update privateunixsocket TODOs.Dean Deng
Synthetic sockets do not have the race condition issue in VFS2, and we will get rid of privateunixsocket as well. Fixes #1200. PiperOrigin-RevId: 310386474

2020-05-06Fix runsc syscall documentation generation.Adin Scannell
We can register any number of tables with any number of architectures, and need not limit the definitions to the architecture in question. This allows runsc to generate documentation for all architectures simultaneously. Similarly, this simplifies the VFSv2 patching process. PiperOrigin-RevId: 310224827

2020-04-27runsc: extend do network cleanupMichael Pratt
Previously we unconditionally failed to cleanup the networking files (hostname, resolve.conf, hosts), and failed to cleanup the netns, etc on partial setup failure. We can drop the iptables commands from cleanup, as the routes automatically go away when the device is deleted. Those commands were failing previously. Forward signals to the container, allowing it to exit normally when a signal is received, and then for runsc to run the cleanup. This doesn't cover cleanup when runsc is signalled before the container start, it covers the most common case. Fixes #2539 Fixes #2540
2020-04-27container: use sighandling packageMichael Pratt
Use the sighandling package for Container.ForwardSignals, for consistency with other signal forwarding. Fixes #2546

2020-04-25Add container tests passing with VFS2Zach Koopmans
Several tests are passing after getting TestAppExitStatus (run /bin/true) changes. Make versions that run via VFS2 so that we know what is and isn't working. In addition, fix bug in VFSFile ReadFull. For the TestExePath test in container_test.go, the case "unmasked" will return 0 bytes read with no EOF err, causing the ReadFull call to spin. PiperOrigin-RevId: 308428126

2020-04-24VFS2: Get HelloWorld image tests to pass with VFS2Zach Koopmans
This change includes: - Modifications to loader_test.go to get TestCreateMountNamespace to pass with VFS2. - Changes necessary to get TestHelloWorld in image tests to pass with VFS2. This means runsc can run the hello-world container with docker on VSF2. Note: Containers that use sockets will not run with these changes. See "//test/image/...". Any tests here with sockets currently fail (which is all of them but HelloWorld). PiperOrigin-RevId: 308363072

2020-04-24Move hostfs mount to Kernel struct.Dean Deng
This is needed to set up host fds passed through a Unix socket. Note that the host package depends on kernel, so we cannot set up the hostfs mount directly in Kernel.Init as we do for sockfs and pipefs. Also, adjust sockfs to make its setup look more like hostfs's and pipefs's. PiperOrigin-RevId: 308274053

2020-04-23Simplify Docker test infrastructure.Adin Scannell
This change adds a layer of abstraction around the internal Docker APIs, and eliminates all direct dependencies on Dockerfiles in the infrastructure. A subsequent change will automated the generation of local images (with efficient caching). Note that this change drops the use of bazel container rules, as that experiment does not seem to be viable. PiperOrigin-RevId: 308095430

This change renames the tools/images directory to tools/vm for clarity, and adds a functional vm_test. Sharding is also added to the same test, and some documentation added around key flags & variables to describe how they work. Subsequent changes will add vm_tests for other cases, such as the runtime tests. PiperOrigin-RevId: 307492245
