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

2020-04-24Refactor syscall.Fstat calls in hostfs.Dean Deng
Just call syscall.Fstat directly each time mode/file owner are needed. This feels more natural than using i.getPermissions(). PiperOrigin-RevId: 308257405

2020-04-23Remove View.First() and View.RemoveFirst()Kevin Krakauer
These methods let users eaily break the VectorisedView abstraction, and allowed netstack to slip into pseudo-enforcement of the "all headers are in the first View" invariant. Removing them and replacing with PullUp(n) breaks this reliance and will make it easier to add iptables support and rework network buffer management. The new View.PullUp(n) method is low cost in the common case, when when all the headers fit in the first View. PiperOrigin-RevId: 308163542

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
