2019-06-19Add MountNamespace to task.Nicolas Lacasse
This allows tasks to have distinct mount namespace, instead of all sharing the kernel's root mount namespace. Currently, the only way for a task to get a different mount namespace than the kernel's root is by explicitly setting a different MountNamespace in CreateProcessArgs, and nothing does this (yet). In a follow-up CL, we will set CreateProcessArgs.MountNamespace when creating a new container inside runsc. Note that "MountNamespace" is a poor term for this thing. It's more like a distinct VFS tree. When we get around to adding real mount namespaces, this will need a better naem. PiperOrigin-RevId: 254009310

2019-05-23Initial support for bind mountsFabricio Voznika
Separate MountSource from Mount. This is needed to allow mounts to be shared by multiple containers within the same pod. PiperOrigin-RevId: 249617810 Change-Id: Id2944feb7e4194951f355cbe6d4944ae3c02e468

2018-09-07runsc: Support multi-container exec.Nicolas Lacasse
We must use a context.Context with a Root Dirent that corresponds to the container's chroot. Previously we were using the root context, which does not have a chroot. Getting the correct context required refactoring some of the path-lookup code. We can't lookup the path without a context.Context, which requires kernel.CreateProcArgs, which we only get inside control.Execute. So we have to do the path lookup much later than we previously were. PiperOrigin-RevId: 212064734 Change-Id: I84a5cfadacb21fd9c3ab9c393f7e308a40b9b537

2018-05-03Don't prematurely remove MountSource from parent's children.Christopher Koch
Otherwise, mounts that fail to be unmounted (EBUSY) will be removed from the children list anyway. At this point, this just affects /proc/pid/mounts and /proc/pid/mountinfo. PiperOrigin-RevId: 195267588 Change-Id: I79114483d73b90f9a7d764a7d513b5b2f251182e
