2019-06-11Add support to mount pod shared tmpfs mountsFabricio Voznika
Parse annotations containing 'gvisor.dev/spec/mount' that gives hints about how mounts are shared between containers inside a pod. This information can be used to better inform how to mount these volumes inside gVisor. For example, a volume that is shared between containers inside a pod can be bind mounted inside the sandbox, instead of being two independent mounts. For now, this information is used to allow the same tmpfs mounts to be shared between containers which wasn't possible before. PiperOrigin-RevId: 252704037

2019-03-18Add support for mount propagationFabricio Voznika
Properly handle propagation options for root and mounts. Now usage of mount options shared, rshared, and noexec cause error to start. shared/ rshared breaks sandbox=>host isolation. slave however can be supported because changes propagate from host to sandbox. Root FS setup moved inside the gofer. Apart from simplifying the code, it keeps all mounts inside the namespace. And they are torn down when the namespace is destroyed (DestroyFS is no longer needed). PiperOrigin-RevId: 239037661 Change-Id: I8b5ee4d50da33c042ea34fa68e56514ebe20e6e0
