2018-08-14Fix bind() on overlays.Nicolas Lacasse
InodeOperations.Bind now returns a Dirent which will be cached in the Dirent tree. When an overlay is in-use, Bind cannot return the Dirent created by the upper filesystem because the Dirent does not know about the overlay. Instead, overlayBind must create a new overlay-aware Inode and Dirent and return that. This is analagous to how Lookup and overlayLookup work.

2018-08-10fs: Allow overlays to revalidate files from the upper fs.Nicolas Lacasse
Previously, an overlay would panic if either the upper or lower fs required revalidation for a given Dirent. Now, we allow revalidation from the upper file, but not the lower. If a cached overlay inode does need revalidation (because the upper needs revalidation), then the entire overlay Inode will be discarded and a new overlay Inode will be built with a fresh copy of the upper file. As a side effect of this change, Revalidate must take an Inode instead of a Dirent, since an overlay needs to revalidate individual Inodes.

2018-08-10Enable checkpoint/restore in cases of UDS use.Brielle Broder
Previously, processes which used file-system Unix Domain Sockets could not be checkpoint-ed in runsc because the sockets were saved with their inode numbers which do not necessarily remain the same upon restore. Now, the sockets are also saved with their paths so that the new inodes can be determined for the sockets based on these paths after restoring. Tests for cases with UDS use are included. Test cleanup to come. PiperOrigin-RevId: 208268781 Change-Id: Ieaa5d5d9a64914ca105cae199fd8492710b1d7ec
