2018-08-27fs: Fix remote-revalidate cache policy.Nicolas Lacasse
When revalidating a Dirent, if the inode id is the same, then we don't need to throw away the entire Dirent. We can just update the unstable attributes in place. If the inode id has changed, then the remote file has been deleted or moved, and we have no choice but to throw away the dirent we have a look up another. In this case, we may still end up losing a mounted dirent that is a child of the revalidated dirent. However, that seems appropriate here because the entire mount point has been pulled out from underneath us. Because gVisor's overlay is at the Inode level rather than the Dirent level, we must pass the parent Inode and name along with the Inode that is being revalidated.

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
