Confirmed that this is triggered by a combination of Yama assuming that i_uid is populated in file inodes, and overlayfs not populating this field. Have started an upstream conversation on whether it is possible to assume this is populated or not in the face of an inode with a permissions() op. This will allow us to determine which is at fault.
