For example, if the system rootfs is on overlayfs due to composefs, or to make it volatile (via tmpfs), then you cannot currently store a lowerdir on the rootfs, because the inner overlayfs will eat all the whiteouts and overlay xattrs. This means you can't e.g. store on the rootfs a prepared container image for use with overlayfs. This adds support for nesting of overlayfs mounts by escaping the problematic features and unescaping them when exposing to the overlayfs user. - Add new mount options for appending lowerdirs * tag 'ovl-update-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs: ovl: add support for appending lowerdirs one by one ovl: refactor layer parsing helpers ovl: store and show the user provided lowerdir mount option ovl: remove unused code in lowerdir param parsing ovl: Add documentation on nesting of overlayfs mounts ovl: Add an alternative type of whiteout ovl: Support escaped overlay.* xattrs ovl: Add OVL_XATTR_TRUSTED/USER_PREFIX_LEN macros ovl: Move xattr support to new xattrs.c file ovl: do not encode lower fh with upper sb_writers held ovl: do not open/llseek lower file with upper sb_writers held ovl: reorder ovl_want_write() after ovl_inode_lock() ovl: split ovl_want_write() into two helpers ovl: add helper ovl_file_modified() ovl: protect copying of realinode attributes to ovl inode ovl: punt write aio completion to workqueue ovl: propagate IOCB_APPEND flag on writes to realfile ovl: use simpler function to convert iocb to rw flags |
