-Subject: [PATCH] ovl: don't copy up opaqueness
-
-When a copy up of a directory occurs which has the opaque xattr set, the
-xattr remains in the upper directory. The immediate behavior with overlayfs
-is that the upper directory is not treated as opaque, however after a
-remount the opaque flag is used and upper directory is treated as opaque.
-This causes files created in the lower layer to be hidden when using
-multiple lower directories.
-
-Fix by not copying up the opaque flag.
-
-To reproduce:
-
- ----8<---------8<---------8<---------8<---------8<---------8<----
-mkdir -p l/d/s u v w mnt
-mount -t overlay overlay -olowerdir=l,upperdir=u,workdir=w mnt
-rm -rf mnt/d/
-mkdir -p mnt/d/n
-umount mnt
-mount -t overlay overlay -olowerdir=u:l,upperdir=v,workdir=w mnt
-touch mnt/d/foo
-umount mnt
-mount -t overlay overlay -olowerdir=u:l,upperdir=v,workdir=w mnt
-ls mnt/d
- ----8<---------8<---------8<---------8<---------8<---------8<----
-
-output should be:  "foo  n"
