openssh unix dev - Sep 2009 - Cannot rename across bind mounts

Hello,

I am having problems with renaming a file if the source or destination path is
located on a bind mount.

For instance if in the root directory, I have the directories "Files1"
and "Files2" where one or both of the directories are created as the
result of a bind mount, then when trying to do

rename /Files1/a /Files2/b

it produces an error saying it "Couldn't rename file".

The ownership and permissions of files and directories have no bearing on this
problem. Renaming the files without going outside of the bind mount doesn't
cause problems, only when crossing the bind mount does the error occur.

Is this a bug, or is this an intended behavior for some security reason?

Thanks,

Are the two directories bound to different places within the same
filesystem?

Yes.

BTW: I'm currently using 5.2p1 from Gentoo portage, patched with
sftpfilecontrol-v1.3
