Non-empty directories can be marked delete on close in CIFS, but not actually deleted
We're affected by an issue where a client is allowed to set the delete on close flag on a directory, but the server will fail to delete the directory without informing the client because it is non-empty at the time of close.
The characteristic message from smbsrv is:
WARNING: File <name> could not be removed, rc=17.
"This DOES appear to be the issue where we allow a
non-empty directory to be marked for deletion on
close, when indeed the delete will fail due to the
directory not being empty."
http://www.nexenta.org/boards/1/topics/1035 has packet traces.
Also as Bugster 6984617 Setting Delete on close on non-empty directory returns success, but directory will not be deleted.
