| |
-stable review patch. If anyone has any objections, please let us know. ---------------------
From: Steve French <sfrench@us.ibm.com>
upstream commit: 076d8423a98659a92837b07aa494cb74bfefe77c
When a share was in DFS and the server was Unix/Linux, we were sending paths of the form \\server\share/dir/file rather than //server/share/dir/file
There was some discussion between me and jra over whether we should use /server/share/dir/file as MS sometimes says - but the documentation for this claims it should be doubleslash for this type of UNC-like path format and that works, so leaving it as doubleslash but converting the \ to / in the the //server/share portion.
This gets Samba to now correctly return STATUS_PATH_NOT_COVERED when it is supposed to (Windows already did since the direction of the slash was not an issue for them). Still need another minor change to fully enable DFS (need to finish some chages to SMBGetDFSRefer
