Description Dmitry Butskoy 2009-11-23 11:17:53 UTC
Since the version 3.2.X, smbd server no more provides remote quota management. Neither using smbcquotas (from a remote machine) nor by the native windows  desktop.

The problem seems to be at smbd/nttrans.c:reply_ntcreate_and_X() function. It calls smbd/reply.c:srvstr_get_path(), which calls smbd/reply.c:check_path_syntax(), which does not allow FAKE_FILE_NAME_QUOTA_WIN32 and FAKE_FILE_NAME_QUOTA_UNIX, as such a name does not contain ":$DATA" at the end...

As result, srvstr_get_path() returns failure "wrong parameter", which is reported to the remote system, and remote system interpretes it as no quota on the server.

The work-around seems to be simple, but I'm not sure whether it is strongly correct.

The patch against 3.2.15

With this patch (a kludge? :) ) applied, both smbcquotas and native windows can change quota remotely.

According to the source code, the problem seems to be present in 3.3 and 3.4 as well.
