Particularly I want to make the use of various parameters that end up
calling smbrun() safe.
So far as I know ALL of those parameters are implemented in smbd only
(as they are SMB-specific) and, specifically, 'print command' and the
open/close command parameters call string_sub() directly with values
that are too dynamic to ever store in a TDB.
For an immediate solution I guess the best thing to do is to include a
function called, say, safe_quote() that takes a string and a buffer and
copies to the buffer a shell-quoted version of the given string, then
update 'print command' and Andy Bakun's open/close command patch to
safe_quote() the filename passed by the client prior to calling
For the long term the whole % token system will have to be modified as
Luke suggests, though %f will probably never end up in a TDB.
