I think this needs some clarification. I'm not a samba/cifs developer but I would be in the "implementor" category. Can u give some examples of the backslash occuring in an ambiguous place? I'm assuming ur talking about the situation where some obnoxious user puts a backslash in a file name or directory name. Like /home/userluser/eLItE\haXor/ which creates a parsing ambiguity. A windows user would access that as \\server\share\userluser\eLItE\haXor\ which would be a problem. U wrote two backslashes in the text but put one in the example path. Did u mean to escape the backslash for the benefit of ur/our email client? If ur talking about when to interpret a backslash as a path seperator or as a literal then I think escaping the backslash with a second backslash would be the way to go. So my example would be required to be \\server\share\userluser\eLItE\\haXor\ or //server/share/userluser/eLItE\\haXor/. Am I reading ur question right and does my example make sense?

Subject: [linux-cifs-client] POSIX pathnames and the '\' character.
Currently the Samba server parsing code
treats '\\' as a directory separator even
when posix pathnames is set to true.
This means currently that we're not 100%
POSIX as '\\' is valid in a POSIX pathname,
the only banned characters are '/' and '\0'.
How much of a problem is this ? And how
much effort (if any) should I put into
fixing this ?
This includes all currently released
servers up to 3.0.24 that support the
POSIX pathnames extension.
The issue becomes a problem with DFS
pathnames, which are defined are :
'\\' is mandatory as a separator in the
first 2 path components. Do we want to
enforce a DFS name as :
or as :
or can we live with '\\' always being
a directory separator ?
