commit 32861b926f1beef009d475b5c903a6b703f5bc1e
Author: Jeremy Allison <jra at samba.org>
Date: Fri Dec 18 14:28:22 2009 -0800
Actually explain the twisty paths of tortured logic behind
reply_doserror(), reply_nterror(), and reply_nterror(NT_STATUS_DOS()).
Fix the call in rely_openerror() to actually force a DOS error
for "too many open files".
Jeremy.
commit 0dd8c8a6ffed20be89ff1c407ea1d2876bd30792

reply_doserror() doesn't force DOS errors on the wire.
Start migrating uses of reply_doserror() to reply_nterror() with the
correct mapping. Eventually we'll get to the point where we can
change reply_doserror() to force a DOS error code on the wire,
and can change calls to reply_nterror(req, NT_STATUS_DOS()) - which *does*
force DOS errors on the wire - to reply_doserror(). Which might
actually make the server code look like it's making sense.
Jeremy.

/****************************************************************************
Create an error packet. Normally called using the ERROR() macro.
- Setting eclass and ecode only and status to NT_STATUS_OK forces DOS errors.
- Setting status only and eclass and ecode to zero forces NT errors.
- If the override errors are set they take precedence over any passed in values.
+
+ Setting eclass and ecode to zero and status to a valid NT error will
+ reply with an NT error if the client supports CAP_STATUS32, otherwise
+ it maps to and returns a DOS error if the client doesn't support CAP_STATUS32.
+ This is the normal mode of calling this function via reply_nterror(req, status).
+
+ Setting eclass and ecode to non-zero and status to NT_STATUS_OK (0) will map
+ from a DOS error to an NT error and reply with an NT error if the client
+ supports CAP_STATUS32, otherwise it replies with the given DOS error.
+ This is the path taken by calling reply_doserror(req, eclass, ecode).
+
+ Setting both eclass, ecode and status to non-zero values allows a non-default
+ mapping from NT error codes to DOS error codes, and will return one or the
+ other depending on the client supporting CAP_STATUS32 or not. This is the
+ path taken by calling reply_botherror(req, eclass, ecode, status);
+
+ Setting status to NT_STATUS_DOS(eclass, ecode) forces DOS errors even if the
+ client supports CAP_STATUS32. This is the path taken to force a DOS error
+ reply by calling reply_nterror(req, NT_STATUS_DOS(eclass, ecode)).
+ This is *very* unintuitive and the code should be changed so all
+ current callers of reply_doserror() which don't care if they return NTSTATUS
+ or DOS errors are changed to call reply_nterror() instead.
+ reply_doserror() should then be changed to return DOS errors only and
+ replace all current callers of reply_nterror(req, NT_STATUS_DOS(eclass, ecode)).
+ I'll update this comment once the conversion is done. JRA.
+
+ Setting status only and eclass to -1 forces NT errors even if the client
+ doesn't support CAP_STATUS32. This mode is currently never used in the
+ server.
