2013-10-16smbd: Decouple grant_fsp_oplock_type from oplock validationVolker Lendecke1-27/+26
This makes grant_fsp_oplock_type independent from the values computed in validate_oplock_types. It *might* make oplock calculation a bit slower for heavily shared files, as we are walking the share mode array twice. But we are doing so much stuff in open that I doubt the difference is measurable. It clears up the code for me however, and I think that's worth it.

2013-10-16smbd: Reduce the complexity of open_file_ntcreateVolker Lendecke1-24/+40
This removes two variables in open_file_ntcreate based on the observation that for exclusive and batch oplocks there can only be one entry. So in these cases we don't need to keep pointers from find_oplock_types to delay_for_oplocks. We can just reference the only share mode entry around.

https://bugzilla.samba.org/show_bug.cgi?id=10208 Authentication error in smb2 session reauth invalidates the session. In this case the session must in contrast to successful session setup requests be torn down and live no longer than the request.

2013-10-15smbd: Put "have_read_oplocks" into brlock.tdbVolker Lendecke2-10/+48
This implements an idea by metze: Right now Samba does not grant level2 oplocks where it should: After an initial no-oplock open that has been written to, we don't have the FAKE_LEVEL2_OPLOCK entry in locking.tdb around anymore, this downgraded to NO_OPLOCK. Windows in this case will grant level2 if being asked, we don't. Part of the reason for this is that we don't have a proper mechanism to communicate the fact that level2 needs to be broken to other smbds. Metze's insight was that we have to look into brlock.tdb for every write anyway, so this might be the right place to store this information. My first reaction was that this is really hackish, but on further thought this is not. oplocks depend on brlocks anyway, and we have the proper mechanisms in place for brlocks. The format for this change is to add one byte to the end of the brlock.tdb record with value 1 if we have level2 oplocks around. Thus this patch effectively reverts 8f41142 which I discovered while writing this change. We now legally have unaligned records. We can certainly talk about the format, but I'm not yet convinced we need an idl for this yet. This is a potentially very hot code path, and ndr marshalling has a cost.

2013-10-15s3-winbindd: Remove undocumented winbindd:socket dir parameterAndrew Bartlett5-9/+5
This uses the documeted "winbindd socket directory" parameter instead. This came about due to the merge of the two smb.conf tables in s3 and s4 for the Samba 4.0 release. The s4 code used a real parameter, which caused this to be documented, whereas no automatic procedure existed to notice the parametric option and the need to document that. The fact that this was not used consistently in both codebases is one of the many areas of technical debt we still need to pay off here.

2013-10-14param: disable print notify backchannel by defaultDavid Disseldorp4-7/+7
In handling RemoteFindFirstPrinterChangeNotifyEx requests, the spoolss server can establish a "backchannel" connection to the print client, as a mechanism for sending print notifications. This behaviour is governed by the "print notify backchannel" smb.conf parameter. This change sets "print notify backchannel" to "no" by default, which sees Samba respond to RemoteFindFirstPrinterChangeNotifyEx requests with WERR_SERVER_UNAVAILABLE. In recieving such a response, print clients can fall back to polling for print queue changes.
