2012-02-16s3-smbd Remove unused code now we always have SPNEGO via gensecAndrew Bartlett1-36/+4
This was previously needed because SPNEGO was only available in the AD DC. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-01-05s3-auth Remove ntlmssp_wrap.h which is no longer requiredAndrew Bartlett1-1/+0
Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-01-05s3-auth use gensec directly rather than via auth_generic_stateAndrew Bartlett1-5/+5
This is possible because the s3 gensec modules are started as normal gensec modules, so we do not need a wrapper any more. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-01-05s3-auth Add TALLOC_CTX * to auth_generic_prepare()Andrew Bartlett1-1/+2
This makes the long term owner of this memory more clear. So far only the clear cases have been moved from NULL however. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2011-12-22s3-auth rename auth_ntlmssp_prepare() -> auth_generic_prepare()Andrew Bartlett1-1/+1
This function handles more than NTLMSSP now, at least when we are an AD DC and so changing the name may avoid some confusion in the future. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

2011-09-05s3:smb2_server: add basic support for SMB 2.1Stefan Metzmacher1-0/+1
This adds support for the 2 stage negprot, from SMB 1 to SMB 2.1. Support for this of for now and "max protocol = SMB2" still maps to "max protocol = SMB2_02" PROTOCOL_SMB2_02. In order to activate smb2.1, you need to use "max protocol = SMB2_10". metze Autobuild-User: Stefan Metzmacher <metze@samba.org> Autobuild-Date: Mon Sep 5 19:30:58 CEST 2011 on sn-devel-104

2011-08-31s3: Fix bug 8334, do not fork the echo handler for smb2Volker Lendecke1-1/+2
If a smb1 negprot negotiated smb2 we forked the echo responder. This will eventually lead to a panic from [2011/08/30 10:33:29.212578, 0, pid=3846917] smbd/smb2_server.c:243(smbd_smb2_request_create) Invalid SMB packet: first request: 0x0009 because from the echo responder we always read using the normal smb1 protocol handling routine. If that is a bit down the smb2 stream, we get a non-negprot packet and panic. BTW, the echo responder is not required for smb2 anyway, Microsoft confirmed that it probes the server liveness using TCP keepalives and not smb2 echo requests.

2011-08-03s3-auth use auth_generic_start to get full GENSEC in Samba3 session setupAndrew Bartlett1-1/+27
This tests if the auth_generic_start() hook is available on the auth context during the negprot, and if so it uses auth_generic_start() to hook to GENSEC to handle the full SPNEGO blob. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

2011-06-09s3-param Remove special case for global_myname(), rename to lp_netbios_name()Andrew Bartlett1-2/+2
There is no reason this can't be a normal constant string in the loadparm system, now that we have lp_set_cmdline() to handle overrides correctly. Andrew Bartlett
2011-06-09s3-talloc Change TALLOC_REALLOC_ARRAY() to talloc_realloc()Andrew Bartlett1-1/+1
Using the standard macro makes it easier to move code into common, as TALLOC_REALLOC_ARRAY isn't standard talloc. Andrew Bartlett
2011-05-20s3: Fork the echo handler only after SMB1 negprot is doneVolker Lendecke1-0/+5
This enables activating the echo responder also if SMB2 is enabled, albeit it will only be used for SMB1 at this moment. Autobuild-User: Volker Lendecke <vlendec@samba.org> Autobuild-Date: Fri May 20 15:06:03 CEST 2011 on sn-devel-104

2010-12-10s3-smbd Don't send SPNEGO principal (rfc4178 hint) by defaultAndrew Bartlett1-0/+3
This patch, based on the suggestion by Goldberg, Neil R. <ngoldber@mitre.org> turns off the sending of the principal in the negprot by default, matching Windows 2008 behaviour. This slowly works us back from this hack, which from an RFC perspective was never the right thing to do in the first place, but we traditionally follow windows behaviour. It also discourages client implmentations from relying on it, as if they do they are more open to man-in-the-middle attacks. Andrew Bartlett

2010-07-19Remove gen_negTokenInit() - change all callers to spnego_gen_negTokenInit().Jeremy Allison1-3/+3
We now have one function to do this in all calling code. More rationalization to follow. Jeremy.

into negprot_spnego() where it belongs (it's not an SPNEGO operation). Add a TALLOC_CTX for callers of negprot_spnego(). Closer to unifying all the gen_negTokenXXX calls. Jeremy.

Turn the freeing function into a destructor and attach it to the auth_context. Make all callers TALLOC_FREE() the auth_context instead of calling the free function. Signed-off-by: Andrew Bartlett <abartlet@samba.org>

2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke1-2/+2
When a samba server process dies hard, it has no chance to clean up its entries in locking.tdb, brlock.tdb, connections.tdb and sessionid.tdb. For locking.tdb and brlock.tdb Samba is robust by checking every time we read an entry from the database if the corresponding process still exists. If it does not exist anymore, the entry is deleted. This is not 100% failsafe though: On systems with a limited PID space there is a non-zero chance that between the smbd's death and the fresh access, the PID is recycled by another long-running process. This renders all files that had been locked by the killed smbd potentially unusable until the new process also dies. This patch is supposed to fix the problem the following way: Every process ID in every database is augmented by a random 64-bit number that is stored in a serverid.tdb. Whenever we need to check if a process still exists we know its PID and the 64-bit number. We look up the PID in serverid.tdb and compare the 64-bit number. If it's the same, the process still is a valid smbd holding the lock. If it is different, a new smbd has taken over. I believe this is safe against an smbd that has died hard and the PID has been taken over by a non-samba process. This process would not have registered itself with a fresh 64-bit number in serverid.tdb, so the old one still exists in serverid.tdb. We protect against this case by the parent smbd taking care of deregistering PIDs from serverid.tdb and the fact that serverid.tdb is CLEAR_IF_FIRST. CLEAR_IF_FIRST does not work in a cluster, so the automatic cleanup does not work when all smbds are restarted. For this, "net serverid wipe" has to be run before smbd starts up. As a convenience, "net serverid wipedbs" also cleans up sessionid.tdb and connections.tdb. While there, this also cleans up overloading connections.tdb with all the process entries just for messaging_send_all(). Volker
