2011-06-21s3-build: Provide a run-time shim to work around duplicate symbolsAndrew Bartlett1-2/+2
The become_root() and similar 'smbd' functions that are used widely in Samba libraries had 'dummy' copies in dummysmbd.c and dummyroot.c. These have been replaced by a runtime plugin mechanim, which ensures that standlone binaries still do nothing, while in smbd the correct function is used. This avoids having these as duplicate symbols in the smbd binary, which can cause unpredictable behaviour. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-06-09lib/util Bring procid_str() into lib/util as server_id_string()Andrew Bartlett1-5/+5
This is needed for OpenChange, which prints Samba struct server_id values in debug messages. Andrew Bartlett
2011-06-09s3-talloc Change TALLOC_ARRAY() to talloc_array()Andrew Bartlett1-1/+1
Using the standard macro makes it easier to move code into common, as TALLOC_ARRAY isn't standard talloc.
2011-05-31s3-globals Remove smbd_event_context() (use server_event_context())Andrew Bartlett1-1/+1
This has been a wrapper around server_event_context() for some time now, and removing this from dummmysmbd.c assists with library dependencies. Andrew Bartlett

We should not grant levelII oplocks on a file with existing byte range locks.

2010-10-08s3: Hang the isilon kernel oplocks off the NULL contextVolker Lendecke1-1/+2
All I see is a fd_event that does not need a special destructor. Tim, Steven, I've added the #error as well for you to remove after review. Thanks, Volker Autobuild-User: Volker Lendecke <vlendec@samba.org> Autobuild-Date: Fri Oct 8 20:48:11 UTC 2010 on sn-devel-104
2010-10-08s3: Hang the irix kernel oplocks off the NULL ctxVolker Lendecke1-1/+1
Just a fd_event to be cleaned up. The pipe is closed implicitly.
2010-10-08s3: Hang the linux kernel oplocks off the NULL ctxVolker Lendecke1-1/+1
The destructor that is called removes the signal handler. But at process exit the signal handling is lost anyway.

2010-04-24Implement oplocks within SMB2. Plumb into the existing SMB1 oplock system.Jeremy Allison1-3/+3
Seems to work but needs more tests (to be added). Jeremy.
2010-04-12Move to using 64-bit mid values in our internal open file database.Jeremy Allison1-30/+30
This will allow us to share logic much easier between SMB1 and SMB2 servers. Jeremy
2010-04-09Plumb SMB2 stubs into all the places we defer SMB1 operations.Jeremy Allison1-12/+12
Rename functions to be internally consistent. Next step is to cope queueing single (non-compounded) SMB2 requests to put some code inside the stubs. Jeremy.

2009-11-03s3: Remove debug_ctx()Volker Lendecke1-5/+5
smbd just crashed on me: In a debug message I called a routine preparing a string that itself used debug_ctx. The outer routine also used it after the inner routine had returned. It was still referencing the talloc context that the outer debug_ctx() had given us, which the inner DEBUG had already freed.

2009-04-12We have to deny a level 2 oplock if kernel oplocks are enabledVolker Lendecke1-0/+6
The second r/o opener of a file is supposed to get a level2 oplock. The first opener due to the protection in process_oplock_break_message() has been forced to break to no oplock. The second opener according to locking.tdb gets a level2 oplock. Further down in open_file_ntcreate we try to set this level2 oplock in the kernel, and the non-clustered Linux kernel disallows this. The rules for the kernel leases are a bit baroque, but the attempt to do the SETLEASE correctly fails and we end up with no oplock for any client. In the clustered case however the linux kernel on the second opening node has not seen the open fd of the first node, it is only the cluster fs that has this information. If the cluster fs does not have the very same notion of leases as the local kernel has, we can end up with a WRLCK style kernel lease for the second opener where locking.tdb only indicates a level2 oplock. Getting a kernel oplock break signal with just a level2 oplock in locking.tdb is something smbd is not prepared for. For example after sending out the break in response to the kernel signal we set a timeout, waiting for a reply. More work needs to be done to make level2 kernel oplocks real for us. This patch addresses a real problem we have right now without them.

2009-03-23s3:smbd: use new simplified snb_signing code in the serverStefan Metzmacher1-24/+3
We keep the seqnum/mid mapping in the smb_request structure. This also moves one global variable into the smbd_server_connection struct. metze
2009-02-19s3: Add extid to the dev/inode pairTim Prouty1-14/+14
This extends the file_id struct to add an additional generic uint64_t field: extid. For backwards compatibility with dev/inodes stored in xattr_tdbs and acl_tdbs, the ext id is ignored for these databases. This patch should cause no functional change on systems that don't use SMB_VFS_FILE_ID_CREATE to set the extid. Existing code that uses the smb_share_mode library will need to be updated to be compatibile with the new extid.
2009-02-09s3 OneFS: Add kernel oplocks implementationTim Prouty1-0/+7
A few functions in oplocks_onefs.c need to be accessed from the onefs vfs module. It would be ideal if oplocks were implemented at the vfs layer, but since they aren't yet, a new header is added to source3/include to make these functions available to the onefs vfs module. oplocks_onefs.o doesn't need to be linked into the onefs vfs module explicitly, since it is already linked into smbd by default.
