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.
2010-04-07Start to plumb smb2 into the oplock system. Calls dummy functions for now.Jeremy Allison1-46/+41

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.
2009-07-20s3: Change fsp->fsp_name to be an smb_filename struct!Tim Prouty1-10/+14
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.
2009-02-09s3 oplocks: Add capabilites flags field to the kernel_oplocks structTim Prouty1-2/+28
Here is a short description for each of the new capability flags: KOPLOCKS_LEVEL2_SUPPORTED: Level 2 oplocks are supported natively in the kernel. KOPLOCKS_DEFERRED_OPEN_NOTIFICATION: The kernel notifies deferred openers when they can retry the open. KOPLOCKS_TIMEOUT_NOTIFICATION: The kernel notifies smbds when an oplock break times out. KOPLOCKS_OPLOCK_BROKEN_NOTIFICATION: The kernel notifies smbds when an oplock is broken.
2009-02-09s3 oplocks: Make the level2 oplock contention API more granularTim Prouty1-2/+23
This replaces release_level2_oplocks_on_change with contend_level2_oplock_begin/end in order to contend level2 oplocks throughout an operation rather than just at the begining. This is necessary for some kernel oplock implementations, and also lays the groundwork for better correctness in Samba's standard level2 oplock handling. The next step for non-kernel oplocks is to add additional state to the share mode lock struct that prevents any new opens from granting oplocks while a contending operation is in progress. All operations that contend level 2 oplocks are now correctly spanned except for aio and synchronous writes. The two write paths both have non-trivial error paths that need extra care to get right. RAW-OPLOCK and the rest of 'make test' are still passing with this change.
2009-02-09s3 oplocks: Differentiate between releasing an oplock vs. downgrading to ↵Tim Prouty1-2/+2
Level 2 for kernel oplocks Pass in an extra argument when releasing an oplock so kernel oplock implementations can support downgrading from Level 1 to Level 2.
2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-3/+6
This changelist allows for the addition of custom performance monitoring modules through smb.conf. Entrypoints in the main message processing code have been added to capture the command, subop, ioctl, identity and message size statistics.

2008-04-07locking: store the write time in the locking.tdbStefan Metzmacher1-3/+6
This is needed to implement the strange write time update logic later. We need to store 2 time timestamps to distinguish between the time the file system had before the first client opened the file and a forced timestamp update. metze (This used to be commit 6aaa2ce0eeb46f6735ec984a2e7aadde7a7f456d)

2008-01-04Refactor the crypto code after a very helpful conversationJeremy Allison1-13/+13

2007-12-30As the encryption is stream based there's no reasonJeremy Allison1-5/+7
oplock breaks can't be encrypted. If we have multiple contexts I should probably attach them to the connection struct, but for now use the global context number. Jeremy. (This used to be commit 5b4b335ed0d1dc738f1f099e5c638361f3aede07)

2007-10-10r23410: Merge the core of the cluster code.Volker Lendecke1-0/+6
I'm 100% certain I've forgotten to merge something, but the main code should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and messages_ctdbd.c. There should be no changes to the non-cluster case, it does survive make test on my laptop. It survives some very basic tests with ctdbd enables, I did not do the full test suite for clusters yet. Phew... Volker (This used to be commit 15553d6327a3aecdd2b0b94a3656d04bf4106323)
2007-10-10r23183: Check in a change made by Tridge:Volker Lendecke1-56/+38
This replaces the internal explicit dev/ino file id representation by a "struct file_id". This is necessary as cluster file systems and NFS don't necessarily assign the same device number to the shared file system. With this structure in place we can now easily add different schemes to map a file to a unique 64-bit device node. Jeremy, you might note that I did not change the external interface of smb_share_modes.c. Volker (This used to be commit 9b10dbbd5de8813fc15ebbb6be9b18010ffe8139)
