2010-06-09Rename "allow_smb2" -> "using_smb2" and make the usage clearer.Jeremy Allison1-3/+3
2010-05-07This patch looks bigger than it is. It does 2 things. 1). Renames smbpid -> ↵Jeremy Allison1-27/+27
smblctx in our locking code. 2). Widens smblctx to 64-bits internally. Preparing to use the SMB2 handle as the locking context. Jeremy.

2010-04-30Plumb the SMB2 front end into the blocking lock backend.Jeremy Allison1-5/+16
Metze, you'll probably be happier with this work as it doesn't abuse tevent in the way you dislike. This is a first cut at the code, which will need lots of testing but I'm hoping this will give people an idea of where I'm going with this. Jeremy.

2010-04-12Move to using 64-bit mid values in our internal open file database.Jeremy Allison1-2/+2
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 Allison1-1/+1
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.
2010-04-08Stop smb2 from calling into smb1 blocking lock request code.Jeremy Allison1-0/+14
Allocate a uint16_t internal SMB1 mid for an SMB2 request. Add a back pointer from the faked up smb_request struct to the smb2 request. Getting ready to add restart code for blocking locks, share mode violations and oplocks in SMB2. Jeremy.
2010-02-12s3/smbd: change locking behavior when "lock spin time = 0".Steven Danneman1-1/+1
The "lock spin time" parameter mimics the following Windows setting which by default is 250ms in Windows and 200ms in Samba. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\LockViolationDelay When a client sends repeated, non-blocking, contending BRL requests to a Windows server, after the first Windows starts treating these requests as timed blocking locks with the above timeout. As an efficiency, I've changed the behavior when this setting is 0, to skip this logic and treat all requests as non-blocking locks. This gives the smbd server behavior similar to the 3.0 release with the do_spin_lock() implementation. I've also changed the blocking lock parameter in the call from push_blocking_lock_request() to true as all requests made in this path are blocking by definition.

2010-02-05s3-brlock: add a minimim retry time for pending blocking locksAndrew Tridgell1-0/+20
When we are waiting on a pending byte range lock, another smbd might exit uncleanly, and therefore not notify us of the removal of the lock, and thus not trigger the lock to be retried. We coped with this up to now by adding a message_send_all() in the SIGCHLD and cluster reconfigure handlers to send a MSG_SMB_UNLOCK to all smbd processes. That would generate O(N^2) work when a large number of clients disconnected at once (such as on a network outage), which could leave the whole system unusable for a very long time (many minutes, or even longer). By adding a minimum re-check time for pending byte range locks we avoid this problem by ensuring that pending locks are retried at a more regular interval.
2009-10-26Second part of the fix for bug 6828 - infinite timeout occurs when byte lock ↵Jeremy Allison1-6/+9
held outside of samba. Fixes case where a connection with a pending lock can me marked "idle", and ensures that the lock queue timeout is always recalculated. Jeremy.

2009-03-23s3:smbd: use new simplified snb_signing code in the serverStefan Metzmacher1-3/+2
We keep the seqnum/mid mapping in the smb_request structure. This also moves one global variable into the smbd_server_connection struct. metze
2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch1-48/+59
This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS, BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically: * I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to *_default as the default implementations of the VFS ops. * The blocking_lock_record (BLR) is now passed into the brl_lock_windows and brl_cancel_windows paths. The Onefs implementation uses it - future implementations may find it useful too. * Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a lock_struct and call either the Posix or Windows lock function. These happen to be the same for the default implementation. * Added helper functions: increment_current_lock_count() and decrement_current_lock_count(). * Minor spelling correction in brl_timeout_fn: brl -> blr. * Changed blocking_lock_cancel() to return the BLR that it has cancelled. This allows us to assert its the lock that we wanted to cancel. If this assert ever fires, this path will need to take in the BLR to cancel, rather than choosing on its own. * Adds a small helper function: find_blocking_lock_record_by_id(). Used by the OneFS implementation, but could be useful for others.

2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-2/+4
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.
2009-01-31Remove the global variable "chain_size"Volker Lendecke1-6/+1
2009-01-16Add a new implementation of chain_replyVolker Lendecke1-6/+0
This the global variable "orig_inbuf" in the old chain_reply code. This global variable was one of the reasons why we had the silly restriction to not allow async requests within a request chain.
