2010-06-12s3: Use "sconn" argument in smbd_[un]lock_socket_internalVolker Lendecke1-8/+8

2010-06-11s3: Fix starving the echo responderVolker Lendecke1-0/+11
When both the echo responder and the 445 socket want to send stuff to the worker smbd, the select loop is not fair. It always chooses the smaller file descriptor to work on. This can mean that on a busy system the echo responder never gets around to feed its stuff to the parent. This fix chooses the async echo responder socket when both the 445 and the echo responder socket are readable. Yes, it is a very hackish fix which is required *now* I think. The proper fix would be to either assign priorities to fd's in tevent, or the from my point of view better fix would be to make tevent kindof round-robin. Round-robin would mean that whenever a fd has been dealt with, it is taken off the list of interested sockets, and only if no other socket is active, all of the ones waiting are put back. This is a bit like EPOLL_ONESHOT, which I would like to use for this in the epoll case. Although, I need to do some research if maybe epoll already guarantees round-robin, I did not find anything in the docs yet. Volker

2010-05-31s3:smbd make yp cache local.Simo Sorce1-3/+0
The my_yp_domain variable is just a static cache needed to avoid making over and over expensive and potentially blocking calls to yp_get_default_domain(). Instead of keeping this onto the smbd_server_connection struct, just keep it local to the only function ever using this variable. This disentagle this function (and a number of calling functions) from having to pass around smbd_server_connection and thus having to link against smbd. It also removes a few ifdefs. Nothing changes from a global/local pov, as the smbd_server_connection variable passed around is also a global one. Signed-off-by: Andreas Schneider <asn@samba.org>

Jeremy.
2010-04-22Make deferred opens (NT_STATUS_SHARING_VIOLATION) work over SMB2.Jeremy Allison1-4/+4
Makes SMB2Create call re-entrant internally. Now this infrastructure is in place, oplocks will follow shortly. Tested with Win7 client and with W2K8R2. Jeremy.
2010-04-12Move to using 64-bit mid values in our internal open file database.Jeremy Allison1-33/+40
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 Allison1-19/+65
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/+1
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.
2010-04-07Start to plumb smb2 into the oplock system. Calls dummy functions for now.Jeremy Allison1-0/+6
Jeremy.
2010-04-01Move initialize_async_io_handler() inside of smbd/aio.c.Jeremy Allison1-3/+0
Call from actual aio read or write. No reason to call this globally on startup. Jeremy.
2010-03-31Make smbd_lock_socket/smbd_unlock_socket recursive with a ref_count.Jeremy Allison1-40/+38
As these always call exit_server, make that part of the function. Use _internal functions for the echo client. Metze please check ! Jeremy.

2009-09-06Fix bug 6673 - smbpasswd does not work with "unix password sync = yes".Jeremy Allison1-2/+2
Revert change from 3.3 -> 3.4 with read_socket_with_timeout changed from sys_read() to sys_recv(). read_socket_with_timeout() is called with non-fd's (with a pty in chgpasswd.c and with a disk file in lib/dbwrap_file.c via read_data()). recv works for the disk file, but not the pty. Change the name of read_socket_with_timeout() to read_fd_with_timeout() to make this clear (and add comments). Jeremy.

2009-07-17Move the initialization of smbd_server_conn from smbd/process,Jeremy Allison1-5/+0
after the accept and fork, to smbd_init_globals(), so it's done immediately on server startup. This is needed as some messages are sent to all active smbd processes (including the master listening daemon). If it gets a message that forces it to scan it's current connections (ie. conn_find()) then it discovers that sconn->smb1.tcons.Connections dereferences null (as sconn == NULL in the parent) and crashes. Yes, I could fix all cases where sconn is used and explicitly check for NULL but this fix is easier. It means that the smbd_event_context() is initialized in the master daemon and then re-initialized after fork, but that should be being done correctly in every fork call anyway. Without this change the previous fix 6a9e0039100b57f9626e87defec6720c476b9789 still panics in the reproducible test case for bug 6564, as this is one case where such a message (MSG_SMB_CONF_UPDATED) is sent to the parent. Metze please check. This change passes valgrind. Jeremy.

s3: Make smbd aware of permission change of usershare. Since usershare are relatively volatile and non-previledge users must disconnect from smbd and reconnect to it to make share permission in effect. For now. This is a feature request and I think we need to design it a little differently so as not to touch core change_to_user() code. Jeremy.
