2009-07-27Fix a valgrind error in chain_replyVolker Lendecke1-3/+10
construct_reply() references the request after chain_reply has freed it.
2009-07-24In chain_reply, copy the subrequests' error to the main requestVolker Lendecke1-0/+15
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.
2009-07-14Revert this commit :Jeremy Allison1-56/+2
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.

2009-06-22s3: forward MSG_DEBUG from smbd parent to all childrenAravind Srinivasan1-0/+9
Before 3.3, an smbcontrol debug message sent to the target "smbd" would actually be sent to all running processes including nmbd and winbindd. This behavior was changed in 3.3 so that the "smbd" target would only send a message to the process found in smbd.pid, while the "all" target would send a message to all processes. The ability to set the debug level of all processes within a single daemon, without specifying each pid is quite useful. This was implemented in winbindd in 065760ed. This patch does the same thing for smbd. Upon receiving a MSG_DEBUG the parent smbd will rebroadcast it to all of its children. The printing process has been added to the list of smbd child processes, and we now always track the number of smbd children regardless of the "max smbd processes" setting.

2009-05-08s3: Fix chained sesssetupAndX/tconn messagesTim Prouty1-0/+7
A sesssetupAndX chained with a tconn will not correctly set the TID in the response header. I'm seeing an XP client send this chained sesssetup/tconn when samba has security = share. Samba's current behavior is to return a TID of 0 in the smb header rather than the actual TID. This patch also updates the UID in the header as well.

2009-03-23s3:smbd: use new simplified snb_signing code in the serverStefan Metzmacher1-15/+35
We keep the seqnum/mid mapping in the smb_request structure. This also moves one global variable into the smbd_server_connection struct. metze

2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-16/+45
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.

This is a hack to fix races which happen with the RAW-RENAME and RAW-OPLOCK tests. We should try to remove it later. metze

2009-01-16Add a new implementation of chain_replyVolker Lendecke1-0/+217
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.

2009-01-09s3:smbd: handle incoming smb requests via event handlersStefan Metzmacher1-108/+155
We use a fd event and receive incoming smb requests when the fd becomes readable. It's not completely nonblocking yet, but it should behave like the old code. We use timed events to trigger retries for deferred open calls. metze

2008-12-31Replace "goto again" by "return NT_STATUS_RETRY" in receive_message_or_smbVolker Lendecke1-11/+13

2008-11-04Make "inbuf" a talloc child of "smb_request" for normal smb requestsVolker Lendecke1-3/+2
This is necessary if we want to keep the whole smb_request for deferred ops. The explicit settings of req->inbuf will be removed once all those deferring operations are converted to store the whole request and not just the inbuf.
2008-11-04Add construct_reply_common_req wrapperVolker Lendecke1-0/+5
The goal is to remove the remaining direct calls to construct_reply_common.
