2009-11-23Revert "s3: Move the global variable Protocol to struct smbd_server_connection"Volker Lendecke1-1/+0

2009-10-01Fix for CVE-2009-2906.Jeremy Allison1-5/+25
Summary: Specially crafted SMB requests on authenticated SMB connections can send smbd into a 100% CPU loop, causing a DoS on the Samba server.

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.
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.
