* s3:smbd: Fix Coverity ID 937, REVERSE_INULLVolker Lendecke2009-09-041-2/+2

* Hopefully last part of the fix for bug 6651 - smbd SIGSEGV when breaking ↵Jeremy Allison2009-09-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | oplocks. This one is subtle. There is a race condition where a signal can be queued for oplock break, and then the file can be closed by the client before the signal can be processed. Currently if this occurs we panic (we can't match an incoming signal fd with a fsp pointer). Simply log the error (at debug level 10 right now, might be too much) and then return without processing the break request. It looks like there is another race condition with this fix, but here's why it won't happen. If the signal was pending (caused by a kernel oplock break from a local file open), and the client closed the file and then re-opened another file which happened to use the same file descriptor as the file just closed, then theoretically the oplock break requests could be processed on the wrong fd. Here's why this should be very rare.. Processing a pending signal always take precedence over an incoming network request, so as long as the client close request is non-chained then the break signal should always be harmlessly processed *before* the open can be called. If the open is chained onto the close, and the fd on the new open is the same as the old closed fd, then it's possible this race will occur. However, all that will happen is that we'll lose the oplock on this file. A shame, but not a fatal event. Jeremy.
* s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan2009-08-285-24/+92
| | | | | | | | | | | This vop is designed to work in tandem with SMB_VFS_READDIR to allow vfs modules to make modifications to arbitrary filenames before they're consumed by callers. Subsequently the core directory enumeration code in smbd is now changed to free the memory that may be allocated in a module. This vop enables the new version of catia in the following patch.

* s3:streams: check for :$DATA only in the backend (fix bug #6642)Stefan Metzmacher2009-08-271-3/+0
| | | | | | | We need to allow "\\$Extend\\$Quota:$Q:$INDEX_ALLOCATION" to pass check_path(), so that the Quota Dialog works. metze
* s3/smbd: open the share_info.tdb on startup instead of tconxSteven Danneman2009-08-261-0/+9
| | | | | | | | This is a small performance optimization. Instead of opening the tdb on every smb connection in the forked child process, we now open it in the parent and share the fd. This also reduces the total fd usage in the system.
* Help debug for bug 6651 - smbd SIGSEGV when breaking oplocks.Jeremy Allison2009-08-241-0/+4
| | | | | | Should help track if we get invoked with an invalid fd from the signal handler. Jeremy.
* Second attempt at fix for bug 6529 - Offline files conflict with Vista and ↵Jeremy Allison2009-08-247-94/+62

* Second part of fix for 6529 - Offline files conflict with Vista and Office 2003.Jeremy Allison2009-08-241-0/+11
| | | | | | ext4 may be able to store ns timestamps, but the only API to *set* timestamps takes usec, not nsec. Round to usec on set requests. Jeremy.

* Fix bug 6529 - Offline files conflict with Vista and Office 2003Jeremy Allison2009-08-213-1/+27
| | | | | | | | On filesystems that can't store less than one second timestamps, round the incoming timestamp set requests so the client can't discover that a time set request has been truncated by the filesystem. Needs backporting to 3.4, 3.3, 3.2 and (even) 3.0. Jeremy

* Fix BASE-DELAYWRITE test by removing const from struct smb_filenameJeremy Allison2009-08-123-21/+21
| | | | | | | | in smbd_do_qfilepathinfo(). update_stat_ex_mtime() modifies the stat struct inside the smb_fname so don't make a copy of that stat struct, use it directly - it's meant to be updated and represent the state of the file we're returning. Jeremy.
* Add "store create time" parameter (docs to follow)Jeremy Allison2009-08-125-13/+106

* Correctly send out notify messages for timestamp changes.Jeremy Allison2009-08-071-5/+3
| | | | | | | "change time" has no notify message, so don't send anything out when we change it. Use FILE_NOTIFY_CHANGE_CREATION correctly when changing the create time. Jeremy.

* s3: Fix a bug in renames of directoriesTim Prouty2009-08-061-6/+19
| | | | | | | | | Recently code was added to match windows semantics of denying the rename of a directory if there are open files underneath it. This does partly match windows semantics, but it turns out the rename should be allowed if the open file handle is for the directory being renamed, or for a stream on the directory being renamed. This patch refines the check to better follow these rename semantics.
