2009-02-09s3 oplocks: Remove oplocks before handling delete on close semanticsTim Prouty1-4/+5
Unlinking a file while still holding an oplock can cause problems with kernel oplocks. This simply releases the oplock before actually unlinking the file.
2009-02-09s3 oplocks: Add capabilites flags field to the kernel_oplocks structTim Prouty1-0/+4
Here is a short description for each of the new capability flags: KOPLOCKS_LEVEL2_SUPPORTED: Level 2 oplocks are supported natively in the kernel. KOPLOCKS_DEFERRED_OPEN_NOTIFICATION: The kernel notifies deferred openers when they can retry the open. KOPLOCKS_TIMEOUT_NOTIFICATION: The kernel notifies smbds when an oplock break times out. KOPLOCKS_OPLOCK_BROKEN_NOTIFICATION: The kernel notifies smbds when an oplock is broken.
2009-01-23Extend NTIMES to allow setting create_timetodd stecher1-4/+4
1) Add in smb_file_time struct to clarify code and make room for createtime. 2) Get and set create time from SMB messages. 3) Fixup existing VFS modules + examples Some OS'es allow for the setting of the birthtime through kernel interfaces. This value is generically used for Windows createtime, but is not settable in the code today.
2009-01-09s3: Add delete_all_streams to proto.hTim Prouty1-1/+1

monyo@samba.gr.jp. Jeremy.
2008-12-09s3: Call fd_close from close_directoryTim Prouty1-0/+7
Some implementations of SMB_VFS_CREATE_FILE implementations actually keep an fd open for directories just as files. In this case it is necessary to call fd_close when closing directories. This is safe because fd_close is a no-op when fd == -1, which is true for directory opens originating from open.c (the default SMB_VFS_CREATE_FILE implementation).
2008-11-21First part of fix for bug #5903 - vfs_streams_xattr breaks contents of the file.Jeremy Allison1-5/+3
Restructures parts of open code so that fsp must be allocated before calling open_file_ntcreate(_internal). Also fix up file ref-counting inside files.c. Jeremy.

2008-04-07smbd: implement the strange write time update logicStefan Metzmacher1-5/+73
We now never call file_ntimes() directly, every update is done via smb_set_file_time(). This let samba3 pass the BASE-DELAYWRITE test. The write time is only updated 2 seconds after the first write() on any open handle to the current time (not the time of the first write). Each handle which had write requests updates the write time to the current time on close(). If the write time is set explicit via setfileinfo or setpathinfo the write time is visible directly and a following close on the same handle doesn't update the write time. metze (This used to be commit 2eab212ea2e1bfd8fa716c2c89b2c042f7ba12ea)
2008-04-07locking: store the write time in the locking.tdbStefan Metzmacher1-2/+4
This is needed to implement the strange write time update logic later. We need to store 2 time timestamps to distinguish between the time the file system had before the first client opened the file and a forced timestamp update. metze (This used to be commit 6aaa2ce0eeb46f6735ec984a2e7aadde7a7f456d)
2008-04-01smbd: always close the base_fsp even if the real close returned an errorStefan Metzmacher1-4/+0
Otherwise we may end up with share mode entry without an open file. Volker, Jeremy: please check... metze (This used to be commit 547eacf6058d2bc5b41b266b70f8f4747aca4eae)
2008-01-19Add streams supportVolker Lendecke1-4/+111
This is the core of the streams support. The main change is that in files_struct there is now a base_fsp pointer that holds the main file open while a stream is open. This is necessary to get the rather strange delete semantics right: You can't delete the main file while a stream is open without FILE_SHARE_DELETE, and while a stream is open a successful unlink of the main file leads to DELETE_PENDING for all further access on the main file or any stream. (This used to be commit 6022873cc155bdbbd3fb620689715f07a24d6ed1)

2007-10-10r23183: Check in a change made by Tridge:Volker Lendecke1-7/+10
This replaces the internal explicit dev/ino file id representation by a "struct file_id". This is necessary as cluster file systems and NFS don't necessarily assign the same device number to the shared file system. With this structure in place we can now easily add different schemes to map a file to a unique 64-bit device node. Jeremy, you might note that I did not change the external interface of smb_share_modes.c. Volker (This used to be commit 9b10dbbd5de8813fc15ebbb6be9b18010ffe8139)

2007-10-10r22846: Chunk one to replace message_send_pid with messaging_send: Deep insideVolker Lendecke1-1/+1
locking/locking.c we have to send retry messages to timed lock holders. The majority of this patch passes a "struct messaging_context" down there. No functional change, survives make test. (This used to be commit bbb508414683eeddd2ee0d2d36fe620118180bbb)

2007-10-10r21714: Change the VFS interface to use struct timespecJeremy Allison1-2/+2
for utimes - change the call to ntimes. This preserves nsec timestamps we get from stat (if the system supports it) and only maps back down to usec or sec resolution on time set. Looks bigger than it is as I had to move lots of internal code from using time_t and struct utimebuf to struct timespec. Jeremy. (This used to be commit 8f3d530c5a748ea90f42ed8fbe68ae92178d4875)

2007-10-10r21274: As we now have POSIX opens which can unlinkJeremy Allison1-0/+9
with other open files we may have taken the delete code path with more than one share mode entry - ensure we only delete once by resetting the delete on close flag. Jeremy. (This used to be commit 429dff31663e71556b5193b25d5b8e7e09fa5b9c)
2007-10-10r21191: Add in the POSIX open/mkdir/unlink calls.Jeremy Allison1-55/+56
Move more error code returns to NTSTATUS. Client test code to follow... See if this passes the build-farm before I add it into 3.0.25. Jeremy. (This used to be commit 83dbbdff345fa9e427c9579183f4380004bf3dd7)
2007-10-10r20931: This changes the notify infrastructure from a polling-based to an ↵Volker Lendecke1-5/+0
event-driven based approach. The only remaining hook into the backend is now void *(*notify_add)(TALLOC_CTX *mem_ctx, struct event_context *event_ctx, files_struct *fsp, uint32 *filter); (Should we put this through the VFS, so that others can more easily plug in?) The trick here is that the backend can pick filter bits that the main smbd should not handle anymore. Thanks to tridge for this idea. The backend can notify the main smbd process via void notify_fsp(files_struct *fsp, uint32 action, char *name); The core patch is not big, what makes this more than 1800 lines are the individual backends that are considerably changed but can be reviewed one by one. Based on this I'll continue with inotify now. Volker (This used to be commit 9cd6a8a82792b7b6967141565d043b6337836a5d)

2007-10-10r20883: W00t! I now understand how "delete on close" reallyJeremy Allison1-2/+37
works - even with the strange "initial delete on close" semantics. The "initial delete on close" flag isn't committed to the share mode db until the handle is closed, and is discarded if any real "delete on close" was set. This allows me to remove the "initial_delete_on_close" flag from the share db, and move it into a BOOL in files_struct. Warning ! You must do a make clean after this. Cope with the wrinkle in directory delete on close which is done differently from files. We now pass all Samba4 smbtortute BASE-DELETE tests except for the one checking that files can't be created in a directory which has the delete on close set (possibly expensive to fix). Jeremy.

2007-10-10r20442: Slight rewrite of the change notify infrastructure. This now ↵Volker Lendecke1-1/+2
survives the first of the raw-notify subtests, the one-level test_notify_dir without any flags around yet. The tricky part was getting the data structures right, I hope the next tests don't let that fall over. fsp->notify is now by default NULL, meaning that nobody has issued a changenotify call. This means nobody is interested in changes for this directory. If that has happened, notify_change_buf collects the changes if no current request is outstanding, and it collects the requests if no change has happened since the last request. Happy New Year, somewhere on this planet it's already 2007 :-) Volker P.S: Jeremy, there's a question for you in smbd/files.c line 367. (This used to be commit ce0ad24988075465addcac0b9afc872e909135af)
2007-10-10r17293: After the results from the cluster tests in Germany,Jeremy Allison1-2/+0
fix the messaging code to call the efficient calls : save_re_uid() set_effective_uid(0); messaging_op restore_re_uid(); instead of using heavyweight become_root()/unbecome_root() pairs around all messaging code. Fixup the messaging code to ensure sec_init() is called (only once) so that non-root processes still work when sending messages. This is a lighter weight solution to become_root()/unbecome_root() (which swaps all the supplemental groups) and should be more efficient. I will migrate all server code over to using this (a similar technique should be used in the passdb backend where needed). Jeremy. (This used to be commit 4ace291278d9a44f5c577bdd3b282c1231e543df)
2007-10-10r17098: Samba3 now cleanly passes Samba4 RAW-LOCK tortureJeremy Allison1-2/+0
