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)
2007-10-10r22868: Replace some message_send_pid calls with messaging_send_pid calls. MoreVolker Lendecke1-2/+4
tomorrow. (This used to be commit 74fa57ca5d7fa8eace72bbe948a08a0bca3cc4ca)
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)
2007-10-10r22784: fixed change notify for delete on closeAndrew Tridgell1-0/+4

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)
2007-10-10r21409: saved_status1 is not used anymore after aio write behind was removedVolker Lendecke1-5/+2

2007-10-10r21279: Get rid of 'aio write behind', this is broken.Volker Lendecke1-12/+1
It should probably better be integrated with our write cache. Volker (This used to be commit 58bfd168b046a97a895aaa3384fd7af8d077a1d5)
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)
2007-10-10r20916: Add in the delete on close final fix - but only enabledJeremy Allison1-0/+1
with -DDEVELOPER. Jeremy. (This used to be commit 7f817067a70930ee3502ea3373173e0c23733253)
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. (This used to be commit f2df77a1497958c1ea791f1d2f4446b5fc3389b3)

2007-10-10r20525: Closing a dir with del-on-close set requires the same as files: ↵Volker Lendecke1-0/+12
Don't actually unlink/rmdir if another process still has it open. Jeremy, this is a potential merger to 3.0.24. Volker (This used to be commit 8e1e896b02da99b5a48883c5f37fe146ad0fb5ce)
2007-10-10r20524: Simplify logic of close_remove_share_mode().Volker Lendecke1-51/+67
Volker (This used to be commit ade90dbf0c2cbd2cc49a6357f3dd220ea82fd215)
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
test. Phew - that was painful :-). But what it means is that we now implement lock cancels and I can add lock cancels into POSIX lock handling which will fix the fast/slow system call issue with cifsfs ! Jeremy. (This used to be commit f1a9cf075b87c76c032d19da0168424c90f6cb3c)
2007-10-10r15668: DOS or FCB opens share one share mode entry from differentJeremy Allison1-65/+73
fsp pointers. Ensure we cope with this to pass Samba4 DENY tests (we used to pass these, there must have been a regression with newer code). We now pass them. Jeremy (This used to be commit fd6fa1d4eaf61783df74ee2da50d331477f06998)

Jeremy, can you check this? Thanks, Volker (This used to be commit f66b9701b5c6bb6302fa11889adab6902cbaf2e3)
2007-10-10r13748: Don't reference memory after we just freed it (Doh!).Jeremy Allison1-2/+3
Thanks to tridge's changes to the directory delete on close tests for catching this. Jeremy. (This used to be commit 01ef957d4846191071f95393e6e76e48d4c6aa24)

2007-10-10r13293: Rather a big patch I'm afraid, but this should fix bug #3347Jeremy Allison1-15/+51
by saving the UNIX token used to set a delete on close flag, and using it when doing the delete. libsmbsharemodes.so still needs updating to cope with this change. Samba4 torture tests to follow. Jeremy. (This used to be commit 23f16cbc2e8cde97c486831e26bcafd4ab4a9654)
2007-10-10r13274: Fix for bug #3467. Not a show stopper.Jeremy Allison1-2/+2

always linearize into little-endian. Should fix all Solaris issues with this, plus provide a cleaner base moving forward for cluster-aware Samba where smbd's can communicate across different compilers/architectures (eventually these message will have to go cross-machine).

that have open file handles to allow them to correctly implement delete on close. There is a further correctness fix I'm intending to add to this to cope with different share paths, but not right now... Jeremy. (This used to be commit 932e337db8788e75344e1c7cf1ef009d090cb039)
2007-10-10r12203: Add the share path into the sharemode db. This involvesJeremy Allison1-2/+2
revving the minor version number for libsmbsharemodes (we now have a new _ex interface that takes the share path as well as the filename). Needed for #3303. Some code written by SATOH Fumiyasu <fumiya@samba.gr.jp> included in the changes to locking/locking.c. The smbstatus output is a bit of a mess and needs overhauling... Jeremy.

2007-10-10r12160: The filename parameter to get_share_mode_lock is goingJeremy Allison1-2/+2
