2007-10-10r4143: Make strict locking an enum. Auto means use oplock optimization.Jeremy Allison1-9/+16
Jeremy. (This used to be commit 0dd4adeae2042d0ea64398a78b3f48eb0150c133)
2007-10-10r4121: Optimisation from Nadav Danieli <nadavd@exanet.com>. If we're oplocked,Jeremy Allison1-1/+9
short circuit some is_locked() tests. Jeremy. (This used to be commit f4feed8f90be98eaea59bebcc142fd398ffe2a59)
2007-10-10r4108: As check_self is *always* False in every invokation, remove theJeremy Allison1-5/+2
logic for it. We still pass Samba4 RAW-LOCK test. Jeremy. (This used to be commit 596f23051363f8cc8896119b3eca0663a61a38c3)
2007-10-10r4088: Get medieval on our ass about malloc.... :-). Take control of all our ↵Jeremy Allison1-4/+4
allocation functions so we can funnel through some well known functions. Should help greatly with malloc checking. HEAD patch to follow. Jeremy. (This used to be commit 620f2e608f70ba92f032720c031283d295c5c06a)
2007-10-10r2413: Arggg. Stupid, stupid, stupid me ! I added a paranoia testJeremy Allison1-13/+0
case when I was developing the deferred open case and made it too tight. It will fire (incorrectly) and panic when a client does a second open for a file with a different mid (multiplex-id) request. Doh ! This is a perfectly valid thing for a client to do (have two pending opens with different mids outstanding on the same file) and currently when the first pending open expires with a share violation the paranoia code will panic smbd. It's a rare condition, but obvious now I've looked at the code. Fix for bug #1743. Jeremy. (This used to be commit e1bf108ae965ae730c67524164fa36497ea905b5)
2007-10-10r1085: Now it's had some proper user testing, merge in the deferred open ↵Jeremy Allison1-5/+387
fix. I'm still doing more testing, but it fixes a behaviour that we've been wrong on ever since the start of Samba. Jeremy. (This used to be commit 894cc6d16296b934c112786eec896846156aee5d)
2007-10-10r1011: fix bad merge (from a few months ago) and ensure that we always use ↵Gerald Carter1-2/+2
tdb_open_log() instead of tdb_open_ex() (This used to be commit e65564ab4aa1240e84b8d272510aa770cad0ed0e)
2007-10-10r984: Ensure memmove & memcpy aren't called with len == 0.Jeremy Allison1-4/+8
Jeremy. (This used to be commit 40c77dddc65e18b879d922379d562ffb8be80ab5)
2004-02-12merge from old APP_HEADGerald Carter1-2/+2
* remove corrupt tdb and shutdown (only for printing tdbs, connections, sessionid & locking) * decrement smbd counter in connections.tdb in smb_panic() * various Makefile hack to get things to link 'max smbd processes' looks like it might be broken. The counter KEY is not being set. Will look into that tomorrow. (This used to be commit 6e22c5da929b6d9a4e32dc704c83112b2ad8fcfd)
2003-10-09Changes to allow Samba3 to pass the Samba4 RAW-READ tests.Jeremy Allison1-4/+7
Jeremy. (This used to be commit e7565dbba696adbb0fd8cca6b86a1a7e5a655f2e)
2003-09-08Tidy up some formatting. Get ready for allowing bad password lockout. (basedJeremy Allison1-14/+18
on a patch posted from Richard Renard <rrenard@idealx.com>. Jeremy. (This used to be commit abf54b58e95a949cb883d4485853dc560489c03f)
2003-08-01Final fix for the bug tridge found. Only push locks onto a blocking lockJeremy Allison1-1/+5
queue if the posix lock failed with EACCES or EAGAIN (this means another lock conflicts). Else return an error and don't queue the request. Jeremy. (This used to be commit 43fbc18fdc184bf29c15186c16bc99fb208de963)
2003-07-22Fixup a bunch of printf-style functions and debugs to use unsigned long whenTim Potter1-2/+2
displaying pid_t, uid_t and gid_t values. This removes a whole lot of warnings on some of the 64-bit build farm machines as well as help us out when 64-bit uid/gid/pid values come along. (This used to be commit f93528ba007c8800a850678f35f499fb7360fb9a)
2003-05-22More fixes for debug log to catch logic error.Jeremy Allison1-1/+1
Jeremy. (This used to be commit 84a7714eba801fefa7ad56493f20813de3943bc5)
2003-04-04Fix for very subtle POSIX lock interaction race condition found byJeremy Allison1-8/+28
Herb. We need to unlock POSIX locks before notifying pending lock processes. Jeremy. (This used to be commit 6999eef51c3e597b3b2cd9cc26138acdfbb6a23a)
2003-02-27Fix to allow blocking lock notification to be done rapidly (no waitJeremy Allison1-2/+2
for smb -> smb lock release). Adds new PENDING_LOCK type to lockdb (does not interfere with existing locks). Jeremy. (This used to be commit 766928bbba1e597c9c2b12458dd8d37e6080593e)

2003-02-10Cleanups: (merge from HEAD)Andrew Bartlett1-1/+3
- use safe_strcpy() instead of pstrcpy() for malloc()ed strings - CUPS: a failure in an attempt to automaticly add a printer is not level 0 stuff. - Fix up a possible Realloc() failure segfault Andrew Bartlett (This used to be commit c1cfc296c2efdb2b5972202146e80f0e3b6a3da4)

2002-03-23Fix the mp3 rename bug - also tidy up our open code and remove the specialJeremy Allison1-3/+4
cases for rename and unlink. Had to add desired_access into the share mode record. Jeremy. (This used to be commit 3b1b8ac43535fb0839c5474fa55bf7150f6cde31)
2002-03-15if our lock spin code fails then return the first error code, not theAndrew Tridgell1-4/+11
last one. This is what caused the lock1 and lock2 tests to fail. (This used to be commit e7ae8003cb4fdc93db5f842754884a6d2ec93dc0)

2002-03-13include/smb_macros.h: Don't round up an allocation if the size is zero.Jeremy Allison1-1/+25
"One of these locks is not like the others... One of these locks is not quite the same" :-). When is a zero timeout lock not zero ? When it's being processed by Windows 2000 of course.. This code change, ugly though it is - completely fixes the foxpro/access multi-user file system database problems that people have been having. I used a *wonderful* test program donated by "Gerald Drouillard" <gerald@drouillard.ca> which allowed me to completely reproduce this problem, and to finally determine the correct fix. This also explains why Windows 2000 is *so slow* when responding to the smbtorture lock tests. I *love* it when all these things come together and finally make sense :-). Jeremy. (This used to be commit 8aa9860ea2ea7f5aed4b6aa12794fffdfa81b0d0)
2002-03-10this attempts to handle the rather bizarre lock cache semantics inAndrew Tridgell1-1/+1
w2k. It isn't entirely accurate, but its close (This used to be commit e02d7364707c4939efa4ff0ddf9b6d4f48e5d411)
2002-01-30Removed version number from file header.Tim Potter1-2/+1
Changed "SMB/Netbios" to "SMB/CIFS" in file header. (This used to be commit 6a58c9bd06d0d7502a24bf5ce5a2faf0a146edfa)
2002-01-08Debugs that print out a share mode table in debug level 10. This codeJeremy Allison1-4/+46
enabled me to track down a *nasty* bug. Jeremy. (This used to be commit ed5a9a0ee32aec460b9247ab4e4f5e38e8149e08)
2002-01-05Added DEBUG in set_share_mode to track down logic insanity.Jeremy Allison1-0/+8
Jeremy. (This used to be commit 32f4f3a45d473b3be1ae07f6c60897c12323d60c)
2001-12-18Removed unused function, delete_fn()Tim Potter1-57/+0
(This used to be commit f26e8205cff63967b9c1659b8e6ad71cbe36dace)
2001-11-30After conversations with Andrew, improved the robustness of theJeremy Allison1-26/+53
sharemode db in the following way. Originally, on startup and shutdown, smbd would scan the share mode db to ensure it was correct. This lead to scalability issues as scans lock the db for quite a long time. Andrew had the brainstorm that we only care about the record we're about to read. This new code (small change really, but quite significant) causes get_share_modes() to do a process_exists() call against each pid in each record, and to delete any that don't and re-write the entry if any dead records were detected. This allowed me to remove the startup/shutdown scans of the db (they can be added into smbstatus if anyone really cares to have them back). This will please the vfs author who was worried about the time taken on open() calls, and will lead to much greater robustness and scalability in the share mode db. We need much testing of this, and also netbench tests to ensure the extra process_exists() calls don't hurt performance (they shouldn't it's a very simple system call). Jeremy. (This used to be commit 4098d442030e66601450baeb09ae06b39a1ab571)
2001-11-21Don't scan locking db on closedown.Jeremy Allison1-0/+4
Jeremy. (This used to be commit 59cfcd8a6c510204ac059a0d2fddc2fa17199f82)
2001-10-20Move from timestamp to gen count file id's for finding oplocked filesJeremy Allison1-6/+19
in a tdb. Jeremy. (This used to be commit 058ae6b58f61ef46013dd076af3a84de5fbaaab1)
2001-10-19Ensure we mask off deny modes correctly on being set (this shouldn't haveJeremy Allison1-2/+2
caused problems but is tidier). Fix debug statement in locking.c Jeremy. (This used to be commit eac6bbd24ebf00b35e50953bc11186111dc39059)
2001-10-02Removed 'extern int DEBUGLEVEL' as it is now in the smb.h header.Tim Potter1-1/+0
(This used to be commit 2d0922b0eabfdc0aaf1d0797482fef47ed7fde8e)
2001-09-19Removed test code that got added by accident.Jeremy Allison1-22/+0
Jeremy. (This used to be commit fc91ecc236e0d27f5836e9820332ababd762f1a7)
2001-09-18Correct fix for unaligned memcpy - malloc'ed memory incremented by ↵Jeremy Allison1-18/+20
sizeof(struct locking_data) was not forced to be 8 byte aligned. Use union to force it to be correctly aligned for memcpy and use void *, to tell compiler not to optimize aligned copy (this last fix suggested by Trond @ RedHat). The first fix should be sufficient, but this provides a "belt and braces" fix. Jeremy. (This used to be commit 22c5915bb466529ac1bcb5c2574888b360a9775b)
2001-09-18Use structure copy to fix unaligned accesses on 64bit architectures onJeremy Allison1-1/+1

(This used to be commit b1b2a5fa5d084dad8ae47777419ab75db1e51eff)
2001-09-052nd DELETE_ON_CLOSE_FLAG fix ...Andrew Tridgell1-3/+3
we set the DELETE_ON_CLOSE_FLAG on all share modes on the file, which means the share mode in the fsp will not match the one in the tdb when we come to close for other file handles, which means we end up with share modes on files after all handles are closed fixed by making the comparison function that says if two shares modes are equal ignore the DELETE_ON_CLOSE_FLAG (This used to be commit 7b39c4c59897669106d7129bad8af3d592d25838)

2001-08-27started converting NTSTATUS to be a structure on systems with gcc in order ↵Andrew Tridgell1-6/+6
to make it type incompatible with BOOL so we catch errors sooner. This has already found a number of bugs (This used to be commit 1b778bc7d22efff3f90dc450eb12baa1241cf68f)
2001-08-27converted smbd to use NTSTATUS by defaultAndrew Tridgell1-22/+13
major changes include: - added NSTATUS type - added automatic mapping between dos and nt error codes - changed all ERROR() calls to ERROR_DOS() and many to ERROR_NT() these calls auto-translate to the client error code system - got rid of the cached error code and the writebmpx code We eventually will need to also: - get rid of BOOL, so we don't lose error info - replace all ERROR_DOS() calls with ERROR_NT() calls but that is too much for one night (This used to be commit 83d9896c1ea8be796192b51a4678c2a3b87f7518)
