2000-01-16added code to allow traversal of the byte range lock databaseAndrew Tridgell1-1/+1
this is used with "smbstatus -B" to dump the lock list (This used to be commit 5f022629146701e6d543f77007dc944e4277ab0c)
2000-01-14damn, Solaris already has a "enum lock_type"Andrew Tridgell1-2/+2
changed it to "enum brl_type" (This used to be commit 6b9ee7662c7afa70f6b20889e6b0ae1dcd677f9f)
2000-01-14we now pass all byte range locking testsAndrew Tridgell1-2/+15
the last piece was to use a smb timeout slightly larger than the locking timeout in bloking locks to prevent a race (This used to be commit 1b54cb4a33a65e62c2e3189b78ef073869a60c75)
2000-01-14some more work on the byte range lockingAndrew Tridgell1-6/+8
note the ugly global_smbpid - I hope that won't bethere for long, I just didn't want to do two lots of major surgery at the one time. Using global_smbpid avoids the big change of getting rid of our inbuf/outbuf interface to reply routines. I'll do that once the locking stuff passes all tests. (This used to be commit f8bebf91abcaa5bda3ec8701f9242f220da8943a)
2000-01-13the bulk of the new byte range locking coodeAndrew Tridgell1-45/+21
it doesn't map to posix locks yet, that will come later. (This used to be commit 7f2a493095887cb0aae915ac36b9cded71d3a7a7)
2000-01-03added the unexpected packet database (unexpected.tdb)Andrew Tridgell1-1/+1
this means "nmblookup -S" now always works, even with broken servers the database stores all unexpected replies and these can be accessed by any client. while doing this I cleaned up a couple of functions, and put in place a better trn_id generator. in most places the code got quite a bit simpler due to the addition of simple helper functions. I haven't yet put the code in to take advantage of this for pdc replies - that will be next. Jeremys pdc finding code will then work :) (This used to be commit 280e6359d36c9bc8dcded302f15c3a1db8e3feeb)
2000-01-02- added tdb_flags option to tdb_open()Andrew Tridgell1-1/+1
- added TDB_CLEAR_IF_FIRST flag to clear the database if this is the first attached process. Useful for non-persistent databases like our locking area (this will also make upgrades to new database layouts easier) - use lock_path() in a couple of places - leave connections database open while smbd running - cleaned up some tdb code a little, using macros for constants (This used to be commit 00e9da3ca577527db392aced62f02c69cfee8f4f)
1999-12-22when no shares are returned the *shares pointer must be set to nullAndrew Tridgell1-0/+2
(This used to be commit 84fe2337c701a52c6dc5cd8c1f6e9050478703f1)
1999-12-21converted all our existing shared memory code to use a tdb databaseAndrew Tridgell1-128/+295
instead of either sysv or mmap shared memory or lock files. this means we can now completely remove locking_shm.c locking_slow.c shmem.c shmem_sysv.c and lots of other things also got simpler locking.c got a bit larger, but is much better compartmentalised now (This used to be commit e48c2d9937eea0667b8cd3332e49c06314ef31e7)
1999-12-13first pass at updating head branch to be to be the same as the SAMBA_2_0 branchAndrew Tridgell1-22/+62
(This used to be commit 453a822a76780063dff23526c35408866d0c0154)
1999-04-04Use VFS operations for file I/O.Tim Potter1-4/+5
(This used to be commit 20bfa71c951a6e6018aafbd43946d1e0669feacb)
1998-10-31don't core dump in smbstatus if we can't open the shmem systemAndrew Tridgell1-0/+1
(This used to be commit ef9749798ab72a5e26f9cb5d0904266d6df70f8c)
1998-10-23Reasonably large change to give us *exactly* correct NT delete on close ↵Jeremy Allison1-2/+43
semantics. This was trickier than it looks :-). Check out the new DELETE_ON_CLOSE flag in the share modes and the new code that iterates through all open files on the same device and inode in files.c and trans2.c Also changed the code that modifies share mode entries to take generic function pointers rather than doing a specific thing so this sort of change should be easier in the future. Jeremy. (This used to be commit 5e6a7cd99d29d1cf068fc517272559c1cf47ea3a)
1998-09-05ahh, the joy of deleting large chunks of code that someone else hasAndrew Tridgell1-10/+0
painstakingly put in :) This gets rid of most of the #ifdef LARGE_SMB_INO_T ifdefs around DEBUG() statements. We just use %.0f in all cases. Makes the code a bit easier to read :) (This used to be commit 41f0069afc02169932e04ff0039bb6328eaaf04d)
1998-09-04More 64 bit stuff - now the fcntl locks are 64 bit clean.Jeremy Allison1-16/+25
Nearly at the stage where I can expose the 64-bit-ness to the NT clients.... Jeremy. (This used to be commit 422f1dd45074c0e28203aca5952e57bbe56676b6)
1998-08-31configure.in, configure: include/config.h.in: Added stropts and poll.Jeremy Allison1-3/+3
include/smb.h: Moved old typedefs of uint8 etc. into include/includes.h where all the other defines live (changed them from typedefs to defines). Other changes : changed from using uint32 to SMB_DEV_T and SMB_INO_T in preparation for moving to size independed (ie. 64 bit clean) device and inode access. Stat call wrapper comes next :-). Jeremy. (This used to be commit 3d9ec96de5e04e83abafe9c5d980bd39eee856ea)
1998-08-20Turning on blocking locking code. NB. Blocking lock requests that are notJeremy Allison1-0/+6
the head of an SMB request (ie. are part of a chain) will not be queued - this will be fixed when we move to the new chain code. In practice, this doesn't seem to cause much of a problem (in my admittedly limited testing) bug a debug level zero message will be placed in the log when this happens to help determine how real the problem is. smbd/locking.c: New debug messages. smbd/blocking.c: New blocking code - handles SMBlock, SMBlockread and SMBlockingX smbd/chgpasswd.c: Fix for master fd leak. smbd/files.c: Tidyup comment. smbd/nttrans.c: Added fnum to debug message. smbd/process.c: Made chain_reply() use construct_reply_common(). Added blocking lock queue processing into idle loop. smbd/reply.c: Added queue pushes for SMBlock, SMBlockread and SMBlockingX. Jeremy. (This used to be commit e1dd03ecda0bc6d7eaa31070c83774bb5679fd1b)
1998-08-19Makefile.in: Moved blocking lock code into smbd/blocking.c for link purposes.Jeremy Allison1-290/+0
include/includes.h: Added nterr.h. locking/locking.c: Moved blocking lock code into smbd/blocking.c for link purposes. smbd/close.c: Added blocking lock removal to file close. smbd/filename.c: Tidied up unix_convert() so I could read it (:-) in preparation for the stat_cache code. smbd/nttrans.c: Added WRITE_ATTRIBUTES check. smbd/reply.c: Fixed multibyte char problem in wildcard mask. Jeremy. (This used to be commit 148eaba3dadb1d0bd3ac3ef53da3d9811636e89a)
1998-08-17smbd/nttrans.c: Fixed bug in split off pipe code.Jeremy Allison1-4/+12
locking/locking.c: More blocking lock changes. Jeremy. (This used to be commit 2ca4fc95a4227645f1009a057d46b58508846a92)
1998-08-17much cleaner chain pointer handling for both files and pipes.Andrew Tridgell1-7/+6
the chain pointer is now stored as a static and is set whenever a handle is created or extracted. This also makes the code less error prone. (This used to be commit 068a862982bea726e8d7b1b4065d510b9840a272)
1998-08-16server.c: fixed a bug in close_file() with the new files.c handling codeAndrew Tridgell1-2/+0
bitmap.c: added bitmap hanlding code in preparation for increasing the default max open files to several thousand (This used to be commit f573a65b67e7a57586fec57845598e49b157ee0a)
1998-08-15this checkin gets rid of the global Files[] array and makes it localAndrew Tridgell1-31/+25
in files.c it should now be faily easy to expand the default MAX_OPEN_FILES to many thousands. (This used to be commit b088c804f98908eb02f05ab2f2e8a61691a0a582)
1998-08-14this is the bug change to using connection_struct* instead of cnum.Andrew Tridgell1-48/+39
Connections[] is now a local array in server.c I might have broken something with this change. In particular the oplock code is suspect and some .dll files aren't being oplocked when I expected them to be. I'll look at it after I've got some sleep. (This used to be commit c7ee025ead4a85b6fa44a832047b878451845fb6)
1998-08-14Makefile.in: Changed so that make proto will work with ldap & nisplus.Jeremy Allison1-3/+3
locking/locking.c: Made #ifdef'ed out functions static for Make proto. lib/util.c: Re-instated old mask_match code for UNIX filesystem checks only. Client calls use the new mask_match code. Changed the name of the old function to unix_mask_match. Jeremy. (This used to be commit b68e756ff57622c6c74f28031d4be964d7b1c9bc)
1998-08-13More blocking lock code - still #ifdef'ed out - under development.Jeremy Allison1-10/+170
Jeremy. (This used to be commit c9695bdf2e22c3081841f116af37340308d447aa)
1998-08-12fixed the nested comment - Jeremy, do you want that unbecome_user() orAndrew Tridgell1-2/+1
not? (This used to be commit 638ee7d265982ca95ae7f49e2a84431bdf147c21)
1998-08-11include/smb.h: Removed dir_ptr. Not needed.Jeremy Allison1-5/+139
locking/locking.c: First cut a blocking lock code. #ifdef'ed out for now. locking/locking_shm.c: Removed dir_ptr. Not needed. smbd/nttrans.c: More work on ChangeNotify - return is not an error and needs to be handled as a nttrans with zero params. Removed dir_ptr. Not needed. smbd/reply.c: smbd/server.c: smbd/trans2.c: Removed dir_ptr. Not needed. Hmmm. At the moment smbclient is broken - doesn't issue prompt correctly. This needs looking at. Jeremy. (This used to be commit ddfbcc05815621d3c463f92faed047f126412342)
1998-07-30Makefile.in: Moved UBIQX stuff into UTILOBJ.Jeremy Allison1-5/+5
loadparm.c: Added "ole locking compatibility" option (default "true"). locking.c: Changes to implement union in files_struct. locking_shm.c: Changes to implement union in files_struct. nttrans.c: Made opening a directory explicit (we have to). Added create directory code for nttrans. reply.c: Changes to implement union in files_struct. server.c: Changes to implement union in files_struct. Added create directory code. trans2.c: Changes to implement union in files_struct. smb.h: Changes to implement union in files_struct. util.c: Changed linked list code to UNIQX linked list. This will make the other lists I need to implement for ChangeNotify and blocking locks easier. Jeremy. (This used to be commit 3a5eea850bb256b39cff8ace1e4fb4e0c1f5472b)
1998-07-29merge from the autoconf2 branch to the main branchAndrew Tridgell1-7/+4
(This used to be commit 3bda7ac417107a7b01d91805ca71c4330657ed21)
1998-07-29locking.c: Print messages when we downgrade a lock.Jeremy Allison1-0/+2
reply.c: Do the same mask expansion we do in trans2.c - needed for Win98. trans2.c: Make the mask expansion into a function call now we have to do it twice. Jeremy. (This used to be commit 7b3a9d6285cc0d1967155a68845e28c6296ecc67)
1998-07-28locking.c: Don't need to do map_lock_type on *testing* a lock, just on setting.Jeremy Allison1-2/+7
Jeremy. (This used to be commit 17f68cc86cafbb04dbd9cc6ecc0aac7b911c9b70)
1998-07-28loadparm.c: Added strict sync parameter.Jeremy Allison1-10/+34

1998-07-23locking.c: Added lock type to is_locked() and do_lock()Jeremy Allison1-27/+47
as the code in reply_lockingX wasn't taking account of the difference between read and write locks ! How did this ever work :-) ! reply.c: server.c: Add lock type to is_locked() and do_lock(). util.c: Also added code from klausr@ITAP.Physik.Uni-Stuttgart.De to fix problem with log files growing too large if an smbd writes less than 100 debug messages. Jeremy. (This used to be commit 80080abf772a470d5f0f4dcd4a75fb2a09a9fb2a)
1998-01-22This is *not* a big change (although it looks like one).Jeremy Allison1-1/+1
This is merely updating the Copyright statements from 1997 to 1998. It's a once a year thing :-). NO OTHER CHANGES WERE MADE. Jeremy. (This used to be commit b9c16977231efb274e08856f7f3f4408dad6d96c)
1997-10-29- don't allow locking to initialise twiceAndrew Tridgell1-1/+5
- check that it is initialised before de-initialising it! (This used to be commit 68ad7b91999216e5721207b5a79c3a66be7cf420)
1997-10-27change the default file permissions on the SHARE_MEM_FILE* toAndrew Tridgell1-3/+3
0644. smbstatus now gets only read permission on the share files and does no locking. also get rid of some unnecessary umask(0) calls. smbd always runs with umask(0) (This used to be commit c6ac10170dbba57dfebc54c50d79cb29d13bb442)
1997-10-20a major share modes reorganisation.Andrew Tridgell1-1407/+51
The shares modes code is now split into separate files. The shared memory implementation is in locking_shm.c. The slow implementation is in locking_slow.c It is all controlled by a struct share_ops structure that has function pointers to the implementation of all the functions needed by a share modes implementation. An initialisation function sets up this structure. This will make adding new implementations easy and clean. This also allowed me to get rid of the ugly code in smbstatus. Now status.c links to the locking code and calls methods in share_ops. I also renamed some things and generally organised things in a much cleaner fashion. Defines and structures specific to each implementation have been moved to the appropriate file and out of smb.h. (This used to be commit 65ab9adaa0d356b8041ed8a507ea52117f2a284e)
