* Added the hard code :-).Jeremy Allison2000-04-252-77/+453
| | | | | | | | | | HEAD should now map brl locks correctly into POSIX locks, including the really nasty case of large range unlock. There is a lot of pretty ASCII art in locking/brlock.c explaining exactly how this code works. If it is unclear, please ask me. Jeremy.
* Added the code that keeps fd's open across a close if there are other fsp'sJeremy Allison2000-04-241-36/+23
| | | | | | | | | | | | | | | open on the same dev/inode pair with existing POSIX locks. This is done at the smbd/open layer, so smbd just calls fd_close() and the transfer of any open fd's is done under the covers of fd_close(). When an fsp is closed and no other fsp's open on the same dev/inode pair have existing POSIX locks then all fd's associated with this fsp are closed. Now only the hard part of doing the POSIX range unlock code when read locks overlap remains for full POSIX/SMB lock integration.... Jeremy.
* fixed a locking database bug - it was actually harmless except thatAndrew Tridgell2000-04-231-2/+10

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | new open mechanism Andrew & I discussed. config.sub: configure: Included the QNX patch. include/vfs.h: smbd/vfs-wrap.c: smbd/vfs.c: Added ftruncate vfs call (needed). Note that we will also need locking calls in the vfs (to be added). lib/util_unistr.c: nmbd/nmbd_processlogon.c: Fix for NT domain logons causing nmbd to core dump. Also fix for sidsize DOS bug. locking/locking.c: Check value of ret before using it for memdup. printing/printing.c: Convert print_fsp_open to return an allocated fsp. rpc_server/srv_lsa.c: Fix for NT domain logons. I have removed all use of lp_share_modes() from the code (although I left the parameter in the table for backwards compatibility). It no longer makes sense for this to exist. smbd/close.c: Removed lp_share_modes(). smbd/fileio.c: Fixed parameters to unlock_share_entry call in panic code. smbd/files.c: Correctly set the unix_ERR_code to ERRnofids on fsp allocation fail. smbd/nttrans.c: smbd/reply.c: smbd/trans2.c: Changed all occurrences of open_file_shared/open_directory/ open_file_stat to return an fsp from the call. smbd/open.c: Changed all occurrences of open_file_shared/open_directory/ open_file_stat to return an fsp from the call. In addition I have fixed a long standing race condition in the deny mode processing w.r.t. two smbd's creating a file. Andrew, please note that your original idea of using open with O_EXCL in this case would not work (I went over the races very carefully) and so we must re-check deny modes *after* the open() call returns. This is because there is a race between the open with O_EXCL and the lock of the share mode entry. Imagine the case where the first smbd does the open with O_EXCL and a deny mode of DENY_ALL, but is pre-empted before it locks the share modes and creates the deny mode entry for DENY_ALL. A second smbd could then come in with O_RDONLY and a deny mode of DENY_NONE and the two opens would be allowed. The *only* way to fix this race is to lock the share modes after the open and then do the deny mode checks *after* this lock in the case where the file did not originally exist. This code will need extensive testing but seems to initially work. Jeremy.
* locking/locking.c: Fixed placeholder code for POSIX locking.Jeremy Allison2000-04-181-17/+49
| | | | | | | | printing/printing.c: Cast tdb_delete to (tdb_traverse_func) to stop warning. tmpfile gives mirror warning. smbd/groupname.c: Remember to file_lines_free() on exit. tdb/tdb.h: Add tdb_traverse_func typedef. Jeremy
* Typo - missing '}'.Jeremy Allison2000-04-131-0/+1
| | | | Jeremy.
* Removed "ole locking compat" parameter (no longer used).Jeremy Allison2000-04-121-18/+113
| | | | | | We now get/set/check POSIX locks, but I still need to code up the close fd braindamage... Jeremy.
* Implmented mapping of lock offset/count from 64 bit MS rangesJeremy Allison2000-04-121-13/+157
| | | | | | to either 63 or 31 bit POSIX ranges. Code to get these locks not yet added. Jeremy.
* Code to map tdb locks onto POSIX. Mainly placeholder code at the moment,Jeremy Allison2000-04-121-9/+157
| | | | | | but the structure is done enough so that Andrew can look it over and give a yea/nay decision. Jeremy.
* include/byteorder.h: ALIGN4/ALIGN2 macros.Jeremy Allison2000-04-111-3/+3
| | | | | | | | | | | | include/includes.h: Added SMB_BIG_UINT_BITS. lib/util.c: Removed align2/align4 - use macros. libsmb/namequery.c: Use ALIGN2. locking/locking.c: Replace do_lock, do_unlock, args with SMB_BIG_UINT, not SMB_OFF_T. Needed to move to hiding POSIX locks at a lower layer. nmbd/nmbd_processlogon.c: Use ALIGN2/ALIGN4 macros. smbd/blocking.c: Replace do_lock, do_unlock, args with SMB_BIG_UINT, not SMB_OFF_T. smbd/reply.c: Replace do_lock, do_unlock, args with SMB_BIG_UINT, not SMB_OFF_T. Jeremy.
* the first of a bunch of changes to code with getting rid of the fd_ptrAndrew Tridgell2000-04-101-6/+23
| | | | | | element in the fsp pretty mechanical stuff, but it affects lots of files.
* Fixed compile warning in locking.c:traverse_fn()Tim Potter2000-02-071-1/+2

* 1) added void* state argument to tdb_traverse. guess what! there wereLuke Leighton2000-02-042-15/+10
| | | | | | | | | | | | | | | | | | two places i found where it was appropriate to _use_ that third argument, in locking.c and brlock.c! there was a static traverse_function and i removed the static variable, typecast it to a void*, passed it to tdb_traverse and re-cast it back to the traverse_function inside the tdb_traverse function. this makes the use of tdb_traverse() reentrant, which is never going to happen, i know, i just don't like to see statics lying about when there's no need for them. as i had to do in samba-tng, all uses of tdb_traverse modified to take the new void* state argument. 2) disabled rpcclient: referring people to use SAMBA_TNG rpcclient. i don't know how the other samba team members would react if i deleted rpcclient from cvs main. damn, that code's so old, it's unreal. 20 rpcclient commands, instead of about 70 in SAMBA_TNG.
* added code to allow traversal of the byte range lock databaseAndrew Tridgell2000-01-162-3/+43
| | | | this is used with "smbstatus -B" to dump the lock list
* damn, Solaris already has a "enum lock_type"Andrew Tridgell2000-01-142-6/+7
| | | | changed it to "enum brl_type"
* we now pass all byte range locking testsAndrew Tridgell2000-01-142-4/+72
| | | | | the last piece was to use a smb timeout slightly larger than the locking timeout in bloking locks to prevent a race
* some more work on the byte range lockingAndrew Tridgell2000-01-141-6/+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.
* the bulk of the new byte range locking coodeAndrew Tridgell2000-01-132-45/+296
| | | | it doesn't map to posix locks yet, that will come later.
* added the unexpected packet database (unexpected.tdb)Andrew Tridgell2000-01-031-1/+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 :)
* - added tdb_flags option to tdb_open()Andrew Tridgell2000-01-021-1/+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
* when no shares are returned the *shares pointer must be set to nullAndrew Tridgell1999-12-221-0/+2
|
* converted all our existing shared memory code to use a tdb databaseAndrew Tridgell1999-12-215-3670/+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
* first pass at updating head branch to be to be the same as the SAMBA_2_0 branchAndrew Tridgell1999-12-135-72/+169

* Use VFS operations for file I/O.Tim Potter1999-04-042-7/+8
|
* Ken McDonell from SGI was interested in adding some profilingAndrew Tridgell1999-04-011-4/+0
| | | | | | | | | | | | capabilities to Samba so that Samba could talk to the SGI PCP (Performance Co-Pilot) apps. This change adds a profiling shared memory area and uses it to count two fairly trivial things, the number of uid switches and the number of SMB packets processes. To add more just edit include/profile.h and then increment it at the right place. I've also added a -P switch to smbstatus to dump the profile area.
* Makefile.in: Added maintainer mode fixes.Jeremy Allison1998-11-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | aclocal.m4: Added AC_LIBTESTFUNC. configure.in: Fixed -lsecurity -lsec problems. client.c: dos_ fixes. groupdb/aliasunix.c: Dead code removal. include/includes.h: Added default PRINTCAP_NAME. lib/genrand.c: dos_ fixes. lib/replace.c: Added strtoul. lib/system.c: dos_ fixes. lib/util.c: dos_ fixes. lib/util_sid.c: Signed/unsigned fixes. lib/util_str.c: removed bad const. locking/locking_slow.c: dos_ fixes. printing/printing.c: dos_ fixes. rpc_server/srv_samr.c: Dead code removal. rpc_server/srv_sid.c: global_myworkgroup defined with wrong size AGAIN ! smbd/dir.c: dos_ fixes. smbd/open.c: dos_ fixes. smbd/oplock.c: dos_ fixes. smbd/reply.c smbd/server.c smbd/service.c smbd/uid.c: dos_ fixes. Jeremy.
* Added the same open()/fopen()/creat()/mmap() -> sys_XXX calls.Jeremy Allison1998-11-172-8/+7
| | | | | | | | | | Tidied up some of the mess (no other word for it). Still doesn't compile cleanly. There are calls with incorrect parameters that don't seem to be doing the right thing. This code still needs surgery :-(. Jeremy.
* don't core dump in smbstatus if we can't open the shmem systemAndrew Tridgell1998-10-311-0/+1
|
* Reasonably large change to give us *exactly* correct NT delete on close ↵Jeremy Allison1998-10-233-31/+102
| | | | | | | | | | | | | | 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.
* Fixed sys_lseek and seek_file calls so all returnsJeremy Allison1998-10-181-172/+242
| | | | | are *checked* :-). Jeremy.
* Small tidyups for gcc in 'preen' mode....Jeremy Allison1998-10-171-2/+2
| | | | Jeremy.
* Changes to test in configure if capabilities are enabled on a system.Jeremy Allison1998-09-283-13/+6
| | | | | | | | | | Changes to get Samba to compile cleanly with the IRIX compiler with the options : -fullwarn -woff 1209,1174 (the -woff options are to turn off warnings about unused function parameters and controlling loop expressions being constants). Split prototype generation as we hit a limit in IRIX nawk. Removed "." code in smbd/filename.c (yet again :-). Jeremy.
* automated generation of .dummy files for each subdirectory;Alexandre Oliva1998-09-281-1/+0
| | | | | dummy.in files are no longer needed, and new directories will be taken care of automatically, at configure (or config.status --recheck) time
* major autoconf clean-upAlexandre Oliva1998-09-211-0/+1
| | | | fix problems in builds with srcdir!=builddir
* Added ssize_t to configure code.Jeremy Allison1998-09-111-70/+1
| | | | | | | | | | | Got 'religion' about using size_t and ssize_t for read/write stuff as part of the code to expose 64 bits to the client. This checkin does all the 'easy' stuff - such as all the read/write/lock calls - but now comes the harder parts (open & friends) and all the file enquiry functions..... Jeremy.
* ahh, the joy of deleting large chunks of code that someone else hasAndrew Tridgell1998-09-052-35/+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 :)
* tridge the destroyer returns!Andrew Tridgell1998-09-051-5/+6
| | | | | | | | | | | | | | | | | | | | | | prompted by the interpret_security() dead code that Jean-Francois pointed out I added a make target "finddead" that finds potentially dead (ie. unused) code. It spat out 304 function names ... I went through these are deleted many of them, making others static (finddead also reports functions that are used only in the local file). in doing this I have almost certainly deleted some useful code. I may have even prevented compilation with some compile options. I apologise. I decided it was better to get rid of this code now and add back the one or two functions that are needed than to keep all this baggage. So, if I have done a bit too much "destroying" then let me know. Keep the swearing to a minimum :) One bit I didn't do is the ubibt code. Chris, can you look at that? Heaps of unused functions there. Can they be made static?
* Modified dev_t and ino_t code to be 64 bit clean (including changesJeremy Allison1998-09-042-31/+118
| | | | | | | | | | to oplock break message passing). I think that smbd/nmbd are now inode and offset size independent (at least for 32 bit and 64 bit systems). Now to expose all this new functionality to NT clients..... Jeremy.
* More 64 bit stuff - now the fcntl locks are 64 bit clean.Jeremy Allison1998-09-043-23/+32
| | | | | | Nearly at the stage where I can expose the 64-bit-ness to the NT clients.... Jeremy.
* Ok - this is the 64 bit widening check in. It changes the configureJeremy Allison1998-09-032-52/+79
| | | | | | | | | | | | | | | | | | | | | | | | | to check for stat64 and friends, and then changes much of Samba to use the data type SMB_OFF_T for file size information. stat/fstat/lstat/lseek/ftruncate have now become sys_stat etc. to hide the 64 bit calls if needed. Note that this still does not expose 64 bit functionality to the client, as the changes to the reply_xxx smb's are not yet done. This code change should make these changes possible. Still to do before full 64 bit-ness to the client: fcntl lock code. statfs code widening of dev_t and ino_t (now possible due to SMB_DEV_T and SMB_OFF_T types being in place). Let me know if wierd things happen after this check-in and I'll fix them :-). Jeremy.
* More abstraction of file system data types, to move to a 64Jeremy Allison1998-09-011-4/+4
| | | | | | | | | | | | | | | | | | | | | bit file interface for the NT SMB's. Created a new define, SMB_STRUCT_STAT that currently is defined to be struct stat - this wil change to a user defined type containing 64 bit info when the correct wrappers are written for 64 bit stat(), fstat() and lstat() calls. Also changed all sys_xxxx() calls that were previously just wrappers to the same call prefixed by a dos_to_unix() call into dos_xxxx() calls. This makes it explicit when a pathname translation is being done, and when it is not. Now, all sys_xxx() calls are meant to be wrappers to mask OS differences, and not silently converting filenames on the fly. Jeremy.
* configure.in, configure: include/config.h.in: Added stropts and poll.Jeremy Allison1998-08-313-22/+24
| | | | | | | | | | | 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.
* - zero shared memory before freeing itAndrew Tridgell1998-08-302-6/+8
| | | | | | - changed the hash size to 13 (much smaller than before). This should make for more efficient shared memory usage as it will lead to less fragmentation.
* Turning on blocking locking code. NB. Blocking lock requests that are notJeremy Allison1998-08-201-0/+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.
* Makefile.in: Moved blocking lock code into smbd/blocking.c for link purposes.Jeremy Allison1998-08-191-290/+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.
* smbd/nttrans.c: Fixed bug in split off pipe code.Jeremy Allison1998-08-171-4/+12
| | | | | locking/locking.c: More blocking lock changes. Jeremy.
* much cleaner chain pointer handling for both files and pipes.Andrew Tridgell1998-08-171-7/+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.
* fixed some bugs in the locking_slow code caused by the recent changes.Andrew Tridgell1998-08-161-8/+9
| | | | | also fixed a couple of %s/%d bugs in locking slow that have been there for a while but are now revealed by the gcc printf argument testing.
* server.c: fixed a bug in close_file() with the new files.c handling codeAndrew Tridgell1998-08-161-2/+0
| | | | | bitmap.c: added bitmap hanlding code in preparation for increasing the default max open files to several thousand
* this checkin gets rid of the global Files[] array and makes it localAndrew Tridgell1998-08-153-87/+75
| | | | | | | in files.c it should now be faily easy to expand the default MAX_OPEN_FILES to many thousands.
