2000-05-02Added sys_fork() and sys_getpid() functions to stop the overheadJeremy Allison1-1/+1
of doing a system call every time we want to just get our pid. Jeremy. (This used to be commit 148628b616b5c29ba6340d65fc3ddbcabba6e67a)
2000-04-24Now that fsp's are created on successful file open, the structure memberJeremy Allison1-10/+23
fsp->open is no longer needed (if an fsp pointer is valid, then it's open :-). NB for Luke, this patch also did not apply to TNG. TNG is not yet identical w.r.t file serving with HEAD. This makes it impossible for me to help maintain TNG. Please fix asap. lib/substitute.c: Removed unused variable (pidstr). Jeremy. (This used to be commit 389b700a26e8a308a0dff6fc038c38068aa0119a)
2000-04-22This is a *big* checkin that may break some things, but implements theJeremy Allison1-1/+7
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. (This used to be commit ab0ecc39d688f16b9692fe90b991f0b89287070a)
2000-04-10initialise fsp->fd to -1Andrew Tridgell1-0/+1
(This used to be commit 5257ff5d67632922a64266ad2ce5d5a38c701cbc)
2000-04-10the bulk of the changes to get rid of fd_ptr and move print openAndrew Tridgell1-106/+12
handling to printing/printing.c most of this was just replacing things like fsp->fd_ptr->fd with fsp->fd the changes in open.c are quite dramatic. Most of it is removing all the functions that handled the fd multiplexing (This used to be commit d1827a3648009fd0a0d165055015d9aeda7a1037)
2000-02-03Mega-VFS merge. Yeah baby!Tim Potter1-1/+1
Synopsis: change every disk access function to work through a vfs_ops structure contained in the connection_struct. (This used to be commit 3aad500c0fb61232ed3431ff4b743b5d18ec852f)
2000-01-16use string_set() instead of string_init()Andrew Tridgell1-1/+1
bug pointed out by Richard (This used to be commit 070f49397ff24e4d6ba7c2c1cfaef2dfa0944bd0)
1999-12-13first pass at updating head branch to be to be the same as the SAMBA_2_0 branchAndrew Tridgell1-12/+6
(This used to be commit 453a822a76780063dff23526c35408866d0c0154)

1999-04-20Changed arguments to fsync() function to break dependency onTim Potter1-2/+3
connection_struct. (This used to be commit ee6f826ccc0897a4538f6f9a560127c54a4c4038)
1999-04-04Use VFS operations for file I/O.Tim Potter1-3/+2
(This used to be commit cfddbdb62485256a947a30e04c753200451cbe1c)
1998-11-18Fixed crash bug which was assuming that fd_ptr was always non-nullJeremy Allison1-2/+5
(which is not the case with open directories). Jeremy. (This used to be commit c154b1601f5891d664fc538ec8874fa8ef2061e6)
1998-10-23Reasonably large change to give us *exactly* correct NT delete on close ↵Jeremy Allison1-0/+35
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)
1998-10-16Re-added code to tell the user how many open files theyJeremy Allison1-5/+15
have. Needed for server diagnosis purposes... Jeremy. (This used to be commit 04d79a9ae515e7259277f9980552f1d61df239f1)
1998-10-08- fixed a bunch of warnings and minor errorsAndrew Tridgell1-1/+1
- got smbtorture to compile - removed %D from some of lukes code - Luke, what is %D? it ain't portable anyway (This used to be commit 91597c12fb593f49b23c7cea5b64dbb89a0428b3)
1998-10-05added a function set_maxfiles() to set our file rlimit to the maxAndrew Tridgell1-27/+8
possible and return the max. (This used to be commit 7a7b5ee1689b6be57752d176c7b77a2f1b453486)
1998-10-01got rid of USE_FILES_ARRAY code (it was unused)Andrew Tridgell1-106/+4
(This used to be commit f15ece53162304d855bea4f329f3faed8813a831)
1998-09-30(Finally) implemented "max open files" as a global smb.conf parameter.Jeremy Allison1-22/+44
Sets up the files array correctly - limited by the smb.conf parameter and by the max fd's per process as found by getrlimit(). Jeremy. (This used to be commit eca24bd24352c688cdf48c1ef14adb8ac353468f)
1998-09-23First cut at kernel oplocks. This should have no effect unless runninJeremy Allison1-13/+15
on a machine that supports them in autoconf. Move various functions out of lib/util.c into smbd/process.c and smbd/oplock.c where they belong. Jeremy. (This used to be commit c3c5e13f85c97939746070132dad941e79c546fb)
1998-09-10smb.h: Removed fdnum from file_fd_struct. Not needed.Jeremy Allison1-29/+109
files.c: Removed fd bitmap - not needed. Added code to do use arrays rather than linked list - disabled by default but can be enabled to check performance. Jeremy. (This used to be commit 069efc04545d5fdfc5c40467b8b7554ed5226a2e)
1998-09-05some cleanups to use ZERO_STRUCT() and friendsAndrew Tridgell1-4/+4
(This used to be commit 7b154dc4313324dfad6cf0117b8ce246bf12bf16)
1998-09-05tridge the destroyer returns!Andrew Tridgell1-2/+3
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? (This used to be commit 2204475c87f3024ea8fd1fbd7385b2def617a46f)
1998-09-05Bugfix for leak in reference counted file struct.Jeremy Allison1-3/+3
Added "nt smb support" parameter to allow NT SMB's to be turned off. Jeremy. (This used to be commit 63f65f5027d5022153fa2757b49c56829db1725b)
1998-09-04Modified dev_t and ino_t code to be 64 bit clean (including changesJeremy Allison1-1/+7
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. (This used to be commit 5910d07bbf45a34d3c901461f74704c029a79474)
1998-09-01More abstraction of file system data types, to move to a 64Jeremy Allison1-1/+1
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. (This used to be commit 28aa182dbffaa4ffd86047e608400de4b26e80eb)
1998-08-31configure.in, configure: include/config.h.in: Added stropts and poll.Jeremy Allison1-5/+5
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 Allison1-2/+2
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)
1998-08-17Fixed bug introduced by the recent changes where the chain_fnumJeremy Allison1-1/+19
could be overwritten in oplock processing code. Jeremy. (This used to be commit 908a583b48e37c5e869216f4dc92d4a587ff1238)
1998-08-17added some optimisation for the case where the number of open files isAndrew Tridgell1-33/+14
very large. files.c now promotes a files_struct to the top of the list if it is used when it is more than 10 elements from the top. also moved common linked list code for the 5 sets of linked lists that I've created over the past few days into dlinklist.h (I've explained to Chris why I didn't use the ubiqx code) (This used to be commit 1eb9ae2996b5a243a147f485e7e353d54f820852)
1998-08-17moved connection_struct handling code into smbd/conn.c and changed itAndrew Tridgell1-8/+12
to a linked list with bitmap format. (This used to be commit b7aaab1b6b2d2f72b2bb7c11f5c7bf081a6093d9)
1998-08-17much cleaner chain pointer handling for both files and pipes.Andrew Tridgell1-15/+40
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)
1998-08-17some cleanups from the conversion of Pipes[] to a linked list. I alsoAndrew Tridgell1-11/+8
removed most cases where a pnum is used and substituted a pipes_struct*. in files.c I added a offset of 0x1000 to all file handles on the wire. This makes it much less likely that bad parsing will give us the wrong field. (This used to be commit 8bc2627ff28d340db65bfa017daca2dc291d5ef7)
1998-08-16- some tidying up in files.cAndrew Tridgell1-3/+3
- handle null fsp in DEBUG() at end of reply_ntcreate_and_X(). Jeremy, can you fix this properly? - get snum right in print queue code in ipc.c (it was broken by my connections_struct changes). (This used to be commit b3dd3785751db2d5d0a80ffac9c3df01c9909891)
1998-08-16got rid of the Files[] array completely (previously I'd just made itAndrew Tridgell1-146/+207
private to files.c) It now is a doubly linked list with a bitmap for allocated file numbers. Similarly for the fd_ptr code. I also changed the default maximum number of open files to 4096. The static cost is 1 bit per file. It all seems to work, and it passes the "does Sue scream" test, but if you see weird behaviour then please investigate. With the volume of new code that has gone in there are bound to be one or two bugs lurking. note that you must do a "make clean" before building this as many data structures have changed in size. (This used to be commit 79755ce97004b787d7e83a8d18fc4c7c003b7231)
1998-08-16changed find_free_file() to file_new().Andrew Tridgell1-1/+1
(This used to be commit 3daee29636dcb2d99a0e7c08179a098befae00dc)
1998-08-15this checkin gets rid of the global Files[] array and makes it localAndrew Tridgell1-0/+321
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)
