2002-12-03Fixed nasty bug where file writes with start offsets in the rangeJeremy Allison1-8/+8
0x80000000 -> 0xFFFFFFFF would fail as they were being cast from IVAL (uint32) to SMB_OFF_T (off_t or off64_t, both *signed* types). The sign extension would cause the offset to be treated as negative. Thanks to Herb for helping me track this one down (IRIX is good for large file tests :-). Jeremy. PS. That horrid EXEXIST thing has broken configure..... (This used to be commit 2d14c442bc601a277458b69f05a763aa2a1ab3b7)

2002-03-13include/smb_macros.h: Don't round up an allocation if the size is zero.Jeremy Allison1-3/+3
"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)

2001-08-30this was a stupid typo,Simo Sorce1-1/+1
thanks to Jochen Dolze (dolze@epcnet.de) for pointing out. (This used to be commit a554d5a99a03e6e8df7e946e5636f5ee80b21969)
2001-08-27started converting NTSTATUS to be a structure on systems with gcc in order ↵Andrew Tridgell1-4/+4
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 Tridgell1-243/+231
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)
2001-07-02Fixed the nastiest locking bug to track down.... smb_pids are sent in theJeremy Allison1-4/+8
lockingX calls - use that instead of smb_pid in the packet. Jeremy. (This used to be commit a3925cb9c6303ce24e5fecad6c8f3a0ba78b9ee0)
2001-06-21next_token() was supposed to be a reentrant replacement for strtok(),Andrew Tridgell1-3/+6
but the code suffered from bitrot and is not now reentrant. That means we can get bizarre behaviour i've fixed this by making next_token() reentrant and creating a next_token_nr() that is a small non-reentrant wrapper for those lumps of code (mostly smbclient) that have come to rely on the non-reentrant behaviour (This used to be commit 674ee2f1d12b0afc164a9e9072758fd1c5e54df7)

2001-03-11Merge of new 2.2 code into HEAD (Gerald I hate you :-) :-). Allows new SAMRJeremy Allison1-4/+0
RPC code to merge with new passdb code. Currently rpcclient doesn't compile. I'm working on it... Jeremy. (This used to be commit 0be41d5158ea4e645e93e8cd30617c038416e549)
2000-05-10more merging voodooAndrew Tridgell1-0/+4
this adds "#define OLD_NTDOMAIN 1" in lots of places. Don't panic - this isn't permanent, it should go after another few merge steps have been done (This used to be commit 92109d7b3c06f240452d39f669ecb8c9c86ab610)

rpc_server/srv_pipe_hnd.c: Bring into sync with 2.0.x. smbd/blocking.c: Improve blocking debug reporting. utils/torture.c: Added check for NT locking bug. Jeremy. (This used to be commit e8ff6d3fb5537c39611a5784bf7216ae812acd27)
2000-04-11include/byteorder.h: ALIGN4/ALIGN2 macros.Jeremy Allison1-6/+6
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. (This used to be commit 491eea8a20bf80d426625479326211dc975857a6)
2000-04-11finally got sick of the "extern int Client" code and the stupidAndrew Tridgell1-3/+2
assumption that we have one socket everywhere while doing so I discovered a few bugs! 1) the clientgen session retarget code if used from smbd or nmbd would cause a crash as it called close_sockets() which closed our main socket! fixed by removing close_sockets() completely - it is unnecessary 2) the caching in client_addr() and client_name() was bogus - it could easily get fooled and give the wrong result. fixed. 3) the retarget could could recurse, allowing an easy denial of service attack on nmbd. fixed. (This used to be commit 5937ab14d222696e40a3fc6f0e6a536f2d7305d3)
2000-01-25First set of speed improvements from Ying Chen <ying@almaden.ibm.com>.Jeremy Allison1-1/+0
Inline several commonly used functions as macros. Jeremy. (This used to be commit fc0219c7cc4b83e6db17d5b3be70d74fd7971089)
2000-01-14Added "inherit permissions" patch.Jeremy Allison1-1/+7
Fixed locking bug found by Andrew. Jeremy. (This used to be commit 38dffd360dc2e44bfc9e751f017e24f81ff0f2fa)

(This used to be commit 453a822a76780063dff23526c35408866d0c0154)
1998-09-26Small update to clitar.c to omit warnings about servers notRichard Sharpe1-3/+3
letting us change the date unless tar_real_noisy is True. Also updated a few places where variables are declared but not set. (This used to be commit b46f1024c939ee9ecb8deb9c844acbd4b5f109c6)
1998-09-11Ok - this is the 'expose 64 bit to the clients' checkin.Jeremy Allison1-2/+2
I have tested it by creating a 'holey' 20GB file - checking that it shows up correctl in the NT file view (it does) and am busily copying it to NULL: on the NT box. All good so far.... :-). Also implemented NT 'delete on close' semantics. Jeremy. (This used to be commit 1654faee80648583e6a47ab7eda990fefdf85124)
1998-09-11Added ssize_t to configure code.Jeremy Allison1-13/+37
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. (This used to be commit 36544fe5476f7770bd5748574fc54be7b3ee4d4a)
1998-08-21Fixes for the problem in blocking locks with file_fsp returning theJeremy Allison1-29/+40
chain_fsp on close (if you don't know what this means, consider yourself lucky - this one took a day to track down :-). Jeremy. (This used to be commit 193cb5382464173e99a538867a266d793f0ceab5)
1998-08-20Turning on blocking locking code. NB. Blocking lock requests that are notJeremy Allison1-35/+249
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)
