1998-10-23Reasonably large change to give us *exactly* correct NT delete on close ↵Jeremy Allison1-11/+18
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)
1998-09-28Changes to test in configure if capabilities are enabled on a system.Jeremy Allison1-6/+0
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. (This used to be commit e0567433bd72aec17bf5a54cc292701095d25f09)
1998-09-11Added ssize_t to configure code.Jeremy Allison1-70/+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. (This used to be commit 36544fe5476f7770bd5748574fc54be7b3ee4d4a)
1998-09-04Modified dev_t and ino_t code to be 64 bit clean (including changesJeremy Allison1-28/+103
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)
1998-08-31configure.in, configure: include/config.h.in: Added stropts and poll.Jeremy Allison1-12/+12
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)
1998-08-15this checkin gets rid of the global Files[] array and makes it localAndrew Tridgell1-20/+18
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 Tridgell1-9/+11
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)
1998-08-11include/smb.h: Removed dir_ptr. Not needed.Jeremy Allison1-6/+6
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 Allison1-6/+6
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 Tridgell1-3/+6
(This used to be commit 3bda7ac417107a7b01d91805ca71c4330657ed21)
1998-05-12This is a security audit change of the main source.Jeremy Allison1-1/+1
It removed all ocurrences of the following functions : sprintf strcpy strcat The replacements are slprintf, safe_strcpy and safe_strcat. It should not be possible to use code in Samba that uses sprintf, strcpy or strcat, only the safe_equivalents. Once Andrew has fixed the slprintf implementation then this code will be moved back to the 1.9.18 code stream. Jeremy. (This used to be commit 2d774454005f0b54e5684cf618da7060594dfcbb)
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)
1997-12-04don't use free and alloc as structure elementsAndrew Tridgell1-13/+13
(This used to be commit f7066355b00a169423b4f64f58567e19b52abc1b)
1997-11-29don't display locks for dead processes in smbstatusAndrew Tridgell1-3/+5
(This used to be commit c7df484ef6d746fb1f5b53007ee04fa54e5f2223)
1997-11-01some locking code cleanupsAndrew Tridgell1-76/+60
(This used to be commit 6d77311d6cecabafb86c02e26b30724425ef6208)
1997-10-31change from * to ^ in hashing of device/inode. Using * meant that ifAndrew Tridgell1-1/+1
the device number happened to divide the number of hash buckets we would only use a small fraction of the hash buckets, which would slow things down. (This used to be commit 623ffd701f2f966875d396d8b2df74f0cf874cda)
1997-10-31- cleanup some warningsAndrew Tridgell1-2/+0
- redo the prototypes (This used to be commit 31dcb51e05914d49d81a3faef354aaf0ab9fa63f)
1997-10-29clean up the hash entry code a bit. Got rid of lp_shmem_hash_size()Andrew Tridgell1-47/+4
and made it private to the 2 shmem implementations. Added new shmops->hash_size() function. Added code to handle the IPC system limits by looping decreasing the size of the resources (semaphores and shared memory) that we request until we get under the system limits, which can be quite low on some systems! Added checks that the creator of the IPC objects is root. Otherwise we would be open to a security hole where someone pre-creates the shared memory segment and attaches. (This used to be commit 6b6f624b63137d4750200e8cb4961b1402513632)
1997-10-28lower the default hash size if SEMMSL isn't definedAndrew Tridgell1-0/+5
(This used to be commit 9f0be847fdbcf0f8bbd69de6cdf277ae0440bcda)
1997-10-28SYSV IPC implementation of fast share modes.Andrew Tridgell1-49/+57
It will try sysv IPC first, then if that fails it will try mmap(), then after that it will try share files. I have defined USE_SYSV_IPC for Linux, Solaris and HPUX at the moment. Probably a lot more could have it defined. In fact, the vast majority of systems support it. Need autoconf again :-) It should actually be faster than the mmap() version, and doesn't need any lock files. This means the problem of the share mem file being on a NFS drive will be gone. (This used to be commit cc8fe0f0629eea9acc39e30d8d76d5890a5b6978)
1997-10-27change the default file permissions on the SHARE_MEM_FILE* toAndrew Tridgell1-3/+8
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)
1997-10-22shared memory code cleanups (partly preparing for a possible sysVAndrew Tridgell1-16/+16
shared memory implementation) (This used to be commit 8d1993c71a5d5d32636f62ba9b9a9009ec74d730)
1997-10-20loadparm.c: Changed 'interfaces only' parameter to 'bind interfaces only'. AddedJeremy Allison1-1/+1
'dos filetimes' parameter for UTIME fix. locking_shm.c: Fixed typo (sorry Andrew :-). namepacket.c: Changed lp_interfaces_only() to lp_bind_interfaces_only(). proto.h: The usual. reply.c: Made filetime calls use new file_utime call (wrapper for sys_utime). server.c: Made filetime calls use new file_utime call (wrapper for sys_utime). system.c: Added Andrew's sanity checks to times in sys_utime(). time.c: Moved set_filetime() to server.c. Made null_mtime() global. trans2.c: Made filetime calls use new file_utime call (wrapper for sys_utime). Jeremy (jallison@whistle.com) (This used to be commit 41a1d81c112a82ad2ae1b3c4ee81051f133ce1ed)
1997-10-20a major share modes reorganisation.Andrew Tridgell1-0/+739
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)
