1998-09-28Changes to test in configure if capabilities are enabled on a system.Jeremy Allison1-2/+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. (This used to be commit e0567433bd72aec17bf5a54cc292701095d25f09)
1998-09-05ahh, the joy of deleting large chunks of code that someone else hasAndrew Tridgell1-25/+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)
1998-09-05tridge the destroyer returns!Andrew Tridgell1-5/+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? (This used to be commit 2204475c87f3024ea8fd1fbd7385b2def617a46f)
1998-09-04More 64 bit stuff - now the fcntl locks are 64 bit clean.Jeremy Allison1-4/+4
Nearly at the stage where I can expose the 64-bit-ness to the NT clients.... Jeremy. (This used to be commit 422f1dd45074c0e28203aca5952e57bbe56676b6)
1998-09-03Ok - this is the 64 bit widening check in. It changes the configureJeremy Allison1-33/+60
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. (This used to be commit 14500936c321d15995c963766aac67bf1f4e3824)
1998-08-30- zero shared memory before freeing itAndrew Tridgell1-1/+4
- 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. (This used to be commit 9c1e4c2dae6323c9a1bd74148d0b45aac61e7c0a)
1998-08-15configure: Changes for extra headers.Jeremy Allison1-6/+9
configure.in: Source for header changes. client/clitar.c: Fixed isXXX macros & debugs for gcc pedantic compile. include/config.h.in: Added MEMSET, BZERO, MEMORY, RPCSVC_YPCLNT, STRINGS headers. include/includes.h: Headers for the above. include/smb.h: Made SIGNAL_CAST POSIX by default void (*)(int). lib/access.c: Fixed isXXX macros & debugs for gcc pedantic compile. lib/charset.c: Fixed isXXX macros & debugs for gcc pedantic compile. lib/debug.c: Fixed signal functs. lib/kanji.c: Fixed isXXX macros & debugs for gcc pedantic compile. lib/smbrun.c: Fixed isXXX macros & debugs for gcc pedantic compile. lib/util.c: Fixed isXXX macros & debugs for gcc pedantic compile. libsmb/namequery.c: Fixed isXXX macros & debugs for gcc pedantic compile. locking/shmem.c: Fixed isXXX macros & debugs for gcc pedantic compile. locking/shmem_sysv.c: Fixed error messages in sysV stuff. nmbd/asyncdns.c: Fixed signal functs. nmbd/nmbd.c: Fixed isXXX macros & debugs for gcc pedantic compile. passdb/passdb.c: Fixed isXXX macros & debugs for gcc pedantic compile. passdb/smbpassfile.c: Fixed isXXX macros & debugs for gcc pedantic compile. smbd/chgpasswd.c: Fixed isXXX macros & debugs for gcc pedantic compile. smbd/ipc.c: Fixed isXXX macros & debugs for gcc pedantic compile. smbd/nttrans.c: Fixed fsp code path. smbd/password.c: fixed HAVE_YP_GET_DEFAULT_DOMAIN problem. smbd/printing.c: Fixed isXXX macros & debugs for gcc pedantic compile. smbd/reply.c: Fixed isXXX macros & debugs for gcc pedantic compile. smbd/server.c: Fixed isXXX macros & debugs for gcc pedantic compile. smbd/trans2.c: Fixed core dump bug. smbd/uid.c: Fixed isXXX macros & debugs for gcc pedantic compile. Jeremy. (This used to be commit 1b9cbcd02e575dc0a95fa589f720df30a4acc46b)
1998-08-14this is the bug change to using connection_struct* instead of cnum.Andrew Tridgell1-1/+1
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)
1998-07-29merge from the autoconf2 branch to the main branchAndrew Tridgell1-3/+3
(This used to be commit 3bda7ac417107a7b01d91805ca71c4330657ed21)
1998-05-12This is a security audit change of the main source.Jeremy Allison1-3/+3
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)
1998-03-22- added a check for broken RH5 include files. With the standard RH5Andrew Tridgell1-0/+6
includes (ie. unpatched RH5) Samba gets file corruption because of the incorrect definition of the shmid_ds structure. Updating your RH5 installation of glibc-devel fixes this. - don't try to fcntl_lock() a read-only fd in shmem.c - allow level 0 debug messages to get through in smbstatus (This used to be commit 45553771f90087a12db0153524146d42155d1d3f)
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)
1997-11-01some locking code cleanupsAndrew Tridgell1-10/+10
(This used to be commit 6d77311d6cecabafb86c02e26b30724425ef6208)
1997-10-29clean up the hash entry code a bit. Got rid of lp_shmem_hash_size()Andrew Tridgell1-19/+29
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)
1997-10-28SYSV IPC implementation of fast share modes.Andrew Tridgell1-257/+274
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 Tridgell1-21/+34
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 Tridgell1-27/+17
shared memory implementation) (This used to be commit 8d1993c71a5d5d32636f62ba9b9a9009ec74d730)
1997-09-15- change a lot of occurances of errno to use strerror(errno). We can'tAndrew Tridgell1-15/+15
assume all our users are programmers :-) - automatically create the smbpasswd file if it doesn't exist when running smbpasswd. (This used to be commit 1d2361bd2dec35bce029699f54c6a61fa739fa4b)
1997-08-28added a new type to mkproto.awk so it can handle shmem.cAndrew Tridgell1-1/+1
in general if you add a new type that is returned by a non-static function then just add it to the list of known types in mkproto.awk (This used to be commit 1d4ce07435f3d6dac41a2616a044bcd441dbaced)
1997-07-24Makefile: Added UNIXWARE 2.x with shadow passwords from fja@extratech.comSamba Release Account1-2/+2

1996-10-04- changed the umask handling. We now set the umask to 0 and explicitlyAndrew Tridgell1-5/+1
set the mode on all created files. I think this is a better policy. - change the debug levels on some items - fix a charset handling bug which affected foreign and extended charset users - no longer switch back to the original directory when idle, instead switch to / as the original directory may not be readable by ordinary users. - fix some bugs where the create mode of files was not being explicitly set (it was relying on the umask and using fopen). Not a big bug as it only affected obscure commands like the messaging ops. - got rid of the lock code in the lpq cache as its no longer needed - rewrote smbrun to be faster and to remove the security hole. We now don't actually need a external smbrun binary, its all done by smbd. - add a more explicit warning about uids and gids of -1 or 65535 (This used to be commit 5aa735c940ccdb6acae5f28449d484181c912e49)
1996-08-17- made FAST_SHARE_MODES standard for LinuxAndrew Tridgell1-2/+3
- you can now press enter after a password prompt with "smbclient -L hostname" and it will use a blank username and password, the same as if you used -U% - changed the wins.dat store code to not go via a string variable (just use fprintf instead) - removed a "unsigned long" that luke put back in, changing it to uint32 to keep 64 bit machines happy. Naughtly luke! - allow guest non-connnected print queue listings so ms client 3 can work (This used to be commit 917160dee69bbc198985b6f3232ca2dcda809d8a)
1996-08-15- added FAST_SHARE_MODES codeAndrew Tridgell1-0/+722
