1998-09-28Changes to test in configure if capabilities are enabled on a system.Jeremy Allison1-5/+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)
1998-08-30- zero shared memory before freeing itAndrew Tridgell1-5/+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)

1998-08-03First implementation of ChangeNotify - this version only checksJeremy Allison1-9/+13
for changes in the directory modify timestamps. A better version will look at the requested client flags, and create a hash that represents the current state of the directory, and check against this instead. debug.c: Added lp_timestamp_logs() function. loadparm.c: Added "change notify timeout" in seconds (default 60) - this is the scan rate for a directory. Added ""timestamp logs" boolean - default True. Turns off log timestamps (so I can read them :-). nttrans.c: ChangeNotify implementation. server.c: ChangeNotify implementation. shmem_sysv.c: Added exits on shmem errors (without them smbd can core dump if some calls fail). smb.h: Added ChangeNotify flags for future use. util.c: Tidied up typedef. Jeremy. (This used to be commit a0748c3f53974483680ebe2ea4f556ece8d7fa43)
1998-07-29merge from the autoconf2 branch to the main branchAndrew Tridgell1-10/+1
(This used to be commit 3bda7ac417107a7b01d91805ca71c4330657ed21)
1998-07-02nttrans.c: More NT SMB stuff.Jeremy Allison1-2/+9
shmem_sysv.c: Fix for shared memory problems on several systems, Second and subsequent use of shmget should use zero as the size. Fix from Veselin Terzic <vterzic@systems.DHL.COM> Jeremy. (This used to be commit 1cd94b24592ca31ffae671acfd83b0d42b212cab)
1998-06-05loadparm.c: Did it ! Changed defaults for 'case preserve' and 'short case ↵Jeremy Allison1-3/+3
preserve'. Also removed 'domain allow/deny' parameters. shmem_sysv.c: Added strerror code so I can see why sysV calls are failing. lib/rpc/server/srv_netlog.c: Removed code that used 'domain allow/deny' parameters - replaced with a comment so I will remember to fix this later. Jeremy. (This used to be commit 5f46c7c4b11a75f1ffbd806cde915b4bf28232db)
1998-05-11changed to use slprintf() instead of sprintf() just aboutAndrew Tridgell1-1/+1
everywhere. I've implemented slprintf() as a bounds checked sprintf() using mprotect() and a non-writeable page. This should prevent any sprintf based security holes. (This used to be commit ee09e9dadb69aaba5a751dd20ccc6d587d841bd6)
1998-03-22- added a check for broken RH5 include files. With the standard RH5Andrew Tridgell1-0/+9
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)
1997-12-29a dummy change to shmem_sysv.c to try and break CVS out of a problemAndrew Tridgell1-0/+1
with the ntdom branch (This used to be commit 213c3a4ed27cdc689e941b9a6d70e02e8b7dedd4)
1997-12-16- handle ENOSPC in shmem init.Andrew Tridgell1-4/+6
- be a little bit more friendly about grabbing semaphores (This used to be commit 87f88708939a3b72b26716a0d6648c4ea2d14047)
1997-11-01don't use SEM_UNDO because of ridiculously small undo limits on someAndrew Tridgell1-1/+25
OSes. Instead add explicit checks for dead locks at startup. (This used to be commit 79858d610c37675b9dc56a949723053ac9b67620)
1997-11-01some locking code cleanupsAndrew Tridgell1-152/+152
(This used to be commit 6d77311d6cecabafb86c02e26b30724425ef6208)
1997-10-29damn. We need root privilages to do semaphore operations even if weAndrew Tridgell1-28/+43
have done the semget() as root. The problem is that become_root() and unbecome_root() are so slow! I've provided two options. The default is to set the semaphores (but _not_ the shared memory) world writeable so that a become_root() isn't needed. Otherwise you can define SECURE_SEMAPHORES and pay the performance penalty. (This used to be commit 2bbd8d2cbc5cf1901859a181bc9ec29822995e51)
1997-10-29clean up the hash entry code a bit. Got rid of lp_shmem_hash_size()Andrew Tridgell1-15/+55
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)
1997-10-28fix for broken sunos4 includes (doesn't have SHM_R)Andrew Tridgell1-0/+4
(This used to be commit 6ca96782ace2258707f49d204726a00baef9d941)
1997-10-28SYSV IPC implementation of fast share modes.Andrew Tridgell1-0/+621
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)
