* Ken McDonell from SGI was interested in adding some profilingAndrew Tridgell1999-04-011-4/+0
| | | | | | | | | | | | capabilities to Samba so that Samba could talk to the SGI PCP (Performance Co-Pilot) apps. This change adds a profiling shared memory area and uses it to count two fairly trivial things, the number of uid switches and the number of SMB packets processes. To add more just edit include/profile.h and then increment it at the right place. I've also added a -P switch to smbstatus to dump the profile area.
* Changes to test in configure if capabilities are enabled on a system.Jeremy Allison1998-09-281-5/+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.
* - zero shared memory before freeing itAndrew Tridgell1998-08-301-5/+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.
* configure: Changes for extra headers.Jeremy Allison1998-08-151-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* First implementation of ChangeNotify - this version only checksJeremy Allison1998-08-031-9/+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.
* merge from the autoconf2 branch to the main branchAndrew Tridgell1998-07-291-10/+1

* nttrans.c: More NT SMB stuff.Jeremy Allison1998-07-021-2/+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.
* loadparm.c: Did it ! Changed defaults for 'case preserve' and 'short case ↵Jeremy Allison1998-06-051-3/+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.
* changed to use slprintf() instead of sprintf() just aboutAndrew Tridgell1998-05-111-1/+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.
* - added a check for broken RH5 include files. With the standard RH5Andrew Tridgell1998-03-221-0/+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 is *not* a big change (although it looks like one).Jeremy Allison1998-01-221-1/+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.
* a dummy change to shmem_sysv.c to try and break CVS out of a problemAndrew Tridgell1997-12-291-0/+1
| | | | with the ntdom branch
* - handle ENOSPC in shmem init.Andrew Tridgell1997-12-161-4/+6
| | | | - be a little bit more friendly about grabbing semaphores
* don't use SEM_UNDO because of ridiculously small undo limits on someAndrew Tridgell1997-11-011-1/+25
| | | | OSes. Instead add explicit checks for dead locks at startup.
* some locking code cleanupsAndrew Tridgell1997-11-011-152/+152

* damn. We need root privilages to do semaphore operations even if weAndrew Tridgell1997-10-291-28/+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.
* clean up the hash entry code a bit. Got rid of lp_shmem_hash_size()Andrew Tridgell1997-10-291-15/+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.
* fix for broken sunos4 includes (doesn't have SHM_R)Andrew Tridgell1997-10-281-0/+4

* SYSV IPC implementation of fast share modes.Andrew Tridgell1997-10-281-0/+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.
