ChangeLog (Nov 10 2004)


2004-09-10  Don Zickus 
OpenDLM port to the linux 2.6 kernel and cleanups based on new compiler settings
	* clm_data.h, clm_locksw.h, clm_migrate.h, clm_reconfig.h,
	* clmstructs.h, clm_client.c, clm_clmlock.c, clm_clmlock.h,
	* clm_clmunlock.c, clm_deadlock.c, clm_direct.c, clm_direct.h,
	* clm_group.c, clm_libr.c, clm_libr.h, clm_lock.c, clm_lock.h,
	* clm_locksw.c, clm_migrate.c, clm_migrate_local.h, clm_purge.c,
	* clm_purge.h, clm_resource.c, clm_resource.h, clm_scn.c,
	* clm_timeout.c, clm_tune.c, clm_unixlock.c, clm_unixlock.h, 
	* dlm_real_proto.h, dlm_recover.c 
		renaming "struct resource", allocate_resource() and 
		deallocate_resource() to "struct dlm_resource, 
		dlm_allocate_resource() and dlm_deallocate_resource().  
		This prevents a conflict with the 2.6 kernel header file 
		(ioport.h) which is included in dlm_kerndd.c and uses 
		"struct resource" and allocate_resource().  
	* api_init.c, clm_cti.c 
		setup kernel version conditional compiling for utilizing 
		tq_struct/work_struct
	* ast.h, dlm_utilites.h, kclient2_.c
		prototype cleanup (based on compiler warning)
	* clm_info.h, dlm_devmsg.h
		removed unused enum that caused compiler errors
	* dlm_kernel.h, cccp_private.h
		removed syslog.h from inclusing as it caused compiler errors and
		instead copied/pasted the relevant info (ie the bsdlog level 
		definitions).  Also prototype cleanup (based on compiler warning)
	* cccp_deliver.c, cccp_udp.c, dlm_kernel.c
		added kernel version conditional compiling for module specific 
		commands (ie MOD_INC_USE_COUNT).  Modified call to 
		dlm_daemonize() to reflect changes
	* cccp_init.c, cccp_msg.c, cccp_output.c, cccp_ports.c, cccp_proto.c, 
	* dlm_base.c, dlm_memory.c
		exported symbols for module usage.  This gives cleaner control 
		of what is used outside of the module and what is not.  
	* cccp_kernel.c
		simplified the timer initialization code
	* clm_main.c
		added kernel version conditional compiling for module specific 
		commands (ie MOD_INC_USE_COUNT).  Modified call to 
		dlm_daemonize() to reflect changes.  simplified the timer 
		initialization code.
	* clm_rldb.c, clm_rldb.h
		prototype cleanup (based on compiler warning) and renaming 
		"struct resource" to "struct dlm_resource"
	* dlm_kerndd.c
		setup kernel version conditional compiling for utilizing 
		various device filesystem.  'devfs' seems to have gone away 
		in kernel 2.6.
	* dlm_proc.c
		fixed bugs in dlm_proc_entry_destroy(), which is used to 
		remove files from the /proc filesystem.  
	* dlm_utilities.c
		exported symbols for module usage.  This gives cleaner control 
		of what is used outside of the module and what is not.  
		Modified dlm_daemonize() to control the kernel version 
		differences inside this function instead of across the system
	* kernel.mk
		added compiler flag, EXPORT_SYMTAB.  This flag utilizes the 
		EXPORT_SYMBOLS declared in all the modules know.  These symbols 
		control which symbols are allowed to be used externally or not.
	* dlm_cmdline.c
		added syslog.h include file which was removed from another dlm 
		header file
	* dlm_device.c
		added kernel version conditional compiling for "modprobe" 
		parameters.
	* dlmdk/dlmcccp/dlmkernapi/tests Makefile.am
		removed due to completely new kernel module build system for 
		the 2.6 kernel.  
	* dlmdk/dlmcccp/dlmkernapi/tests Makefile.in
		no longer generated from the Makefile.am file.  Instead 
		permanently included in the build system.  These 4 files have 
		been hacked up to support generation of a Makefile that will 
		work with either the 2.4 kernel or the 2.6 kernel based on a 
		variable defined at configure time ($NEW_KBUILD).  This file was 
		originally generated from Makefile.am then handcrafted into the 
		result it is now (not the cleanest approach).  In addition 
		because the dlmkernapi utilizes files from the api directory 
		(which is also compiled for the user space libraries), the 
		Makefile creates symbolic links to the *.c files used before 
		compiling the object files into the local directory.  
		
	**NOTE** The new Makefile system described above is NOT ideal nor the 
		preferred solution.  The proper solution (as discussed with 
		community members and referenced by other comparable projects, 
		ie alsa-sound) is to split the packages into a user space package
		and kernel space package.  Then manage them separately.  However 
		due to the api directory overlap (for both user and kernel 
		interfacing), this is a daunting task.  In addition many header 
		files overlap also causing synchronization issues.  Thus the 
		spliting of the package could take quite a bit of time and 
		careful consideration to do it properly.  Hence the quick and 
		dirty solution provided just to push this forward.

2004-09-03  Don Zickus 
OpenDLM much needed performance fixes for scalability and SMP issues.  
Also some minor cleanups
	* src/api/ast_stub.c:
		fix ASTpoll such that it only calls the kernel once per AST 
		not twice.
	* src/include/clmstructs.h:
		change max name length to 32 bytes.  Also change DBPRINTF 
		macro to perform and if-then check before processing the 
		arguments being passed to it.
	* src/include/cltrc.h:
		compile out the tracking definitions (ie TRCHKGT)
	* src/include/dlm.h:
		change max resource name length to 32 bytes
	* src/include/dlm_kernel.h:
		change the bsdlog prototype to a definition when not in use.  
		This speeds up performance.
	* src/kernel/dlmcccp/cccp_deliver.c:
		modify the message delivery subsystem.  The port locking and 
		unlocking has been removed allowing the system to improve 
		performance dramtically
	* src/kernel/dlmcccp/cccp_ports.c:
		modified the port delivery subsystem such that there is no 
		more port locking.  Instead just a single message queue and 
		a single lock protecting it.
	* src/kernel/dlmcccp/cccp_private.h:
		changed prototype for cccp_port_dequeue_message.
	* src/kernel/dlmdk/Makefile.am:
		remove DBPRINT compile option
	* src/kernel/dlmdk/ast_kern.c:
		changed ASTget to communicate more effectively with the user 
		space ASTpoll code thus saving a kernel call.  Disabled some 
		unused segment code (ie att_seg and det_seg).  Also added a 
		whole bunch of AST spinlocks for SMP purposes.  These locks 
		used to be grouped together with the LK_ENTRY locks which are 
		not functionally equivalent.
	* src/kernel/dlmdk/clm_client.c:
		modified findclientbypid() and findclient() to improve a 
		bottleneck.  The new code finds the pid a lot quicker than 
		recursing through multiple function calls.
	* src/kernel/dlmdk/clm_clmlock.c:
		remove useless call to check_handles()
	* src/kernel/dlmdk/clm_compat.c:
		compile out clm_vers_send, clm_vers_rcv, and clm_vers_reset.  
		They were useless linux stubs anyway.  
	* src/kernel/dlmdk/clm_cti.c:
		removed LK_ENTRY locks from clm_recv().  There is no critical 
		section of code here and just slows down SMP.
	* src/kernel/dlmdk/clm_libr.c:
		comment out clm_vers_send() function.
	* src/kernel/dlmdk/clm_locallock.c:
		comment out clm_vers_send() function.
	* src/kernel/dlmdk/clm_lock.c:
		compiles out check_handles()
	* src/kernel/dlmdk/clm_lock.h:
		changes check_handles() to a empty macro when not being used
	* src/kernel/dlmdk/dlm_proc.c:
		remove LK_ENTRY locks around version check
	* src/kernel/dlmdk/dlm_real_proto.h:
		changes clm_vers_snd, clm_vers_rcv, clm_vers_reset to empty 
		macros when not being used
	* src/kernel/dlmdk/dlm_utilities.c:
		compile out bsdlog when not in use
	* src/kernel/dlmdk/dlm_utilities.h:
		changes bsdlog to empty macro when not being used

2004-08-04  Don Zickus 
	* released OpenDLM 0.9.2

2004-06-30  Don Zickus 
OpenDLM configuration cleanups and ccm fixes
	* acinclude.m4:
		clean up warnings from new automake tools
	* configure.ac:
		clean up warnings from new automake tools.
	* src/user/common/dlm_ccm.c:
		added fix for a single node cluster.

2004-06-30  Don Zickus 
OpenDLM does not shutdown properly
	* src/kernel/dlmcccp/cccp_deliver.c:
		added linux specific completion routines for the 
		cccp_msg_delivery_thread when it exited
	* src/kernel/dlmcccp/cccp_init.c:
		added linux specific completion variables to use when shutting 
		down the cccp threads.  The function cccp_stop() will not exit 
		until all cccp threads have shutdown successfully.  The order 
		of the shutdown has been modified in such a way it now makes 
		sense (shut down the nodes, close the read pipe, then flush 
		the system).  
	* src/kernel/dlmcccp/cccp_udp.c:
		added linux specific completion routines for the 
		cccp_poll_thread and cccp_retransmit_thread when they exit.
	* src/kernel/dlmdk/clm_client.c:
		split kill_clients() in half.  The original intent was to kill 
		all clients and cleanup after them then remove any 
		kmem_cache_memory lying around.  Unfortunately, the dlm does 
		not shut down as simple as that.  Instead kill_clients() needs 
		to kill the clients, have another function destroy all its lock 
		elements, then call free_client() (the other half of kill_client) 
		to finish cleaning up the client stuff.
	* src/kernel/dlmdk/clm_client.h:
		add prototype for new function free_client().
	* src/kernel/dlmdk/dlm_kernel.c:
		rearrange the order in dlm_exit() such that it makes sense.  
		The idea is to shut down the DLM, flush the CCCP and hope all 
		the memory is cleaned up by the time all the 
		kmem_cache_destroy functions are called.  
	* src/kernel/dlmdk/dlm_real_prototype.h:
		add prototype for function free_client().	

2004-06-08  Stanley Wang

2004-05-01  Don Zickus 
OpenDLM cleanups needed for demo
	* src/api/api_vms.c:
		fix error path case for DLM_VALNOTVALID in clm_reqresp() and 
		removed dlm_errno race condition inside dlmlockx().  
	* src/kernel/dlmdk/clm_main.c:
		release the LK_ENTRY lock upon exiting clm_master_loop().  This 
		prevents deadlock with CCCP updon shutdown.
	* src/user/dlmdu/dlm_daemon.c:
		remove console message stating "no new cluster events" inside 
		main().	

2004-05-01  Don Zickus 
OpenDLM fixes to support up to a 4 node cluster
	* src/kernel/dlmcccp/cccp_proto.c:
		remove code added by duplicate packet fix, this was incorrectly 
		understood perviously.
	* src/kernel/dlmdk/clm_info.c:
		allow topology changes for 3 nodes and queue state machine 
		changes as opposed to nesting them.
	* src/kernel/dlmdk/clm_main.c:
		allow all state machine changes to be queued and handled 
		properly.
	* src/kernel/dlmdk/clm_msg.c:
		queue state machine changes as opposed to nesting them.  Also 
		allow all barrier messages to be invoked by handle_sync() only
	* src/kernel/dlmdk/dlm_real_proto.h:
		extern the sched_queue() function and change to function 
		parameters of new_change_request().
	* src/kernel/dlmdk/dlm_recover.c:
		queue state machine changes as opposed to nesting them.  Also 
		cleaned up a memory leak and a wrong cccp callback function
	* src/kernel/dlmdk/dlm_sched.c:
		modify how new_change_request works to allow more state machine 
		queueing
	* src/user/common/dlm_heartbeat.c:

2004-04-29   Stanley Wang 
	* src/kernel/dlmdk/dlm_recover.c:
	Fix opps in recovery process.	

2004-04-22   Stanley Wang 
	* src/kernel/dlmdk/clm_deadlock.c:
	Fix deadlock detecting bug in clmdd_decode().	

2004-04-21  Don Zickus 
OpenDLM startup scripts did not work properly
	* configure.ac:
		support building on Suse
	* admin/haDLM:
		modified startup/shutdown functionality and changed default
		configure file to be haDLM.conf to be consistent with the
		OpenDLM package and the spirit of Linux configure files
	* docs/haDLM.conf:
		new files, supports default configurations
	* docs/Makefile.am:
		add haDLM.conf

2004-04-15  Don Zickus 
OpenDLM Build string does not exist
	* src/kernel/dlmcccp/Makefile.am:
	* src/kernel/dlmdk/Makefile.am:
	* src/user/dlmdu/Makefile.am:
		added a makefile generated timestamp file that will be 
		linked into the binaries of dlmdu, dlmdk.core, dlmdk.base, 
		and cccp.   The timestamp file is dependent on the respective
		source files in the directories.  Once the binaries are 
		compiled, using the command strings, one can grep for "Date" 
		or "Time" to retrieve the build string.  This should 
		accurately reflect the last time that particular binary was 
		compiled.  NOTE:  each binary will have a different timestamp. 
	* src/kernel/dlmcccp/clm_main.c:
		changed the timestamp output to use the new dlm_timestr and 
		changed the bsdlog output to a printk such that the time stamp 
		will always be logged, not just when debugging is turned on 
		for the kernel modules.
	* src/make/kernel.mk:
		added TIMESTAMP_FILE and TIMESTAMP_STR variables to allow 
		a generic interface to the Makefile.am files
	* src/make/user.mk:
		added TIMESTAMP_FILE and TIMESTAMP_STR variables to allow
		 a generic interface to the Makefile.am files
	* src/user/dlmdu/dlm_cmdline.c:
		changed the timestamp output to use the new dlm_timestr 
		and added a syslog call to log the dlmdu timestamp to 
		/var/log/messages.

2004-04-14   Stanley Wang 
	* src/user/common/dlm_ccm.c:
	Ingnore old membership message and code cleaning.

2004-04-13   Stanley Wang 
	* src/kernel/dlmcccp/cccp_ports.c:
	Clean all pending message in destroyPorts().

2004-04-13   Stanley Wang 
	* src/user/common/dlm_ccm.c:
	Use "SA_CLM_NODE_LEFT" macro instead of integer value.

2004-04-09   Stanley Wang 
	* Makefile.am:
	* configure.ac:
	* src/user/common/Makefile.am:
	* src/user/common/dlm_ccm.c:
	* src/user/dlmdu/Makefile.am:
	Add CCM plugin for OpenDLM.

2004-04-09  Don Zickus 
OpenDLM Failover fixes
	* src/kernel/dlmdk/dlm_recover.c:
		fixed two issues in regards to the recovery process.  The 
		first one is during the RESOURCE_QUERY state, opendlm might 
		prematurely proceed to the next step without receiving an 
		answer to a directory request.  The second fix is in regards 
		to a memory leak that causes the cache memory to fail in its 
		attempt to cleanup.  The memory leak was the result of an 
		internal state machine message that was not released caused 
		by an external cccp message.  

2004-04-09  Don Zickus 
OpenDLM Stability cleanups
	* src/kernel/include/Makefile.am:
		include the header files dlm.h and dlm_cluster.h into the 
		install distribution.  They will be place in 
		/usr/include/opendlm to be used by client apps.
	* src/kernel/dlmdk/clm_group.c:
		changed an abort to a printk in the function grp_rmpid() 
		and have the function return an error instead.  There is 
		no reason for the abort, an error return code is sufficient. 
	* src/kernel/dlmdk/clm_rldb.c:
		removed an assertion statement that conflicted with how the 
		failover code works.  The old assertion can be found in the 
		function rl_update().
	* src/user/common/dlm_heartbeat.c:
		added a printf do describe the reason why opendlm would 
		fail to connect with the heartbeat module.  This aids in 
		the debugging.
	* src/user/dlmdu/dlm_device.c:
		commented out a failure return path.  The failure is the 
		result of a bug in one of the libraries when the executes 
		a 'system()' command.  The command returns a failure when 
		in fact it succeed.  Instead of failing, opendlm prints out 
		a message and then tries to open the module it supposedly 
		failed to load.  If the 'open' fails, then the modules did 
		not load, otherwise the failure was incorrect and opendlm 
		proceeds as normal.

2004-04-05  Don Zickus 
OpenDLM migration does not work	
	* src/kernel/include/dlm_list.h:
		fixed list manipulations functions by correcting 
		'empty list' cases and an initialization bug.
	* src/kernel/dlmdk/clm_migrate.c:
		fixed a struct increment bug and a kernel oops due to 
		bad resource pointer bug.  Various aesthetic cleanups.  
		
2004-04-05  Don Zickus 
OpenDLM deadlock detection does not work correctly
	* src/kernel/dlmdk/dlm_deadlock.c:
		the remote message passing parsing was broken, so it 
		is now synched up.  The encoding of a remote message 
		sometimes added erronous 0xff's because byte copying 
		was done with char instead of unsigned char.  Various 
		aesthetic cleanups
		
2004-04-05  Don Zickus 
OpenDLM Stability cleanups
	* src/kernel/dlmcccp/cccp_init.c:
		swapped a shutdown option to allow a cleaner shutdown
	* src/kernel/dlmdk/clm_clmlock.c:
		fixed groupid assignment on conversion locks
	* src/kernel/dlmdk/clm_purge.c:
		fixed a kernel oops by syncing printk parameters with inputs

2004-04-01   Ben Cahill 
	* docs/WHATIS-opendlm:
	Add references at end.

2004-04-01   Ben Cahill 
	* Throughout tree:
	Check in changes from Computer Associates, shown below with
	dates of 2004-03-10, from Chris Fanning and Don Zickus.
	Add paths and colons to their ChangeLog listings.

2004-03-30  Don Zickus 
OpenDLM handles duplicate packets incorrectly
	* src/kernel/dlmcccp/cccp_proto.c:
		add a tmp_incolor field to temporarily track a packet 
		(or block a port, if one prefers) until the packet is 
		appropriately dealt with on the bottom layers.  Once 
		dealt with the code then syncs the incolor flag with 
		tmp_incolor or un-sets the tmp_incolor flag to mark a 
		rejected packet

2004-03-30  Don Zickus 
Client application causes OpenDLM to crash, disable features for now
	* src/kernel/dlmdk/clm_client.c:
		disable proc fs for each new resource under addclient
	* src/kernel/dlmdk/clm_migtrate.c:
		disable migration code

2004-03-30  Don Zickus 
OpenDLM shutdown can cause crashes if done to quickly and various cleanups

		screen
	* src/kernel/dlmdk/dlm_recover.c:
		timer code cleanup to properly modify and shutdown the timer
	
2004-03-30  Don Zickus 
OpenDLM deadlock detection does not work correctly
	* src/kernel/dlmdk/dlm_deadlock.c:
		the function clmdd_check does not know which lock is 
		being purged as a result of a deadlock.  The code 
		assumed a certain lock when in fact other locks 
		could be purged also.  Expand the fetching of the 
		next node to include these scenarios.  Also adjust 
		the deadlock timeout variable to something smaller 
		like 1 second.
	* src/kernel/dlmdk/clm_main.c:
		adjust the speed of the deadlock detection loop to 
		check every second as opposed to every 6 seconds

2004-03-10  Chris Fanning 
	* src/kernel/dlmdk/clm_clmlock.c:
		fixed dereference of incomp in convert_lock_clm()
		introduced with orphan support changes
	* src/kernel/dlmdk/dlm_kerndd.c:
		fixed incorrect invalid handle check (0 vs -1) in
		haDLM_set_poll() introduced with SAF AIS API support

2004-03-10  Don Zickus 
CCCP dropping packets and broken hops fix, RLDB cleanup and heartbeat fix
	* src/kernel/dlmcccp/cccp_msg.c:
		fixed the way cccp tracks the number of hops a message has 
		been through
	* src/kernel/dlmcccp/cccp_queue.c:
		fixed the way cccp packets are freed of the node queue; 
		this solves the problem of dropped packets
	* src/kernel/dlmdk/clm_direct.c:
		released a semaphore on a failure path
	* src/kernel/dlmdk/clm_locallock.c:
		released a semaphore on a failure path

		cleanup the RLDB entry function header
	* src/user/common/dlm_heartbeat.c:
		fixed the way heartbeat retires on signon failures; this 
		allows a user to cleanup the /var/lib/heartbeat/casual 
		directory without restarting dlmdu

2004-03-10  Don Zickus 
dlmlock error path fixes and heartbeat fixes
	* src/api/api_vms.c:
		removed coded that changed the dlm error codes to return 
		normal.  This caused the failure path to never reports 
		failures under certain conditions
	* src/kernel/dlmdk/clm_alloc.c:
		modified the lock id generation code to be SMP safe and 
		added code to verify a new lock id is not currently in use
	* src/kernel/dlmdk/dlm_proc.c:
		added temporary code to prevent call to specific resource 
		grant queue from crashing the system.  This is temporary 
		because the real fix is involves making sure that a NULL 
		resource is _never_ on the grant queue.  Later this code 
		should be converted into an CLM_ASSERT statement.
	* src/kernel/dlmdk/clm_cti.c:
		fixes the failure path code for when the LKM_SYNCSTS and 
		LKM_BLOCK flag is used.
	* src/user/dlmdu/dlm_heartbeat.c:
		added heartbeat signoff code to clean-up heartbeat 
		resources before exiting.  This is needed to prevent 
		heartbeat signon failures.  Currently the design 
		implementation does not allow for the opendlm to handle a 
		dlmdu restart, therefore signing off from heartbeat is safe 
		for now.  

2004-03-10  Don Zickus 
Cleanup fixes for multi-node Opendlm
	* src/kernel/dlmcccp/cccp_proto.c:
		Instead of dying when an unrequested ACK comes in, just 
		ignore it.  This is safer because the code can not control 
		what type of data may flow in to the ports especially after 
		a failover condition.
	* src/kernel/dlmdk/clm_clmlock.c:
		remove LOCK_WAITING flag.  This sync flag I added in 
		response to the comments in the code, actually broke an 
		optimized hack later on.  So I shall remove it now, in 
		hopes of reimplementing it later on when I can clean things 
		up.
	* src/kernel/dlmdk/clm_cti.c:
		Adds a 'return' command to fix the LCK_SYNCSTS path and 
		changed which _pid_ variables were used to make the code 
		more robust and follow its original intention.  
	* src/kernel/dlmdk/dlm_recover.c:
		Changed the recovery timer code to fix the SMP problem of 
		allocating memory and transitioning states inside the 
		interrupt routine.  In addition the code is now generic 
		enough to handle the RC_MSG_PURGE_WAIT problem.  This 
		problem is solved by checking every second to see the state 
		should continue or not.  The timer fix now delivers a 
		pre-allocated local message to be queued for delivery 
		inside the interrupt handler.  This is a lot safer and 
		cleaner than the previous implementation.  It may not be 
		much faster as it has to travel a little out of its way, 
		but these 'states' are not time critical.  

2004-03-10  Don Zickus 
Allow client to spawn threads with each thread registering with Opendlm
	* src/kernel/dlmdk/dlm_kerndd.c:
		changed getpid() to return tgid instead of pid to 
		correspond with the sys call of get_pid() used in the 
		library

2004-03-10  Chris Fanning 
Opendlm community merges of LKM_SYNCSTS changes
Change provided by Jeffrey Orlin 
	Lock module changes:
	* src/kernel/dlmdk/clm_clmlock.c:
		* clm_lock*() and clm_convert():
		if the LKM_SYNCSTS flag is set and grant_lock() or 
		grant_convert() is called, set clm_status to DLM_SYNC, not 
		DLM_NORMAL
		* cont_lock_clm():
		DLM_SYNC has to be added to the list of states which cannot 
		skip directly to the end.
	* src/api/api_vms.c:
		* clm_lock_reqresp():
		copy the lksb out of the response when the status is DLM_SYNC
	 
	Messaging changes:
	* src/kernel/dlmdk/clm_cti.c:
		* sendudp():
		if LKM_SYNCSTS is set and the status is DLM_NORMAL, call 
		push_seq and return like the code for LKM_BLOCK.
		* sendast():
		if the status is DLM_WAITING and the LKM_SYNCSTS flag is 
		set, call pop_seq and send a DLM_NORMAL message. Clear the 
		LKM_SYNCSTS flag.
	If the LKM_SYNCSTS flag is set:
		clear it
		call pop_seq
		if the status is DLM_SYNC, use sendudp() to send the answer
[May be missing code to clear LKM_SYNCSTS in other cases]

2004-03-10  Chris Fanning 
Opendlm community merges of various cleanups
	* src/kernel/dlmdk/ast_kern.c:
		moved status copy to be more like current OpenDLM code

2004-03-10  Don Zickus 
Fixes for allowing Opendlm to restart without rebooting the machine
	* src/kernel/dlmcccp/cccp_deliver.c:
		modified the shutdown routine of the 
		cccp_msg_delivery_loop.  Basically I wanted all the 
		messages to be handled through their callback so all 
		embedded data structures had released their memory.  
		Because the shutdown procedure closes all the ports, the 
		handling of all messages should be rather quick (if there 
		are any at all).  
	* src/kernel/dlmcccp/cccp_init.c:
		added printk statements to the kmem_cache_destroy functions 
		for debugging purposes if they every fail (so we know which 
		one to chase).  Also uncommented out a chunk of shutdown 
		code that was initially blocked for kernel space.  After 
		some research, I saw no reason to have it commented out and 
		in fact was causing shutdown problems but not having it.  
		The main problem was not shuttting down the send socket, 
		which upon restart would fail to bind because the port was 
		still in use. 
	* src/kernel/dlmcccp/cccp_ports.c:
		added a destroyPorts function which cleans up any 
		straggling messges and deallocates their memory.  The 
		importance here is to help improve the chances of 
		kmem_cache_destroy succeeding.  
	* src/kernel/dlmcccp/cccp_private.h:
		added the prototype for destroyPorts(). 
	* src/kernel/dlmdk/ast_kern.c:
		added printk statements to the kmem_cache_destroy functions 
		for debugging purposes if they every fail (so we know which 
		one to chase).  
	* src/kernel/dlmdk/clm_rldb.c:
		added printk statements to the kmem_cache_destroy functions 
		for debugging purposes if they every fail (so we know which 
		one to chase).  Also added the function destroyRLDBs which 
		performs the same cleanup as destroyPorts().  
	* src/kernel/dlmdk/clm_batch.c:
		added printk statements to the kmem_cache_destroy functions 
		for debugging purposes if they every fail (so we know which 
		one to chase).  
	* src/kernel/dlmdk/dlm_recover.c:
		added printk statements to the kmem_cache_destroy functions 
		for debugging purposes if they every fail (so we know which 
		one to chase).  

2004-03-10  Don Zickus 
Fix kernel oops on error conditions
	* src/kernel/dlmdk/clm_deadlock.c:
		In function clmdd_check, a node is analyzed to determine if 
		it will cause a deadlock scenario.  If the node does cause 
		such a scenario, then it is deleted.  However the pointer 
		to the next node to check is derived from the now defunct 
		node causing the system to crash.  The change corrects the 
		scenario by first determing if the node is defunct, in 
		which case the next node is the head of the list, else 
		continue as normal.  
	* src/kernel/dlmdk/clm_batch.c:
		Check for error by comparing the pointer to NULL instead of 
		a struct field inside the pointer for NULL 

2004-03-10  Don Zickus 
Support for the _THREAD_SAFE flag and fixes for multi-thread issues
	* /src/make/user.mk:
		added -D_THREAD_SAFE flag to invoke the multi-threaded code 
		in the dlm library
	* src/api/api_errno.c:
		swapped the two functions _Dlm_Errno() and 
		init_dlm_errno_hdl and remove an unused variable to prevent 
		a compiler warning for _THREAD_SAFE
	* src/api/api_init.c:
		extern'ed the init_dlm_errno_hdl function to fix a compiler 
		warning for _THREAD_SAFE
	* src/api/api_vms.c:
		added a cast to a function pointer to fix a compiler 
		warning for _THREAD_SAFE
	* src/kernel/dlmdk/clm_cti.c:
		added a spin lock to the per process client stack to 
		prevent the race condition of adding and deleting the head 
		of the queue at the same time 
	* src/kernel/dlmdk/clm_clmlock.c:
		added the flag LOCK_WAITING to the lock state to enforce 
		syncronization between creating the resource and deleting 
		the resource.  The flag already exisited and was used 
		elsewhere in the code.  It seemed someone forgot to set it 
		here

2004-03-10    Don Zickus 
Cleanup the signal handling routines
	* src/include/dlm_kernel.h:
		setup DLM_SIG_LOCK, DLM_SIG_UNLOCK, and DLM_SIG_CHECK 
		macros to mask the differences in the signal handling 
		structs on the various OS versions (linux-2.4, linux-2.4 
		modified, linux-2.6)
	* src/kernel/dlmcccp/cccp_udp.c:
		modified the signal handling routines to incorporate the 
		above macros
	* src/kernel/dlmdk/clm_cti.c:
		added a signal handling trap to k_clm_send() to break-out 
		of an error condition loop in which it was waiting for a 
		valid SiteID number.  This loop would hang any client 
		program until the SiteID was valid.  The problem was that 
		the program assumed the SiteID _would_ become valid.  
	* src/kernel/dlmdk/dlm_workqueue.c:
		modified the signal handling routines to incorporate the 
		above macros

2004-03-10  Don Zickus 
Compilation and configuration clean-ups
	* src/make/kernel.mk:
		removed the CFLAG -DUSE_SIMPLE_LOCKS as this is unsafe to 
		use because it treats all mutexes as spinlocks instead of 
		sleeping locks (ie up/down)
	* src/user/common/dlm_heartbeat.c:
		removed hb_api_core.h because it is not needed any more and 
		fails to compile.
	* configure.ac:
		added a whole bunch of automated checks on kernel 
		configurations.  These checks include:  cpu-type, gcc-type, 
		version info, smp info, signal struct type.  As a result of 
		these new checks, it is easier to build out of the box and 
		for cross-compilation because the dependence is removed 
		from the local system info and put towards the kernel 
		source directory the system is compiling for
