2004-04-15 Don Zickus <don.zickus@ca.com>
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 <stanley.wang@linux.intel.com>
* src/user/common/dlm_ccm.c:
Ingnore old membership message and code cleaning.
2004-04-13 Stanley Wang <stanley.wang@linux.intel.com>
* src/kernel/dlmcccp/cccp_ports.c:
Clean all pending message in destroyPorts().
2004-04-13 Stanley Wang <stanley.wang@linux.intel.com>
* src/user/common/dlm_ccm.c:
Use "SA_CLM_NODE_LEFT" macro instead of integer value.
2004-04-09 Stanley Wang <stanley.wang@linux.intel.com>
* 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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <ben.m.cahill@intel.com>
* docs/WHATIS-opendlm:
Add references at end.

2004-03-30 Don Zickus <don.zickus@ca.com>
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 <don.zickus@ca.com>
Client application causes OpenDLM to crash, disable features for now
* src/kernel/dlmdk/clm_client.c:

screen
* src/kernel/dlmdk/dlm_recover.c:
timer code cleanup to properly modify and shutdown the timer
2004-03-30 Don Zickus <don.zickus@ca.com>
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 <chris.fanning@ca.com>
* 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 <don.zickus@ca.com>
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
* src/kernel/dlmdk/clm_resource.c:
cleanup the RLDB entry when refcount is zero
* src/kernel/dlmdk/clm_rldb.c:
cleanup the RLDB entry function
* src/kernel/dlmcccp/cccp_rldb.c(??????):
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <chris.fanning@ca.com>
Opendlm community merges of LKM_SYNCSTS changes
Change provided by Jeffrey Orlin <jeff@intersystems.com>
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 <chris.fanning@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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 <don.zickus@ca.com>
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
2004-03-04 Ben Cahill <ben.m.cahill@intel.com>
