Node A sends master query request to node B which is the master. At this
time lockres happens to be on purgelist. dlm_master_request_handler gets
the dlm spinlock, finds the resource and releases the dlm spin lock.
Right at this dlm_thread on this node could purge the lockres.
dlm_master_request_handler can then acquire lockres spinlock and reply to
Node A that node B is the master even though lockres on node B is purged.
The above scenario will now make node A falsely think node B is the master
which is inconsistent. Further if another node C tries to master the same
resource, every node will respond they are not the master. Node C then
masters the resource and sends assert master to all nodes. This will now
make node A crash with the following message.
dlm_assert_master_handler:1831 ERROR: DIE! Mastery assert from 9, but current

There is a deadlock case which reported by Guozhonghua:
https://oss.oracle.com/pipermail/ocfs2-devel/2014-September/010079.html
This case is caused by &res->spinlock and &dlm->master_lock
misordering in different threads.
It was introduced by commit 8d400b81cc ("ocfs2/dlm: Clean up refmap
helpers"). Since lockres is new, it doesn't not require the
&res->spinlock. So remove it.

Orabug: 19074140
When umount is issued during recovery on the new master that has not
finished remastering locks, it triggers BUG() in
dlm_send_mig_lockres_msg(). Here is the situation:
1) node A has a lock on resource X mastered by node B.
2) node B dies -> node A sets recovering flag for res X
3) Node C becomes the new master for resources owned by the
dead node and is remastering locks of the dead node but
has not finished the remastering process yet.
4) umount is issued on node C.
5) During processing of umount, ignoring unfished recovery,
node C attempts to migrate resource X to node A.
6) node A finds res X in DLM_LOCK_RES_RECOVERING state, considers
it a logic error and sends back -EFAULT.
7) node C asserts BUG() upon seeing EFAULT resp from node B.
Fix is to delay migrating res X till remastering is finished at which
point recovering flag will be cleared on both A and C.

so queue assert_master work
dlm_thread() start running

dlm_assert_master_worker()
send assert master message

receiving the assert_master

dlmlock_remote() send create_lock message to N2, but receive DLM_IVLOCKID,
if it is RECOVERY lockres, it triggers the BUG().
Another BUG() is triggered when N3 become the new master and send
assert_master to N1, N1 will trigger the BUG() because owner doesn't

The inflight reference count, in the lock resource, is taken to pin the resource
in memory. We take it when a new resource is created and release it after a
lock is attached to it. We do this to prevent the resource from getting purged
prematurely.
Earlier this reference count was being taken for locally mastered resources
only. This patch extends the same functionality for remotely mastered ones.
We are doing this because the same premature purging could occur for remotely
mastered resources if the remote node were to die before completion of the
create lock.

During dlm domain shutdown, o2dlm has to free all the lock resources. Ones that
have no locks and references are freed. Ones that have locks and/or references
are migrated to another node.
The first task in migration is finding a target. Currently we scan the lock
resource and find one node that either has a lock or a reference. This is not
very efficient in a parallel umount case as we might end up migrating the
lock resource to a node which itself may have to migrate it to a third node.
The patch scans the dlm->exit_domain_map to ensure the target node is not
leaving the domain. If no valid target node is found, o2dlm does not migrate
the resource but instead waits for the unlock and deref messages that will
allow it to free the resource.

o2dlm was not migrating resources with zero locks because it assumed that that
resource would get purged by dlm_thread. However, some usage patterns involve
creating and dropping locks at a high rate leading to the migrate thread seeing
zero locks but the purge thread seeing an active reference. When this happens,
the dlm_thread cannot purge the resource and the migrate thread sees no reason
to migrate that resource. The spell is broken when the migrate thread catches
the resource with a lock.
The fix is to make the migrate thread also consider the reference map.
This usage pattern can be triggered by userspace on userdlm locks and flocks.

In o2dlm, the master of a lock resource keeps a map of all interested
nodes. This prevents the master from purging the resource before an
interested node can create a lock.
A race between the mastery thread and the mastery handler allowed an
interested node to discover who the master is without informing the
master directly. This is easily fixed by holding the dlm spinlock a
little longer in the mastery handler.

dlm_get_lock_resource() is supposed to return a lock resource with a proper

This patch makes the threads wait in dlm_get_lock_resource() while the mastery

This issue is known to be limited to users using the flock() syscall. For all
