Subject: [PATCH] Fix: libcrmcommon: wait for reply from appropriate controller
commands
ipc_controld.c:reply_expected() wrongly omitted PCMK__CONTROLD_CMD_NODES (which
hasn't been a problem because crm_node uses a mainloop instead of sync dispatch
for that) and CRM_OP_RM_NODE_CACHE (which can be sent via
ipc_client.c:pcmk_ipc_purge_node()).
Because CRM_OP_RM_NODE_CACHE gets only an ack and no further replies, we now
have to be careful not to return true from the controller's dispatch()
function, otherwise crm_node -R would wait forever for more data. That means
we have to check for whether any replies are expected, which means we have to
increment expected replies *before* sending a request (in case it's sync).
Regression introduced in 2.0.5 by ae14fa4a
Fixes T681

Subject: [PATCH] - Fix: controller: don't try to execute agent action at
shutdown Normally, agent execution is not possible at shutdown. However, when
metadata is needed for some action, the agent can be called asynchronously,
and when the metadata action returns, the original action is performed. If
the metadata is initiated before shutdown, but completes after shutdown has
begun, do not try to attempt the original action, so we avoid unnecessary
error logs. - Refactor: controller: de-functionize lrm_state_destroy() It was
a one-liner called once - Log: controller: improve messages for resource
history updates - Low: controller: guard lrm_state_table usage with NULLcheck
It is NULL while draining the mainloop during the shutdown sequence.

Subject: [PATCH] Fix: attrd: avoid race condition when shutting down
This addresses a race condition that can occur when the DC and the attribute
writer are different nodes, and shutting down at the same time. When the DC
controller leaves its Corosync process group, the remaining nodes erase its
transient node attributes (including "shutdown") from the CIB. However if the
(former) DC's attrd is still up, it can win the attribute writer election
called after the original writer leaves. As the election winner, it writes out
all its attributes to the CIB, including "shutdown". The next time it rejoins
the cluster, it will be immediately shut down.
Fixes T138

Subject: [PATCH] Fix: attrd: avoid race condition at writer election
f5263c94 was not a complete fix. The issue may also occur if a remaining node
(not the original DC or writer) wins the attribute writer election after the
original DC's controller has exited but before its attribute manger has exited.
The long-term solution will be to have the attribute manager (instead of the
controller) be in control of erasing transient attributes from the CIB when a
node leaves. This short-term workaround simply has new attribute writers skip
shutdown attributes when writing out all attributes.
Fixes T138
