2024-03-06ctdb-server: Implement CTDB_CONTROL_START_IPREALLOCATEVinit Agnihotri1-0/+3
Trigger a "startipreallocate" event, but only if in RUNNING runstate. "startipreallocate" is intended to allow an NFS server to be put into grace on all nodes before any locks are released as part of releaseip during failover. If node A is leader and initiates a takeover run then node B may be connected/active but may not have completed startup. In this case, the attempt to put NFS-Ganesha into grace on node B will fail, startipreallocate will fail, and the node will be banned.

2023-12-15ctdb: add/implement CTDB_CONTROL_TCP_CLIENT_PASSEDStefan Metzmacher1-0/+3
With multichannel a tcp connection is registered first with a temporary smbd process, that calls CTDB_CONTROL_TCP_CLIENT first and then passes the tcp connection to the longterm smbd that already handles all connections belonging to the specific client_guid. That smbd process calls CTDB_CONTROL_TCP_CLIENT again, but the 'tickle' information is already there. When the temporary smbd process exists/disconnects from ctdb or calls CTDB_CONTROL_TCP_CLIENT_DISCONNECTED, the 'tickle' information is removed, while the longterm smbd process still serves the tcp connection.

Node ID is a poorly defined concept, indicating the slot in the node map where the IP address was found. This signed value also ends up compared to num_nodes, which is unsigned, producing unwanted warnings. Just return the PNN because this what both callers really want.

The comment immediately above this code says "don't allow local clients to attach" and then looks up the client ID regardless of whether the request is local or remote. This means that an intentional remote attach from a client will not work correctly. No real client should ever do that since clients attach so they an access databases locally.
