Title:
Some protobuf Closure objects can access dead objects
Status in Mir:
Fix Committed
Status in Mir 0.12 series:
Fix Released
Status in mir package in Ubuntu:
Fix Released
Bug description:
ProtobufMessageProcessor::dispatch will create a protobuf closure
object that references the ProtobufMessageProcessor "this" pointer.
The closure/callback object may be invoked by a different thread (e.g.
SessionMediator::exchange_buffer). Since there's no protection there
can be a race between dropping a connection (which destroys the
ProtoBufMessageProcessor) and the callback being invoked by a
compositor thread.
