* origin/topic/jsiwek/ticket946:
Fix memory leaks resulting from 'when' and 'return when' statements.
Fix three bugs with 'when' and 'return when' statements. Addresses #946
- 'when' statements were problematic when used in a function/event/hook
that had local variables with an assigned function value. This was
because 'when' blocks operate on a clone of the frame and the cloning
process serializes locals and the serialization of functions had an
infinite cycle in it (ID -> BroFunc -> ID -> BroFunc ...). The ID
was only used for the function name and type information, so
refactoring Func and subclasses to depend on those two things instead
fixes the issue.
- 'return when' blocks, specifically, didn't work whenever execution
of the containing function's body does another function call before
reaching the 'return when' block, because of an assertion. This was
was due to logic in CallExpr::Eval always clearing the CallExpr
associated with the Frame after doing the call, instead of restoring
any previous CallExpr, which the code in Trigger::Eval expected to
have available.
- An assert could be reached when the condition of a 'when' statement
depended on checking the value of global state variables. The assert
in Trigger::QueueTrigger that checks that the Trigger isn't disabled
would get hit because Trigger::Eval/Timeout disable themselves after
running, but don't unregister themselves from the NotifierRegistry,
which keeps calling QueueTrigger for every state access of the global.
- Moved the Notice::notice event and Notice::policy table to both be hooks.
- Renamed the old Notice::policy to Notice::policy_table and documented it as deprecated.
Added a generic gtpv1_message event generated for any GTP message type.
Added specific events for the create/update/delete PDP context
request/response messages.
Addresses #934.
These cases should be avoidable by fixing scripts where they occur and
they can also help catch typos that would lead to unintentional runtime
behavior.
Adding this already revealed several scripts where a field in an inlined
record was never removed after a code refactor.
