This series contains the hook mechanism implementation that will be used for
discovery tests.
The hook mechanism is a way to run custom code from tests before/after
processing HCI commands and building events. It is also possible to "cancel"
events if the post event hook returns false. This is necessary because the
current emulator implementation is sequential and does not let having control
about emulator behaviour.
The hooks will only intercept the events which were registered previously using
the hooks API exported by hciemu. If no hooks are added, the emulator will work
as before.
To simplify implementation, default_cmd() was split in two parts: the command
response (command status/complete events) was kept in default_cmd() and "extra"
events were moved to default_cmd completion().
There are four hooks types:
- pre command: before default_cmd() function.
- post command: before sending packet in command status and command complete.
- pre event: before default_cmd_completion() function.
- post event: in send_event() function, before sending the packet.
They can used in external applications like tools/mgmt-tester.
To illustrate this purpose, the following discovery test was implemented using
this new infrastructure:
- Stop discovery for BR/EDR only: this test sends stop command during inquiry,
checks if inquiry cancel is sent and discovering event is disabled.
Note that in current implementation it is not possible to send a stop discovery
before the discovery is finished due to emulator running sequentially during
same mainloop iteration, i.e., the inquiry complete HCI command is sent
immediately after inquiry command.
Comments and suggestions are welcome.
BR,
Bruna Moreira.
Bruna Moreira (2):
emulator: Add new function for running all hooks
tools/mgmt-tester: Add stop discovery for BR/EDR only
Eder Ruiz Maria (6):
emulator: Add support for pre/post command/event hooks
emulator: Add hook only if there aren't other with same type and
opcode
emulator: Export command and event hooks for hciemu user
emulator: Add support for delete a hook
emulator: Split default_cmd() for better command and event handler
emulator: cmd_status() using send_packet() for run hooks easily
