v0.26

Fuddly 0.26

This release brings several enhancements and new features as well as fixing bugs and doing some cleanup. Here under what is the most noteworthy:

• Scenario infrastructure enhancements and fuzzing features (refer to the documentation available here):

  • Add scenario fuzzing features to play around the protocol sequence, the timing constraints and the data emitted.
  • Reorganize and add callbacks that triggers before sending data and assign them to a step (do_before_data_processing, do_before_sending).
  • Add the ability for a step to trigger the sending of multiple data.
  • Improve the graphical display (more information, current step identified, ...) and add the ability to open it automatically while fuddly run through a scenario.
  • New FeedbackHandler class to simplify feedback handling, especially with scenario callbacks.
  • Revamp the transition condition checking logic.

• Add an Evolutionary fuzzing infrastructure (refer to the documentation available here).

• New data model helpers/templates:

  • Add helpers for describing XML data.
  • Regroup all the data model helpers in the new framework.dmhelpers package.

• Enhance and add new options to the NetworkTarget:

  • Add new parameters target_address and wait_for_client to enable more behavior options for an interface configured in server mode (refer to the documentation).
  • Remove the artificial correlation between the sending_delay and feedback_timeout attributes.

• Add the ability to change the min/max values of non-terminal node children through the method set_subnode_minmax().

• Add an HTTP data model.

API modification

• The parameters mini and maxi of INT-based classes (e.g., UINT16_be, SINT8, ...) have been respectively renamed min and max.

• Redesign Data() and DataModel() to make them content-agnostic; resulting in changing some usage patterns.
