v0.8.0

Added

• Flows:
  • Add packet injector to generate traffic between two interfaces
  • Support Geneve tunneling
  • Add support for MPLS over both UDP and GRE
  • Add sFlow tunneling support
  • Add 'Application' metadata that contains the last layer type
• Gremlin:
  • New 'Metrics' Gremlin step to get all the metrics associated to a
    set of flows
  • New 'Values' step which returns values of a property:
    ex: G.V().Values('Name')
  • New 'Sum' step that returns aggregation over named node property:
    ex: G.Flows().Sum('Metric.ABBytes')
  • New 'Regex' predicated to use regular expression when querying graph
    and flows
  • New 'At' alias for 'Context' and allow more user friendly time definition
    ex: g.At('-5m').V()
  • New 'Within' filter for flows
  • New 'Since' predicate to select flows
  • New 'CaptureNode' step to get the capture nodes of a set of flows
• OpenStack:
  • Add support for Keystone V3
  • Autodetect Skydive agent running inside a virtual machine
• WebUI:
  • Add packet injector tab
  • Add support for zoom-in zoom-out and reset
  • Add the "famous" "mmmgnmm bob effect"
• Misc:
  • Experimental support for TLS communication between agents and analyzer
  • Vagrantfile to bootstrap a 3 nodes setup

Changed

• Flows:
  • Manage captures from the analyzer to handle use case like setting capture
    point on all the interfaces between two nodes
  • Simplify packet processing and remove timeout mechanisms at the probe level
  • Correct packet length for outer/inner packets in tunnels
• Topology:
  • Move 'fabric' probe onto the analyzer and add a WebSocket API
• WebUI:
  • Update timeslider to use delta instead of date
  • Restore discovery and conversation views
  • Fix node selection issue after agent Resync
• Bugs fixes:
  • Many bugfixes around network namespaces that caused Goroutines to run
    in the wrong namespace that resulted in flow captures and packet injection
    errors
  • Fix leak of namespace fd in docker probe
• Build:
  • Do not integrate generated file anymore
