EMANE

• Added EMANE prefix configuration when looking for emane model manifest files
  • requires configuring emane_prefix in /etc/core/core.conf

Cleanup

Issues

• #246 - Fixed network to network link handling when reading xml files
• #236 - Fixed storing/reading of link configuration values within xml files
• #170 - FRR Service
• #155 - EMANE path configuration

CORE 5.2.2

Enhancements:

• adds back in core-daemon udp support for coresendmsg, people may have depended on previously for certain scenarios

Bug Fixes:

• fixes issue in GUI that would prevent moving nodes during mobility scenarios

CORE 5.2.1

Build:

• documentation no longer builds by default, must use configure flag
• added configure flag to allow only building vcmd
• sphinx will no long be required when not building documentation

Services:

• Added source NAT service
• Fixed DHCP service for Ubuntu 18.04

ISSUES:
#188 - properly remove session on delete TLV API call
#192 - updated default gnome terminal command for nodes to be Ubuntu 18.04 compatible
#193 - updates to service validation, will retry on failure and better exception logging
#195 - TLV link message data fix
#196 - fix to avoid clearing out default services
#197 - removed wireless_link_all API from EmuSession
#216 - updated default WLAN bandwidth to 54Mbps
#223 - fix to saving RJ45 to session XML files

CORE 5.2

• EMANE
  • support for external transports, a new tab in the GUI will provide a checkbox for enabling external transports and the following options
    • platformendpoint - 127.0.0.1:40001
    • transportendpoint - 127.0.0.1:50002
• GUI
  • updated help menu links to point at GitHub
• Configuration
  • refactored configuration storage within the code base to use key/value dictionaries instead of pairs of tuples representing keys/values
  • new methods for storing and accessing these configurations, impacts session.options, session.metadata, session.services, and session.emane
• Services
  • updates services to have class variables without the "_" prefix, "_name" is now "name"
  • changes services to validate immediately after running startup commands
  • added different validation modes for services using the "validation_mode" parameter
    • BLOCKING - the startup commands alone are considered validation and their exit codes will be used as validation
    • NON-BLOCKING - the startup commands are not enough and separate validation commands are ran to determine validation
    • TIMER - you are not sure how to validate, but would consider waiting around for a period of time, good enough
  • "validation_timer" an integer can be set to provide time for validation commands or used as a timer alone in TIMER mode, time to wait in seconds
  • "executables" can be set to provide a tuple of commands you expect to exist within CORE's path for operation, if any executable is not found the service will not load
  • "dependencies" can be set to provide a tuple of other service names, which will cause these services to be started in dependent order, assuming the node has all required services set
• XML
  • the lxml library is now being used for emane and core xml file generation
  • there is a new simpler structure for core xml files
  • section kept same as before for now, for those that depend on it

ISSUES:
#167 - configuration cleanup
#168 - services cleanup
#171 - ovs linkconfig parameter name issue
#172 - OVS mode and control network
#173 - xml cleanup
#177 - All nodes get the same service config - OvsService
#181 - Core Python package changes to be implemented in sample custom service example
#184 - allow passing in a Session class to CoreEmu.create_session() helper
