Notable Fixes

• Reworked c-ares handling (fix for occasional CM crashes)

• Fixed a problem with not including own channel in 802.11k neighbor reports

• Fixed/enhanced logic in CM (improved stability)

• Fixed a corner case that could cause topology changes to fail

• Relaxed default UPnP port forwarding rules to allow ports below 1024

• Fix for not removing an old port forwarding rule when a rule is modified

• Fix for a FSM crash (potential ‘double free’ when misconfigured)

Release 1.4.0.1

Notable Enhancements

• Handling of the Kconfig-driven target_managers_config table was changed so that it can be overridden from the vendor, platform, or 3rdparty layer

Notable Fixes

• Fix for IPv6 address preferred lifetime not set correctly

• Fixed processing of IPv6 RDNSS in case of multiple entries

• Fix for DHCP options not applied immediately after being received

• Fixed code logic for reporting the onboarding status

  • NM2 refactored

• Infrastructure for inspection of data flows (deep packet inspection):

  • added support for flow tags (FSM and plugins)

  • schema updated to add support for IP threat detection

• Infrastructure for collecting and reporting health statistics:

  • IP and DNS monitoring counters: interfaces/ip_dns_telemetry.proto

  • library: src/lib/network_telemetry

• Infrastructure for collecting and reporting data flow statistics:

  • added a new manager (FCM, or Flow Collection Manager)

  • protobuf interface: interfaces/network_metadata.proto

  • library: src/lib/network_metadata

• Sample code for the new features:

• FSM no longer uses pcap as the plugin API

• Additional FSM plugin libraries (for advanced device typing):

  • DHCP (src/lib/dhcp_parse)

  • DNS (src/lib/dns_parse)

  • HTTP (src/lib/http_parse)
