The ConnMan project provides a daemon for managing internet connections within embedded devices running the Linux operating system. The Connection Manager is designed to be slim and to use as few resources as possible, so it can be easily integrated. It is a fully modular system that can be extended, through plug-ins, to support all kinds of wired or wireless technologies.

ConnMan 1.32

BY Patrik Flykt ON Apr 21, 2016

Connman 1.32 was released Monday, April 18th, 2016.

This release of ConnMan removes support for Bluez 4.x, which saw its last upstream release 3½ years ago. Bluez 5 has been supported since with ConnMan version 1.11 for a bit over three years now with all distributions providing Bluez 5 for a long time already.

With version 1.32 being mostly a bug fix release, issues fixed include:

  • Support tun and tap devices for VPNs (Hendrik Donner)
  • Support for iptables 1.6 (Wu Zheng)
  • Support for displaying Clock API settings in connmanctl (Saurav Babu)
  • Interfaces starting with ve- and vb- created by systemd have been added to the default interface blacklist (Krisztian Litkey)
  • Fix DHCP issues with renewal of nameservers  (Naveen Singh), timeservers, MTU (Patrik Flykt), timer removal and sending Discover after obtaining link-local address (Saurav Babu)
  • Re-enable fallback nameservers when the service changes to one with no nameservers specified (Patrik Flykt)
  • Properly remove P2P peers when disabling P2P technology (John Ernberg)
  • Prevent wpa_supplicant memory leak by calling RemoveNetwork when the WiFi network deauthenticates ConnMan (Naveen Singh)
  • Restore previous ip_forward value in /proc when tethering is disabled (Patrik Flykt) and allow raw PSK key when tethering via WiFi (Jose Blanquicet)
  • Build-time detection of execinfo.h needed for optional or no backtrace implementation in uClibc and musl (Yann Morin)
  • Simplification of gateway selection (Patrik Flykt)

Thanks for all the hard work and bugfixes go to Hendrik Donner, John Ernberg, Jose Blanquicet, Krisztian Litkey, Marcel Holtmann, Milind Ramesh Murhekar, Naveen Singh, Niraj Kumar Goit, Nishant Chaprana, Patrik Flykt, Ravi Prasad RK, Saurav Babu, Slava Monich, Wu Zheng, Yann Morin, Intel, Jolla, Magneti Marelli, Nest and Samsung.
