This affects the 0.98 release of NetworkManager and has already been fixed in newer releases. * Backporting fixes from upstream release is required to prevent NetworkManager from faulting which breaks networking on most Desktop releases. * All patches applied are already accepted upstream and newer Ubuntu releases are not affected. * Upgrading NetworkManager to 0.9.8.8-0ubuntu7.3 prior to updating libnl-3.2.21-1ubuntu1 is required to prevent NetworkManager crashing. [Test Case] * Reproduce crash test: 1. Download 14.04.03 Desktop iso, amd64 2. Launched in a VM, run from iso 3. In terminal, enable proposed 4. sudo apt-get install libnl-3-200 libnl-genl-3-200 libnl-route-3-200 5. sudo restart network-manager # note the nm-applet disappears as NM has now crashed, no network conn. 6. dmesg to confirm network-manager crash 7. sudo dpkg --install gir1.2-networkmanager-1.0_0.9.8.8-0ubuntu7.3_amd64.deb libnm-glib4_0.9.8.8-0ubuntu7.3_amd64.deb libnm-glib-vpn1_0.9.8.8-0ubuntu7.3_amd64.deb libnm-util2_0.9.8.8-0ubuntu7.3_amd64.deb network-manager_0.9.8.8-0ubuntu7.3_amd64.deb 8. sudo start network-manager # nm-applet reappears, network connectivity restored * Successful upgrade test: 1. Download 14.04.03 Desktop iso, amd64 2. Launched in a VM, run from iso 3. In a terminal, sudo dpkg --install gir1.2-networkmanager-1.0_0.9.8.8-0ubuntu7.3_amd64.deb libnm-glib4_0.9.8.8-0ubuntu7.3_amd64.deb libnm-glib-vpn1_0.9.8.8-0ubuntu7.3_amd64.deb libnm-util2_0.9.8.8-0ubuntu7.3_amd64.deb network-manager_0.9.8.8-0ubuntu7.3_amd64.deb 4. sudo restart network-manager # NM still runs, no crash, net up 5. enable trusty-proposed in /etc/apt/sources.list 6. sudo apt-get update 7. sudo apt-get install libnl-3-200 libnl-genl-3-200 libnl-route-3-200 8. sudo restart network-manager # NM still runs, no crash, net up. [Regression Potential] * NetworkManager is a highly visible package, so testing NetworkManager functionality is critical. The patch does address the crash specificly introduced by the updated libnl SRU. * We need to ensure that users have installed this NetworkManager update before installing libnl3 update (special phasing needed). [Original Description] Testing out proposed libnl-3 package[1] exposed a bug in NM 0.98. After installing updated libnl3 and restarting networkmanager, NM crashes with: /var/log/syslog shows: init: network-manager main process (1057) killed by SEGV signal init: network-manager main process ended, respawning init: network-manager main process (1065) killed by SEGV signal init: network-manager respawning too fast, stopped The bug has been fixed in upstream 0.98 with these patches: http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=8e4576b9fdb5c888d20a13aa2cc198df790dba54 http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=65981edb9f562c07e78815c98093da67c50bfdcf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1539634/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
