[IMPACT] * ovs-vsswitchd crashes when processing IPv6 neighbor discovery packets with VLAN headers received in a tunnel configured with key=flow or in_key=flow.
* This bug affects us from pushing a change to to the OpenStack Quantum project, which uses OVS on Ubuntu precise quite heavily. [TESTCASE] * Install the current openvswitch package from precise (1.4.0) on two machines. Then, create tunnel ports between the two machines. Next attach a VM to each of the ovs_bridges and add flow table entries which cause traffic entering the bridge to be appended with a VLAN_ID and then output a tunnel port. When IPv6 neighbor discovery packets from the vm enter this port ovs-vswitchd will crash. [Regression Potential] * None [Other Info] * Patch: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff_plain;h=11f84dce005dd14a374ab2ef5f8c25bcf8285a36;hp=776cf91b42f631b4929fffe8ddd2aa06b40ea24c * Mailing list discussion: http://openvswitch.org/pipermail/dev/2012-May/017249.html * Link to patch that exposes this issue in openstack Quantum: https://review.openstack.org/#/c/9416/ -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openvswitch in Ubuntu. https://bugs.launchpad.net/bugs/1021530 Title: [SRU] update to include stable fixes for OVS 1.4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1021530/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
