Public bug reported: Similar to bug 1570466 but a different root cause. It was identified that memory leaked on continuously adding/removing vhost_user ports in openvswitch-dpdk. See the other bug for reproduction suggestion.
Fortunately for this bug a fix is already upstream in the openvswitch 2.5 branch. In particulr for this bug we need: d9df7b9206831631ddbd90f9cbeef1b4fc5a8e89 netdev-dpdk: Fix memory leak in netdev_dpdk_vhost_destruct(). But there are more critical ones related to openvswitch-dpdk: a39aa7e10d033e3ed15b16bd101f655aa1db8135 dpif-netdev: report numa node number on pmd thread create failure e099c86ca432d1daeaf8edb66225e7edf061c0b0 netdev-dpdk: vhost: Fix txq enabling in the absence of notifications. 3b70d8fcca23d9fed2f2a2c2e9eb428e4a202123 netdev-dpdk: Fix crash when changing the vhost-user port. f61053debcb466d8bfec31070f0826e3c0e3c727 INSTALL.DPDK: remove issue with QEMU v2.4.0 and dpdkvhostuser 05a00f12f2c4e25077f0ca55f7f6734908932abf netdev-dpdk: fix mbuf leaks I understand we generally wait for the 2.5.1 release which will get some extra test and checks, but I hope that shouldn't be too far away. So please merge the 2.5.1 point release of openvswitch as soon as available to fix this issue. ** Affects: dpdk (Ubuntu) Importance: High Status: Triaged ** Affects: openvswitch-dpdk (Ubuntu) Importance: High Assignee: James Page (james-page) Status: Triaged ** Also affects: openvswitch-dpdk (Ubuntu) Importance: Undecided Status: New ** Changed in: dpdk (Ubuntu) Status: New => Triaged ** Changed in: dpdk (Ubuntu) Importance: Undecided => High ** Changed in: openvswitch-dpdk (Ubuntu) Status: New => Triaged ** Changed in: openvswitch-dpdk (Ubuntu) Importance: Undecided => High ** Changed in: openvswitch-dpdk (Ubuntu) Assignee: (unassigned) => James Page (james-page) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573091 Title: Adding/removing dpdk ports leaks memory in openvswitch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpdk/+bug/1573091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
