Hi, Eli and Roi. Groups are actually never modified, they are re-created. AFAIR, the group_modify() callback is only used from the ofproto_group_mod_finish() for the newly created group that cannot be accessed by any other threads as it's not published yet. Could you explain in more detail the code path that leads to invalid memory access in you case? Best regards, Ilya Maximets. _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
