From 4820216aa4bcadec2b77340ca7016a9d96a44b9a Mon Sep 17 00:00:00 2001 From: Han Zhou Date: Mon, 21 Oct 2019 18:10:13 -0700 Subject: [PATCH ovn] lflow.c: Fix memory leak of lflow_ref_list_node->ref_name. The ref_name is copied in lflow_resource_add(), but forgot to free in lflow_resource_destroy_lflow(). It can be fixed by freeing it in lflow_resource_destroy_lflow(). However, this field is never really used, so just delete it from lflow_ref_list_node, together with the "type" field. Fixes: d2aa2c7cafead ("ovn-controller: Maintain resource references for logical flows.")
