From 3594990b070f8cd6df9d7693cacb8ff4d91429fe Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Thu, 28 Apr 2011 16:34:56 -0700 Subject: [PATCH] datapath: Avoid freeing wild pointer in corner case. In odp_flow_cmd_new_or_set(), if flow_actions_alloc() fails in the "new flow" case, then flow_put() will kfree() the new flow's 'sf_acts' pointer, but nothing has initialized that pointer. Initialize the pointer to NULL to avoid the problem. Found by inspection.
