+Subject: bgpd: Remove extra lock on interior table node
+X-Git-Url: http://git.ozo.com/?p=quagga-next.git;a=commitdiff_plain;h=765ec33b44a7d8cf9290acd19dc19953df4ddb0d

+bgpd: Remove extra lock on interior table node
+
+If the radix tree creates an extra interior node in bgp_node_get(),
+it locks the interior node even though this node is not returned to
+the caller, so it may never be unlocked. The lock prevents this node
+from being deleted.
+
+* bgpd/bgp_table.c
+  * bgp_node_get(): Remove lock on interior node which prevents
+    proper node deletion
