+Subject: [PATCH 1/3] ospfclient: Ensure ospf_apiclient_lsa_originate cannot
+ accidently write into stack
+
+Even though OSPF_MAX_LSA_SIZE is quite large and holds the upper bound
+on what can be written into a lsa, let's add a small check to ensure
+it is not possible to do a bad thing.
+
+This wins one of the long standing bug awards.  2003!
+
+Fixes: #11602
