libiptc memory leak - PATCH

["Tomáš Lejdar" <tomas.lejdar@i.cz>]

Hi,
I've used libiptc for some utils and found a little
problem with memory allocation, discused in January and
may be earlier. Here is a small patch (r.1.2.8):

         (*handle)->cache_chain_iteration++;

         if ((*handle)->cache_chain_iteration - (*handle)->cache_chain_heads
!           == (*handle)->cache_num_chains)
                 return NULL;

         return (*handle)->cache_chain_iteration->name;
   }
--- 504,513 ----
         (*handle)->cache_chain_iteration++;

         if ((*handle)->cache_chain_iteration - (*handle)->cache_chain_heads
!           == (*handle)->cache_num_chains){
!                 free((*handle)->cache_chain_heads);
                 return NULL;
+       }

         return (*handle)->cache_chain_iteration->name;
   }
