+- Update to new upstream release 1.1.2
+  * This release adds supports for new kernel extensions: tproxy,
+    tunneling, xfrm, osf, conntrack timeouts and helpers. This
+    release deprecates the nftnl_rule_cmp() interface and the low
+    level JSON infrastructure.
+- Remove bufferov.diff (obsolete)
