+This is a summary of the main changes in the kernel that diverge from mainline.
+
+* added net/netfilter/xt_qtaguid*
+* imported then modified net/netfilter/xt_quota2.c from xtables-addons project
+* fixes in net/netfilter/ip6_tables.c
+* modified ip*t_REJECT.c
+* modified net/netfilter/xt_socket.c
+
+A few comments on the kernel configuration:
+
+* xt_qtaguid masquerades as xt_owner and relies on xt_socket and itself relies on the connection tracker.
+* The connection tracker can't handle large SIP packets, it must be disabled.
+* The modified xt_quota2 uses the NFLOG support to notify userspace.
