Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset container Netfilter/IPVS update for net-next: 1) Add UDP tunnel support for ICMP errors in IPVS. Julian Anastasov says: This patchset is a followup to the commit that adds UDP/GUE tunnel: "ipvs: allow tunneling with gue encapsulation". What we do is to put tunnel real servers in hash table (patch 1), add function to lookup tunnels (patch 2) and use it to strip the embedded tunnel headers from ICMP errors (patch 3). 2) Extend xt_owner to match for supplementary groups, from Lukasz Pawelczyk. 3) Remove unused oif field in flow_offload_tuple object, from Taehee Yoo. 4) Release basechain counters from workqueue to skip synchronize_rcu() call. From Florian Westphal. 5) Replace skb_make_writable() by skb_ensure_writable(). Patchset from Florian Westphal. 6) Checksum support for gue encapsulation in IPVS, from Jacky Hu. ====================
