Thus the zone has to be set before the packet is picked up by the connection tracker. This is done by means of 'conntrack templates' which are conntrack structures used solely to pass this info from one netfilter hook to the next. The iptables CT target instantiates these connection tracking templates once per rule, i.e. the template is fixed/tied to particular zone, can be read-only and therefore be re-used by as many skbs simultaneously as needed. We can't follow this model because we want to take the zone id from an sreg at rule eval time so we could e.g. fill in the zone id from the packets vlan id or a e.g. nftables key : value maps. To avoid cost of per packet alloc/free of the template, use a percpu template 'scratch' object and use the refcount to detect the (unlikely) case where the template is still attached to another skb (i.e., previous skb was nfqueued ...).

Prepare for this: remove the 'label_got' boolean in favor of a switch statement that can be extended in next patch. As we already have that in the set_destroy function place that in a separate function and call it from the set init function.

This bitmap uses two bits to represent one element. These two bits determine the element state in the current and the future generation that fits into the nf_tables commit protocol. When dumping elements back to userspace, the two bits are expanded into a struct nft_set_ext object. If no NFTA_SET_DESC_SIZE is specified, the existing automatic set backend selection prefers bitmap over hash in case of keys whose size is <= 16 bit. If the set size is know, the bitmap set type is selected if with 16 bit kets and more than 390 elements in the set, otherwise the hash table set implementation is used. For 8 bit keys, the bitmap consumes 66 bytes. For 16 bit keys, the bitmap takes 16388 bytes. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> 2017-02-08netfilter: nf_tables: add space notation to setsPablo Neira Ayuso3-5/+19 The space notation allows us to classify the set backend implementation based on the amount of required memory. This provides an order of the set representation scalability in terms of memory. The size field is still left in place so use this if the userspace provides no explicit number of elements, so we cannot calculate the real memory that this set needs. This also helps us break ties in the set backend selection routine, eg. two backend implementations provide the same performance.

This is required by the new bitmap set type coming in a follow up patch which has no real struct nft_set_ext, so it has to allocate it based on the two bit compact element representation.

Miller53-640/+576 Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree, they are: 1) Stash ctinfo 3-bit field into pointer to nf_conntrack object from sk_buff so we only access one single cacheline in the conntrack hotpath. Patchset from Florian Westphal. 2) Don't leak pointer to internal structures when exporting x_tables ruleset back to userspace, from Willem DeBruijn. This includes new helper functions to copy data to userspace such as xt_data_to_user() as well as conversions of our ip_tables, ip6_tables and arp_tables clients to use it. Not surprinsingly, ebtables requires an ad-hoc update. There is also a new field in x_tables extensions to indicate the amount of bytes that we copy to userspace. 3) Add nf_log_all_netns sysctl: This new knob allows you to enable logging via nf_log infrastructure for all existing netnamespaces. Given the effort to provide pernet syslog has been discontinued, let's provide a way to restore logging using netfilter kernel logging facilities in trusted environments. Patch from Michal Kubecek. 4) Validate SCTP checksum from conntrack helper, from Davide Caratti. 5) Merge UDPlite conntrack and NAT helpers into UDP, this was mostly a copy&paste from the original helper, from Florian Westphal. 6) Reset netfilter state when duplicating packets, also from Florian. 7) Remove unnecessary check for broadcast in IPv6 in pkttype match and nft_meta, from Liping Zhang. 8) Add missing code to deal with loopback packets from nft_meta when used by the netdev family, also from Liping. 9) Several cleanups on nf_tables, one to remove unnecessary check from the netlink control plane path to add table, set and stateful objects and code consolidation when unregister chain hooks, from Gao Feng. 10) Fix harmless reference counter underflow in IPVS that, however, results in problems with the introduction of the new refcount_t type, from David Windsor. 11) Enable LIBCRC32C from nf_ct_sctp instead of nf_nat_sctp, from Davide Caratti. 12) Missing documentation on nf_tables uapi header, from Liping Zhang. 13) Use rb_entry() helper in xt_connlimit, from Geliang Tang. ==================== Signed-off-by: David S.

Miller <davem@davemloft.net> 2017-02-03tcp: clear pfmemalloc on outgoing skbEric Dumazet1-0/+7 Josef Bacik diagnosed following problem : I was seeing random disconnects while testing NBD over loopback. This turned out to be because NBD sets pfmemalloc on it's socket, however the receiving side is a user space application so does not have pfmemalloc set on its socket. This means that sk_filter_trim_cap will simply drop this packet, under the assumption that the other side will simply retransmit. Well we do retransmit, and then the packet is just dropped again for the same reason. It seems the better way to address this problem is to clear pfmemalloc in the TCP transmit path. pfmemalloc strict control really makes sense on the receive path.

This enables bridge driver to map vlan to tunnel_info at ingress and egress. It uses the kernel dst_metadata infrastructure. The initial use case is vlan to vni bridging, but the api is generic to extend to any tunnel_info in the future: - Uapi to configure/unconfigure/dump per vlan tunnel data - netlink functions to configure vlan and tunnel_info mapping - Introduces bridge port flag BR_LWT_VLAN to enable attach/detach dst_metadata to bridged packets on ports. off by default. - changes to existing code is mainly refactor some existing vlan handling netlink code + hooks for new vlan tunnel code - I have kept the vlan tunnel code isolated in separate files. - most of the netlink vlan tunnel code is handling of vlan-tunid ranges (follows the vlan range handling code). To conserve space vlan-tunid by default are always dumped in ranges if applicable. Use case: example use for this is a vxlan bridging gateway or vtep which maps vlans to vn-segments (or vnis). iproute2 example (patched and pruned iproute2 output to just show relevant fdb entries): example shows same host mac learnt on two vni's and vlan 100 maps to vni 1000, vlan 101 maps to vni 1001 before (netdev per vni): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan1001 vlan 101 master bridge 00:02:00:00:00:03 dev vxlan1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan1000 vlan 100 master bridge 00:02:00:00:00:03 dev vxlan1000 dst 12.0.0.8 self after this patch with collect metdata in bridged mode (single netdev): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan0 vlan 101 master bridge 00:02:00:00:00:03 dev vxlan0 src_vni 1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan0 vlan 100 master bridge 00:02:00:00:00:03 dev vxlan0 src_vni 1000 dst 12.0.0.8 self CC: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S.
