Miller1-16/+0 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.
