Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next
Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following batch contains netfilter updates for your net-next tree: 1) Expose NFT_OSF_MAXGENRELEN maximum OS name length from the new OS passive fingerprint matching extension, from Fernando Fernandez. 2) Add extension to support for fine grain conntrack timeout policies from nf_tables. As preparation works, this patchset moves nf_ct_untimeout() to nf_conntrack_timeout and it also decouples the timeout policy from the ctnl_timeout object, most work done by Harsha Sharma. 3) Enable connection tracking when conntrack helper is in place. 4) Missing enumeration in uapi header when splitting original xt_osf to nfnetlink_osf, also from Fernando. 5) Fix a sparse warning due to incorrect typing in the nf_osf_find(), from Wei Yongjun. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
