Pablo Neira Ayuso says: ==================== netfilter/IPVS updates for net-next The following patchset contains Netfilter updates for your net-next tree, they are: * Add full port randomization support. Some crazy researchers found a way to reconstruct the secure ephemeral ports that are allocated in random mode by sending off-path bursts of UDP packets to overrun the socket buffer of the DNS resolver to trigger retransmissions, then if the timing for the DNS resolution done by a client is larger than usual, then they conclude that the port that received the burst of UDP packets is the one that was opened. It seems a bit aggressive method to me but it seems to work for them. As a result, Daniel Borkmann and Hannes Frederic Sowa came up with a new NAT mode to fully randomize ports using prandom. * Add a new classifier to x_tables based on the socket net_cls set via cgroups. These includes two patches to prepare the field as requested by Zefan Li. Also from Daniel Borkmann. * Use prandom instead of get_random_bytes in several locations of the netfilter code, from Florian Westphal. * Allow to use the CTA_MARK_MASK in ctnetlink when mangling the conntrack mark, also from Florian Westphal. * Fix compilation warning due to unused variable in IPVS, from Geert Uytterhoeven. * Add support for UID/GID via nfnetlink_queue, from Valentina Giusti. * Add IPComp extension to x_tables, from Fan Du. ==================== Signed-off-by: David S.
