Date: Tue, 8 May 2012 09:49:29 +0200 From: pablo@...filter.org To: netfilter-devel@...r.kernel.org Cc: davem@...emloft.net, netdev@...r.kernel.org Subject: [PATCH 00/25] [v2] netfilter updates for net-next (upcoming 3.5) From: Pablo Neira Ayuso <pablo@...filter.org> Hi David, Second version including requested updates. The following patchset contains the Netfilter updates for net-next. Most notably: * The new /proc/sys/net/netfilter/nf_conntrack_helper entry that allows to disable the automatic conntrack helper assignment from Eric Leblond. This patch also spots a warning to inform the user that this behaviour will be removed at some point. The automatic conntrack helper assignment may allows attackers to open hole in the firewall to access the protected network segments (with incorrect configurations). More information on this issue at: https://home.regit.org/netfilter-en/secure-use-of-helpers/ In the near future, all conntrack helpers will be explicitly attached via the CT target, as we longing discussed during the last netfilter workshop. * One new sysctl to translate the input device to vlan device name from Florian Westphal. He required this to get the REDIRECT target working with another sysctl vlan-on-top-of-bridge. * Major improvements in the ip_vs_sync code from Julian Anastasov. They aim to improve scalability and to address possible message loss due to socket overrun under high rate of synchronization messages. * Several minor memory allocation flags fixes from IPVS people contributors. * Eric Leblond's patch spotted one problem that becomes noticeable if a) automatic helper assignment is disabled, and b) if NAT is in use, and c) the CT target is used to attach a non-standard conntrack helper port. This fix comes from myself. * One small update to allow updating the expectation timeout from Kelvie Wong. * Finally, remove ip[6]_queue support since they have been marked as obsolete since long time ago. Now, we have nfnetlink_queue which is way more flexible from myself. You can pull these changes from: git://1984.lsi.us.es/net-next master If time allows, I'd like to send a second batch. There a several patches that are very close to get into shape still on netfilter-devel. Thanks!
