2014-01-09netfilter: nf_tables: fix chain type module reference handlingPatrick McHardy
The chain type module reference handling makes no sense at all: we take a reference immediately when the module is registered, preventing the module from ever being unloaded. Fix by taking a reference when we're actually creating a chain of the chain type and release the reference when destroying the chain.

2014-01-07IPv6: add the option to use anycast addresses as source addresses in echo replyFX Le Bail
This change allows to follow a recommandation of RFC4942. - Add "anycast_src_echo_reply" sysctl to control the use of anycast addresses as source addresses for ICMPv6 echo reply. This sysctl is false by default to preserve existing behavior. - Add inline check ipv6_anycast_destination(). - Use them in icmpv6_echo_reply(). Reference: RFC4942 - IPv6 Transition/Coexistence Security Considerations (http://tools.ietf.org/html/rfc4942#section-2.1.6) 2.1.6. Anycast Traffic Identification and Security [...] To avoid exposing knowledge about the internal structure of the network, it is recommended that anycast servers now take advantage of the ability to return responses with the anycast address as the source address if possible.

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.

2014-01-03net: net_cls: move cgroupfs classid handling into coreDaniel Borkmann
Zefan Li requested [1] to perform the following cleanup/refactoring: - Split cgroupfs classid handling into net core to better express a possible more generic use. - Disable module support for cgroupfs bits as the majority of other cgroupfs subsystems do not have that, and seems to be not wished from cgroup side. Zefan probably might want to follow-up for netprio later on. - By this, code can be further reduced which previously took care of functionality built when compiled as module. cgroupfs bits are being placed under net/core/netclassid_cgroup.c, so that we are consistent with {netclassid,netprio}_cgroup naming that is under net/core/ as suggested by Zefan. No change in functionality, but only code refactoring that is being done here.

2014-01-02sctp: Remove outqueue empty stateVlad Yasevich
The SCTP outqueue structure maintains a data chunks that are pending transmission, the list of chunks that are pending a retransmission and a length of data in flight. It also tries to keep the emtpy state so that it can performe shutdown sequence or notify user. The problem is that the empy state is inconsistently tracked. It is possible to completely drain the queue without sending anything when using PR-SCTP. In this case, the empty state will not be correctly state as report by Jamal Hadi Salim <jhs@mojatatu.com>. This can cause an association to be perminantly stuck in the SHUTDOWN_PENDING state. Additionally, SCTP is incredibly inefficient when setting the empty state. Even though all the data is availaible in the outqueue structure, we ignore it and walk a list of trasnports. In the end, we can completely remove the extra empty state and figure out if the queue is empty by looking at 3 things: length of pending data, length of in-flight data, and exisiting of retransmit data. All of these are already in the strucutre.

2014-01-01net: llc: fix order of evaluation in llc_conn_ac_inc_vr_by_1Daniel Borkmann
Function llc_conn_ac_inc_vr_by_1() evaluates via macro PDU_GET_NEXT_Vr() into ... llc_sk(sk)->vR = ++llc_sk(sk)->vR & 0xffffffffffffff7f ... but the order in which the side effects take place is undefined because there is no intervening sequence point. As llc_sk(sk)->vR is written in llc_sk(sk)->vR (assignment left-hand side) and written in ++llc_sk(sk)->vR & 0xffffffffffffff7f this might possibly yield undefined behavior. The final value of llc_sk(sk)->vR is ambiguous, because, depending on the order of expression evaluation, the increment may occur before, after, or interleaved with the assignment. In C, evaluating such an expression yields undefined behavior. Since we're doing the increment via PDU_GET_NEXT_Vr() macro and the only place it is being used is from llc_conn_ac_inc_vr_by_1(), in order to increment vR by 1 with a follow-up optimized modulo, rewrite the expression into ((vR + 1) & CONST) in order to fix this.
