2012-05-17netfilter: xt_hashlimit: use _ALL macro to reject unknown flag bitsFlorian Westphal
David Miller says: The canonical way to validate if the set bits are in a valid range is to have a "_ALL" macro, and test: if (val & ~XT_HASHLIMIT_ALL) goto err;" make it so. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2012-05-16fq_codel: should use qdisc backlog as thresholdEric Dumazet
codel_should_drop() logic allows a packet being not dropped if queue size is under max packet size. In fq_codel, we have two possible backlogs : The qdisc global one, and the flow local one. The meaningful one for codel_should_drop() should be the global backlog, not the per flow one, so that thin flows can have a non zero drop/mark probability.

Otherwise e.g. device authorization for the sockets will fail with ENOTCONN as user space things that there is no baseband link.

2012-05-14Bluetooth: notify userspace of security level changeGustavo Padovan
It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.

2012-05-13batman-adv: improve unicast packet (re)routingAntonio Quartulli
In case of a client X roaming from a generic node A to another node B, it is possible that a third node C gets A's OGM but not B's. At this point in time, if C wants to send data to X it will send a unicast packet destined to A. The packet header will contain A's last ttvn (C got A's OGM and so it knows it). The packet will travel towards A without being intercepted because the ttvn contained in its header is the newest for A. Once A will receive the packet, A's state will not report to be in a "roaming phase" (because, after a roaming, once A sends out its OGM, all the changes are committed and the node is considered not to be in the roaming state anymore) and it will match the ttvn carried by the packet. Therefore there is no reason for A to try to alter the packet's route, thus dropping the packet because the destination client is not there anymore. However, C is well aware that it's routing information towards the client X is outdated as it received an OGM from A saying that the client roamed away. Thanks to this detail, this patch introduces a small change in behaviour: as long as C is in the state of not knowing the new location of client X it will forward the traffic to its last known location using ttvn-1 of the destination. By using an older ttvn node A will be forced to re-route the packet. Intermediate nodes are also allowed to update the packet's destination as long as they have the information about the client's new location. Signed-off-by: Antonio Quartulli <ordex@autistici.org>

Fair Queue Codel packet scheduler Principles : - Packets are classified (internal classifier or external) on flows. - This is a Stochastic model (as we use a hash, several flows might be hashed on same slot) - Each flow has a CoDel managed queue. - Flows are linked onto two (Round Robin) lists, so that new flows have priority on old ones. - For a given flow, packets are not reordered (CoDel uses a FIFO) - head drops only. - ECN capability is on by default. - Very low memory footprint (64 bytes per flow) tc qdisc ... fq_codel [ limit PACKETS ] [ flows number ] [ target TIME ] [ interval TIME ] [ noecn ] [ quantum BYTES ] defaults : 1024 flows, 10240 packets limit, quantum : device MTU target : 5ms (CoDel default) interval : 100ms (CoDel default) Impressive results on load : class htb 1:1 root leaf 10: prio 0 quantum 1514 rate 200000Kbit ceil 200000Kbit burst 1475b/8 mpu 0b overhead 0b cburst 1475b/8 mpu 0b overhead 0b level 0 Sent 43304920109 bytes 33063109 pkt (dropped 0, overlimits 0 requeues 0) rate 201691Kbit 28595pps backlog 0b 312p requeues 0 lended: 33063109 borrowed: 0 giants: 0 tokens: -912 ctokens: -912 class fq_codel 10:1735 parent 10: (dropped 1292, overlimits 0 requeues 0) backlog 15140b 10p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 7.1ms class fq_codel 10:4524 parent 10: (dropped 1291, overlimits 0 requeues 0) backlog 16654b 11p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 7.1ms class fq_codel 10:4e74 parent 10: (dropped 1290, overlimits 0 requeues 0) backlog 6056b 4p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 6.4ms dropping drop_next 92.0ms class fq_codel 10:628a parent 10: (dropped 1289, overlimits 0 requeues 0) backlog 7570b 5p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 5.4ms dropping drop_next 90.9ms class fq_codel 10:a4b3 parent 10: (dropped 302, overlimits 0 requeues 0) backlog 16654b 11p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 7.1ms class fq_codel 10:c3c2 parent 10: (dropped 1284, overlimits 0 requeues 0) backlog 13626b 9p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 5.9ms class fq_codel 10:d331 parent 10: (dropped 299, overlimits 0 requeues 0) backlog 15140b 10p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 7.0ms class fq_codel 10:d526 parent 10: (dropped 12160, overlimits 0 requeues 0) backlog 35870b 211p requeues 0 deficit 1508 count 12160 lastcount 1 ldelay 15.3ms dropping drop_next 247us class fq_codel 10:e2c6 parent 10: (dropped 1288, overlimits 0 requeues 0) backlog 15140b 10p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 7.1ms class fq_codel 10:eab5 parent 10: (dropped 1285, overlimits 0 requeues 0) backlog 16654b 11p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 5.9ms class fq_codel 10:f220 parent 10: (dropped 1289, overlimits 0 requeues 0) backlog 15140b 10p requeues 0 deficit 1514 count 1 lastcount 1 ldelay 7.1ms qdisc htb 1: root refcnt 6 r2q 10 default 1 direct_packets_stat 0 ver 3.17 Sent 43331086547 bytes 33092812 pkt (dropped 0, overlimits 66063544 requeues 71) rate 201697Kbit 28602pps backlog 0b 260p requeues 71 qdisc fq_codel 10: parent 1:1 limit 10240p flows 65536 target 5.0ms interval 100.0ms ecn Sent 43331086547 bytes 33092812 pkt (dropped 949359, overlimits 0 requeues 0) rate 201697Kbit 28602pps backlog 189352b 260p requeues 0 maxpacket 1514 drop_overlimit 0 new_flow_count 5582 ecn_mark 125593 new_flows_len 0 old_flows_len 11 PING 172.30.42.18 (172.30.42.18) 56(84) bytes of data. 64 bytes from 172.30.42.18: icmp_req=1 ttl=64 time=0.227 ms 64 bytes from 172.30.42.18: icmp_req=2 ttl=64 time=0.165 ms 64 bytes from 172.30.42.18: icmp_req=3 ttl=64 time=0.166 ms 64 bytes from 172.30.42.18: icmp_req=4 ttl=64 time=0.151 ms 64 bytes from 172.30.42.18: icmp_req=5 ttl=64 time=0.164 ms 64 bytes from 172.30.42.18: icmp_req=6 ttl=64 time=0.172 ms 64 bytes from 172.30.42.18: icmp_req=7 ttl=64 time=0.175 ms 64 bytes from 172.30.42.18: icmp_req=8 ttl=64 time=0.183 ms 64 bytes from 172.30.42.18: icmp_req=9 ttl=64 time=0.158 ms 64 bytes from 172.30.42.18: icmp_req=10 ttl=64 time=0.200 ms 10 packets transmitted, 10 received, 0% packet loss, time 8999ms rtt min/avg/max/mdev = 0.151/0.176/0.227/0.022 ms Much better than SFQ because of priority given to new flows, and fast path dirtying less cache lines.

2012-05-11batman-adv: avoid temporary routing loops by being strict on forwarded OGMsMarek Lindner
batman-adv would forward OGMs from non-besthops while replacing the the TQ and TTL values with the values from the best hop. In certain corner cases this leads to a temporary routing loop. This patch changes this behavior: Only packets from best next hops are forwarded - TQ and TTL values won't be replaced anymore. However, the protocol needs to rebroadcast OGMs from single hop neighbors regardless of whether or not they are the best hop. To handle this case a new flag is introduced to alert neighboring nodes about the forwarded OGM that is not from my best next hop. It is to be discarded by all nodes except for the one originating the OGM.

2012-05-11batman-adv: Adding hard_iface specific sysfs wrapper macros for UINTLinus Luessing
This allows us to easily add a sysfs parameter for an unsigned int later, which is not for a batman mesh interface (e.g. bat0), but for a common interface instead. It allows reading and writing an atomic_t in hard_iface (instead of bat_priv compared to the mesh variant). Developed by Linus during a 6 months trainee study period in Ascom (Switzerland) AG.
