2009-03-26netfilter: fix warning about invalid const usageEric Leblond
This patch fixes the declaration of the logger structure in ebt_log and ebt_ulog: I forgot to remove the const option from their declaration in the commit ca735b3aaa945626ba65a3e51145bfe4ecd9e222 ("netfilter: use a linked list of loggers").

2009-03-25bonding: select current active slave when enslaving device for mode tlb and albJiri Pirko
I've hit an issue on my system when I've been using RealTek RTL8139D cards in bonding interface in mode balancing-alb. When I enslave a card, the current active slave (bond->curr_active_slave) is not set and the link is therefore not functional. ---- # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.5.0 (November 4, 2008) Bonding Mode: adaptive load balancing Primary Slave: None Currently Active Slave: None MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:1f:1f:01:2f:22 ---- The thing that gets it right is when I unplug the cable and then I put it back into the NIC. Then the current active slave is set to eth1 and link is working just fine. Here is dmesg log with bonding DEBUG messages turned on: ---- ADDRCONF(NETDEV_UP): bond0: link is not ready event_dev: bond0, event: 1 IFF_MASTER event_dev: bond0, event: 8 IFF_MASTER bond_ioctl: master=bond0, cmd=35216 slave_dev=cac5d800: slave_dev->name=eth1: eth1: !

I also tested this on other machine with Broadcom NetXtreme II BCM5708 1000Base-T NIC and there all works fine. The thing is that this adapter is down and goes up after few seconds after it is enslaved. This patch calls bond_select_active_slave() in bond_enslave() function for modes alb and tlb and makes sure that the current active slave is set up properly even when the slave state is already up. Tested on both systems, works fine. Notice: The same problem can maybe also occrur in mode 8023AD but I'm unable to test that. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

2009-03-24ipv6: Fix conflict resolutions during ipv6 bindingVlad Yasevich

2009-03-24ipv6: Make v4-mapped bindings consistent with IPv4Vlad Yasevich
Binding to a v4-mapped address on an AF_INET6 socket should produce the same result as binding to an IPv4 address on AF_INET socket.

2009-03-24ipv6: Allow ipv4 wildcard binds after ipv6 address bindsVlad Yasevich
The IPv4 wildcard (0.0.0.0) address does not intersect in any way with explicit IPv6 addresses. These two should be permitted, but the IPv4 conflict code checks the ipv6only bit as part of the test. Since binding to an explicit IPv6 address restricts the socket to only that IPv6 address, the side-effect is that the socket behaves as v6-only. By explicitely setting ipv6only in this case, allows the 2 binds to succeed. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-24ipv6: Disallow binding to v4-mapped address on v6-only socket.Vlad Yasevich

2009-03-24netlink: add NETLINK_NO_ENOBUFS socket flagPablo Neira Ayuso
This patch adds the NETLINK_NO_ENOBUFS socket flag. This flag can be used by unicast and broadcast listeners to avoid receiving ENOBUFS errors. Generally speaking, ENOBUFS errors are useful to notify two things to the listener: a) You may increase the receiver buffer size via setsockopt(). b) You have lost messages, you may be out of sync. In some cases, ignoring ENOBUFS errors can be useful. For example: a) nfnetlink_queue: this subsystem does not have any sort of resync method and you can decide to ignore ENOBUFS once you have set a given buffer size. b) ctnetlink: you can use this together with the socket flag NETLINK_BROADCAST_SEND_ERROR to stop getting ENOBUFS errors as you do not need to resync (packets whose event are not delivered are drop to provide reliable logging and state-synchronization). Moreover, the use of NETLINK_NO_ENOBUFS also reduces a "go up, go down" effect in terms of performance which is due to the netlink congestion control when the listener cannot back off. The effect is the following: 1) throughput rate goes up and netlink messages are inserted in the receiver buffer. 2) Then, netlink buffer fills and overruns (set on nlk->state bit 0). 3) While the listener empties the receiver buffer, netlink keeps dropping messages. Thus, throughput goes dramatically down. 4) Then, once the listener has emptied the buffer (nlk->state bit 0 is set off), goto step 1. This effect is easy to trigger with netlink broadcast under heavy load, and it is more noticeable when using a big receiver buffer. You can find some results in [1] that show this problem. [1] http://1984.lsi.us.es/linux/netlink/ This patch also includes the use of sk_drop to account the number of netlink messages drop due to overrun. This value is shown in /proc/net/netlink.

We use RCU to defer freeing of conntrack structures. In DOS situation, RCU might accumulate about 10.000 elements per CPU in its internal queues. To get accurate conntrack counts (at the expense of slightly more RAM used), we might consider conntrack counter not taking into account "about to be freed elements, waiting in RCU queues". We thus decrement it in nf_conntrack_free(), not in the RCU callback.
