2011-10-19bridge: fix hang on removal of bridge via netlinkstephen hemminger
Need to cleanup bridge device timers and ports when being bridge device is being removed via netlink. This fixes the problem of observed when doing: ip link add br0 type bridge ip link set dev eth1 master br0 ip link set br0 up ip link del br0 which would cause br0 to hang in unregister_netdev because of leftover reference count.

2011-10-06bridge: leave carrier on for empty bridgestephen hemminger
This resolves a regression seen by some users of bridging. Some users use the bridge like a dummy device. They expect to be able to put an IPv6 address on the device with no ports attached. Although there are better ways of doing this, there is no reason to not allow it. Note: the bridge still will reflect the state of ports in the bridge if there are any added.

2011-08-10Bridge: Always send NETDEV_CHANGEADDR up on br MAC change.Andrei Warkentin
This ensures the neighbor entries associated with the bridge dev are flushed, also invalidating the associated cached L2 headers. This means we br_add_if/br_del_if ports to implement hand-over and not wind up with bridge packets going out with stale MAC. This means we can also change MAC of port device and also not wind up with bridge packets going out with stale MAC. This builds on Stephen Hemminger's patch, also handling the br_del_if case and the port MAC change case.

2011-07-23bridge: send proper message_age in config BPDUstephen hemminger
A bridge topology with three systems: +------+ +------+ | A(2) |--| B(1) | +------+ +------+ \ / +------+ | C(3) | +------+ What is supposed to happen: * bridge with the lowest ID is elected root (for example: B) * C detects that A->C is higher cost path and puts in blocking state What happens. Bridge with lowest id (B) is elected correctly as root and things start out fine initially. But then config BPDU doesn't get transmitted from A -> C. Because of that the link from A-C is transistioned to the forwarding state. The root cause of this is that the configuration messages is generated with bogus message age, and dropped before sending. In the standardmessage_age is supposed to be: the time since the generation of the Configuration BPDU by the Root that instigated the generation of this Configuration BPDU. Reimplement this by recording the timestamp (age + jiffies) when recording config information. The old code incorrectly used the time elapsed on the ageing timer which was incorrect.

As is_multicast_ether_addr returns true on broadcast packets as well, we need to explicitly exclude broadcast packets so that they're always flooded. This wasn't an issue before as broadcast packets were considered to be an unregistered multicast group, which were always flooded.

2011-06-25bridge: Only flood unregistered groups to routersHerbert Xu
The bridge currently floods packets to groups that we have never seen before to all ports. This is not required by RFC4541 and in fact it is not desirable in environment where traffic to unregistered group is always present. This patch changes the behaviour so that we only send traffic to unregistered groups to ports marked as routers. The user can always force flooding behaviour to any given port by marking it as a router. Note that this change does not apply to traffic to 224.0.0.X as traffic to those groups must always be flooded to all ports.

2011-06-17IGMP snooping: set mrouters_only flag for IPv6 traffic properlyFernando Luis Vázquez Cao
Upon reception of a MGM report packet the kernel sets the mrouters_only flag in a skb that is a clone of the original skb, which means that the bridge loses track of MGM packets (cb buffers are tied to a specific skb and not shared) and it ends up forwading join requests to the bridge interface. This can cause unexpected membership timeouts and intermitent/permanent loss of connectivity as described in RFC 4541 [2.1.1. IGMP Forwarding Rules]: A snooping switch should forward IGMP Membership Reports only to those ports where multicast routers are attached. [...] Sending membership reports to other hosts can result, for IGMPv1 and IGMPv2, in unintentionally preventing a host from joining a specific multicast group.

2011-05-02net: dont hold rtnl mutex during netlink dump callbacksEric Dumazet
Four years ago, Patrick made a change to hold rtnl mutex during netlink dump callbacks. I believe it was a wrong move. This slows down concurrent dumps, making good old /proc/net/ files faster than rtnetlink in some situations. This occurred to me because one "ip link show dev ..." was _very_ slow on a workload adding/removing network devices in background. All dump callbacks are able to use RCU locking now, so this patch does roughly a revert of commits : 1c2d670f366 : [RTNETLINK]: Hold rtnl_mutex during netlink dump callbacks 6313c1e0992 : [RTNETLINK]: Remove unnecessary locking in dump callbacks This let writers fight for rtnl mutex and readers going full speed.

2011-04-29ethtool: Use full 32 bit speed range in ethtool's set_settingsDavid Decotigny
This makes sure the ethtool's set_settings() callback of network drivers don't ignore the 16 most significant bits when ethtool calls their set_settings(). All drivers compiled with make allyesconfig on x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-04-22Revert "bridge: Forward reserved group addresses if !STP"David S. Miller
This reverts commit 1e253c3b8a1aeed51eef6fc366812f219b97de65. It breaks 802.3ad bonding inside of a bridge. The commit was meant to support transport bridging, and specifically virtual machines bridged to an ethernet interface connected to a switch port wiht 802.1x enabled. But this isn't the way to do it, it breaks too many other things. Signed-off-by: David S. Miller <davem@davemloft.net>
