Revert "bridge: Forward reserved group addresses if !STP"

2011-04-22T04:17:25+00:00

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.

net: introduce rx_handler results and logic around that

2011-03-16T19:53:54+00:00

This patch allows rx_handlers to better signalize what to do next to
it's caller. That makes skb->deliver_no_wcard no longer needed.

kernel-doc for rx_handler_result is taken from Nicolas' patch.

bridge: Replace mp->mglist hlist with a bool

2011-02-12T09:05:42+00:00

As it turns out we never need to walk through the list of multicast
groups subscribed by the bridge interface itself (the only time we'd
want to do that is when we shut down the bridge, in which case we
simply walk through all multicast groups), we don't really need to
keep an hlist for mp->mglist.

This means that we can replace it with just a single bit to indicate
whether the bridge interface is subscribed to a group.

bridge: add proper RCU annotation to should_route_hook

2010-11-15T19:13:16+00:00

Add br_should_route_hook_t typedef, this is the only way we can
get a clean RCU implementation for function pointer.

Move route_hook to location where it is used.

bridge: Forward reserved group addresses if !STP

2010-10-21T11:25:48+00:00

Make all frames sent to reserved group MAC addresses (01:80:c2:00:00:00 to
01:80:c2:00:00:0f) be forwarded if STP is disabled. This enables
forwarding EAPOL frames, among other things.

bridge: is PACKET_LOOPBACK unlikely()?

2010-08-23T04:09:04+00:00

While looking at using netdev_rx_handler_register for openvswitch Jesse
Gross suggested that an unlikely() might be worthwhile in that code.
I'm interested to see if its appropriate for the bridge code.

bridge: add rcu_read_lock on transmit

2010-07-28T17:50:55+00:00

Long ago, when bridge was converted to RCU, rcu lock was equivalent
to having preempt disabled. RCU has changed a lot since then and
bridge code was still assuming the since transmit was called with
bottom half disabled, it was RCU safe.

bridge: 64bit rx/tx counters

2010-06-23T20:00:48+00:00

Use u64_stats_sync infrastructure to provide 64bit rx/tx
counters even on 32bit hosts.

It is safe to use a single u64_stats_sync for rx and tx,
because BH is disabled on both, and we use per_cpu data.

bridge: use rx_handler_data pointer to store net_bridge_port pointer

2010-06-15T18:48:58+00:00

Register net_bridge_port pointer as rx_handler data pointer. As br_port is
removed from struct net_device, another netdev priv_flag is added to indicate
the device serves as a bridge port. Also rcuized pointers are now correctly
dereferenced in br_fdb.c and in netfilter parts.
