This patch allows the user to control the hash elasticity/max parameters. The elasticity setting does not take effect until the next new multicast group is added. At which point it is checked and if after rehashing it still can't be satisfied then snooping will be disabled. The max setting on the other hand takes effect immediately. It must be a power of two and cannot be set to a value less than the current number of multicast group entries. This is the only way to shrink the multicast hash. Signed-off-by:

This patch allows the user to disable IGMP snooping completely through a sysfs toggle. It also allows the user to reenable snooping when it has been automatically disabled due to hash collisions. If the collisions have not been resolved however the system will refuse to reenable snooping. Signed-off-by:

This patch allows the user to forcibly enable/disable ports as having multicast routers attached. A port with a multicast router will receive all multicast traffic. The value 0 disables it completely. The default is 1 which lets the system automatically detect the presence of routers (currently this is limited to picking up queries), and 2 means that the port will always receive all multicast traffic.

This patch finally hooks up the multicast snooping module to the data path. In particular, all multicast packets passing through the bridge are fed into the module and switched by it. Signed-off-by:

This patch adds code to perform selective multicast forwarding. We forward multicast traffic to a set of ports plus all multicast router ports. In order to avoid duplications among these two sets of ports, we order all ports by the numeric value of their pointers. The two lists are then walked in lock-step to eliminate duplicates.

This patch adds the core functionality of IGMP snooping support without actually hooking it up. So this patch should be a no-op as far as the bridge's external behaviour is concerned. All the new code and data is controlled by the Kconfig option BRIDGE_IGMP_SNOOPING. A run-time toggle is also available. The multicast switching is done using an hash table that is lockless on the read-side through RCU. On the write-side the new multicast_lock is used for all operations. The hash table supports dynamic growth/rehashing. The hash table will be rehashed if any chain length exceeds a preset limit. If rehashing does not reduce the maximum chain length then snooping will be disabled. These features may be added in future (in no particular order): * IGMPv3 source support * Non-querier router detection * IPv6 Signed-off-by:

This patch moves the main loop body in br_flood into the function may_deliver. The code that clones an skb and delivers it is moved into the deliver_clone function. This allows this to be reused by the future multicast forward function. Signed-off-by:

this patch makes BR_INPUT_SKB_CB available on the xmit path so that we could avoid passing the br pointer around for the purpose of collecting device statistics. Signed-off-by:
-
Herbert Xu authored
When the packet is delivered to the local bridge device we may end up cloning it unnecessarily if no bridge port can receive the packet in br_flood. This patch avoids this by moving the skb_clone into br_flood. Signed-off-by:

This patch allows tail-call on the call to br_pass_frame_up in br_handle_frame_finish. This is now possible because of the previous patch to call br_pass_frame_up last. Signed-off-by:
-
Herbert Xu authored
At the moment we deliver to the local bridge port via the function br_pass_frame_up before all other ports. There is no requirement for this. For the purpose of IGMP snooping, it would be more convenient if we did the local port last. Therefore this patch rearranges the bridge input processing so that the local bridge port gets to see the packet last (if at all). Signed-off-by:

With the Bluetooth 3.0 specification and the introduction of alternate MAC/PHY (AMP) support, it is required to differentiate between primary BR/EDR controllers and 802.11 AMP controllers. So introduce a special type inside HCI device for differentiation. For now all AMP controllers will be treated as raw devices until an AMP manager has been implemented. Signed-off-by: -

Move TC_PRIO_CONTROL check and queue remapping into ixgbe_select_queue(). Remapping queues after the qdisc can result in the wrong qdisc queue being stopped with netif_stop_subqueue(). Even if this is resolved and the correct queue is stopped it can result in a queue being blocked by TC_PRIO_CONTROL frames uneccesarily. Moving this into the select_queue routine maintains alignment between tx_rings and qdisc queues. Signed-off-by:

The alignment requirement for 64-bit load/store instructions on ARM is implementation defined. Some CPUs (such as Marvell Feroceon) do not generate an exception, if such an instruction is executed with an address that is not 64 bit aligned. In such a case, the Feroceon corrupts adjacent memory, which showed up in my tests as a crash in the rx path of ath9k that only occured with CONFIG_XFRM set. This crash happened, because the first field of the mac80211 rx status info in the cb is an u64, and changing it corrupted the skb->sp field. This patch also closes some potential pre-existing holes in the sk_buff struct surrounding the cb[] area. Signed-off-by:

commit e8469ed959c373c2ff9e6f488aa5a14971aebe1f Author: Patrick McHardy <kaber@trash.net> Date: Tue Feb 23 20:41:30 2010 +0100 Support specifying the initial device flags when creating a device though rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING in order to surpress netlink registration notifications. To complete setup, rtnl_configure_link() must be called, which performs the device flag changes and invokes the deferred notifiers if everything went well. Two examples: # add macvlan to eth0 # $ ip link add link eth0 up allmulticast on type macvlan [LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 26:f8:84:02:f9:2a brd ff:ff:ff:ff:ff:ff [ROUTE]ff00::/8 dev macvlan0 table local metric 256 mtu 1500 advmss 1440 hoplimit 0 [ROUTE]fe80::/64 dev macvlan0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 0 [LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 link/ether 26:f8:84:02:f9:2a [ADDR]11: macvlan0 inet6 fe80::24f8:84ff:fe02:f92a/64 scope link valid_lft forever preferred_lft forever [ROUTE]local fe80::24f8:84ff:fe02:f92a via :: dev lo table local proto none metric 0 mtu 16436 advmss 16376 hoplimit 0 [ROUTE]default via fe80::215:e9ff:fef0:10f8 dev macvlan0 proto kernel metric 1024 mtu 1500 advmss 1440 hoplimit 0 [NEIGH]fe80::215:e9ff:fef0:10f8 dev macvlan0 lladdr 00:15:e9:f0:10:f8 router STALE [ROUTE]2001:6f8:974::/64 dev macvlan0 proto kernel metric 256 expires 0sec mtu 1500 advmss 1440 hoplimit 0 [PREFIX]prefix 2001:6f8:974::/64 dev macvlan0 onlink autoconf valid 14400 preferred 131084 [ADDR]11: macvlan0 inet6 2001:6f8:974:0:24f8:84ff:fe02:f92a/64 scope global dynamic valid_lft 86399sec preferred_lft 14399sec # add VLAN to eth1, eth1 is down # $ ip link add link eth1 up type vlan id 1000 RTNETLINK answers: Network is down <no events> Signed-off-by: -

Split dev_change_flags() into two functions: __dev_change_flags() to perform the actual changes and __dev_notify_flags() to invoke netdevice notifiers. This will be used by rtnl_link to defer netlink notifications until the device has been fully configured. This changes ordering of some operations, in particular: - netlink notifications are sent after all changes have been performed. As a side effect this surpresses one unnecessary netlink message when the IFF_UP and other flags are changed simultaneously. - The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked after all changes have been performed. Their relative is unchanged. - net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead of afterwards. This should not make any difference since both RX and TX are already shut down at this point. Signed-off-by:

In order to support specifying device flags during device creation, we must be able to roll back device registration in case setting the flags fails without sending any notifications related to the device to userspace. This patch changes rollback_registered_many() and register_netdevice() to manually send netlink notifications for devices not handled by rtnl_link and allows to defer notifications for devices handled by rtnl_link until setup is complete.

Commit 3b8bcfd5 (net: introduce pre-up netdev notifier) added a new notifier which is run before a device is set UP for use by cfg80211. The patch missed to add the new notifier to the ignore list in rtnetlink_event(), so we currently get an unnecessary netlink notification before a device is set UP. Signed-off-by:
