bridge: Have tx_bytes count headers like rx_bytes. Since rx_bytes accounting does not include Ethernet Headers in br_input.c, excluding ETH_HLEN on the transmit path for consistent measurement of packet length on both the Tx and Rx chains. The clean way would be for Rx to include the eth header, but the skb len has already been adjusted by the time the br code sees the skb. This is only a temporary workaround until we can completely ignore or cleanly fix the skb->len handling.

bridge: Add filtering support for default_pvid Currently when vlan filtering is turned on on the bridge, the bridge will drop all traffic untill the user configures the filter. This isn't very nice for ports that don't care about vlans and just want untagged traffic. A concept of a default_pvid was recently introduced. This patch adds filtering support for default_pvid. Now, ports that don't care about vlans and don't define there own filter will belong to the VLAN of the default_pvid and continue to receive untagged traffic. This filtering can be disabled by setting default_pvid to 0. Signed-off-by: Vladislav Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

netfilter: bridge: move br_netfilter out of the core Jesper reported that br_netfilter always registers the hooks since this is part of the bridge core. This harms performance for people that don't need this. This patch modularizes br_netfilter so it can be rmmod'ed, thus, the hooks can be unregistered. I think the bridge netfilter should have been a separated module since the beginning, Patrick agreed on that. Note that this is breaking compatibility for users that expect that bridge netfilter is going to be available after explicitly 'modprobe bridge' or via automatic load through brctl. However, the damage can be easily undone by modprobing br_netfilter. The bridge core also spots a message to provide a clue to people that didn't notice that this has been deprecated. On top of that, the plan is that nftables will not rely on this software layer, but integrate the connection tracking into the bridge layer to enable stateful filtering and NAT, which is was bridge netfilter users seem to require. This patch still keeps the fake_dst_ops in the bridge core, since this is required by when the bridge port is initialized. So we can safely modprobe/rmmod br_netfilter anytime.

As user might not want group_fwd_mask to be modified by enabling 802.1ad, introduce a new mask, group_fwd_mask_required, which indicates addresses the bridge wants to forward.

bridge: Automatically manage port promiscuous mode. There exist configurations where the administrator or another management entity has the foreknowledge of all the mac addresses of end systems that are being bridged together. In these environments, the administrator can statically configure known addresses in the bridge FDB and disable flooding and learning on ports. This makes it possible to turn off promiscuous mode on the interfaces connected to the bridge. Here is why disabling flooding and learning allows us to control promiscuity: Consider port X. All traffic coming into this port from outside the bridge (ingress) will be either forwarded through other ports of the bridge (egress) or dropped. Forwarding (egress) is defined by FDB entries and by flooding in the event that no FDB entry exists. In the event that flooding is disabled, only FDB entries define the egress. Once learning is disabled, only static FDB entries provided by a management entity define the egress. If we provide information from these static FDBs to the ingress port X, then we'll be able to accept all traffic that can be successfully forwarded and drop all the other traffic sooner without spending CPU cycles to process it. Another way to define the above is as following equations: ingress = egress + drop expanding egress ingress = static FDB + learned FDB + flooding + drop disabling flooding and learning we a left with ingress = static FDB + drop By adding addresses from the static FDB entries to the MAC address filter of an ingress port X, we fully define what the bridge can process without dropping and can thus turn off promiscuous mode, thus dropping packets sooner. There have been suggestions that we may want to allow learning and update the filters with learned addresses as well. This would require mac-level authentication similar to 802.1x to prevent attacks against the hw filters as they are limited resource. Additionally, if the user places the bridge device in promiscuous mode, all ports are placed in promiscuous mode regardless of the changes to flooding and learning. Since the above functionality depends on full static configuration, we have also require that vlan filtering be enabled to take advantage of this. The reason is that the bridge has to be able to receive and process VLAN-tagged frames and the there are only 2 ways to accomplish this right now: promiscuous mode or vlan filtering.

bridge: Change local fdb entries whenever mac address of bridge device changes Vlan code may need fdb change when changing mac address of bridge device even if it is caused by the mac address changing of a bridge port. Example configuration: ip link set eth0 address 12:34:56:78:90:ab ip link set eth1 address aa:bb:cc:dd:ee:ff brctl addif br0 eth0 brctl addif br0 eth1 # br0 will have mac address 12:34:56:78:90:ab bridge vlan add dev br0 vid 10 self bridge vlan add dev eth0 vid 10 We will have fdb entry such that f->dst == NULL, f->vlan_id == 10 and f->addr == 12:34:56:78:90:ab at this time. Next, change the mac address of eth0 to greater value. ip link set eth0 address ee:ff:12:34:56:78 Then, mac address of br0 will be recalculated and set to aa:bb:cc:dd:ee:ff. However, an entry aa:bb:cc:dd:ee:ff will not be created and we will be not able to communicate using br0 on vlan 10. Address this issue by deleting and adding local entries whenever changing the mac address of the bridge device. If there already exists an entry that has the same address, for example, in case that br_fdb_changeaddr() has already inserted it, br_fdb_change_mac_address() will simply fail to insert it and no duplicated entry will be made, as it was. This approach also needs br_add_if() to call br_fdb_insert() before br_stp_recalculate_bridge_id() so that we don't create an entry whose dst == NULL in this function to preserve previous behavior. Note that this is a slight change in behavior where the bridge device can receive the traffic to the new address before calling br_stp_recalculate_bridge_id() in br_add_if(). However, it is not a problem because we have already the address on the new port and such a way to insert new one before recalculating bridge id is taken in br_device_event() as well.

net: Explicitly initialize u64_stats_sync structures for lockdep In order to enable lockdep on seqcount/seqlock structures, we must explicitly initialize any locks. The u64_stats_sync structure, uses a seqcount, and thus we need to introduce a u64_stats_init() function and use it to initialize the structure. This unfortunately adds a lot of fairly trivial initialization code to a number of drivers. But the benefit of ensuring correctness makes this worth while. Because these changes are required for lockdep to be enabled, and the changes are quite trivial, I've not yet split this patch out into 30-some separate patches, as I figured it would be better to get the various maintainers thoughts on how to best merge this change along with the seqcount lockdep enablement.

bridge: separate querier and query timer into IGMP/IPv4 and MLD/IPv6 ones Currently we would still potentially suffer multicast packet loss if there is just either an IGMP or an MLD querier: For the former case, we would possibly drop IPv6 multicast packets, for the latter IPv4 ones. This is because we are currently assuming that if either an IGMP or MLD querier is present that the other one is present, too. This patch makes the behaviour and fix added in "bridge: disable snooping if there is no querier" (b00589af3b04) to also work if there is either just an IGMP or an MLD querier on the link: It refines the deactivation of the snooping to be protocol specific by using separate timers for the snooped IGMP and MLD queries as well as separate timers for our internal IGMP and MLD queriers.

These lost multicast packets can appear since c5c23260594 ("bridge: Add multicast_querier toggle and disable queries by default") in particular. With this patch we are flooding multicast packets if our querier is disabled and if we didn't detect any other querier. A grace period of the Maximum Response Delay of the querier is added to give multicast responses enough time to arrive and to be learned from before disabling the flooding behaviour again.

netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lock __netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is already held. The mechanism is used to asynchronously call __netpoll_cleanup outside of the holding of the rtnl_lock, so as to avoid deadlock. Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the rtnl_lock must be held while calling it. Further, it cannot be held, because rcu callbacks may be issued in softirq contexts, which cannot sleep. Fix this by converting the rcu callback to a work queue that is guaranteed to get scheduled in process context, so that we can hold the rtnl properly while calling __netpoll_cleanup Tested successfully by myself.

net, ixgbe: handle link local multicast addresses in SR-IOV mode In SR-IOV mode the PF driver acts as the uplink port and is used to send control packets e.g. lldpad, stp, etc. eth0.1 eth0.2 eth0 VF VF PF | | | <-- stand-in for uplink | | | -------------------------- | Embedded Switch | -------------------------- | MAC <-- uplink But the embedded switch is setup to forward multicast addresses to all interfaces both VFs and PF and onto the physical link. This results in reserved MAC addresses used by control protocols to be forwarded over the switch onto the VF. In the LLDP case the PF sends an LLDPDU and it is currently being forwarded to all the VFs who then see the PF as a peer. This is incorrect. This patch adds the multicast addresses to the RAR table in the hardware to prevent this behavior.

net: add generic PF_BRIDGE:RTM_ FDB hooks This adds two new flags NTF_MASTER and NTF_SELF that can now be used to specify where PF_BRIDGE netlink commands should be sent. NTF_MASTER sends the commands to the 'dev->master' device for parsing. Typically this will be the linux net/bridge, or open-vswitch devices. Also without any flags set the command will be handled by the master device as well so that current user space tools continue to work as expected. The NTF_SELF flag will push the PF_BRIDGE commands to the device. In the basic example below the commands are then parsed and programmed in the embedded bridge. Note if both NTF_SELF and NTF_MASTER bits are set then the command will be sent to both 'dev->master' and 'dev' this allows user space to easily keep the embedded bridge and software bridge in sync. There is a slight complication in the case with both flags set when an error occurs. To resolve this the rtnl handler clears the NTF_ flag in the netlink ack to indicate which sets completed successfully. The add/del handlers will abort as soon as any error occurs. To support this new net device ops were added to call into the device and the existing bridging code was refactored to use these. There should be no required changes in user space to support the current bridge behavior. A basic setup with a SR-IOV enabled NIC looks like this, veth0 veth2 | | ------------ | bridge0 | <---- software bridging ------------ / / ethx.y ethx VF PF \ \ <---- propagate FDB entries to HW \ \ -------------------- | Embedded Bridge | <---- hardware offloaded switching -------------------- In this case the embedded bridge must be managed to allow 'veth0' to communicate with 'ethx.y' correctly. At present drivers managing the embedded bridge either send frames onto the network which then get dropped by the switch OR the embedded bridge will flood these frames. With this patch we have a mechanism to manage the embedded bridge correctly from user space. This example is specific to SR-IOV but replacing the VF with another PF or dropping this into the DSA framework generates similar management issues. Examples session using the 'br'[1] tool to add, dump and then delete a mac address with a new "embedded" option and enabled ixgbe driver: # br fdb add 22:35:19:ac:60:59 dev eth3 # br fdb port mac addr flags veth0 22:35:19:ac:60:58 static veth0 9a:5f:81:f7:f6:ec local eth3 00:1b:21:55:23:59 local eth3 22:35:19:ac:60:59 static veth0 22:35:19:ac:60:57 static #br fdb add 22:35:19:ac:60:59 embedded dev eth3 #br fdb port mac addr flags veth0 22:35:19:ac:60:58 static veth0 9a:5f:81:f7:f6:ec local eth3 00:1b:21:55:23:59 local eth3 22:35:19:ac:60:59 static veth0 22:35:19:ac:60:57 static eth3 22:35:19:ac:60:59 local embedded #br fdb del 22:35:19:ac:60:59 embedded dev eth3 I added a couple lines to 'br' to set the flags correctly is all. It is my opinion that the merit of this patch is now embedded and SW bridges can both be modeled correctly in user space using very nearly the same message passing.

bridge: allow forwarding some link local frames This is based on an earlier patch by Nick Carter with comments by David Lamparter but with some refinements. Thanks for their patience this is a confusing area with overlap of standards, user requirements, and compatibility with earlier releases. It adds a new sysfs attribute /sys/class/net/brX/bridge/group_fwd_mask that controls forwarding of frames with address of: 01-80-C2-00-00-0X The default setting has no forwarding to retain compatibility. One change from earlier releases is that forwarding of group addresses is not dependent on STP being enabled or disabled. This choice was made based on interpretation of tie 802.1 standards. I expect complaints will arise because of this, but better to follow the standard than continue acting incorrectly by default. The filtering mask is writeable, but only values that don't forward known control frames are allowed. It intentionally blocks attempts to filter control protocols. For example: writing a 8 allows forwarding 802.1X PAE addresses which is the most common request.

Example: # ip link add link dev br0 type bridge # ip link del dev br0 The change required rearranging initializtion code to deal with being called by create link. Most of the initialization happens in br_dev_setup, but allocation of stats is done in ndo_init callback to deal with allocation failure.

bridge: control carrier based on ports online This makes the bridge device behave like a physical device. In earlier releases the bridge always asserted carrier. This changes the behavior so that bridge device carrier is on only if one or more ports are in the forwarding state. This should help IPv6 autoconfiguration, DHCP, and routing daemons. I did brief testing with Network and Virt manager and they seem fine, but since this changes behavior of bridge, it should wait until net-next (2.6.39).

We can make the _metrics member a pointer instead of an array, initially have it point at the read-only metrics in the FIB, and then on the first set grab an inetpeer entry and point the _metrics member there.

bridge: Partially disable netpoll support The new netpoll code in bridging contains use-after-free bugs that are non-trivial to fix. This patch fixes this by removing the code that uses skbs after they're freed. As a consequence, this means that we can no longer call bridge from the netpoll path, so this patch also removes the controller function in order to disable netpoll.

net: fix 64 bit counters on 32 bit arches There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.

bridge: Fix netpoll support There are multiple problems with the newly added netpoll support: 1) Use-after-free on each netpoll packet. 2) Invoking unsafe code on netpoll/IRQ path. 3) Breaks when netpoll is enabled on the underlying device. This patch fixes all of these problems. In particular, we now allocate proper netpoll structures for each underlying device. We only allow netpoll to be enabled on the bridge when all the devices underneath it support netpoll. Once it is enabled, we do not allow non-netpoll devices to join the bridge (until netpoll is disabled again). This allows us to do away with the npinfo juggling that caused problem number 1. Incidentally this patch fixes number 2 by bypassing unsafe code such as multicast snooping and netfilter.

So what happened was that it would simply take the TSO status of the last constituent device. This patch extends it to support both conjunctions and disjunctions under the new name of netdev_increment_features. It also adds a new function netdev_fix_features which does the sanity checking that usually occurs upon registration. This ensures that the computation doesn't result in an illegal combination since this checking is absent when the change is initiated via ethtool.

bridge: send correct MTU value in PMTU (revised) When bridging interfaces with different MTUs, the bridge correctly chooses the minimum of the MTUs of the physical devices as the bridges MTU. But when a frame is passed which fits through the incoming, but not through the outgoing interface, a "Fragmentation Needed" packet is generated. However, the propagated MTU is hardcoded to 1500, which is wrong in this situation. The sender will repeat the packet again with the same frame size, and the same problem will occur again. Instead of sending 1500, the (correct) MTU value of the bridge is now sent via PMTU. To achieve this, the corresponding rtable structure is stored in its net_bridge structure.

[NET]: Share correct feature code between bridging and bonding http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the bonding driver may produce bogus combinations of the checksum flags and SG/TSO. For example, if you bond devices with NETIF_F_HW_CSUM and NETIF_F_IP_CSUM you'll end up with a bonding device that has neither flag set. If both have TSO then this produces an illegal combination. The bridge device on the other hand has the correct code to deal with this. In fact, the same code can be used for both. So this patch moves that logic into net/core/dev.c and uses it for both bonding and bridging. In the process I've made small adjustments such as only setting GSO_ROBUST if at least one constituent device supports it.

Packets with this bit set can only be fed directly to devices with the corresponding bit NETIF_F_GSO_ROBUST. If the device doesn't have that bit, then the skb is fed to the GSO engine which will allow the packet to be sent to the hardware if it passes the header check. This patch changes the sg flag to a full features flag. The same method can be used to implement TSO ECN support. We simply have to mark packets with CWR set with SKB_GSO_ECN so that only hardware with a corresponding NETIF_F_TSO_ECN can accept them. The GSO engine can either fully segment the packet, or segment the first MTU and pass the rest to the hardware for further segmentation.

[BRIDGE]: Add support for NETIF_F_HW_CSUM devices As it is the bridge will only ever declare NETIF_F_IP_CSUM even if all its constituent devices support NETIF_F_HW_CSUM. This patch fixes this by supporting the first one out of NETIF_F_NO_CSUM, NETIF_F_HW_CSUM, and NETIF_F_IP_CSUM that is supported by all constituent devices.

[BRIDGE]: forwarding remove unneeded preempt and bh diasables Optimize the forwarding and transmit paths. Both places are called with bottom half/no preempt so there is no need to use spin_lock_bh or rcu_read_lock. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.

[BRIDGE]: limited ethtool support Add limited ethtool support to bridge to allow disabling features. Note: if underlying device does not support a feature (like checksum offload), then the bridge device won't inherit it. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.

[BRIDGE]: allow setting hardware address of bridge pseudo-dev Some people are using bridging to hide multiple machines from an ISP that restricts by MAC address. So in that case allow the bridge mac address to be set to any of the existing interfaces. I don't want to allow any arbitrary value and confuse STP.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
