* bridge: Fix double-free in br_add_if.Jeff Hansen2009-09-281-0/+1
| | | | | | | | | | | | There is a potential double-kfree in net/bridge/br_if.c. If br_fdb_insert fails, then the kobject is put back (which calls kfree due to the kobject release), and then kfree is called again on the net_bridge_port. This patch fixes the crash. Thanks to Stephen Hemminger for the one-line fix. Signed-off-by: Jeff Hansen <x@jeffhansen.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* net: Add DEVTYPE support for Ethernet based devicesMarcel Holtmann2009-09-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ethernet framing is used for a lot of devices these days. Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.

* | net/bridge: Add 'hairpin' port forwarding modeFischer, Anna2009-08-134-1/+23
|/ | | | | | | | | | | | | | | | | | | | | | | This patch adds a 'hairpin' (also called 'reflective relay') mode port configuration to the Linux Ethernet bridge kernel module. A bridge supporting hairpin forwarding mode can send frames back out through the port the frame was received on. Hairpin mode is required to support basic VEPA (Virtual Ethernet Port Aggregator) capabilities. You can find additional information on VEPA here: http://tech.groups.yahoo.com/group/evb/ http://www.ieee802.org/1/files/public/docs2009/new-hudson-vepa_seminar-20090514d.pdf http://www.internet2.edu/presentations/jt2009jul/20090719-congdon.pdf An additional patch 'bridge-utils: Add 'hairpin' port forwarding mode' is provided to allow configuring hairpin mode from userspace tools.

* | bridge: fix initial packet flood if !STPStephen Hemminger2009-05-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If bridge is configured with no STP and forwarding delay of 0 (which is typical for virtualization) then when link starts it will flood all packets for the first 20 seconds. This bug was introduced by a combination of earlier changes: * forwarding database uses hold time of zero to indicate user wants to always flood packets * optimzation of the case of forwarding delay of 0 avoids the initial timer tick The fix is to just skip all the topology change detection code if kernel STP is not being used.

* | bridge: relay bridge multicast pkgs if !STPStephen Hemminger2009-05-171-0/+5
|/ | | | | | | | | | | | | | | | Currently the bridge catches all STP packets; even if STP is turned off. This prevents other systems (which do have STP turned on) from being able to detect loops in the network. With this patch, if STP is off, then any packet sent to the STP multicast group address is forwarded to all ports. Based on earlier patch by Joakim Tjernlund with changes to go through forwarding (not local chain), and optimization that only last octet needs to be checked.

| | | | | | | | | | | | | | | | | | | | | | | | This fixes an crash when empty bond device is added to a bridge. If an interface with invalid ethernet address (all zero) is added to a bridge, then bridge code detects it when setting up the forward databas entry. But the error unwind is broken, the bridge port object can get freed twice: once when ref count went to zeo, and once by kfree. Since object is never really accessible, just free it.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

* netfilter 03/09: bridge: Disable PPPOE/VLAN processing by defaultHerbert Xu2009-01-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | The PPPOE/VLAN processing code in the bridge netfilter is broken by design. The VLAN tag and the PPPOE session ID are an integral part of the packet flow information, yet they're completely ignored by the bridge netfilter. This is potentially a security hole as it treats all VLANs and PPPOE sessions as the same. What's more, it's actually broken for PPPOE as the bridge netfilter tries to trim the packets to the IP length without adjusting the PPPOE header (and adjusting the PPPOE header isn't much better since the PPPOE peer may require the padding to be present). Therefore we should disable this by default. It does mean that people relying on this feature may lose networking depending on how their bridge netfilter rules are configured. However, IMHO the problems this code causes are serious enough to warrant this.

* netfilter 02/09: bridge: Fix handling of non-IP packets in FORWARD/POST_ROUTINGHerbert Xu2009-01-121-2/+8
| | | | | | | | | | Currently the bridge FORWARD/POST_ROUTING chains treats all non-IPv4 packets as IPv6. This packet fixes that by returning NF_ACCEPT on non-IP packets instead, just as is done in PRE_ROUTING.

* net/bridge/netfilter: move a dereference below a NULL testJulia Lawall2009-01-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S.
