In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE message, then a route is searched as if a packet was received on the specified 'iif' interface. However in IPv6, RTA_IIF is not interpreted in the same way: 'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the RTA_IIF attribute. As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look for a route as if a packet was received on a specific interface. Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a route as if a packet was received on the specified interface", similar to IPv4's 'inet_rtm_getroute()' interpretation.

If both addresses equal, nothing needs to be done. If the device is down, then we simply copy the new address to dev->dev_addr. If the device is up, then we add another loopback device with the new address, and if that does not fail, we remove the loopback device with the old address. And only then, we update the dev->dev_addr. Signed-off-by: NDaniel Borkmann <daniel.borkmann@tik.ee.ethz.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

An infinite loop occurred if garp_attr_create was called with the values of an existing attribute. This might happen if a previous leave request for the attribute has not yet been followed by a PDU transmission (or, if the application previously issued a join request for the attribute and is now issuing another one, without having issued a leave request). If garp_attr_create finds an existing attribute having the same values, return the address to it. Its state will then get updated (i.e., if it was in a leaving state, it will move into a non-leaving state and not get deleted during the next PDU transmission). To accomplish this fix, collapse garp_attr_insert into garp_attr_create (which is its only caller). Thanks to Jorge Boncompte [DTI2] <jorge@dti2.net> for contributing to this fix.

When a bonding device is configured with fail_over_mac=active, we expect to see the MAC address of the new active slave as the source MAC address after failover. But we see that the source MAC address is the MAC address of previous active slave. Emit NETDEV_CHANGEADDR event when bonding changes its MAC address, in order to let arp_netdev_event flush neighbour cache and route cache. How to reproduce this bug ? -----------hostB---------------- hostA ----- switch ---|-- eth0--bond0(192.168.100.2/24)| (192.168.100.1/24 \--|-- eth1-/ | -------------------------------- 1 on hostB, modprobe bonding mode=1 miimon=500 fail_over_mac=active downdelay=1000 num_grat_arp=1 ifconfig bond0 192.168.100.2/24 up ifenslave bond0 eth0 ifenslave bond0 eth1 then eth0 is the active slave, and MAC of bond0 is MAC of eth0. 2 on hostA, ping 192.168.100.2 3 on hostB, tcpdump -i bond0 -p icmp -XXX you will see bond0 uses MAC of eth0 as source MAC in icmp reply. 4 on hostB, ifconfig eth0 down tcpdump -i bond0 -p icmp -XXX (just keep it running in step 3) you will see first bond0 uses MAC of eth1 as source MAC in icmp reply, then it will use MAC of eth0 as source MAC.

While investigating another bug, I found that the code on the incoming path in __netif_receive_skb will only set skb->skb_iif if it is already 0. When dev_forward_skb() is used in the case of interfaces like veth, skb_iif may already have been set. Making dev_forward_skb() cause the packet to look like a newly received packet would seem to the the correct behaviour here, as otherwise the wrong incoming interface can be reported for such a packet.

When using multicast over a local bridge feeding a number of LXC guests using veth, the LXC guests are unable to get a response from other guests when pinging 224.0.0.1. Multicast packets did not appear to be getting delivered to the network namespaces of the guest hosts, and further inspection showed that the incoming route was pointing to the loopback device of the host, not the guest. This lead to the wrong network namespace being picked up by sockets (like ICMP). Fix this by using the correct network namespace when creating the inbound route entry.

The flow in which the bnx2x driver starts after a previous driver has been terminated in an 'unclean' manner has several bugs and FW risks, which makes it possible for the driver to fail after boot-from-SAN or kdump.
