Flip the IPv6 output path to use the l3mdev tx out hook. The VRF dst is not returned on the first FIB lookup. Instead, the dst on the skb is switched at the beginning of the IPv6 output processing to send the packet to the VRF driver on xmit. Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in. Convert the existing vrf_get_rt6_dst to handle only link scope addresses. Signed-off-by:

IPv6 source address selection needs to consider the real egress route. Similar to IPv4 implement a get_saddr6 method which is called if source address has not been set. The get_saddr6 method does a full lookup which means pulling a route from the VRF FIB table and properly considering linklocal/multicast destination addresses. Lookup failures (eg., unreachable) then cause the source address selection to fail which gets propagated back to the caller. Signed-off-by:

Attempting to delete a VRF device with a socket bound to it can stall: unregister_netdevice: waiting for red to become free. Usage count = 1 The unregister is waiting for the dst to be released and with it references to the vrf device. Similar to dst_ifdown switch the dst dev to loopback on delete for all of the dst's for the vrf device and release the references to the vrf device.

1. Default VRF devices to not having a qdisc (IFF_NO_QUEUE). Users can add one as desired. 2. Disable adding a VLAN to a VRF device. 3. Enable offloads and hardware features similar to other logical devices (e.g., dummy, veth) Change provides a significant boost in TCP stream Tx performance, from ~2,700 Mbps to ~18,100 Mbps and makes throughput close to the performance without a VRF (18,500 Mbps). netperf TCP_STREAM benchmark using qemu with virtio+vhost for the NICs Signed-off-by:

IPv6 multicast and link-local addresses require special handling by the VRF driver: 1. Rather than using the VRF device index and full FIB lookups, packets to/from these addresses should use direct FIB lookups based on the VRF device table. 2. fail sends/receives on a VRF device to/from a multicast address (e.g, make ping6 ff02::1%<vrf> fail) 3. move the setting of the flow oif to the first dst lookup and revert the change in icmpv6_echo_reply made in ca254490 ("net: Add VRF support to IPv6 stack"). Linklocal/mcast addresses require use of the skb->dev. With this change connections into and out of a VRF enslaved device work for multicast and link-local addresses work (icmp, tcp, and udp) e.g., 1. packets into VM with VRF config: ping6 -c3 fe80::e0:f9ff:fe1c:b974%br1 ping6 -c3 ff02::1%br1 ssh -6 fe80::e0:f9ff:fe1c:b974%br1 2. packets going out a VRF enslaved device: ping6 -c3 fe80::18f8:83ff:fe4b:7a2e%eth1 ping6 -c3 ff02::1%eth1 ssh -6 root@fe80::18f8:83ff:fe4b:7a2e%eth1 Signed-off-by:

The problem above is due to the fact that the fib hash table is not allocated when IPv6 is disabled at boot. As for the VRF driver it should not do any IPv6 initializations if IPv6 is disabled, so it needs to know if IPv6 is disabled at boot. The disable parameter is private to the IPv6 module, so provide an accessor for modules to determine if IPv6 was disabled at boot time.

The VRF device exists to define L3 domains and guide FIB lookups. As such its operstate is not relevant. Seeing 'state UNKNOWN' in the output of 'ip link show' can be confusing, so set operstate at link create. Similarly, the MTU for a VRF device is not used; any fragmentation of the payload is done on the output path based on the real egress device. An MTU of 1500 on the VRF device while enslaved devices have a higher MTU can lead to confusion. Since the VRF MTU is not relevant set to 64k similar to what is done for loopback. Signed-off-by:

One cpu can be processing packets which includes using the cached route entries in the vrf device's private data and on another cpu the device gets deleted which releases the routes and sets the pointers in net_vrf to NULL. This results in datapath dereferencing a NULL pointer. Fix by protecting access to dst's with rcu.

Currently the VRF driver uses the rx_handler to switch the skb device to the VRF device. Switching the dev prior to the ip / ipv6 layer means the VRF driver has to duplicate IP/IPv6 processing which adds overhead and makes features such as retaining the ingress device index more complicated than necessary. This patch moves the hook to the L3 layer just after the first NF_HOOK for PRE_ROUTING. This location makes exposing the original ingress device trivial (next patch) and allows adding other NF_HOOKs to the VRF driver in the future. dev_queue_xmit_nit is exported so that the VRF driver can cycle the skb with the switched device through the packet taps to maintain current behavior (tcpdump can be used on either the vrf device or the enslaved devices).

Allow udp and raw sockets to send by oif that is an enslaved interface versus the l3mdev/VRF device. For example, this allows BFD to use ifindex from IP_PKTINFO on a receive to send a response without the need to convert to the VRF index. It also allows ping and ping6 to work when specifying an enslaved interface (e.g., ping -I swp1 <ip>) which is a natural use case. Signed-off-by:

Vivek reported a kernel exception deleting a VRF with an active connection through it. The root cause is that the socket has a cached reference to a dst that is destroyed. Converting the dst_destroy to dst_release and letting proper reference counting kick in does not work as the dst has a reference to the device which needs to be released as well. I talked to Hannes about this at netdev and he pointed out the ipv4 and ipv6 dst handling has dst_ifdown for just this scenario. Rather than continuing with the reinvented dst wheel in VRF just remove it and leverage the ipv4 and ipv6 versions.

The private slave queue and slave struct haven't been used for anything and aren't needed, this allows to reduce memory usage and simplify enslave/release. We can use netdev_for_each_lower_dev() to free the vrf ports when deleting a vrf device. Also if in the future a private struct is needed for each slave, it can be implemented via lower devices' private member (similar to how bonding does it). Signed-off-by:

When vrf's ->newlink is called, if register_netdevice() fails then it does free_netdev(), but that's also done by rtnl_newlink() so a second free happens and memory gets corrupted, to reproduce execute the following line a couple of times (1 - 5 usually is enough): $ for i in `seq 1 5`; do ip link add vrf: type vrf table 1; done; This works because we fail in register_netdevice() because of the wrong name "vrf:". And here's a trace of one crash: [ 28.792157] ------------[ cut here ]------------ [ 28.792407] kernel BUG at fs/namei.c:246!
