ipvlan: Add the skb->mark as flow4's member to lookup route

2018-02-25T10:05:47+00:00

[ Upstream commit a98a4ebc8c61d20f0150d6be66e0e65223a347af ]

Current codes don't use skb->mark to assign flowi4_mark, it would
make the policy route rule with fwmark doesn't work as expected.

ipvlan: fix ipv6 outbound device

2017-12-16T15:25:47+00:00

[ Upstream commit ca29fd7cce5a6444d57fb86517589a1a31c759e1 ]

When process the outbound packet of ipv6, we should assign the master
device to output device other than input device.

driver: ipvlan: Fix one possible memleak in ipvlan_link_new

2016-11-28T00:58:04+00:00

When ipvlan_link_new fails and creates one ipvlan port, it does not
destroy the ipvlan port created. It causes mem leak and the physical
device contains invalid ipvlan data.

ipvlan: Introduce l3s mode

2016-09-19T05:25:22+00:00

In a typical IPvlan L3 setup where master is in default-ns and
each slave is into different (slave) ns. In this setup egress
packet processing for traffic originating from slave-ns will
hit all NF_HOOKs in slave-ns as well as default-ns. However same
is not true for ingress processing. All these NF_HOOKs are
hit only in the slave-ns skipping them in the default-ns.
IPvlan in L3 mode is restrictive and if admins want to deploy
iptables rules in default-ns, this asymmetric data path makes it
impossible to do so.

This patch makes use of the l3_rcv() (added as part of l3mdev
enhancements) to perform input route lookup on RX packets without
changing the skb->dev and then uses nf_hook at NF_INET_LOCAL_IN
to change the skb->dev just before handing over skb to L4.

ipvlan: Scrub skb before crossing the namespace boundry

2016-07-26T04:47:26+00:00

The earlier patch c3aaa06d5a63 (ipvlan: scrub skb before routing
in L3 mode.) did this but only for TX path in L3 mode. This
patch extends it for both the modes for TX/RX path.

net: ipvlan: call netdev_lockdep_set_classes()

2016-06-09T20:28:37+00:00

In case a qdisc is used on a ipvlan device, we need to use different
lockdep classes to avoid false positives.

Use the new netdev_lockdep_set_classes() generic helper.

ipvlan: Fix failure path in dev registration during link creation

2016-04-28T21:23:08+00:00

When newlink creation fails at device-registration, the port->count
is decremented twice. Francesco Ruggeri (fruggeri@arista.com) found
this issue in Macvlan and the same exists in IPvlan driver too.

While fixing this issue I noticed another issue of missing unregister
in case of failure, so adding it to the fix which is similar to the
macvlan fix by Francesco in commit 308379607548 ("macvlan: fix failure
during registration v3")
