driver: ipvlan: Unlink the upper dev when ipvlan_link_new failed

2016-12-08T19:30:07Z

When netdev_upper_dev_unlink failed in ipvlan_link_new, need to unlink the ipvlan dev with upper dev. Signed-off-by: Gao Feng Acked-by: Mahesh Bandewar Signed-off-by: David S. Miller

driver: ipvlan: Fix one possible memleak in ipvlan_link_new

2016-11-28T00:58:04Z

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. Signed-off-by: Gao Feng Signed-off-by: David S. Miller

ipvlan: Introduce l3s mode

2016-09-19T05:25:22Z

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

2016-07-26T04:47:26Z

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. Signed-off-by: Mahesh Bandewar Signed-off-by: David S. Miller

net: ipvlan: call netdev_lockdep_set_classes()

2016-06-09T20:28:37Z

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. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipvlan: Fix failure path in dev registration during link creation

2016-04-28T21:23:08Z

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") Reported-by: Francesco Ruggeri Signed-off-by: Mahesh Bandewar CC: Eric Dumazet CC: Eric W.

vlan: propagate gso_max_segs

vlan drivers lack proper propagation of gso_max_segs from lower device. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipvlan: misc changes

2016-02-22T03:43:24Z

1. scope correction for few functions that are used in single file. 2. Adjust variables that are used in fast-path to fit into single cacheline 3. Update rcv_frame() to skip shared check for frames coming over wire Signed-off-by: Mahesh Bandewar Signed-off-by: David S. Miller

ipvlan: mode is u16

2016-02-22T03:43:24Z

The mode argument was erronusly defined as u32 but it has always been u16. Also use ipvlan_set_mode() helper to set the mode instead of assigning directly. This should avoid future erronus assignments / updates. Signed-off-by: Mahesh Bandewar Signed-off-by: David S. Miller
