ipvlan: fix check for IP addresses in control path

2015-03-31T17:28:33Z

When an ipvlan interface is down, its addresses are not on the hash list. Fix checks for existence of addresses not to depend on the hash list, walk through all interface addresses instead. Signed-off-by: Jiri Benc Acked-by: Mahesh Bandewar Signed-off-by: David S. Miller

ipvlan: do not use rcu operations for address list

2015-03-31T17:28:33Z

All accesses to ipvlan->addrs are under rtnl. Signed-off-by: Jiri Benc Signed-off-by: David S. Miller

ipvlan: protect against concurrent link removal

2015-03-31T17:28:33Z

Adding and removing to the 'ipvlans' list is already done using _rcu list operations. Signed-off-by: Jiri Benc Signed-off-by: David S. Miller

ipvlan: fix addr hash list corruption

2015-03-31T17:28:33Z

When ipvlan interface with IP addresses attached is brought down and then deleted, the assigned addresses are deleted twice from the address hash list, first on the interface down and second on the link deletion. Similarly, when an address is added while the interface is down, it is added second time once the interface is brought up. When the interface is down, the addresses should be kept off the hash list for performance reasons. Ensure this is true, which also fixes the double add problem. To fix the double free, check whether the address is hashed before removing it. Reported-by: Dan Williams Signed-off-by: Jiri Benc Signed-off-by: Mahesh Bandewar Signed-off-by: David S. Miller

ipvlan: add a missing __percpu pcpu_stats

2015-02-12T04:03:23Z

Cosmetic patch to add __percpu qualifier to pcpu_stats Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: mark some potential candidates __read_mostly

2015-01-31T01:58:39Z

They are all either written once or extremly rarely (e.g. from init code), so we can move them to the .data..read_mostly section. Signed-off-by: Daniel Borkmann Signed-off-by: David S. Miller

ipvlan: fix incorrect usage of IS_ERR() macro in IPv6 code path.

2015-01-25T08:24:19Z

The ip6_route_output() always returns a valid dst pointer unlike in IPv4 case. So the validation has to be different from the IPv4 path. Correcting that error in this patch. This was picked up by a static checker with a following warning - drivers/net/ipvlan/ipvlan_core.c:380 ipvlan_process_v6_outbound() warn: 'dst' isn't an ERR_PTR Signed-off-by: Mahesh Bandewar Reported-by: Dan Carpenter Signed-off-by: David S.

ipvlan: move the device check function into netdevice.h

2014-12-09T21:10:06Z

Move the port check [ipvlan_dev_master()] and device check [ipvlan_dev_slave()] functions to netdevice.h and rename them netif_is_ipvlan_port() and netif_is_ipvlan() resp. to be consistent with macvlan api naming. Signed-off-by: Mahesh Bandewar Signed-off-by: David S. Miller

ipvlan: play well with macvlan device

2014-12-09T21:10:06Z

If a device is already a macvlan port then refuse to use it as an ipvlan port in the early stage of port creation. thost1:~# ip link add link eth0 mvl0 type macvlan thost1:~# echo $? 0 thost1:~# ip link add link eth0 ipvl0 type ipvlan RTNETLINK answers: Device or resource busy thost1:~# echo $? 2 thost1:~# Signed-off-by: Mahesh Bandewar Signed-off-by: David S.

net-ipvlan: Deletion of an unnecessary check before the function call "free_percpu"

2014-12-06T05:14:20Z

The free_percpu() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Acked-by: Mahesh Bandewar Signed-off-by: David S. Miller
