This patch cleanup 2 points for the usage of vlan_dev_priv(dev): * In vlan_dev.c/vlan_dev_hard_header, we should use the var *vlan directly after grabing the pointer at the beginning with *vlan = vlan_dev_priv(dev); when we need to access the fields of *vlan. * In vlan.c/register_vlan_device, add the var *vlan pointer struct vlan_dev_priv *vlan; to cleanup the code to access the fields of vlan_dev_priv(new_dev).

2013-07-23net: convert resend IGMP to notifier eventJiri Pirko
Until now, bond_resend_igmp_join_requests() looks for vlans attached to bonding device, bridge where bonding act as port manually. It does not care of other scenarios, like stacked bonds or team device above. Make this more generic and use netdev notifier to propagate the event to upper devices and to actually call ip_mc_rejoin_groups().

2013-07-18vlan: mask vlan prio bitsEric Dumazet
In commit 48cc32d38a52d0b68f91a171a8d00531edc6a46e ("vlan: don't deliver frames for unknown vlans to protocols") Florian made sure we set pkt_type to PACKET_OTHERHOST if the vlan id is set and we could find a vlan device for this particular id. But we also have a problem if prio bits are set. Steinar reported an issue on a router receiving IPv6 frames with a vlan tag of 4000 (id 0, prio 2), and tunneled into a sit device, because skb->vlan_tci is set. Forwarded frame is completely corrupted : We can see (8100:4000) being inserted in the middle of IPv6 source address : 16:48:00.780413 IP6 2001:16d8:8100:4000:ee1c:0:9d9:bc87 > 9f94:4d95:2001:67c:29f4::: ICMP6, unknown icmp6 type (0), length 64 0x0000: 0000 0029 8000 c7c3 7103 0001 a0ae e651 0x0010: 0000 0000 ccce 0b00 0000 0000 1011 1213 0x0020: 1415 1617 1819 1a1b 1c1d 1e1f 2021 2223 0x0030: 2425 2627 2829 2a2b 2c2d 2e2f 3031 3233 It seems we are not really ready to properly cope with this right now. We can probably do better in future kernels : vlan_get_ingress_priority() should be a netdev property instead of a per vlan_dev one. For stable kernels, lets clear vlan_tci to fix the bugs.

2013-02-11netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lockNeil Horman
__netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is already held. The mechanism is used to asynchronously call __netpoll_cleanup outside of the holding of the rtnl_lock, so as to avoid deadlock. Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the rtnl_lock must be held while calling it. Further, it cannot be held, because rcu callbacks may be issued in softirq contexts, which cannot sleep. Fix this by converting the rcu callback to a work queue that is guaranteed to get scheduled in process context, so that we can hold the rtnl properly while calling __netpoll_cleanup Tested successfully by myself.

2012-11-308021q: fix vlan device to inherit the unicast filtering capability flagYi Zou
This bug is observed on running FCoE over a VLAN device associated w/ a real device that has IFF_UNICAST_FLT set since FCoE would add unicast address such as FLOGI MAC to the VLAN interface that FCoE is on. Since currently, VLAN device is not inheriting the IFF_UNICAST_FLT flag from the parent real device even though the real device is capable of doing unicast filtering. This forces the VLAN device and its real device go to promiscuous mode unnecessarily even the added address is actually being added to the available unicast filter table in real device.

2012-10-08vlan: don't deliver frames for unknown vlans to protocolsFlorian Zumbiehl
6a32e4f9dd9219261f8856f817e6655114cfec2f made the vlan code skip marking vlan-tagged frames for not locally configured vlans as PACKET_OTHERHOST if there was an rx_handler, as the rx_handler could cause the frame to be received on a different (virtual) vlan-capable interface where that vlan might be configured. As rx_handlers do not necessarily return RX_HANDLER_ANOTHER, this could cause frames for unknown vlans to be delivered to the protocol stack as if they had been received untagged. For example, if an ipv6 router advertisement that's tagged for a locally not configured vlan is received on an interface with macvlan interfaces attached, macvlan's rx_handler returns RX_HANDLER_PASS after delivering the frame to the macvlan interfaces, which caused it to be passed to the protocol stack, leading to ipv6 addresses for the announced prefix being configured even though those are completely unusable on the underlying interface. The fix moves marking as PACKET_OTHERHOST after the rx_handler so the rx_handler, if there is one, sees the frame unchanged, but afterwards, before the frame is delivered to the protocol stack, it gets marked whether there is an rx_handler or not.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around.

2012-08-14netpoll: make __netpoll_cleanup non-blockAmerigo Wang
Like the previous patch, slave_disable_netpoll() and __netpoll_cleanup() may be called with read_lock() held too, so we should make them non-block, by moving the cleanup and kfree() to call_rcu_bh() callbacks.

slave_enable_netpoll() and __netpoll_setup() may be called with read_lock() held, so should use GFP_ATOMIC to allocate memory. Eric suggested to pass gfp flags to __netpoll_setup().

2012-07-10net: Fix memory leak - vlan_info structAmir Hanania
In driver reload test there is a memory leak. The structure vlan_info was not freed when the driver was removed. It was not released since the nr_vids var is one after last vlan was removed. The nr_vids is one, since vlan zero is added to the interface when the interface is being set, but the vlan zero is not deleted at unregister. Fix - delete vlan zero when we unregister the device.

2012-05-10Revert "net: maintain namespace isolation between vlan and real device"David S. Miller
This reverts commit 8a83a00b0735190384a348156837918271034144. It causes regressions for S390 devices, because it does an unconditional DST drop on SKBs for vlans and the QETH device needs the neighbour entry hung off the DST for certain things on transmit. Arnd can't remember exactly why he even needed this change. Conflicts: drivers/net/macvlan.c net/8021q/vlan_dev.c net/core/dev.c Signed-off-by: David S. Miller <davem@davemloft.net>
