team: check return value of team_get_port_by_index_rcu() for NULL

2013-06-27T18:27:32+00:00

[ Upstream commit 76c455decbbad31de21c727edb184a963f42b40b ]

team_get_port_by_index_rcu() might return NULL due to race between port
removal and skb tx path. Panic is easily triggeable when txing packets
and adding/removing port in a loop.

introduced by commit 3d249d4ca "net: introduce ethernet teaming device"
and commit 753f993911b "team: introduce random mode" (for random mode)

net: use eth_hw_addr_random() and reset addr_assign_type

2012-02-15T20:34:17+00:00

Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: adapt to renamed eth_hw_addr_random()

team: send only changed options/ports via netlink

2012-01-24T20:51:00+00:00

This patch changes event message behaviour to send only updated records
instead of whole list. This fixes bug on which userspace receives non-actual
data in case multiple events occur in row.

team: use vlan_vids_[addr/del]_by_dev

2011-12-09T00:52:43+00:00

So far when vlan id was added to team device befor port was added, this
vid was not added to port's vlan filter. Also after removal, vid stayed
in port device's vlan filter. Benefit of new vlan functions to handle
this work.

net: introduce vlan_vid_[add/del] and use them instead of direct [add/kill]_vid ndo calls

2011-12-09T00:52:42+00:00

This patch adds wrapper for ndo_vlan_rx_add_vid/ndo_vlan_rx_kill_vid
functions. Check for NETIF_F_HW_VLAN_FILTER feature is done in this
wrapper.

net: make vlan ndo_vlan_rx_[add/kill]_vid return error value

2011-12-09T00:52:37+00:00

Let caller know the result of adding/removing vlan id to/from vlan
filter.

In some drivers I make those functions to just return 0. But in those
where there is able to see if hw setup went correctly, return value is
set appropriately.

net: treewide use of RCU_INIT_POINTER

2011-11-23T23:48:19+00:00

rcu_assign_pointer(ptr, NULL) can be safely replaced by
RCU_INIT_POINTER(ptr, NULL)

(old rcu_assign_pointer() macro was testing the NULL value and could
omit the smp_wmb(), but this had to be removed because of compiler
warnings)

team: avoid using variable-length array

2011-11-18T19:55:00+00:00

Apparently using variable-length array is not correct
(https://lkml.org/lkml/2011/10/23/25). So remove it.
