Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller

team: remove synchronize_rcu() called during port disable

team: remove synchronize_rcu() called during queue override change

2013-06-12T10:05:53+00:00

This patch removes synchronize_rcu() from function __team_queue_override_port_del(). That can be done because it is ok to do list_del_rcu() and list_add_tail_rcu() on the same list_head member without calling synchronize_rcu() in between. A bit of refactoring needed to be done because INIT_LIST_HEAD needed to be removed (to not kill the forward pointer) as well.

team: move add to port list before port enablement

2013-06-12T07:56:27+00:00

team_port_enable() adds port to port_hashlist. Reader sees port in team_get_port_by_index_rcu() and returns it, but team_get_first_port_txable_rcu() tries to go through port_list, where the port is not inserted yet -> NULL pointer dereference. Fix this by reordering port_list and port_hashlist insertion. Panic is easily triggeable when txing packets and adding/removing port in a loop.

team: check return value of team_get_port_by_index_rcu() for NULL

2013-06-12T07:56:27+00:00

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) Signed-off-by: Jiri Pirko Signed-off-by: David S.

Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration.

team: fix port list dump for big number of ports

2013-06-01T00:31:52+00:00

In case the port list dump does not fit into one skb currently the dump would start over again. Fix this by continue from the last dumped port.
