The asyncronous firmware load uses a completion struct to hold firmware processing until the user-space routines are up and running. There is. however, a problem in that the waiter is nevered canceled during teardown. As a result, unloading the driver when firmware is not available causes an oops. To be able to access the completion structure at teardown, it had to be moved into the b43_wldev structure. This patch also fixes a typo in a comment.

In https://bugzilla.kernel.org/show_bug.cgi?id=67561, a locking dependency is reported when b43 is used with hostapd, and rfkill is used to kill the radio output. The lockdep splat (in part) is as follows: ====================================================== [ INFO: possible circular locking dependency detected ] 3.12.0 #1 Not tainted ------------------------------------------------------- rfkill/10040 is trying to acquire lock: (rtnl_mutex){+.+.+.}, at: [<ffffffff8146f282>] rtnl_lock+0x12/0x20 but task is already holding lock: (rfkill_global_mutex){+.+.+.}, at: [<ffffffffa04832ca>] rfkill_fop_write+0x6a/0x170 [rfkill] --snip-- Chain exists of: rtnl_mutex --> misc_mtx --> rfkill_global_mutex The fix is to move the initialization of the hardware random number generator outside the code range covered by the rtnl_mutex.

2014-01-13cfg80211: make regulatory_hint() remove REGULATORY_CUSTOM_REGLuis R. Rodriguez
The REGULATORY_CUSTOM_REG can be used during early init with the goal of overriding the wiphy's default regulatory settings in case the alpha2 of the device is not known. In the case that the alpha2 becomes known lets avoid having drivers having to clear the REGULATORY_CUSTOM_REG flag by doing it for them when regulatory_hint() is used.

2014-01-13ath: fix warning on usage of REGULATORY_CUSTOM_REGLuis R. Rodriguez
ath wants to first apply the custom regd and only later will it revert to not using it if an alpha2 regulatory domain is found. Since the wireless core now enforces usage of the REGULATORY_CUSTOM_REG strictly when wiphy_apply_custom_regulatory() is used this makes ath adhere to the expected behaviour but also updates the wiphy after its done with the custom usage.

2014-01-13iwlwifi: mvm: don't set the drain bit when we flush the AP stationEmmanuel Grumbach
When we disassociate in managed mode, we flush the queues after mac80211 has already removed the station. During that time, the pointer to ieee80211_sta to the fw_id_to_mac_id map is -EINVAL. In that case we should not set the station as being drained when the last Tx of this station has exited the shared Tx queue since we are flushing all the queues anyway. The draining logic is meant to be used in GO / AP mode only. In GO / AP mode, we set -EBUSY in the fw_id_to_mac_id map. This is why testing the ieee80211_sta pointer in the fw_id_to_mac_id map with IS_ERR isn't enough to set the station as draining, we need to check that it is -EBUSY. The only impact of the bug was a print: Drained sta 1, but it is internal? Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Reviewed-by: Johannes Berg <johannes.berg@intel.com>

2014-01-10net: core: explicitly select a txq before doing l2 forwardingJason Wang
Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.
