2008-01-23iwlwifi: fix possible read attempt on ucode that is not availableReinette Chatre
This fixes a NULL pointer dereference that can occur when the ucode is not loaded at the time __iwl_up is called.

2007-12-20iwlwifi: fix possible priv->mutex deadlock during suspendZhu Yi
This patch moves _cancel_deferred_work out of mutex protection and removes unnecessary mutex in pci_suspend and pci_resume. Cc: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-12-17iwlwifi: fix rf_kill state inconsistent during suspend and resumeZhu Yi
The patch fixes the STATUS_RF_KILL_HW state is not cleared problem if the device goes to suspend when the rf_kill switch is enabled. The bug causes the driver always thinks the rf_kill switch is enabled (although it is disabled) after resume. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

2007-12-17iwlwifi3945/4965: fix rate control algo reference leakCyrill Gorcunov
Fix rate control algo reference leak in case if network device has been failed to register. In this case special flag priv->mac80211_registered is not set and the rate algo reference is not freeing on module unload. That leads to OOPs in further ieee80211 rate register/unregister procedure (by any callee).

The interrupt handler returns IRQ_NONE if it detects that the device is gone. That's incorrect because the device may have raised the interrupt.

2007-11-11iwlwifi: select proper rate control algorithmJohannes Berg
Prior to this patch, iwlwifi would always use the first registered rate control algorithm which, depending on system setup, could be anything. After the mac80211 patch to make the simple algorithm built-in, it would always be simple. This has always been a bug in iwlwifi. This fixes it by requesting that mac80211 selects the right rate control algorithm. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2007-10-10[PATCH] mac80211: revamp interface and filter configurationJohannes Berg
Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
