There is not core id with 0x4329, but at the same place in the open source part of the Broadcom SDK is a check for some device with the chip id of 0x4329. The device with a chip id of 0x4329 is a full mac device, so it will never be supported by bcma, this part is running in the firmware of the device and not on the host CPU. This code is wrong and will never be used, so just remove it. Signed-off-by:

Pass cfg80211_beacon_data pointer instead of cfg80211_ap_settings. While setting management IEs we only need cfg80211_beacon_data of cfg80211_ap_settings which has Tail IE, Head IE and other IE elements. Signed-off-by:

When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys. Reported-by:

This is iwlegacy version of: commit 342bbf3f Author: Johannes Berg <johannes.berg@intel.com> Date: Sun Mar 4 08:50:46 2012 -0800 iwlwifi: always monitor for stuck queues If we only monitor while associated, the following can happen: - we're associated, and the queue stuck check runs, setting the queue "touch" time to X - we disassociate, stopping the monitoring, which leaves the time set to X - almost 2s later, we associate, and enqueue a frame - before the frame is transmitted, we monitor for stuck queues, and find the time set to X, although it is now later than X + 2000ms, so we decide that the queue is stuck and erroneously restart the device Cc: stable@vger.kernel.org Signed-off-by:

On rt2x00_dmastart() we increase index specified by Q_INDEX and on rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries between Q_INDEX_DONE and Q_INDEX are those we currently process in the hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can submit to the hardware. According to that fix rt2x00usb_kick_queue(), as we need to submit RX entries that are not processed by the hardware. It worked before only for empty queue, otherwise was broken. Note that for TX queues indexes ordering are ok. We need to kick entries that have filled skb, but was not submitted to the hardware, i.e. started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set. From practical standpoint this fixes RX queue stall, usually reproducible in AP mode, like for example reported here: https://bugzilla.redhat.com/show_bug.cgi?id=828824Reported-and-tested-by:

If association failed due to internal error (e.g. no supported rates IE), we call ieee80211_destroy_assoc_data() with assoc=true, while we actually reject the association. This results in the BSSID not being zeroed out. After passing assoc=false, we no longer have to call sta_info_destroy_addr() explicitly. While on it, move the "associated" message after the assoc_success check. Cc: stable@vger.kernel.org [3.4+] Signed-off-by:

Larry (and some others I think) reported that with single-queue drivers mac80211 crashes when waking the queues. This happens because we allocate just a single queue for each virtual interface in case the driver doesn't have at least 4 queues, but the code stopping/waking the virtual interface queues wasn't taking this into account.

If the interfaces were removed just before a restart work was started, open_count will be 0, and most of the reconfig work will be skipped, including the resetting of local->in_reconfig to false. Leaving local->inconfig = true will result in dropping any incoming packet. Fix it by always setting local->in_reconfig = false (even if there are no active interfaces). Signed-off-by:

Due to the way the default key links are created, it happens that a link is left dangling: * both unicast/multicast links are created * unicast link is destroyed, and the links are updated * during this update, adding the multicast link again fails because it is present, destroying the debugfs pointer * removing the multicast link won't work as the pointer has been destroyed Fix this by always removing the links and then re-creating them if needed.

Until now, a u16 value was used to represent bitrate value. With VHT bitrates this becomes too small. Introduce a new 32-bit bitrate attribute. nl80211 will report both the new and the old attribute, unless the bitrate doesn't fit into the old u16 attribute in which case only the new one will be reported. User space tools encouraged to prefer the 32-bit attribute, if available (since it won't be available on older kernels.) Signed-off-by:

Michal's monitor channel tracking introduce a locking problem as it locked the rdev lock inside the netdev notifier which isn't allowed as we might already hold it if we get there by removing an interface that is up. Fix this by relying only on the RTNL to protect the interface counters, the RTNL is always held in these code paths anyway. Signed-off-by:

Some drivers require setup before being able to send management frames in managed mode, in particular in multi-channel cases. Introduce API to allow the drivers to do such setup while being able to sleep waiting for the setup to finish in the device. This isn't possible inside the TX call since that can't sleep. A future patch may also restructure the TX retry to wait for the driver to report the frame status, as suggested by Arik in http://mid.gmane.org/CA+XVXffKSEL6ZQPQ98x-zO-NL2=TNF1uN==mprRyUmAaRn254g@mail.gmail.comSigned-off-by:

IEEE80211_TX_MAX_RATES can be reduced from 5 to 4 as there is no current hardware supporting a rate chain with 5 multi rate stages (mrr), so 4 mrr stages are sufficient. The memory that is freed within the ieee80211_tx_info struct will be used in the upcoming Transmission Power Control (TPC) implementation. Suggested-by:
