cfg80211 rejects all association requests when in associated state. This prevents clean roaming within an ESS since one would first need to disassociate before being able to request reassociation. Accept the reassociation request and let the old association to be dropped when the new one is completed. This fixes nl80211-based roaming with the current snapshot version of wpa_supplicant (that has code for requesting reassociation explicitly withthe previous BSSID attribute). Signed-off-by:

Some devices implement the entire rate control in firmware in some way, like wl1271 or like iwlwifi which does some things in software but not a lot. Therefore generic software rate control is rather useless for them and just adds avoidable overhead to the transmit path. It's fairly simple to let drivers indicate that they do not need rate control, but they need to fulfil a number of conditions that we encode in WARN_ONs. Signed-off-by:

According to IEEE80211 standard all the data packets have to be sent with TODS bit set. This patch fixes the null data packet format which was sent without TODS bit set. This should fix many problems associated with power save. Janne Ylalehto also found this fix in the same time as mine, for a different bug he was working on. Signed-off-by:

This patch increases the number of beacons to be missed before generating SYNC TIMEOUT event. It increases the beacon timeout period to 500 microseconds, which gives enough time for the firmware to receive probe response or beacon. Also handled the regain event from firmware once it receives a probe response or beacon. Signed-off-by:

Earlier firmware was stored to a memory area allocated with kmalloc() but finding a a contiguous area of memory long enough for the firmware is very difficult in certain cases. better to allocate the memory for firmware with vmalloc() instead and use a small buffer for DMA transfers. Thanks to Eero Tamminen for the idea. Signed-off-by:

Implement (slightly) delayed entry into ELP. This will cure several problems: - It works around a firmware race condition if ELP is entered too fast after commands (resulting in ELP timeout -traces) - It will reduce the number of sleep-wake cycles between already scheduled events such as interrupts and tx, hence improving performance (less delay in switching between RX and TX) Signed-off-by: -

At least two revisions of the D-Link DWA 160 exist, called A1 and A2. A1 (USB-ID 07d1:3c10) is already listed in usb.c as D-Link DWA 160A. A2 (USB-ID 07d1:3a09) works if added to ar9170_usb_ids. I didn't do much testing until now, but I was able to connect to APs using WPA or WEP and transmit data. Summary: * Add model revision number to the comment for D-Link DWA 160 A1 (07d1:3c10) * Add support for D-Link DWA 160 A2 (07d1:3a09) Signed-off-by:

The netdev broadcast address cannot change from all-ones so there's no need to use it; we can instead hard-code it. Since we already have an instance in tkip.c, which will be shared if it is marked static const, doing this reduces text size at no data/bss cost. The real motivation for this is, of course, the desire to get rid of almost all uses of netdevs in mac80211 so that auditing their use becomes easier. Signed-off-by:

Some code currently assumes that there's a valid rate pointer even in the HT case, but there can't be. To reduce reliance on that, remove the rate pointer from the RX data struct and pass it where it's needed. Also, for now, in radiotap announce HT frames as having a DYN channel type, and remove their rate from cooked monitor radiotap completely (it isn't present in the regular monitor radiotap either.)

The RX data contains the netdev, which is duplicated since we have the sdata, and the RX status pointer, which is duplicate since we have the skb. Remove those two fields to have fewer fields that depend on each other and simply load them as necessary. Signed-off-by:

The reorder buffer handling is written in a quite peculiar style (especially comments) and also has a quirk where it invokes the entire reorder code in ieee80211_sta_manage_reorder_buf() for just a handful of lines in it with a special argument. Split out ieee80211_release_reorder_frames which can then be invoked from BAR handling and other reordering code, clean up code and comments and remove function arguments that are now unused from ieee80211_sta_manage_reorder_buf().

When we receive a michael MIC failure report from the hardware we currently do not check whether it is actually reported on a frame that is destined to us. It shouldn't be possible to get a michael MIC failure report on other frames, but it also doesn't hurt to verify. Also, since we then don't need the station struct that early, move looking it up a bit later in the RX path. Finally, while at it, a few code cleanups in the area. Signed-off-by:

The entire aggregation code currently operates on the hw pointer and station addresses, but that needs to change to make stations purely per-vif; As one step preparing for that make the aggregation code callable with the station, or by the combination of virtual interface and station address.

* Remove a code chunk dealing with operating mode changes. As noted, all such policy changes are to be done in add_interface. * Remove pointless check for empty BSSID. Also, remove mode checks - mac80211 does all the needed checks. * Handle enabling/disabling beacon transmission properly. * Handle beacon interval changes for AP mode. The original code depended on config_interface() to update the HW TSF. Since that callback has been removed, handle it properly. * Remove unneeded code dealing with key/privacy. * Set the chainmasks to 1x1 for IBSS when the BSSID is set. This was happening uncondionally before. Signed-off-by:

In order to handle association and authentication in AP mode, hostapd needs access to the tx status info of its own frames through a cooked monitor interface. Without this patch the cooked monitor interfaces also passed on tx status information for packets from other virtual interfaces. This creates a significant performance issue on embedded system. Hostapd tries to work around this by installing a Linux Socket Filter that only captures the frames it's interested in, however data duplication and socket filter matching still uses up enough CPU cycles to be very noticeable on small systems. This patch ensures that tx status information of non-injected frames does not make it to cooked monitor interfaces. Signed-off-by:

Using the new mac80211 functionality, this makes iwlwifi handle unicast PS buffering correctly. The device works like this: * when a station goes to sleep, the microcode notices this and marks the station as asleep * when the station is marked asleep, the microcode refuses to transmit to the station and rejects all frames queued to it with the failure status code TX_STATUS_FAIL_DEST_PS (a previous patch handled this correctly) * when we need to send frames to the station _although_ it is asleep, we need to tell the ucode how many, and this is asynchronous with sending so we cannot just send the frames, we need to wait for all other frames to be flushed, and then update the counter before sending out the poll response frames. This is handled partially in the driver and partially in mac80211. In order to do all this correctly, we need to * keep track of how many frames are pending for each associated client station (avoid doing it for other stations to avoid the atomic ops) * tell mac80211 that we driver-block the PS status while there are still frames pending on the queues, and once they are all rejected (due to the dest sta being in PS) unblock mac80211 Signed-off-by:
