Channel Switch will later require to generate beacons without setting them immediately. Therefore split the presp generation in an own function. Splitting the original very long function might be a good idea anyway. Signed-off-by:

This patch decouples the power save processing from the frame decryption by running the decrypt rx handler after sta_process. In the case where the decryption failed for some reason, the stack used to not process the PM and MOREDATA bits for that frame. The stack now always performs power save processing regardless of the decryption result. That means that encrypted data frames and NULLFUNC frames are now handled in the same way regarding power save processing, making the stack more robust. Signed-off-by:

Function regulator_enable() may return an error that has to be checked. This patch changes function rfkill_regulator_set_block() so that it checks for the return code. Also, rfkill_data->reg_enabled is set to 'true' only if there is no error. This fixes the following compilation warning: net/rfkill/rfkill-regulator.c:43:20: warning: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Wunused-result] Signed-off-by:

In some cases mac80211 will scan before creating an IBSS even if bssid and frequency have been forced by the user. This is not needed and leads only to a delay in the IBSS establishment phase. Immediately create the cell if both bssid and frequency (and fixed_freq is set) have been specified. Signed-off-by:

A lot of drivers check the frame protocol for ETH_P_PAE, for various reasons (like making those more reliable). Add a new flags bitmap to the TX control info and a new flag indicating the control port protocol is in use to let all drivers also apply such logic to other control port protocols, should they be configured. Also use the new flag in the iwlwifi drivers. Signed-off-by: -

Clean up the CQM settings code a bit and while at it enforce that when setting the threshold to 0 (disable) the hysteresis is also set to 0 to avoid confusion. As we haven't enforce it, simply override userspace. Signed-off-by:

Allow lowest basic rate to be used for unicast management frame in mesh. Otherwise, the lowest supported rate is used for unicast management frame, such as 1Mbps for 2.4GHz and 6Mbps for 5GHz. Rename the rc_send_low_broadcast to re_send_low_basicrate since now it is also applied to unicast management frame in mesh. Signed-off-by:

The count field in CSA must be decremented with each beacon transmitted. This patch implements the functionality for drivers using ieee80211_beacon_get(). Other drivers must call back manually after reaching count == 0. This patch also contains the handling and finish worker for the channel switch command, and mac80211/chanctx code to allow to change a channel definition of an active channel context. Signed-off-by:

The radiotap VHT info is 12 bytes (required to be aligned on 2) : u16 known - IEEE80211_RADIOTAP_VHT_KNOWN_* u8 flags - IEEE80211_RADIOTAP_VHT_FLAG_* u8 bandwidth u8 mcs_nss[4] u8 coding u8 group_id u16 partial_aid ATM mac80211 can handle IEEE80211_RADIOTAP_VHT_KNOWN_{GI,BANDWIDTH} and mcs_nss[0] (i.e single user) in simple cases. This is more a placeholder to let sniffers give more clues for VHT, since we don't have yet the proper infrastructure/conventions in mac80211 for complete feedback (e.g consider dynamic BW).

A station which is not authorized has to be purged earlier to give it a chance to re-try to establish an IBSS/RSN session soon. Set the timeout to 10 seconds. Some refactoring has also been done to allow the IBSS submodule to have its own expiring function. Reported-by:

Change mac80211 LED trigger code to use the generic led_trigger_blink_oneshot() API for transmit and receive activity indication. This gives a better feedback to the user, as with the new API each activity event results in a visible blink, while a constant traffic results in a continuous blink at constant rate. Signed-off-by:

There is an off-by-one error in the beacon generation for the ibss mode, falsely a rate the extended supported rates which was already added to supported rates, messing up the beacon. This was introduced by commit "mac80211: select and adjust bitrates according to channel mode". Signed-off-by:

There appear to be two regressions in ibss.c when calling ieee80211_sta_def_wmm_params(): * the second argument should be a rate length, not a rate array. This was introduced by my commit "mac80211: select and adjust bitrates according to channel mode" * the third argument is not initialized (anymore), making further checks within this function useless. Since ieee80211_sta_def_wmm_params() is only used by ibss anyway, remove the function entirely and handle the operating mode decision immediately. Signed-off-by:

Some regulations (like germany, but also FCC) express their transmission power limit in dBm/MHz or mW/MHz. To cope with that and be on the safe side, reduce the maximum power to half (10 MHz) or quarter (5 MHz) when operating on these reduced bandwidth channels. Signed-off-by:

The various components accessing the bitrates table must use consider the used channel bandwidth to select only available rates or calculate the bitrate correctly. There are some rates in reduced bandwidth modes which can't be represented as multiples of 500kbps, like 2.25 MBit/s in 5 MHz mode. The standard suggests to round up to the next multiple of 500kbps, just do that in mac80211 as well. Signed-off-by:

In most cases, host that receives IPv4 and IPv6 multicast/broadcast packets does not do anything with these packets. Therefore the reception of these unwanted packets causes unnecessary processing and power consumption. Packet coalesce feature helps to reduce number of received interrupts to host by buffering these packets in firmware/hardware for some predefined time. Received interrupt will be generated when one of the following events occur. a) Expiration of hardware timer whose expiration time is set to maximum coalescing delay of matching coalesce rule. b) Coalescing buffer in hardware reaches it's limit. c) Packet doesn't match any of the configured coalesce rules. This patch adds set/get configuration support for packet coalesce. User needs to configure following parameters for creating a coalesce rule. a) Maximum coalescing delay b) List of packet patterns which needs to be matched c) Condition for coalescence. pattern 'match' or 'no match' Multiple such rules can be created. This feature needs to be advertised during driver initialization. Drivers are supposed to do required firmware/hardware settings based on user configuration. Signed-off-by:
