2014-05-28mac80211: reduce packet loss notifications under loadFelix Fietkau1-6/+19
During strong signal fluctuations under high throughput, few consecutive failed A-MPDU transmissions can easily trigger packet loss notification, and thus (in AP mode) client disconnection. Reduce the number of false positives by checking the A-MPDU status flag and treating a failed A-MPDU as a single packet.

2014-05-26mac80211: add a single-transaction driver op to switch contextsLuciano Coelho2-0/+138
In some cases, when the driver is already using all the channel contexts it can handle at once, we have to do an in-place switch (ie. we cannot afford using an extra context temporarily for the transaction). But some drivers may not support switching the channel context assigned to a vif on the fly (ie. without unassigning and assigning it) while others may only work if the context is changed on the fly, without unassigning it first. To allow these different scenarios, add a new driver operation that let's the driver decide how to handle an in-place switch.

On the mgmt level we have a key type parameter which currently accepts two possible values: 0x00 for unauthenticated and 0x01 for authenticated. However, in the internal struct smp_ltk representation we have an explicit "authenticated" boolean value.

2014-05-22cfg80211: allow RSSI compensationEmmanuel Grumbach1-4/+8
Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.

The API returns a value expressed in Kbps. Also, add the new get_expected_throughput() member to the rate_control_ops structure in order to be able to query the RC algorithm (this patch provides an implementation of this API for both minstrel and minstrel_ht).

2014-05-20Bluetooth: Remove unnecessary work structs from SMP codeJohan Hedberg1-16/+6
When the SMP code was initially created (mid-2011) parts of the Bluetooth subsystem were still not converted to use workqueues. This meant that the crypto calls, which could sleep, couldn't be called directly. Because of this the "confirm" and "random" work structs were introduced. These days the entire Bluetooth subsystem runs through workqueues which makes these structs unnecessary. This patch removes them and converts the calls to queue them to use direct function calls instead.

2014-05-20Bluetooth: Make SMP context private to smp.cJohan Hedberg5-29/+32
There are no users of the smp_chan struct outside of smp.c so move it away from smp.h. The addition of the l2cap.h include to hci_core.c, hci_conn.c and mgmt.c is something that should have been there already previously to avoid warnings of undeclared struct l2cap_conn, but the compiler warning was apparently shadowed away by the mention of l2cap_conn in the struct smp_chan definition.

Users may need information about the expected throughput towards a given peer. This value is supposed to consider the size overhead generated by the 802.11 header. This value is exported in kbps through the get_station() API by including it into the station_info object. Moreover, it is sent to user space when replying to the nl80211 GET_STATION command.
