cfg80211: fix mic_failure tracing

2014-07-18T07:53:56+00:00

tsc can be NULL (mac80211 currently always passes NULL),
resulting in NULL-dereference. check before copying it.

cfg80211: Support multiple CSA counters

2014-05-15T13:00:42+00:00

Change the type of NL80211_ATTR_CSA_C_OFF_BEACON and
NL80211_ATTR_CSA_C_OFF_PRESP to be NLA_BINARY which allows
userspace to use beacons and probe responses with
multiple CSA counters.
This isn't breaking the API since userspace can
continue to use nla_put_u16 for this attributes, which
is equivalent to a single element u16 array.
In addition advertise max number of supported CSA counters.
This is needed when using CSA and eCSA IEs together.

cfg80211: export interface stopping function

2014-05-06T13:16:34+00:00

This exports a new cfg80211_stop_iface() function.

This is intended for driver internal interface
combination management and channel switching.

Due to locking issues (it re-enters driver) the
call is asynchronous and uses cfg80211 event
list/worker.

cfg80211: Dynamic channel bandwidth changes in AP mode

2014-04-28T16:09:59+00:00

This extends NL80211_CMD_SET_CHANNEL to allow dynamic channel bandwidth
changes in AP mode (including P2P GO) during a lifetime of the BSS. This
can be used to implement, e.g., HT 20/40 MHz co-existence rules on the
2.4 GHz band.

cfg80211: Enable GO operation on additional channels

2014-04-09T08:55:34+00:00

Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT
iff there is an active station interface that is associated to
an AP operating on the same channel in the 2 GHz band or the same UNII band
(in the 5 GHz band). This relaxation is not allowed if the channel is
marked with IEEE80211_CHAN_RADAR.

Note that this is a permissive approach to the FCC definitions,
that require a clear assessment that the device operating the AP is
an authorized master, i.e., with radar detection and DFS capabilities.

It is assumed that such restrictions are enforced by user space.
Furthermore, it is assumed, that if the conditions that allowed for
the operation of the GO on such a channel change, i.e., the station
interface disconnected from the AP, it is the responsibility of user
space to evacuate the GO from the channel.

cfg80211: Pass TDLS peer capability information in tdls_mgmt

2014-02-20T10:55:25+00:00

While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct
the VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the
presence of the respective IEs in the received TDLS Setup Response frame.

The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

cfg80211: fix channel configuration in IBSS join

2014-02-04T20:58:16+00:00

When receiving an IBSS_JOINED event select the BSS object
based on the {bssid, channel} couple rather than the bssid
only.
With the current approach if another cell having the same
BSSID (but using a different channel) exists then cfg80211
picks up the wrong BSS object.
The result is a mismatching channel configuration between
cfg80211 and the driver, that can lead to any sort of
problem.

The issue can be triggered by having an IBSS sitting on
given channel and then asking the driver to create a new
cell using the same BSSID but with a different frequency.
By passing the channel to cfg80211_get_bss() we can solve
this ambiguity and retrieve/create the correct BSS object.
All the users of cfg80211_ibss_joined() have been changed
accordingly.

Moreover WARN when cfg80211_ibss_joined() gets a NULL
channel as argument and remove a bogus call of the same
function in ath6kl (it does not make sense to call
cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

cfg80211: Add support for QoS mapping

2013-12-19T15:29:22+00:00

This allows QoS mapping from external networks to be implemented as
defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise
DSCP ranges and exceptions for mapping frames to a specific UP over
Wi-Fi.

The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97)
is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to
configure the local behavior either on the AP (based on local
configuration) or on a station (based on information received from the
AP).

cfg80211: aggregate mgmt_tx parameters into a struct

2013-12-02T10:51:52+00:00

Change cfg80211 and mac80211 to use cfg80211_mgmt_tx_params
struct to aggregate parameters for mgmt_tx functions.
This makes the functions' signatures less clumsy and allows
less painful parameters extension.
