cfg80211: allow mgmt_frame_register callback to sleep

2015-07-17T13:38:26+00:00

This callback is currently not allowed to sleep, which makes it more
difficult to implement proper driver methods in mac80211 than it has
to be. Instead of doing asynchronous work here in mac80211, make it
possible for the callback to sleep by doing some asynchronous work
in cfg80211. This also enables improvements to other drivers, like
ath6kl, that would like to sleep in this callback.

While at it, also fix the code to call the driver on the implicit
unregistration when an interface is removed, and do that also when
a P2P-Device wdev is destroyed (otherwise we leak the structs.)

cfg80211: pass name_assign_type to rdev_add_virtual_intf()

2015-03-30T08:36:17+00:00

This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

Similar functionality was introduced for the rtnetlink core in
commit 5517750f058e ("net: rtnetlink - make create_link take name_assign_type")

cfg80211: introduce TDLS channel switch commands

2014-11-19T17:45:12+00:00

Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.

Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

cfg80211: 802.11p OCB mode handling

2014-11-04T12:18:17+00:00

This patch adds new iface type (NL80211_IFTYPE_OCB) representing
the OCB (Outside the Context of a BSS) mode.
When establishing a connection to the network a cfg80211_join_ocb
function is called (particular nl80211_command is added as well).
A mandatory parameters during the ocb_join operation are 'center
frequency' and 'channel width (5/10 MHz)'.

Changes done in mac80211 are minimal possible required to avoid
many warnings (warning: enumeration value 'NL80211_IFTYPE_OCB'
not handled in switch) during compilation. Full functionality
(where needed) is added in the following patch.

cfg80211: Convert del_station() callback to use a param struct

2014-10-20T14:24:21+00:00

This makes it easier to add new parameters for the del_station calls
without having to modify all drivers that use this.

cfg80211: add ops to query mesh proxy path table

cfg80211: add WMM traffic stream API

2014-09-11T10:21:18+00:00

Add nl80211 and driver API to validate, add and delete traffic
streams with appropriate settings.

The API calls for userspace doing the action frame handshake
with the peer, and then allows only to set up the parameters
in the driver. To avoid setting up a session only to tear it
down again, the validate API is provided, but the real usage
later can still fail so userspace must be prepared for that.

cfg80211: pass TDLS initiator in tdls_mgmt operations

2014-06-23T12:24:55+00:00

The TDLS initiator is set once during link setup. If determines the
address ordering in the link identifier IE.

Fix dependent drivers - mwifiex and mac80211.

cfg80211: make ethtool the driver's responsibility

2014-06-23T09:05:33+00:00

Currently, cfg80211 tries to implement ethtool, but that doesn't
really scale well, with all the different operations. Make the
lower-level driver responsible for it, which currently only has
an effect on mac80211. It will similarly not scale well at that
level though, since mac80211 also has many drivers.

To cleanly implement this in mac80211, introduce a new file and
move some code to appropriate places.

cfg80211: implement cfg80211_get_station cfg80211 API

2014-05-21T07:15:17+00:00

Implement and export the new cfg80211_get_station() API.
This utility can be used by other kernel modules to obtain
detailed information about a given wireless station.

It will be in particular useful to batman-adv which will
implement a wireless rate based metric.
