cfg80211: clean up includes

2009-04-22T20:57:17+00:00

Trying to separate header files into net/wireless.h and
net/cfg80211.h has been a source of confusion. Remove
net/wireless.h (because there also is the linux/wireless.h)
and subsume everything into net/cfg80211.h -- except the
definitions for regulatory structures which get moved to
a new header net/regulatory.h.

The "new" net/cfg80211.h is now divided into sections.

There are no real changes in this patch but code shuffling
and some very minor documentation fixes.

I have also, to make things reflect reality, put in a
copyright line for Luis to net/regulatory.h since that
is probably exclusively written by him but was formerly
in a file that only had my copyright line.

cfg80211/nl80211: add IBSS API

2009-04-22T20:57:17+00:00

This adds IBSS API along with (preliminary) wext handlers.
The wext handlers can only do IBSS so you need to call them
from your own wext handlers if the mode is IBSS.

The nl80211 API requires
 * an SSID
 * a channel (frequency) for the case that a new IBSS
   has to be created

It optionally supports
 * a flag to fix the channel
 * a fixed BSSID

The cfg80211 code also takes care to leave the IBSS before
the netdev is set down. If wireless extensions are used, it
also caches values when the interface is down and instructs
the driver to join when the interface is set up.

cfg80211: add cipher capabilities

2009-04-22T20:54:40+00:00

This adds the necessary code and fields to let drivers specify
their cipher capabilities and exports them to userspace. Also
update mac80211 to export the ciphers it has.

cfg80211: introduce scan IE limit attribute

2009-04-22T20:54:39+00:00

This patch introduces a new attribute for a wiphy that tells
userspace how long the information elements added to a probe
request frame can be at most. It also updates the at76 to
advertise that it cannot support that, and, for now until I
can fix that, iwlwifi too.

cfg80211: Add AP beacon regulatory hints

2009-02-27T19:52:59+00:00

When devices are world roaming they cannot beacon or do active scan
on 5 GHz or on channels 12, 13 and 14 on the 2 GHz band. Although
we have a good regulatory API some cards may _always_ world roam, this
is also true when a system does not have CRDA present. Devices doing world
roaming can still passive scan, if they find a beacon from an AP on
one of the world roaming frequencies we make the assumption we can do
the same and we also remove the passive scan requirement.

This adds support for providing beacon regulatory hints based on scans.
This works for devices that do either hardware or software scanning.
If a channel has not yet been marked as having had a beacon present
on it we queue the beacon hint processing into the workqueue.

All wireless devices will benefit from beacon regulatory hints from
any wireless device on a system including new devices connected to
the system at a later time.

cfg80211: move all regulatory hints to workqueue

2009-02-27T19:52:57+00:00

All regulatory hints (core, driver, userspace and 11d) are now processed in
a workqueue.

cfg80211: clean up signal type

2009-02-27T19:52:42+00:00

It wasn't a good idea to make the signal type a per-BSS option,
although then it is closer to the actual value. Move it to be
a per-wiphy setting, update mac80211 to match.

cfg80211/nl80211: scanning (and mac80211 update to use it)

2009-02-13T18:45:49+00:00

This patch adds basic scan capability to cfg80211/nl80211 and
changes mac80211 to use it. The BSS list that cfg80211 maintains
is made driver-accessible with a private area in each BSS struct,
but mac80211 doesn't yet use it. That's another large project.

cfg80211: Allow for strict regulatory settings

2009-01-29T21:01:18+00:00

This allows drivers to request strict regulatory settings to
be applied to its devices. This is desirable for devices where
proper calibration and compliance can only be gauranteed for
for the device's programmed regulatory domain. Regulatory
domain settings will be ignored until the device's own
regulatory domain is properly configured. If no regulatory
domain is received only the world regulatory domain will be
applied -- if OLD_REG (default to "US") is not enabled. If
OLD_REG behaviour is not acceptable to drivers they must
update their wiphy with a custom reuglatory prior to wiphy
registration.

cfg80211: pass more detailed regulatory request information on reg_notifier()

2009-01-29T21:01:17+00:00

Drivers may need more information than just who set the last regulatory domain,
as such lets just pass the last regulatory_request receipt. To do this we need
to move out to headers struct regulatory_request, and enum environment_cap. While
at it lets add documentation for enum environment_cap.
