cfg80211: remove CFG80211_REG_DEBUG

2016-01-14T10:13:09+00:00

Instead of having this Kconfig option, which just *floods* the
kernel log,
 * remove the per-channel prints that are fairly useless anyway
 * convert the conditional printing to pr_debug()

cfg80211: reg: make CRDA support optional

2015-10-16T07:15:39+00:00

If there's a built-in regulatory database, there may be little point
in also calling out to CRDA and failing if the system is configured
that way. Allow removing CRDA support to save ~1K kernel size.

cfg80211: don't allow disabling WEXT if it's required

2015-04-08T07:19:29+00:00

The change to only export WEXT symbols when required could break
the build if CONFIG_CFG80211_WEXT was explicitly disabled while
a driver like orinoco selected it.

Fix this by hiding the symbol when it's required so it can't be
disabled in that case.

cfg80211-wext: export symbols only when needed

2015-02-28T20:31:09+00:00

When a fully converted cfg80211 driver needs cfg80211-wext for
userspace API purposes, the symbols need not be exported. When
other drivers (orinoco/hermes or ipw2200) are enabled, they do
need the symbols exported as they use them directly.

Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig
symbol (instead of just CFG80211_WEXT) and export the functions
only if requested - this saves about 1/2k due to the size of
EXPORT_SYMBOL() itself.

Revert "cfg80211: make WEXT compatibility unselectable"

2014-12-31T00:42:29+00:00

This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a.

It's causing severe userspace breakage.  Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore.  There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.

Please see [1] for example of the userspace breakage this is causing.

In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.

To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

cfg80211: make WEXT compatibility unselectable

2014-11-28T11:21:34+00:00

This option has been marked for deprecation and removal for
a little more than two years, but it's not been very clearly
signalled since it was always possible to just select it.

Make it unselectable now to signal anyone who's still using
it after all this time more clearly. They can still get it
back, but only by patching the kernel.

wireless: fixup genregdb.awk for remove of antenna gain from wireless-regd

2014-07-21T10:24:20+00:00

Since "wireless-regdb: remove antenna gain" was merged in the
wireless-regdb tree, the awk script parser has been incompatible
with the 'official' regulatory database.  This fixes that up.
Without this change the max EIRP is set to 0 making 802.11 devices
useless.

The fragile nature of the awk parser must be replaced, but ideas
over how to do that in the most scalable way are being reviewed.
In the meantime update the documentation for CFG80211_INTERNAL_REGDB
so folks are aware of expectations for now.

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: Add Kconfig option for cellular BS hints

2014-04-09T08:55:33+00:00

Move the regulatory cellular base station hints support under
a specific configuration option and make the option depend
on CFG80211_CERTIFICATION_ONUS.
