wireless: update cfg80211 kconfig entry

2009-09-08T20:31:06+00:00

cfg80211 is now *the* wireless configuration API. Lets also
give a little explanation as to what it is and refer people to
the wireless wiki for more information.

cfg80211: make spurious warnings less likely, configurable

2009-08-28T18:40:30+00:00

Bob reported that he got warnings in IBSS mode about
the ssid_len being zero on a joined event, but only
when kmemcheck was enabled. This appears to be due
to a race condition between drivers and userspace,
when the driver reports joined but the user in the
meantime decided to leave the IBSS again, the warning
would trigger. This was made more likely by kmemcheck
delaying the code that does the check and sends the
event.

So first, make the warning trigger closer to the
driver, which means it's not locked, but since only
the warning depends on it that's ok.

And secondly, users will not want to have spurious
warnings at all, so make those that are known to be
racy in such a way configurable.

cfg80211: implement iwpower

2009-07-10T19:01:51+00:00

Just on/off and timeout, and with a hacky cfg80211 method
until we figure out what we want, though this is probably
sufficient as we want to use pm_qos for wifi everywhere.

cfg80211: introduce nl80211 testmode command

2009-07-10T19:01:50+00:00

This introduces a new NL80211_CMD_TESTMODE for testing
and calibration use with nl80211. There's no multiplexing
like like iwpriv had, and the command is not available by
default, it needs to be explicitly enabled in Kconfig and
shouldn't be enabled in most kernels.

The command requires a wiphy index or interface index to
identify the device to operate on, and the new TESTDATA
attribute. There also is API for sending replies to the
command, and testmode multicast messages (on a testmode
multicast group).

I've also updated mac80211 to be able to pass through the
command to the driver, since it itself doesn't implement
the testmode command.

Additionally, to give people an idea of how to use the
command, I've added a little code to hwsim that makes use
of the new command to set the powersave mode, this is
currently done via debugfs and should remain there, and
the testmode command only serves as an example of how to
use this best -- with nested netlink attributes in the
TESTDATA attribute. A hwsim testmode tool can be found at
http://git.sipsolutions.net/hwsim.git/. This tool is BSD
licensed so people can easily use it as a basis for their
own internal fabrication and validation tools.

wext: default to y

2009-07-10T19:01:48+00:00

The way I initially thought we could do wireless extensions
is by making all the compat code in cfg80211 be independent
of CONFIG_WIRELESS_EXT, but this is turning out to not be
feasible. Therefore, fix the Kconfig help text and make the
option default to yes, so people won't get a nasty surprise
when mac80211 will get rid of its 'select WIRELESS_EXT' any
time now.

cfg80211: add rfkill support

2009-06-03T18:06:14+00:00

To be easier on drivers and users, have cfg80211 register an
rfkill structure that drivers can access. When soft-killed,
simply take down all interfaces; when hard-killed the driver
needs to notify us and we will take down the interfaces
after the fact. While rfkilled, interfaces cannot be set UP.

mac80211/cfg80211: move wiphy specific debugfs entries to cfg80211

2009-05-20T18:46:23+00:00

This moves the cfg80211 specific stuff to new cfg80211 debugfs
entries. Non-mac80211 will also get these entries now. There were
only 4 which we take:

rts_threshold
fragmentation_threshold
short_retry_limit
long_retry_limit

cfg80211/nl80211: remove usage of CONFIG_NL80211

2009-03-28T00:12:42+00:00

The scan capability added to cfg80211/nl80211 introduced a
dependency on nl80211 by cfg80211. We can thus no longer have
just cfg80211 without nl80211. Specifically, cfg80211_scan_done()
calls nl80211_send_scan_aborted() or nl80211_send_scan_done().

Now we remove the option for user to select nl80211. It will always
be compiled if user selects cfg80211.
