Abhijeet Kolekar 5f6120335c cfg80211: fix channel setting for wext
Patch fixes the bug at
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2139

Currently we cannot set the channel using wext extension
if we have already associated and disconnected. As
cfg80211_mgd_wext_siwfreq will not switch the channel if ssid is set.
This fixes it by clearing the ssid.
Following is the sequence which it tries to fix.
modprobe iwlagn
iwconfig wlan0 essid ""
ifconfig wlan0 down
iwconfig wlan0 chan X

wext is marked as deprecate.If we use nl80211 we can easily play with
setting the channel.

It is not clear to me how the first "direct probe" here
happens, but this seems to be a race condition, if the
user requests to deauth after requesting assoc, but before
the assoc response is received. In that case, it may
happen that mac80211 tries to report the assoc success to
cfg80211, but gets blocked on the wdev lock that is held
because the user is requesting the deauth.

The result is that we run into a warning. This is mostly
harmless, but maybe cause an unexpected event to be sent
to userspace; we'd send an assoc success event although
userspace was no longer expecting that.

To fix this, remove the warning and check whether the
race happened and in that case abort processing.

Alban Browaeys e60d7443e0 wireless : use a dedicated workqueue for cfg80211.
This patch moves the works cleanup, scan and events to a cfg80211
dedicated workqueue.

Platform driver like eeepc-laptop ought to use works to rfkill (as
new rfkill does lock in rfkill_unregister and the platform driver is
called from rfkill_switch_all which also lock the same mutex).
This raise a new issue in itself that the work scheduled by the platform
driver to the global worqueue calls wiphy_unregister which flush_work
scan and event works (which thus flush works on the global workqueue inside
a work on the global workqueue) and also put on hold the  wdev_cleanup_work
 (which prevents the dev_put on netdev thus indefinite Usage count error on
wifi device).

Johannes Berg a58ce43f2f mac80211: avoid spurious deauth frames/messages
With WEXT, it happens frequently that the SME
requests an authentication but then deauthenticates
right away because some new parameters came along.
Every time this happens we print a deauth message
and send a deauth frame, but both of that is rather
confusing. Avoid it by aborting the authentication
process silently, and telling cfg80211 about that.

The patch looks larger than it really is:
__cfg80211_auth_remove() is split out from
cfg80211_send_auth_timeout(), there's no new code
except __cfg80211_auth_canceled() (a one-liner) and
the mac80211 bits (7 new lines of code).

Johannes Berg ad4bb6f888 cfg80211: disallow bridging managed/adhoc interfaces
A number of people have tried to add a wireless interface
(in managed mode) to a bridge and then complained that it
doesn't work. It cannot work, however, because in 802.11
networks all packets need to be acknowledged and as such
need to be sent to the right address. Promiscuous doesn't
help here. The wireless address format used for these
links has only space for three addresses, the
 * transmitter, which must be equal to the sender (origin)
 * receiver (on the wireless medium), which is the AP in
   the case of managed mode
 * the recipient (destination), which is on the APs local
   network segment

In an IBSS, it is similar, but the receiver and recipient
must match and the third address is used as the BSSID.

To avoid such mistakes in the future, disallow adding a
wireless interface to a bridge.

Felix has recently added a four-address mode to the AP
and client side that can be used (after negotiating that
it is possible, which must happen out-of-band by setting
up both sides) for bridging, so allow that case.

It's very likely that not many devices will support
four-address mode in station or AP mode so introduce
capability bits for both modes, set them in mac80211

Also, keep track of 4addr in cfg80211 (wireless_dev)
and not in mac80211 any more. mac80211 can also be
improved for the VLAN case by not looking at the
4addr flag but maintaining the station pointer for
it correctly. However, keep track of use_4addr for
station mode in mac80211 to avoid all the derefs.

cfg80211 rejects all association requests when in associated state. This
prevents clean roaming within an ESS since one would first need to
disassociate before being able to request reassociation.

Accept the reassociation request and let the old association to be
dropped when the new one is completed. This fixes nl80211-based
roaming with the current snapshot version of wpa_supplicant (that has

attribute).

Holger Schurig 61fa713c75 cfg80211: return channel noise via survey API
This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey()
ops that a driver can implement. The goal of this command is to allow a
drivers to report channel survey data (e.g. channel noise, channel
occupation).

For now, only the mechanism to report back channel noise has been
implemented.

In future, there will either be a survey-trigger command --- or the existing
scan-trigger command will be enhanced. This will allow user-space to
request survey for arbitrary channels.

Note: any driver that cannot report channel noise should not report
any value at all, e.g. made-up -92 dBm.

Felix Fietkau f14543ee4d mac80211: implement support for 4-address frames for AP and client mode
In some situations it might be useful to run a network with an
Access Point and multiple clients, but with each client bridged
to a network behind it. For this to work, both the client and the
AP need to transmit 4-address frames, containing both source and
destination MAC addresses.
With this patch, you can configure a client to communicate using
only 4-address frames for data traffic.
On the AP side you can enable 4-address frames for individual
clients by isolating them in separate AP VLANs which are configured
in 4-address mode.
Such an AP VLAN will be limited to one client only, and this client
will be used as the destination for all traffic on its interface,
regardless of the destination MAC address in the packet headers.
The advantage of this mode compared to regular WDS mode is that it's
easier to configure and does not require a static list of peer MAC
addresses on any side.

Johannes Berg 584991dccf cfg80211: validate scan channels
Currently it is possible to request a scan on only
disabled channels, which could be problematic for
some drivers. Reject such scans, and also ignore
disabled channels that are given. This resuls in
the scan begin/end event only including channels
that are actually used.

This makes the mac80211 check for disabled channels
superfluous. At the same time, remove the no-IBSS
check from mac80211 -- nothing says that we should
not find any networks on channels that cannot be
used for an IBSS, even when operating in IBSS mode.

some people have been hitting for some reason -- the
params.bssid pointer is not guaranteed to be non-NULL
for what seems to be a race between various ways of
reaching the same thing.

While I'm trying to analyse the problem more let's
first fix the crash. I think the real fix may be to
avoid doing _anything_ if it ended up being NULL, but
right now I'm not sure yet.

I think
http://bugzilla.kernel.org/show_bug.cgi?id=14342
might also be this issue.

Johannes Berg 7bcfaf2f43 cfg80211/mac80211: use debugfs_remove_recursive
We can save a lot of code and pointers in the structs
by using debugfs_remove_recursive().

First, change cfg80211 to use debugfs_remove_recursive()
so that drivers do not need to clean up any files they
added to the per-wiphy debugfs (if and only if they are
ok to be accessed until after wiphy_unregister!).

Then also make mac80211 use debugfs_remove_recursive()
where necessary -- it need not remove per-wiphy files
as cfg80211 now removes those, but netdev etc. files
still need to be handled but can now be removed without
needing struct dentry pointers to all of them.

Holger Schurig e0da41b2cf cfg80211: remove warning in deauth case
It might be the case that __cfg80211_disconnected() has already
cleaned up wdev->current_bss() for us. The old code didn't catch
that situation and didn't warn needlessly.

Johannes Berg 7d930bc336 cfg80211: sme: deauthenticate on assoc failure
When the in-kernel SME gets an association failure from
the AP we don't deauthenticate, and thus get into a very
confused state which will lead to warnings later on. Fix
this by actually deauthenticating when the AP indicates
an association failure.

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!

Kalle Valo dfce95f51f cfg80211: add firmware and hardware version to wiphy
It's useful to provide firmware and hardware version to user space and have a
generic interface to retrieve them. Users can provide the version information
in bug reports etc.

Add fields for firmware and hardware version to struct wiphy.

(Dropped nl80211 bits for now and modified remaining bits in favor of
ethtool. -- JWL)
