d8816397c3 nl80211: Remove WEXT Michael MIC event processing
mac80211 does not use this type of Michael MIC event, so this is not
really used and proper Michael MIC failure processing will be added
using an nl80211 event once that gets added into wireless-testing.git.

e8a029fb6d nl80211: Remove WEXT_COMPAT
It looks like both new nl80211 operations (scan and auth/assoc) end up
being added in Linux 2.6.30, so we do not need to maintain the backwards
compatibility code in wpa_supplicant.

d3a9822542 Add support for specifying subset of enabled frequencies to scan
A new network block parameter, scan_freq, can be used to specify subset
of frequencies to scan. This can speed up scanning process considerably
if it is known that only a small subset of channels is actually used in
the network. A union of configured frequencies for all enabled network
blocks is used in scan requests.

Currently, only driver_nl80211.c has support for this functionality.

For example, following parameter marks 2.4 GHz channels 1, 6, 11 to be
scanned: scan_freq=2412 2437 2462

36b15723ca Deprecate set_drop_unencrypted(), set_auth_alg(), and set_mode()
All these driver handlers can be implemented in associate() handler
which gets all the needed information in the parameters structure. The
old functions that provided only a single parameter will be removed
eventually to clean up the driver_ops structure, so driver wrappers
should start using the newer mechanism.

c2a0407851 Add SME support (separate authentication and association)
This can be used, e.g., with mac80211-based Linux drivers with
nl80211. This allows over-the-air FT protocol to be used (IEEE
802.11r).

Since the nl80211 interface needed for this is very recent (added
today  into wireless-testing.git), driver_nl80211.c has backwards
compatibility code that uses WEXT for association if the kernel does
not support the new commands. This compatibility code can be
disabled by defining NO_WEXT_COMPAT. That code will also be removed
at  some point to clean up driver_nl80211.c.

babfbf15cc FT: Add RIC Request generation and validation (but not processing)
This adds first part of FT resource request as part of Reassocition
Request frame (i.e., FT Protocol, not FT Resource Request Protocol).
wpa_supplicant can generate a test resource request when driver_test.c
is used with internal MLME code and hostapd can verify the FTIE MIC
properly with the included RIC Request.

The actual RIC Request IEs are not processed yet and hostapd does not
yet reply with RIC Response (nor would wpa_supplicant be able to
validate the FTIE MIC for a frame with RIC Response).

This is done with wired interfaces to fix IEEE 802.1X authentication

This allows wpa_supplicant to complete wired authentication successfully
on Vista with a NDIS 6 driver, but the change is likely needed for
Windows XP, too.

80bc75f135 New driver capability info: max number of scan SSIDs
The driver wrappers can now inform wpa_supplicant how many SSIDs can
be used in a single scan request (i.e., send multiple Probe Requests
per channel). This value is not yet used, but it can eventually be used
to allow a new scan command to specify multiple SSIDs to speed up
scan_ssid=1 operations. In addition, a warning could be printed if
scan_ssid=1 is used with a driver that does not support it
(max_scan_ssids=0).

e1b525c356 Use signal quality if level is not available for comparing max rates
Some drivers (for example ipw2100) do not report signal level but only
signal quality. wpa_supplicant already uses the signal quality if no
level is reported and all other comparision parameters are equal to sort
the scan results. However, if two APs have different max rates and the
signal level does not differ much wpa_supplicant chooses the AP with the
higher max rate.

In case of ipw2100 no signal level is reported and thus wpa_supplicant
always takes the AP with higher max rate even if its signal quality is
really low. For example if AP1 (max rate 11Mb/s, 80% signal quality) and
AP2 (max rate 54 Mb/s, 20% signal quality) are found by a scan
wpa_supplicant would choose AP2.

Hence, if no signal level is reported depend on the signal quality if
max rate should be compared. A quality difference of 10% is considered
acceptable in favor of the higher max rate.

b965fa7294 wext: really disassociate (set random SSID)
Really disassociate when tearing stuff down; drivers may sometimes
(legally) keep trying to reassociate unless the BSSID is unlocked.  If
the SSID is unlocked too, under WEXT drivers are able to pick an SSID to
associate, so kill that behavior by setting a bogus SSID.  Unfortunately
WEXT doesn't provide an easy method to say "stop whatever doing and just
idle".

42f1ee7d1f Fixed scan buffer increasing with WEXT
We can now handle up to 65535 byte result buffer which is the maximum
due to WEXT using 16-bit length field. Previously, this was limited to
32768 bytes in practice even through we tried with 65536 and 131072
buffers which we just truncated into 0 in the 16-bit variable.

This more or less doubles the number of BSSes we can received from scan
results.

94abc2f11b Better support in RoboSwitch driver
I am terribly sorry, but because of a lack of testing equipment the
patch was submitted not properly tested.
Because the chipset documentation is not publicly available all
behaviour has to be found out by experimentation. The other day, I
made some incorrect assumptions based on my findings.

I do believe the attached patch does support the whole RoboSwitch line
(5325, 5350, 5352, 5365 and others). It is a drop-in substitution for
my previous submission.

c0a0c97aa9 Better support in RoboSwitch driver
The RoboSwitch driver of wpa_supplicant had one shortcoming: not
supporting the 5365 series. I believe the patch attached fixes this

Furthermore it contains a small readability rewrite. It basically is an
explicit loop-rollout so that the wpa_driver_roboswitch_leave style
matches that of wpa_driver_roboswitch_join.

wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.

e519314ee9 Add RoboSwitch driver interface for wpa_supplicant
Find attached the patch that creates a new driver: roboswitch. This
driver adds support for wired authentication with a Broadcom
RoboSwitch chipset. For example it is now possible to do wired
authentication with a Linksys WRT54G router running OpenWRT.

LIMITATIONS
- At the moment the driver does not support the BCM5365 series (though
adding it requires just some register tweaks).
- The driver is also limited to Linux (this is a far more technical
restriction).
- In order to compile against a 2.4 series you need to edit
include/linux/mii.h and change all references to "u16" in "__u16". I
have submitted a patch upstream that will fix this in a future version
of the 2.4 kernel. [These modifications (and more) are now included in
the kernel source and can be found in versions 2.4.37-rc2 and up.]

USAGE
- Usage is similar to the wired driver. Choose the interfacename of
the vlan that contains your desired authentication port on the router.
This name must be formatted as <interface>.<vlan>, which is the
default on all systems I know.

b6310a6f47 NDIS: Set authMode=WPA2, if needed, when flushing PMKID cache
Some drivers may refuse OID_802_11_PMKID if authMode is not set to WPA2,
so let's set it temporarily, if needed, when flushing PMKID cache.

ec5f180a24 Add an optional set_mode() driver_ops handler for setting mode before keys
A bug just got reported as a result of this for mac80211 drivers.

https://bugzilla.redhat.com/show_bug.cgi?id=459399

The basic problem is that since taking the device down clears the keys
from the driver on many mac80211-based cards, and since the mode gets
set _after_ the keys have been set in the driver, the keys get cleared
on a mode switch and the resulting association is wrong.  The report is
about ad-hoc mode specifically, but this could happen when switching
from adhoc back to managed mode.

fd630bc183 Fixed WEXT scan result parser to not crash on invalid IEs (zero len buffer)
If IWEVGENIE or custom event wpa_ie/rsn_ie is received in scan with empty
buffer, the previous version ended up calling realloc(NULL, 0) which seems
to return a non-NULL value in some cases. When this return value is passed
again into realloc with realloc(ptr, 0), the returned value could be NULL.
If the ptr is then freed (os_free(data.ie) in SIOCGIWAP handling), glibc
may crash due to invalid pointer being freed (or double-freed?). The
non-NULL realloc(NULL, 0) return value from glibc looks a bit odd behavior,
but anyway, better avoid this case completely and just skip the IE events
that have an empty buffer.

This issue should not show up with drivers that produce proper scan results
since the IEs will always include the two-octet header. However, it seems
to be possible to see this when using 64-bit kernel and 32-bit userspace
with incorrect compat-ioctl processing.

3c83f19c80 Added mlme_{add,remove}_sta() for userspace MLME
These functions are based on the hostapd implementation and complete
the userspace MLME code in wpa_supplicant (though, mac80211 will still need
couple of pending patches to be integrated in order to get userspace client

This adds some parts needed to use usermode MLME with the current mac80211
(plus a patch to add a new cfg80211 command; not yet submitted to
wireless-testing). This version creates a monitor interface for management
frames and is able to send Probe Request frames during scan. However, it
looks like management frame reception is not yet working properly. In
addition, mlme_{add,remove}_sta() handlers are still missing.

7524cfb1a3 nl80211: Fixed re-initialization of removed and re-inserted interface
Network device ifindex will change when the interface is re-inserted.
driver_nl80211.c will need to accept netlink events from "unknown" (based
on ifindex) interfaces when a previously used card was removed earlier. If
the previously removed interface is added back, the driver_wext data need
to be updated to match with the new ifindex value. In addition, the initial
setup tasks for the card (set interface up, update ifindex, set mode, etc.)
from wpa_driver_nl80211_init() need to be run again.

This is the changes from commit 3fbda8f943

93ef879f0f wext: fix maxrate calculation
When scan results got moved from wpa_scan_result -> wpa_scan_res, the
'maxrate' member was dropped from wpa_scan_res.  The D-Bus interface
used 'maxrate', which was replaced with wpa_scan_get_max_rate().
Unfortunately, wpa_scan_get_max_rate() returns 802.11 rate values
directly from the IE, where 'maxrate' was the rate in bits/second.  The
supplicant internally fakes an IE for wpa_scan_res from the value of
wpa_scan_result->maxrate, but interprets ->maxrate as an 802.11 rate
index.

As a side-effect, this fixes a soft-break of the D-Bus control API since
the wpa_scan_res change was introduced.

59c9707863 wext: handle mode switches correctly for mac80211
Since mac80211 requires that the device be !IFF_UP to change the mode
(and I think the old prism54 fullmac driver does too), do that.  This
shouldn't harm fullmac devices since they can handle mode switches on
the fly and usually don't care about up/down that much.

2e5a7b49a0 wext: don't overwrite BSS frequency
mac80211 sends _both_ channel and frequency in it's scan results, with
frequency first and channel second (it's since been fixed to send
channel first and frequency second to work around this issue).  This
results in wpa_supplicant getting the right value when the frequency
comes, but overwriting the value with '0' when the channel comes because
wpa_supplicant can't handle 5GHz channel numbers.  So if a valid
previous SIOCGIWFREQ event came in, don't try to overwrite it.

b5a357b476 Add support for PS3 Linux wireless driver
This adds support for PS3 wireless to wpa_supplicant.

Although PS3 wireless driver is designed to conform the WEXT standard
as much as possible, unfortunately the wext driver wrapper of
wpa_supplicant can not support PS3 wireless fully because:

 - PS3 wireless driver uses private WEXT ioctls for accepting PSK of
   WPA-Personal from the userland.
   WEXT does not specify the way to do it.

 - The association and 4-way handshake are done by PS3 virtual
   wireless device. The guest OSes can not interfere it.

 - No EAPOL frames are allowed to go outside of the
   hypervisor/firmware nor come from. They are eaten by the firmware.

Thus I needed to make a new driver wrapper for PS3 wireless.

This patch can be applied against the latest 0.6.x tree.
