Instead of calling specific Probe Request handler functions, use a
generic mechanism that allows multiple callback functions to be
registered for getting notification on receive Probe Request frames.
The driver wrappers should not need to include wps_hostapd.h, so let's
make this easier by introducing a driver callback for reporting Probe
Request frames.
Since we do not currently support changing the AP settings received
from M7, there is no point in actually sending out the M8 that would
likely trigger the AP to reconfigure itself and potentially reboot.
For now, we just receive the AP settings in M7 and add a local network
configuration block based on those, but NACK the message. This makes
wps_reg work like wps_pin, but by using the AP PIN instead of a client
PIN.
Old way does not work with all drivers on NetBSD and FreeBSD are
also using this so should be a safe change. [Bug 312]

Add generic functions to get/set 80211 vars, set 80211 params and
get/sid ssid.
Change NetBSD defines to match the ioctl used for portability.
Check size we're copying into instead of assuming IFNAMSIZ.

If hostapd segfaults, or is killed with -9, or the interface already exists,
when the interface is created, it will fail.

Try to remove the interface and re-create it before aborting.
When the supplicant is connected and performs a scan, it doesn't enter
WPA_SCANNING state for various reasons. However, external programs
still need to know that the supplicant is scanning since they may not
wish to perform certain operations during a scan (as those operations
will likely fail or yield incorrect results). Add a 'scanning' property
and signal to the supplicant dbus interface to allow clients to
synchronize better with the supplicant when it scans.

To ensure the supplicant starts and ends with a clean slate (keys are
already cleaned up at init and deinit time), force a null BSSID and
bogus SSID to ensure the driver isn't connected to anything.

4853d5ac84 had a small bug in the order
of these function calls in _wext_deauthenticate() (_disassociate()
did have the correct order). The deauthentication frame is supposed
to go out (if driver supports that) before we disconnect more
forcefully.
Otherwise the driver might interpret the request as a request to
create/join a new adhoc network with the bogus SSID.

Previously, we would have allowed both the WPA and RSN EAPOL-Key
types to be used regardless of whether the association is using
WPA or RSN/WPA2. This shouldn't result in any significant problems
on the Authenticator side, but anyway, we should check the type and
ignore the EAPOL-Key frames that used unexpected type.
hostapd_cli wps_pin command can now have an optional timeout
parameter that sets the PIN lifetime in seconds. This can be used
to reduce the likelihood of someone else using the PIN should an
active PIN be left in the Registrar.
The attached patch will replace get_scan_results with get_scan_results2.
This is a preparation for WPS on BSD.
And I erased "wpa_scan_result_compar". Because scan result
sorting will be done with "wpa_scan_result_compar" on
"scan_helpers.c".
I have done below tests on NetBSD with an atheros card.
- WPA2-PSK(CCMP)
- WPA-PSK(TKIP)
- PEAP(MSCHAPv2)
- EAP-TLS
- EAP-TTLS(MSCHAPv2)
This adds a cleaner mechanism for protecting against unauthorized
data frames than the previously used drop_unencrypted mechanism
(which is not even available with nl80211 and had to use a WEXT
ioctl.
The old drop_unencrypted code is left in for now as the final
surviving WEXT use in driver_nl80211.c. However, it can be removed
from the build by defining NO_WEXT. It may also be removed
eventually when most users are expected to be using recent enough
kernel version.
For now, the old code using NL80211_ATTR_STA_FLAGS is left in for
backwards compatibility with older kernel versions. It may be removed
eventually when most users are expected to be running with new
enough kernel version.
We could use auto-channel selection here eventually, but for now,
reject the configuration since it is not going to work correctly
(Beacon and Probe Response frames use incorrect value in DS Params).
I've exported the methods wpsPbc, wpsReg and wpsPin (patch attached),
so wpa_supplicant should be able to connect with WPS using the dbus
interface. I couldn't test it well because the problem seems to be in
my wireless card, a Broadcom BCM4328. At least it seems to do the same
using both interfaces. With ndiswrapper driver the "wpsie" entry
(thanks Dan!) didn't appear, and with the Broadcom wl driver it
appears but I cannot associate using WPS.
Add a new DBus method "setDebugParams" which takes the parameters
debug_level, debug_timestamp and show_keys as input and updates the
internal debug variables accordingly.
To change the debug level, enable/disable timestamps and enable/disable
show_keys the following dbus-send command can be used:
dbus-send --system --dest=fi.epitest.hostap.WPASupplicant --print-reply
/fi/epitest/hostap/WPASupplicant fi.epitest.hostap.WPASupplicant.setDebugParams

Port the code from wpa_supplicant to re-use an existing ctrl_iface
socket file if the file does not seem to be in use. This allows
hostapd to recover from unclean shutdown of the control interface.
Some deployed implementations seem to advertise incorrect information
in this attribute. For example, Linksys WRT350N seems to have a
byteorder bug that breaks this negotiation. In order to interoperate
with existing implementations, assume that the Enrollee supports
everything we do.
Attached is a patch for the RoboSwitch driver in trunk. It is a
general revision of the source code.
Changes:
- Improved IEEE 802.1X conformance ([1])
- Better conformity to Broadcom specifications
- Fixed compatibility with different chipset revisions
It is worth noting that performance may drop a little using the new
driver. This can be overcome by using "multicast_only=1" as a
parameter. In that case only packets to the PAE group address are
regarded, as the previous revision of the driver did. A more detailed
description of the parameter and it's consequences is available at [2]
(summary: use "multicast_only=1" whenever possible).

None of the driver wrappers user this. hostapd-controlled broadcast SSID
hiding can only be used with drivers that use hostapd for handling
Beacon and Probe Request/Response frames.
None of the driver wrappers use this. Only the drivers that use hostapd
for Beacon and Probe Request/Response handling can now use IEEE 802.11d
properly.
Note: This changes values for existing NL80211_ATTR_MAX_SCAN_IE_LEN
and NL80211_ATTR_KEY_TYPE (for some reason, they ended up getting
swapped in wireless-testing.git) and as such, could break Michael
MIC error reporting (well, at least partially).
When in AP mode, wpa_supplicant is now enabling WPS (only Internal
Registrar). wpa_cli wps_pbc and wps_pin commands can be used to initiate
WPS negotiation similarly to how this is done in station mode (though,
the BSSID parameter is ignored).
