Added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP
deficiencies. This can be set either by the Authenticator (to initiate
periodic 4-way handshake to rekey PTK) or by the Supplicant (to request
Authenticator to rekey PTK).
With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP
keys will not be used for more than 10 minutes which may make some attacks
against TKIP more difficult to implement.
This may be needed if the AP does not disconnect in case of EAP-FAST
unauthenticated provisioning (EAP-Failure). Adding the local short timeout
will speed up the process in such a case by reducing the wait (which can
often be up to 60 seconds).
This allows identity (etc.) variables to be removed from configuration
which is different from setting them to an empty string. For example,
EAP-SIM and EAP-AKA can now be configured to use identity string generation
from SIM/USIM by clearing the identity string in wpa_gui.
Setting the value of the SET_NETWORK command to NULL (without quotation)
unsets the variable, i.e., removes it from configuration file. This is
needed to allow GUI programs to clear variables, e.g., identity for
EAP-AKA/SIM.
Allow application to be started in the system tray only when started with
the `-t' command line argument.

When the system tray icon is created, qApp's setQuitOnLastWindowClosed
property is set to false, therefore do _not_ ignore widget close events, or
else wpa_gui will refuse to exit when the window manager is logging out.
While at it, remove WpaGui::fileExit() and connect fileExitAction to
quit().

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.
This function was getting way too long, so let's split it into WPA and
non-WPA cases as separate functions. In addition, remove the confusing
"Try to find non-WPA AP" debug message if a WPA-enabled AP is already
selected (as reported by Andriy Tkachuk).
but still show a one time tray message to indicate to the user that the
program is still running in the tray if they triggered the window manager
close button.

Do not connect lastWindowClosed() to quit(), instead explicitly close the
application if File->Exit or window manager close button is activated.
This allows the tray app to avoid being closed with last visible window,
and launch scan and event history windows individually.

When the initial scan is made, just the cached results from the driver
are used. If this is empty, it's useless to post the results since
another scan is being scheduled immediately. This just causes extra
processing from listeners for no gain.
The scan path to initiate another scan if the initial association failed
was broken due to wpa_s->scan_req being zeroed earlier in
wpa_supplicant_scan(). This caused the second scan to bail out early
since it thought this was not a requested scan.
Add system tray icon support to wpa_gui-qt4. The tray icon remains quiet
when the main dialog is visible, so it should not cause too much pain for
more conservative users of wpa_gui. The addition involves the following
changes:
* when closing wpa_gui via window manager close box, wpa_gui close event is
ignored and it is minimised to system tray. A status message is displayed
(or popup dialog box if tray messages are not supported) to provide a
visual hint that the program is still running in the background.
* add File->Exit slot handler to facilitate application quit from main
dialog
* provide a context menu with a short list of useful actions
* show/hide main dialog when icon is triggered (single click)
* ensure main dialog is visible when event handler or scan results is
chosen from tray icon context menu
* show tray messages on connected and disconnected events, display a status
message a few seconds after connected events

When integrating the new art, this UI entry:
<pixmapfunction>qPixmapFromMimeSource</pixmapfunction>
Caused the following error:
.obj/wpagui.o: In function `Ui_WpaGui::setupUi(QMainWindow*)':
wpagui.cpp:(.text._ZN9Ui_WpaGui7setupUiEP11QMainWindow[Ui_WpaGui::setupUi(QMainWindow*)]+0xd3): undefined reference to `qPixmapFromMimeSource(QString const&)'
collect2: ld returned 1 exit status
Removing qPixmapFromMimeSource seems to have no unwanted side effects, and
allows successful build again. Research leads me to believe it depends on
Qt3Support, which we do not want.

IEEE 802.11w/D6.0 defines new AKMPs to indicate SHA256-based algorithms for
key derivation (and AES-CMAC for EAPOL-Key MIC). Add support for using new
AKMPs and clean up AKMP processing with helper functions in defs.h.
This updates management frame protection to use the assocition ping process
from the latest draft (D6.0) to protect against unauthenticated
authenticate or (re)associate frames dropping association.
This adds most of the new frame format and identifier definitions from IEEE
802.11w/D6.0. In addition, the RSN IE capability field values for MFP is
replaced with the new two-bit version with MFPC (capable) and MFPR
(required) processing.
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.
