It is possible that the initialization of the Phase 2 EAP method fails and
if that happens, we need to stop EAP-TTLS server from trying to continue
using the uninitialized EAP method. Otherwise, the server could trigger
a segmentation fault when dereferencing a NULL pointer.
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 recent kernel change led to all EAPOL frames being encrypted rather than
just those for the group handshake. This is due to transmit processing in
the kernel now using the proper interface which would encrypt those frames
with the group key because hostapd wasn't requesting that they not be
encrypted. This changes the nl80211 driver to not request encryption unless
the EAPOL frame should be encrypted.

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 reverts the addition of ssl3_digest_cached_records() call from the
previous update (3d1aa251a3) since OpenSSL
has apparently reverted some earlier changes that broke EAP-FAST.
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.
Move the use of 802.11 header protocol field into driver_hostap.c since
this is a Host AP driver specific mechanism and other driver wrappers
should not really need to know about it.
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.
The tests directory and its subdirectories contain a set of configuration
files that can be used to exercise various mac80211, hostapd, and
wpa_supplicant features. The test.txt file in each test directory describes
the particular test and includes the commands needed to run the test.
This allows the accept_mac_file to be used as an alternative for RADIUS
server-based configuration. This is mainly to ease VLAN testing (i.e., no
need to set up RADIUS server for this anymore).
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.
sssleay.num had changed (new function allocated) and server code was
modified to call ssl3_digest_cached_records() in the start of abbreviated
handshake to avoid possible segmentation faults later in some cases when
reverting to full handshake. In addition, there is some whitespace cleanup
and added comment explaining TLS ticket processing.
When the TLS handshake had been completed earlier by the server in case of
abbreviated handshake, the output buffer length was left uninitialized. It
must be initialized to zero in this case. This code is used by EAP-FAST
server and the uninitialized length could have caused it to try to send a
very large frame (though, this would be terminated by the 50 roundtrip EAP
limit). This broke EAP-FAST server code in some cases when PAC was used to
establish the tunnel.
