613522a40a TLS: Fix block cipher padding validation
The padding validation was done on the last padding-length octets in the
buffer which misses the first padding octet (the last octet is the
padding length). Fix the starting offset for the comparison loop to get
the first octet verified. [Bug 420]

ignore unknown content types at record layer and allow processing to
continue after warning level TLS alerts to provide minimal workaround

39e7d718f6 ndis: Work around lack of C99 designated initializers in MSVC
Use a driver_ndis.c specific initialization function to fill in the
wpa_driver_ops information to make it easier to modify struct
wpa_driver_ops in the future. Being able to build driver_ndis.c
with MSVC was the only reason for having to maintain the same order
of function pointers in struct wpa_driver_ops and for having to
update driver_ndis.c for all changes in that structure.

wpa_supplicant_rsn_preauth_scan_results() needs to be called to

the wpa_supplicant_connect() call on the first association, but when

fbc72d32c6 Ignore Michael MIC failure reports if cipher is not TKIP
Some stations have been reported to send EAPOL-Key Error Reports
indicating Michael MIC failures even when the cipher is not TKIP
(e.g., when the network is using only CCMP). Ignore such reports
to avoid starting TKIP countermeasures unnecessarily. This can
prevent certaint types of denial of service attacks by insiders,
but mostly this is to work around invalid station implementations.

Control requests will be extended for non-EAP uses later, so it makes
sense to have them be generic. Furthermore, having them defined as an
enum is easier for processing internally, and more generic for control
interfaces that may not use field names. The public ctrl_req_type /
field_name conversion function will be used later by the D-Bus control
interface too.

d1dd48e3c9 P2P: Indicate scan during group formation as P2P probe
The interface may not yet have been set to P2P client mode immediately
after GO Negotiation when doing the scan before association request.
Consequently, the scan request in this state has to specify that the

Instead of hardcoding IEEE 802.11b rates to be disabled whenever
P2P support is built in and supported by the driver, do this only
when an interface is set to P2P mode (both when adding a new
interface and when changing the interface mode). This re-enables
use of IEEE 802.11b APs with CONFIG_P2P=y builds.

1dea5882be nl80211: Fix re-enabling of 802.11b rates
nl80211_disable_11b_rates() function was supposed to use the 'disabled'
parameter to figure out whether to disable or re-enable 802.11b rates.
In addition, the driver deinit path was now ending up re-disabling the
enabled rates at the end of the deinit operations when the interface
type was forced back to station. Both of these issues are now fixed
and the 2.4 GHz band TX rate index is cleared properly when
wpa_supplicant is stopped.

4483f23e15 dbus: Raise PropertiesChanged on org.freedesktop.DBus.Properties
wpa_supplicant dbus objects are currently difficult to use with
GDBusProxy. This is because they do not follow the dbus standard in
emitting the PropertiesChanged signal on the standard D-Bus properties
interface, so GDBusProxy stores stale property values.

Fix this by raising PropertiesChanged on the standard interface.
For backwards compatibility, the existing custom PropertiesChanged
signals are not removed; I anticipate them being removed in a future
major release.

c48183fca2 For MS-CHAP, convert the password from UTF-8 to UCS-2

password could be any even-length string of up to 512 bytes.

Instead of making the incompatible change of requiring the incoming
password to be UCS-2 encoded, assume the password is UTF-8 encoded and
convert it before using it in NtPasswordHash and
