7f6400ed19 Make sha256_process() easier for static analyzers
md->curlen cannot indicate full buffer size here since the buffered
data is processed whenever the full block size of data is available.
Avoid invalid warnings from static analyzers on memcpy() outside the
buffer length by verifying that curlen is smaller than block size.

3724ddc0c1 PEAP: Verify peap_prfplus() result
This function can fail in theory since the SHA-1 functions are
allowed to return an error. While this does not really happen in
practice (we would not get this far if SHA-1 does not work), it is
cleaner to include the error handling here to keep static analyzers
happier. [Bug 421]

Without this patch, after the 7th message you got the WPS-CRED-RECEIVED

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

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.

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

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.

c48183fca2 For MS-CHAP, convert the password from UTF-8 to UCS-2
The MS-CHAPv1 and MS-CHAPv2 RFCs specify that the password is a string

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
EncryptPwBlockWithPasswordHash.

59d249255c nl80211: Ignore netlink interface down if interface is up
The netlink event processing is delayed since they are only returned
after control returns to eloop. This can result in netlink down events
being processed at a point when the interface has is actually still
there (the first event on new interface is down) and that can result in
odd behavior especially when the resulting interface-disabled event is
delivered to AP mode interface with wpa_supplicant.

Work around this by filtering netlink down events if the matching
interface is up at the time the netlink event is processed. This fixes
an issue brought up by commit 36d84860bb.

provided for connection.

Append P2P Device Address to AP-STA-CONNECTED event for P2P Client
connection. This will help applications to easily map the P2P Interface
Address to P2P Device Address on CONNECTED event. For non-P2P case, it
