83b83b461d nl80211: Migrate to current netlink key message format
Linux 2.6.32 (December 2009) introduced alternate netlink messages
for setting and installing keys, deprecating the older ones.

To allow hostapd/wpa_supplicant to use new features only provided via
the new API this patch migrates all netlink messages to the current ones.

Since the nl80211 driver was sometimes already using the new format this
is only unifying the netlink API usage and not changing the minimal
kernel requirement.

The following netlink attributes have been retired for key installs:

  NL80211_ATTR_KEY_DATA
  NL80211_ATTR_KEY_TYPE
  NL80211_ATTR_KEY_SEQ
  NL80211_ATTR_KEY_IDX
  NL80211_ATTR_KEY_CIPHER
  NL80211_ATTR_KEY_DEFAULT
  NL80211_ATTR_KEY_DEFAULT_MGMT
  NL80211_ATTR_KEY_DEFAULT_TYPES

And replaced by the following attributes nested in NL80211_ATTR_KEY:

  NL80211_KEY_DATA
  NL80211_KEY_TYPE
  NL80211_KEY_SEQ
  NL80211_KEY_IDX
  NL80211_KEY_CIPHER
  NL80211_KEY_DEFAULT
  NL80211_KEY_DEFAULT_MGMT
  NL80211_KEY_DEFAULT_TYPES

When getting Michael MIC failure notifications or querying a key
sequence number the kernel continues to use the old attributes:
  NL80211_ATTR_KEY_TYPE
  NL80211_ATTR_KEY_SEQ
  NL80211_ATTR_KEY_IDX

7a4b01c879 AP: Provide correct keyid to wpa_send_eapol() for EAPOL-Key msg 3/4
PTKINITNEGOTIATING in the WPA state machine calls wpa_send_eapol() and
hands over the GTK instead of the PTK keyid.

Besides a confusing debug message this does not have any negative side
effects: The variable is only set to a wrong value when using WPA2 but
then it's not used.

With this patch PTKINITNEGOTIATING sets the PTK keyid unconditionally to
zero for EAPOL-Key msg 3/4 and differentiates more obviously between GTK
and PTK keyids.

d9286d0997 ACS: Stop before scan if no channels in chanlist are available
When we set "channel=0" in hostapd.conf to enable ACS function, and set
a wrong channel list, e.g., chanlist=222-999 on purpose, hostapd would
still start ACS process to compute the ideal channel, even when there
are no available channels with such configuration.

Though there is no problem since hostapd fails to initialize interface,
it spends time going through the scan and the debug log entries may make
it more difficult to tell what was behind the failure.

Thus, check if there are any available channels in acs_request_scan(),
and return -1 if no available channel, then it will fail at acs_init(),
without doing ACS computation. It will show the following in the log:
    Could not select hw_mode and channel. (-3)
    wlan0: interface state UNINITIALIZED->DISABLED

Then we can know the setting is incorrect already in
hostapd_select_hw_mode(), instead of waiting for scan callback function
to know if the setting is ok for ACS or not. This can save time and help
to tell if the setting is correct at the initial function at the first.
This will also allow the ENABLE control interface command to return FAIL
when adding an interface dynamically.

3394def5a8 More consistent SA check for unexpected Data frames
Use the same rules for dropping driver notifications for Data frames
from unassociated stations as were added for Management frame reception.
This results in more consistent behavior in sending out Deauthentication
frames with Reason Code 6/7.

This case was already checking for unexpected multicast addresses, so
there was no issue for the PMF protections for unexpected disconnection.
Anyway, better avoid unnecessary Deauthentication frames consistently.

b10e01a795 DPP2: Connection status result (Configurator)
A new argument to the DPP_AUTH_INIT command (conn_status=1) can now be
used to set Configurator to request a station Enrollee to report
connection result after a successfully completed provisioning step. If
the peer supports this, the DPP-CONF-SENT event indicates this with a
new argument (wait_conn_status=1) and the Configurator remains waiting
for the connection result for up to 16 seconds.

Once the Enrollee reports the result, a new DPP-CONN-STATUS-RESULT event
is generated with arguments result, ssid, and channel_list indicating
what the Enrollee reported. result=0 means success while non-zero codes
are for various error cases as specified in the DPP tech spec. If no
report is received from the Enrollee, the event with "timeout" argument
is generated locally.

018edec9b2 Remove IAPP functionality from hostapd
IEEE Std 802.11F-2003 was withdrawn in 2006 and as such it has not been
maintained nor is there any expectation of the withdrawn trial-use
recommended practice to be maintained in the future. Furthermore,
implementation of IAPP in hostapd was not complete, i.e., only parts of
the recommended practice were included. The main item of some real use
long time ago was the Layer 2 Update frame to update bridges when a STA
roams within an ESS, but that functionality has, in practice, been moved
to kernel drivers to provide better integration with the networking
stack.

d86d66dc07 AP: Silently ignore management frame from unexpected source address
Do not process any received Management frames with unexpected/invalid SA
so that we do not add any state for unexpected STA addresses or end up
sending out frames to unexpected destination. This prevents unexpected
sequences where an unprotected frame might end up causing the AP to send
out a response to another device and that other device processing the
unexpected response.

In particular, this prevents some potential denial of service cases
where the unexpected response frame from the AP might result in a
connected station dropping its association.
