941caed980 MBO: Add MBO ANQP-element processing on AP
This extends the GAS server to process MBO ANQP-elements and reply to a
query for the Cellular Data Connection Preference (if configured). The
new configuration parameter mbo_cell_data_conn_pref can be used to set
the value (0, 1, or 255) for the preference to indicate.

a1f11e34c4 Use os_memdup()
This leads to cleaner code overall, and also reduces the size
of the hostapd and wpa_supplicant binaries (in hwsim test build
on x86_64) by about 2.5 and 3.5KiB respectively.

The mechanical conversions all over the code were done with
the following spatch:

    expression SIZE, SRC;
    expression a;
    @@
    -a = os_malloc(SIZE);
    +a = os_memdup(SRC, SIZE);

ff936bc753 Make the third octet of Country String configurable
The new hostapd.conf parameter country3 can now be used to configure the
third octet of the Country String that was previously hardcoded to ' '
(= 0x20).

For example:

All environments of the current frequency band and country (default)
country3=0x20

Outdoor environment only
country3=0x4f

Indoor environment only
country3=0x49

Noncountry entity (country_code=XX)
country3=0x58

IEEE 802.11 standard Annex E table indication: 0x01 .. 0x1f
Annex E, Table E-4 (Global operating classes)
country3=0x04

206516e8c2 af_alg: Crypto wrappers for Linux kernel crypto (AF_ALG)
CONFIG_TLS=linux can now be used to select the crypto implementation
that uses the user space socket interface (AF_ALG) for the Linux kernel
crypto implementation. This commit includes some of the cipher, hash,
and HMAC functions. The functions that are not available through AF_ALG
(e.g., the actual TLS implementation) use the internal implementation
(CONFIG_TLS=internal).

c4bb39707f Fix AES-SIV build dependencies
aes-siv.c needs functions from aes-ctr.c and aes-omac1.c, so set
NEED_AES_CTR=y and NEED_AES_OMAC1=y if NEED_AES_SIV is defined. This

41f140d386 Add hostapd options wpa_group_update_count and wpa_pairwise_update_count
wpa_group_update_count and wpa_pairwise_update_count can now be used to
set the GTK and PTK rekey retry limits (dot11RSNAConfigGroupUpdateCount
and dot11RSNAConfigPairwiseUpdateCount). Defaults set to current
hardcoded value (4).

Some stations may suffer from frequent deauthentications due to GTK
rekey failures: EAPOL 1/2 frame is not answered during the total timeout
period of currently ~3.5 seconds. For example, a Galaxy S6 with Android
6.0.1 appears to go into power save mode for up to 5 seconds. Increasing
wpa_group_update_count to 6 fixed this issue.

34f7c699a6 Add multicast to unicast support
This adds support for nl80211 NL80211_CMD_SET_MULTICAST_TO_UNICAST
command.

By setting the new hostapd configuration option multicast_to_unicast=1,
hostapd configures this AP to perform multicast to unicast conversion.

When enabled, all multicast packets with ethertype ARP, IPv4, or IPv6
(possibly within an 802.1Q header) will be sent out to each station once
with the destination (multicast) MAC address replaced by the station's
MAC address. Note that this may break certain expectations of the
receiver, e.g., the ability to drop unicast IP packets encapsulated in
multicast L2 frames, or the ability to not send destination unreachable
messages in such cases.

This also does not implement Directed Multicast Service (DMS).

4ec1fd8e42 FT: Differentiate between FT for station and for AP in build
Previously, CONFIG_IEEE80211R enabled build that supports FT for both

station mode FT is required and there is no need for AP mode FT.

Add support to differentiate between station mode FT and AP mode FT in
wpa_supplicant builds by adding CONFIG_IEEE80211R_AP that should be used
when AP mode FT support is required in addition to station mode FT. This
allows binary size to be reduced for builds that require only the
station side FT functionality.

EAPOL-Key frames using an AEAD cipher (AES-SIV with FILS AKMs) before
processing the Key Data field. This replaces Key MIC validation for the
cases where AEAD cipher is used. This needs to move the EAPOL-Key msg
2/4 RSN element processing to happen only after the PTK has been derived
and validated. That is done for all AKMs to avoid extra complexity with
having to maintain two code paths for this.

96590564d6 FT: Allow PMK-R0 and PMK-R1 for FT-PSK to be generated locally
Station should be able to connect initially without ft_pmk_cache filled,
so the target AP has the PSK available and thus the same information as
the origin AP. Therefore neither caching nor communication between the
APs with respect to PMK-R0 or PMK-R1 or VLANs is required if the target
AP derives the required PMKs locally.

This patch introduces the generation of the required PMKs locally for
FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK.

So for FT-PSK networks, no configuration of inter-AP communication is
needed anymore when using ft_psk_generate_local=1 configuration. The
default behavior (ft_psk_generate_local=0) remains to use the pull/push
protocol.

04059ab844 Passive Client Taxonomy
Implement the signature mechanism described in the paper
"Passive Taxonomy of Wifi Clients using MLME Frame Contents"
published by Denton Gentry and Avery Pennarun.

http://research.google.com/pubs/pub45429.html
https://arxiv.org/abs/1608.01725

This involves:
1. Add a CONFIG_TAXONOMY compile option. Enabling taxonomy incurs
   a memory overhead of up to several kilobytes per associated
   station.
2. If enabled, store the Probe Request and (Re)Associate Request frame in
   struct sta_info.
3. Implement code to extract the ID of each Information Element,
   plus selected fields and bitmasks from certain IEs, into a
   descriptive text string. This is done in a new source file,
   src/ap/taxonomy.c.
4. Implement a "signature qq:rr:ss:tt:uu:vv" command
   in hostapd_cli to retrieve the signature.

Signatures take the form of a text string. For example, a signature
for the Nexus 5X is:
  wifi4|probe:0,1,127,45,191,htcap:01ef,htagg:03,htmcs:0000ffff,vhtcap:338061b2,
  vhtrxmcs:030cfffa,vhttxmcs:030cfffa,extcap:00000a0201000040|assoc:0,1,48,45,

Add configuration options that control publishing of fine timing

controlled by a location framework outside hostapd. When framework is

functionality. See IEEE P802.11-REVmc/D7.0, 9.4.2.27.

fc72a48a63 hostapd: Use stations nsts capability in (Re)Association Response frame
Some deployed stations incorrectly consider nsts capability in
(Re)Association Response frame as required capability instead of maximum
capability and if it is greater than station's capability then beamform
will not happen in uplink traffic.

This commit adds support for an optional workaround to use station's
nsts capability in (Re)Association Response frame if the station's nsts
is less than AP by using the use_sta_nsts=1 configuration parameter.
This configuration is introduced in this commit and it is disabled by
default.

d48d1b88d0 FT: Use BSSID as r1_key_holder if no value is configured
r1_key_holder is an identifier that was always set to zero if unless
configured before.

See 11.6.1.7.4 of IEEE Std 802.11-2012 which reads
 "R1KH-ID is a MAC address of the holder of the PMK-R1 in the
  Authenticator of the AP"
See 12.2.2 of IEEE Std 802.11-2012 which reads
 "Each R0KH-ID and R1KH-ID is assumed to be expressed as a unique
  identifier within the mobility domain."
 "The R1KH-ID shall be set to a MAC address of the physical entity
  that stores the PMK-R1 ..."

Defaulting this to BSSID is a more reasonable value since we have not
rejected the missing r1_key_holder as invalid configuration.

1889af2e0f VLAN: Separate station grouping and uplink configuration
Separate uplink configuration (IEEE 802.1q VID) and grouping of stations
into AP_VLAN interfaces.

The int vlan_id will continue to identify the AP_VLAN interface the
station should be assigned to. Each AP_VLAN interface corresponds to an
instance of struct hostapd_vlan that is uniquely identified by int
vlan_id within an BSS.

New: Each station and struct hostapd_vlan holds a struct
vlan_description vlan_desc member that describes the uplink
configuration requested. Currently this is just an int untagged IEEE
802.1q VID, but can be extended to tagged VLANs and other settings
easily.

When the station was about to be assigned its vlan_id, vlan_desc and
vlan_id will now be set simultaneously by ap_sta_set_vlan(). So
sta->vlan_id can still be tested for whether the station needs to be
moved to an AP_VLAN interface.

To ease addition of tagged VLAN support, a member notempty is added to
struct vlan_description. Is is set to 1 if an untagged or tagged VLAN
assignment is requested and needs to be validated. The inverted form
allows os_zalloc() to initialize an empty description.

Though not depended on by the code, vlan_id assignment ensures:
  * vlan_id = 0 will continue to mean no AP_VLAN interface
  * vlan_id < 4096 will continue to mean vlan_id = untagged vlan id
    with no per_sta_vif and no extra tagged vlan.
  * vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans.

This way struct wpa_group and drivers API do not need to be changed in
order to implement tagged VLANs or per_sta_vif support.

DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only,
thus grouping of the stations for per_sta_vif can be used with
DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct
hostapd_vlan is still used to manage AP_VLAN interfaces.

MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of
VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will
continue to refer to int vlan_id.

Renaming vlan_id to vlan_desc when type changed from int to struct
vlan_description was avoided when vlan_id was also used in a way that
did not depend on its type (for example, when passed to another
function).

Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN
%d" will refer to untagged IEEE 802.1q VID.

053693d266 hostapd: Add feature to start all interfaces at the same time in sync
When multiple interfaces across mutiple radios are started using a
single instance of hostapd, they all come up at different times
depending upon how long the ACS and HT scan take on each radio. This
will result in stations (that already have the AP profile) associating
with the first interfaces that comes up. For example in a dual band
radio case (2G and 5G) with ACS enabled, 2G always comes up first
because the ACS scan takes less time on 2G and this results in all
stations associating with the 2G interface first.

This feature brings up all the interfaces at the same time. The list of
interfaces specified via hostapd.conf files on the command line are all
marked as sync interfaces. All the interfaces are synchronized in
hostapd_setup_interface_complete().

This feature is turned on with '-S' commmand line option.
