618f5d01b0 hostapd: Add INTERFACES ctrl_iface command
Return a list of the available interfaces (the main BSS) and optionally
with ctrl_iface when the optional "ctrl" parameter is included. This is
useful when using UDP ctrl_iface and add interfaces using the ADD
command. After that we need to know which UDP port was assigned for the
control interface for the added interface.

b9066c638a hostapd: Allow UDP ctrl_iface configuration to set the UDP port
This allows the UDP port to be set for the per-interface and global

For example:
hostapd -ddt -g udp:8888

And in the configuration file:

c0e2a172a7 hostapd: Add MBO IE to BSS Transition Management Request frame
Add an option to add MBO IE to BSS Transition Management Request frame.
The MBO IE includes the transition reason code, cellular data connection
preference, and, if the disassoc imminent bit is set, it may also
include re-association retry delay. Otherwise, the re-association retry
delay should be set to zero.

The additional BSS_TM_REQ argument uses the following format:
mbo=<reason>:<reassoc delay>:<cell pref>
reason: 0-9
reassoc delay: 0-65535 (seconds; 0 = disabled)
cell pref: 0, 1, 255

fb9a1c3e28 hostapd: Add MBO IE to Beacon, Probe Response, Association Response
Add MBO IE with AP capability attribute to Beacon, Probe Response, and
(Re)Association Response frames to indicate the AP supports MBO.

Add option to add Association Disallowed attribute to Beacon, Probe
Response, and (Re)Association Response frames. Usage:

SET mbo_assoc_disallow <reason code>

Valid reason code values are between 1-5. Setting the reason code to
0 will remove the Association Disallowed attribute from the MBO IE
and will allow new associations.

MBO functionality is enabled by setting "mbo=1" in the config file.

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.

a65a9b8d67 hostapd: Add mechanism to track unconnected stations
hostapd can now be configured to track unconnected stations based on
Probe Request frames seen from them. This can be used, e.g., to detect
dualband capable station before they have associated. Such information
could then be used to provide guidance on which colocated BSS to use in
case of a dualband AP that operates concurrently on multiple bands under
the control of a single hostapd process.

a156ffda61 Add support for testing memory allocation failures
The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.

Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

A new control interface command, WNM_DEAUTH_REQ, is added for testing
purposes to allow the notification frame to sent based on local request.
This case does not disconnect the station automatically, i.e., a
separate control interface command would be needed for that.

ea449b5bfe tests: Add a module test integration to hwsim tests
CONFIG_MODULE_TESTS=y build option can now be used to build in module
tests into hostapd and wpa_supplicant binaries. These test cases will be
used to get better testing coverage for various details that are
difficult to test otherwise through the control interface control. A
single control interface command is used to executed these tests within
the hwsim test framework. This commit adds just the new mechanism, but no
module tests are yet integrated into this mechanism.

5bbf590a58 hostapd: Android: Force group access to ctrl_iface directory
Same fix as d49ea68284 in
wpa_supplicant.

From original commit:

wpa_supplicant is started from /init.*.rc on Android and that seems
to be using umask 0077 which would leave the control interface
directory without group access. This breaks things since Wi-Fi
framework assumes that this directory can be accessed by other
applications in the wifi group. Fix this by adding group access even
if umask value would prevent this.

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.

wps_nfc_dh_pubkey, wps_nfc_dh_privkey, and wps_nfc_dev_pw. This use
