0f0aa2a640 OCE: Move OCE checks to IE formation from hostapd initialization
Earlier, the OCE flags were checked during hostapd initialization. This
doesn't address few cases like for example when the interface is added
from control interface. Move the OCE flag checks to the functions that
are forming the MBO/OCE IEs to cover all the different paths for
enabling a BSS. Also use macros as appropriate for readability.

7eb6bfb45d DPP: Move hostapd Configurator/bootstrap data into global context
This moves the Configurator and Bootstrapping Information data from
struct hostapd_data (per-BSS) to struct hapd_interfaces (per-hostapd
process). This allows the information to be maintained over interface
restarts and shared between interfaces.

50bd8e0a90 FT: Replace inter-AP protocol with use of OUI Extended Ethertype
Replace the previously used extension of IEEE 802.11 managed Ethertype
89-0d (originally added for Remote Request/Response in IEEE 802.11r)
with Ethertype 88-b7 (OUI Extended EtherType) for FT inter-AP
communication. The new design uses a more properly assigned identifier
for the messages.

This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new
hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP),
and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH
protocol.

This breaks backward compatibility, i.e., hostapd needs to be updated on
all APs at the same time to allow FT to remain functional.

We can only send module specific messages to syslog and not debug

'-s' to allow it. The feature is enabled with compile flag

40f6282aed hostapd: Accept interface names as a command line parameter
This introduces an optinal command line parameter '-i' to override the
value of the 'interface' attribute in hostapd.conf files. This change
enables the reuse of the configuration files for the concurrent
instances of hostapd. An ability to dynamically assign the interface
names simplifies the usages of hostapd service in the automated

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.

354c903f8e AP/GO interface teardown optimization
This commit adds an option to optimize AP teardown by leaving the
deletion of keys (including group keys) and stations to the driver.

This optimization option should be used if the driver supports stations
and keys removal when stopping an AP.

For example, the optimization option will always be used for cfg80211
drivers since cfg80211 shall always remove stations and keys when
stopping an AP (in order to support cases where the AP is disabled
without the knowledge of wpa_supplicant/hostapd).

5afaa067d9 hostapd: Allow per-BSS (vif) configuration files
This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.

This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.
