5e0c20ff3e nl80211: Do not notify interface as re-enabled if initialization fails
wpa_supplicant tries to reinitialize an interface when a previously
removed netdev is restored (e.g., re-insert a USB dongle). If that
initialization fails (e.g., driver ejects ifconfig UP), the previous
implementation resulted in leaving the interface in incomplete state
while still claiming to upper layers that the interface status has
changed back to functional one.

Fix this by skipping the interface status update if reinitialization
fails. In other words, remain in INTERFACE_DISABLED state if the
interface cannot be re-enabled successfully.

115d5e2221 hostapd: Fix handling a 20/40 BSS Coexistence Management frame
hostapd processes a received 20/40 BSS Coexistence management frame, but
if no separate callbacks are registered for handling Public Action
frames it eventually sends a reply with MSB of category code set to 1
thinking that the received frame is an invalid frame. This could happen
based on whether hostapd was built and enabled with functionality using
the callback functions.

Fix this by explicitly returning 1 from the function when the 20/40 BSS
Coexistence Management frame is processed.

2d18ab4082 Add a config parameter to exclude DFS channels from ACS
The new acs_exclude_dfs=1 parameter can be used to request hostapd to
exclude all DFS channels from ACS consideration. This is mainly of use
for cases where the driver supports DFS channels, but for some reason a
non-DFS channel is desired when using automatic channel selection.
Previously, the chanlist parameter could have been used for this, but
that required listing all the acceptable channels. The new parameter
allows this to be done without such a list.

290834df69 nl80211: Fix race condition in detecting MAC change
Commit 3e0272ca00 ('nl80211: Re-read MAC
address on RTM_NEWLINK') added the detection of external changes to MAC
address when the interface is brought up.

If the interface state is changed quickly enough, wpa_supplicant may
receive the netlink message for the !IFF_UP event when the interface
has already been brought up and would ignore the next netlink IFF_UP
message, missing the MAC change.

Fix this by also reloading the MAC address when a !IFF_UP event is
received with the interface up, because this implies that the
interface went down and up again, possibly changing the address.

215eaa748b FILS: Implement FILS-FT derivation
This extends fils_pmk_to_ptk() to allow FILS-FT to be derived. The
callers do not yet use that capability; i.e., actual use will be added
in separate commits.

3a46cf93d0 FT: Add support for wildcard R0KH/R1KH
Enable use of FT RRB without configuring each other AP locally. Instead,
broadcast messages are exchanged to discover APs within the local
network.

When an R0KH or R1KH is discovered, it is cached for one day.

When a station uses an invalid or offline r0kh_id, requests are always
broadcast. In order to avoid this, if r0kh does not reply, a temporary
blacklist entry is added to r0kh_list.

To avoid blocking a valid r0kh when a non-existing pmk_r0_name is
requested, r0kh is required to always reply using a NAK. Resend requests
a few times to ensure blacklisting does not happen due to small packet
loss.

To free newly created stations later, the r*kh_list start pointer in
conf needs to be updateable from wpa_auth_ft.c, where only wconf is
accessed.

eefe863015 FT RRB: Add msg replay and msg delay protection
This adds a counter and adds sequence numbering to FT RRB packets. The
sequence number is checked against r0kh/r1kh sequence number cache.

Special attention is needed in case the remote AP reboots and thus loses
its state. I prefer it to recover automatically even without synchronized
clocks. Therefore an identifier called dom is generated randomly along the
initial sequence number. If the dom transmitted does not match or the
sequence number is not in the range currently expected, the sender is asked
for a fresh confirmation of its currently used sequence numbers. The packet
that triggered this is cached and processed again later.

Additionally, in order to ensure freshness, the remote AP includes an
timestamp with its messages. It is then verified that the received
messages are indeed fresh by comparing it to the older timestamps
received and the time elapsed since then. Therefore FT_RRB_TIMESTAMP is
no longer needed.

This assigns new OUI 00:13:74 vendor-specific subtype 0x0001 subtypes:
4 (SEQ_REQ) and 5 (SEQ_RESP).

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

245fc96e5f FT: New RRB message format
Convert FT RRB into a new TLV based format. Use AES-SIV as AEAD cipher
to protect the messages.

This needs at least 32 byte long keys. These can be provided either
by a config file change or letting a KDF derive the 32 byte key used
from the 16 byte key given.

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

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.

9f894823fa PAE: Silence static analyzer warning about NULL pointer dereference
ieee802_1x_kay_move_live_peer() did not check
ieee802_1x_kay_get_potential_peer() result explicitly and a static
analyzer reported a warning about the possible NULL result. This cannot
really happen in practice since the only caller of
ieee802_1x_kay_move_live_peer() verifies that the specific peer entry is
available. Anyway, it is easy to silence the false warning by adding an
explicit check here and cover any other potential case if another caller
is added.
