8634e7343d mesh: Allow processing authentication frames in blocked state
If authentication fails repeatedly, e.g., because of a weak signal, the
link can end up in blocked state. If one of the nodes tries to establish
a link again before it is unblocked on the other side, it will block the
link to that other side. The same happens on the other side when it
unblocks the link. In that scenario, the link never recovers on its own.

To fix this, allow restarting authentication even if the link is in
blocked state, but don't initiate the attempt until the blocked period
is over. This reverts commit 09d96de09e ("mesh: Drop Authentication
frames from BLOCKED STA").

36bd75dfd2 hostapd: Fix channel switch to a DFS channel
When we are configuring automatic channel selection, we are not able to
switch to a given DFS channel because when we are trying to move to a
DFS channel, the interface is disabled and enabled again. When the
interface is disabled and enabled we are setting iface's freq and
channel to 0 in setup_interface2() in case ACS is enabled, and now we
don't know to which channel we were trying to move. Now ACS will run and
the interface will be up in the channel that is suitable.

To fix this issue add a flag named is_ch_switch_dfs to check if the
channel switch request is for a DFS channel and we can use this in
setup_interface2() to decide whther we have to set iface's freq and
channel to 0 or not. This way iface's freq and channel will retain the
values while channel switching to a DFS channel when ACS is enabled.

f4b84ecaf7 AP MLD: Track radar detection in offloaded DFS case
Add a new flag radar_detected which is used in the following cases
when setting up a link on a DFS channel while the interface is not yet
enabled:
    1. DFS link received CAC start event
    2. If no radar detected, link setup succeeeds after CAC end
       event is received. Else go to 3.
    3. Radar detected on this link -> set radar_detected bit
    4. CAC end received for the current freq -> Do not setup interface
       as radar already detected. Clear radar_detected bit.
    5. The driver sends channel switch event to switch to another channel
        a. Switch to another DFS channel -> go to 1
        b. Switch to non-DFS channel -> proceed to set up interface

Or when receiving a CAC start event when the interface is already set up:
    1. DFS link already set up successfully
    2. Radar detected on this link -> set radar_detected bit
       a. Switch to DFS channel
           a.1. CAC start -> clear radar_detected bit and partner RNR
           a.2. If radar detected, go to 2.
           a.3. CAC end -> clear radar_detected bit

9fdbaf2ed6 AP MLD: Fix advertisement of MLD capabilities
Previously, hostapd directly advertised the MLD capabilities received
from the driver. Since this information is exchanged during
initialization time only, the driver will advertise the maximum
supported values. hostapd should parse it and then based on the current
situation fill the values accordingly.

For example, the maximum number of simultaneous links is supposed to be
a value between 0 and 14, which is the number of affiliated APs minus 1.
The driver advertises this value as 5 and hostapd, irrespective of the
current active links, puts 5 in the frames.

Fix this by parsing the value from the driver capabilities and then
using the values as per the current situation of the links. The
advertised values will be used as the upper limit.

60e1dca1ef AP MLD: Clean up MLD when not required any further
Currently, whenever a new BSS is created, if it is an EHT BSS it is tied
to a corresponding MLD structure. If the structure does not exist
already, a new one is created and tied to it. Accordingly, the link ID
is assigned as well. However, when the BSS is deleted, the MLD structure
is not freed and when it is again created the next time, the link ID is
incremented further and the BSS gets a wrong link ID.

For example, 2.4 GHz single link AP MLD case: First ADD, link ID 0 would
be assigned and MLD interface wlan0 would be created. When REMOVE is
issued, the BSS would be deleted but MLD wlan0 will not. When ADD is
issued again, the BSS will tie back to MLD wlan0 but this time the link
ID will be incremented again and 1 would be assigned. Hence, at
subsequent REMOVE/ADD, the link ID keeps on incrementing.

Since the link ID remains same for the full lifetime of the BSS and MLD,
the next link ID counter cannot be just reset back to 0 when a BSS is
deleted. Otherwise, in interleaved link enable/disable case, the link ID
would be changed.

To overcome this situation, whenever a BSS is deleted, if the MLD is not
referenced by any other existing BSS, delete the MLD structure itself.

To know how many BSSs are referring a given MLD, introduce a new member
refcount in MLD. If the value is 0 it is safe to delete the MLD.

fac34688ad AP MLD: Assign link ID during BSS creation
Link ID was assigned when BSS is going through setup and the driver
interface init. Later if interface is disabled and enabled again, setup
BSS is called which will give a new link ID to it. However, Link ID
should be same for a BSS affliated to an AP MLD for the full lifetime of
the BSS.

Hence, assign the link ID during BSS creation itself. And it will remain
until BSS entry is completely freed. Hence, link ID will not change as
part of disable/enable.

Also, since link ID would be decided now, it will help in creating link
level control sockets in a subsequent patch.

MLD level information like MLD MAC address, next link ID, etc. was

these members and the other link BSSs store references to the first BSS.
However, if the first BSS is disabled, the first BSS reference in all
BSS should be updated which is an overhead. Also, this does not seem to
scale.

Instead, a separate MLD level structure can be maintained which can
store all this ML related information. All affiliated link BSSs can keep
reference to this MLD structure.

This commit adds that MLD level structure. However, assigning values to
it and using that instead of BSS level members will be done in

259b43a31a hostapd: MLO: Avoid use of mld_id as user configuration
mld_id was provided as a user configuration to identify partner BSS
belonging to the same AP MLD. The same id is used at the protocol level
also to indicate the AP MLD ID of the MLD.

But, in general mld_id is a relative reference of the MLD where 0 is
used as the mld_id to represent the self MLD and in case of MLO MBSSID
mld_id of a non transmitted BSS affiliated to an AP MLD is based on the
relative BSS index of the non transmitted BSS from the transmitted BSS.
Hence mld_id need not be fetched from users, rather it can be identified
wherever required.

To verify if the partners belong to the same AP MLD the interface name
can be checked, since all link BSS partners of the same AP MLD belong to
the same interface.

Hence, remove use of mld_id user config and instead introduce two
functions hostapd_is_ml_partner() and hostapd_get_mld_id(). The former
is used to verify whether partners belong to the same AP MLD and the
latter is used to get the MLD ID of the BSS.

b653420a23 AP MLD: Set link address only when non-AP MLD is not added to driver
Once the non-AP MLD is added to the driver, the driver handles the
address translation so that hostapd receives Management frames with
SA/DA being translated into MLD MAC addresses.

If the Authentication frmae is retransmitted with transaction being 1,
SA of the retransmitted Authentication frame is translated into the MLD
MAC address by the driver, and then in the function handle_auth(),
sta->mld_info.links[].peer_addr would be replaced by the MLD MAC address
even though it is supposed to be the link address.

Therefore, update the MLD information only when the STA has not yet been
added into the driver to avoid replacing the previously determined link
address with the MLD MAC address.

8fa52a7974 FT: Allow wpa_supplicant to be configured to prepend PMKR1Name
The standard is somewhat unclear on whether the PMKIDs used in
(Re)Association Request frame (i.e., potential PMKIDs that could be used
for PMKSA caching during the initial mobility domain association) are to
be retained or removed when generating EAPOL-Key msg 2/4.

wpa_supplicant has replaced the PMKID List contents from (Re)Association
Request frame with PMKR1Name when generating EAPOL-Key msg 2/4 for FT.
Allow it to be configured (ft_prepend_pmkid=1) to prepend the PMKR1Name

(Re)Association Request frame (i.e., potential PMKIDs that could be used
for PMKSA caching during the initial mobility domain association) are to
be retained or removed when generating EAPOL-Key msg 2/4.

hostapd used to require that only the PMKR1Name is included in the PMKID
List of RSNE in EAPOL-Key msg 2/4. Extend this to allow the PMKIDs that
were included in the (Re)Association Request frame to be present as long
as the correct PMKR1Name is also present. This would allow PMKSA caching
to be used in initial mobility domain association with supplicant
implementations that insert the PMKR1Name without removing the PMKIDs
used in the (Re)Association Request frame. wpa_supplicant did not use to
that, but other implementations might.

5603899976 AP MLD: Handle EAPOL only on the association link
For some implementation, there is no link id in EAPOL event, e.g., use
drv_event_eapol_rx for receiving. Current design for such case is switch
to a link that stores the peer. However, this is error-prone because for
non-AP MLD case, sta_info is stored in all valid links but EAPOL sm is
only initialized in the association link. If EAPOL RX event is handled
in a non-association link, it will be discarded and this leads to EAPOL
timeout.

So find the association link to handle received EAPOL frame in such
case. This replaces the previously used workaround for RSN/wpa_sm for
the no link id specified case.

392114a179 FT: Add dynamic reload of RxKH definitions from file
hostapd reads the list of Rx Key Holders from hostapd.conf file.
However, for systems where topology changes dynamically, the update
of RxKHs list is required without reloading the whole configuration.

Introduce a new source of RxKH definition with original syntax:
- rxkh_file - Path to a file containing a list of RxKHs.

In addition, add a control interface command RELOAD_RXKHS to
reload RxKHs definition from the file specified in `rxkh_file`.

This allows hostapd to properly distribute Rx keys even after topology
change (assuming rxkh_file is updated and reload_rxkhs command issued).

Syntax of rxkh_file is the same as extraction of r0kh and r1kh options
from original hostapd.conf file.

```
r0kh=ff:ff:ff:ff:ff:ff * 00112233445566778899aabbccddeeff

5589d62c57 nl80211: Avoid NL80211_WPA_VERSION_3 on older kernel versions
NL80211_WPA_VERSION_3 was only added in kernel 5.2 so it should not be
set for older kernel versions.  There is no direct way to check if the
value is supported. However, we can use the new infrastructure to check
whether the kernel has the NL80211_ATTR_SAE_PASSWORD attribute. It is
related and was added at the same time.

Extend RSN authenticator to be able to process EAPOL-Key msg 2/4 and 4/4
messages in cases where the Key Data field is encrypted using AES key
wrapping (i.e., non-AEAD cipher). While there is not yet any defined
case where such encryption would be used in IEEE Std 802.11-2020,
extensions are considered to be added to use such constructions (e.g.,
in IEEE P802.11bh). As such, it is good to extend the parsing and

f7a903654f Extend mechanism to distinguish EAPOL-Key msg 2/4 from 4/4
The initial Authenticator implementation depended on the Key Data field
being empty for EAPOL-Key msg 4/4. This worked fine for years in
practice, but in theory, vendor specific elements or KDEs could have
been added inti EAPOL-Key msg 4/4 and that would have broken this
design. In addition, the MLD case did introduce a KDE into EAPOL-Key msg
4/4 and required changes here.

As an initial step to make this more robust for future extensions,
recognize a received EAPOL-Key message as msg 4/4 if it is for RSN
(i.e., not WPAv1), has Secure=1, contains an unencrypted Key Data field,
and does not include RSNE.

'p2p->cfg->is_p2p_in_progress(p2p->cfg->cb_ctx)' will be true, too, so

cfg80211 requires the link ID to be specified for requests to start a

98f3bd26de ACS: Extend the 320 MHz support
There are bandwidth 320 MHz-1 and 320 MHz-2 channelization in EHT mode.
When using ACS, user might prefer one of the channelization or both, but
original ACS was unable to take such preference.

Another problem is that the original ACS returns only the ideal channel
but no 320 MHz channelization. The function acs_get_bw_center_chan()
also could not correctly return the center frequency of bandwidth 320
MHz that is decided by ACS.

For example, if ACS decide the ideal channel is channel 37 with
channelization 320 MHz-2 (center frequency 6265 MHz),
acs_get_bw_center_chan() returns 6105 MHz, which is 320 MHz-1.

Extend the support for 320 MHz so that ACS can choose the best channel
according to the user's preference. Also, after calling
acs_find_ideal_chan_mode(), the best channel and bandwidth can be
derived.

The changes are:
- bw_type ACS_BW320 is divided into ACS_BW320_1 and ACS_BW320_2
- in bandwidth 320 MHz, find the best channel and bandwidth according to
  user's perference (320 MHz-1, 320 Mhz-2 or both are OK)
- before acs_find_ideal_chan_mode() returns, update bw320_offset in
  iface->conf so that the best channel's channelization is recorded.
- get the best center frequency from bw320_offset
