[PATCH] wifi: brcmsmac: advertise MFP_CAPABLE to enable WPA3

[Arend van Spriel]

[-- Attachment #1: Type: text/plain, Size: 1146 bytes --]

After being asked about support for WPA3 for BCM43224 chipset it
was found that all it takes is setting the MFP_CAPABLE flag and
mac80211 will take care of all that is needed [1].

Testing this on a Raspberry Pi 4 [1] against a UniFi U6Pro AP I can't
connect to my WPA3 only SSID, it works fine with the SSID that's
WPA2/WPA3 on the same AP. It doesn't connect and I get a whole lot of
the following errors while it tries:

[  155.988865] brcmfmac: brcmf_set_channel: set chanspec 0xd02e fail, reason -52
[  156.100906] brcmfmac: brcmf_set_channel: set chanspec 0xd034 fail, reason -52
[  156.108597] brcmfmac: brcmf_set_channel: set chanspec 0xd038 fail, reason -52
[  156.116317] brcmfmac: brcmf_set_channel: set chanspec 0xd03c fail, reason -52

I also have a RPi3 (BCM43430/1) and a Rock960 (BCM4356/2) with working
brcmfmac WiFi I can test if that's useful.

The Raspberry Pis' WiFi chipsets use the brcmfmac driver and this is a
patch to the brcmsmac driver. This driver is for older and simpler
WiFi chipsets than the ones on the Raspberry Pis.

The devil is in the details ;-) Good that you tested. Maybe we can look 
into the WPA3-only problem. Are you using wpa_supplicant? Can you share 
supplicant log file and kernel log with brcmfmac debug modparam set to 0x1416.

Regards,
Arend

The RPis and the brcmfmac cards.
The current RPiOS for 32 bit and 64 bit OS have firmware which loads
on the 5Ghz capable Pis (3b+, 4, 5, 02W) which advertise WPA3
capability (this is a Pi5, but others are similar) This firmware is
from 2021:

I am pretty sure I am fully up to date.

I set up hostapd running an WPA3 SAE config on my desktop with an
intel card and can connect to it from my phone.
I cannot connect to it from the Pi5:
I tried using a config file and connecting with wpa_supplicant and it did not:
# cat /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

Successfully initialized wpa_supplicant

I tried using wpa_cli as well and it also fails:

Would love it if there were a way to get wpa3 to work with the
brcmfmac cards on RPI.

That looks sane to me.

The supplicant remains running in the foreground so that is normal. Could 
you retry with -ddt on the command line. Also having brcmfmac loaded with 
debug=0x1416 while testing. Finally, can you share the hostapd.conf file?

How do I load the debug parameter?

the other stuff you asked is here:

The hostapd on the desktop:
$ cat /etc/hostapd/hostapd.conf
# interface and driver
interface=ap0
driver=nl80211

# WIFI-Config
ssid=deskSAE
channel=1
hw_mode=g

wpa=2
wpa_key_mgmt=SAE
wpa_pairwise=CCMP
sae_password=secret123
sae_groups=19
ieee80211w=2
sae_pwe=0

The response

I suspect the message above indicates the problem as there is no 
available key_mgmt to select so looked it up in the code and here it is:

         sel = ie.key_mgmt & ssid->key_mgmt;
#ifdef CONFIG_SAE
         if ((!(wpa_s->drv_flags & WPA_DRIVER_FLAGS_SAE) &&
              !(wpa_s->drv_flags2 & WPA_DRIVER_FLAGS2_SAE_OFFLOAD_STA)) ||
             wpas_is_sae_avoided(wpa_s, ssid, &ie))
                 sel &= ~(WPA_KEY_MGMT_SAE | WPA_KEY_MGMT_SAE_EXT_KEY |
                          WPA_KEY_MGMT_FT_SAE | 
WPA_KEY_MGMT_FT_SAE_EXT_KEY);
#endif /* CONFIG_SAE */
#ifdef CONFIG_IEEE80211R
         if (!(wpa_s->drv_flags & (WPA_DRIVER_FLAGS_SME |
                                   WPA_DRIVER_FLAGS_UPDATE_FT_IES)))
                 sel &= ~WPA_KEY_MGMT_FT;
#endif /* CONFIG_IEEE80211R */
         wpa_dbg(wpa_s, MSG_DEBUG,
                 "WPA: AP key_mgmt 0x%x network profile key_mgmt 0x%x; 
available key_mgmt 0x%x",
                 ie.key_mgmt, ssid->key_mgmt, sel);

So 0x400 matches the expectation:

#define WPA_KEY_MGMT_SAE BIT(10)

You already confirmed that the driver reports SAE and SAE offload 
support. So it seems wpas_is_sae_avoided() must return true. That will 
check whether the AP and network profile are setup to MFP. This seems to 
be the fact as your hostapd.conf and wpa_supplicant.conf both have 
ieee80211w=2 defined. This function can only return true when 
sae_check_mfp is enabled in configuration file:

# sae_check_mfp: Require PMF support to select SAE key_mgmt
# 0 = Do not check PMF for SAE (default)
# 1 = Limit SAE when PMF is not enabled
#
# When enabled SAE will not be selected if PMF will not be used
# for the connection.
# Scenarios where this check will limit SAE:
#  1) ieee80211w=0 is set for the network
#  2) The AP does not have PMF enabled.
#  3) ieee80211w is unset, pmf=1 is enabled globally, and
#     the device does not support the BIP cipher.
# Consider the configuration of global parameterss sae_check_mfp=1, 
pmf=1 and a
# network configured with ieee80211w unset and key_mgmt=SAE WPA-PSK.
# In the example WPA-PSK will be used if the device does not support
# the BIP cipher or the AP has PMF disabled.
# Limiting SAE with this check can avoid failing to associate to an AP
# that is configured with sae_requires_mfp=1 if the device does
# not support PMF due to lack of the BIP cipher.

The default is not to check it and you wpa_supplicant.conf does not 
specify it.

# cat /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev
update_config=1
network={
  ssid="deskSAE"
  sae_password="secret123"
  proto=RSN
  key_mgmt=SAE
  pairwise=CCMP
  ieee80211w=2
}

Arend,

I find the wpa_supplicant docs really hard to understand. I have read
through your response a few times and am still a bit confused. Does
this have to do with a pure wpa3 versus a wpa2/3 AP?

I have tried editing my hostapd.conf and my wpa_supplicant.conf and
still cannot get a connection, so I must be doing something wrong.
I commented the ieee80211w line on both and it would not connect.
I tried changing the wpa_key_mgmt on both ends to be 'SAE WPA_PSK' and
it still would not connect.

What *should* the configurations be in the hostapd.conf and
wpa_supplicant.conf to negotiate this as a pure wpa3 setup? What
should it be to be a wpa2/3 setup? My phone worked fine to connect
with the original hostapd setup, but I have no idea what it is doing.

Regards,

Keith

Correct. If I am not mistaken MFP aka PMF aka 802.11w is mandatory for WPA3.

As I mentioned in my previous email both config files listed above look 
okay to me (might be wrong though). The problem seems to be with 
wpas_is_sae_avoided(). For it to return true the config should have:

sae_check_mfp=1

But you don't have that and default is 0 so it should check for MFP. This 
is where my trail ends. To learn more I would add additional debug prints. 
Are you comfortable rebuilding wpa_supplicant from source?

Arend

Arend,

Thanks for the reply. I could try to rebuild wpa_supplicant from
source. This is on RPi, so debian *.debs which are a pain, but I think
I can do it.

Do I understand correctly that 'sae_check_mfp=1' is supposed to be in
the hostapd.conf and wpa_supplicant.conf? I can try that and see if
anything changes.

Why would I have to re-build wpa_supplicant?

Ok. We can try first to put following in wpa_supplicant.conf:

sae_check_mfp=0

Let me know if that makes any difference.

I would provide a patch with additional debug prints so I get better 
understanding what is going wrong. Would be great if you can apply that and 
rebuild.

Arend

Arend,

I was able to try it this afternoon.
My hostapd is still:
# interface and driver
interface=ap0
driver=nl80211

# WIFI-Config
ssid=deskSAE
channel=1
hw_mode=g

wpa=2
wpa_key_mgmt=SAE
wpa_pairwise=CCMP
sae_password=secret123
sae_groups=19
ieee80211w=2
sae_pwe=0

and I can still connect from my phone to this AP.

I tried this as my /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev
update_config=1
 network={
  ssid="deskSAE"
  sae_password="secret123"
  proto=RSN
  key_mgmt=SAE
  pairwise=CCMP
  ieee80211w=2
  sae_check_mfp=1
}

and when I try to connect, I get:
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
Successfully initialized wpa_supplicant
Line 10: unknown network field 'sae_check_mfp'.
Line 11: failed to parse network block.
Failed to read or parse configuration
'/etc/wpa_supplicant/wpa_supplicant-wlan0.conf'.
: CTRL-EVENT-DSCP-POLICY clear_all

my version of wpa_supplicant is
# wpa_supplicant -v
wpa_supplicant v2.10

I will build the latest from git and await your patch.

Right. The setting sae_check_mfp is a global setting like update_config. So 
it should be moved outside the network block.

Arend,

Thanks for the hand holding, I am out of my depth here!

I tried this config and get a similar result.
ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev
update_config=1
sae_check_mfp=1
 network={
  ssid="deskSAE"
  sae_password="secret123"
  proto=RSN
  key_mgmt=SAE
  pairwise=CCMP
  ieee80211w=2
}
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
Successfully initialized wpa_supplicant
Line 3: unknown global field 'sae_check_mfp=1'.
Line 3: Invalid configuration line 'sae_check_mfp=1'.
Failed to read or parse configuration
'/etc/wpa_supplicant/wpa_supplicant-wlan0.conf'.
: CTRL-EVENT-DSCP-POLICY clear_all

seems it doesn't recognize this parameter.

Replying to my own post.
I re-built wpa_supplicant from the current git:
# wpa_supplicant -v
wpa_supplicant v2.11-devel-hostap_2_10-2215-gc9db4925f
Copyright (c) 2003-2022, Jouni Malinen <j@w1.fi> and contributors

It now seems to recognize the 'sae_check_mfp' parameter, but still
does not connect:
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
Successfully initialized wpa_supplicant

I tried setting the 'sae_check_mfp' to both 1 and 0 and still cannot
connect with this 'current' version of wpa_supplicant.

Arend,

I ran across this note today and investigated it with the
wpa_supplicant I am now using:
https://github.com/raspberrypi/linux/pull/5945

It still will not connect with this firmware

Take that and reverse it...
I was having a conflict and figured out that:
wpa_supplicant.service was running and failed to connect as it did not
have the proper config for teh SSID in question.

Once I stopped the service and tried to connect via cli, I was able to
get it to do so and was able to verify the connection worked:

# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

so, it appears that SAE does work, but you need to have a newer
cyfmac.bin file than what is shipped on the RPis.
This is what is reported, currently:

I do get a ton of this in the log, though:

I suspect this is the same issue that Stefan Wahren reported a while 
ago. That thread dried up which is probably my bad. That chanspec 0xd022 
is encoded channel info translating to "band=5G bw=20MHz channel=34". As 
far as I know channel 34 is an old Japan channel. Not sure if it is 
valid today. So we can remove them probably. However, these messages are 
also reported on some channels that are valid in certain regions. Need 
to discuss with Johannes what the best option is. Will revive the 
original email thread [1].

Arend

Hi Keith,

maybe you are missing sae_pwe=2 in your wpa_supplicant.conf
At least in our setup it works.

Arend,

Yes, I figured it out. As per the link shared: I had to put the latest
firmware on and use the latest wpa_supplicant, but with these 2
changes, it did connect.

I think I get what it is supposed to do, but am unsure of how to do it.

the modules referred to in that link (b43 or ieee80211) do not appear
to be loaded:
# lsmod | grep 802
8021q                  49152  0
garp                   49152  1 8021q
nf_conntrack          180224  1 nf_nat
cfg80211             1032192  1 brcmfmac
rfkill                 49152  7 bluetooth,cfg80211

How do I set this up to work on RPiOS?

Keith

Sorry, but I think we have hijacked this thread so changing the subject.

@Kalle:
Hope you are not too confused. My comment on my own patch was about adding 
a Tested-by: tag which I forgot to include.

Sorry for the confusion but the above is about brcmsmac, which is a

modules. I will respond the email you sent before this one.
