Hi
WPA3 is broken on T2 Macs (atleast on 4364) for a long time. I was under
the impression brcmfmac doesn't support it.
Anyways, I've asked a fedora user to compile a kernel with CONFIG_BRCMDBG.
If you want logs without it, look over here:

Not sure what to make of this. The interface comes up without any obvious
error and then another interface is created by another driver:
[ 7.006441] rtl8xxxu 1-8.3:1.0 wlp0s20f0u8u3: renamed from wlan0
That interface connects:
[ 9.103599] wlp0s20f0u8u3: authenticate with 98:da:c4:af:1f:c2 (local
address=2e:87:9a:a9:38:66)
[ 9.103605] wlp0s20f0u8u3: send auth to 98:da:c4:af:1f:c2 (try 1/3)
[ 9.109051] wlp0s20f0u8u3: authenticated
[ 9.110202] wlp0s20f0u8u3: associate with 98:da:c4:af:1f:c2 (try 1/3)
[ 9.126945] wlp0s20f0u8u3: RX AssocResp from 98:da:c4:af:1f:c2
(capab=0x1431 status=0 aid=5)
[ 9.127678] usb 1-8.3: rtl8xxxu_bss_info_changed: HT supported
[ 9.128606] wlp0s20f0u8u3: associated
Is brcmfmac setup to connect to the same access point. There are a lot of
unknowns here.

Arend

Hi
wpa_supplicant 2.11 broke Wi-Fi on T2 Macs as well, but this patch
doesn't seem to be fixing Wi-Fi. Instead, it's breaking it even on
older 2.10 wpa_supplicant. Tested by a user on bcm4364b2 wifi chip with
a WPA2-PSK [AES] network. dmesg output:
On bcm4377, bcm4378 and bcm4388 (chipsets used in M1/M2 macs)
WPA3-SAE and WPA2-PSK still works with Fedora's wpa_supplicant 2.10.
Fedora's package carried SAE offload patches in 2.10.
wpa_supplicant 2.11 still doesn't work with this patch but it prevents a
kernel oops after a disconnect (due to an authentication timeout in the
current broken state) in wpa_supplicant.
I'll continue to debug the wpa_supplicant 2.11
best regards,
Janne
