Re: [PATCH] wifi: brcmfmac: cfg80211: Handle SSID based pmksa deletion

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:

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
