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: https://pastebin.com/fnhH30JA ________________________________________ From: Janne Grunau <j@xxxxxxxxxx> Sent: 04 August 2024 11:49 To: Aditya Garg; devnull+j.jannau.net@xxxxxxxxxx Cc: arend.vanspriel@xxxxxxxxxxxx; asahi@xxxxxxxxxxxxxxx; brcm80211-dev-list.pdl@xxxxxxxxxxxx; brcm80211@xxxxxxxxxxxxxxx; kvalo@xxxxxxxxxx; linus.walleij@xxxxxxxxxx; LKML; linux-wireless@xxxxxxxxxxxxxxx; Hector Martin; stable@xxxxxxxxxxxxxxx Subject: Re: [PATCH] wifi: brcmfmac: cfg80211: Handle SSID based pmksa deletion Hej, On Sun, Aug 4, 2024, at 05:10, Aditya Garg wrote: > Hi > > wpa_supplicant 2.11 broke Wi-Fi on T2 Macs as well, but this patch > doesn't seem to be fixing Wi-Fi.

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
