Re: WiFi fails to connect after wpa_supplicant update

@loqs yes unpatched wpa_supplicant 2.10 works for me.
git bisecting yield:

41638606054a09867fe3f9a2b5523aa4678cbfa5 is the first bad commit
commit 41638606054a09867fe3f9a2b5523aa4678cbfa5 (HEAD)
Author: Vinayak Yadawad <vinayak.yadawad@broadcom.com>
Date:   Thu Jun 30 09:37:53 2022 +0530

    Mark authorization completed on driver indication during 4-way HS offload

    In case of drivers supporting 4-way handshake offload, mark port
    authorized and state completion only if the driver advertizes authorized
    state in the connect event. Otherwise there are fair chances of the
    driver port authorization API getting called while 4-way handshake is in
    progress at the lower layer.

    In order to avoid this possible race condition always update port
    authorization and supplicant state WPA_COMPLETED setting from
    EVENT_PORT_AUTHORIZED context when the driver is done with the 4-way
    handshake.

Re: WiFi fails to connect after wpa_supplicant update

Thank you for performing the bisection and locating the upstream reports.  Do you need help testing the proposed kernel fix wifi: brcmfmac: cfg80211: Handle SSID based pmksa deletion?

Re: WiFi fails to connect after wpa_supplicant update

@loqs I applied the patch to linux 6.10.3-arch1-2, and checked the "src/linux-6.10.3/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c" and the patch applied succefully, but wpa_supplicant 2:2.11-2 still time-out trying to authenticate.

Re: WiFi fails to connect after wpa_supplicant update

Does Disabling offloading in brcmfmac with "brcmfmac.feature_disable=0x82000" allow wpa_supplicant 2:2.11-2 to work correctly?

Re: WiFi fails to connect after wpa_supplicant update

yes booting linux 6.10.3.arch1-2 with kernel option brcmfmac.feature_disable=0x82000
allow wpa_supplicant 2:2.11-2 to work.

Re: WiFi fails to connect after wpa_supplicant update

Can you try incrementing the pkgrel of the linux PKGBUILD by .1 then build and install that package and then check `modinfo brcmfmac` that the filename and vermagic fields report the incremented version?

Re: WiFi fails to connect after wpa_supplicant update

Adding brcmfmac.feature_disable=0x82000 does workaround the issue for me as well.

This seems like a better workaround than holding back wpa_supplicant, but let me know if it isn't.

Re: WiFi fails to connect after wpa_supplicant update

wifi-brcmfmac-cfg80211-handle-ssid-based-pmksa-deletion.patch is queued for 6.10.7.  If that still has the issue you will need to report that back upstream.

Re: WiFi fails to connect after wpa_supplicant update

I removed the kernel parameter after updating to 6.10.7 and Wi-Fi is working fine on my 2012 MacBook Pro, so seems like it's resolved.

Re: WiFi fails to connect after wpa_supplicant update

I upgraded kernel to 6.10.7 and wpa_supplicant to 2.11-2, but after reboot I got the same error. I had to downgrade wpa_supplicant to get WiFi working again on my mid-2015 MacBook Pro.

Re: WiFi fails to connect after wpa_supplicant update

Are you using the brcmfmac module?

uname -a
lsmod | grep brcmfmac

Does "brcmfmac.feature_disable=0x82000" allow you to avoid the problem?
