Hi folks,
Myself and several others are hitting a issue with the latest
wpa_supplicant version (2.7). wpa_supplicant has added support for
4-way handshake offload for 802.1X. With this new version,
wpa_supplicant fails to associate and hits a kernel warning which
appears related to how the driver or firmware advertises 4-way
handshake offload support.
There is an Arch Linux bug open on this with a bunch of details here:
https://bugs.archlinux.org/task/61119
The wpa_supplicant folks note that this appears to be a driver issue
and suggested I report the problem here. Reverting to wpa_supplicant
2.6 without 4-way handshake offload support works around the problem.
Here is the kernel warning:

Hi Eric,
Not sure what the root cause is yet, but the warning means wpa_s is
issuing a NL80211_CMD_SET_PMK, but it did not pass the
NL80211_ATTR_WANT_1X_4WAY_HS flag attribute in the NL80211_CMD_CONNECT.
So at first glance it looks like user-space does not adhere to the api
description:
/**
* DOC: WPA/WPA2 EAPOL handshake offload
*
* By setting @NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag drivers
* can indicate they support offloading EAPOL handshakes for WPA/WPA2
* preshared key authentication. In %NL80211_CMD_CONNECT the preshared
* key should be specified using %NL80211_ATTR_PMK. Drivers supporting
* this offload may reject the %NL80211_CMD_CONNECT when no preshared
* key material is provided, for example when that driver does not
* support setting the temporal keys through %CMD_NEW_KEY.
*
* Similarly @NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_1X flag can be
* set by drivers indicating offload support of the PTK/GTK EAPOL
* handshakes during 802.1X authentication. In order to use the offload
* the %NL80211_CMD_CONNECT should have %NL80211_ATTR_WANT_1X_4WAY_HS
* attribute flag. Drivers supporting this offload may reject the
* %NL80211_CMD_CONNECT when the attribute flag is not present.
*
* For 802.1X the PMK or PMK-R0 are set by providing %NL80211_ATTR_PMK
* using %NL80211_CMD_SET_PMK. For offloaded FT support also
* %NL80211_ATTR_PMKR0_NAME must be provided.
*/
However, better make sure there is nothing wrong in the driver. Could
you apply the patch below and let me know what the warning looks like.
Regards,
Arend

The ArchLinux issue seems to be using broadcom-wl driver, while you have
issue with brcmfmac. Just to clarify I can only support the brcmfmac driver.

Looking at the original log in the ArchLinux issue, it is completely
something else so I ignore that for now and focus on your issue.

Thanks, Arend. I applied the patch that you sent and the resulting
warning shows "use_fwsup=0". Does this mean I should follow up with
wpa_supplicant?
I noticed that with WPA2, I can associate fine and everything works as
expected, but it fails with this warning with WPA2-Enterprise w/ PEAP
& MSCHAPv2.
