We are using CYW43455 and occasionally we are seeing following log

ieee80211 phy0: brcmf_cfg80211_del_pmksa: Cache entry not found causes disconnect

Right after this log there's a notification about disconnect event from wpa_supplicant.

Can you please explain what this log means and hot it is related with disconnect event?

Thanks,
Bogdan

Hello:

     I have a check with our release, we do not set the config to Y,   From code description it means " to get PMKSA or set PMKSA by external commands"  like

    } else if (os_strncmp(buf, "PMKSA_GET ", 10) == 0) {
        reply_len = wpas_ctrl_iface_pmksa_get(wpa_s, buf + 10,
                              reply, reply_size);
    } else if (os_strncmp(buf, "PMKSA_ADD ", 10) == 0) {
        if (wpas_ctrl_iface_pmksa_add(wpa_s, buf + 10) < 0)
            reply_len = -1;


.  Actually,  we recommend to use the releases for supplicant and hostapd from our fmac package officially.

Hello:

    I have a check with our supplicant release, we have a PMKSA-cache-for-8021X fix.

Are you using the supplicant from our fmac release ?

Hi @Zhengbao_Zhang ,

Please do not close - we applied the changes but we are still testing.

Hi @Zhengbao_Zhang ,

Would you recommend this option enabled or disabled in wpa supplicant configuration:

CONFIG_PMKSA_CACHE_EXTERNAL=y

How does it affect patches you provided ?

Thanks,
Bogdan
