[B.A.T.M.A.N.] [hostapd] [batman-adv] Is dot11RSNAConfigPMKLifetime the correct setting to configure IBSS reauth timer?

Hi community,

We have batman-adv mesh network of 136 nodes perfectly running for about 6 months.

Our configure is: - OpenWRT tag 15.05.1 - wpa_supplicant hostap_2_4 - 802.11 IBSS - proto=WPA2 - key_mgmt=WPA-PSK - pairwise=CCMP - group=CCMP

The minor issue we have is that memory is fragmented after running 6 months for a large network of 136 nodes. I am speculating that it is because of the periodical RNSA  reauthentication.

If I read 802.11 spec "11.5.10 RSNA authentication in an IBSS" correctly, there is reauth timer.  Is dot11RSNAConfigPMKLifetime in wpa_supplicant.conf the setting for the reauthentication timer?

The default value is 43200 (12 hours). What about I change this value to be 2 weeks or a year?

Thanks. Xuebing Wang
