Do we support management frame protection? I'm using iwlwifi on -current. Work now requires it so I can't connect anymore. I did some testing with OpenWRT at home and when I require 802.11w Management Frame Protection then I can't connect. Linux works fine. Linux shows pmf=2 for wpa_supplicant and when I set that doesn't help for FreeBSD. I'm using wpa_supplicant from ports which is the same version running on Linux. With pmf=2 set in wpa_supplicant.conf in the debug output I see: wlan0: skip RSN IE - no mgmt frame protection enabled but AP requires it wlan0: reject due to mismatch with WPA/WPA2 without I see: bsd_set_key: alg=3 addr=0x23f788 key_idx=1 set_tx=0 seq_len=6 key_len=16 wlan0: WPA: IGTK keyid 4 pn 000000000000 WPA: IGTK - hexdump(len=16): [REMOVED] bsd_set_key: alg=4 addr=0x23f788 key_idx=4 set_tx=0 seq_len=6 key_len=16 ioctl[SIOCS80211, op=19, val=0, arg_len=64]: Invalid argument wlan0: WPA: Failed to configure IGTK to the driver wlan0: RSN: Failed to configure IGTK and then it disconnects. 802.11r Fast Transition in OpenWRT seems to work okay when I enable that without PMF. Thanks, Doug A.help
