I do see one of these (which, I'd assume, is actually expected if you
have something on the system that runs to transmit before 4-way
handshake is completed).
I also have seen one of these for some time.
wlan0: dropped frame to c0:3f:0e:be:2b:44 (unauthorized port)
wlan0: dropped frame to c0:3f:0e:be:2b:44 (unauthorized port)
But this does not show up in my tests with mac80211_hwsim and the
current wireless-testing.git and hostap.git snapshots.
The regression was bisected to commit
df881293c6ba9a12868491a717b25cb14ec1fa4a.
Did you confirm that the latest snapshot works with this reverted?
With the commit reverted, the latest kernel-wireless version works.
If you need any more debugging output for this problem, please let me
know.
Since I was unable to reproduce, some more debug output could be
useful. Please at least verify that the STA entry for the AP is not
marked authorized. The next step would be to check whether sta_set_flags
in wpa_supplicant driver_nl80211.c is failing. Unfortunately, it looks
like the current implementation does not make this very clear in the
debug log, so some additional prints may be needed there.
Just to be clear, b43 is used as a station, not as AP. The card I am using has a
G PHY. I added printk statements for every setting of 'authorized' in
net/mac80211/tx.c. It is set false at line 1984, thus 'multicast' is false.
Furthermore, sta is not NULL, but WLAN_STA_AUTHORIZED is not set in the sta
flags. Note: sta->_flags is 0x60023.
Although sdata->vif.type is set to 2 (NL80211_IFTYPE_STATION), variable
'authorized' was not touched at line 1908, thus "sdata->wdev.wiphy->flags &
WIPHY_FLAG_SUPPORTS_TDLS" is false. The content of sdata->wdev.wiphy->flags is
0x1401f8.
Please also describe the security configuration (WPA2-Personal/CCMP?)
that you are using.
I'm running openSUSE 12.3 RC1, which has version 1.1 of wpa_supplicant. The
router is a Netgear WNDR3300 running standard firmware and set for WPA2-PSK(AES)
encryption.
Checking with newer versions of the supplicant is being a problem. I built both
2.0 from the tarball and 2.1-devel from the git repo, but nether will run with
NetworkManager. I will see if I can resolve that problem later.
Thanks,
Larry
