Hi misc@,
I'm running 5.5-current from May 12 build (dmesg attached).
I noticed a regression in bwi(4) network device driver. I knew it
worked fine somewhere between 5.4-current built on January and
5.5-release, unfortunately I haven't enough informations to narrow the
timeframe.
BTW, here are the issues.
Network with bwi has become *slow*, slow as unusable. Every kind of
traffic is somehow slowed. Transmissions work but they take forever to
complete.
WIFI network is wpa encrypted; when using dhclient things seem to get
worse.
I enabled debugging on bwi0 and console got flooded with:
bwi0: received probe_resp from my:ap:lladdress rssi 54 mode 11g
bwi0: received probe_resp from my:ap:lladdress rssi 54 mode 11g
bwi0: received probe_resp from my:ap:lladdress rssi 55 mode 11g
bwi0: received probe_resp from not:my:ap:lladdress rssi 36 mode 11g
bwi0: received probe_resp from another:ap:but:not:mine rssi 34 mode 11g
bwi0: received probe_resp from yet:another:ap rssi 35 mode 11g
bwi0: received probe_resp from another:ap:but:not:mine rssi 35 mode 11g

[...]
My network card seems too busy managing beacons to actually route
IP packets.
After some minutes of "activity" (as trying to browse www.openbsd.org)
netsta -W bwi0 outputs the following:
ieee80211 on bwi0:
0 input packets with bad version
0 input packets too short
0 input packets from wrong bssid
1154 input packet duplicates discarded
0 input packets with wrong direction
10 input multicast echo packets discarded
0 input packets from unassociated station discarded
1 input encrypted packet without wep/wpa config discarded
0 input unencrypted packets with wep/wpa config discarded
39 input wep/wpa packets processing failed
0 input packet decapsulations failed
0 input management packets discarded
0 input control packets discarded
0 input packets with truncated rate set
0 input packets with missing elements
0 input packets with elements too big
0 input packets with elements too small
0 input packets with invalid channel
66 input packets with mismatched channel
0 node allocations failed
0 input packets with mismatched ssid
0 input packets with unsupported auth algorithm
0 input authentications failed
0 input associations from wrong bssid
0 input associations without authentication
0 input associations with mismatched capabilities
0 input associations without matching rates
0 input associations with bad rsn ie
1 input deauthentication packet
0 input disassociation packets
0 input packets with unknown subtype
0 input packets failed for lack of mbufs
0 input decryptions failed on crc
0 input ahdemo management packets discarded
0 input packets with bad auth request
17 input eapol-key packets
0 input eapol-key packets with bad mic
0 input eapol-key packets replayed
0 input packets with bad tkip mic
0 input tkip mic failure notifications
0 input packets on unauthenticated port
0 output packets failed for lack of mbufs
0 output packets failed for no nodes
0 output packets of unknown management type
1 output packet on unauthenticated port
2 active scans started
0 passive scans started
0 nodes timed out
0 failures with no memory for crypto ctx
0 ccmp decryption errors
0 ccmp replayed frames
0 cmac icv errors
0 cmac replayed frames
10 tkip icv errors
10 tkip replays
So I plugged in a spare ral-based USB dongle, enabled debug and looked
at console output:
it performed the active scan, then it associated to my ap...
...and nothing more than group rekeying. Action beacons sometimes.
netstat -W looks normal.
Suggestions to further debug this? bwi used to work well, unfortunately
I can't really say when this problem arose.
Thanks,
f.
