Hiya,

So the beacon miss / TSFOOR is the driver side. I can go take another look at
fixing that up.

The CCMP replay attack thing - that we need another NIC to sniff the air in
monitor mode and try to capture the invalid PN showing up in the air. If it's
coming over the air then sure, we can nail it down. If it's not coming over the
air, and instead it's corrupted by the AR9380 NIC, we're in trouble.

I need to go double / triple-check to see if we pass frames that fail
CRC/FCS/decrypt up to the stack for incorrect processing. I'm kinda worried
that we're processing invalid frames a little too far along the input /
decryption path.



Ummm... I am not familiar with this device,  but I have run into similar 
issues on other IO devices.  Do you have a spare/replacement device you 
can substitute in?   It turned out that on one system one of the device 
chip registers was magically 'losing' a bit.  We did not discover the 
cause of this problem until after much pain and effort  and we replaced 
the motherboard.  After that experience,  I always try a replacement 
device first.   Also,  if is software related then the replacement will 
continue to show the problem.  If it is hardware then you will get NO 
problems, or if Murphy's Law is active, DIFFERENT problems.


Good luck, Adrian,  you have solved some REALLY weird problems before.

Hello.

I haven't seen those replays before, only yesterday, due to the messages file
it happened at 15:48 and 21:59. That's it.

But I already have -bgscan disabled in rc.conf and powersave mode seems to be
turned off:

$ ifconfig -v wlan0 | grep -i power 
AES-CCM 3:128-bit powersavemode OFF powersavesleep 100 txpower 20

$ grep wlan /etc/rc.conf
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP mtu 1480 channel 9 -bgscan ssid KPECT"

So no way to solve the problem? Maybe reinstalling the router nearer to the
station?

Yeah, that's a beacon miss. I'm not sure why that is yet.

You can try -bgscan -powersave just to enforce things, but I don't know if it's
going to help all that much. The PN corruption is just very damned frightening.
I've seen it before but it's been really tricky to nail down :(

God damnit, okay. So it /looks/ like a single bit corruption of the RSC, which
causes the AES-CCM code to consider everything afterwards to be a replay
attack.

ie:

Adrians-MacBook-Pro:~ adrian$ perl -e 'printf "%x\n", 3407656;'
33ff28
Adrians-MacBook-Pro:~ adrian$ perl -e 'printf "%x\n", 2150891303;'
8033ff27

Those are from your AES-CCM replay logs.

I would've thought that a single bit error would've been caught by the MAC
CRC/FCS.

hi,

can you capture the whole dmesg from association to disconnects? I'd like to
see what's going on the whole time.

Thanks!

Hi Adrian.

Below is what I got. Up till TSFOOR line in dmesg is what came out when the

Hi Adrian.
Now there's nothing more than this:

wlan0: Ethernet address: f8:1a:67:09:d2:7b
wlan0: link state changed to UP
wlan0: link state changed to DOWN
wlan0: link state changed to UP
ifa_maintain_loopback_route: deletion failed for interface wlan0: 3
wlan0: link state changed to DOWN
wlan0: Ethernet address: f8:1a:67:09:d2:7b
wlan0: link state changed to UP
wlan0: link state changed to DOWN
wlan0: link state changed to UP

I'll try to recompile the kernel with options you've provided and will post it
as soon as I have the required info.

Thanx,
Sergey.

hi

what's logged in dmesg?

Can you compile with ATH_DEBUG, AH_DEBUG, ATH_DIAGAPI, and IEEE80211_DEBUG ?
There's likely some debugging we can turn on to figure out why traffic is
hanging. (My guess it's encryption - but let's first compile in with the
above.)

THen when its' done, do this:

wlandebug +assoc +state +auth +crypto

and then capture what's logged in dmesg when it stops working.

Bug ID: 213621
   Summary: WIFI connection is lost periodically on ath0
   Product: Base System
   Version: 11.0-STABLE
  Hardware: amd64
OS: Any
Status: New
  Severity: Affects Some People
  Priority: ---
 Component: wireless
  Assignee: freebsd-wireless@FreeBSD.org
  Reporter: kp...@protonmail.com

Hello.

Every several hours my wifi connection is lost. Removing tunnings from
sysctl.conf, tuning different setings on wifi router (disabling MAC Filtering,
chnging Beacon Interval/DTIM Interval/DHCP Address Lease Time/Group Key Update
Period) didn't help.
When connection is lost ifconfig shows nothing special, status stays
'associated'.

pinging shows following:
$ ping 192.168.0.1  
PING 192.168.0.1 (192.168.0.1): 56 data bytes

When I do 'reassociate' command inside wpa_cli shell connection restores. Also
it restores by running /etc/rc.d/netif restart.
Below is the listing from truss'ing wpa_supplicant service (first comes lines
when connection is lost, then I did reassociate):
