Package: src:linux
Version: 4.15.4-1
Severity: normal
Dear Maintainer,
starting with 4.14.17-1 and also seen on 4.15.4-1, my USB Wifi adapter remains
connected to my WPA2/CCMP access point but, after some time, minutes to hours,
all IP traffic stops (or at least I see no responses). IP traffic remains
stopped until the ath9k_htc module is unloaded and reloaded or the adapter is
unplugged and replugged. Operation can be restored with "modprobe -r ath9k_htc;
modprobe ath9k_htc".
This failure was not seen on 4.14.13-1.
Configuration:
- TP-Link TL-WN722N adapter
- Atheros AR9271 chipset
- USB ID: 0cf3:9271
- Module: ath9k_htc
- firmware-atheros (20170823-1) (firmware ath9k_htc/htc_9271-1.4.0.fw)
When IP traffic stops, no web pages load, "dig google.com" fails, and I cannot
ping any WLAN hosts including the router:
$ ping -c 1 router
PING router (192.168.1.254) 56(84) bytes of data.
From ripley (192.168.1.1) icmp_seq=1 Destination Host Unreachable
--- router ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms
When IP traffic is stopped, "route" output is normal.
The adapter is still responding:
- NetworkManager applet shows connection with full details
- "iw dev wlan0 link" shows still connected and byte and packet counters keep
increasing
- "iw dev wlan0 station dump" shows byte and packet counters that keep
increasing
# iw dev wlan0 link

MFP: no

(I am using net.ifnames=0 hence wlan0.)
Investigation:
- Testing a different modem of the exact same model does not fix so it is
unlikely to be a hardware failure
- ath9k_htc nohwcrypt=1 does not fix
- Switching to firmware-ath9k-htc (1.4.0-97-g75b3e59+dfsg-1) (firmware
ath9k_htc/htc_9271-1.dev.0.fw) does not fix
- NetworkManager debug logging had no output at the time of the hang: dbus-send
--system --print-reply --dest=org.freedesktop.NetworkManager
/org/freedesktop/NetworkManager org.freedesktop.NetworkManager.SetLogging
string:"debug" string:""
- Dropping iptables has no effect.
- linux-image-4.14.0-3-amd64 (4.14.13-1) not affected (or at least not yet
seen)
- linux-image-4.14.0-3-amd64 (4.14.17-1) AFFECTED
- linux-image-4.15.0-1-amd64 (4.15.4-1) AFFECTED
- pti=off has no effect
I have downgraded to 4.14.13-1, but booted into an affected kernel for the
purpose of this report. I needed to reload the ath9k_htc module twice while
submitting this report!
Kind regards,
Ben.

Version: 4.15.4-1
Severity: normal
Dear Maintainer,
starting with 4.14.17-1 and also seen on 4.15.4-1, my USB Wifi adapter remains
connected to my WPA2/CCMP access point but, after some time, minutes to hours,
all IP traffic stops (or at least I see no responses). IP traffic remains
stopped until the ath9k_htc module is unloaded and reloaded or the adapter is
unplugged and replugged. Operation can be restored with "modprobe -r ath9k_htc;
modprobe ath9k_htc".
This failure was not seen on 4.14.13-1.
Configuration:
- TP-Link TL-WN722N adapter
- Atheros AR9271 chipset
- USB ID: 0cf3:9271
- Module: ath9k_htc
- firmware-atheros (20170823-1) (firmware ath9k_htc/htc_9271-1.4.0.fw)
When IP traffic stops, no web pages load, "dig google.com" fails, and I cannot
ping any WLAN hosts including the router:
$ ping -c 1 router
PING router (192.168.1.254) 56(84) bytes of data.

When IP traffic is stopped, "route" output is normal.
The adapter is still responding:
- NetworkManager applet shows connection with full details
- "iw dev wlan0 link" shows still connected and byte and packet counters keep
increasing
- "iw dev wlan0 station dump" shows byte and packet counters that keep
increasing

- Switching to firmware-ath9k-htc (1.4.0-97-g75b3e59+dfsg-1) (firmware
ath9k_htc/htc_9271-1.dev.0.fw) does not fix
- NetworkManager debug logging had no output at the time of the hang: dbus-send
--system --print-reply --dest=org.freedesktop.NetworkManager
/org/freedesktop/NetworkManager org.freedesktop.NetworkManager.SetLogging
string:"debug" string:""
- Dropping iptables has no effect.
- linux-image-4.14.0-3-amd64 (4.14.13-1) not affected (or at least not yet
seen)
- linux-image-4.14.0-3-amd64 (4.14.17-1) AFFECTED
- linux-image-4.15.0-1-amd64 (4.15.4-1) AFFECTED
- pti=off has no effect
I have downgraded to 4.14.13-1, but booted into an affected kernel for the
purpose of this report. I needed to reload the ath9k_htc module twice while
submitting this report!
Kind regards,
Ben.

I have identified he problematic commit as
7b6ddeaf27eca72795ceeae2f0f347db1b5f9a30 ("mac80211: use QoS NDP for AP
probing") on torvalds/master and linux-stable/linux-4.15.y. On
linux-stable/linux-4.14.y: e23090a7d8f05f03cf564148472130286f5ca9bf.
Attached patch reverts this commit. I have submitted the patch upstream.
It applies (with a little fuzz) against Debian 4.15.4-1.
From the patch:
The above commit causes an Atheros AR9271 ath9k_htc USB WiFi adapter
connected to an AP with QoS/WME enabled to lose all IP connectivity after
something like 10 to 90 minutes. The adapter remains up and associated
and "iw dev wlan0 station dump" shows byte and packet counters that keep
increasing, but all IP connectivity fails, including ping, DNS, and web.
The host cannot be pinged by other hosts on the WLAN. Network can be
restored by unloading and reloading the ath9k_htc module, or physically
unplugging and replugging the adapter, triggering NetworkManager to
reconnect.
[...]
Problem confirmed on Debian linux-image-4.14.0-3-amd64 4.14.17-1 and
Debian linux-image-4.15.0-1-amd64 4.15.4-1 and vanilla 4.14.16
(git e23090a7d8f0 from linux-stable/linux-4.14.y) and vanilla 4.16.0-rc2
(git 3664ce2d9309 from torvalds/master).
Fix tested by reverting the commit on vanilla 4.16.0-rc2 (git 3664ce2d9309
from torvalds/master) and applying the patch to Debian
linux-image-4.15.0-1-amd64 4.15.4-1. Both tests resulted in stable IP
connectivity.

patch, made against torvalds/master, and also a backport for v4.15.4
from linux-stable that can be used to rebuild linux-image-4.15.0-1-amd64

to 4.15.x source which lacks TDLS_BUFFER_STA change; please use the
backport version ("...-backport.patch) of the mac80211 patch, also
attached, for 4.15.x, where it applies cleanly.
mac80211: add ieee80211_hw flag for QoS NDP support
Also requires a new one-line patch from the module maintainer to turn on
the new flag:
ath9k_htc: use non-QoS NDP for AP probing
https://patchwork.kernel.org/patch/10299031/
Patches attached. Note that the mac80211 patch for master will not apply
to 4.15.x source which lacks TDLS_BUFFER_STA change; please use the
backport version ("...-backport.patch) of the mac80211 patch, also
attached, for 4.15.x, where it applies cleanly.
