Hello everyone,
i'm running Kubuntu 16.04 as a Virtualbox VM host, and a wireless AP

My WLAN connections frequently keep dying, so that i need to disconnect

My syslog is full of these:

Also added to wireless-info.txt for better legibility.
I'm not sure if this is the right forum to post this.
If it isn't, a pointer to the right place would be appreciated.
Please include me in the reply as i'm not on the list.
Let me know, what additional details i need to provide, as i'm
interested in getting this to work.
Thanks.
Regards
Mario

This is a right place. Another right place is Ubuntu bug reporting.

There's a good chance this problem has been fixed already. You
are using a v4.4 kernel with many patches applied by Ubuntu. Here, we
are more concerned with the latest kernels, and v4.4 is quite old.
Please test some of the later kernels, see
https://wiki.ubuntu.com/Kernel/MainlineBuilds
In particular, test v4.13 or v4.14-rc4.
If the problem still happens, capture the same information and send it
again as a reply.
If the problem doesn't happen, then you can either continue to use the
new kernel, or find when the problem was fixed; a long but rewarding
process.
Should the problem have been fixed for v4.10, you might also switch to
using the Ubuntu package linux-generic-hwe-16.04.
https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack#hwe-16.04
Hope that helps.

I'm having a hard time with that, because the virtualbox-dkms build
fails with the 4.13 kernel, and virtualbox unfortunately is essential.

Is virtualbox essential for reproducing the problem, or essential for
your general use?
If the former, then that's interesting.
If the latter, then you might instead test the v4.13 or v14-rc4
kernels for only the problem, and then revert to an older kernel after
testing.
Either way, to use virtualbox-dkms with a later kernel you may be able
to upgrade just the virtualbox packages from a later Ubuntu release.
See https://packages.ubuntu.com/virtualbox-dkms and
https://packages.ubuntu.com/virtualbox for the later versions available.
Purpose of the test can be to help isolate the cause, not only to
solve your problem.

You might also try with later firmware package.
See https://packages.ubuntu.com/linux-firmware
You might also test with booting installation media in live-mode,
ignoring the internal disk.

It is essential for general use, like Internet connectivity.

Ok, that was completely off the radar.
I ended up going the other way. I still had a 4.4.0-79-generic kernel
and booted that. It does not have this problem.
After checking out
git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial
i tried to find the culprit but was not able to trace the back trace to
a potential null pointer or some such. I got stuck at
iwl_mvm_send_cmd_pdu_status not finding a reference to
iwl_mvm_disable_txq from there.
I did got the following diff though
git diff Ubuntu-4.4.0-79.100 Ubuntu-4.4.0-93.116 --
drivers/net/wireless/iwlwifi/ drivers/net/wireless/mac80211_hwsim.c >
wifi.patch
I don't know whether this came from upstream or was ubuntu sourced.
This fixed the issue for now, but now i'm stuck on that kernel :(
While i'm perfectly comfortable with user land C, i have no kernel
experience (clue stick links definitely welcome).

Okay, good, that means we can ignore virtualbox, and leave that to
you.
Please test v4.13 or v4.14-rc5, ignoring virtualbox for the time being.

Updating linux-firmware may run different firmware on the wireless
card, and the change in behaviour may fix the problem. A gamble.
A test with later installation media is useful, because you can verify
problems with different kernels and wireless firmware without change
to configuration. You might try Ubuntu 17.10 Artful ISO.

Upstream.
You found your problem was introduced in an Ubuntu kernel, in the
update from -79 to -93. This contained Ubuntu backports of two
stable kernel patches, which are also upstream patches;
8fbcfeb8a9cc ("mac80211_hwsim: Replace bogus hrtimer clockid")
from v4.4.69
50ea05efaf3b ("mac80211: pass block ack session timeout to to driver")
from v4.4.77
git log Ubuntu-4.4.0-79.100..Ubuntu-4.4.0-93.116 -- \
drivers/net/wireless/iwlwifi/ drivers/net/wireless/mac80211_hwsim.c
git remote add stable \
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
git fetch stable
git log v4.4.68..v4.4.92 -- \
drivers/net/wireless/iwlwifi/ drivers/net/wireless/mac80211_hwsim.c
> This fixed the issue for now, but now i'm stuck on that kernel :(
Yes.
Here in upstream, we would run the latest kernel v4.13 and work to
fix that. Trouble you had with virtualbox packages would be
eventually solvable, but aren't really a problem with the kernel
itself.
So your next step may be to report an Ubuntu bug, and say that -79
worked fine, and -93 did not.

You might verify the above patches caused the problem by doing a
bisection between -79 and -93.
https://wiki.ubuntu.com/Kernel/KernelBisection
Or by reverting only those patches.
Then report to Ubuntu which patch caused the problem.

Hope that helps.

Sorry for skipping the list one the last one.

As the 4.4.0-79 kernel was sometimes crapping out, too, i decided to try
to test the latest kernel instead of bisecting after all.
This took a while because virtualbox was being a bitch. virtualbox-5.0
doesn't bode well with virtualbox-dkms-51, so i ended up rebuilding
virtualbox-5.1 to prevent dependency hell.
The vb-dkms package doesn't do 4.14, so i ended up going with the 4.13
kernel that comes with artful.
This one pretty quickly loads my syslog with new error stacks. I haven't
tested actual behavior yet, but the logs don't look so hot.
I ran another wireless-info (attached) and appended some of the syslog
stuff to it.

I have gotten around to that part, yet, as i was busy with the above,
but it seems later versions have issues, too.

You didn't say virtualbox was essential for reproducing the problem,
so I'm continuing to exclude it from thought. If it is essential for
reproducing, then you might contact them.
Please do make sure you can exclude virtualbox as a cause.

Thanks, you identified a line of code and cause; a WARN_ON in
iwl_mvm_rx_tx_cmd_single;
case TX_STATUS_FAIL_DEST_PS:
/* In DQA, the FW should have stopped the queue and not
* return this status
*/
WARN_ON(iwl_mvm_is_dqa_supported(mvm));
info->flags |= IEEE80211_TX_STAT_TX_FILTERED;
break;
But it is only a warning. If connections aren't dying, it may not be
important to you.
Please check you are using the most recent linux-firmware?

However, you're still testing old source code.
Several changes made since are worth testing, please either
cherry-pick the patches or test a 4.14 rc kernel, and without
involving dkms or virtualbox.
Or, if new firmware fixes the problem, go with that instead.

Let me clarify the virtualbox thing. The machine in question is a VM
host. It hosts several machines, one of which is my mail server, and
another (openbsd) which acts as a gateway to the internet for all machines.
If i run this machine without virtualbox, then my entire network
topology is off-line. While one could argue, that this is bad design,
the alternative would be to use openbsd as a virtual host, but i haven't
seen many tutorials on that. I also would like to run just one machine
24/7 to keep a tap on the electricity consumption.
This machine also bridges several interfaces and acts as a hotspot for
my wlan.
So i don't know whether virtualbox is responsible, but not running
virtualbox is simply not an option.

I'm running
ii linux-firmware 1.169 all
from artful.
No difference to the xenial version.

Then i'd have to patch those files so they build for 4.14 first.
I've seen patches, but still need to figure out how to get them applied
in the build process.

Thanks.
I don't have a machine with the same wireless device, so I can't hope
to reproduce the problem or test fixes. I do have a slightly later
wireless device which uses the same driver, but I'm not confident it
would reproduce the problem, because (a) I've not seen the same stack
traces, (b) the WARN_ON relates to device response coded in firmware,
and my wireless device may use different firmware, and (c) it isn't
clear to me what you did to enable the problem.
You do have a machine, and you might do tests without virtualbox,
but as you say, this is not an option for you.

It may be more efficient to wait for your dkms packagers to catch up
so that the v4.14-rc6 or v4.14 kernel will work with your
package configuration.

Regarding whether wifi hangs, it's usually takes a while to get going
and then disappears. Sunday night i ended up rebooting into the 4.4-79
kernel because the 4.13 just got too ridiculous.
I.e. Wlan off, wlan on no longer worked.

Just in case i haven't answered that it's at 1.169

I just managed to patch the 5.1.30 dkms package so i wouldn't need to
update to virtualbox-5.2.
Here are the results with the 4.14-rc7 kernel.
As last time i appended what fills my syslog now.
