[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Kamal Mostafa]

walterramjet, the 5 bug was indeed still present in your kernel
version (4.2.0-36.*).  For the 4.2.0 kernel series, it was fixed in
version 4.2.0-42.49 as noted in comment #59 here, so running a regular
system software update is probably what you need to do.

However, its confusing that you also mention that you're running Ubuntu
16.10 ("Yakkety") since Yakkety's kernel series is 4.8.0.  Perhaps
you're actually running Ubuntu 15.10 ("Wily") which used the 4.2.0
kernel series.  If so, note that Wily is now past its end-of-life and is
no longer supported.

Earlier posts say this bug was fixed in linux 4.4.0-30.49.  My system
has been fine since then.

[Geoffrey Ellison]

Thanks Viktor.
Following my post #65...
I've been running kernel 4.4.0-47-generic for a week now and the problem has 
not come up once.
So for my part, the kernel update has fixed it.

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Viktor Pal]

Greetings Geoffrey,

I'm running the latest Mint (18) and I did not see issues with my K520 keyboard 
so far.
I'm using the kernel that comes (I guess 4.4) with the release.
So I guess updating the kernel to the latest should definitely help.
The patch was released with 4.4.0-31.50 as I see.

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Geoffrey Ellison]

I'm experiencing this on a K350 keyboard, on 4.4.0-21-generic kernel
(fresh install of Linux Mint 18 Sarah / Ubuntu 16.04 LTS).

I usually see the problem after changing windows by clicking on one in
the panel. As the new window takes focus, the ...555's start
flying.

Another curious symptom: occasionally, pressing the number "5" key while
typing does not output anything. It just happened while I was typing
this sentence.

But after having read all the above posts, I am going to try a kernel
upgrade now. For some reason Mint has marked the kernel updates as
"unsafe" which why I'm still on the release kernel of 4.4.0-21-generic.

I will report my results.

I'm also experiencing this bug on a K350 keyboard on Ubuntu 16.10.  It's
been a problem on and off for a few years with this same keyboard
though.

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Kamal Mostafa]

This fix will appear in the next normal automatic kernel update for
15.10 (which currently scheduled for July 18 -- my previous estimate was
off by one week).

However, that kernel is available in the "-proposed" archive right now,
so if you don't want to wait for the normal update you can install it
early: see instructions in comment #45.

I have this issue with an MK710 on Ubuntu 15.10

Glad there is a fix.  Sorry I am not clear. Will this be in an automatic
update for 15.10 or should I manually update the kernel?

Tim: Correct, there is no need to also test 4.4.0-30.

Given that we've had no further reports of this problem, we'll now
consider it to be verified as fixed in the -proposed kernels.  Those
kernels are scheduled to be released via standard -updates within the
next week.

Thanks for posting the handy instructions, Tim.

It isn't really necessary for all previously affected users to post
"positive" results (since they will necessarily be inconclusive anyway).
As long as we get at least a couple of folks (including myself) to
report no further instance of the problem with the -proposed kernel by
mid-next-week, we'll call it resolved.

I will handle manipulating the bug status and all the "verified-done-
" tags at that time; users do not need to adjust them.

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Tim Passingham]

On xenial I found it easiest to:

- add the proposed repository via 'Software and Updates', in the
'Developer Options' tab, tick the 'pre-released updates' box

- using synaptic, reload the repos, mark all upgrades, and then tick
only the 4 'linux-..' kernel items to get version 4.4.0.29.


- I then updated just these

- I then went back to untick the 'pre-released updates' box so I don't
get any more test versions.


I assume testers need to post both positive and negative results here by Sunday 
3rd June - please confirm this.

Do us users change the status of this bug, or does Kamal?

Affected users: As noted above, the kernel versions available in the
-proposed include this fix now.  Since the problem can't be positively
verified, we'll consider the problem "verified" as long as we do not get
any reports to the contrary in the next few days.

So, if you install the -proposed kernel and yet still experience any
instance of the  problem, please post that here along with the
output of 'uname -a'.

The "out of the normal cycle" kernel versions released yesterday were

The "normal cycle" kernel versions that we're preparing this week _do_
include this fix.  A note will be posted here as soon as those kernels

I'm having the same issue. I'm on Xubuntu 16.04 and using logitech k800.
The only way to stop the issue is by logging out of the desktop. I'll be
trying the patched kernel today. I hope it works.

[Kamal Mostafa]

Darren, the fix is scheduled to be released in all affected Ubuntu
versions in the near future and a note will be posted here at that time.
In the meantime, the Xenial (amd64) test kernel indicated in Comment #16
should offer you some relief.

Thanks for the fix, where can I apply it now?  Ubuntu Xenial.  In 2
hours this bug has happened no less than 20 times.  Everything is
currently updated.

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Kamal Mostafa]

Tim, its essentially the same reason that we saw the problem manifest in
some Wily and Xenial kernel versions, then seem to disappear in the next
kernel version, only to return again in some future version:

The bug, which definitely existed all the way back through Precise, was
that the driver could access the wrong data (an out of bounds array
access) in some circumstances.  The theory is that for any each
individual kernel build, that particular wrong data it accesses might
end up containing 'the 5 key' (making this bug manifest) or might end up
containing a 'null' (resulting in no obvious manifestation for that
kernel build).  Its plausible that in Precise, the kernel builds just
always ended up with a 'null' there.

The fix patch ([mainline] 50220de HID: core: prevent out-of-bound
readings) prevents the driver from accessing that wrong data at all,
which is certainly the correct behavior whether or not the 5 problem
was seen to manifest.

Is there an obvious reason why users of trusty never had this problem

Summary of test kernel results: All users of the test kernel have
reported that it does appear to eliminate the 5 problem.

I will get the fix patch ([mainline] 50220de HID: core: prevent out-of-
bound readings) into the pipeline for all affected Ubuntu kernels, and a
note will be posted here once those kernels become available.

Thanks all, for the testing help!

[Tim Passingham]

As I said, "I was using the patched kernel, with no problems".  I was
away for a few days so have probably only run 4.4.0-22-generic
#40+lp1579190 for 4 or 5 days in all, so far without seeing the problem,
but it is transient.

4.4.0-24 didn't display the fault for a couple of days, and then did
today.

Hi Tim Passingham (tim-8aw3u04umo),

the new kernel you installed (4.4.0-24) will definitely produce the issue as it 
does not contain the patch.
Please clarify if you where also able to reproduce the issue with 
4.4.0-22-generic #40+lp1579190.

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Tim Passingham]

Sorry, I should have explained better.  I was using the patched kernel,
with no problems.  When the 24 update came up for installation a few
days ago I thought I would try it, so I did.  Today that newer version
still showed the same problem, so I have reverted to the patched version
(by using grub customizer to make it the default choice and checking
with uname).

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Viktor Pal]

Hi Tim Passingham (tim-8aw3u04umo),

you are not using the patched kernel.
The patched is: 4.4.0-22-generic #40+lp1579190
And you are using: 4.4.0-24

What might have happened is that you installed the patched kernel and then you 
updated Ubuntu and 4.4.0-24 was installed and set as the default kernel.
So after you restarted your machine your OS is not running the patched kernel 
any more.
To run the patched kernel you either have to modify the default kernel in the 
GRUB configuration or explicitly choose the patched kernel on startup.

BTW, I'm running 4.4.0-22-generic #40+lp1579190 since few days without any 
issues.
Any chance for this patch to get into the Ubuntu 16.04 repositories?

4.4.0-24-generic #43-Ubuntu SMP just failed for me as well.

I had installed it a few days ago and it was OK, but just went wild
again with repeating 5's.  It may be a coincidence, but I
also was using Thunderbird at the time.

I shall revert to the patched version.

I am still testing #40+lp1579190 and have not experienced 555's
yet but on an install of the new linux mint 18 Beta I have upped from
the default 4.4.0-21-generic to 4.4.0-24-generic #43-Ubuntu SMP and have
had no incidents of 555's in the 2 days I have had it installed.
Will continue testing the patch on U and 4.4.0-24 #43 on LM.

I mention this because 'maybe' a look into 4.4.0-24-generic #4 may be
worthwhile. ?

I have been running the patched kernel for a couple of days now. The
555's have totally ceased. I was experiencing the 5's frequently
daily prior to the patch but I realize the problem often vanishes for
periods of time. I will test for another week or so and also will inform
you promptly if I have a 555's event prior to then.

I have just installed the patched version. I had to remove both 4.6 and

patched version).

I'll report either way in a week or 2 (or sooner if the bug appears

4.4.0-22.40 plus:
[mainline] 50220de HID: core: prevent out-of-bound readings

The test kernel is here (most users will only need to 'dpkg -i' install

After installing, please verify that 'uname -a' shows this version number:

If you *still* experience the "" problem with this test kernel,
please post that here immediately!

If you do not experience the problem anymore, then please post that here
after a few days of testing time.  Thanks!

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Kamal Mostafa]

Doug, you added the tag 'kernel-fixed-upstream' but I don't think we
have hard evidence of that at this point.  Was your tagging based only
on Viktor's reports that it hasn't happened (yet) on a 4.6 kernel, or is
there more information elsewhere?

Viktor, your result with 4.6 is promising!  However, since this problem
is known to "come and go" it is also possible that code has just moved
around such that its just not manifesting in your current 4.6 kernel
build you currently (but could reappear in some future build of 4.6).

I do see one potentially interesting fix in 4.6 (50220de HID: core:
prevent out-of-bound reading).  I'm going to produce a test kernel with
just that fix backported on top of Xenial 4.4.0-22.40 (which I've seen
manifest the problem), and will post that here for further testing.

Still not able to reproduce this with 4.6 kernel series.
It is very likely that this issue is already fixed there.
Any chance this could be backported to the xenial kernel as this is an LTS 
release?

I also get this behaviour with my Logitech K520 keyboard and unifying
receiver, on Ubuntu 16.04 and on 15.10 before that.

The same bug has been reported on the RedHat bug tracker:
https://bugzilla.redhat.com/show_bug.cgi?id=1278818

According to that, the hid-logitech-hidpp driver might be the culprit.

I'm interested to hear that Viktor has not yet seen the problem with the
4.6 kernel. Viktor, please keep us posted when you've run it for a bit

[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards

[Gerhard Koegl]

I'm using a Logitech K20 wireless keyboard and it randomly repeats 
5.
After an event the fist key pressed (no matter which key) is not recognized.
It is pretty annoying especially when writing a text or  while programming.
Does not happen under Windows (same computer).

I'm using 4.6.0 rc6 since about a week and haven't experienced this issue since 
then.
I would treat this as an evidence though. Will be continuing testing with the 
4.6 kernel series.
Installed the kernel from here: 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc6-wily/

[Viktor Pal]

Yes I WladyX I get freezes, but IIRC this is always how it was on Linux since I 
use it. :)
Are the freezes happening to you at the same same time the 5 key is repeated?

Joseph Salisbury, yes I can try the latest upstream kernel.
Will let you know the results.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.6 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

I also get freezes/hangs, may be unrelated, do you get them too?
