[Kernel-packages] [Bug 1383184] Re: Atheros Qualcomm Killer N1525 Wireless-AC [168c:003e] is not supported

[chevrier]

Max - can you provide some details at which exact steps you took, what kernel 
you use, what you tried etc?
Adam's solution is definitely working.
As a matter of fact, I just tried a fresh 15.10 install and it's working fine.  
Just followed steps and is all fine.
I just don't understand why my other 15.10 install just won't work.  I did 
remove the dmsg-ath10k package.  really confused.
:-s
let us know max, so we can help properly. see above posts.
thanks

  CURRENT STATUS:

  Wily(15.10) could not work with and don't need Adam's dkms package 1.0
  or 1.1

  Wily(15.10) has already fixed the driver part, and the firmware part
  is in progress.

  For now, you guys could use 15.10(purge the ath10k-dkms if you tried
  installing it), and make a copy of
  https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-
  firmware.git/plain/ath10k/QCA6174 into /lib/firmware/ath10k/

  Distros before 15.10(lower than 4.2 kernel) please keep using the
  dkms(which will be relocated soon)

[Kernel-packages] [Bug 1511844] [NEW] System freezes occasionally

[Freek]

Public bug reported:

Occasionally my system freezes totally. When this happens, the screen
totally freezes, no mouse movements anymore. Switching to Console via
Ctrl-Alt-F1 or rebooting via Ctrl-Alt-Del does not work. I have waited
at least 30 min, but the system doesn't seem to recover.

Some days my system will run for many hours without any problem,  and on
other days I experience 2 or 3 freezes in an hour time. So far I have
not noticed any similarities between the moments of freezing in regard
to programs running etc.

I filled in this report after reading
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723 which
seemed to describe the same thing to me, on a same brand laptop. The
freezes happened both on Ubuntu 15.04 and 15.10

Re: [Kernel-packages] [Bug 1509556] Re: Kubuntu Wily upgrade screen glitch with 4.2 kernel

[Bryan Cebuliak]

Nope.  Same  graphics problem  exists for   me with 4.2.5-wily  kernel
[sans xorg.conf].  Any  good   kernel is  likely  to be  an  earlier one,
not  a  later one, as  the  regression is  yet unidentified.

[Kernel-packages] [Bug 1486670] Re: using ipsec, many connections result in no buffer space error

[Dan Streetman]

Short summary:

ipsec uses a struct dst_ops object per net-namespace (e.g. per
container), but does not correctly initialize each dst_ops object's
percpu counter.  This results in incorrect values for each net
namespace's dst_ops counter.

Full details:

ipsec uses xfrm objects, which contain dst objects, which are tracked
via the xfrm dst_ops struct in its percpu counter.  However, ipsec
creates a dst_ops object for every net namespace, not just the main net
namespace.  A dst_ops template is created, and its contents copied to
the dst_ops object for each new net namespace.  However, ipsec only
initializes the percpu counter in the dst_ops object once - for the
template.  The way percpu counters work is, the percpu counter object
has a main counter variable, and a pointer to the percpu counter
variables.  The percpu variables only go up to a small "batch" size (32
or so), at which point the percpu variable's count is moved to the main
counter variable.  However since multiple ipsec net namespaces are all
using different main counter variables but the same percpu counter
variables, the count from each percpu variable can be moved to a
different net namespace.  The result is, one net namespace (i.e.
container) may have its xfrm count decrease to below 0, while another
net namespace may have its xfrm count increase forever, and eventually
cause complete ipsec failure once the xfrm4_gc_thresh limit is exceeded.

Bug description:
  Reproduction info:

  set up two LXC containers (although this probably isn't specific to
  LXC containers), and inside each setup ipsec with something similar
  to:

  conn nodeN
  aggressive=yes 
  authby=secret 
  auto=start 
  closeaction=restart 
  dpdaction=restart 
  esp=aes256-aes256gmac-modp1024 
  ike=aes256-sha512-modp1024 
  keyexchange=ikev2 
  left=10.0.3.145 
  leftid=10.0.3.145 
  lifetime=12h 
  reauth=no 
  right=10.0.3.199 
  type=transport 

  
  then repeatedly open connections to the peer, e.g.:

  while true; do ping -c1 10.0.3.199 ; sleep 0.1 ; done

  eventually, the connections will fail with:

  connect: No buffer space available

  the reproduction can be sped up by reducing the xfrm4_gc_thresh, e.g.:

  echo 5 > /proc/sys/net/ipv4/xfrm4_gc_thresh

  
  Once the error occurs, no more connections can be made to the peer (all fail 
with no buffer space available), however after a long period (e.g. overnight) 
the buffers will be cleaned up and connections can be made again.

  this happens even on the latest net-next kernel.

Title:
   Some Sony Dualshock 4 controllers do not work in kernel 3.15+

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I'm testing in Ubuntu 15.10 with kernel 4.2.0-16.19 but this bug
  report actually applies to ALL kernels starting at 3.15 until the
  current 4.3rc7 and is not limited to Ubuntu.

  I have a brand new Sony DualShock 4 that seems to use a slightly
  different protocol than the hid-sony driver expects. I'm not sure why
  this controller is different. Maybe updated firmware from Sony or
  maybe because it has never been connected to a PS4. Whatever the case,
  the device descriptor size is different from what hid-sony expects and
  because of that it does not remap the descriptor table as required.
  This causes only the trackpad to function (the trackpad uses a
  different code path) and none of the other controls work. So basically
  the controller does not work at all.

  I have created a patch that fixes it. I have only tested the patch
  against kernel 4.2 and 4.3 but it's simple enough that it should be
  trivially portable to any 3.15+ kernel. The attached patch is based
  against the Ubuntu mainline-crack git v4.2 kernel.

  I posted to the LKML asking if the descriptor size check was even
  necessary but never got a response so I left it in.

[Kernel-packages] [Bug 1511855] [NEW] Some Sony Dualshock 4 controllers do not work in kernel 3.15+

[Chris Osgood]

Public bug reported:

I'm testing in Ubuntu 15.10 with kernel 4.2.0-16.19 but this bug report
actually applies to ALL kernels starting at 3.15 until the current
4.3rc7 and is not limited to Ubuntu.

I have a brand new Sony DualShock 4 that seems to use a slightly
different protocol than the hid-sony driver expects. I'm not sure why
this controller is different. Maybe updated firmware from Sony or maybe
because it has never been connected to a PS4. Whatever the case, the
device descriptor size is different from what hid-sony expects and
because of that it does not remap the descriptor table as required. This
causes only the trackpad to function (the trackpad uses a different code
path) and none of the other controls work. So basically the controller
does not work at all.

I have created a patch that fixes it. I have only tested the patch
against kernel 4.2 and 4.3 but it's simple enough that it should be
trivially portable to any 3.15+ kernel. The attached patch is based
against the Ubuntu mainline-crack git v4.2 kernel.

I posted to the LKML asking if the descriptor size check was even
necessary but never got a response so I left it in.

[Kernel-packages] [Bug 1509120] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From ru...@us.ibm.com 2015-10-30 22:58 EDT---
Ahhh.  (In reply to comment #42)
> Sorry about the idmapd misdirection based on my cursory read of the stack.
> Since they are mounting with sec=sys, idmappng should be disabled.
^^

I think this is the trigger we have been missing.  This change does not
appear to be in place for the kernel version the customer is running on
his NFS server.  But it does appear to be the default behavior for the
servers we have been trying to replicate with.  Because of this,
mounting sec=sys is causing our test servers to send back uid/gid
information instead of name mapping (so our client code doesn't need the
callout).   I will try to install a down-rev system as a server for
validation if someone else doesn't beat me to the punch first.

  Process accounting deadlock with idmapd callout when writing to NFSv4

Status in linux package in Ubuntu:

  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.

  ---uname output---
  Linux ppc001 3.19.0-30-generic #34~14.04.1-Ubuntu SMP Fri Oct 2 22:21:52
  UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

  ---Problem Details---

  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the
  trigger was turning on process accounting and writing to a file hosted
  via an NFSv4 mount.  During the testing, several vmcores were
  captured, and the fingerprint indicates a mutex deadlock situation
  with process accounting.   In the most recent vmcore, it appears that
  the scenario is something like the following:

  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

  Soft lockup with "block nbdX: Attempted send on closed socket" spam

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

  Attaching apport files from 2 hosts below.

[Kernel-packages] [Bug 1504445] Re: FocalTech touchpad stops working after suspend

[Thatoo]

Thanks to Harris Anggara (harrisanggara) and Daniel Drake (dsdrake)  here, 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490130 , I could solve my 
problem by adding this patch to the kernel : 
https://marc.info/?l=linux-input=144312209020616=2

now i'm using kernel 4.2 for Ubuntu 14.04  with the patch. i changed the
DMI_PRODUCT_NAME with K501LX (because that is my laptop model).

I tried directly with kernel 4.2 because before that, kernel 3.19 and so, they 
need a driver for my touchpad. I followed the instruction here to obtain the 
source of kernel 4.2 for Ubuntu 14.04, 
https://wiki.ubuntu.com/Kernel/Dev/KernelGitGuide
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git
then from inside the folder you've just downloaded (cd ubuntu-trusty)
git tag -l Ubuntu-*
to know what is available for ubuntu 14.04
and then
git checkout -f -b temp Ubuntu-lts-4.2.0-6.6_14.04.1.1

After, to build the kernel, I followed this explanation, 
https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
fakeroot debian/rules clean
fakeroot debian/rules binary-headers binary-generic
then
cd ..
ls *.deb
linux-cloud-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-headers-4.2.0-6_4.2.0-6.6~14.04.1.1_all.deb
linux-headers-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-image-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-image-extra-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb

I deleted this two files because I don't need them
linux-cloud-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
and finally,
sudo dpkg -i linux*4.2.0-6.6~14.04.1.1*.deb
sudo reboot

Now it works nicely. The touchpad works fine, without the need to
install any driver and I can suspend the activity of my computer and
resume without loosing the touchpad. I hope the patch will be integrated
soon and I won't loose my touchpad again with updates in the future.

Thank you everybody,
Take care, always smiling,

Title:
   FocalTech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Triaged

Bug description:
  I have an Asus V502LX the persian version of the Asus K501LX.

  I have Ubuntu 14.04 installed and the kernel 4.1.6 installed. I had to
  install the kernel 4.1.6 to have the touchpad recognised. Under kernel
  3.19.30, as I am running now to file in this bug, the touchpad is
  recognised as a simple mouse (no two fingers scrolling...) and the
  problem I am describing below is also present...

  I noticed one problem. The Focaltech touchpad is not working after
  suspending the computer.

  Here is what I could find about the touchpad in
  /proc/bus/input/devices

  I: Bus=0011 Vendor=0002 Product=0012 Version=
  N: Name="FocalTechPS/2 FocalTech FocalTech Touchpad"
  P: Phys=isa0060/serio1/input0
  S: Sysfs=/devices/platform/i8042/serio1/input/input5

  H: Handlers=mouse0 event4
  B: PROP=5
  B: EV=b
  B: KEY=e520 1 0 0 0 0
  B: ABS=2608003

  Before suspending the computer, I can deactivate and activate again
  the touchpad with the hotkey of my keyboard without problem. However,
  once the computer suspended, nothing work to re-activate the touchpad.

  I tried a solution given on internet but it doesn't work properly.

  I created a file here /etc/pm/sleep.d/trackpad
  sudo gedit /etc/pm/sleep.d/trackpad

  and add the following
  #!/bin/sh
  case "$1" in
  suspend|hibernate)
  modprobe -r psmouse;
  resume|thaw)
  modprobe psmouse;
  esac

  With this file, the computer refuse to suspend. The touchpad keep
  working so it does something but I can't make my computer sleeping...

  I am running Ubuntu 15.10 and my notebook freezes occasionally. I had
  the same issue with Ubuntu 15.04, but I thought that 15.10 might
  change it. I am running Ubuntu on an Acer Aspire ES1-311 (P1D5).

  I have no clue what causes this, my system just freezes and I can't do
  anything anymore. ctrl+alt+f1 doesn't work as well as alt+print+REISUB
  doesn't work either. It's just frozen. I have to power down manually.

  Last time I was programming only with a gnome-terminal and atom
  (editor) opened. I checked some log files but I couldn't find anything
  suspicious.

  Any ideas?

[Kernel-packages] [Bug 1509803] Re: Bluetooth Will not work

[Pilot6]

I remember that these IDs have been removed from kernels because it
appeared to be two devices with the same IDs.

For some of the devices adding PATCHRAM caused regressions for the whole
system, like hangs or lags.

I can't find that commit yet. If someone finds it, please tell me or
Marcel Holtmann.

This patch appeared again in bluetooth-next.

That's weird. It does not try to load the firmware at all. Are you sure
the module is installed correctly?

Please give output of

Jeremy,
Ref: your reply post# 93 to alligator.

For the 168:0042 (rev 30) have you tried using the link I've provided?
It leads to kvolo's github page where you can find the corresponding
firmware.

[Kernel-packages] [Bug 1510789] Re: [HP Spectre x360 - 13-4002dx] No sound card detected

[Christopher M. Penalver]

Nicolae Istratii, could you please test the latest upstream kernel
available from the very top line at the top of the page from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't 
boot into the OS) please make a comment in your report about this, and continue 
to test the next most recent kernel version until you can test to the issue. 
Once you've tested the upstream kernel, please comment on which kernel version 
specifically you tested. If this issue is fixed in the mainline kernel, please 
add the following tags by clicking on the yellow circle with a black pencil 
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[Kernel-packages] [Bug 1509854] Re: drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled

[Christopher M. Penalver]

cropr, the next step is to fully reverse commit bisect from kernel 4.2
to 4.3-rc7 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

  Elantech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  i have asus a455ld i5 5200u running kubuntu 15.04 with kernel 
4.0.8-040008-generic. 
  touchpad is recognized as elantech version 4. everything was fine until my 
notebook go to suspend and resume without touchpad working.
  I tried :
  modprobe -r psmouse
  modprobe psmouse

  it only work before suspend.
  execute those commands after resume from suspend is not working.

  the last thing i tried is this.

  when i use this command before suspend :

  insmod
  /lib/modules/4.0.8-040008-generic/kernel/drivers/input/mouse/psmouse.ko

  these appear in the dmesg:

  [  820.207105] psmouse serio1: elantech: assuming hardware version 4 (with 
firmware version 0x381f00)
  [  820.70] psmouse serio1: elantech: Synaptics capabilities query result

  but when i use the command after suspend, there is nothing any output
  in the dmesg.

  i tried all ubuntu varian and opensuse 13.2 live usb, the result is the same. 
  but in windows 10,  touchpad still active after suspend.

Title:
  Elantech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  i have asus a455ld i5 5200u running kubuntu 15.04 with kernel 
4.0.8-040008-generic. 
  touchpad is recognized as elantech version 4. everything was fine until my 
notebook go to suspend and resume without touchpad working.
  I tried :
  modprobe -r psmouse
  modprobe psmouse

  it only work before suspend.
  execute those commands after resume from suspend is not working.

  the last thing i tried is this.

  when i use this command before suspend :

  insmod
  /lib/modules/4.0.8-040008-generic/kernel/drivers/input/mouse/psmouse.ko

  these appear in the dmesg:

  [  820.207105] psmouse serio1: elantech: assuming hardware version 4 (with 
firmware version 0x381f00)
  [  820.70] psmouse serio1: elantech: Synaptics capabilities query result

  [  820.294698] input: ETPS/2 Elantech Touchpad as 
/devices/platform/i8042/serio1/input/input146

  but when i use the command after suspend, there is nothing any output
  in the dmesg.

  i tried all ubuntu varian and opensuse 13.2 live usb, the result is the same. 
  but in windows 10,  touchpad still active after suspend.

[Kernel-packages] [Bug 1504445] Re: FocalTech touchpad stops working after suspend

[Thatoo]

I forgot to say that to identify your laptop model you can run
sudo dmidecode | grep Product\ Name

you'll need to change 
DMI_MATCH(DMI_PRODUCT_NAME, "X455LAB"),
by
DMI_MATCH(DMI_PRODUCT_NAME, "X"),

X being your laptop model

Title:
   FocalTech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Triaged

Bug description:
  I have an Asus V502LX the persian version of the Asus K501LX.

  I have Ubuntu 14.04 installed and the kernel 4.1.6 installed. I had to
  install the kernel 4.1.6 to have the touchpad recognised. Under kernel
  3.19.30, as I am running now to file in this bug, the touchpad is
  recognised as a simple mouse (no two fingers scrolling...) and the
  problem I am describing below is also present...

  I noticed one problem. The Focaltech touchpad is not working after
  suspending the computer.

  Here is what I could find about the touchpad in
  /proc/bus/input/devices

  I: Bus=0011 Vendor=0002 Product=0012 Version=
  N: Name="FocalTechPS/2 FocalTech FocalTech Touchpad"
  P: Phys=isa0060/serio1/input0
  S: Sysfs=/devices/platform/i8042/serio1/input/input5
  U: Uniq=
  H: Handlers=mouse0 event4
  B: PROP=5
  B: EV=b
  B: KEY=e520 1 0 0 0 0
  B: ABS=2608003

  Before suspending the computer, I can deactivate and activate again
  the touchpad with the hotkey of my keyboard without problem. However,
  once the computer suspended, nothing work to re-activate the touchpad.

  I tried a solution given on internet but it doesn't work properly.

  I created a file here /etc/pm/sleep.d/trackpad
  sudo gedit /etc/pm/sleep.d/trackpad

  and add the following
  #!/bin/sh
  case "$1" in
  suspend|hibernate)
  modprobe -r psmouse;
  resume|thaw)
  modprobe psmouse;
  esac

  With this file, the computer refuse to suspend. The touchpad keep
  working so it does something but I can't make my computer sleeping...

  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :

  Note that timestamps from kern.log appears to be wrong, it looks like

Status in linux package in Ubuntu:

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

Title:
  Soft lockup with "block nbdX: Attempted send on closed socket" spam

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

  Attaching apport files from 2 hosts below.

  Kubuntu Wily upgrade screen glitch with  4.2 kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On  recent  update   from  15.04   to  15.10, the new  4.2  kernel  is  
associated   withgraphics  instability after  a  few  seconds of   GUI  use 
  with  mouse   and   keyboard making  the  GUI  unusable.  See  another  
person's  same  experience   with  intel   graphics   here:

  Downgrading  to the  last   15.04kernel   solves  my  issue.

Title:
   Some Sony Dualshock 4 controllers do not work in kernel 3.15+

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I'm testing in Ubuntu 15.10 with kernel 4.2.0-16.19 but this bug
  report actually applies to ALL kernels starting at 3.15 until the
  current 4.3rc7 and is not limited to Ubuntu.

  I have a brand new Sony DualShock 4 that seems to use a slightly
  different protocol than the hid-sony driver expects. I'm not sure why
  this controller is different. Maybe updated firmware from Sony or
  maybe because it has never been connected to a PS4. Whatever the case,
  the device descriptor size is different from what hid-sony expects and
  because of that it does not remap the descriptor table as required.
  This causes only the trackpad to function (the trackpad uses a
  different code path) and none of the other controls work. So basically
  the controller does not work at all.

  I have created a patch that fixes it. I have only tested the patch
  against kernel 4.2 and 4.3 but it's simple enough that it should be
  trivially portable to any 3.15+ kernel. The attached patch is based
  against the Ubuntu mainline-crack git v4.2 kernel.

  I posted to the LKML asking if the descriptor size check was even
  necessary but never got a response so I left it in.

[Kernel-packages] [Bug 1507994] Re: Broadwell vaapi video decode broken by i915_bpo migration

[Stephen Thirlwall]

The offending upstream commit appears to be:

http://kernel.ubuntu.com/git/virgin/linux.git/commit/?id=dc9fb09cae5b1355c1a9d8102e40b97b34332f31

I still need to test this with mpv, and there's been some new mainline &
intel-drm-nightly kernels released since by last attempt.

  Broadwell vaapi video decode broken by i915_bpo migration

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Vivid:
  Incomplete
Status in linux source package in Wily:
  Confirmed

Bug description:
  Since upgrading from linux-image-3.19.0-28-generic to linux-
  image-3.19.0-30-generic, vaapi-accelerated video playback on Kodi 15.2
  (and 15.1) is now all black.

  On-screen display items (eg. elapsed time) and audio still work, but
  the decoded video content is now all black. Disabling vaapi
  acceleration in the Kodi options restores the video playback.

  I have bisected the problem to this commit:
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-
  vivid.git/commit/?id=059c4a45e7a0233ab06b16f591a7877d11f6d79c

  The problem still happens in Ubuntu-3.19.0-31.36, as well as
  Ubuntu-4.0.0-1.2 and Ubuntu-4.2.0-16.19 from the ubuntu-wily repo.

  It appears that the above commit flicks the switch on many changes,
  and doesn't really shed too much light on what the actual problem
  might be.

  I've tried moving that commit earlier into the history in the hope
  that I might be able to find a 'good' point to bisect from, but had no
  luck. The furthest I was able to push it back was
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-
  vivid.git/commit/?id=59b6d9aaa4c379d84930598183cb4911a2713ff4, but the
  problem remained.

  v4l2 can crash computer with badly written userland code

Status in linux package in Ubuntu:
  Expired

Bug description:
  In my simple bit of code to grab a frame from a webcam based on the
  example code given here:

  https://gist.github.com/Circuitsoft/1126411

  I found a badly crafted version would crash the computer (dead except
  for flashing keyboard lights).

  Simply calling ioctl(cam, VIDIOC_STREAMON, ) twice without
  calling VIDIOC_STREAMOFF inbetween causes the crash. I realise this
  code is incompetent but it shouldn't require a hard reboot to recover
  from it. I guess this might be rather system specific however it
  seemed worth reporting.

   I can't recall the last time I managed to crash a linux box from
  userland...

[Kernel-packages] [Bug 1509556] Re: Kubuntu Wily upgrade screen glitch with 4.2 kernel

[Riskable]

I take it all back...  As I was working on my WebGL code just now it
crashed again.  I've attached my Xorg.2.log which clearly shows a
problem:

[  1329.968] (WW) Falling back to old probe method for vesa

What's up with that permissions error?  Also, why is it even getting
such an error so late after running just fine for hours?

[Kernel-packages] [Bug 1509556] Re: Kubuntu Wily upgrade screen glitch with 4.2 kernel

[Riskable]

I was experiencing regular crashes and graphical glitching with KDE
Plasma 5 after upgrading to 15.10 and after discovering this bug I
decided to upgrade my kernel to the latest -wily version
(http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/).  That
seems to have corrected the issue.  The glitching has gone away and no
crashes so far after about 20 minutes of use with intensive WebGL
utilization (which was what was causing the crashes previously).

[Sergio Gelato]

Frank: I think it's better to file a new bug about this. Do include the
actual log message. I'm looking at the source code for 3.13.0-66.108 and
the fix is still in place, so it can't be *exactly* the same problem as
before.

Bug description:
  I've seen this happen twice in the last 8 days on an NFS server
  running Ubuntu precise and kernels 3.2.0-65.98-generic (on the first
  occasion) and 3.2.0-67.101-generic (the second time), amd64. This
  never happened before in several months of operation; until 2014-07-01
  this server was running an older 3.2.0 kernel.

  When this error appears in the logs, the system stops answering NFS
  RPCs (e.g., "rpcinfo -u localhost nfs 3" hangs) and a reboot is
  necessary to restore NFS service. A more detailed stack trace follows.
  Looking at the source code (fs/nfsd/vfs.c:set_nfsv4_acl_one()) I see
  that the call posix_acl_xattr_size(pacl->a_count) is not preceded by a
  check that pacl != NULL. Could this be related to the following entry
  in the changelog for 3.2.0-65.98?

  Soft lockup with "block nbdX: Attempted send on closed socket" spam

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

  Attaching apport files from 2 hosts below.

[Kernel-packages] [Bug 1505564] Re: Soft lockup with "block nbdX: Attempted send on closed socket" spam

[Junien Fridrick]

apport information

** Description changed:

  Hi,
  
  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket
  
  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared
  
  trusty hosts with kernel version 3.19.0-30-generic.
  
  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.
  
  Attaching apport files from 2 hosts below.

[Kernel-packages] [Bug 1511735] [NEW] libnl: fail to bind() netlink sockets

[Nicolas Dichtel]

Public bug reported:

The following upstream patches are needed in order to avoid failures
when binding a netlink socket:

1f734a8f892a lib/socket: randomize the generated local port
http://git.infradead.org/users/tgr/libnl.git/commitdiff/1f734a8f892a

4dd5fdd0af2c lib/socket: retry generate local port in nl_connect on ADDRINUSE
http://git.infradead.org/users/tgr/libnl.git/commitdiff/4dd5fdd0af2c

027157898708 lib/socket: don't fail if no more local ports can be assigned in 
nl_socket_alloc
http://git.infradead.org/users/tgr/libnl.git/commitdiff/027157898708

0fd510b3673f lib/socket: use proper typed constant UINT32_MAX for uint32_t 
typed port
http://git.infradead.org/users/tgr/libnl.git/commitdiff/0fd510b3673f

Without these patches, an application which opens and closes regularly

[Frank]

Issue seems to be reintroduced.

Mounts in 3.13.0-66-generic fail again with the same error messages as reported 
in this issue.
In 3.13.0-62-generic everything seems well.

Bug description:
  I've seen this happen twice in the last 8 days on an NFS server
  running Ubuntu precise and kernels 3.2.0-65.98-generic (on the first
  occasion) and 3.2.0-67.101-generic (the second time), amd64. This
  never happened before in several months of operation; until 2014-07-01
  this server was running an older 3.2.0 kernel.

  When this error appears in the logs, the system stops answering NFS
  RPCs (e.g., "rpcinfo -u localhost nfs 3" hangs) and a reboot is
  necessary to restore NFS service. A more detailed stack trace follows.
  Looking at the source code (fs/nfsd/vfs.c:set_nfsv4_acl_one()) I see
  that the call posix_acl_xattr_size(pacl->a_count) is not preceded by a
  check that pacl != NULL. Could this be related to the following entry
  in the changelog for 3.2.0-65.98?

Title:
  Soft lockup with "block nbdX: Attempted send on closed socket" spam

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

  Attaching apport files from 2 hosts below.

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

[Kernel-packages] [Bug 1390223] Re: Apparmor related regression on access to unix sockets on a candidate 3.16 backport kernel

[Wolfgang]

Ah those "upstream" kernels weren't pure... Just tested manually compiled 
kernel master branch and tag 4.2, no issues. Copied over a packaged one: 
problem reappears.
It's not a container problem though. Running this on a host has the same effect:
# aa-exec -p $pick_your_favorite_profile -- socat 
UNIX:/var/spool/postfix/public/showq -
also gets an EPERM.
Also not 32/64 bit dependent, however we do have some containers where it 
always works, and some where it always fails, and that was their only obvious 
distinction, which now seems unrelated.

  Apparmor related regression on access to unix sockets on a candidate
  3.16 backport kernel

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Utopic:
  Confirmed
Status in linux source package in Vivid:
  Fix Committed

Bug description:
  I recently noticed a bunch of containers failing in a rather odd way
  when running postfix.

  The most visible example is when running mailq on an empty queue.
  Without apparmor (unconfined container) I see that the queue is empty,
  with apparmor, I get Permission denied.

  That's all running as root so the permission denied looks a tiny bit
  odd. Also, running the 3.13 kernel, I don't get any of that weirdness.

  My guess is that it has to do with the work that went into the 3.16
  kernel for socket mediation. In theory only systems that run the
  utopic apparmor (which I DO NOT) should be seeing that kind of
  behavior, but it looks like some code path isn't checking things
  properly :)

  Kernel is a slightly outdated version of the kernel from the kernel team PPA:
  Linux shell01 3.16.0-23-generic #31-Ubuntu SMP Thu Oct 23 20:13:35 UTC 2014 
x86_64 x86_64 x86_64 GNU/Linux

  If you think the latest build will improve this, I can test it, but
  seeing how this is a production server, I can't just flip kernels
  every 5 minutes (I'm running 3.16 to avoid a nasty btrfs bug on 3.13).

Title:
  Soft lockup with "block nbdX: Attempted send on closed socket" spam

Status in linux package in Ubuntu:

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

Title:
  Soft lockup with "block nbdX: Attempted send on closed socket" spam

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  Some of our nova compute hosts regularly freeze, sometimes for a few hours, 
with kern.log getting spammed with :
  block nbdX: Attempted send on closed socket

  and a few "CPU soft lockup" messages (see attached log). This clears up when 
the queue gets cleared, eg :
  block nbdX: queue cleared

  trusty hosts with kernel version 3.19.0-30-generic.

  Note that timestamps from kern.log appears to be wrong, it looks like
  the messages are being held, and then all delivered at once when the
  kernel unfreezes.

  Attaching apport files from 2 hosts below.

Recently upgraded to ubuntu 15.10 (Wily Werewolf)
After the upgrade everything seems normal, USB tethering is working when system

[Kernel-packages] [Bug 1509120] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From ru...@us.ibm.com 2015-10-30 15:09 EDT---
I was also not able to replicate this behavior in my initial internal 
lab-system test, so it is nice to see our results are consistent so far.  The 
customer's idmap.conf config looks to be fairly generic:

root@ppc001:~# cat /etc/idmapd.conf
[General]

#Verbosity = 5
Pipefs-Directory = /run/rpc_pipefs
Domain = localdomain

[Mapping]

Nobody-User = nobody
Nobody-Group = nogroup

I'll start digging a little deeper into site/config differences now that
we seem to have consistent results in a test environment.

Title:
  Process accounting deadlock with idmapd callout when writing to NFSv4
  mount

Status in linux package in Ubuntu:
  In Progress

Bug description:
  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.

  ---uname output---
  Linux ppc001 3.19.0-30-generic #34~14.04.1-Ubuntu SMP Fri Oct 2 22:21:52
  UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

  ---Problem Details---

  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the
  trigger was turning on process accounting and writing to a file hosted
  via an NFSv4 mount.  During the testing, several vmcores were
  captured, and the fingerprint indicates a mutex deadlock situation
  with process accounting.   In the most recent vmcore, it appears that
  the scenario is something like the following:

  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

Title:
  USB tethering does not work after system Suspend

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Recently upgraded to ubuntu 15.10 (Wily Werewolf)
  After the upgrade everything seems normal, USB tethering is working when 
system boots. After a while I put the system to suspended state. On awakening 
the system USB tethering does not work.

  After restarting the system it seems to work just fine and the process
  is repeated when I put the system to suspend again.

  Thanks.

[Kernel-packages] [Bug 1511855] [NEW] Some Sony Dualshock 4 controllers do not work in kernel 3.15+

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I'm testing in Ubuntu 15.10 with kernel 4.2.0-16.19 but this bug report
actually applies to ALL kernels starting at 3.15 until the current
4.3rc7 and is not limited to Ubuntu.

I have a brand new Sony DualShock 4 that seems to use a slightly
different protocol than the hid-sony driver expects. I'm not sure why
this controller is different. Maybe updated firmware from Sony or maybe
because it has never been connected to a PS4. Whatever the case, the
device descriptor size is different from what hid-sony expects and
because of that it does not remap the descriptor table as required. This
causes only the trackpad to function (the trackpad uses a different code
path) and none of the other controls work. So basically the controller
does not work at all.

I have created a patch that fixes it. I have only tested the patch
against kernel 4.2 and 4.3 but it's simple enough that it should be
trivially portable to any 3.15+ kernel. The attached patch is based
against the Ubuntu mainline-crack git v4.2 kernel.

I posted to the LKML asking if the descriptor size check was even
necessary but never got a response so I left it in.

[Kernel-packages] [Bug 1509120] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From ru...@us.ibm.com 2015-10-30 22:06 EDT---
Sorry about the idmapd misdirection based on my cursory read of the stack.  
Since they are mounting with sec=sys, idmappng should be disabled.  After 
diving a bit deeper into the code path, it appears to actually be the 
/sbin/request-key user-mode helper program that is being invoked here.   I'm 
still digging into site config differences to see if I can better understand 
why we are unable to replicate this behavior in our own testing.

Title:
  Process accounting deadlock with idmapd callout when writing to NFSv4
  mount

Status in linux package in Ubuntu:
  In Progress

Bug description:
  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.

  ---uname output---
  Linux ppc001 3.19.0-30-generic #34~14.04.1-Ubuntu SMP Fri Oct 2 22:21:52
  UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

  ---Problem Details---

  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the
  trigger was turning on process accounting and writing to a file hosted
  via an NFSv4 mount.  During the testing, several vmcores were
  captured, and the fingerprint indicates a mutex deadlock situation
  with process accounting.   In the most recent vmcore, it appears that
  the scenario is something like the following:

  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

Bug description:
  Reproduction info:

  set up two LXC containers (although this probably isn't specific to
  LXC containers), and inside each setup ipsec with something similar
  to:

  conn nodeN
  aggressive=yes 
  authby=secret 
  auto=start 
  closeaction=restart 
  dpdaction=restart 
  esp=aes256-aes256gmac-modp1024 
  ike=aes256-sha512-modp1024 
  keyexchange=ikev2 
  left=10.0.3.145 
  leftid=10.0.3.145 
  lifetime=12h 
  reauth=no 
  right=10.0.3.199 
  type=transport 

  
  then repeatedly open connections to the peer, e.g.:

  while true; do ping -c1 10.0.3.199 ; sleep 0.1 ; done

  eventually, the connections will fail with:

  connect: No buffer space available

  the reproduction can be sped up by reducing the xfrm4_gc_thresh, e.g.:

  echo 5 > /proc/sys/net/ipv4/xfrm4_gc_thresh

  
  Once the error occurs, no more connections can be made to the peer (all fail 
with no buffer space available), however after a long period (e.g. overnight) 
the buffers will be cleaned up and connections can be made again.

  this happens even on the latest net-next kernel.

[Kernel-packages] [Bug 1511743] Re: 15.10 server - no keyboard in installer

[Michael Flaig]

very funny ... not!

Anyway: After booting the installer: no keyboard. in Grub Keyboard
Disabling Legacy Keyboard Support didn't do anything.

However: Plugging in a very old USB 1.1 Keyboard works.
Looks to me like the installer is missing some drivers (again?). Maybe related 
to #1244176  ?

I will see what I can find now that the other keyboard works...

Bug description:
  Reproduction info:

  set up two LXC containers (although this probably isn't specific to
  LXC containers), and inside each setup ipsec with something similar
  to:

  conn nodeN
  aggressive=yes 
  authby=secret 
  auto=start 
  closeaction=restart 
  dpdaction=restart 
  esp=aes256-aes256gmac-modp1024 
  ike=aes256-sha512-modp1024 
  keyexchange=ikev2 
  left=10.0.3.145 
  leftid=10.0.3.145 
  lifetime=12h 
  reauth=no 
  right=10.0.3.199 
  type=transport 

  
  then repeatedly open connections to the peer, e.g.:

  while true; do ping -c1 10.0.3.199 ; sleep 0.1 ; done

  eventually, the connections will fail with:

  connect: No buffer space available

  the reproduction can be sped up by reducing the xfrm4_gc_thresh, e.g.:

  echo 5 > /proc/sys/net/ipv4/xfrm4_gc_thresh

  
  Once the error occurs, no more connections can be made to the peer (all fail 
with no buffer space available), however after a long period (e.g. overnight) 
the buffers will be cleaned up and connections can be made again.

  this happens even on the latest net-next kernel.

[Kernel-packages] [Bug 1505564] Re: Soft lockup with "block nbdX: Attempted send on closed socket" spam

[Rafael David Tinoco]

I'm attaching the crash tool output from the 3.13 kernel dump.

Much likely related to the situation already found in the following case:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413540

Handled by Chris Arges and I on LKML discussions with Ingo and Linus:
-> http://www.kernelhub.org/?p=2=683682

FOR NOW, it is LIKELY that I'll rely on already known recommendations for 
Proliant (including 
the ones related to X2APIC mode): 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1417580

So we can TRY TO GUARANTEE that there are no LOST IRQs (IPIs) using the 
firmware you're using.
Hopefully with the proper APIC mode set, like HP recommends, we will not have 
those IPIs problems.

OBS: Whenever IPIs are lost (we've seen this on some nested KVMs and some buggy 
HW) 
we can be locked up in the SMP callback state machine. This means that the 
state machine 
looses IPIs ACKs and the state machine loops forever trying to shutdown the CPU 
for the 
SMP task queue to continue. 

I'll provide SOON a comment with SUGGESTIONS and asking for FEEDBACK.



For now, from the 3.13 kernel dump, the most interesting part:

We had 7 CPUs executing the migration kernel thread (for the SMP
callback state machine execution):

 migration tasks (state machine loop)

>93  2   4  8808147b47d0  RU   0.0   0  0  [migration/4]
>   118  2   9  881814a2c7d0  RU   0.0   0  0  [migration/9]
>   123  2  10  88081404c7d0  RU   0.0   0  0  [migration/10]
>   128  2  11  881814a4c7d0  RU   0.0   0  0  [migration/11]
>   138  2  13  881814a647d0  RU   0.0   0  0  [migration/13]
>   165  2  18  8810149ec7d0  RU   0.0   0  0  [migration/18]
>   195  2  24  881014a647d0  RU   0.0   0  0  [migration/24]

This logic will try to migrate tasks from one CPU to another. In order for that 
to happen they have to 
rely on the state machine logic of shutting CPUs down before migrating the 
tasks (turning off
IRQs, etc). The state machine - shutting down the CPUs on phases - relies on 
the SMP callbacks bellow. 

We had 3 CPUs in a part of the kernel that we have already identified to
be problematic under certain conditions and/or HW.
