[Kernel-packages] [Bug 1767857] Re: Kernel 4.4.0-122 Breaks qemu-system-x86

[ChristianEhrhardt]

Hmm,
so it is not even burning CPU for anything neither in the Host (usr ~=qemu, sys 
~=kernel) nor in the guest itself (~=guest).
The KVM exits confirm that, it doesn't do a a lot entry/exit is the pass in/out 
of guest context and the only meaningful exit means it emulates an instruction.

So if it is not hogged on a CPU it is waiting for something.
Unfortunately this is too windows and x86-arch specific for me to read,
even if you get the info. BTW getting the info what instructions it is
spinning on can be done via [1] - this might be helpful for others
coming by to help. To bad that I still can't reproduce that locally :-/,
but at least I haven't heard of anyone else hitting this yet so it must
be sort of special to maybe your guest?

Especially I can't see yet how a host kernel update would trigger this :-/
Sorry, but this is up for the kernel Team to consider the changes that happened 
between those versions in regard to this issue.

[Kernel-packages] [Bug 1768115] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From p...@au1.ibm.com 2018-05-09 00:25 EDT---
Is it essential to have two NUMA nodes for the guest memory to see this bug? 
Can we reproduce it without the NUMA node stuff in the xml?

  No Internet when waking from suspend

Status in linux package in Ubuntu:

Bug description:
  Ever since I updated my computer later last week I have had no
  internet access after waking from a suspend. This is all I get as a
  response to these ping commands:

  $ ping google.ca
  PING google.ca (216.58.217.195) 56(84) bytes of data.

  $ ping 8.8.8.8
  PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

  localhost works, and I am still able to login to my router over
  wireless. No other computer or phone in my house has any problem with
  the internet, so the problem is specific only to my computer and only
  after the software update.

  the nm-applet is alive and I am able to see the wireless connections
  available to me. If I reconnect to the wifi connection it makes no
  difference.

  If I run "sudo service network-manager restart" it also makes no
  difference.

  The only solution I have found so far to fix the problem is to
  completely restart the computer.

  Any help or advice would be appreciated. If I missed some valuable
  information let me know and I will come back with more info.

  New

Bug description:
  When you press the hotkey to adjust the screen brightness, the
  brightness level indicator will change accordingly, but the actual
  brightness does not.

  And from watching the brightness file in
  /sys/class/backlight/amdgpu_bl0, when the brightness control hotkey
  was pressed, it will change the value here (1~255).

  $ ls /sys/class/backlight/
  amdgpu_bl0  intel_backlight

  This issue existed since 16.04.2 + 4.8 HWE kernel.

[Scott Testerman]

With mainline kernel 4.17rc4, flip_done is still timing out, so it's
exactly the same behavior as the 18.04LTS kernel.

  Which is a bit annoying since I get a KDE warning on the battery.

  My guess is that the issue is in the bluetooth rather in the upowerd
  since the reporting in the /sys/devices shows battery level of 0

  Steps:
  1. Install the ubuntu 18.04 on the machine of Lenovo P520.
  2. Login system.
  3. Plug in an external headset to record and playback in front and rear panel.

  Expected result:
  Output and input audio should work in front and rear panel.

  Actual result:
  Front panel audio doesn't work at all.
  Just output audio working, input audio does't work in rear panel.

  SRU Document:

  [Impact]

  We have several Lenovo machines like Lenovo P520 which have 2 analogue
  audio codecs on them, the internal speaker and front headset are
  connected to the 1st codec, the Rear mic, Line in and Line out are
  connected to the 2nd codec. So far, under ubuntu 18.04 with the alsa-
  lib/libasound2 v1.1.3-5, only the audio devices (internal speaker and
  front headset) on the 1st codec can work. To make all audio devices
  work on this machine, upstream provided 3 patches for kernel audio
  driver and 5 patches for alsa-lib. The kernel patches are already in
  the linux-4.12, so this is not a problem anymore under 18.04 since we
  use linux-4.15 in 18.04. For the 5 patches of alsa-lib, we need to
  backport them to v1.1.3-5, the 5 patches are list as below:

  2b9b3f01 ucm: Assure the user input card name not to exceed max size of card 
long name (it is in the alsa-lib v1.1.4)
  4b9297e6 ucm: Load device-specific configuration file based on the card long 
name (it is in the alsa-lib v1.1.4)
  b7e56af8 conf/ucm: Add dual HD-audio codecs config for Lenovo (it is in the 
alsa-lib v1.1.6)
  181f8e25 ucm: adding the folder of card_long_name when finding verb conf file 
(it is in the alsa-lib v1.1.6+)
  81db276f conf/ucm: increase the input volume for LineIn (it is in the 
alsa-lib v1.1.6+)

  Some explanation for these 5 patches, to make the audio work, the
  alsa-lib needs to add an audio configuration file and verb conf file
  for lenovo machines with dual codecs, these two files are put in a
  folder named by card_long_name, and the name of configuration file
  itself is also named by card_long_name, this is implemented by the
  patches of NO. 3rd and 5th.

  But the alsa-lib v1.1.3-5 itself doesn't support to search conf file with 
card_long_name, it only support searching with card_name, So we need to 
backport 3 patches to let alsa-lib v1.1.3-5 support to search with 
card_long_name, these 3 patches are No. 1st, 2nd and 4th.
   
  [Test Case]

  On the Lenovo machines with dual codecs (p520), I insatlled the
  libasound2 v1.1.3-5ubuntu1 and libasound2-data v1.1.3-5ubuntu1, the
  alsa-lib can find the conf file and can parse the conf file
  successfully, and I tested the internal speaker, front headset, rear
  mic, line out and line in, all audio devices work well.

  On a HP and Dell machines without dual codecs, I insatlled the
  libasound2 v1.1.3-5ubuntu1 and libasound2-data v1.1.3-5ubuntu1, the
  alsa-lib can't find conf file by card_long_name and card_name, the
  pulseaudio will drive the sound card as before, so all audio functions
  worked well as before.

  [Regression Potential]

  After adding these 5 patches, there 2 two changes introduced into the
  alsa-lib v1.1.3-5ubuntu1:

  1) before: only have folder and conf files named by card_name; after: has one 
folder and conf file named by card_long_name, this folder and conf file will 
not affect others,
  2) before: the ucm parser will search the conf file/folder by card_name only; 
 after: the ucm parser will search the conf file/foler by card_long_name first, 
if it fails, it will fallback to use card_name to search again. So this change 
is compatible with old version.

  There is no regression since there is only one folder named by
  card_long_name in v1.1.3-5ubuntu1, if it runs on lenovo machine with
  dual codecs, it will find the conf file by card_long_name, if it runs
  on other machines, the search by card_long_name will definitely fail
  and fall back to search by card_name, then it will be same as before.
  So the objective of these 5 patches is to let lenovo machines with
  dual codecs find the conf file

[Kernel-packages] [Bug 1769236] Re: CPU frequency stuck at minimum value

[Glen Ditchfield]

Upstream kernel 4.17.0-rc4 didn't change performance.

Recall that I installed Kubuntu.  Since then I have installed ubuntu-
gnome-desktop, in case that provided some missing configuration file.

With either kernel, I get this behavior:
- I boot the laptop.
- Instead of logging into a desktop environment, I use virtual terminals.
- Usually /proc/cpuinfo shows all 8 CPUs running at 900 MHz, give or take a few 
Hz.  Sometimes it shows 400 MHz, but it soon rises to 900 MHz.
- I run the c-ray benchmark.  CPU frequency rises to 2400 MHz, and stays there 
for tens of seconds, then drops to 400 MHz.
- The laptop does not become warm, and the fans do not spin up.
- I kill c-ray.  A few minutes later, CPU frequency rises from 400 MHz back up 
to 900 MHz.
- kern.log contains "intel_powerclamp: Start idle injection to reduce power" 
within seconds of  the times when the frequency drops to 400 MHz, and 
"intel_powerclamp: Stop forced idle injection" when it rises to 900 MHz.

Is the cooling system failing to activate the fans, or overreacting to
CPU temperatures in some way?

Title:
  CPU frequency stuck at minimum value

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I installed the Kubuntu variant of Ubuntu 18.04 on a new HP Spectre 13
  laptop.  Performance is poor.  The CPU (an i7-8550U) is running at
  400MHz, and never speeds up, even when running some of the Phoronix
  Test Suite benchmarks.

  I can use cpupower to switch to the "performance" cpufreq governor,
  but cannot change the frequency with either governor.

  Here is the output of some experiments I ran while Phoronix's c-ray test was 
running.

  "drm timed out" with driver i915 + Intel Mobile GM965/GL960 Integrated
  Graphics with Kernel 4.15

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  With Ubuntu 18.04 + Kernel 4.15, at boot time there are many periods when the 
boot freezes before the timeout of 10 seconds with Intel Mobile GM965/GL960 
Integrated Graphics (driver i915).
  In total it is 198 seconds that are lost in these timeouts during boot, more 
than 3 minutes!

  Regression is present since linux kernel 4.8 (with Ubuntu 16.04).

  To fix, explicitly disable the port with an i915 module setting with 
video=SVIDEO-1:d in the kernel command line parameter in the bootloader.
  1/ sudo gedit /etc/default/grub
  2/ add "video=SVIDEO-1:d" to "GRUB_CMDLINE_LINUX_DEFAULT" line
  3/ sudo update-grub

  After applying this, the system boots up much faster, there are no
  "drm ... timed out" messages.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()

[Joseph Salisbury]

If there are too many required patches, a bug fix would not pass the SRU
requirements[1].  The SRU process requires the least amount of changes
to implement the fix.

How did you go about identifying all of the required commits in the bug
description?  Is that the minimum number of commits required to fix the
bug?  Is it possible to "Reverse" bisect down to a fewer number of
commits?

Is there a specific commit that you know of that introduced this bug in
Bionic?  One other option could be to find the offending commit and
revert it.

  Below are the steps to replicate the issue

  We are doing continuous BLE scanning and monitoring the advertisements
  from reference device. After long periods of capture (several hours),
  the radio stops capturing advertisements and won't start again until
  we power cycle the box or manually unload/load the module via modprobe

[Kernel-packages] [Bug 1768971] Re: Warnings/hang during error handling of SATA disks on SAS controller

[dann frazier]

** Description changed:

  [Impact]
  When a SATA device, attached to a SAS controller, begins generating errors 
(e.g. device failing, or someone yanked it), the SAS error handling will 
complete, but may leave zombie ATA commands that never get properly 
processed/freed. This can cause some ugly messages on the console, and 
eventually leads to a system hang-up.

  [Test Case]
  I don't have a reliable reproducer for this, but one possible test is to yank 
an active/hotpluggable SATA disk from its controller and see if the above 
symptoms occur.
  
+ [Fix] 
+ The solution here is to call into libata to have it process the remaining 
commands, allowing us to free up the zombie commands, preventing the leak and 
eventual starvation.
+ 
  [Regression Risk]
  This is a clean cherry-pick from upstream, so any regressions should have 
upstream support. As of this writing, there are no changesets in linux-next 
marked as Fixing this commit, implying that upstream has not yet found/fixed 
any bugs related to it.

  When a SATA device, attached to a SAS controller, begins generating errors 
(e.g. device failing, or someone yanked it), the SAS error handling will 
complete, but may leave zombie ATA commands that never get properly 
processed/freed. This can cause some ugly messages on the console, and 
eventually leads to a system hang-up.

  [Test Case]
  I don't have a reliable reproducer for this, but one possible test is to yank 
an active/hotpluggable SATA disk from its controller and see if the above 
symptoms occur.

  [Fix] 
  The solution here is to call into libata to have it process the remaining 
commands, allowing us to free up the zombie commands, preventing the leak and 
eventual starvation.

  [Regression Risk]
  This is a clean cherry-pick from upstream, so any regressions should have 
upstream support. As of this writing, there are no changesets in linux-next 
marked as Fixing this commit, implying that upstream has not yet found/fixed 
any bugs related to it.

[Kernel-packages] [Bug 1757445] Re: Suspend does not always resume

[cascagrossa]

Same fault with Dell Inspiron 5557. On resume it takes about 4 seconds
and then the lock screen appears, when trying to unlock it accepts four
to five digits and then hangs completely (nor REISUB works). The only
option is manually power off.

Bug description:
  Dell XPS 13 9350 on AC power left running overnight, suspends after a
  given timeout. When coming back the next morning sometimes the laptop
  resumes to an aubergine desktop (just the screen, no GDM) and cursor
  and sits there forever. Sometimes it resumes to a black screen and
  cursor.

[Kernel-packages] [Bug 1768115] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From mdr...@us.ibm.com 2018-05-08 16:37 EDT---
Hit another instance of the RAM inconsistencies prior to resuming guest on 
target side (this one is migrating from boslcp6 to boslcp5 and crashing after 
it resumes execution on boslcp5). The signature is eerily similar to the ones 
above... the workload is blast from LTP but it's strange that 3 out of 3 so far 
have been the same data structure. Maybe there's a relationship between 
something the process is doing and dirty syncing?

For this run I included traces of the various stages of memory migration
on the QEMU side relative to dirty bitmap sync (attached above). The 3
phases are:

"ram_save_setup": enables dirty logging and sets up data structures used
for tracking dirty pages. does the initial bitmap sync. QEMU keeps it's
own copy which gets OR'd with the one provided by KVM on each bitmap
sync. There's 2 blocks (ram-node0/ram-node1) each with their own bitmap
/ KVM memslot since guest was defined with 2 NUMA nodes. Only ram-node0
would be relevant here since it has offset 0 in guest physical memory
address space.

"ram_save_pending": called before each iteration to see if there are
pages still pending. When number of dirty pages in the QEMU bitmap drop
below a certain value it does another sync with KVM's bitmap.

"ram_save_iterate": walks the QEMU dirty bitmap and sends corresponding
pages until there's none left or some other limit (e.g. bandwidth
throttling or max-pages-per-iteration) is hit.

"ram_save_pending"/"ram_save_iterate" keeps repeating until no more
pages are left.

"ram_save_complete" does a final sync with KVM bitmap, sends final set
of pages, then disables dirty logging and completes the migration.

"vm_stop" denotes with the guest VCPUs have all exited and stopped
execution.

There's 2 migrations reflected in the posted traces, the first one can
be ignored (everything between first ram_save_setup and first
ram_save_complete), it's just a backup of the VM. After that the VM is
backup up it resumes execution and that's the state we're migrating here
and seeing a crash with on other end.

The sequences of events in this run are comparable to previous
successful runs, no strange orderings or missed calls to sync with KVM
dirty bitmap/etc. The condensed version of the trace are below, but it
looks like there's a sync prior to vm_stop, and a sync afterward, and
given that these syncs are OR'd into a persistent bitmap maintained by
QEMU, there's shouldn't be any loss of dirty page information with this
particular ordering of events.

I'm not sure here whether the xenial nomination is meant to apply to the
linux package. If so ...

That list of kernel patches is probably correct for bionic. Xenial
however is going to require additional patches. The wmm rules are only
available with the newer, extensible regdb format which is supported in
4.15 but not in 4.4. So to have any hope of using the wmm rules with 4.4
there would need to be a number of additional backports.

The wireless-regdb changes for xenial will also need some consideration.
With the new regdb format there was also a transition to loading the
regdb as a firmware file signed with a key whose public half is baked
into the kernel. My thinking is that we should just stop building the
regdb files from source and ship the pre-built (and pre-signed) upstream
binaries. I think this should be fine for xenial but we will need to
verify.

Bug description:
  From time to time, CPU vendors release updates to microcode that can
  be loaded into the CPU from the OS.  For x86, we have these updates
  available in the archive as amd64-microcode and intel-microcode.

  Sometimes, these microcode updates have addressed security issues with
  the CPU.  They almost certainly will again in the future.

  We should ensure that all users of Ubuntu on baremetal x86 receive
  these security updates, and have them applied to the CPU in early boot
  where at all feasible.

  Because these are hardware-dependent packages which we don't want to
  install except on baremetal (so: not in VMs or containers), the
  logical place to pull them into the system is via the kernel, so that
  only the kernel baremetal flavors pull them in.  This is analogous to
  linux-firmware, which is already a dependency of the linux-
  image-{lowlatency,generic} metapackages, and whose contents are
  applied to the hardware by the kernel similar to microcode.

  So, please update the linux-image-{lowlatency,generic} metapackages to
  add a dependency on amd64-microcode [amd64], intel-microcode [amd64],
  and the corresponding hwe metapackages also.

  Please time this change to coincide with the next updates of the
  microcode packages in the archive.

  I believe we will also need to promote the *-microcode packages to
  main from restricted as part of this (again, by analogy with linux-
  firmware).

Title:
  Ubuntu Xenial HWE Kernel 4.13 Direct Sync Write Performance Regression

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi Ubuntu,

  Just found out today that when using Ubuntu Xenial HWE kernel 4.13 in
  a VM on top of Proxmox VE 5.1.x, the direct synchronous write
  performance is 93% slower than on kernel 4.4. Kernel 4.13 direct sync
  4KB write could only achieve 303KB/s while kernel 4.4 could achieve
  4.5MB/s.

  The VM is using ext4 filesystem and running on top of ZFS ZVOL on ZFS
  RAID1 with virtio-scsi, qemu disk cache none, and qemu disk discard
  enabled. The underlying physical disks are Samsung Enterprise SSD
  SM863a 480GB series.

  The reason I need to run kernel 4.13 to mount CephFS Luminous with
  kernel client. Hopefully CephFS Luminous kernel client will be back
  ported to kernel 4.4 in the near future.

  Is this from Ubuntu Xenial kernel 4.13 performance regression or from
  Proxmox VE 5.1 kernel 4.13 virtio-scsi performance regression?

  The test results:

  Ubuntu Xenial HWE Kernel 4.13 Direct Sync Write Performance Regression

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi Ubuntu,

  Just found out today that when using Ubuntu Xenial HWE kernel 4.13 in
  a VM on top of Proxmox VE 5.1.x, the direct synchronous write
  performance is 93% slower than on kernel 4.4. Kernel 4.13 direct sync
  4KB write could only achieve 303KB/s while kernel 4.4 could achieve
  4.5MB/s.

  The VM is using ext4 filesystem and running on top of ZFS ZVOL on ZFS
  RAID1 with virtio-scsi, qemu disk cache none, and qemu disk discard
  enabled. The underlying physical disks are Samsung Enterprise SSD
  SM863a 480GB series.

  The reason I need to run kernel 4.13 to mount CephFS Luminous with
  kernel client. Hopefully CephFS Luminous kernel client will be back
  ported to kernel 4.4 in the near future.

  Is this from Ubuntu Xenial kernel 4.13 performance regression or from
  Proxmox VE 5.1 kernel 4.13 virtio-scsi performance regression?

  The test results:

Title:
  Ubuntu Xenial HWE Kernel 4.13 Direct Sync Write Performance Regression

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi Ubuntu,

  Just found out today that when using Ubuntu Xenial HWE kernel 4.13 in
  a VM on top of Proxmox VE 5.1.x, the direct synchronous write
  performance is 93% slower than on kernel 4.4. Kernel 4.13 direct sync
  4KB write could only achieve 303KB/s while kernel 4.4 could achieve
  4.5MB/s.

  The VM is using ext4 filesystem and running on top of ZFS ZVOL on ZFS
  RAID1 with virtio-scsi, qemu disk cache none, and qemu disk discard
  enabled. The underlying physical disks are Samsung Enterprise SSD
  SM863a 480GB series.

  The reason I need to run kernel 4.13 to mount CephFS Luminous with
  kernel client. Hopefully CephFS Luminous kernel client will be back
  ported to kernel 4.4 in the near future.

  Is this from Ubuntu Xenial kernel 4.13 performance regression or from
  Proxmox VE 5.1 kernel 4.13 virtio-scsi performance regression?

  The test results:

Title:
  Ubuntu Xenial HWE Kernel 4.13 Direct Sync Write Performance Regression

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi Ubuntu,

  Just found out today that when using Ubuntu Xenial HWE kernel 4.13 in
  a VM on top of Proxmox VE 5.1.x, the direct synchronous write
  performance is 93% slower than on kernel 4.4. Kernel 4.13 direct sync
  4KB write could only achieve 303KB/s while kernel 4.4 could achieve
  4.5MB/s.

  The VM is using ext4 filesystem and running on top of ZFS ZVOL on ZFS
  RAID1 with virtio-scsi, qemu disk cache none, and qemu disk discard
  enabled. The underlying physical disks are Samsung Enterprise SSD
  SM863a 480GB series.

  The reason I need to run kernel 4.13 to mount CephFS Luminous with
  kernel client. Hopefully CephFS Luminous kernel client will be back
  ported to kernel 4.4 in the near future.

  Is this from Ubuntu Xenial kernel 4.13 performance regression or from
  Proxmox VE 5.1 kernel 4.13 virtio-scsi performance regression?

  The test results:

Title:
  Ubuntu Xenial HWE Kernel 4.13 Direct Sync Write Performance Regression

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi Ubuntu,

  Just found out today that when using Ubuntu Xenial HWE kernel 4.13 in
  a VM on top of Proxmox VE 5.1.x, the direct synchronous write
  performance is 93% slower than on kernel 4.4. Kernel 4.13 direct sync
  4KB write could only achieve 303KB/s while kernel 4.4 could achieve
  4.5MB/s.

  The VM is using ext4 filesystem and running on top of ZFS ZVOL on ZFS
  RAID1 with virtio-scsi, qemu disk cache none, and qemu disk discard
  enabled. The underlying physical disks are Samsung Enterprise SSD
  SM863a 480GB series.

  The reason I need to run kernel 4.13 to mount CephFS Luminous with
  kernel client. Hopefully CephFS Luminous kernel client will be back
  ported to kernel 4.4 in the near future.

  Is this from Ubuntu Xenial kernel 4.13 performance regression or from
  Proxmox VE 5.1 kernel 4.13 virtio-scsi performance regression?

  The test results:

  I have noticed this ACPI error persisting in my syslog and dmesg. Based on 
what I have learnt from  ACPI, acpitool -w and lspci, I think the error is 
related to Namespaces provided in the DDST on \_SB_.PCI0.XHC_.RHUB.HS11, which 
I think concerns the Root → System bus tree → PCI bus  → USB controller: Intel 
Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) in my system. I 
have not found what .RHUB.HS11 refers too. I have tried changing my UEFI USB 
settings but to no avail. Appreciate help to fix this bug. 

  I reported it as a question

  Problem Description: Migration Guest running with IO stress
  crashed@security_file_permission+0xf4/0x160 after couple of
  migrations.

  Steps to re-create:

  Source host - boslcp3
  Destination host - boslcp4

  1.boslcp3 & boslcp4 installed with latest kernel
  root@boslcp3:~# uname -a
  Linux boslcp3 4.15.0-20-generic #21+bug166588 SMP Thu Apr 26 15:05:59 CDT 
2018 ppc64le ppc64le ppc64le GNU/Linux
  root@boslcp3:~#

  root@boslcp4:~# uname -a
  Linux boslcp4 4.15.0-20-generic #21+bug166588 SMP Thu Apr 26 15:05:59 CDT 
2018 ppc64le ppc64le ppc64le GNU/Linux
  root@boslcp3:~#

  2. Installed guest boslcp3g1 with kernel and started LTP run from
  boslcp3 host

  root@boslcp3g1:~# uname -a
  Linux boslcp3g1 4.15.0-15-generic #16+bug166877 SMP Wed Apr 18 14:47:30 CDT 
2018 ppc64le ppc64le ppc64le GNU/Linux

  3. Started migrating boslcp3g1 guest from source to destination & viceversa.
  4. After couple of migrations it crashed at boslcp4 & enters into xmon
