[Kernel-packages] [Bug 1753662] Re: [i40e] LACP bonding start up race conditions

[Nobuto Murata]

The test is still in progress, but so far
d38162e4b5c643733792f32be4ea107c831827b4 looks good (1 of 37). Since I
already downloaded the kernel locally, please go ahead to build the next
one. Thanks,

Title:
  [i40e] LACP bonding start up race conditions

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.

[Kernel-packages] [Bug 1750937] Re: 4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and 16.04) by an insufficient compiler!

[Ross Campbell]

Multiple Ubuntu 14.04 systems with newer compilers, and I don't really
want to remove them...

Can we get updated compilers in the ubuntu-toolchain-r/test ppa
... or optional kernels without 'retpoline'?

ok... this issue is FAR more widespread than I see reported here. I just
upgraded my other Ubuntu 14.04 system -- this one has an NVidia GeForce
1060, and my nvidia driver won't load, it instead loads Nouveau

... and as above, the same error in /var/log/syslog:

Mar 13 21:55:09 Godzilla kernel: [   20.720161] nvidia: version magic
'3.13.0-143-generic SMP mod_unload modversions ' should be

This is running the Nvidia driver 384.111

So, I would suspect that anyone running Ubuntu 14.04 with a NVidia
graphics card who upgrades to kernel 3.13.0-143 will have problems with
their system immediately upon reboot...

[fu2qi4]

to Sebastien (olorinseb) about " infinite login loop problem":
It's another bug, reported here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891960

https://devtalk.nvidia.com/default/topic/1029683/suspend-swap-group-
failed-resume-swap-group-failed-nvidia-390-25/

According to Debian staff, it's Nvidia bug, not Debian's.
This bug is supposed to be fixed in new Nvidia  driver's update

Title:
  During boot process, system goes to sleep

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to 16.04, my computer goes to sleep during the boot process, 
shortly after I entered the passphrase to unlock my LVM. When I wake it up, I’m 
at the graphical login prompt. I type my user password, press enter and it goes 
to sleep again. When I wake it up, I’m in my working Lubuntu desktop. This 
happens every time I boot. And it’s quite annoying.
  Please tell me which additional information I can provide to help fix this 
bug.

[Kernel-packages] [Bug 1751676] Re: Synaptics' touchpad not detected in 'CyberpowerPC Tracer II' laptop after kernel, system and multiple packages upgrade (for instance: CUDA, libinput, etc.

[Pedro]

As expected I had a hard time trying to test the latest upstream kernel.
Haven't found a way to do it  without running into the expected "out-of-
tree modules" uninstall, specifically nvidia (with bbswitch).

Having been into this terrain before, I don't think I will proceed to
uninstall the nvidia modules given that it might bring me _other_ video-
related problems on my work laptop. I guess for now I can live with an
external USB mouse. Once I move work into a new box I'll go ahead and
re-try the procedure.

Thanks for the help and sorry for that :$

  Synaptics' touchpad not detected in 'CyberpowerPC Tracer II' laptop
  after kernel, system and multiple packages upgrade (for instance:
  CUDA, libinput, etc.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Installed ubuntu 16.04 a while ago and touchpad was working. It does work as 
well on LiveCDs.
  After upgrading kernel and some system packages (i've even removed 
xorg-input-synaptics), touchpad does not even show in `xinput list`. USB mouse 
works though.

  I've skimmed dozens of pages in askubuntu and stackexchange to no avail:
  
https://unix.stackexchange.com/questions/28736/what-does-the-i8042-nomux-1-kernel-option-do-during-booting-of-ubuntu

  https://ubuntuforums.org/showthread.php?t=2323564
  https://ubuntuforums.org/showthread.php?t=2352021

  Most of these revolved around tampering with the 
`GRUB_CMDLINE_LINUX_DEFAULT=` argument in `/etc/default/grub` and removing 
`xserver-xorg-input-synaptics` package along with confs.

Bug description:
  My laptop (Lenovo T440) freezes when starting Xorg (lightdm) only
  after installing the latest ubuntu kernel for 17.10, linux-
  image-4.13.0-32-generic.

  Am running Xorg instead of MIR due to MIR crashing when I initially
  upgraded from 17.04 to 17.10, but that's a different problem for a
  different day. It's been running with Xorg stably for at least 2-3
  months.

  If I boot with the previous kernel version on my /boot (linux-
  image-4.13.0-25-generic), everything works fine.

  If I boot with the latest mainline kernel from the Ubuntu mainline
  repo (4.15.0), everything works.

  Using grub's option to run "Recovery Mode" for the 4.13.0-32 kernel, I
  am able to use the CLI and access the encrypted root filesystem, which
  is how I generated the apport repo that's attached. It's only when
  telling it to continue Normal booting that it freezes, which is why I
  suspect the problem of being Xorg.

  When the system freezes, the fan starts to spin up. I cannot switch
  virtual consoles using CTRL-ALT-F{1-7}. CTRL-ALT-DEL pressed
  repeatedly doesn't do anything. To reboot, I have to hold the power
  button until the system powers off.

using repo HWE kernel (linux-image-generic-hwe-16.04): 
 4.13.0.36.55 ---> hibernation broken

using mainline kernel (linux-image-4.15.9-041509-generic):
 4.15.9-041509-generic ---> hibernation works

how to install (bc people asked and I don't want to clutter bug report):

[Kernel-packages] [Bug 1746088] Re: [Ubuntu 16.04.4] Unable to analyze the vmcore generated by kdump on 4.13.0-26-generic kernel

[Dimitri John Ledkov]

@breno re: point release meaning vs updates

Please note point releases refer to installation media only, which is a
consistent snapshot of cloud images, container images, server ISO, d-i,
etc. Built from xenial-updates & xenial-security pockets as published at
the time of the respin. xenial-updates/-security themselves are a moving
target.

It's impossible to ship something in "16.04.2" today, as there is no
package archive that refers to "16.04.2". One simply continuously ships
updates in xenial-updates.

Thus the point of point-releases installation media, is to have
installers available with a newer kernel which hopefully supports more
hardware, and newer packages making post-install security/updates
upgrades quicker & smaller, as one does not need to catch up 2 years+ of
updates, just a few weeks of updates.

This issue does not appear to impact the installation media /
installation success, therefore it is not critical to ship in
installation media as respun for a point release. Hence it is targetted
to ship simply as any other SRU in xenial-updates.

Once the solution to this bug is found that is.

  == Comment from Hari Krishna Bathini ==

  There are quite a few commits (all available upstream) that are needed for
  crash tool to work fine. I think the right thing to do here would be to use
  the latest crash tool version 7.2.0 to go with the kernel update. Also, the
  below commit would be needed on top of 7.2.0 crash utility:

commit c8178eca9c74f81a7f803a58d339635cc152e8d9
Author: Dave Anderson 
Date:   Thu Nov 9 11:39:05 2017 -0500

  Update for support of Linux 4.14 and later PPC64 kernels where the
  hash page table geometry accomodates a larger virtual address range.
  Without the patch, the virtual-to-physical translation of user space
  virtual addresses by "vm -p", "vtop", and "rd -u" may generate an
  invalid translation or otherwise fail.
  (hbath...@linux.vnet.ibm.com)

  Similar thing holds true for makedumpfile tool..

  Thanks

[Kernel-packages] [Bug 1755624] Re: With intel-microcode 3.20180312, kernel reports as broken spectre v2 microcode

[Michael Marley]

I see the same issue on my Skylake desktop (sig=0x506e3).  The microcode
updates at startup (microcode: microcode updated early to revision 0xc2,
date = 2017-11-16) but I still get "Intel Spectre v2 broken microcode
detected; disabling Speculation Control".  I also tested it on Ivy
Bridge, Broadwell, and another Skylake system (0x406e3) and it works
properly on all those.

  And indeed, none of ibrs, ibpb, or stibp show up in /proc/cpuinfo.
  Other testers of the updated microcode report seeing the same thing.

  The processor this is being tested on is:

  model name  : Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz
  stepping: 9

  The test for the microcode is in https://git.launchpad.net/~ubuntu-
  kernel/ubuntu/+source/linux/+git/bionic/tree/arch/x86/kernel/cpu/intel.c#n178
  ; specifically, it looks like bad_spectre_microcode(c) is returning

  I just upgraded to bionic from artful and the kernel's graphics stack
  seems to be hosed. I can get text consoles, but neither plymouth nor
  Wayland GDM sessions work.

  X11 sessions do work however, e.g. by disabling Wayland for GDM3 in
  custom.conf or running startx from the console, however to get to that
  point you need to boot into a recovery session from the bootloader to
  avoid invoking the bootsplash, then proceed to boot normally from the
  recovery menu.

  If I boot into the 4.13 kernel I had leftover from artful, everything
  works fine.

  This is on a MacBookPro12,1 with an i7-5557U and Intel Iris 6100
  (Broadwell GT3) integrated GPU.

Re: [Kernel-packages] [Bug 1735420] Re: Avoid creation of /dev/kvm in Xenial KVM virtual machines on s390x

[Frank Heimes]

Hi Joe,
yes that should be easy for me to test.
I think I only need to run that patched xenial kernel in a KVM virtual
machine and the device shouldn't be there - however running it directly in
LPAR should show the device.

I'm off on Wednesday, but will test it later this week.

Bye, Frank

[Kernel-packages] [Bug 1735420] Re: Avoid creation of /dev/kvm in Xenial KVM virtual machines on s390x

[Joseph Salisbury]

Frank, Is there a way to test a test kernel I built?  I built a Xenial
test kernel with a back port of commit a411edf1320e ("KVM: s390: vsie:
add module parameter "nested"").

I'm not sure off hand if just this commit is needed or if there are
others as well.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1735420/

[Kernel-packages] [Bug 1728565] Re: Desktop (screen) corrupted after upgrade to 17.10

[Martin Lees]

I had this problem with 17.10 and reverted to 16.04 which has been
working fine until I have just done a software update and now have the
same issue with 16.04. The work around using the Suspend option still
works but I still have the problem after booting.

Bug description:
  I upgraded my NC10 netbook from Ubuntu Mate 16.04 to 17.04 (which worked 
okay) and then to 17.10. When starting up and automatically logging in I can 
see the right hand quarter of the screen but the left three quarters are mostly 
black with multicolour icons repeated across the top 3mm, a light grey bar 
below this  8mm high with a darker grey interruption just over half way across 
and two small horizontal white lines directly below this. The mouse pointer is 
displayed where ever it is positioned and the right hand menus work as 
expected. The computer is unusable in this condition.
  Dropping to a terminal with Ctrl+Alt+F1 has the same screen corruption and 
the prompt is spread across multiple lines as a series of dots and dashes - 
completely unreadable. It seems the video driver is not working for this 
machine in this release. The previous release showed it was using the standard 
Intel open source drivers. Issue persists when PC rebooted. Power up shows 
Samsung boot screen then light grey screen with small dark grey border then the 
corruption described above grey background and green pattern (probably the boot 
image corrupted then clearing to corruption over black background then to the 
state described, i.e. mostly black with a bit of desk top and some corrupted 
stuff at top.

  I can probably ssh in to this machine to grab logs as required so
  please let me know what I can do to help debug and get my laptop back
  working.

  Computer is a Samsung NP-NC10 with 1GB RAM and Intel Atom CPU.
  (Sorry I didn't find time to test the beta!!!)

Title:
  LAN connection keeps connecting and disconnecting in an infinite loop

Status in linux package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu:
  New

Bug description:
  With Xubuntu 17.10 the following problem occurs on a Lenovo X230 Laptop:
  - Boot from live-ISO
  - Click on network icon in title bar and edit LAN-connection
  - Change MTU from Auto to 1492
  - Connect LAN cable
  => LAN network keeps connecting and disconnecting in an infinite loop

  (No wireless network is configured.)

  The error did not occur on Xubuntu 16.04. The same situation occurs
  with Xubuntu installed on the SSD. I took the ISO for this bug report,
  in order to exclude wrong settings on the installed system.

  This is my first bug report - I hope I did not do too much wrong. If
  necessary, I can provide more information.

Title:
  LAN connection keeps connecting and disconnecting in an infinite loop

Status in linux package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu:
  New

Bug description:
  With Xubuntu 17.10 the following problem occurs on a Lenovo X230 Laptop:
  - Boot from live-ISO
  - Click on network icon in title bar and edit LAN-connection
  - Change MTU from Auto to 1492
  - Connect LAN cable
  => LAN network keeps connecting and disconnecting in an infinite loop

  (No wireless network is configured.)

  The error did not occur on Xubuntu 16.04. The same situation occurs
  with Xubuntu installed on the SSD. I took the ISO for this bug report,
  in order to exclude wrong settings on the installed system.

  This is my first bug report - I hope I did not do too much wrong. If
  necessary, I can provide more information.

Title:
  LAN connection keeps connecting and disconnecting in an infinite loop

Status in linux package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu:
  New

Bug description:
  With Xubuntu 17.10 the following problem occurs on a Lenovo X230 Laptop:
  - Boot from live-ISO
  - Click on network icon in title bar and edit LAN-connection
  - Change MTU from Auto to 1492
  - Connect LAN cable
  => LAN network keeps connecting and disconnecting in an infinite loop

  (No wireless network is configured.)

  The error did not occur on Xubuntu 16.04. The same situation occurs
  with Xubuntu installed on the SSD. I took the ISO for this bug report,
  in order to exclude wrong settings on the installed system.

  This is my first bug report - I hope I did not do too much wrong. If
  necessary, I can provide more information.

Title:
  LAN connection keeps connecting and disconnecting in an infinite loop

Status in linux package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu:
  New

Bug description:
  With Xubuntu 17.10 the following problem occurs on a Lenovo X230 Laptop:
  - Boot from live-ISO
  - Click on network icon in title bar and edit LAN-connection
  - Change MTU from Auto to 1492
  - Connect LAN cable
  => LAN network keeps connecting and disconnecting in an infinite loop

  (No wireless network is configured.)

  The error did not occur on Xubuntu 16.04. The same situation occurs
  with Xubuntu installed on the SSD. I took the ISO for this bug report,
  in order to exclude wrong settings on the installed system.

  This is my first bug report - I hope I did not do too much wrong. If
  necessary, I can provide more information.

[Kernel-packages] [Bug 1754759] Re: LAN connection keeps connecting and disconnecting in an infinite loop

[Markus Baumann]

apport information

** Tags added: apport-collected

** Description changed:

  With Xubuntu 17.10 the following problem occurs on a Lenovo X230 Laptop:
  - Boot from live-ISO
  - Click on network icon in title bar and edit LAN-connection
  - Change MTU from Auto to 1492
  - Connect LAN cable
  => LAN network keeps connecting and disconnecting in an infinite loop
  
  (No wireless network is configured.)
  
  The error did not occur on Xubuntu 16.04. The same situation occurs with
  Xubuntu installed on the SSD. I took the ISO for this bug report, in
  order to exclude wrong settings on the installed system.
  
  This is my first bug report - I hope I did not do too much wrong. If
  necessary, I can provide more information.

   SRU Justification:

  Impact:
  User reports excessive ALUA messages on Ubuntu Trusty, kernel 
Ubuntu-lts-4.4.0-91.114_14.04.1
  Messages appear after a LUN disappears and there are hundreds of them 
flooding the log...

  [263095.795876] sd 3:0:0:129: [alua] Add. Sense: Logical unit not supported

  This causes an intense requeing of the ALUA work queue for 60 seconds
  and it floods the kernel log

  +++ This bug was initially created as a clone of Bug #165215 +++

  ---Problem Description---
  Paul Mackerras has posted a fix to a Radix page fault handler bug in KVM:

  http://patchwork.ozlabs.org/patch/877033/
  " KVM: PPC: Book3S HV: Fix handling of large pages in radix page fault 
handler "

  This is critical for P9 KVM performance. Using an open source database 
workload, we saw an 11% throughput improvement with this patch when the guest 
was backed w/ 2MB hugepages. Without this patch, hugepage backing does not help 
performance compared to base page size. 
   
  ---uname output---
  18.04 lts
   
  Machine Type = 5104-22C 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
Back guest w/ 2MB pages, run a throughput test and compare performance.

  - Luciano built and provided the patch with new Qlogic change on
  Friday last week.

  root@bos1u1p1:~/chavez# ls linux-image*
  linux-image-4.15.0-041500rc9-generic_4.15.0-041500rc9.201801212130_ppc64el.deb
  
linux-image-extra-4.15.0-041500rc9-generic_4.15.0-041500rc9.201801212130_ppc64el.deb

  - I configured and ran same test over weekend and test ran good. KVM
  host did not crash in qlt_free_session_done call like before.

  - So the patch fixed the problem.

  Hi Canonical,

  Please review and consider this a request to pull in commit
  2ce87cc5b269510de9ca1185ca8a6e10ec78c069 please. Thanks!

  "When the compressed ARC feature was added in commit d3c2ae1
  the method of reference counting in the ARC was modified.  As
  part of this accounting change the arc_buf_add_ref() function
  was removed entirely.

  This would have be fine but the arc_buf_add_ref() function
  served a second undocumented purpose of updating the ARC access
  information when taking a hold on a dbuf.  Without this logic
  in place a cached dbuf would not migrate its associated
  arc_buf_hdr_t to the MFU list.  This would negatively impact
  the ARC hit rate, particularly on systems with a small ARC."

[Kernel-packages] [Bug 1720219] Re: Repeated keys stop after a few characters (^@ character spam every second)

[Joseph Salisbury]

I built Xenial and Artful test kernels both with only commit
3b95206110a.  The test kernels can be downloaded from:

Artful: http://kernel.ubuntu.com/~jsalisbury/lp1720219/artful/
Xenial: http://kernel.ubuntu.com/~jsalisbury/lp1720219/xenial/

Can those affected by this bug give these kernels a try?

Bug description:
  Long pressing a key will only repeat a few characters or won't repeat
  at all in the default 17.10 GNOME environment, it affects all keys
  including backspace and arrows.

  It isn't application specific, the problem is always there whether be
  it terminal or firefox.

  Setting the repeat delay to 0 will instantly trigger it, however it
  will still stop after a few characters.

  I freshly installed 17.10 on a Lenovo Ideapad 700, I haven't had the
  problem in 16.04 with GNOME 3.22.

  Edit: Happens in Xorg as well.

[Kernel-packages] [Bug 1755563] Re: dangling symlinks to loaded apparmor policy

[Zygmunt Krynicki]

** Description changed:

  On my artful system running 4.13.0-36-generic I noticed that there are
  dangling symlinks for "raw_data", "raw_sha1" and "raw_abi" files in the
  sysfs path containing loaded apparmor profiles.
  
  Sample of profiles that had dangling symlinks:
  
  
/sys/kernel/security/apparmor/policy/profiles/snap.core.hook.configure.35/raw_data
  
/sys/kernel/security/apparmor/policy/profiles/snap.core.hook.configure.35/raw_abi
  
/sys/kernel/security/apparmor/policy/profiles/snap.core.hook.configure.35/raw_sha1
  
  The following command can be used to find such files:
  
  find /sys/kernel/security/apparmor/policy/profiles -type l -exec sh -c
  "file -b {} | grep -q ^broken" \; -print
  
- It seems that neither xenial (4.4 kernel) nor bionic (4.15 kernel) is
- affected though I didn't perform an extensive investigation.
- 
- EDIT: This is inaccurate, bionic is affected as well. See below.
+ The issue was observed on xenial (4.4 kernel), artful (4.13) and bionic
+ (4.15).
  
  I'm reporting this because according to the apaprmor developer it seems
  "racy" and should not happen.
  
   zyga-ubuntu: no, there shouldn't be a way to remove profiles 
wrong, there is the potential for a race of sorts because the symlink doesn't 
have the same hard reference, but that isn't something you should be seeing
   zyga-ubuntu: the raw_data file should not be going away as long 
as that profile directory exists
  
  It is likely that this problem occurs when snapd generates profiles for
  refreshed snaps or removes profiles for removed snaps but I was not able
  to determine that yet.
  
  I updated my bionic system and noticed non-snap-related dangling symlink when 
the libreoffice package was updated:
  /sys/kernel/security/apparmor/policy/profiles/libreoffice-senddoc.17/raw_data

[Kernel-packages] [Bug 1753662] Re: [i40e] LACP bonding start up race conditions

[Joseph Salisbury]

Yes that is the correct kernel.  The mainline-build-one script uses the
'git describe' command to come up with the name.  That command returns
the closest git tag and not the one that contains it.  So in the case of
commit d38162e4b5c643733792f32be4ea107c831827b4:

git describe d38162e4b5c643733792f32be4ea107c831827b4   
 
v4.12-rc1-13-gd38162e


However, that test kernel is actually using commits in -rc4, which you can see 
if the '--contains' option is given to git describe:

git describe --contains d38162e4b5c643733792f32be4ea107c831827b4
v4.12-rc4~20^2~4^2~3


I can continue to build the kernels, there are about 3 left.  It only takes 
about 15 minutes to build the kernel for me.

  [i40e] LACP bonding start up race conditions

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.

[Kernel-packages] [Bug 1755563] Re: dangling symlinks to loaded apparmor policy

[Zygmunt Krynicki]

** Description changed:

  On my artful system running 4.13.0-36-generic I noticed that there are
  dangling symlinks for "raw_data", "raw_sha1" and "raw_abi" files in the
  sysfs path containing loaded apparmor profiles.
  
  Sample of profiles that had dangling symlinks:
  
  
/sys/kernel/security/apparmor/policy/profiles/snap.core.hook.configure.35/raw_data
  
/sys/kernel/security/apparmor/policy/profiles/snap.core.hook.configure.35/raw_abi
  
/sys/kernel/security/apparmor/policy/profiles/snap.core.hook.configure.35/raw_sha1
  
  The following command can be used to find such files:
  
  find /sys/kernel/security/apparmor/policy/profiles -type l -exec sh -c
  "file -b {} | grep -q ^broken" \; -print
  
  It seems that neither xenial (4.4 kernel) nor bionic (4.15 kernel) is
  affected though I didn't perform an extensive investigation.
  
+ EDIT: This is inaccurate, bionic is affected as well. See below.
+ 
  I'm reporting this because according to the apaprmor developer it seems
  "racy" and should not happen.
  
   zyga-ubuntu: no, there shouldn't be a way to remove profiles 
wrong, there is the potential for a race of sorts because the symlink doesn't 
have the same hard reference, but that isn't something you should be seeing
   zyga-ubuntu: the raw_data file should not be going away as long 
as that profile directory exists
  
  It is likely that this problem occurs when snapd generates profiles for
  refreshed snaps or removes profiles for removed snaps but I was not able
  to determine that yet.
  
+ I updated my bionic system and noticed non-snap-related dangling symlink when 
the libreoffice package was updated:
+ /sys/kernel/security/apparmor/policy/profiles/libreoffice-senddoc.17/raw_data
+

  I dont' have this issue showing in dmesg when using 3.19 kernel,  only
  with later kernels.  Is it related to selecting encrypted home on
  install or something?

   I don't notice any issues with performance because of it or have any
  other error messages.  I am using default ubuntu xenial 16.04 with
  unity.

[Kernel-packages] [Bug 1753662] Re: [i40e] LACP bonding start up race conditions

[Nobuto Murata]

Oh wait,

> I built the next test kernel, up to the following commit:
> d38162e4b5c643733792f32be4ea107c831827b4
> 
> The test kernel can be downloaded from:
> http://kernel.ubuntu.com/~jsalisbury/lp1753662

d38162e4b5c643733792f32be4ea107c831827b4 looks in-between v4.12-rc3 and rc4 
which is expected.
https://github.com/torvalds/linux/commit/d38162e4b5c643733792f32be4ea107c831827b4

However, the link says "rc1".
http://kernel.ubuntu.com/~jsalisbury/lp1753662/linux-image-4.12.0-041200rc1-generic_4.12.0-041200rc1.201803131457_amd64.deb

Can you confirm that the 4.12.0-041200rc1 is the expected kernel test?

  [i40e] LACP bonding start up race conditions

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.

[Kernel-packages] [Bug 1753662] Re: [i40e] LACP bonding start up race conditions

[Nobuto Murata]

@Joseph,

Will do. Just as a possibility, I could build a kernel on the host if
that's helpful. Because the host is already reserved for this testing
and has hundreds of GBs of memory and many CPU cores. If you have a
pointer how to replicate your build process, that would be great.

  After upgrading to the Ubuntu EC2 AMI from 20180126 (specifically
  ami-79873901 in us-west-2) we have seen sssd hard locking c5 and m5
  EC2 instances after starting the service and CPU goes to 100%.

  We do not experience this issue with t2 or c4 instance types and we do
  not see this issue on any instance types using Ubuntu Cloud images
  from 20180109 or before. I have verified that this is kernel related
  as I booted an image that we created using the Ubuntu cloud image from
  20180109 which works fine on a c5. I then did a "apt update && apt
  install --only-upgrade linux-aws && systemctl disable sssd", rebooted
  the server, verified I was on the new kernel and started sssd with
  "systemctl start sssd" and the EC2 instance froze and Cloudwatch CPU
  usage for that instance went to 100%.

  I haven't been able to find much in the syslog, kern.log, journalctl
  logs, etc. The only thing I have been able to find is that when this
  happens I tend to see "^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@" in
  the syslog and sssd log files.  I have attached several log files and
  the output of a "apport-bug /usr/sbin/sssd". Let me know if you need
  anything else to help track this down.

  Thanks,
  Paul

Bug description:
  Long pressing a key will only repeat a few characters or won't repeat
  at all in the default 17.10 GNOME environment, it affects all keys
  including backspace and arrows.

  It isn't application specific, the problem is always there whether be
  it terminal or firefox.

  Setting the repeat delay to 0 will instantly trigger it, however it
  will still stop after a few characters.

  I freshly installed 17.10 on a Lenovo Ideapad 700, I haven't had the
  problem in 16.04 with GNOME 3.22.

  Edit: Happens in Xorg as well.

  "systemctl start sssd" and the EC2 instance froze and Cloudwatch CPU
  usage for that instance went to 100%.

  I haven't been able to find much in the syslog, kern.log, journalctl
  logs, etc. The only thing I have been able to find is that when this
  happens I tend to see "^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@" in
  the syslog and sssd log files.  I have attached several log files and
  the output of a "apport-bug /usr/sbin/sssd". Let me know if you need
  anything else to help track this down.

  Thanks,
  Paul

[Kernel-packages] [Bug 1753662] Re: [i40e] LACP bonding start up race conditions

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
d38162e4b5c643733792f32be4ea107c831827b4

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1753662

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

Title:
  [i40e] LACP bonding start up race conditions

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.

Bug description:
  After installing either 17.10 or 16.04 HWE to a minimal/command line
  environment, the login terminal displays a repeating string of ^@
  characters at a rate of approximately one per second. These are
  treated as actual input and prevent login as I am unable to type a
  username or password uninterrupted. Without an SSH server, the machine
  would be unusable. This does not happen under 16.04 using the standard
  non-HWE kernel.

  Hardware is a General Dynamics GD8200 laptop. BIOS has been reset and
  updated to latest version.

Bug description:
  Long pressing a key will only repeat a few characters or won't repeat
  at all in the default 17.10 GNOME environment, it affects all keys
  including backspace and arrows.

  It isn't application specific, the problem is always there whether be
  it terminal or firefox.

  Setting the repeat delay to 0 will instantly trigger it, however it
  will still stop after a few characters.

  I freshly installed 17.10 on a Lenovo Ideapad 700, I haven't had the
  problem in 16.04 with GNOME 3.22.

  Edit: Happens in Xorg as well.

[Colin Ian King]

ZRAM was not enabled for trusty 3.13, so I'll blacklist this as this
test is invalid for this kernel across the supported architectures.

  Hey there,

  We've had one of our LXD users report that setting the setgid bit
  inside a container using ZFS on Ubuntu 18.04 (zfs 0.7) is silently
  failing. This is not a LXD bug as the exact same operation works on
  other filesystems.

  There are more details available here:
  https://github.com/lxc/lxd/issues/4294

  Reproducer looks something like:

  ```

  This is particularly troubling because there are no errors returned to
  the user, so we now have containers that will have broken binaries and
  permissions applied to them with no visible way to detect the problem
  short of scanning the entire filesystem against a list of known
  permissions.

Title:
  Plymouth, Wayland not working under 4.15

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Bionic:
  Confirmed

Bug description:
  I just upgraded to bionic from artful and the kernel's graphics stack
  seems to be hosed. I can get text consoles, but neither plymouth nor
  Wayland GDM sessions work.

  X11 sessions do work however, e.g. by disabling Wayland for GDM3 in
  custom.conf or running startx from the console, however to get to that
  point you need to boot into a recovery session from the bootloader to
  avoid invoking the bootsplash, then proceed to boot normally from the
  recovery menu.

  If I boot into the 4.13 kernel I had leftover from artful, everything
  works fine.

  This is on a MacBookPro12,1 with an i7-5557U and Intel Iris 6100
  (Broadwell GT3) integrated GPU.

Bug description:
  Cavium ThunderX-based systems, such as the Cavium CRBs and Gigabyte
  implementations, have an ASPEED VGA controller that can be viewed
  remotely using a JAVA application exposed by the BMC. The kernel will
  use serial as the default console on this platform but, with the
  xenial GA (4.4) kernel, boot messages and a login prompt would also
  appear on the VGA display once the DRM stack was initialized during
  boot. You could also override the console default w/ console=tty0 if,
  for example, you wanted to do a d-i install over VGA instead of
  serial.

  This is no longer the case with later kernels. The significant
  difference is that CONFIG_FB_EFI  is now enabled, starting with this
  commit:

  UBUNTU: [Config] Enable various drivers for ARM platforms

  This driver detects an EFI framebuffer device, and uses that as the
  default VGA device instead of the ASPEED:

[Kernel-packages] [Bug 1755307] Re: Linux Kernel 4.4.0-116 does not work on ASUS-F200MA

[Joseph Salisbury]

Would it be possible for you to test the latest upstream stable kernel?
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the
latest v4.4 stable 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'.

If you are unable to test the mainline kernel, for example it will not boot, 
please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as 
"Confirmed".

Thanks in advance.

Bug description:
  Steps to Reproduce:
  - Ubuntu-32 16.04.1 on ASUS-F200MA
  - last Update in Dec 2017 with Linux Kernel 4.4.0-104
  - Update in Mar 2018 with Linux Kernel 4.4.0-116
  - Reboot

  Result:
  - Boot hangs with Ubuntu-Startscreen in wrong Resolution 800x600 instead 
1366x768.
  - The dots are moving, but nothing more happens.

  The Boot with Linux Kernel 4.4.0-104 still works and all hardware too, so I 
uninstalled 4.4.0--116 and manually installed Linux Kernel 4.4.0-108
  Result:
  - Boot successful with Ubuntu-Startscreen, but again in wrong Resolution 
800x600.
  - After login: wrong graphic resolution: 800x600, switch to 1366x768 not 
possible, no Sound, no network connection etc.

  Installing HWE Kernel with:
  - sudo apt-get install --install-recommends linux-generic-hwe-16.04 
xserver-xorg-hwe-16.04

  Result:
  - The system aigain works correctly.

  - I configured and ran same test over weekend and test ran good. KVM
  host did not crash in qlt_free_session_done call like before.

  - So the patch fixed the problem.

  ---Problem Description---
  Paul Mackerras has posted a fix to a Radix page fault handler bug in KVM:

  http://patchwork.ozlabs.org/patch/877033/
  " KVM: PPC: Book3S HV: Fix handling of large pages in radix page fault 
handler "

  This is critical for P9 KVM performance. Using an open source database 
workload, we saw an 11% throughput improvement with this patch when the guest 
was backed w/ 2MB hugepages. Without this patch, hugepage backing does not help 
performance compared to base page size.

[Kernel-packages] [Bug 1746806] Re: sssd appears to crash AWS c5 and m5 instances, cause 100% CPU

[David JM Emmett]

This issue is not limited to EC2. I'm running artful on a Dell Optiplex
5040 with an i5-6500 CPU (which is Skylake); I've just installed sssd
and hit the full system freeze. Even REISUB didn't work!

  After upgrading to the Ubuntu EC2 AMI from 20180126 (specifically
  ami-79873901 in us-west-2) we have seen sssd hard locking c5 and m5
  EC2 instances after starting the service and CPU goes to 100%.

  We do not experience this issue with t2 or c4 instance types and we do
  not see this issue on any instance types using Ubuntu Cloud images
  from 20180109 or before. I have verified that this is kernel related
  as I booted an image that we created using the Ubuntu cloud image from
  20180109 which works fine on a c5. I then did a "apt update && apt
  install --only-upgrade linux-aws && systemctl disable sssd", rebooted
  the server, verified I was on the new kernel and started sssd with
  "systemctl start sssd" and the EC2 instance froze and Cloudwatch CPU
  usage for that instance went to 100%.

  I haven't been able to find much in the syslog, kern.log, journalctl
  logs, etc. The only thing I have been able to find is that when this
  happens I tend to see "^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@" in
  the syslog and sssd log files.  I have attached several log files and
  the output of a "apport-bug /usr/sbin/sssd". Let me know if you need
  anything else to help track this down.

  Thanks,
  Paul

Title:
  Servers going OOM after updating kernel from 4.10 to 4.13

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Artful:
  Fix Committed

Bug description:
  == SRU Justification ==
  We are seeing this on multiple servers after upgrading from previous 4.10 
series HWE kernels to the new 4.13 HWE series. With the new kernel, free memory 
is continously decreasing at a high rate and the servers start swapping and 
finally OOMing services within days. With the 4.10 kernel, decrease of free 
memory is slower and stabilizes after a while.

  Latest kernel tested is linux-image-4.13.0-32-generic but the issue
  also affects older kernels from that series, tested back to linux-
  image-4.13.0-19-generic. No issue with linux-image-4.10.0-42-generic.

  The servers are running as OpenStack controller nodes using either
  Ocata or Pike UCA plus ceph. See attached graph for the memory
  behaviour.

  == Fix ==
  2b9478ffc550("i40e: Fix memory leak related filter programming status")
  62b4c6694dfd("i40e: Add programming descriptors to cleaned_count")

  == Regression Potential ==
  Low.  Limited to i40e and fix existing regression.

  == Test Case ==
  A test kernel was built with these patches and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.
