Title:
  Kernel trace with xenial 4.4  (4.4.0-108.131, Candidate kernels for
  PTI fix)

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Fix Released

Bug description:
  ### HOW TO BOOT INTO PREVIOUS KERNEL IF UNABLE TO BOOT ###

  If you hit this bug and are unable to boot, you can boot back into the
  last working kernel.  To do that, select that version(Probably
  4.4.0-104) from the GRUB menu.

  The GRUB menu can be accessed by holding the 'Shift' key after powering on 
the system(Some systems require the 'ESC' key to be held instead of Shift).  
Detailed information about GRUB can be found here:
  https://help.ubuntu.com/community/Grub2



  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

  Kernel trace message as:

[Kernel-packages] [Bug 1741934] Re: Kernel trace with xenial 4.4 (4.4.0-108.131, Candidate kernels for PTI fix)

2018-01-10 Thread Marat Khalili

On 14.04 with LTS Enablement Stack I can confirm that 4.4.0-108 was
broken in the described way (trap on kfree) and 4.4.0-109 works.

  Kernel trace with xenial 4.4  (4.4.0-108.131, Candidate kernels for
  PTI fix)

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:

Bug description:
  ### HOW TO BOOT INTO PREVIOUS KERNEL IF UNABLE TO BOOT ###

  If you hit this bug and are unable to boot, you can boot back into the
  last working kernel.  To do that, select that version(Probably
  4.4.0-104) from the GRUB menu.

  The GRUB menu can be accessed by holding the 'Shift' key after powering on 
the system(Some systems require the 'ESC' key to be held instead of Shift).  
Detailed information about GRUB can be found here:
  https://help.ubuntu.com/community/Grub2



  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

[Kernel-packages] [Bug 1741934] Re: Kernel trace with xenial 4.4 (4.4.0-108.131, Candidate kernels for PTI fix)

2018-01-10 Thread Joseph Salisbury

** Description changed:

+ ### HOW TO BOOT INTO PREVIOUS KERNEL IF UNABLE TO BOOT ###
+ 
+ If you hit this bug and are unable to boot, you can boot back into the
+ last working kernel.  To do that, select that version(Probably
+ 4.4.0-104) from the GRUB menu.
+ 
+ The GRUB menu can be accessed by holding the 'Shift' key after powering on 
the system(Some systems require the 'ESC' key to be held instead of Shift).  
Detailed information about GRUB can be found here:
+ https://help.ubuntu.com/community/Grub2
+ 
+

  [Description]
  
  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same kernel
  trace shown in many different pre-installed Ubuntu images of different
  platform.
  
  So far these platform are known to reproduce this issue:
  
  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)
  
  [Steps to Reproduce]
  
  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.
  
  [Expected Result]
  
  No kernel trace message.
  
  [Actual Result]
  
  Kernel trace message as:

You can try to boot the last working kernel and then pull the updates
and reboot.

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

I had default the nouveau driver driving the nvidia card. Seems there
were some problems with the Nvidia driver:
https://www.reddit.com/r/linuxquestions/comments/7pbro7/ubuntu_meltdown_patch_breaks_system_wont_boot/

However 4.4.0-109-generic fixed this.

Thanks a lot to Ubuntu for their quick fix and to Norbert for letting us
know here.

[Kernel-packages] [Bug 1741934] Re: Kernel trace with xenial 4.4 (4.4.0-108.131, Candidate kernels for PTI fix)

2018-01-10 Thread Norbert

With latest 4.4.0-109-generic
1. My laptop with i7-3537U CPU - works normally.
2. My i7-4790 machine - works normally.
3. My i7 Q740 laptop - works normally.

For those who affected:
1. Remove 108 kernel with
sudo apt-get purge linux-headers-4.4.0-108 linux-headers-4.4.0-108-generic 
linux-image-4.4.0-108-generic linux-image-extra-4.4.0-108-generic 
linux-tools-4.4.0-108 linux-tools-4.4.0-108-generic
sudo apt-get autoremove
2. Wait for 109 kernel to appear on your mirror or temporarily switch to "Main 
server" (http://archive.ubuntu.com/ubuntu) and get it from here.

  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

[Kernel-packages] [Bug 1741934] Re: Kernel trace with xenial 4.4 (4.4.0-108.131, Candidate kernels for PTI fix)

2018-01-10 Thread P Gopal Krishnan

Hi, I am not an expert and have basic functional operating knowledge of
Ubuntu. I am using a Dell Latitude 5480 and Ubuntu 16.04 LTS. I did a
software update this morning and since then I am unable to shut down and
get the error starting with -

kernel BUG at /build/linux-J4_1pC/linux-4.4.0/mm/slub.c:3627!

Is there a fix that you can suggest which I can run? Thanks

Bug description:
  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

Thank you @jsalisbury. Sorry for my misunderstanding with the status
label.

I will keep an eye out for when the update arrives and I will just avoid
rebooting the server until then.

[Kernel-packages] [Bug 1741934] Re: Kernel trace with xenial 4.4 (4.4.0-108.131, Candidate kernels for PTI fix)

2018-01-09 Thread Joseph Salisbury

@Leith, it will not be available in -updates until the status changes to
"Fix Released".  This should happen soon.

In the mean time you can install the kernel I posted in comment #24.
You would need to install the linux-image and linux-image-extra .deb
packages.

  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

@jsalisbury are you sure the fixed version has been uploaded? Still not
getting any new kernel to replace the currently installed buggy one via
apt update

2018-01-09 Thread Leith Bade

What exact package version do I need for this fix?

My system auto-updated to the buggy kernel and crashed in the same
location as the original reporter.

For reference the system:
Motherboard: Asus P9D-I
BIOS: Version 1801
CPU: Intel(R) Xeon(R) CPU E3-1220 v3 @ 3.10GHz

  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

  Kernel trace message as:

  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel trace shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel trace message.

  [Actual Result]

  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same kernel
- panic shown in many different pre-installed Ubuntu images of different
+ trace shown in many different pre-installed Ubuntu images of different
  platform.
  
  So far these platform are known to reproduce this issue:
