  [Regression] Colour banding appears on Lenovo B50-80 integrated
  display

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  The problem affects the integrated display on a Lenovo B50-80
  notebook.

  Colour banding is visible everywhere on the system, as dithering seems
  not to be enabled on this 6bpp display. This issue was not present on
  non-HWE Ubuntu 16.04, and it showed up after I upgraded to Ubuntu
  18.04. There was already a very similar bug #1749420 that had a fix
  released, however, because the make and model of an LCD screen in that
  case was different, the quirk added to the kernel did not address the
  problem that affects my machine. The cause of this issue is probably
  the same, since I have checked that pre-4.8.0-rc2 kernels handled
  dithering correctly, and 4.8.0-rc2 and later kernels already had the
  bug described. I believe that adding quirk for an another type of
  display may fix the problem.

  I attached the results of running
  sudo get-edid | parse-edid in a file named edid.txt
  and
  sudo get-edid | edid-decode in a file named edid-decoded.txt.

Bug description:
  Colour bandind is visible everywhere in the system, and it appeared
  after I had my integrated monitor replaced. I believe it's not a
  hardware problem, since booting with 'nomodeset' works as expected.

  There were already two similar bugs,
  https://bugs.launchpad.net/bugs/1749420 and
  https://bugs.launchpad.net/bugs/1788308, but the fixes provided for
  those bugs did not work for my specific monitor.

  I'm running Ubuntu 18.04 with kernel linux-image-4.15.0-34-generic,
  installing linux-image-4.18.8 with UKUU didn't help.

  I attached the results of running
  sudo get-edid | parse-edid in a file named edid.txt
  sudo get-edid | edid-decode in a file named edid-decoded.txt
  cat /proc/version_signature in version.log

  4.12.0-11-generic - crashing in infrastructure on i386 openvswitch
  tests

Bug description:
  Hi,
  this seems to me to be a kernel crash of some sorts.
  Somewhat in the spirit of older bugs:
  - bug 1630940
  - bug 1630578

  Xnox asked me to look into a hang on openvswitch dep8 tests.
  What I found initially was in the log just
"ERROR: Removing temporary files on testbed timed out"
  That message brought me to the two bugs above.

  But in there I read that this was the infra running dep8 crashing.
  So for a better bug report I tried to reproduce locally and that actually 
seems to work very reliable.

  To reproduce do:
  $ autopkgtest-buildvm-ubuntu-cloud -a i386 -r artful -s 10G
  $ pull-lp-source openvswitch
  $ autopkgtest --apt-upgrade --shell --no-built-binaries 
openvswitch_2.8.0~git20170809.7aa47a19d-0ubuntu1.dsc -- qemu 
~/work/autopkgtest-artful-i386.img
  # This guest currently will crash after a while of testing

  
  But with that running you can attach to the console and monitor of that guest.
  For example:
  $ sudo nc -U /tmp/autopkgtest-virt-qemu.*/ttyS0

  That gave me a crash on the hang which kind of matches the older bugs, here 
the console:

Bug description:
  == SRU Justification ==

  Commit 120645513f55 ("openvswitch: Add eventmask support to CT
  action.") introduced a regression on i386. Simply running the
  following commands in a loop will trigger a crash rather quickly:

  ovs-vsctl add-br test
  ovs-vsctl del-br test

  == Fix ==

  Disable the logic introduced by the above commit on i386.

  == Regression Potential ==

  Low, the above commit introduced a new feature. Per upstream, the
  result of not having this feature results in higher CPU usage and
  potential buffering issues in user space.

  == Test Case ==

  See SRU justification above.

@james-page, the fix has been sent to the Ubuntu kernel mailing list
[1], so it's scheduled for the next SRU cycle (assuming it gets two
ACKs).

Bug description:
  SRU Justification:

  [Impact]

   * Flow action buffer can be incorrectly resized to contain the newly
  added action entries: the buffer is always resized multiplying the
  previous size by 2, but this might be not enough if the requested size
  is bigger than previous_size*2, causing a buffer overflow

   * The fix correctly resizes the buffer to prevent the buffer overflow

   * Despite the subject this bug can be triggered potentially on any
  architecture, but it is very likely to happen on i386 running the
  following test case

  [Test Case]

   * run this openvswitch test case:
  https://launchpadlibrarian.net/416589265/lp1262692

  [Fix]

   * Instead of resizing the buffer by a factor of 2, use
  max(current_size * 2, current_size + requested_size)

  [Regression Potential]

  [Original bug report]

  This issue was found after leaving a SUT to run overnight (was testing
  the ubuntu_cts_kernel test 13 hours ago before this happens). Can't
  tell if this is a regression, as I haven't find a way to reproduce it.
  But I do see similar reports on the Internet [1]

  After checking the systemd service timers, it looks like this is
  caused by the logrotate.service:

[Kernel-packages] [Bug 1788098] Re: Avoid migration issues with aligned 2MB THB

[Juerg Haefliger]

Stefan NACK'ed the series. For some unknown reason that email did make
it into the archive so here is ist content:

> Since commit fb1522e099f0 ("KVM: update to new mmu_notifier semantic
> v2", 2017-08-31), the MMU notifier code in KVM no longer calls the
> kvm_unmap_hva callback.  This removes the PPC implementations of
> kvm_unmap_hva().  

This is not really the way SRUs should be done. We cannot remove support for
interfaces after release. Also the amount of change as a requisite should be
kept as minimal as possible. This just feels like too many changes without a
strong argument on why this must be done that way.

  --- Comment From jhop...@us.ibm.com 2018-08-20 17:12 EDT---

  Hi, in some environments it was observed that this qemu patch to
  enable THP made it more likely to hit guest migration issues, however
  the following kernel patch resolves those migration issues:

  
https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=c066fafc595eef5ae3c83ae3a8305956b8c3ef15
  KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()

  Once merged upstream, it would be good to include that change as well
  to avoid potential migration problems. Should I open a new bug for
  that or is it better to track here?

  Note Paelzer: I have not seen related migration issues myself, but it
  seems reasonable and confirmed by IBM.

   * Flow action buffer can be incorrectly resized to contain the newly

   * Instead of resizing the buffer by a factor of 2, use
  max(current_size * 2, current_size + requested_size)

  [Regression Potential]

[Kernel-packages] [Bug 1788098] Re: Avoid migration issues with aligned 2MB THB

[Juerg Haefliger]

Leonardo, since you seem to have a reliable reproducer now, could you
give this test kernel [1] a try? It just contains commit c066fafc595e
("KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()") and
is basically what Joe gave you (comment #5) but at that time you weren't
able to reproduce the issue.

  FYI: This blocks bug 1781526 - once this one here is resolved we can

  --- Comment From jhop...@us.ibm.com 2018-08-20 17:12 EDT---

  Hi, in some environments it was observed that this qemu patch to
  enable THP made it more likely to hit guest migration issues, however
  the following kernel patch resolves those migration issues:

  
https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=c066fafc595eef5ae3c83ae3a8305956b8c3ef15
  KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()

  Once merged upstream, it would be good to include that change as well
  to avoid potential migration problems. Should I open a new bug for
  that or is it better to track here?

  Note Paelzer: I have not seen related migration issues myself, but it
  seems reasonable and confirmed by IBM.

[Kernel-packages] [Bug 1831899] Re: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space

[Juerg Haefliger]

I started to take a look at the dumps and noticed that there are faults
in libc-2.17 (and not 2.23 as mentioned in the bug description). What
are you running in those docker images? Can you share some details about
what the machine was doing when it died?

  == Fix ==

  Backport the following 3 commits:
   * scsi: iscsi: target: Fix conn_ops double free
   * scsi: iscsi: target: Set conn->sess to NULL when
     iscsi_login_set_conn_values fails
   * iscsi target: fix session creation failure handling

  == Regression Potential ==

  Low. Clean cherry-picks that modify a very isolated area.

  == Test ==

  Setup an iSCSI target using the scsi_target_user module and
  tcmu_runner. Setup an initiator to connect to the target and do IOs.
  Reboot the target. When the target comes back, the kernel falls over
  when the initiator tries to re-connect.

[Kernel-packages] [Bug 1831899] Re: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space

[Juerg Haefliger]

Is this easily reproducible? Can you retry with the latest released
kernel 4.15.0-58.64? I haven't been able to reproduce the problem
locally so far. It would help if you could share the container and
workload, if that's possible at all. I'm still looking through the
dumpfiles but haven't made much progress yet towards finding the root
cause.

Bug description:
  [Impact]

   * This belongs to the overall context of spectre mitigations and even 
 more the try to minimize the related performance impacts.
 On ppc64el there is a new chip revision (DD 2.3) which provides
 a facility that helps to better mitigate some of this.

   * Backport the patches that will make the feature (if supported by the 
 HW) will pass the capability to the guest - to allow guests that 
 support the improved mitigation to use it.

  [Test Case]

   * Start guests with and without this capability
 * Check if the capability is guest visible as intented
 * Check if there are any issues on pre DD2.3 HW
   * Test migrations (IBM outlined the intented paths that will work 
 below)
   * The problem with the above (and also the reasons I didn't add a list 
 of commands this time) is that it needs special HW (mentioned DD2.3 
 revision) of the chips which aren't available to us right now.
 Due to that testing / verification of this on all releases is on IBM

  [Regression Potential]

   * Adding new capabilities usually works fine, there are three common 
 pitfalls which here are the regression potential.
 - (severe) the code would announce a capability that isn't really 
   available. The guest tries to use it and crashes
 - (medium) several migration paths especially from systems with the 
   new cap to older (un-updated systems) will fail. But that applies 
   to any "from machine with Feature to machine without that feature" 
   and isn't really a new regression. As outlined by IBM below they 
   even tried to make it somewhat compatible (by being a new value in 
   an existing cap)
 - (low) the guest will see new caps and or facilities. A really odd
   guest could stumble due to that (would actually be a guest bug 
   then)
Overall all of the above was considered by IBM when developing this 
and should be ok. For archive wide SRU considerations, this has NO 
effect on non ppc64el.

  [Other Info]
   
   * n/a

  ---

  Power9 DD 2.3  CPUs  running updated firmware will use a new Spectre
  v2 mitigation. The new mitigation improves performance of branch heavy
  workloads, but also requires kernel support in order to be fully
  secure.

  Without the kernel support there is a risk of a Spectre v2 attack
  across a process context switch, though it has not been demonstrated
  in practice.

  QEMU portion - platform definition needs to account for this new
  mitigation action.. so attribute for this needs to be added.

  In terms of support for virtualisation there are 2 sides, kvm and qemu
  support. Patch list for each,

  KVM:
  2b57ecd0208f KVM: PPC: Book3S: Add count cache flush parameters to 
kvmppc_get_cpu_char()
  This is part of LP1822870 already.

  QEMU:
  8ff43ee404 target/ppc/spapr: Add SPAPR_CAP_CCF_ASSIST
  399b2896d4 target/ppc/spapr: Add workaround option to SPAPR_CAP_IBS

  The KVM side is upstream as of v5.1-rc1.
  The QEMU side is upstream as of v4.0.0-rc0.

  In terms of migration the state is as follows.

  In order to specify to the guest to use the count cache flush
  workaround we use the spapr-cap cap-ibs (indirect branch speculation)
  with the value workaround. Previously the only valid values were
  broken, fixed-ibs (indirect branch serialisation) and fixed-ccd (count
  cache disabled). And add a new cap cap-ccf-assist (count cache flush
  assist) to specify the availability of the hardware assisted flush
  variant.

  Note the the way spapr caps work you can migrate to a host that supports a 
higher value, but not to one which doesn't support the current value (i.e. only 
supports lower values). Where for cap-ibs these are defined as:
  0 - Broken
  1 - Workaround
  2 - fixed-ibs
  3 - fixed-ccd

  So the following migrations would be valid for example:
  broken -> fixed-ccd, broken -> workaround, workaround -> fixed-ccd

  While the following would be invalid:
  fixed-ccd -> work

[Kernel-packages] [Bug 1828350] [NEW] Add support for Intel I210 NIC

[Juerg Haefliger]

Private bug reported:

== SRU Justification ==

The Precise 3.2 kernel doesn't support the Intel I210 NIC. It's a fairly
old and common NIC which is also in my test system. It would help with
testing Precise if that NIC was supported.

== Fix ==

Backport the following 3 commits wich add I210 support:
  - igb: Fix incorrect RAR address entries for i210/i211 device.
  - igb: Add Support for new i210/i211 devices.
  - igb: Add function and pointers for 82580 low power state settings.

== Regression Potential ==

Low. This is mostly new code that is only exercised when an I210 NIC is
present. There is some shuffling around and the introduction of low
power settings handling for other NIC types as well so there is some
risk. But it's isolated to the igb NIC driver.

== Test Case ==

Boot a patched kernel and verify the NIC is recognized and the network
comes up.

[Kernel-packages] [Bug 1788098] Re: Avoid migration issues with aligned 2MB THB

[Juerg Haefliger]

Leonardo, can you elaborate on the 'other possible issues'? We're
hesitant to pull 18 patches into a stable kernel under the assumption
that they *might* fix some *potential* issues, without clear evidence.
If you can test the single-patch kernel and report back that there are
still issues then that's a much stronger case for the other patches.

Commit 'KVM: PPC: Book3S HV: Avoid crash from THP collapse during radix
page fault' that you're asking for requires all these additional
backports to apply cleanly. Which makes me wonder if we're not actually
introducing a problem with these backports just to fix it again later.
Not saying that's the case, just wondering...

Also, the following seem to be totally unrelated and unnecessary:
  - KVM: PPC: Remove unused kvm_unmap_hva callback
  - powerpc/mm/radix: Remove unused code

While looking through the patches I also noticed that the following is the 
second patch of a series of 11 but it's the only one from the series that 
you're backporting.
  - powerpc/kvm: Switch kvm pmd allocator to custom allocator
Its commit message mentions subsequent patches of that series so I'm wondering 
why we need/want only this single patch??

Remember that we have to support this kernel for years and years to come
so we only want to backport the absolute necessary.

Lastly and FYI, the following is the minimal subset of your patches that all 
cherry-pick cleanly:
  - KVM: PPC: Book3S HV: Avoid crash from THP collapse during radix page fault
  - KVM: PPC: Book3S HV: Don't use compound_order to determine host mapping size
  - KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()
  - KVM: PPC: Book3S HV: radix: Refine IO region partition scope attributes
  - KVM: PPC: Book3S HV: Use __gfn_to_pfn_memslot() in page fault handler
  - KVM: PPC: Book3S HV: Handle 1GB pages in radix page fault handler
  - KVM: PPC: Book3S HV: Streamline setting of reference and change bits
  - KVM: PPC: Book3S HV: Radix page fault handler optimizations

Please provide some context why we need all the above (and potentially
more).

  --- Comment From jhop...@us.ibm.com 2018-08-20 17:12 EDT---

  Hi, in some environments it was observed that this qemu patch to
  enable THP made it more likely to hit guest migration issues, however
  the following kernel patch resolves those migration issues:

  
https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=c066fafc595eef5ae3c83ae3a8305956b8c3ef15
  KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()

  Once merged upstream, it would be good to include that change as well
  to avoid potential migration problems. Should I open a new bug for
  that or is it better to track here?

  Note Paelzer: I have not seen related migration issues myself, but it
  seems reasonable and confirmed by IBM.

[Kernel-packages] [Bug 1828632] Re: bionic i386 kernel crashes in memory pressure situations

[Juerg Haefliger]

Thanks Steve, but I'm still not able to reproduce the kernel crash. If I
start netbeans, the current session is killed and I'm thrown back to the
login screen. If I do this multiple times the VM eventually simply dies.
But no kernel crash.

kernel: 4.15.0-49-generic
netbeans: 10.0-3~18.04.1ubuntu1
openjdk-11-jre: 11.0.3+7-1ubuntu2~18.04.1

qemu-system-x86_64: /build/qemu-VBsewI/qemu-3.1+dfsg/hw/display/qxl.c:1230: 
qxl_check_state: Assertion `!spice_display_running || 
SPICE_RING_IS_EMPTY(&ram->cmd_ring)' failed.
2019-05-14 07:32:36.996+: shutting down, reason=crashed

I'm on a Disco host, are you running on Bionic?

Bug description:
  The linux-image-4.15.0-49-generic (currently in bionic-proposed) can
  be made to crash in a kvm guest with memory pressure. The reproducer
  used is to attempt to run netbeans with openjdk-8-jre installed as the
  only jvm. It will fail to run, and when it fails, it also causes
  gnome-shell to crash. After 3 to 5 repeats of this, the kernel will
  crash with the following oops in dmesg:

  = Impact =

  Network loss and traffic loss problems experienced by customer with i40e 
2.1.14-k in Xenial HWE Kernel 4.15
  The traffic issues were reported from our customer deployments and we had 
Intel helping us with the troubleshooting of the problem.

  = Fix =

  Intel recommends and customer requests application of the following
  commit e78d9a39fd06109022d11c8ca444cfcec2abb290 (upstream Linus tree)

  = Testcase =

  The issue could only be seen in customer environment. Regression
  testing only would be possible.

  = Regression Potential =

  Change is limited to a specific driver, testing should show if there
  is any negative impact.

Bug description:
  == SRU Justification ==
  Upstream's Spectre v1 mitigation prevents speculation on a user controlled 
pointer. This part of the Spectre v1 patchset was never backported to 4.4 (for 
unknown reasons) so Xenial/Trusty/Precise are lacking it as well. All the other 
stable upstream kernels include it, so add it to our older kernels.

  == Fix ==
  Backport the following patches:
  x86/uaccess: Use __uaccess_begin_nospec() and uaccess_try_nospec
  x86/usercopy: Replace open coded stac/clac with __uaccess_{begin, end}
  x86: Introduce __uaccess_begin_nospec() and uaccess_try_nospec

  == Regression Potential ==
  Low. Patches have been in upstream (and other distro kernels) for quite a 
while now and the changes only introduce a barrier on copy_from_user operations.

  == Test Case ==
  TBD.

Bug description:
  Xenial/Trusty/Precise are currently lacking full support of upstream's
  Spectre v1 mitigation. Add the missing patches and merge them with
  Ubuntu's current implementation.

  == SRU Justification ==
  Ubuntu's Spectre v1 mitigation is based on the original embargoed patchset 
which introduced a barrier macro to prevent speculation beyond array boundaries 
for user controlled indices. What eventually landed in upstream is slightly 
different and uses a barrier macro in combination with a masking solution (plus 
syscall table and user pointer sanitation). During the updates to newer stable 
upstream versions, all those patches were skipped. After reviewing them, we 
want to bring them back and merge them with the current implementation which 
brings us back in sync with upstream stable.

  == Fix ==
  Add all the missing Spectre v1 patches from upstream stable 4.4.118 to 
4.4.131. Where appropriate, replace Ubuntu's additional barriers with the 
masking macro.

  == Regression Potential ==
  Low. The patches have been in upstream for quite a while now and we keep the 
speculation barriers that are currently in Ubuntu but not in upstream.

  == Test Case ==
  TBD.

Bug description:
  == SRU Justification ==

  Ubuntu kernels contain Meltdown and Spectre mitigations that are
  largely based on embargoed patches but what eventually landed in
  upstream is different in some places. We should clean up the different
  kernels to bring them closer in line with upstream.

  == Fix ==

  Add missing upstream patches.

  == Regression Potential ==

  Medium. The patches have been in upstream for quite a while now and
  are baked in but some of the backporting is not completely trivial and
  without risk.

  == Test Case ==

  TBD.

[Kernel-packages] [Bug 1830176] [NEW] Xenial update: 4.4.180 upstream stable release

[Juerg Haefliger]

Public bug reported:


SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree or
   a minimally backported form of that patch. The following upstream
   stable patches should be included in the Ubuntu kernel:

   4.4.180 upstream stable release

Bug description:
  
  SRU Justification

  Impact:
 The upstream process for stable tree updates is quite similar
 in scope to the Ubuntu SRU process, e.g., each patch has to
 demonstrably fix a bug, and each patch is vetted by upstream
 by originating either directly from a mainline/stable Linux tree or
 a minimally backported form of that patch. The following upstream
 stable patches should be included in the Ubuntu kernel:

 4.4.180 upstream stable release
 from git://git.kernel.org/

  
  Linux 4.4.180
  powerpc/lib: fix book3s/32 boot failure due to code patching
  powerpc/booke64: set RI in default MSR
  drivers/virt/fsl_hypervisor.c: prevent integer overflow in ioctl
  drivers/virt/fsl_hypervisor.c: dereferencing error pointers in ioctl
  bonding: fix arp_validate toggling in active-backup mode
  ipv4: Fix raw socket lookup for local traffic
  vrf: sit mtu should not be updated when vrf netdev is the link
  vlan: disable SIOCSHWTSTAMP in container
  packet: Fix error path in packet_init
  net: ucc_geth - fix Oops when changing number of buffers in the ring
  bridge: Fix error path for kobject_init_and_add()

already.

== Fix ==

Backport the relevant commits.

== Test Case ==

TBD.

[Kernel-packages] [Bug 1822760] [NEW] Bionic: Sync to Xenial (Spectre)

[Juerg Haefliger]

Public bug reported:

== SRU Justification ==

There are a couple of Spectre related commits in Xenial that never
landed in Bionic. Fix that to prevent a regression when upgrading from
Xenial to Bionic.

== Regression Potential ==

Low. These are not very intrusive commits that have been in upstream for
quite a while.

== Fix ==

Backport the relevant commits from upstream.

== Test Case ==

TBD.

[Kernel-packages] [Bug 1711056] Re: Backport more recent Broadcom bnxt_en driver

[Juerg Haefliger]

** Changed in: linux (Ubuntu)
   Status: Incomplete => Invalid

You received this bug notification because you are a member of Kernel

Title:
  Backport more recent Broadcom bnxt_en driver

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

Bug description:
  [Impact]

  The current Xenial bnxt_en driver only supports a limited (old) set of
  Broadcom NICs. We want to support newer NICs in Xenial without adding
  risk for existing users.

  The plan is to provide a separate driver called bnxt_en_bpo which is a
  backported driver from Broadcom. This driver will be modified to only
  support the new NICs that the current kernel driver does not support
  so that they both can co-exist.

  In other words, NICs that used to be supported by Xenial will still be
  managed by the current (unmodified) bnxt_en driver. Newer NICs will be
  managed by the new bnxt_en_bpo driver.

  [Test Case]

  Due to the unavailability of Broadcom HW, the only test that was run
  was to manually load both the bnxt_en and bnxt_en_bpo module to ensure
  that they can co-exist.

  [Regression Potential]

  There should be no regression potential, since the current driver is
  not modified and the new driver only loads for NICs that are not
  handled by the current driver.

Bug description:
  == SRU Justification ==
  Upstream's Spectre v1 mitigation prevents speculation on a user controlled 
pointer. This part of the Spectre v1 patchset was never backported to 4.4 (for 
unknown reasons) so Xenial/Trusty/Precise are lacking it as well. All the other 
stable upstream kernels include it, so add it to our older kernels.

  == Fix ==
  Backport the following patches:
  x86/uaccess: Use __uaccess_begin_nospec() and uaccess_try_nospec
  x86/usercopy: Replace open coded stac/clac with __uaccess_{begin, end}
  x86: Introduce __uaccess_begin_nospec() and uaccess_try_nospec

  == Regression Potential ==
  Low. Patches have been in upstream (and other distro kernels) for quite a 
while now and the changes only introduce a barrier on copy_from_user operations.

  == Test Case ==
  TBD.

  Fix Released

Bug description:
  == SRU Justification ==

  Booting Trusty with kernel 3.13.0-156-generic on a fairly new Intel
  box with a i40e NIC results in no network. The 3.13 i40e driver
  doesn't support the following HW:

  3d:00.0 Ethernet controller: Intel Corporation Device 37d2 (rev 02)
  Subsystem: Intel Corporation Device 35ce
  Flags: bus master, fast devsel, latency 0, IRQ 37
  Memory at ac00 (64-bit, prefetchable) [size=16M]
  Memory at ad808000 (64-bit, prefetchable) [size=32K]
  Expansion ROM at ad98 [disabled] [size=512K]
  Capabilities: 

  Base Board Information
  Manufacturer: Intel Corporation
  Product Name: S2600WFT

  This is a Canonical test system and having functional networking with
  a Trusty kernel would help with - well - testing :-)

  == Fix ==

  Add a backport driver in addition to the in-tree driver that supports
  newer versions of the i40e NIC.

  == Regression Potential ==

  Low. The new driver will only load for NICs that are not supported by
  the current in-tree driver.

  == Test Case ==

  Boot a patched kernel and verify the NIC is recognized and the network
  comes up.

 a minimally backported form of that patch. The following upstream

Bug description:
  
  SRU Justification

  Impact:
 The upstream process for stable tree updates is quite similar
 in scope to the Ubuntu SRU process, e.g., each patch has to
 demonstrably fix a bug, and each patch is vetted by upstream
 by originating either directly from a mainline/stable Linux tree or
 a minimally backported form of that patch. The following upstream
 stable patches should be included in the Ubuntu kernel:

Title:
  Segmentation fault in ldt_gdt_64

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Trusty:
  Fix Released

Bug description:
  == SRU Justification ==
  The ldt_gdt_64 x86 selftest segfaults with the currently released Trusty 3.13 
kernel. The commit that introduced the segfault is aeb315d60afe ("x86/ldt: Make 
modify_ldt synchronous").

  == Fix ==
  Upstream commit 8ff5bd2e1e27 ("x86/signal/64: Fix SS if needed when 
delivering a 64-bit signal"). This commit was found by doing a reverse git 
bisect of the upstream kernel (i.e., when did the test stop segfaulting).
  The backport of the commit is a simple context adjustment. The second commit 
is a pre-requisite which simply renames some defines (no functional changes).

  == Regression Potential ==
  Low. The commit is very small and isolated and the code path is only executed 
in special circumstances (and for x86 only). I built a test kernel and ran the 
whole set of x86 selftests and perf NMI test for several hours to verify 
stability.

  == Test Case ==
  Run the ldt_gdt_64 x86 selftets from a current upstream kernel source. The 
test segfaults consistently.

  Original bug description:

  Trusty 3.13 segfaults when running ldt_gdt_64 from the kernel's x86
  selftests.

  git bisect revealed that the following commit introduced the issue:

  commit aeb315d60afee129d32558f4a4b356eec2e7da7b
  Author: Andy Lutomirski 
  Date:   Thu Jul 30 14:31:32 2015 -0700

  x86/ldt: Make modify_ldt synchronous

  CVE-2017-5754

  commit 37868fe113ff2ba814b3b4eb12df214df555f8dc upstream.

  modify_ldt() has questionable locking and does not synchronize
  threads.  Improve it: redesign the locking and synchronize all
  threads' LDTs using an IPI on all modifications.

  This will dramatically slow down modify_ldt in multithreaded
  programs, but there shouldn't be any multithreaded programs that
  care about modify_ldt's performance in the first place.

  This fixes some fallout from the CVE-2015-5157 fixes.

Bug description:
  I'm running a Windows7 guest in KVM via libvirt/virt-manager on a
  Oneiric desktop 64-bit. Every once in a while (2-3 times a week,
  sometimes daily) the CPU usage goes berserk and the host becomes very
  unresponsive and unusable. This also happened once with a Breezy guest
  so it's not strictly a Windows issue. I'm just seeing it more often
  with Windows because that's what I run daily.

  More information attached, let me know what other info I should collect, the 
next time the machine is in that state.

Bug description:
  Xenial/Trusty/Precise are currently lacking full support of upstream's
  Spectre v1 mitigation. Add the missing patches and merge them with
  Ubuntu's current implementation.

  == SRU Justification ==
  Ubuntu's Spectre v1 mitigation is based on the original embargoed patchset 
which introduced a barrier macro to prevent speculation beyond array boundaries 
for user controlled indices. What eventually landed in upstream is slightly 
different and uses a barrier macro in combination with a masking solution (plus 
syscall table and user pointer sanitation). During the updates to newer stable 
upstream versions, all those patches were skipped. After reviewing them, we 
want to bring them back and merge them with the current implementation which 
brings us back in sync with upstream stable.

  == Fix ==
  Add all the missing Spectre v1 patches from upstream stable 4.4.118 to 
4.4.131. Where appropriate, replace Ubuntu's additional barriers with the 
masking macro.

  == Regression Potential ==
  Low. The patches have been in upstream for quite a while now and we keep the 
speculation barriers that are currently in Ubuntu but not in upstream.

  == Test Case ==
  TBD.

Bug description:
  SRU Justification

  Impact:
     The upstream process for stable tree updates is quite similar
     in scope to the Ubuntu SRU process, e.g., each patch has to
     demonstrably fix a bug, and each patch is vetted by upstream
     by originating either directly from a mainline/stable Linux tree
     or a minimally backported form of that patch. The 4.4.136 upstream
     stable stable patch set is now available. It should be included
     in the Ubuntu kernel as well.

     git://git.kernel.org/

  TEST CASE: TBD

     The following patches from the 4.4.136 stable release shall be
     applied:

* Linux 4.4.136
* sparc64: Fix build warnings with gcc 7.
* mm: fix the NULL mapping case in __isolate_lru_page()
* fix io_destroy()/aio_complete() race
* Kbuild: change CC_OPTIMIZE_FOR_SIZE definition
* drm/i915: Disable LVDS on Radiant P845
* hwtracing: stm: fix build error on some arches
* stm class: Use vmalloc for the master map
* scsi: scsi_transport_srp: Fix shost to rport translation
* MIPS: prctl: Disallow FRE without FR with PR_SET_FP_MODE requests
* MIPS: ptrace: Fix PTRACE_PEEKUSR requests for 64-bit FGRs
* iio:kfifo_buf: check for uint overflow
* dmaengine: usb-dmac: fix endless loop in usb_dmac_chan_terminate_all()
* i2c: rcar: revoke START request early
* i2c: rcar: check master irqs before slave irqs

* ASoC: Intel: sst: remove redundant variable dma_dev_name
* rtlwifi: rtl8192cu: Remove variable self-assignment in rf.c
* cfg80211: further limit wiphy names to 64 bytes
* selinux: KASAN: slab-out-of-bounds in xattr_getsecurity
* tracing: Fix crash when freeing instances with event triggers
* Input: elan_i2c_smbus - fix corrupted stack
* Revert "ima: limit file hash setting by user to fix and log modes"

  == Fix ==

  Backport the following 3 commits:
   * scsi: iscsi: target: Fix conn_ops double free
   * scsi: iscsi: target: Set conn->sess to NULL when
     iscsi_login_set_conn_values fails
   * iscsi target: fix session creation failure handling

  == Regression Potential ==

  Low. Clean cherry-picks that modify a very isolated area.

  == Test ==

  Setup an iSCSI target using the scsi_target_user module and
  tcmu_runner. Setup an initiator to connect to the target and do IOs.
  Reboot the target. When the target comes back, the kernel falls over
  when the initiator tries to re-connect.

  == Fix ==

  Backport commit 6c971c09f387 ("drm/ast: Fixed system hanged if disable
  P2A")

  
  == Regression Potential ==

  Low. The patch only touches the ast driver and the modifications are
  fairly small. The patch is also in Xenial (via a stable upstream
  update) and received testing there.

  == Test Case ==

  Booted a patched kernel on HW to verify it comes up without stuck CPU
  warnings.

[Kernel-packages] [Bug 1833047] [NEW] MDS: CPU buffers are not cleared on all paths from kernel to userspace

[Juerg Haefliger]

Private bug reported:

The current implementation is incomplete and there are paths from kernel
to userspace on which the CPU buffers are not cleared.

Fix that by backporting the MDS_USER_CLEAR_CPU_BUFFERS macro from stable
3.16 and use that in assembly entry/exit code.

  FYI: This blocks bug 1781526 - once this one here is resolved we can
  go on with SRU considerations for 1781526

  --- Comment From jhop...@us.ibm.com 2018-08-20 17:12 EDT---

  Hi, in some environments it was observed that this qemu patch to
  enable THP made it more likely to hit guest migration issues, however
  the following kernel patch resolves those migration issues:

  
https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=c066fafc595eef5ae3c83ae3a8305956b8c3ef15
  KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()

  Once merged upstream, it would be good to include that change as well
  to avoid potential migration problems. Should I open a new bug for
  that or is it better to track here?

  Note Paelzer: I have not seen related migration issues myself, but it
  seems reasonable and confirmed by IBM.
