  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:

     v5.4.94 upstream stable release
     from git://git.kernel.org/

  gpio: mvebu: fix pwm .get_state period calculation
  futex: Ensure the correct return value from futex_lock_pi()
  futex: Replace pointless printk in fixup_owner()
  futex: Provide and use pi_state_update_owner()
  rtmutex: Remove unused argument from rt_mutex_proxy_unlock()
  futex: Use pi_state_update_owner() in put_pi_state()
  futex: Simplify fixup_pi_state_owner()
  futex: Handle faults correctly for PI futexes
  HID: wacom: Correct NULL dereference on AES pen proximity
  io_uring: Fix current->fs handling in io_sq_wq_submit_work()
  tracing: Fix race in trace_open and buffer resize call
  arm64: mm: use single quantity to represent the PA to VA translation
  SMB3.1.1: do not log warning message if server doesn't populate salt
  tools: Factor HOSTCC, HOSTLD, HOSTAR definitions
  dm integrity: conditionally disable "recalculate" feature
  writeback: Drop I_DIRTY_TIME_EXPIRE
  fs: fix lazytime expiration handling in __writeback_single_inode()
  Linux 5.4.94
  UBUNTU: upstream stable to v5.4.94

Bug description:
  [Impact]

  A mix of incoming TCP traffic, forwarding packets and saturating the
  link results in lan78xx TX queue timeouts which brings the network
  interface down.

  [Test Case]

  Se comment #99 below.

  [Where Problems Could Occur]

  Probably lost or corrupted TCP packets. Most likely not worse than
  what we're currently seeing.

  [Original Description]

  Desciption changed:
  Raspberry Pi 3 network partially dies (transmission doesn't work, reception 
still does) shortly after a burst of network load over IPv6, when IPv6 
connectivity is provided by a tunnel from tunnelbroker.net. The triggering load 
is typically an HTTP(S) download, and replication can be done without actually 
saving the file (wget -O /dev/null ...). Problem happens within downloading ~10 
GB, usually withinthe first 1 GB of traffic)
  Replication is 100% as long as _all_ of the following conditions are met
  - 6in4 tunnel to HE.net set up with netplan
  - ipv6 rules applied (netfilter-persistent)
  - ipv6 forwarding enabled (edit /etc/sysctl.conf)

  There are some drivers are required to enable Advantech UNO-420 platform.

  [Fix]
  Advantech is submitting their drivers to upstream for review, and considering 
that the patches are new drivers, it should be safe pull them back to ubuntu 
kernel.
  https://lkml.org/lkml/2021/1/18/500

  [Test]
  Verified on Advantech UNO-420 platform.

  [Where problems could occur]
  Those commits create 3 new drivers, and do not modify any existing drivers. 
Should introduce no regression.

   intel-hid is not loaded on Intel Tiger Lake and Rocket Lake platforms 
because the existing
   hardware ids "INT33D5" aren't used in BIOS.

  [Fix]

   New ids "INTC1051" and "INTC1054" are to be added to intel-hid kernel
  driver.

  [Test Case]

   This was tested on a Rocket Lake platform and intel-hid was loaded
  correctly as kernel log below:

   [ 2.938964] input: Intel HID 5 button array as
  /devices/platform/INT1054:00/input/input11

  [Where problems could occur]

   None.

   New IDs were added for new platforms. Previous platforms will not be
  affected.

Bug description:
  [Impact]
  * Currently linux-kvm derivative doesn't have CONFIG_PCI_MSI (and its 
dependency options) enabled. The goal for such derivative is to be minimal and 
boot as fast as possible in virtual environments, hence most config options 
were dropped.

  * Happens that MSI/MSI-X are the de facto drivers' standard with
  regards to interrupts, and as such the hot path is optimized for MSIs.
  Boot testing with that config enabled showed that we have improvements
  in boot time (details in next section).

  * Also, performance-wise MSIs are a good idea too, since it usually
  allows multiple queues in network devices and KVM is more optimized to
  MSIs in comparison with regular IRQs - tests (detailed in next
  section) showed performance improvements in virtio devices with MSIs.

  * Based on that findings, we are hereby enabling MSIs for the linux-
  kvm derivatives in all series (Bionic / Focal / Groovy / Hirsute) -
  notice that Xenial already has that config option enabled.

  [Test Case]
  * All below tests were performed in a x86-64 KVM guest with 2 VCPUs and 2GB 
of RAM, running in a Focal host. Three runs of each test were performed, and we 
took the average.
   
  * Boot time test (measured by dmesg timestamp) showed an improvement of ~21%, 
the following chart exhibiting the data: 
https://kernel.ubuntu.com/~gpiccoli/MSI/boot_time.svg
  We also timed the full boot until the login prompt is available, we had a 
decrease from ~1 second.

  * The storage test was performed with the fio tool, using a virtio-blk empty 
disk. The following arguments were used:
  fio --filename /dev/vdc --rw=rw --runtime 600 --loops 100 --ioengine libaio 
--numjobs 2 --group_reporting

  On average we had a ~4.5% speedup in both reads and writes, the
  following chart represents the data:
  https://kernel.ubuntu.com/~gpiccoli/MSI/fio_storage.svg

  * From the network perspective, we've used iPerf with the following
  arguments: iperf -c  -t 300 (server was the host machine). On
  average, the performance improvement was ~8%, as per the following
  chart: https://kernel.ubuntu.com/~gpiccoli/MSI/iperf_network.svg

  [Where problems could occur]
  * Given that the main linux package (generic) and basically all other 
derivatives already enable this option, and given that MSIs are the standard 
with regards to interrupts from drivers point-of-view, it's safe to say the 
risks are minimal, likely smaller than not enabling MSIs (since the hot path is 
usually more tested/exercised).

  * That said, problems could occur if we have bugs in MSI-related code
  in drivers or in PCI MSI core code, then those potential problems that
  would already affect all other derivatives begin to affect linux-kvm
  with this change.

  The issue is actually harmless, so replace the WARN macro with dbg

  No more scary stack trace in dmesg after applying the patch.

  [Where problems could occur]
  This patch doesn't bring any behavior change, so there won't be any

  [Impact]
  Building these modules wastes build time, and also may potentially lead to 
unnecessary updates.

  [Fix]
  Set do_dkms_nvidia = false on amd64.mk.

  [Test case]
  Build test the kernel.

  [Potential regression]
  Missing signed bits for these modules, in case someone uses them without LRMs.

  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:

Bug description:
  [Impact]
  We had a Dell machine, this machine was enabled with ubuntu 4.4
  kernel before, but recently the hdmi audio on this machine stopped
  working with the latest ubuntu 4.4. kernel. The system can't detect
  its plugging and can't output sound to it anymore.

  [Fix]
  This is because we backported a patch from stable updates, and that
  patch is for v5.2 kernel, if we backported it to 4.4 kernel, we need
  to do some change, and also we need to backport one more patch from
  stabe kernel.

  [Test Case]
  Connect a monitor to the machine and boot up, after booting up, we
  could see the hdmi audio is found, and play sound to the hdmi audio,
  we could hear the sound from monitor.

  
  [Regression Risk]
  It is possible to make the hdmi audio fail to work after applying this
  patchset, like the hdmi audio can't be detected after plugging a hdmi
  monitor. But this possibility is very low, we tested the patchset on
  many dell and lenovo machines, all worked well.

    if [ $? -ne 0 ];then
  echo "SKIP: fou: iproute2 too old"
  return 1
    fi

  It should at least return ksft_skip=4 (or 0 with older release that
  does not support this skip code in kselftest framework)

  == Fix ==
  * 57aefc7c226d ("selftests: net: return Kselftest Skip code for
  skipped tests")

  This patch needs to be backported into Bionic, as some newer tests
  does not exist in Bionic.

  == Test ==
  Tested directly on the affected kernel, the test will be marked as:
  not ok 1..10 selftests:  rtnetlink.sh [SKIP]

  == Regression Potential ==
  Low, changes limited to test scripts. And the kselftest framework in
  Bionic can handle this ksft_skip=4 return code properly, tests won't
  be marked as failed because of this.

  Although IMO in this case the test should be marked as PASS instead of
  SKIP in the end, as not all tests were skipped, but that's something
  we could fix with upstream in the future.

  KIOXIA NVMe has a 10% chance to stop working after S3.

  [Fix]
  Enable ACS quirk on Intel CML root port.

  [Test]
  With the patch applied, KIOXIA NVMe always works after S3.

  [Regression Potential]
  ACS works at hardware level, so I can't really assess the risk of
  regression. Since Intel confirmed CML also needs ACS quirk, we can only
  trust them.

[Kernel-packages] [Bug 1894591] Re: clock: overriding the clocksource should select the requested clocksource

Title:
  clock: overriding the clocksource should select the requested
  clocksource

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

Bug description:
  BugLink: https://bugs.launchpad.net/bugs/1894591

  [Impact]

  The default clocksource for a KVM VM is kvm-clock, and I happen to
  need tsc.

  $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
  kvm-clock

  If I edit /etc/default/grub and append "clocksource=tsc" to
  GRUB_CMDLINE_LINUX_DEFAULT and reboot, I find the clocksource is still
  kvm-clock.

  $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
  kvm-clock

  I can work around this by telling the kernel that the tsc clocksource
  is reliable, before the watchdog has a chance to see for itself that
  it is reliable:

  GRUB_CMDLINE_LINUX_DEFAULT="clocksource=tsc tsc=reliable"

  $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
  tsc

  If I override the clocksource, the kernel should respect my wishes and
  I should receive the requested clocksource.

  [Fix]

  The fix landed in Linux 4.9 in the below commit:

  commit 36374583f9084cdab4b5dcf5521a3ce55bebb9fa
  Author: Kyle Walker 
  Date:   Sat Aug 6 12:07:30 2016 -0400
  Subject: clocksource: Defer override invalidation unless clock is unstable
  Link: 
https://github.com/torvalds/linux/commit/36374583f9084cdab4b5dcf5521a3ce55bebb9fa

  The commit ensures the override doesn't get cleared before the
  watchdog has had an opportunity to check if the clocksource is stable
  or not. However, if the clocksource is known to be unstable at this
  point in time, it will clear the override and return to the default.

  This is a clean cherry-pick to the Xenial 4.4 kernel.

  [Testcase]

  Start up a KVM VM, possibly enable invtsc on the QEMU command line.

  The default clocksource will be kvm-clock:

  $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
  kvm-clock

  If you set the kernel command line to:

  GRUB_CMDLINE_LINUX_DEFAULT="clocksource=tsc"

  If you reboot, you will see the incorrect option of kvm-clock:

  $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
  kvm-clock

  There is a test kernel available in the below ppa, with the commit
  applied:

  https://launchpad.net/~mruffell/+archive/ubuntu/sf291501-test

  If you install the test kernel, and leave the kernel command line as:

  GRUB_CMDLINE_LINUX_DEFAULT="clocksource=tsc"

  You will get the requested clocksource:

  $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
  tsc

  You will also get the following in dmesg:

  $ dmesg | grep defer
  [1.002599] clocksource: Override clocksource tsc is not currently HRT 
compatible - deferring

  [Regression Potential]

  This commit changes how the kernel treats clocksource overrides. If
  any users have an override set, but the kernel is clearing the
  override and returning to the default, when they install a patched
  kernel, they will change over to their requested override, which may
  come as a surprise.

  If there is a regression, it will only affect systems who have
  clocksource overrides in place, and in the worst case, will revert the
  system to its default clocksource if the selected clocksource override
  is found to be unstable.

  The commit is well tested, and should not cause any regressions.

[Kernel-packages] [Bug 1891222] Re: Only notify Hyper-V for die events that are oops

2020-08-26 Thread William Breathitt Gray
SRU Template


[Impact]

Currently, Hyper-V may be notified of a panic for any die event.

However, this results in false panic notifications for various user
space traps that are die events.

The following commit fixes this by ignoring die events that is not an
oops:

608a973bd52e ("Drivers: hv: vmbus: Only notify Hyper-V for die events
that are oops")

[Test Case]

Without the fix in the Linux VM, do the following to demonstrate the
problem:

1. Create a VM in Azure.
2. Run a user space program that does a divide-by-zero. The user space
   program will terminate abnormally because of the error.
3. Monitor notifications in the Azure portal in the Resource Health
   section of the VM. There should be a report that the Linux VM has
   panicked.

With the fix, do the same steps. The panic report in Step #3 should not
happen.

[Regression Potential]

The risk of regression is low. This patch fixes the issue by ignoring
die events that aren't oops.

The upstream LKML thread mentions that DIE_PANIC may also be something
that should be reported, but it doesn't get emitted anywhere so this
might not be significantly different than DIE_OOPS.
