  Python 2.7.12 performance regression

Bug description:
  SRU: Looks like only the math.o build without -fPIC makes it into the
  SRU. There shouldn't be any regression potential when building without
  -fPIC for the static interpreter.  Acceptance criteria is running the
  benchmarks and not showing any performance regressions.

  I work on the OpenStack-Ansible project and we've noticed that testing
  jobs on 16.04 take quite a bit longer to complete than on 14.04.  They
  complete within an hour on 14.04 but they normally take 90 minutes or
  more on 16.04.  We use the same version of Ansible with both versions
  of Ubuntu.

  After more digging, I tested python performance (using the
  'performance' module) on 14.04 (2.7.6) and on 16.04 (2.7.12).  There
  is a significant performance difference between each version of
  python.  That is detailed in a spreadsheet[0].

  I began using perf to dig into the differences when running the python
  performance module and when using Ansible playbooks.  CPU migrations
  (as measured by perf) are doubled in Ubuntu 16.04 when running the
  same python workloads.

  I tried changing some of the kerne.sched sysctl configurables but they
  had very little effect on the results.

  I compiled python 2.7.12 from source on 14.04 and found the
  performance to be unchanged there.  I'm not entirely sure where the
  problem might be now.

  We also have a bug open in OpenStack-Ansible[1] that provides
  additional detail. Thanks in advance for any help you can provide!

[Group.of.nepali.translators] [Bug 1527727] Re: grub-probe for zfs assumes all devices prefix with /dev, ignoring /dev/disk/...

[Scott Moser]

I've marked this 'Fix Released' in xenial as Ubuntu's package in xenial
at 0.6.5.6-0ubuntu3 which has the fix at [1] as mentioned in comment 29.
Further, my experience with our zfs work in curtin indicates that it is
fixed.

  [Impact]
  Installs over ZFS where a ZFS disk is expected to be used as a root device.

  [Test case]
  - Run update-grub on a system with a ZFS root filesystem.

  [Regression Potential]
  Installs relying on the current broken behavior to avoid listing other 
operating systems in grub menu may find that new entries are added.

  ---

  update-grub runs /usr/sbin/grub-probe

  Without libzfslinux support compiled in, /usr/sbin/grub-probe runs
  ["zpool", "status", poolname] to find out ZFS info.

  zpool responds with device names as used at (I think!) pool creation
  time. Often, this is /dev/disk/by-id/... names, without the path.

  grub-probe then parses the output, and takes the names of devices, and
  if they do not start with a "/", it prepends "/dev/".

  It then tests the existence of the path name of the device. it fails.

  grub-probe then returns  something like

  /usr/sbin/grub-probe: error: failed to get canonical path of `/dev
  /ata-ST31000333AS_-part1'.

  The actual path is of course /dev/disk/by-
  id/ST31000333AS_-part1

  It can prepend smarter than "/dev" or it can understand ZFS natively,
  to fix the problem.

Title:
  Support rfkill-any led trigger for Fujitsu u727

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

Bug description:
  I got new HW from our supplier, which is the Fujitsu u7x7 laptop series based 
on Skylake hardware.
  It has a single rfkill button and a single LED for wlan and bluetooth. Both 
device driver currently provide a single rfkill trigger, so the led could just 
be assigned to one. As a result the upstream kernel got a new "rfkill-any" led 
trigger to correctly handle the led with multiple rfkill devices. That was 
added by one of the fujitsu-laptop maintainers and the driver sets it as the 
default trigger.

  commit 9b8e34e211b15af429b72388a8f2b3b1823d172e
  Author: Michał Kępień 
  Date:   Fri Jan 6 07:07:47 2017 +0100

  rfkill: Add rfkill-any LED trigger

  Normally I would simply patch the affected modules using DKMS, like the 
i915_bpo driver, fujitsu-laptop and snd_hda_codec_realtek to support the HW 
without messing with the kernel packages.
  I'm currently waiting for some reviews, like 
https://www.spinics.net/lists/platform-driver-x86/msg14606.html

  But the rfkill support is compiled in, so I can't patch it using DKMS.

  So my first proposed fix would be to include a backport of this patch.
  Alternatively rfkill can be compiled as a module, so I can patch it
  and provide an updated module.

  It requires updated firmwares to enable it.

  [Test Case]
  After applying the required firmwares, it can search APs and connect to the 
network.

  [Regression Potential]
  Although the new firmware overwrite the old one, considering it exists in 
linux-firmware git tree and didn't get any update for 3 month, it should be 
good with no regression.

  [Impact]

  Currently the DKMS package fails to install in supported custom
  kernels that are based on 4.11 or 4.13. That includes the current 4.11
  hwe-edge and the upcoming 4.13 hwe-edge kernels and some of the custom
  and cloud kernels as well.

  [Test Case]

  Install the DKMS package with the 4.13 hwe-edge kernel from -proposed.
  The package installation should proceed without any errors.

  [Regression Potential]

  Although new patches were added, the regression risk is very low since
  the new changes are conditionally compiled based on the kernel
  version.

  Besides that the new package was tested with the following kernels in
  an amd64 environment:

  - linux-generic 4.4
  - linux-hwe 4.10
  - linux-hwe-edge 4.11
  - linux-hwe-edge 4.13 (from xenial-proposed)
  - linux-azure 4.11
  - linux-azure-edge 4.13 (which is in process of getting promoted to
xenial-proposed)

   * libzstd v0.5.1 is an experimental version,
     which generates and read an experimental format
     incompatible with official libzstd v1+ format.

   * Backporting a newer version >= v1.0, such as artful's v1.3.1,
     fixes this issue

   * This backport/SRU is being requested by upstream.

  [Test Case]

   * with the pristine package from each release, compress a big file.
  For example, /usr/bin/snap. Name the resulting compressed file
  according to the version that was used to compress it, like this:

  Xenial:
  $ zstd /usr/bin/snap -o snap.0.5.1.zst
  Compressed 15528016 bytes into 4134889 bytes ==> 26.63%

  Zesty:
  $ zstd /usr/bin/snap -o snap.1.1.2.zst
  /usr/bin/snap: 30.59%   (10825608 => 3311295 bytes, snap.1.1.2.zst)

   * Upgrade to the package made available through this SRU and compress
  it again:

  Xenial:
  $ zstd /usr/bin/snap -o snap.1.3.1.zst
  /usr/bin/snap: 25.11%   (15528016 => 3899137 bytes, snap.1.3.1.zst)

  Zesty:
  $ zstd /usr/bin/snap -o snap.1.3.1.zst
  /usr/bin/snap: 30.59%   (10825608 => 3311290 bytes, snap.1.3.1.zst)

  * Uncompress all the generated files using the new version. This
  proves it can handle files compressed by the old one:

  Xenial:
  $ zstd -d snap.0.5.1.zst -o snap.0.5.1
  snap.0.5.1.zst  : 15528016 bytes
  $ zstd -d snap.1.3.1.zst -o snap.1.3.1
  snap.1.3.1.zst  : 15528016 bytes

  Zesty:
  $ zstd -d snap.1.1.2.zst -o snap.1.1.2
  snap.1.1.2.zst  : 10825608 bytes
  $ zstd -d snap.1.3.1.zst -o snap.1.3.1
  snap.1.3.1.zst  : 10825608 bytes

   * Take md5sums of all uncompressed files and the original. They must
  of course match:

  Xenial:
  $ md5sum /usr/bin/snap snap.0.5.1 snap.1.3.1
  0fa4fa69d79ef4685aaa93be5b3aa33f  /usr/bin/snap
  0fa4fa69d79ef4685aaa93be5b3aa33f  snap.0.5.1
  0fa4fa69d79ef4685aaa93be5b3aa33f  snap.1.3.1

  Zesty:
  $ md5sum /usr/bin/snap snap.1.1.2 snap.1.3.1
  ba0a3ef5f519688bc5b0b58f190e73a4  /usr/bin/snap
  ba0a3ef5f519688bc5b0b58f190e73a4  snap.1.1.2
  ba0a3ef5f519688bc5b0b58f190e73a4  snap.1.3.1

  * Downgrade zstd back to the original version of the ubuntu release
  you are testing:

  Xenial:
  $ sudo apt install zstd=0.5.1-1

  Zesty:
  $ sudo apt install zstd=1.1.2-1 libzstd1=1.1.2-1

  * Try to decompress the zst file created with the 1.3.1 version from the 
previous test. In xenial only, it should fail to recognize the format:
  $ zstd -d snap.1.3.1.zst -o /dev/null
  zstd: /dev/null already exists; do you wish to overwrite (y/N) ? y
  zstd: snap.1.3.1.zst: not in zstd format

  In zesty it should work:
  $ zstd -d snap.1.3.1.zst -o snap.1.3.1-new
  snap.1.3.1.zst  : 9909192 bytes

  * Still in zesty, compare the md5, which should match:
  $ md5sum snap.1.3.1-new /usr/bin/snap
  7c980688861eef598a56c7970d952028  snap.1.3.1-new
  7c980688861eef598a56c7970d952028  /usr/bin/snap

  [Regression Potential]

   * During transition, if some user switches to newer zstd version, and
  then send compressed data to another user has not yet updated zstd,
  the receiver will not be able to decompress as long as he does not
  update.

   * Note though that newer version contains a compatibility module
  which makes it able to read data generated by older versions, such as
  v0.5.1. Any existing document compressed with v0.5.1 will still be
  readable after update to v1.3.1.

  [Other Info]

   * Linux kernel 4.14 now integrates zstd compression / decompression,
  primarily for BtrFS and SquashFS, with patches available for reiser4,
  zram, and initrd. Kernel version does not support compatibility
  module, hence cannot read data from v0.5.1. Userland tools associated
  with these services will fail if they link to Ubuntu LTS libzstd, as
  generating incompatible data.

   * On top of the incompatible format issue, libzstd v0.5.1 API is old
  and missing several features that applications relying on libzstd
  need, such as streaming interface, or bulk processing for dictionary
  compression.

  --- Original description ---

  Please backport libzstd 1.3.1+dfsg-1 (universe) from artful to xenial.

  Reason for the backport:
  
  Current version in Xenial is v0.5.1,
  it's an experimental version, using its own, incompatible format.
