[Jamie Strandboge]

@Frode, I can yes, when I file them. I need to do a bit of work for
simple reproducers/etc/etc to file them. I've added an item to add a
comment to this bug when I do.

  With the following use of overlayfs, we get a disconnected path:

  $ cat ./profile
  #include 
  profile foo {
    #include 

    capability sys_admin,
    capability sys_chroot,
    mount,
    pivot_root,

  int main(int argc, char* argv[]) {
  int i = 0;
  int len = 0;
  int ret = 0;
  char* options;

  if (geteuid())
  unshare(CLONE_NEWUSER);
  unshare(CLONE_NEWNS);

  for (i = 1; i < argc; i++) {
  if (i == 1) {
  len = strlen(argv[i]) + strlen("upperdir=,lowerdir=/") + 2;
  options = alloca(len);
  ret = snprintf(options, len, "upperdir=%s,lowerdir=/", argv[i]);
  }
  else {
  len = strlen(argv[i]) + strlen("upperdir=,lowerdir=/mnt") + 2;
  options = alloca(len);
  ret = snprintf(options, len, "upperdir=%s,lowerdir=/mnt", 
argv[i]);
  }

  mount("overlayfs", "/mnt", "overlayfs", MS_MGC_VAL, options);
  }

  chdir("/mnt");
  pivot_root(".", ".");
  chroot(".");

  chdir("/");
  execl("/bin/bash", "/bin/bash", NULL);
  }

  $ sudo apparmor_parser -r ./profile && aa-exec -p foo -- ./a.out /tmp

  Dec 12 14:31:38 localhost kernel: [57278.040216] audit: type=1400

comm="a.out" requested_mask="x" denied_mask="x" fsuid=1000 ouid=0

  With the above, the expectation was for the denial to be /mnt/bin/bash. There 
are three ways forward:
  1. the correct solution is to patch overlayfs to properly track the loopback, 
but this will take a while, may ultimately be unachievable. UPDATE: upstream is 
currently working on this and Ubuntu will engage with them
  2. we could rely on the fact that overlayfs creates a private unshared 
submount, and provide a way to not mediate the path when that is present, and 
tagged. This would take a bit of time, and might be the preferred method over 1 
longer term
  3. we could extend attach_disconnected so that we can define the attach root. 
Eg, we can use profile foo (attach_disconnected=/mnt) {} such that '/bin/bash' 
maps to '/mnt/bin/bash'. UPDATE: THIS IS NOT VIABLE

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

[FZ]

Update: After reboot, the touchpad is not back to being completely dead
(I sensed this was going to happen). Obviously it's supported since it
worked flawlessly at one point so what could possibly be the problem and
where to look for it?

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services

[Joseph Salisbury]

Do we know which kernel version caused the regression?  If so, I can
review the commits or perform a bisect if needed.

  [Hyper-V] LIS daemons fail to start after disable/re-enable VM
  integration services

Bug description:
  Issue description: Hyper-V daemons fail to start after disable/re-
  enable VM integration services.

  Platform: host independent
  Affected daemons - KVP, FCOPY and VSS.

  Distribution name and release: Ubuntu 16.04, Ubuntu 17.04
  Kernel version: 4.11.0-rc7-next-20170421 (for Ubuntu 16.04), 
4.10.0-19-generic (for Ubuntu 17.04)

  Repro rate: 100%

  Steps to reproduce:
  1.Start VM with Guest Services enabled (FCopy daemon starts automatically)
  2.Go to File > Settings > Integration Services, uncheck Guest Services 
and apply (FCopy daemon will stop at this point)
  3.Re-enable Guest Services from VM Settings (Fcopy daemon is not running).
  This is the issue. systemd monitors for the service and if we have the hook 
for the Guest Service, it tries to start the daemon again.
  systemd attempt to start any of the LIS daemons will fail, but manually 
executing the daemon binary, it will start the daemon.

  Additional Info:
  - the steps above can be repro'd with KVP / Data Exchange integration service 
as well.
  - Manually starting hv_fcopy_daemon works fine.
  - other distros (RHEL) does not have this behavior, the LIS daemons are 
started automatically by systemd once we re-enable the integration service.

  On the upstream kernel and the upstream hv daemons, these messages are 
recorded in syslog, once we re-enable the Guest service:
  HV_FCOPY: pread failed: Bad file descriptor
  systemd[1]: hv-fcopy-daemon.service: Main process exited, code=exited, 
status=1/FAILURE
  systemd[1]: hv-fcopy-daemon.service: Unit entered failed state.
  systemd[1]: hv-fcopy-daemon.service: Failed with result 'exit-code'.

[Kernel-packages] [Bug 1697395] Re: Thunderbolt devices don't work if connected during boot

[dragon788]

Kai-Heng, did you run the command as root? Otherwise you may want to
`sudo su` and run the loop or "prime" your sudo by running `sudo echo`
(to get prompted for you password once) and then use the same loop but
instead of `> /path/to/file` use `| tee /path/to/file` and see if you
get different results.

I will bookmark this to test after my next restart, as I'm seeing the
same issue on boot, and I don't know that changing the system hardware
test from Automatic to Thorough or Quick in the BIOS will make a
difference.

  Thunderbolt devices don't work if connected during boot

Status in linux package in Ubuntu:

Bug description:
  I am using a Dell XP 15 9550, if my Dockingstation (Dell TB16) is
  connected during boot time, all the USB devices (like Keyboard,
  Ethernet, ...) are only working while in grub boot menu. After booting
  they stop working.

  The two 4k screens which are connected to the dock, are working
  properly in boot menu and after booting. If booting into Windows
  everything is working, only linux is affected.

  Disconnecting and reconnecting the dock solves this problem.

  I have created the bug-report directly after boot, where the USB
  devices are not working and attached "lspci-vnvn_after_reconnect.log"
  after reconnecting the dock.

[Kernel-packages] [Bug 1676635] Re: [Hyper-V] Implement Hyper-V PTP Source

[Alex Ng]

Hi Marcelo,

I kicked the tires on 4.4.0-85-generic kernel from xenial-proposed. The
fixes look good. I see the PTP device and TimeSync is not causing "Time
has been changed" messages in systemd. I also see that apt-daily timer
is no longer being randomly delayed due to the clock changes.

Bug description:
  Please include the following upstream commit into lts-xenial, 16.04
  HWE, Yakkity, and Zesty. This will improve the behavior of timesync on
  Hyper-V hosts while simultaneously using network time sync protocols
  like NTP.

  hv_utils: implement Hyper-V PTP source

  With TimeSync version 4 protocol support we started updating system time
  continuously through the whole lifetime of Hyper-V guests. Every 5 seconds
  there is a time sample from the host which triggers do_settimeofday[64]().
  While the time from the host is very accurate such adjustments may cause
  issues:
  - Time is jumping forward and backward, some applications may misbehave.
  - In case an NTP server runs in parallel and uses something else for time
    sync (network, PTP,...) system time will never converge.
  - Systemd starts annoying you by printing "Time has been changed" every 5
    seconds to the system log.

  Instead of doing in-kernel time adjustments offload the work to an
  NTP client by exposing TimeSync messages as a PTP device. Users may now
  decide what they want to use as a source.

  I tested the solution with chrony, the config was:

   refclock PHC /dev/ptp0 poll 3 dpoll -2 offset 0

  The result I'm seeing is accurate enough, the time delta between the guest
  and the host is almost always within [-10us, +10us], the in-kernel 
solution
  was giving us comparable results.

  I also tried implementing PPS device instead of PTP by using not currently
  used Hyper-V synthetic timers (we use only one of four for clockevent) but
  with PPS source only chrony wasn't able to give me the required accuracy,
  the delta often more that 100us.

[Kernel-packages] [Bug 1408106] Re: attach_disconnected not sufficient for overlayfs

[Andres Rodriguez]

@Frode,

Users running 2.2 *already* have the apparmor=0 work around for
*ephemeral* environments only.

For users running previous versions, we recommend you upgrade
immediately, provided that 2.0 and 2.1 are out of support. If you decide
not to upgrade, your options are:

1. Use a HWE kernel (such as hwe-16.04). 
https://bugs.launchpad.net/cloud-init/+bug/1701297/comments/21
2. Use apparmor=0 as a global/machine kernel param (this will result in the 
deployed machine with apparmor disabled)

Marking this invalid for MAAS provided the bug is overlayfs.


** Changed in: maas
   Status: Incomplete => Invalid

  With the following use of overlayfs, we get a disconnected path:

  $ cat ./profile
  #include 
  profile foo {
    #include 

    capability sys_admin,

  int i = 0;
  int len = 0;
  int ret = 0;
  char* options;

  if (geteuid())
  unshare(CLONE_NEWUSER);
  unshare(CLONE_NEWNS);

  for (i = 1; i < argc; i++) {
  if (i == 1) {
  len = strlen(argv[i]) + strlen("upperdir=,lowerdir=/") + 2;
  options = alloca(len);
  ret = snprintf(options, len, "upperdir=%s,lowerdir=/", argv[i]);
  }
  else {
  len = strlen(argv[i]) + strlen("upperdir=,lowerdir=/mnt") + 2;
  options = alloca(len);
  ret = snprintf(options, len, "upperdir=%s,lowerdir=/mnt", 
argv[i]);
  }

  mount("overlayfs", "/mnt", "overlayfs", MS_MGC_VAL, options);
  }

  chdir("/mnt");
  pivot_root(".", ".");
  chroot(".");

  chdir("/");
  execl("/bin/bash", "/bin/bash", NULL);
  }

  $ sudo apparmor_parser -r ./profile && aa-exec -p foo -- ./a.out /tmp
  [255]
  ...
  Dec 12 14:31:38 localhost kernel: [57278.040216] audit: type=1400

comm="a.out" requested_mask="x" denied_mask="x" fsuid=1000 ouid=0

  With the above, the expectation was for the denial to be /mnt/bin/bash. There 
are three ways forward:
  1. the correct solution is to patch overlayfs to properly track the loopback, 
but this will take a while, may ultimately be unachievable. UPDATE: upstream is 
currently working on this and Ubuntu will engage with them
  2. we could rely on the fact that overlayfs creates a private unshared 
submount, and provide a way to not mediate the path when that is present, and 
tagged. This would take a bit of time, and might be the preferred method over 1 
longer term
  3. we could extend attach_disconnected so that we can define the attach root. 
Eg, we can use profile foo (attach_disconnected=/mnt) {} such that '/bin/bash' 
maps to '/mnt/bin/bash'. UPDATE: THIS IS NOT VIABLE

[Kernel-packages] [Bug 1701857] Re: Kernel Oops - unable to handle kernel paging request; RIP: 0010:[] [] fput+0x5/0x90

[Bartong]

I first noticed the problem on kernel 4.4.0-81. The computer froze up a
few times before I started digging into the logs to try and figure out
what was wrong.  It was freezing about 3-4 times per day.

I rolled back to kernel 4.4.0-79, which seemed to be more stable but
still suffered an Oops at least once per day.  Upgraded to 4.4.0-83 when
it became available, but still suffering an Oops occasionally.

Also around this time I was suffering graphics issues where the display
became unresponsive.  There was no kernel oops, but it seemed the
nouveau driver was crashing.  I've switched to the nvidia proprietry
driver, which has resulted in a stable display, but even since then a
kernel oops reoccured.  Most recent log of the oops below.

I'm probably not too keen to go mainline kernel as this is not a testing
system - but could we achieve a similar test if I went for the HWE
kernel (which I think is currently 4.8 ?)

Thank you for your reply!

[Kernel-packages] [Bug 1702749] Re: arm64: fix crash reading /proc/kcore

[dann frazier]

** Description changed:

  [Impact]
  Reading /proc/kcore can lead to a crash on arm64 systems.
+ This was found to cause crashes when, e.g. annotating symbols in a perf top 
session.
  
  [Test Case]
  # cat /proc/kcore > /dev/null
  
  [Regression Risk]
+ 2 upstream patches need to be cherry-picked to fix this. 
+ 
+ The 1st patch is a simplification to the kcore driver that impacts all
+ architectures. Instead of re-checking at read time for vmalloc/module
+ addresses, it just checks for a flag that was set during kcore driver
+ init. This looks correct to me but could of course have an unnoticed
+ bug.
+ 
+ The second patch is arm64-specific, and regression risk has been
+ mitigated by testing on arm64 hardware.

[Kernel-packages] [Bug 1690085] Re: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks

[Marc Rene Schädler]

Was this issue officially confirmed to be a hardware bug in Ryzen processors by 
AMD?
If so, could you provide a link to the statement?

Disabling address space layout randomization (ASLR) seems to alleviate
the problem, but does it solve it?

I am investigating unstable behavior under load which could be related.
There, disabling ASLR is not sufficient!
People suggest to increase SOC voltages, use specific versions of the kernel 
and the like.
See https://community.amd.com/thread/215773?start=135=0 for more info.

Bug description:
  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using 
latest BIOS available (1.52)

  We are running Ubuntu 17.04 (amd64), we've tried different kernel version, 
native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
  Tested kernel version:

  native 17.04 kernel
  4.10.15

  Issues are the same, we're getting random freeze on the machine.

  Here is kern.log entry when happening :

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

  
  Thanks

[Kernel-packages] [Bug 1701085] Re: package linux-image-4.4.0-83-generic (not installed) failed to install/upgrade: subprocess new pre-installation script returned error exit status 128

[Steven Pemberton]

Bear in mind that this bug report is only of a symptom of the real bug,
which is gnome-software hanging during an update (which it seems to do
regularly).

So doing the install and update as explained above fixes the symptom,
but not the bug.

[Kernel-packages] [Bug 1702164] Re: Kernel panic - not syncing: Fatal exception in interrupt

[Khaled Massad]

Yes, I restored last kernel on another VM, and it worked fine
But panic just removed after kernel crashed, and server rebooted by itself 3 
times.
it's up since 2 days with crash.

[Kernel-packages] [Bug 1614789] Re: zfs.target should not require zfs-share.service

[Colin Ian King]

** Changed in: zfs-linux (Ubuntu)
   Status: In Progress => Fix Released

-- 
You received this bug notification because you are a member of Kernel
Packages, which is subscribed to zfs-linux in Ubuntu.
https://bugs.launchpad.net/bugs/1614789

Title:
  zfs.target should not require zfs-share.service

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

Bug description:
  == SRU Xenial ==

  [Justification]

  Currently package zfsutils-linux contains systemd target file 
/lib/systemd/system/zfs.target that specifies following dependencies:
  Requires=zfs-mount.service
  Requires=zfs-share.service
  Wants=zed.service

  zfs-share.service is not essential in setups where file sharing is not
  used, or when it is configured without the use of the zfs utility. The
  user may therefore choose to mask this service. However, doing so has
  an unexpected and confusing effect, preventing zfs from starting on
  boot at all. This is because zfs.target is the only zfs-related unit
  that is wanted by multi-user.target, and if one of its required
  services is masked, zfs.target is skipped, together with zfs-
  mount.service. A solution is to replace "Requires=zfs-share.service"
  with "Wants=zfs-share.service".

  [Testcase]
  Steps to reproduce:
  systemctl mask zfs-share.service
  reboot

  Expected results:
  Module zfs is loaded
  zfs-mount.service is active and ZFS filesystems are mounted
  ZFS filesystems are not shared

  Observed results:
  Module zfs is not loaded
  ZFS filesystems are not mounted
  zpool status produces an error:
  "The ZFS modules are not loaded.
  Try running '/sbin/modprobe zfs' as root to load them."

  With the fix, the modules are loaded and zfs filesystems are mounted

  [Fix]
  A solution is to replace "Requires=zfs-share.service" with 
"Wants=zfs-share.service".

  [Regression Potential]
  Minimal, this affects the start up of a service that should be starting and 
currently isn't. Limited to just this specific scenario.

[Kernel-packages] [Bug 1408106] Re: attach_disconnected not sufficient for overlayfs

[Frode Nordahl]

This problem has surfaced again with recent MAAS Ubuntu images. One
report in bug 1701297. I have information about at least two other end
users hit by the problem.

Adding a workaround by setting apparmor=0 kernel parameter in MAAS 2.2
will not help users that are running previous versions.

@jdstrand Would you care to reference the other bugs you created from
your investigation?

but this will take a while, may ultimately be unachievable. UPDATE: upstream is 
currently working on this and Ubuntu will engage with them
  2. we could rely on the fact that overlayfs creates a private unshared 
submount, and provide a way to not mediate the path when that is present, and 
tagged. This would take a bit of time, and might be the preferred method over 1 
longer term
  3. we could extend attach_disconnected so that we can define the attach root. 
Eg, we can use profile foo (attach_disconnected=/mnt) {} such that '/bin/bash' 
maps to '/mnt/bin/bash'. UPDATE: THIS IS NOT VIABLE

[Kernel-packages] [Bug 1702368] Re: Mounted sshfs filesystems sometimes prevent suspend

[Robie Basak]

A workaround for my gvim-based hang is to not have gvim open on the
sshfs when I suspend. I don't have that option with gsd-housekeeping, so
I basically have to unmount sshfs before suspend, which breaks
everything else (eg. open bash prompts). Using "sshfs -o reconnect"
works fine except for this.

  Mounted sshfs filesystems sometimes prevent suspend

Status in gnome-settings-daemon package in Ubuntu:

Bug description:
  Using Ubuntu artful with linux-image-4.10.0-26-generic 4.10.0-26.30
  and sshfs 2.8-1. I use "sshfs -o reconnect" and often run gvim against
  a file on an sshfs filesystem.

  Sometimes when I suspend I get:

  Jul  4 20:59:08 xps kernel: [46684.608740] PM: Syncing filesystems ... done.

  ...
  Jul  4 20:59:08 xps kernel: [46704.620711] Restarting tasks ... done.

  ...and the system fails to suspend.

  AFAICT, this is https://bugzilla.redhat.com/show_bug.cgi?id=656992 and
  https://lists.debian.org/debian-kernel/2011/10/msg00412.html has an
  extensive explanation. The corresponding Debian bug was closed long
  ago due to inactivity. It isn't exactly bug 388419 though since that
  is about behaviour after resume, rather than failure to suspend.

  This affects sshfs-fuse, but it sounds like a full fix would be in the
  kernel. I wonder if it's possible to work around in userspace
  packaging in sshfs-fuse, though, by arranging some action in userspace
  before suspend?

  It seems unlikely that this will be addressed any time soon, but it'd be nice 
to keep a bug open in Launchpad so that users can have a single rallying point.

[Raoul]

Hi Joseph

I have a script that runs the commands you suggest

Not only was this a fresh install but I have flickering icons from time 
to time !

Appears this standalone install may have some more bugs beside this one
!

Thanks Raoul

[Kernel-packages] [Bug 1702368] Re: Mounted sshfs filesystems sometimes prevent suspend

  Mounted sshfs filesystems sometimes prevent suspend

Status in gnome-settings-daemon package in Ubuntu:
  New
Status in linux package in Ubuntu:

Status in sshfs-fuse package in Ubuntu:
  New

Bug description:
  Using Ubuntu artful with linux-image-4.10.0-26-generic 4.10.0-26.30
  and sshfs 2.8-1. I use "sshfs -o reconnect" and often run gvim against
  a file on an sshfs filesystem.

  Sometimes when I suspend I get:

  Jul  4 20:59:08 xps kernel: [46684.608740] PM: Syncing filesystems ... done.
  Jul  4 20:59:08 xps kernel: [46684.613278] PM: Preparing system for sleep

  ...
  Jul  4 20:59:08 xps kernel: [46704.620711] Restarting tasks ... done.

  ...and the system fails to suspend.

  AFAICT, this is https://bugzilla.redhat.com/show_bug.cgi?id=656992 and
  https://lists.debian.org/debian-kernel/2011/10/msg00412.html has an
  extensive explanation. The corresponding Debian bug was closed long
  ago due to inactivity. It isn't exactly bug 388419 though since that
  is about behaviour after resume, rather than failure to suspend.

  This affects sshfs-fuse, but it sounds like a full fix would be in the
  kernel. I wonder if it's possible to work around in userspace
  packaging in sshfs-fuse, though, by arranging some action in userspace
  before suspend?

  It seems unlikely that this will be addressed any time soon, but it'd be nice 
to keep a bug open in Launchpad so that users can have a single rallying point.

[Kernel-packages] [Bug 1702665] [NEW] 4.4.0-83-generic + Docker + EC2 t2.small frequently crashes at cgroup_rmdir GPF

[sorah]

Public bug reported:

We run xenial-based Docker container hosts on EC2 with Amazon ECS.
Recently we refreshed our base image, we started to see frequent panic.

Hosts run Amazon ECS Agent, and the agent automatically creates or
destroys Docker container based on requests onto ECS cluster.

I think this crash is caused by Docker-related operations, because
crashing at cgroups.

Also, we're running several different cluster with another EC2 instance
types, using same image. This problem is only reproducing at t2.small
instances. (We also run c4.large and m4.* clusters)

Our previous image ran 4.4.0-79-generic, and we see no problem with 79.

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu

acelankao,

In 1692836 the same hack mentioned by Kalle was applied.

I am not sure it is a proper fix though as it has not landed upstream:

  Kalle Valo suggested a hack which increased client -> AP TCP performance - so 
it does not look like a firmware issue as I thought originally, rather an

  I experience a very poor 802.11ac performance of a QCA6174 Wireless card

  This is a dev version of Zesty with a recently released 4.10 kernel:

  Testing wireless speed with RT-87U 802.11ac router shows that the
  speed is only 27.3 megabits per second which is very low for an
  802.11ac card:

  iperf -c rtr
  
  Client connecting to rtr, TCP port 5001
  TCP window size: 85.0 KByte (default)

  [ ID] Interval   Transfer Bandwidth
  [  3]  0.0-10.0 sec  32.6 MBytes  27.3 Mbits/sec

  

  For comparison, on the same network (from the same distance to the
  router) I have the following result with an Intel's card (on a 4.8
  kernel, different laptop):

  UX32LN:~$ lspci | grep 7260
  02:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)

  200 Mbps is much better.

I can repeatably get this problem if I boot without a network connection.I 
get the message "waiting for a start job to complete ... Raise Network 
Interfaces" followed by "NMI Watchdog: BUG: soft lockup - CPU#1 stuck for 22s! 
[swapper/1:0]"
Booting with a network cable attached has no problems.
This is on 4.10.0-26 and AMD Athlon 64 X2, using an AMD GPU.  Nouveau module is 
not loaded.

Title:
  4.4.0-83-generic + Docker + EC2 t2.small frequently crashes at
  cgroup_rmdir GPF

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  We run xenial-based Docker container hosts on EC2 with Amazon ECS.
  Recently we refreshed our base image, we started to see frequent
  panic.

  Hosts run Amazon ECS Agent, and the agent automatically creates or
  destroys Docker container based on requests onto ECS cluster.

  I think this crash is caused by Docker-related operations, because
  crashing at cgroups.

  Also, we're running several different cluster with another EC2
  instance types, using same image. This problem is only reproducing at
  t2.small instances. (We also run c4.large and m4.* clusters)

  Our previous image ran 4.4.0-79-generic, and we see no problem with
  79.

[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services

[Chris Valean]

I took the v4.12 kernel and compiled the LIS daemons from those sources
as well.

Reloading the Data Exchange service, KVP will fail with the below message. This 
is the same as initially reported, so nothing changed in the behavior.
Not sure on the regression part, only up to the point on differences between 
distributions.

KVP failure with v4.12 and 
Jul  6 01:18:55 xenial KVP: read failed; error:9 Bad file descriptor
Jul  6 01:18:55 xenial systemd[1]: hv-kvp-daemon.service: Main process exited, 
code=exited, status=1/FAILURE
Jul  6 01:18:55 xenial systemd[1]: hv-kvp-daemon.service: Unit entered failed 
state.
Jul  6 01:18:55 xenial systemd[1]: hv-kvp-daemon.service: Failed with result 
'exit-code'.

After this error when systemd tries to start KVP again, if I manually do
#systemctl start hv-kvp-daemon.service then the daemon will start just
fine.

  [Hyper-V] LIS daemons fail to start after disable/re-enable VM
  integration services

Bug description:
  Issue description: Hyper-V daemons fail to start after disable/re-
  enable VM integration services.

  Platform: host independent
  Affected daemons - KVP, FCOPY and VSS.

  Distribution name and release: Ubuntu 16.04, Ubuntu 17.04
  Kernel version: 4.11.0-rc7-next-20170421 (for Ubuntu 16.04), 
4.10.0-19-generic (for Ubuntu 17.04)

  Repro rate: 100%

  Steps to reproduce:
  1.Start VM with Guest Services enabled (FCopy daemon starts automatically)
  2.Go to File > Settings > Integration Services, uncheck Guest Services 
and apply (FCopy daemon will stop at this point)
  3.Re-enable Guest Services from VM Settings (Fcopy daemon is not running).
  This is the issue. systemd monitors for the service and if we have the hook 
for the Guest Service, it tries to start the daemon again.
  systemd attempt to start any of the LIS daemons will fail, but manually 
executing the daemon binary, it will start the daemon.

  Additional Info:
  - the steps above can be repro'd with KVP / Data Exchange integration service 
as well.
  - Manually starting hv_fcopy_daemon works fine.
  - other distros (RHEL) does not have this behavior, the LIS daemons are 
started automatically by systemd once we re-enable the integration service.

  On the upstream kernel and the upstream hv daemons, these messages are 
recorded in syslog, once we re-enable the Guest service:
  HV_FCOPY: pread failed: Bad file descriptor
  systemd[1]: hv-fcopy-daemon.service: Main process exited, code=exited, 
status=1/FAILURE
  systemd[1]: hv-fcopy-daemon.service: Unit entered failed state.
  systemd[1]: hv-fcopy-daemon.service: Failed with result 'exit-code'.

  There is a zpool there already (was) with 3TB of data on it. This only

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

[FZ]

Same here, bios version G752VS.306. I also replaced Windows completely
(no dual-boot).

It's really strange since the touchpad was completely dead in both Live
Ubuntu and after installing and upgrading Ubuntu. Yesterday I just
installed Chrome and later run a software update which updated 2 or 3
packages and that's it. Later that night I used the touchpad out of
habit after opening the lid and after a few seconds I remembered that it
wasn't supposed to be working but here it is, fully functional.

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

[Joseph Salisbury]

You may need to run the following from a terminal:

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

If that does not resolve your issue, please mark the bug as "Confirmed"

Title:
  APST quirk needed for Samsung 256GB NVMe drive

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This bug is a follow on from a previously fixed bug.
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184

  The nature of this bug is identical to the previously reported bug, however 
it also affects 256GB drives as well.
  The wording at the start is a bit confusing, as it states that the 256GB 
drive already has a quirk added. Following the trail back a little, however, 
shows that a fix for high power drain was introduced, which then caused the 
NVMe controller lockups and system hangs.

  I am running Ubuntu 16.04 with HWE kernel [4.8.x, yakkety] on a Dell XPS15 
9550 with a Samsung 256GB NVMe SSD.
  This bug commenced with the kernel linux (4.8.0-47.50) yakkety, with the 
specific change found at

[Kernel-packages] [Bug 1701316] Re: Data corruption with hio driver

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.12 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'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

  Mounted sshfs filesystems sometimes prevent suspend

Bug description:
  Using Ubuntu artful with linux-image-4.10.0-26-generic 4.10.0-26.30
  and sshfs 2.8-1. I use "sshfs -o reconnect" and often run gvim against
  a file on an sshfs filesystem.

  Sometimes when I suspend I get:

  Jul  4 20:59:08 xps kernel: [46684.608740] PM: Syncing filesystems ... done.
  Jul  4 20:59:08 xps kernel: [46684.613278] PM: Preparing system for sleep

  ...
  Jul  4 20:59:08 xps kernel: [46704.620711] Restarting tasks ... done.

  ...and the system fails to suspend.

  AFAICT, this is https://bugzilla.redhat.com/show_bug.cgi?id=656992 and
  https://lists.debian.org/debian-kernel/2011/10/msg00412.html has an
  extensive explanation. The corresponding Debian bug was closed long
  ago due to inactivity. It isn't exactly bug 388419 though since that
  is about behaviour after resume, rather than failure to suspend.

  This affects sshfs-fuse, but it sounds like a full fix would be in the
  kernel. I wonder if it's possible to work around in userspace
  packaging in sshfs-fuse, though, by arranging some action in userspace
  before suspend?

  It seems unlikely that this will be addressed any time soon, but it'd be nice 
to keep a bug open in Launchpad so that users can have a single rallying point.

[Kernel-packages] [Bug 1701499] Re: System often freezes or panics if I log in with Dell Dock WD15 connected

[Joseph Salisbury]

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.12 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'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  System often freezes or panics if I log in with Dell Dock WD15
  connected

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I'm using Dell Precision 5520 with Ubuntu 17.04.

  If I first start a Unity session and then connect Dell WD15 USB-C dock
  with an external diplay plugged in, the system detects it properly and
  all the things work flawlessly (ethernet, external keyboard, external
  display, external storage connected to USB on the dock). I can plug-in
  and plug-out the dock multiple times and it just works.

  However if I boot the laptop with the dock already plugged in, first I
  get to the login screen and initially all is ok. Both screens are
  activated, and I can log in using the keyboard connected to the dock.

  When I hit "Enter", both screens go blank for a while, then they turn
  back on and I can see the desktop. A second or maybe two seconds later
  things start falling apart. When I move the mouse pointer a second
  after logging, it is kinda "jumpy", the movement is not smooth. The
  move freezes for a few times. I observed this behaviour only when
  moving the wireless mouse connected to the USB of the laptop. The
  builtin touchpad works smoothly.

  If it was the only issue, this would be a very minor annoyance.
  Sometimes, after a few short mouse pointer freezes the system starts
  working smoothly and all is rock stable from that point. However quite
  often I noticed much worse things happen:

  1. The mouse pointer and everything freezes totally after a few
  seconds from displaying the desktop. It is not possible to switch to
  the console with Ctrl-Alt-F1. This happens in >50% of logins.

  2. Kernel panic.

  I observed this behavior with stable Ubuntu kernel 4.10.0-20, as well
  as 4.11.0 - 4.11.8 (which I'm using now, because 4.11.x seems more
  stable than 4.10.0-x) and also 4.12.rc5 which I tried once.

  Even if everything goes fine, I noticed the following errors printed
  in syslog. I'm not sure if they are related, but they look very iffy
  to me:

You may need to run the following from a terminal:

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

If that does not resolve your issue, please mark the bug as "Confirmed"

[Kernel-packages] [Bug 1701471] Re: package linux-image-4.10.0-26-generic (not installed) failed to install/upgrade: subprocess new pre-installation script returned error exit status 128

[Joseph Salisbury]

You may need to run the following from a terminal:

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

If that does not resolve your issue, please mark the bug as "Confirmed"

When using the following kernel (the default Xenial kernel, aka ga-16.04

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

My Ubuntu is fully updated, but my ELAN touchpad doesn't work.
Next week I will perform a new clean installation, without Windows.
Just one more thing: what is your BIOS version (my is latest available

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

[Kernel-packages] [Bug 1685528] Re: ZFS initramfs mounts dataset explicitly set not to be mounted, causing boot process to fail

[Christopher J. Ruwe]

Are there any recommendations how to proceed with the EOL for yakkety
set? I use zfs clones as inpromptu boot environments when updating and
use ZFS datasets for docker and lxd, so I have a fair amount of
'canmount=none's and 'mountpoint=legacy's. I am reluctant to just c
the script from yakkety over to zesty, but seriously short of better
ideas.

Cheers!

Title:
  ZFS initramfs mounts dataset explicitly set not to be mounted, causing
  boot process to fail

Status in zfs-linux package in Ubuntu:
  Confirmed

Bug description:
  Per https://github.com/zfsonlinux/pkg-zfs/issues/221: the initramfs
  zfs script might overrule canmount and mountpoint options for a
  dataset, causing other mount operations and with them the boot process
  to fail.

  Experienced this with Ubuntu Zesty. Xenial seems to ship with a
  different zfs script for the initrd.

  Work around when it happens: unmount the dataset that should not be
  mounted, and exit the initramfs rescue prompt to resume booting.

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

  [Artful] mlx5e-Introduce RX Page-Reuse

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

Bug description:
  This feature is a Page-Reuse mechanism in non-Striding RQ RX datapath.
  A WQE (RX descriptor) buffer is a page, that in most cases was fully
  wasted on a packet that is much smaller, requiring a new page for
  the next round.

  In this feature, we implement a page-reuse mechanism, that resembles a
  `SW Striding RQ`.
  We allow the WQE to reuse its allocated page as much as it could,
  until the page is fully consumed.  In each round, the WQE is capable
  of receiving packet of maximal size (MTU). Yet, upon the reception of
  a packet, the WQE knows the actual packet size, and consumes the exact
  amount of memory needed to build a linear SKB. Then, it updates the
  buffer pointer within the page accordingly, for the next round.

  Feature is mutually exclusive with XDP (packet-per-page)
  and LRO (session size is a power of two, needs unused page).

Status in docker package in Ubuntu:

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  We run xenial-based Docker container hosts on EC2 with Amazon ECS.
  Recently we refreshed our base image, we started to see frequent
  panic.

  Hosts run Amazon ECS Agent, and the agent automatically creates or
  destroys Docker container based on requests onto ECS cluster.

  I think this crash is caused by Docker-related operations, because
  crashing at cgroups.

  Also, we're running several different cluster with another EC2
  instance types, using same image. This problem is only reproducing at
  t2.small instances. (We also run c4.large and m4.* clusters)

  Our previous image ran 4.4.0-79-generic, and we see no problem with
  79.

You may need to run the following from a terminal:

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

If that does not resolve your issue, please mark the bug as "Confirmed"

[Kernel-packages] [Bug 1701857] Re: Kernel Oops - unable to handle kernel paging request; RIP: 0010:[] [] fput+0x5/0x90

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.12 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'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

[Kernel-packages] [Bug 1701873] Re: Unable to boot with Latest kernel 4.4.0-83 update

[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.

Title:
  Unable to boot with Latest kernel 4.4.0-83 update

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

Bug description:
  Since the update (linux-image-4.4.0-83-generic), I can't boot Ubuntu
  anymore.

  First boot, freeze on desktop with clock freezed (seconds don't increment)
  Second boot, Freeze during boot process
  3rd boot, freezed even earlier in the boot process. 

  Each time I had to manually shutdown my computer by pressing the power
  button.

  If I choose the previous kernel version linux-image-4.4.0-81-generic,
  it works just fine.

  Note that I gathered option using  ubuntu-bug linux, but obviously,
  it's with the previous linux kernel, the one that works. So everything
  should be accurate BUT the kernel version.

  Testing wireless speed with RT-87U 802.11ac router shows that the
  speed is only 27.3 megabits per second which is very low for an
  802.11ac card:

  For comparison, on the same network (from the same distance to the

[Kernel-packages] [Bug 1701316] Re: Data corruption with hio driver

[Peter Sabaini]

Indeed this issue started after upgrading to 4.10.0-26-generic. We've
been using 4.8.0-34-generic previously, and didn't see that issue there.

The hio driver is not present upstream, it's been included in xenial
with Bug #1603483.

Also, we've had consistency issues with this driver before (cf. Bug
#1646643), but afaics the patches from that bug are included in
4.10.0-26-generic

  ---Problem Description---

  On a KVM guest installed to a multipath root device, the kdump kernel fails 
to mount the root file system.  This error does not occur in a similar guest 
installed to a single path device.
   
  Full console output of the kdump failure is attached.  These messages from 
the output may be relevant:

  Begin: Loading multipath modules ... Success: loaded module dm-multipath.
  done.
  Begin: Loading multipath hardware handlers ... Failure: failed to load module 
sc
  si_dh_alua.
  Failure: failed to load module scsi_dh_rdac.

  ---Steps to Reproduce---
   - Install Ubuntu 16.04.1 to a muiltpath target disk
  - Install kdump-tools package
  - Configure kexec-tools to reserve sufficient RAM for the kdump kernel to 
load (I use 512MB) in /etc/default/grub.d/kexec-tools.cfg
  - Run update-grub
  - Reboot
  - Initiate a system crash using "echo c > /proc/sysrq-trigger"

  Yes, I recreated the guest with its correct multipath lun
  configuration.  I have also attached the guest XML to this bug.

  > Besides that could you please let us know:
  >  - is the multipath the system's root? I mean / is installed/mounted on the

  Yes, the guest has only one disk.  That disk is actually a LUN from a
  fiber channel storage device with two paths on the host side.  I have
  passed through both paths to the guest, so the multipath nature of the
  target disk is known to the guest.

  In other words, the guest sees a multipath device and is using it as a
  multipath device.  The root file system is called /dev/mapper/mpatha-
  part2 on the guest.

  >  - how did you attach the device to the guest?

  Each FC LUN path on the host is mapped to a virtio-scsi controller on
  the guest using LUN passthrough.  (See the guest XML for details on
  this.)

  That would smell like an out of memory condition that is alleviated

No, we're not currently aware of any code changes that would cause the
behavioral change that is reported in the bug. Now that we have the
specific kernel version of the HWE kernel, John Johansen can look into
possible causes for the change.

[Kernel-packages] [Bug 1702323] Re: update-initramfs hangs

[Max Keogh]

Hi,
I'm in a loop. I try to run 'apport-collect 1702323' as instructed and I get a 
message saying I need to run 'apt-get install python-apport'.
I run 'apt-get install python-apport' and I get a message saying dpkg was 
interrupted run 'dpkg --configure -a'
I run 'dpkg --configure -a' and it hangs on 'update-initramfs: Generating 
/boot/initrd.img-4.4.0-83-generic'
It will stay like this forever so I have to crash out of this and an unable to 
do any updates.
Any advice is gratefully welcomed.
Kind regards
Max

  == Comment: #0 - Richard M. Scheller - 2016-12-14 16:50:26 ==

  ---Problem Description---

  On a KVM guest installed to a multipath root device, the kdump kernel fails 
to mount the root file system.  This error does not occur in a similar guest 
installed to a single path device.
   
  Full console output of the kdump failure is attached.  These messages from 
the output may be relevant:

  Begin: Loading multipath modules ... Success: loaded module dm-multipath.
  done.
  Begin: Loading multipath hardware handlers ... Failure: failed to load module 
sc
  si_dh_alua.
  Failure: failed to load module scsi_dh_rdac.
  Failure: failed to load module scsi_dh_emc.
  done.

  Machine Type = 8247-22L Ubuntu 16.04.1 KVM guest 
   
   
  ---Steps to Reproduce---
   - Install Ubuntu 16.04.1 to a muiltpath target disk
  - Install kdump-tools package
  - Configure kexec-tools to reserve sufficient RAM for the kdump kernel to 
load (I use 512MB) in /etc/default/grub.d/kexec-tools.cfg
  - Run update-grub
  - Reboot
  - Initiate a system crash using "echo c > /proc/sysrq-trigger"

  Yes, I recreated the guest with its correct multipath lun
  configuration.  I have also attached the guest XML to this bug.

  > Besides that could you please let us know:
  >  - is the multipath the system's root? I mean / is installed/mounted on the
  > multipath device?

  Yes, the guest has only one disk.  That disk is actually a LUN from a
  fiber channel storage device with two paths on the host side.  I have
  passed through both paths to the guest, so the multipath nature of the
  target disk is known to the guest.

  In other words, the guest sees a multipath device and is using it as a
  multipath device.  The root file system is called /dev/mapper/mpatha-
  part2 on the guest.

  >  - how did you attach the device to the guest?

  Each FC LUN path on the host is mapped to a virtio-scsi controller on
  the guest using LUN passthrough.  (See the guest XML for details on
  this.)

  That would smell like an out of memory condition that is alleviated
  with a smaller number of CPUs allowed for the kernel (so the amount of
  memory associated with per-CPU stuff is less in total).

  Per the bug description, the memory reserved for the crashkernel is
  512MB:

  (In reply to comment #23)
  > - Configure kexec-tools to reserve sufficient RAM for the kdump kernel to
  > load (I use 512MB) in /etc/default/grub.d/kexec-tools.cfg

  That seems low for Power guests/systems. 
  I think it theory is doesn't seem so, but the reality is that _for some 
reason(s)_ we require just too much memory to load and boot a kernel/initramfs 
(either on boot or kdump).

[Kernel-packages] [Bug 1702221] Re: Get spammed by PCIe Bus Error

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.12 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'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

  I run latest Ubuntu 17.04 on VivoBook Pro N752VX notebook

  This pcieport 1c.0 is connected to RTL8192EE PCIe Wireless Network
  Adapter (see lspci_vt.log).

  I can disable this message by adding pci=nomsi kernel parameter, but
  this is not a bug fix, only a workaround. Also after appling this
  parameter wifi connection is quite slow and unstable. On windows 10 I
  get approx ping time 3ms to my wifi router. On Linux ping time is
  min/avg/max 5.548/60.137/261.145 with very good signal strength (see
  iwconfig.log).

[Kernel-packages] [Bug 1702685] Re: No wifi connectivity with kernel 4.4.0-83

[Augustine Souza]

I don't know if this helps but I also have Kubuntu 16.04.2 installed on
the same machine with:

uname -a
Linux aes-Inspiron-15-3567 4.8.0-58-generic #63~16.04.1-Ubuntu SMP Mon Jun 26 
18:08:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

and wifi is working out-of-the-box on that.

If you still want me to test with the kernel you've suggested, could you
please explain how I could install it?

[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services

[Joshua R. Poulson]

This is a regression, we did lots of work a year ago to ensure the
daemons handle bouncing integration services settings.

  Issue description: Hyper-V daemons fail to start after disable/re-
  enable VM integration services.

  Platform: host independent
  Affected daemons - KVP, FCOPY and VSS.

  Distribution name and release: Ubuntu 16.04, Ubuntu 17.04
  Kernel version: 4.11.0-rc7-next-20170421 (for Ubuntu 16.04), 
4.10.0-19-generic (for Ubuntu 17.04)

  Repro rate: 100%

  Steps to reproduce:
  1.Start VM with Guest Services enabled (FCopy daemon starts automatically)
  2.Go to File > Settings > Integration Services, uncheck Guest Services 
and apply (FCopy daemon will stop at this point)
  3.Re-enable Guest Services from VM Settings (Fcopy daemon is not running).
  This is the issue. systemd monitors for the service and if we have the hook 
for the Guest Service, it tries to start the daemon again.
  systemd attempt to start any of the LIS daemons will fail, but manually 
executing the daemon binary, it will start the daemon.

  Additional Info:
  - the steps above can be repro'd with KVP / Data Exchange integration service 
as well.
  - Manually starting hv_fcopy_daemon works fine.
  - other distros (RHEL) does not have this behavior, the LIS daemons are 
started automatically by systemd once we re-enable the integration service.

  On the upstream kernel and the upstream hv daemons, these messages are 
recorded in syslog, once we re-enable the Guest service:
  HV_FCOPY: pread failed: Bad file descriptor
  systemd[1]: hv-fcopy-daemon.service: Main process exited, code=exited, 
status=1/FAILURE
  systemd[1]: hv-fcopy-daemon.service: Unit entered failed state.
  systemd[1]: hv-fcopy-daemon.service: Failed with result 'exit-code'.

Bug description:
  My system is a Dell Vostro 1320 on which I installed the Broadcom wireless 
network driver after I had installed Ubuntu 10.04 LTS.  I received this error 
when I tried to install the "flashplugin-installer" from the Synaptic Package 
Manager. 
  I also tried to run the Flash Player Install from the Adobe  web page and 
that also failed. I selected the "APT for Ubuntu 9.04+" and then pressed the 
"Agree and Install Now" button.

  I expected the Flash player to be installed as a plugin for Firefox
  but it fails to complete.
