[Kernel-packages] [Bug 1753662] Re: [i40e] LACP bonding start up race conditions

[Nobuto Murata]

FWIW, I tried PCI hot-plugging to try another way for faster iterations without 
reboot.
https://paste.ubuntu.com/p/qDVkMcTYPQ/

However, the issue wasn't reproducible with hot-plugging. Rebooting is
the easiest reproduction so far.

Title:
  [i40e] LACP bonding start up race conditions

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

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.

[Kernel-packages] [Bug 1763202] Re: Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

I should have added, on the Lenovo the cable goes straight into the
notebook (it has an HDMI port) while with the XPS 13 I need to use a
Thunderbold adapter for attaching the HDMI cable.

  When I try to attach an external monitor via an HDMI cable the monitor

  attach two monitors (one via HDMI, one with DisplayPort) only the

  This made me think if this is really a bug in the software. I saw people

4.4 kernel using the Artful configs didn't make much difference.

I will let stock 4.4 and 4.13 hwe run just to make sure to know the

  Hello Canonical,

  Could you please include the following patch in Bionic?
  --

  When setting up a CPU, we "push" (activate) a pool VP for it.

  However it's an error to do so if it already has an active
  pool VP.

  This happens when doing soft CPU hotplug on powernv since we
  don't tear down the CPU on unplug. The HW flags the error which
  gets captured by the diagnostics.

  Fix this by making sure to "pull" out any already active pool
  first.

Using a script to write MSR isn't a solution.

I wrote a patch [1] to disable C6 directly inside the kernel, but
apparently users are not happy about that.

Since it's the same one as LP: #1690085, we can mark this one as a dupe.

  Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

Status in linux package in Ubuntu:

Bug description:
  I have an X1 Carbon 6th Gen. (Intel Core i7 8th Gen, 16 GB RAM, 512 GB
  SSD).

  When I try to attach an external monitor via an HDMI cable the monitor
  receives no signal. Similarly, when I use the Thunderbold dock and
  attach two monitors (one via HDMI, one with DisplayPort) only the
  monitor attached with DisplayPort works; the monitor attached with
  HDMI stays black.

  This made me think if this is really a bug in the software. I saw people 
describing this issue with Windows installed; the solution was to hit a special 
key combination. Unfortunately, the multimedia keys all not all functional, 
specifically the F7 key, which seems to meant for "activate external monitor", 
has no function.

[Kernel-packages] [Bug 1725859] Re: zfs frequently hangs (up to 30 secs) during sequential read

[Colin Leavett-Brown]

Hello Colin,
  Thank you for responding. To Answer your questions:
  1. I have two external drives, sdb and sdc, in USB 3  Orico enclosure. The 
drives are mirrored.
  2. Atom D525 with 4GiB RAM. The attached screenshot shows "vmstat 5 5" output 
while VLC is playing a movie. It shows 1.5GiB of free memory, no swap used.
  3. Screenshot also shows output from "iostat -mx", and that I manually set 
the spl_kmem_cache_slab_limit to zero as suggested.

  I played a movie which paused repeatedly for 30 seconds and one time
for several minutes. When the pause occurs, VLC is completely hung until
the requested I/O completes. The end of pause is heralded by the I/O
activity LED on the drive enclosure.

  I want to emphasize/re-iterate a couple of points from my original post:
  1. This is not a VLC problem. I can recreate the problem with any app (cp, 
rsyn, etc) that reads sequentially from the ZFS file system.
  2. I do not believe this is a drive/latency problem: I can dd the content of 
sdb and sdc (to /dev/null) without any hang.

  Regards, Colin.

** Attachment added: "spl_kmem_cache_slab_limit, vmstat, and iostat -mx"

  I have an Acer 5820T laptop and am trying to get internet connections
  working both Wifi and Ethernet.

  I have set up the computer as dual boot Lucid 10.04 and Windows 7.  I
  should note that I had to send back the laptop to Acer THREE (3) times
  to replace the hard drive. On the 3rd replacement, Acer updated BIOS
  to 1.18. I have been following the fixes on the various forums.

  The only way I could get the ethernet to work was to install the
  2.6.35-7 kernel.  So, I now have ethernet working  (Atheros AR8151
  AtherosPCI-E)  I tried other fixes suggested but this is the only one
  that would work.

  Next I tried to update the Broadcom 802.1 Drivers  using
  Administration-Hardware Drivers. But I get the error that it is not
  compatible with the 2.6.35 Kernel hence the bug report.

[Kernel-packages] [Bug 1753346] Re: AMD Ryzen 7 1800X system (Dell Inspiron 5675) randomly freezes

[Pragnesh Sampat]

I used Zenstates-Linux from Kai-Heng Feng's reference to
https://bugzilla.kernel.org/show_bug.cgi?id=196683 and things have been
much stabler, I don't think I have seen a freeze since then.

https://github.com/r4m0n/ZenStates-Linux

I have been updating all the while and rebooting, so hard to tell if
something else got picked up, but I suspect the C6 disable did the
trick.  At some  point, I might try enabling it back again, maybe after
the 18.04 release.

At this point, not sure if you want to keep this bug open, whatever
works for you guys.

Bug description:
  This is happening every day or so.  I cannot see anything in the
  kern.log or syslog that give me a clue on where/what the issue might.
  I was using Ubuntu 17.10 earlier and upgraded to Ubuntu 18.04 on
  3/3/2018, since I thought kernel 4.15 might have better support for
  the ryzen 7 and also maybe amdgpu for the radeon 580 might be newer.
  I have removed most external devices except for networking and HDMI
  and audio out.

  Attached a tarball of info, although I believe that since I used
  'ubuntu-bug linux' command, the information might be duplicated,
  apologize for any extra attachments.

Bug description:
  [Impact]
  Crash dump support doesn't work by default on any known arm64 platform. Users 
have to figure out working incantations for the crashkernel= parameter and the 
parameters passed to the crash-dump kernel themselves and manual edit 2 
different config files.

  [Test Case]
  Using either a Centriq 2400 or a Cavium ThunderX CRB (these platforms are 
known to support crashdump), and with a kernel >= 4.13 (xenial-ga did not 
support crashdump):

  sudo apt install kdump-tools
  (reboot, so crashkernel= is added to the kernel commandline)
  echo c | sudo tee /proc/sysrq-trigger

  Crash dump should occur, with artifacts collected in /var/crash.

  If you want to verify that the dump is usable, install the
  corresponding linux-image--dbgsym package and run:

  sudo crash /usr/lib/debug/boot/vmlinux-
  /var/crash//dump.

  crash should successfully load, placing you at a "crash>" prompt. At that 
prompt, you can issue the 'bt' command to see a backtrace.
  Note: you need crash from zesty (7.1.8-1ubuntu1) or later.

  [Regression Risk]
  = Kernel =
  3 patches here touch code outside of arch/arm64/:

  memblock: add memblock_clear_nomap()
  This adds a new function with no callers, so regression risk is negligible.
  (A later patch adds a call to it under arch/arm64/).

  memblock: add memblock_cap_memory_range()
  This refactors some of the code in memblock_mem_limit_remove_map() into a new 
function. The only existing caller of memblock_mem_limit_remove_map() is under 
arch/arm64/, so the regression risk outside of arm64 is negligible.

  efi/libstub/arm*: Set default address and size cells values for an empty dtb
  Because this code is for EFI platforms that support device-tree, it is 
de-facto ARM-specific (as noted in the patch title).

  For arm64, we have mitigated the risk by explicit regression testing on 
several platforms:
   - Qualcomm QDF2400
   - Cavium ThunderX CRB1S
   - HP m400 (X-Gene)
   - HiSilicon D05 (Hi07)

  = kexec-tools =
  == zesty ==
  For zesty, 10 patches are required to add kdump support.

  0001-kexec-extend-the-semantics-of-kexec_iomem_for_each_l.patch:
  This modifies a function used on armhf & x86. The description explains the 
change, and why it does not impact those archs:

  -
  The current users of kexec_iomem_for_each_line(), arm, sh and x86, will not
  be affected by this change because
  * arm
    The callback function only returns -1 or 0, and the return value of
    kexec_iomem_for_each_line() will never be used.
  * sh, x86
    The callback function may return (-1 for sh,) 0 or 1, but always returns
    1 once we have reached the maximum number of entries allowed.
    Even so the current kexec_iomem_for_each_line() counts them up.
    This change actually fixes this bug.
  -

  0002-kexec-generalize-and-rename-get_kernel_stext_sym.patch:
  This generalizes a function that was duplicated by arm & x86 and makes it 
common so arm64 can use it.

  The remaining 8 of these only touch code in kexec/arch/arm64, so
  regression risk for other architectures is negligible.

  Finally, I have tested this update on both i386 and amd64 VMs. i386
  crashes do not currently work in zesty (filed LP: #1699874), and my
  test results show no change there. amd64 worked before, and continues
  to work with these changes.

  == yakkety ==
  Since yakkety is based on an older upstream, 6 additional patches are 
required:

  arm-fix-get_kernel_stext_sym-to-close-its-file.patch:
  This is a cleanup patch, cherry-picked because it allows later patches to 
apply w/o backporting. ARM-specific.

  kexec-add-max_size-to-memory_ranges.patch:
  Adds a new element to struct, to be used by later commits.

  kexec-add-generic-helper-to-add-to-memoryq_regions.patch,
  kexec-add-mem_regions-sorting-implementation.patch,
  kexec-add-helper-to-exlude-a-region-from-a-set-of-me.patch,
  kexec-fix-mem_regions_sort.patch:
  These patches only add new functions, which will be used by later patches.

  

[Kernel-packages] [Bug 1763202] Re: Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

[Peter Bittner]

I must correct my findings re the XPS 13 Developer Edition. (I'm sorry!)

The external monitor works fine. It really seems to be specific to the
Lenovo hardware.

  Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

Status in linux package in Ubuntu:

Bug description:
  I have an X1 Carbon 6th Gen. (Intel Core i7 8th Gen, 16 GB RAM, 512 GB
  SSD).

  When I try to attach an external monitor via an HDMI cable the monitor
  receives no signal. Similarly, when I use the Thunderbold dock and
  attach two monitors (one via HDMI, one with DisplayPort) only the
  monitor attached with DisplayPort works; the monitor attached with
  HDMI stays black.

  This made me think if this is really a bug in the software. I saw people 
describing this issue with Windows installed; the solution was to hit a special 
key combination. Unfortunately, the multimedia keys all not all functional, 
specifically the F7 key, which seems to meant for "activate external monitor", 
has no function.

  Hello Canonical,

  Could you please include the following patch in Bionic?
  --

  When setting up a CPU, we "push" (activate) a pool VP for it.

  However it's an error to do so if it already has an active
  pool VP.

  This happens when doing soft CPU hotplug on powernv since we
  don't tear down the CPU on unplug. The HW flags the error which
  gets captured by the diagnostics.

  Fix this by making sure to "pull" out any already active pool
  first.

I'm not positive when it happened.  Or if I can easily reproduce.  I'll see
about running the latest mainline kernel and see if it fixes things.

Re: [Kernel-packages] [Bug 1763177] Re: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008

[BertN45]

I can't reproduce the problem on Linux 4.15.0-13. I reinstalled 
Lollypop, but no crashes. Only a completely other crash of Lollypop 
itself, every time I change the album art.

I think, it might be one of those crashes, that occur once a week or so.

Sorry, I keep looking.

[Kernel-packages] [Bug 1763202] Re: Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

[Peter Bittner]

> Did this issue start happening after an update/upgrade?

I can't tell exactly. The system is just a week old, but I recall that
there has been a kernel upgrade. HDMI had some issues (i.e. wouldn't
connect) via Lenovo's docking station last week, it worked today though
when connected to the notebook's HDMI port directly.

I've tried with my somewhat aged (but okay) LG Flatron M2380D-PZ
monitor, and there is some trouble:

- The monitor is apparently detected when (the HDMI cable is attached and) the 
monitor is turned on:
- The second monitor shows up in System Settings > Devices > Displays for about 
a second. Before that the notebook screen turns black for about half a second.
- Then the second monitor disappears from the Settings again, and the external 
monitor shows "No Signal"

That is an issue only since Ubuntu 18.04 (I can't tell whether it's
related to a specific kernel), because the monitor used to work with my
Dell XPS 13 Developer Edition, which is running the very same
configuration of Ubuntu (18.04 LTS developer version) and behaves
similarly now, until Ubuntu 17.10 not too long ago.

I'm a bit reluctant building the latest kernel. If it's really really
important I may give it a shot.

  Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

Status in linux package in Ubuntu:

Bug description:
  I have an X1 Carbon 6th Gen. (Intel Core i7 8th Gen, 16 GB RAM, 512 GB
  SSD).

  When I try to attach an external monitor via an HDMI cable the monitor
  receives no signal. Similarly, when I use the Thunderbold dock and
  attach two monitors (one via HDMI, one with DisplayPort) only the
  monitor attached with DisplayPort works; the monitor attached with
  HDMI stays black.

  This made me think if this is really a bug in the software. I saw people 
describing this issue with Windows installed; the solution was to hit a special 
key combination. Unfortunately, the multimedia keys all not all functional, 
specifically the F7 key, which seems to meant for "activate external monitor", 
has no function.

[Kernel-packages] [Bug 1711407] Re: unregister_netdevice: waiting for lo to become free

[Dan Streetman]

Hi Jiri,

no the "Won't Fix" is only for the Zesty release, as that's EOL now.

I actually have a test kernel building in the ppa:
https://launchpad.net/~ddstreet/+archive/ubuntu/lp1711407/+packages

it's version 4.13.0-38.43+hf1711407v20180412b2; it hasn't finished
building yet, probably will take another ~4 hours or so (building the
kernel in ppas is sloow)

this patch isn't quite finished, I still have to redo the netns cleanup
workqueue because the cleanup work can now hang (indefinitely) so it
can't be a single-threaded workqueue with the same work queued.  But, it
should at least verify if it works around the container create/destroy
hangs.

  [Impact]

  When shutting down and starting containers the container network
  namespace may experience a dst reference counting leak which results
  in this message repeated in the logs:

  unregister_netdevice: waiting for lo to become free. Usage count =
  1

  This can cause issues when trying to create net network namespace and
  thus block a user from creating new containers.

  [Test Case]

  See comment 16, reproducer provided at https://github.com/fho/docker-
  samba-loop

Re: [Kernel-packages] [Bug 1708922] Re: uvcvideo module does not work with Dell XPS 12 webcam

[Reinhard Tartler]

If you can, please file a separate bug for uvcvideo with a stacktrace. Then
please link those bugs

The easiest way is probably by using apport on the crash file, I guess.

So i removed virtualbox and guest dkms and installed Mainline
4.16.1-041601 and i conclude

'kernel-bug-exists-upstream'

The filebot window as well as the nautilus window that i drag the files from

The system and Desktop is still responsive (but sometimes was before as well

Re: [Kernel-packages] [Bug 1708922] Re: uvcvideo module does not work with Dell XPS 12 webcam

[emk2203]

Original reporter here. I am willing to assist wherever I can, but I
reported chiefly because I cannot debug or investigate of my own.

Regarding the cheese issue, the exact same issue arises when just using
uvcvideo, so it is definitely something passed on from the driver.

Title:
  uvcvideo module does not work with Dell XPS 12 webcam

Status in cheese package in Ubuntu:
  Confirmed
Status in ffmpeg package in Ubuntu:
  Incomplete
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  uvcvideo: Found UVC 1.00 device Integrated Webcam (0bda:5716) from
  Dell XPS 12 laptop (9Q33 version) does not work properly for several
  versions of the kernel now.

  guvcview nor cheese both show the issue, so it's the uvcvideo driver.
  Starting at 640x480 and higher resolutions, parts of lower half of
  video flickers / don't show image.

  Error messages:
  V4L2_CORE: (jpeg decoder) error while decoding frame
  V4L2_CORE: (jpeg decoder) Ignoring empty buffer
  V4L2_CORE: Error - Couldn't decode frame

  VLC seems to use another driver AND DOES NOT SHOW issue.

[Kernel-packages] [Bug 1762468] Re: Cryptoswap not working in Bionic

[Martin D. Weinberg]

Some good and bad news: I have been testing this in a running Gnome 3
environment.  I decided to start testing on console.  On console, all
kernels seem to fail using crypt swap.  This suggests to me that failure
must depend on current memory usage, dirty ratio, or some such runtime
condition.

However, the good news, I have kernel messages on console.  I'm
attaching a screen shot, since none of them get written to syslog.  A
typical message is: task dm_write:xxx blocked for more than 120 seconds

There are no problems when not using dm_crypt for swap, i.e. 'normal'
swap.

  Cryptoswap not working in Bionic

Bug description:
  I have cryptoswap set up both with the 2 GB default swap file and an 8
  GB swap partition with 8 GB of ram.  However, the system does not use
  this swap when it should.  For example, if I run a little test code
  which attempts to allocate 10 GB of memory in 1 GB chuncks, the system
  hangs with no obvious use of swap.  E.g. running top shows no swap use
  before the hang.  However, if I replace cryptoswap by standard swap,
  it works as expected: allocates the requested memory and exits, using
  swap.  Of course, my disk is slow, so this takes some time but it does
  work.

  I originally noticed this problem when compiling a very large
  application.  The system would hang on ld.  I've checked hardware
  using memtest and stress.  No problems.  This took me days to track
  down but I'm 99% certain now that the problem is with cryptoswap.  If
  I compile with cryptoswap: hang.  If I compile with standard swap: no
  problem.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[John Lindgren]

I tested the following mainline packages:

linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb
linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb
linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

Still unbootable except in recovery mode.

The only difference, 4.16 generates new messages about missing firmware
that neither 4.13 nor 4.15 generated:

  Hello Canonical,

  Could you please include the following patch in Bionic?
  --

  When setting up a CPU, we "push" (activate) a pool VP for it.

  However it's an error to do so if it already has an active
  pool VP.

  This happens when doing soft CPU hotplug on powernv since we
  don't tear down the CPU on unplug. The HW flags the error which
  gets captured by the diagnostics.

  Fix this by making sure to "pull" out any already active pool
  first.

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

[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
v4.16 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:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

Title:
  Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have an X1 Carbon 6th Gen. (Intel Core i7 8th Gen, 16 GB RAM, 512 GB
  SSD).

  When I try to attach an external monitor via an HDMI cable the monitor
  receives no signal. Similarly, when I use the Thunderbold dock and
  attach two monitors (one via HDMI, one with DisplayPort) only the
  monitor attached with DisplayPort works; the monitor attached with
  HDMI stays black.

  This made me think if this is really a bug in the software. I saw people 
describing this issue with Windows installed; the solution was to hit a special 
key combination. Unfortunately, the multimedia keys all not all functional, 
specifically the F7 key, which seems to meant for "activate external monitor", 
has no function.

[Kernel-packages] [Bug 1763177] Re: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008

[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
v4.16 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.

Bug description:
  Hello Canonical,

  Could you please include the following patch in Bionic?
  --

  When setting up a CPU, we "push" (activate) a pool VP for it.

  However it's an error to do so if it already has an active
  pool VP.

  This happens when doing soft CPU hotplug on powernv since we
  don't tear down the CPU on unplug. The HW flags the error which
  gets captured by the diagnostics.

  Fix this by making sure to "pull" out any already active pool
  first.

  Whenever I try to shutdown or reboot the system while the internal
  wifi card is enabled, the systems hangs (system does not switch to
  command line mode, only possible to reboot using Syrq-Key+B, even
  Sysrq+O does not work). When I disable the wifi card using network
  manager before shutting down it works fine. The system runs in UEFI
  mode.

[Kernel-packages] [Bug 1711407] Re: unregister_netdevice: waiting for lo to become free

[Jiri Horky]

Hi Dan,

how should I read that it got to "Won't fix" state? No more time to
debug it?

Thanks
Jirka H.

  This is a "continuation" of bug 1403152, as that bug has been marked
  "fix released" and recent reports of failure may (or may not) be a new
  bug.  Any further reports of the problem should please be reported
  here instead of that bug.

  [Impact]

  When shutting down and starting containers the container network
  namespace may experience a dst reference counting leak which results
  in this message repeated in the logs:

  unregister_netdevice: waiting for lo to become free. Usage count =
  1

  This can cause issues when trying to create net network namespace and
  thus block a user from creating new containers.

  [Test Case]

  See comment 16, reproducer provided at https://github.com/fho/docker-
  samba-loop

  Hey,

  we are currently debugging an issue with Scope [1] where the
  initialization of the used tcptracer-bpf [2] leads to a kernel oops at
  the first call of `bpf_map_lookup_elem`. The OS is Ubuntu Xenial with
  kernel version `Ubuntu 4.4.0-119.143-generic 4.4.114`. `4.4.0-116.140`
  does not show the problem.

[Kernel-packages] [Bug 1704799] Re: iwlwifi: 8260: missing iwlwifi-8000C-{22..30}.ucode firmware

[Edmund Laugasson]

... still using 64-bit Linux Mint 18.3 MATE which is based on Ubuntu 18.04 LTS. 
Updated linux-firmware package manually. Originally Ubuntu 16.04 LTS has 
linux-firmware 1.157.17
Would be thankful to know, which firmware version works with which kernel 
version.

[Kernel-packages] [Bug 1763454] Re: bpf_map_lookup_elem: BUG: unable to handle kernel paging request

[Alban Crequy]

I'm taking a guess at the cause of this kernel panic:

commit c131187db2d3fa2f8bf32fdf4e9a4ef805168467 was backported from
upstream kernel into the Ubuntu kernel.

But this part was not backported:

--- a/kernel/bpf/verifier.c
+++ b/kernel/bpf/verifier.c
@@ -4213,6 +4216,8 @@ static int adjust_insn_aux_data(struct bpf_verifier_env 
*env, u32 prog_len,
memcpy(new_data, old_data, sizeof(struct bpf_insn_aux_data) * off);
memcpy(new_data + off + cnt - 1, old_data + off,
   sizeof(struct bpf_insn_aux_data) * (prog_len - off - cnt + 1));
+   for (i = off; i < off + cnt - 1; i++)
+   new_data[i].seen = true;
env->insn_aux_data = new_data;
vfree(old_data);
return 0;

The likely reason for omission is that the Ubuntu kernel does not have
this function in kernel/bpf/verifier.c, so there was no place to apply
the patch snippet above. In upstream kernel, adjust_insn_aux_data() is
called from fixup_bpf_calls() and that function was not in
kernel/bpf/verifier.c yet in Ubuntu kernel.

However, semantically, the patch should have been applied in
kernel/bpf/syscall.c, which is the file where fixup_bpf_calls() was
located before it got refactored by commit e245c5c6a5656.

As a result, the BPF_CALL instruction is mistakenly considered not seen
by the verifier so the BPF instructions for array_map_lookup_elem() are
not emitted.

  status appears to hang, no output for 10 seconds.

  strace reveals that without a /dev/zfs the tools wait for it to appear
  for 10 seconds but do not provide a command line switch to disable or

  Since at least kernel 4.4.0-116, every invocation of `sysctl -a`
  results in kernel logs similar to the following:

  % sysctl -a &>/dev/null; dmesg -T | tail -8
  [Wed Mar 14 00:06:36 2018] sysctl_ibrs_enabled = 0, sysctl_ibpb_enabled = 0

  The output varies with the number of CPUs.

  After digging a bit, it turns out this is triggered upon every read of
  `kernel.ibrs_dump`:

  % for i in {1..3}; do sysctl kernel.ibrs_dump; dmesg -T | tail -8; echo; 
sleep 1; done

  Those tests were against an EC2 instance running Ubuntu 4.4.0-116.140-generic 
4.4.98 per /proc/version_signature

  Normally this would not be the biggest concern but we have tooling
  that gathers instance info on a schedule, including sysctl output,
  thus resulting in the kernel ring buffer being full of nothing but
  said output in most cases and hindering live troubleshooting as a
  result.

  kernel version `Ubuntu 4.4.0-119.143-generic 4.4.114`. `4.4.0-116.140`

  I updated kernel to 4.13.0-37-generic, and after reboot, it freezes on
  the kde login screen. Even sysrq keys does not work. I rebooted again,
  and be able to enter password, then it freezes again on plasma loading
  screen. I finally selected 4.13.0-36-generic kernel from grub, and my
  computer booted normally. I guess there was a kernel panic, but it
  didn't show on screen, nor in system logs, or I cannot find it.

[Kernel-packages] [Bug 1749715] Re: general protection fault in zfs module

[Simon Déziel]

@Colin, sorry for the delay, I just checked and
/sys/module/spl/parameters/spl_taskq_thread_dynamic defaults to 0
already.

That said, the issue happens only occasionally. Since I first reported
it, there was only one other event during which it occurred several
times in a row (between 2018-03-14 and 2018-03-15). I rebooted the VM
and have yet to see it happen again. I still have the logs from those if
that could be of any use to you.

Thanks for taking such good care of ZoL for Ubuntu!

[Kernel-packages] [Bug 1704799] Re: iwlwifi: 8260: missing iwlwifi-8000C-{22..30}.ucode firmware

[Edmund Laugasson]

somehow I could once with kernel 4.16.2 and linux-firmware 1.173 get it
working:

kernel: iwlwifi :04:00.0: loaded firmware version 36.e91976c0.0 op_mode 
iwlmvm
kernel: iwlwifi :04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, 
REV=0x208


...but could not reproduce it and rest of times could not get working. Tried to 
purge original linux-firmware and reinstalled, also deleted all manually added 
firmware packages but still no results.

Currently working with 4.15.17 and linux-firmware 1.173:
kernel: iwlwifi :04:00.0: loaded firmware version 34.0.1 op_mode iwlmvm
kernel: iwlwifi :04:00.0: Detected Intel(R) Dual Band Wireless AC 8260,

[Kernel-packages] [Bug 1721589] Re: same mount-point after rename dataset

[davidak]

It was about 200 datasets or so and we renamed them through a script
with the rename command line program. Nothing special.

I don't work at that company anymore, so i can't reproduce it or look up
the exact command used.

  Those tests were against an EC2 instance running Ubuntu 4.4.0-116.140-generic 
4.4.98 per /proc/version_signature

  Normally this would not be the biggest concern but we have tooling
  that gathers instance info on a schedule, including sysctl output,
  thus resulting in the kernel ring buffer being full of nothing but
  said output in most cases and hindering live troubleshooting as a
  result.

[Kernel-packages] [Bug 1762468] Re: Cryptoswap not working in Bionic

[Joseph Salisbury]

Thanks for finding the mainline 4.10 does not have the bug and 4.11
final does.  Can you also test v4.11-rc1, so we can find which release
candidate introduced the bug?

Title:
  Cryptoswap not working in Bionic

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

Bug description:
  I have cryptoswap set up both with the 2 GB default swap file and an 8
  GB swap partition with 8 GB of ram.  However, the system does not use
  this swap when it should.  For example, if I run a little test code
  which attempts to allocate 10 GB of memory in 1 GB chuncks, the system
  hangs with no obvious use of swap.  E.g. running top shows no swap use
  before the hang.  However, if I replace cryptoswap by standard swap,
  it works as expected: allocates the requested memory and exits, using
  swap.  Of course, my disk is slow, so this takes some time but it does
  work.

  I originally noticed this problem when compiling a very large
  application.  The system would hang on ld.  I've checked hardware
  using memtest and stress.  No problems.  This took me days to track
  down but I'm 99% certain now that the problem is with cryptoswap.  If
  I compile with cryptoswap: hang.  If I compile with standard swap: no
  problem.

[Kernel-packages] [Bug 1761751] Re: Black screen on 18.04 + AMD RX460

[Joseph Salisbury]

I built the first test kernel, up to the following commit:
6a5e05a47b6cb8e59bfad351444322b1e4012326

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1761751

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

  Black screen on 18.04 + AMD RX460

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Bionic:
  In Progress

Bug description:
  I've been running 16.04 + hwe kernel 4.15 for a while now and recently
  I'm now having a black screen instead. I've also tried an 18.04 daily
  live USB stick, which has the same issue.

  It probably started during an upgrade this week or last week. As a
  start I'm blaming the Linux kernel since booting a 4.13 kernel works
  just fine.

  Known faulty kernel versions are:
   * linux-image-4.15.0-041500-generic (mainline kernel),
   * linux-image-4.16.0-041600-generic (mainline kernel),
   * linux-image-4.15.0-13-generic (Ubuntu kernel),
   * whatever comes with 18.04 daily live USB stick as of 20180404.

  Not sure how to best collect logs and system information for you since
  I'm not used to debugging black screens, so I'm just attaching lspci
  as a start.

  EDIT: Workaround found by adding "amdgpu.dc=0" to kernel boot
  parameters.

[Kernel-packages] [Bug 1722261] Re: deadlock in mount umount and sync

[Colin Ian King]

Is this still and issue for you?

You may be able to identify the processes that are causing the problem
using the fuser command, e.g. on mounted zfs file system /poolname use:

fuser -vm /poolname

maybe that helps.

Title:
  initramfs-zfs should support misc /dev dirs

Status in zfs-linux package in Ubuntu:
  Confirmed

Bug description:
  Right now 'zfs-initramfs', i.e. /usr/share/initramfs-tools/scripts/zfs
  does not support any other directory than /dev for "zpool import ...".
  Therefore even if a pool gets created from a different directory like
  /dev, say /dev/disk/by-id or /dev/chassis/SYS on next reboot /dev will
  be used and thus zpool status will show the /dev/sd* etc. on
  successful import. Beside that now a user does not see the original
  names used in "zpool create ..." the unstable names like "/dev/sd*"
  are shown, which is explicitly NOT recommended.

  The following patch introduces the "pseudo" kernel param named "zdirs"
  - a comma separated list of dev dirs to scan on import - which gets
  used by /usr/share/initramfs-tools/scripts/zfs to honor it.
