[Kernel-packages] [Bug 1638779] Re: [arm] Missing AHCI driver in Ubuntu Xenial Installer for ARM

[Thang Nguyen]

Why the Ubuntu Server installer always require the CD-ROM detection to continue 
installation?
In other OSes such as SUSE, CentOS, Fedora, ... I can install without the need 
of CD-ROM. Just dd-ing the ISO file into a USB key drive and use it for 
installation.

Title:
  [arm] Missing AHCI driver in Ubuntu Xenial Installer for ARM

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Download the media installation ISO file at 
https://www.ubuntu.com/download/server/arm and burn it to a CD-ROM. Then, put 
it into the SATA CD drive to install Ubuntu into Mustang/Merlin boards (XGene 
platform), the Installer does not detect the CD-ROM so it report a dialog with 
below content:
  "Your installation CD-ROM couldn't be mounted. This probably means that the 
CD-ROM was not in the drive. If so you can insert it and try again. Retry 
mounting the CD-ROM?".
  Investigate more on the installer media, I found that the AHCI driver is not 
enabled.
  Below steps I have done to check:
  - Mount ISO file and copy initrd.gz:
   # mkdir mnt
   # mount -o loop ubuntu-16.04.1-server-arm64.iso ./mnt
   # cp ./mnt/install/initrd.gz .
  - Extract initrd.gz:
   # gunzip initrd.gz
   # cpio -id < initrd
  - List the drivers/ata folder
   # ls lib/modules/4.4.0-31-generic/kernel/drivers
  block  gpio  gpu  hid  i2c  input  media  mfd  power  regulator  rtc  usb  
video
  No lib/modules/4.4.0-31-generic/kernel/drivers/ata folder exist.

  Try to check with x86 installer media:
   # ls lib/modules/4.4.0-31-generic/kernel/drivers/
  ata  block  char  firewire  gpio  gpu  hid  hv  i2c  infiniband  input  media 
 mfd  net  parport  pcmcia  power  regulator  rtc  scsi  tty  usb  video
   # lib/modules/4.4.0-31-generic/kernel/drivers/ata/ | grep ahci
  acard-ahci.ko
  ahci.ko
  ahci_platform.ko
  libahci.ko
  libahci_platform.ko

  Can you help to add AHCI support for Ubuntu ARM Media installer?

  Thanks,
  Thang Q. Nguyen

  ZFS 0.7.0 will require new userland tools

Bug description:
  ZFS 0.7.0 has been released: http://list.zfsonlinux.org/pipermail/zfs-
  announce/2017-July/15.html.

  It is important to note it will require an update of the userland
  tools (zpool command). This can be an issue especially for the HWE
  kernel stack if ZFS module versions would bump to 0.7.0 without an
  update of the zfsutils and zfs-initramfs packages.

  Upgraded to zesty about a week ago. Ran into this on latest kernel.

  Did not happen with previous (4.10.0.14.16) kernel. Only after update

  crashes), this is the one I could capture.

[Rex Tsai]

@Nazar Gerasymchuk (troyan3)
Could you provide the output of "uname -a" on your testing kernel? you might 
have installed the version from Ubuntu archive without the fix, but not the deb 
version I built.

  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

  kern.log entries below. Let me know if you need anything else from me.

Bug description:
  The OrangeFS kernel module
  (/lib/modules//kernel/fs/orangefs/orangefs.ko) has been
  available as part of the Linux kernel since version 4.6, but has not
  been compiled as part of the ubuntu kernel-image package or any other
  package for the amd64 and i386 architectures. According to Ubuntu
  Package Search, it is being compiled for the arm64, armhf, and powerpc
  architectures.

  This bug report is to add support for OrangeFS by compiling the
  orangefs module and including it with the all kernel packages >= 4.6.
  This can be done by enabling CONFIG_ORANGEFS_FS as a module in the
  kernel config file.

[Kernel-packages] [Bug 1678477] Re: Kernel has troule recognizing Corsair Strafe RGB keyboard

[Luca Cireddu]

I'm using the keyboard using Ubuntu 17.04 stock kernel with an external, 
independent powered, usb 2.0. It has a 3.0 Ampere power supply, not so big for 
these days, but powerful enough to avoid power problems for this keyboard.
I'm using it for a while, several reboots and power-cycles, and I haven't had 
any error in dmesg, yet.
It seems to confirm that it is a problem of power management on usb ports...

Title:
  Kernel has troule recognizing Corsair Strafe RGB keyboard

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I recently bought a Corsair Strafe RGB keyboard, and while it works
  well when successfully recognized by Ubuntu at boot, that doesn't
  always happen.

  I see messages like this when booting my desktop up:

  [6.619510] usb 3-10: unable to read config index 0 descriptor/all
  [6.619543] usb 3-10: can't read configurations, error -110

  They sometimes repeat at 5-second intervals, culminating on a "can't
  set config #1" message or even "unable to enumerate USB device". This
  happens on the logic that deals with a new USB device being connected,
  so when it doesn't work it never gets to the HID drivers part of the
  code. When it does, hid-generic is quite able to control the keyboard,
  though this message appears on dmesg:

  [6.883811] usbhid 3-10:1.2: couldn't find an input interrupt
  endpoint

  
  From what I have been able to determine, the Corsair Strafe RGB has three 
inputs, with the last one being used as input/output and having something to do 
with the LEDs. It only has a single USB configuration, though I don't know why 
it times out.

  Searching on Google has a lot of people recommending this userspace
  drive to me: https://github.com/mattanger/ckb-next , and I've tried
  it, but it seems to be more about programming lighting effects into
  the keyboard than in controlling its basic operation, which is all I'm
  interested in. Its daemon was supposed to handle that part too, but it
  didn't fix those connection errors on boot.

  I have the following boot parameter set in my kernel, following advice
  from ckb-next's README, but it doesn't see to have an appreciable
  effect on my success rate:

  usbhid.quirks=0x1B1C:0x1B20:0x2448

  ckb-next recommended 0x2408, but I added the HID_QUIRK_MULTI_INPUT
  as well in an attempt to improve things, without success.

  GRUB is always able to correctly identify the keyboard and get it to
  work, too, which makes the fact that the full kernel can't always do
  it a little more frustrating.

  I would be happy to provide any extra information you require on this
  issue.

[Kernel-packages] [Bug 1696154] Re: [17.10 FEAT] Sign POWER host/NV kernels

[Steve Langasek]

One open technical question from the Canonical side: can you confirm
that the POWER firmware implementation will support embedded certificate
chains as part of the vmlinux signature data?  Our existing SecureBoot
signing regime uses an on-line signing key which is chained to a our CA
certificate, and it is the latter that we would normally provide for db.

It appears that the kmodsign tools support embedded certificates in the
signature data, but we would like to confirm that the firmware
implementation is also compatible with this.

Title:
  [17.10 FEAT] Sign POWER host/NV kernels

Status in The Ubuntu-power-systems project:
  In Progress
Status in linux package in Ubuntu:
  In Progress

Bug description:
  Feature Description:

  Sign POWER host and NV kernels with sign-file in anticipation of POWER
  secure boot.  Provide the  associated certificate.  Ideally it would
  be possible to reuse the UEFI shim private key and certificate used to
  sign and verify x86_64 kernels.  More details to follow.  Guest
  kernels will be addressed in a future separate feature request.

  
  Business Case: 

  As a system administrator I want to verify the integrity of my kernels
  so that I can prevent malicious kernels from being executed.

  Use Case:

  Signed POWER kernels will be validated by OPAL as OpenPOWER systems
  boot when keys are properly installed and the system is booted in
  secure mode.

  
  Test Case:

  Sign and install a POWER kernel on an OpenPOWER machine with a
  firmware level that supports secure boot.  Install a PK, distro KEK
  certificat, and distro DB certificate.  Boot the system and verify
  that it will boot the kernel.  Negative tests:  Separately remove the
  signature, install an usigned kernel, and modify the kernel image and
  test that the kernel will not boot.

[Kernel-packages] [Bug 1706891] [NEW] ZFS 0.7.0 will require new userland tools

[Sam Van den Eynde]

Public bug reported:

ZFS 0.7.0 has been released: http://list.zfsonlinux.org/pipermail/zfs-
announce/2017-July/15.html.

It is important to note it will require an update of the userland tools
(zpool command). This can be an issue especially for the HWE kernel
stack if ZFS module versions would bump to 0.7.0 without an update of
the zfsutils and zfs-initramfs packages.

Bug description:
  After the update to the kernel 3.50.22 when I rebooted the computer It only 
displayed some orange vertical lines instead of the login page (image 3), 
moving the mouse up it's point appears (over a black line)(image 5) and moving 
the mouse on the top-right corner the lines became grey(image 4) and clicking 
they became dark grey (the color of the shut-down menu) (image 6). 
  Sometimes instead of the lines it shows the screen as shifted to the right 
(the right half of the screen ison the left and the left part on the 
right)(images 1 and 2 are of two different times I used the computer).
  The same happens with the 3.50.23 kernel. 
  Booting with the 3.50.21 it works fine.

I followed the upstream bug report guidelines but I can't see my report

rejected...

Any idea ?

  I experience a very long boot time, having done an analysis it appears
  that the main problem is the kernel boot time and more specifically
  the time it takes to start its USB subsystem.

  when you look at the dsmg output you can clearly see a gap between 4-78s and 
79-91s, all in the USB sub-process.

Bug description:
  eSATA disks are are not auto mounted when plugged in.  This is because
  udisks uses a heuristic to decide if it should auto mount a drive.
  The heuristic is motivated by the desire to not auto mount internal
  disks/partitions that belong to other operating systems.  The
  heuristic currently makes the assumption that disks connected via a
  usb bus are external, and disks connected with other buses ( sata,
  scsi ) are internal, and thus does not mount them.  This heuristic is
  inherently unreliable as usb disks can potentially be internal, and
  sas/sata disks can be external.  Thus, the heuristic needs to be
  disabled, and all unknown disks need to be auto mounted.  Disks
  detected but left unconfigured at install time should have entries in
  /etc/fstab set to noauto to prevent their being auto mounted.

[Balint Reczey]

Public bug reported:

Please sync crash 7.1.9-1 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
  * Use only available repository pockets in autopkgtest (LP: #1693387)
  * Use isolation-machine in autopkgtest to ensure that the running
kernel has available debug packages in the archive in use
  * Merge from Debian unstable (LP: #1672361).  Remaining changes:
- Build for armhf, ppc64el.
- Minor fixes for live autopkgtest.
  * Merge from Debian unstable (LP: #1672361).  Remaining changes:
- Build for armhf, ppc64el.
- Minor fixes for live autopkgtest.
  * d/p/0001-Fix-for-Linux-4.6-commit-b03a017bebc403d40aa53a092e7.patch :
Fix additional kernel 4.6 issue introduced post-7.1.7 release.
  * d/p/0002-Fix-for-support-of-proc-kcore-as-the-live-memory-sou.patch :
Fix live crash usage failure identified by autopkgtest. This commit was
introduced post-7.1.7 release.
  * Merge from Debian unstable.  Remaining changes:
- Build for armhf, arm64, ppc64el.
- Minor fixes for live autopkgtest.
- debian/tests/live: Redirect gpg stderr to stdout, as that's the only
  known and expected stderr source.
- Simplify ddeb archive requirements.
  * Dropped patches:
- 0001-Fix-for-the-changes-made-to-the-kernel-module-struct.patch
- 0002-Fix-for-the-changes-made-to-the-kernel-module-struct.patch
  * Merge from Debian unstable.  Remaining changes:
- Build for armhf, arm64, ppc64el.
- Minor fixes for live autopkgtest.
- debian/tests/live: Redirect gpg stderr to stdout, as that's the only
  known and expected stderr source.

- 0001-Fix-for-the-changes-made-to-the-kernel-module-struct.patch
- 0002-Fix-for-the-changes-made-to-the-kernel-module-struct.patch
  * d/p/0002-Fix-for-the-changes-made-to-the-kernel-module-struct.patch:
Cherry-pick additional crash commit needed to fix issues related to
kernel commit 8244062e. (LP: #1564487)
  * d/p/0002-Fix-for-the-changes-made-to-the-kernel-module-struct.patch:
Cherry-pick additional crash commit needed to fix issues related to
kernel commit 8244062e. (LP: #1564487)
  * debian/tests/live: Use the new ddebs.ubuntu.com key C8CAB6595FDFF622
  * d/p/0001-Fix-for-the-changes-made-to-the-kernel-module-struct.patch:
Fix launch failure on kernel newer than 4.4 (LP: #1555244)
  * Merge from Debian unstable.  Remaining changes:
- Build for armhf, arm64, ppc64el.
- Minor fixes for live autopkgtest.
- debian/tests/live: Redirect gpg stderr to stdout, as that's the only
  known and expected stderr source.
- Simplify ddeb archive requirements.
  * Dropped patches:
- 4_2_support.patch

The last delta consisted of fixing autopkgtest, building on more architectures
and one one line to d/rules which is obsolete. The former changes are now
integrated in Debian.

Changelog entries since current artful version 7.1.8-1ubuntu2:

crash (7.1.9-1) unstable; urgency=medium

  * Patch from Balint Reczey : Build crash on all Linux
architectures (Closes: #763856, #757450)

  * Patch from Balint Reczey : Continuous integration
tests can fail due to missing packages for the running kernel and missing
*-updates packages (Closes: #869367)

  * Fixes to address three gcc-7.0.1 compiler warnings that are generated when
building with "make warn".  The warning types are "[-Wnonnull]" in
filesys.c, and "[-Wformat-overflow=]" in kernel.c and cmdline.c.

  * Fix for the PPC64 "mach -o" option to update the OPAL console buffer size
from 256K to 1MB, based upon the latest skiboot firmware source.

  * Fix for the "mod -[sS]" option to prevent the erroneous reassignment of
one or more symbol values of a kernel module.  Without the patch, when
loading a kernel module, a message may indicate "mod: : last
symbol:  is not _MODULE_END_?" may be displayed, and one
or more symbols may be reassigned an incorrect symbol value.  If none of
the erroneous symbol value reassignments are beyond the end of the
module's address space, then there will be no message.

  * Linux 4.10 commit 401721ecd1dcb0a428aa5d6832ee05ffbdbffbbe finally exports
the x86_64 "phys_base" value in the VMCOREINFO note, so utilize it
whenever it exists.

  * Implemented a new "log -a" option that dumps the audit logs remaining in
kernel audit buffers that have not been copied out to the user-space audit
daemon.

  * Fix for the "kmem " option and the "search" command in x86_64
kernels that contain, or have backports of, kernel commit
7c1da8d0d046174a4188b5729d7579abf3d29427, titled "crypto: sha - SHA1
transform x86_64 AVX2", which introduced an "_end" text symbol.  Without
the patch, if a base kernel symbol address that is larger than the "_end"
text symbol is passed to "kmem ", its symbol/filename information

Bug description:
  Linux kernel packages depend on initramfs-tools | linux-initramfs-
  tool, even when systems using the kernel can be booted without it.

  Demoting the dependency to Recommends: or Suggests: would allow
  creating smaller images without initramfs-tools installed and fully
  skipping initramfs updates upon kernel updates saving time.

  Please consider changing the Depends: to Recommends: or Suggests: for
  kernels capable of booting without initramfs.

  initramfs-tools is still a dependency of ubuntu-minimal thus
  accidental removal of initramfs-tools resulting an unbootable system
  would still be unlikely.

  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

[Kernel-packages] [Bug 1680904] Re: zesty unable to handle kernel NULL pointer dereference

[Matthias]

@chichun I've tried installing you debs, but my uname keeps reflecting
the Jun 30 date. I pull all the debs and install them with `sudo dpkg -i
--force-overwrite *.deb`.

Is there some other magik incantation to force this?

  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

  kern.log entries below. Let me know if you need anything else from me.

  Thanks!

Bug description:
  [Impact]
  ASA (Active Steering Antenna) requires per chain RSSI info. Intel WLAN driver 
has full support for per-chain RSSI information, but ath10k doesn't.

  [Fix]
  The fix is pretty simple just fills up RSSI value to the structure.

  [Test Case]
  RSSI information can be polled from userspace using NL80211 wireless stack.

  [Regression Potential]
  No any regression concern.

  xfs slab objects (memory) leak when xfs shutdown is called

  Confirmed

Bug description:
  [Impact]

   * xfs kernel memory leak in case of xfs shutdown due to i/o errors
   * if xfs on iscsi, iscsi disconnection and module unload will case mem leak

  [Test Case]

   * configure tgtd with 1 lun and make it available through tcp/ip
   * configure open-iscsi to map this lun
   * make sure node.session.timeo.replacement_timeout = 0 in iscsid.conf
   * mount a xfs volume using the lun from tgtd host, run bonnie -d /xfsdir
   * in tgtd server, drop iscsi packets and watch client to have i/o errors
   * after sometime (depending on timeout) xfs will call shutdown
   * make sure the i/o errors led to xfs shutdown (comment #3)
   * after shutdown you try to remove xfs module and it will leak

  [Regression Potential]

   * based on upstream fix
   * tested in the same environment
   * potential damage to xfs

  [Other Info]

I've been experimenting with 4.12.3-041203-generic, not crashes but
sometimes the screen goes blank for 3 seconds, from syslog

Jul 27 14:50:45 XPS13 org.gnome.Shell.desktop[1986]:
intel_do_flush_locked failed: Cannot allocate memory

it recovers nicely, no apps gets killed and nothing gets restarted (
other than gnome desktop ??? )

[Kernel-packages] [Bug 1680904] Re: zesty unable to handle kernel NULL pointer dereference

[Sam Van den Eynde]

@chihchun

Out of interest: could you give the procedure how you build this (I've
seen various recipes online)?

On my system, your debs are considered a lower version to the
repositories that have 4.10.0-28 as well and will offer to "upgrade" it
to the official ones every apt upgrade cycle.

So I guess a version bump would be the easiest way to fix this.

  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

  kern.log entries below. Let me know if you need anything else from me.

  quite often the tests time out on armhf. Maybe this is due to running
  inside a lxc container, rather than in a full VM.

  Could you please consider disabling rebuild test on armhf? Or for
  example lowering its parallelism during adt tests.

  BT fails to load firmware after S3. On my system it's atheros' chip, but the 
same issue can be seen with broadcom's chip, too.
 [542.6274] WARNING: CPU: 0 PID: 20729 at 
/build/linux-MD8jsN/linux-4.4.0/drivers/base/firmware_class.c:1148 
_request_firmware+0x7c2/0xaf0()

  The root cause of this issue is request_firmware() is being called at
  the wrong time.

  [Fix]
  The fix is from this old thread[1], but the patch didn't be accepted by the 
maintainer.
  It prevents the work queue from being re-created and calls request_firmware() 
immediately before usermodehelper is fully resumed. Making the workqueue 
freezable preserves the delay and will postpone the firmware loading time.

  [Test Case]
  Verified on the machine has this issue, and confirm this patch works.

  [Regression Potential]
  From what I can see, I think this change should be safe, and after 240 times 
S3 test, the system and BT functions are still working.

[Kernel-packages] [Bug 1700657] Re: Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB

[F. H.]

I just checked my dmesg:
If ACPI is the problem, shouldn't dmesg show some "elan0651" device (although 
it does not bind any driver to it)?

So, if I cannot find any "elan" string in my dmesg, this should mean that the 
kernel does not find ANY i2c device with a similar hardware name, shouldn't it?
=> ACPI might not be the problem, rather the hardware identification of the 
linux kernel..?

[Kernel-packages] [Bug 1706275] Re: Kernel Panic from intel_dp_set_idle_link_train

[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
v4.13 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.

  When putting my laptop on a docking station the system did not detect
  the external monitor attached via DP. I took the laptop of the station
  and put it back on. Still nothing happend so I decided to reboot the
  system. I opened a browser when the system froze. The mouse was still
  moving but X was dead in all other regards. To see whether something
  was alive I tried to switch to the console via Ctr-Alt-F1. Nothing
  happend for about 5 to 10 seconds and then the kernel panic came up. I
  took a quick photo of the screen which I attached.

  My system is running Ubuntu 17.04. I'm using an upstream kernel:

  Linux 4.11.11-04-generic #201707150838 SMP x86_64 x86_64 x86_64

  My Laptop is a ThinkPad T460s and I'm using the graphics drivers from

[Kernel-packages] [Bug 1699845] Re: System not booting after kernel upgrade to 4.10.0-22, problem persists with 4.10.0-23

[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 v4.10 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.

[Kernel-packages] [Bug 1706141] Re: [ARM64] config EDAC_GHES=y depends on EDAC_MM_EDAC=y

Title:
  [ARM64] config EDAC_GHES=y depends on EDAC_MM_EDAC=y

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Zesty:
  New

Bug description:
  [Impact]
  In configs Zesty and Artful, EDAC_MM_EDAC is set to =m, this disables 
EDAC_GHES. Customers using RAS on ARM64 may want this functionality.

  According to RAS expert at QTI. EDAC_GHES is essential for ARMv8.0
  Server systems, as it enables firmware-first error handling of memory
  and CPU errors. Due to a lack of standard RAS architecture (or machine
  check architecture equivalent) on ARMv8.0 systems, APEI/GHES is the
  only mechanism available for reporting hardware errors (e.g. memory
  and CPU errors). This enables reporting of hardware errors, and also
  helps enable memory fault recovery mechanisms to extend the life of
  the system by offlining pages when recoverable uncorrected errors are
  encountered. Note that other ARM vendors will be going in this
  direction for hardware error handling.

  [Test]
  Test kernel available in 
https://launchpad.net/~centriq-team/+archive/ubuntu/lp1706141

  Boot the kernel and check dmesg for the following:
  $ dmesg | grep -i -E "edac|hest|ghes"
  [0.00] ACPI: HEST 0x0916 000288 (v01 QCOM   QDF2400

  [5.755469] GHES: APEI firmware first mode is enabled by APEI bit and WHEA

  [Fix]
  1. Apply RAS patch series submitted for SRU in Bug #1696570
  2. Set config option EDAC_MM_EDAC=y for ARM64, this will automatically set 
EDAC_GHES=y
  3. Remove edac_core from
  debian.master/abi//arm64/generic.modules

  [Regression Potential]
  The config change is limited to ARM64 architecture, and does not impact any 
other architecture. Potential for regressions is low.

[Kernel-packages] [Bug 1706977] Re: Issues with Nvidia GeForce GT 240M. Can't define monitor and set proper resolution. Also, Redshift doesn't work.

[Alexander Lavrenko]

Yes, after a kernel update. 100%. I've seen that before after installing
4.4.0-75 kernel (or newer version, I don't remember). Ignored kernel
updates for a while, today I've tried to update to 4.4.0-87 and got the
same issues.

Sorry, but I won't install 4.13-rc2 upstream kernel. The process is
complicated + I'm on Linux Mint 18.1 (it's based on 16.04 but obviously
it's not pure 16.04) and I don't wanna risk.

Maybe I could find time to add some log files (if I'll figure out how),
I don't know.

  Lenovo e73 USB webcam problems

Status in linux package in Ubuntu:

Bug description:
  I'm experiencing problems with USB webcam on Lenovo e73 with Ubuntu
  16.04.2 Xenial 32bit.

  Originally with 4.4 connecting the camera often resulted in complete
  hang of the system (apparently not even SysRq worked, though I did not
  test that personally since it is a system I'm administering remotely
  for a family member). There was always a null pointer dereference just
  before the hang, so I suspect that is the culprit (see the attached
  kernel log).

  After some updates the system no longer hangs. I suspect this was
  fixed by going from linux 4.4 to 4.8. However, the webcam still often
  doesn't work and most application just return error. This is usually
  fixed after several tries, but sometimes it is necessary to reboot
  computer. Updating BIOS didn't help. The kernel logs still contain the
  same null pointer dereference with exactly the same stack trace for
  both 4.8 and 4.10.

Bug description:
  == Comment: #0 - BRYANT G. LY  - 2017-05-22 08:40:16 ==
  ---Problem Description---

   - Issue 1: ibmveth doesn't support largesend and checksum offload features
 when configured as "Trunk". Driver has explicit checks to prevent
 enabling these offloads.

   - Issue 2: SYN packet drops seen at destination VM. When the packet
 originates, it has CHECKSUM_PARTIAL flag set and as it gets delivered to
 IO server's inbound Trunk ibmveth, on validating "checksum good" bits
 in ibmveth receive routine, SKB's ip_summed field is set with
 CHECKSUM_UNNECESSARY flag. This packet is then bridged by OVS (or Linux
 Bridge) and delivered to outbound Trunk ibmveth. At this point the
 outbound ibmveth transmit routine will not set "no checksum" and
 "checksum good" bits in transmit buffer descriptor, as it does so only
 when the ip_summed field is CHECKSUM_PARTIAL. When this packet gets
 delivered to destination VM, TCP layer receives the packet with checksum
 value of 0 and with no checksum related flags in ip_summed field. This
 leads to packet drops. So, TCP connections never goes through fine.

   - Issue 3: First packet of a TCP connection will be dropped, if there is
 no OVS flow cached in datapath. OVS while trying to identify the flow,
 computes the checksum. The computed checksum will be invalid at the
 receiving end, as ibmveth transmit routine zeroes out the pseudo
 checksum value in the packet. This leads to packet drop.

   - Issue 4: ibmveth driver doesn't have support for SKB's with frag_list.
 When Physical NIC has GRO enabled and when OVS bridges these packets,
 OVS vport send code will end up calling dev_queue_xmit, which in turn
 calls validate_xmit_skb.
 In validate_xmit_skb routine, the larger packets will get segmented into
 MSS sized segments, if SKB has a frag_list and if the driver to which
 they are delivered to doesn't support NETIF_F_FRAGLIST feature.

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

[David Wilson]

I've ran into this problem several times. After disabling C-states in
the motherboard, my system has been running stable for ~5 weeks uptime
so far.

  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...

  Problem Description
  ===
  cpupower suggests installation of non-existent linux-cloud-tools-generic 
package

  Problem occurs on an IBM POWER 16.04 LTS system. Unknown whether it
  occurs on other architectures or later releases.

  When run _without package "linux-tools-$(uname -r)" installed_,
  cpupower will issue a complaint, suggesting to install (among others),
  some linux-cloud-tools-*-generic packages:

  $ cpupower
  WARNING: cpupower not found for kernel 4.4.0-75

You may need to install the following packages for this specific kernel:
  linux-tools-4.4.0-75-generic
  linux-cloud-tools-4.4.0-75-generic

You may also want to install one of the following packages to keep up to 
date:
  linux-tools-generic
  linux-cloud-tools-generic

  However, those linux-cloud-tools-*-generic package appear not to exist
  --at least not in the default repos.

  Package linux-cloud-tools-common exists, but none of the *-generic
  packages are available:

  $ apt-cache policy "linux-cloud-*"
  $ cat xxx
  linux-cloud-tools-common:
Installed: (none)
Candidate: 4.4.0-78.99
Version table:
   4.4.0-78.99 500

  500 http://us.ports.ubuntu.com/ubuntu-ports xenial/main ppc64el 
Packages

  
  The cpupower command works (at least doesn't give this complaint) if the 
appropriate linux-tools-$(uname -r) (perhaps via linux-tools-generic) is 
installed, so the cloud package is maybe not needed (as least for some 
functionality).

  I think the fix is to either: 
  a) supply the cloud packages for POWER, or 
  b) remove the non-existent packages from cpupower's complaint message.
   
  ---uname output---
  Linux fs3 4.4.0-75-generic #96-Ubuntu SMP Thu Apr 20 09:55:30 UTC 2017 
ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = Firestone 
   
  ---Steps to Reproduce---
   Install linux-tools-common but NOT linux-tools-*-generic on a POWER 16.04 
LTS system, then run cpupower.

  Userspace rpm: linux-tools-common

Bug description:
  Note: Updates are being staged at ppa:dannf/arm64-kdump.

  [Impact]
  It is not possible to collect a kernel crash dump from a crashed arm64 server 
for later debugging.

  [Test Case]
  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,

Bug description:
  Note: Updates are being staged at ppa:dannf/arm64-kdump.

  [Impact]
  It is not possible to collect a kernel crash dump from a crashed arm64 server 
for later debugging.

  [Test Case]
  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.

  we have two devices which use the chip,when we test the throughput between 
the two devices, we found some probles:
  1.the throughput of upload is much lower than the download,at the idel 
environment,the upload throughput is about 200Mbps but the download throughput 
is 350Mbps.
  2.when we restart the device and test the throughput between the two 
devices,the upload throughput is very low at the first time,then it gos up to 
the normal value slowly,sometimes it can't, the value is between 1mbps  to 
10mbps.

  so i want to know how can i fix the two probles,can you help me.

   * kdump doesn't work on non-efi systems
   * a kernel dump can't be generated

  [Test Case]

   * install kdump-tools
   * configure kdump-tools (/etc/default/kdump-tools)
   * try to start kdump-tools service (kdump-config start)
   * while executing kexec, you will get:
 "efi memory descriptor version 0 is not supported!"

  [Regression Potential]

   * in theory it could brake kdump for efi systems
   * in practice, its based on upstream regression fix (not included in Trusty)
   * it has also been tested in 3 different setups and it worked

  [Other Info]

  Based on upstream code commit explanation:

  """
  On non-EFI systems, efi_info section of boot_params is zero filled resulting
  in an erroneous message from kexec regarding "efi memory descriptor" version.

  Caused by commit: e1ffc9e9a0769e1f54185003102e9bec428b84e8 "Passing efi

  It was brought to my attention to some of our users are facing this:

  Hello Everybody,

  since last update from ubuntu 16.04.2, last night, my servers are
  randomly not able to read and write from shared folders. I got this
  message:

  lsof: WARNING: can't stat() cifs file system /mnt/record
    Output information may be incomplete.
  lsof: WARNING: can't stat() cifs file system /mnt/record
    Output information may be incomplete.

  rsync error: errors selecting input/output files, dirs (code 3) at 
main.c(652) [Receiver=3.1.1]

  This comes from my cron script.

  When I type df -h it takes sometimes very long to get the list. And it
  also can be that the mounted share is disconnected and I have to mount
  -a (what also takes long) again.

  My fstab have this command:

  //address /mnt/storage cifs

  Linux kernel packages depend on initramfs-tools | linux-initramfs-
  tool, even when systems using the kernel can be booted without it.

  Demoting the dependency to Recommends: or Suggests: would allow
  creating smaller images without initramfs-tools installed and fully
  skipping initramfs updates upon kernel updates saving time.

  Please consider changing the Depends: to Recommends: or Suggests: for
  kernels capable of booting without initramfs.

  initramfs-tools is still a dependency of ubuntu-minimal thus
  accidental removal of initramfs-tools resulting an unbootable system
  would still be unlikely.

  Azure hosts are not supporting non-TCP port numbers in vRSS hashing for
  now. For example, UDP packet loss rate will be high if port numbers are
  also included in vRSS hash.

  So, we created this patch to use only IP numbers for hashing in non-TCP
  traffic.

[Kernel-packages] [Bug 1680904] Re: zesty unable to handle kernel NULL pointer dereference

[Michael Stucki]

@chihchun Actually I could not install your kernel on 16.04 without
breaking dependencies. It requires binutils >= 2.29 (or 2.28, not sure
if I remember correctly) but Ubuntu 16.04 only includes version 2.26. So
I manually edited the config file in your archive to remove that
restriction. I guess other users will be affected by this, too...

Nevertheless, your kernel (4.10.0-28-generic #32 SMP Sat Jul 22 12:39:20
UTC 2017 x86_64 x86_64 x86_64 GNU/Linux) seems to fix the problem. At
least I never had any additional crashes since then...

  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

Title:
  [ARM64] config EDAC_GHES=y depends on EDAC_MM_EDAC=y

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Zesty:
  New

Bug description:
  [Impact]
  In configs Zesty and Artful, EDAC_MM_EDAC is set to =m, this disables 
EDAC_GHES. Customers using RAS on ARM64 may want this functionality.

  According to RAS expert at QTI. EDAC_GHES is essential for ARMv8.0
  Server systems, as it enables firmware-first error handling of memory
  and CPU errors. Due to a lack of standard RAS architecture (or machine
  check architecture equivalent) on ARMv8.0 systems, APEI/GHES is the
  only mechanism available for reporting hardware errors (e.g. memory
  and CPU errors). This enables reporting of hardware errors, and also
  helps enable memory fault recovery mechanisms to extend the life of
  the system by offlining pages when recoverable uncorrected errors are
  encountered. Note that other ARM vendors will be going in this
  direction for hardware error handling.

  [Test]
  Test kernel available in 
https://launchpad.net/~centriq-team/+archive/ubuntu/lp1706141

  Boot the kernel and check dmesg for the following:
  $ dmesg | grep -i -E "edac|hest|ghes"
  [0.00] ACPI: HEST 0x0916 000288 (v01 QCOM   QDF2400

  [5.673371] ghes_edac: Unfortunately, not all BIOSes reflect the memory 
layout correctly.
  [5.681542] ghes_edac: So, the end result of using this driver varies from 
vendor to vendor.
  [5.689972] ghes_edac: If you find incorrect reports, please contact your 
hardware vendor
  [5.698142] ghes_edac: to correct its BIOS.

ghes_edac: DEV ghes (INTERRUPT)
  [5.755469] GHES: APEI firmware first mode is enabled by APEI bit and WHEA 
_OSC.

  [Fix]
  1. Apply RAS patch series submitted for SRU in Bug #1696570
  2. Set config option EDAC_MM_EDAC=y for ARM64, this will automatically set 
EDAC_GHES=y
  3. Remove edac_core from
  debian.master/abi//arm64/generic.modules

  [Regression Potential]
  The config change is limited to ARM64 architecture, and does not impact any 
other architecture. Potential for regressions is low.

Title:
  Hardware clock isn't updated anymore

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  For some months I'm noticing that my hardware clock doesn't get updated 
anymore while the software clock successfully updates ("ntpd -q" runs every 
hour). This appears on my laptop (kernel version 4.11.10) and my PC (kernel 
version 4.8.17). Could it be that the 11 minute mode was enabled in past kernel 
versions but not anymore in recent kernel versions?

Title:
  Hardware clock isn't updated anymore

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  For some months I'm noticing that my hardware clock doesn't get updated 
anymore while the software clock successfully updates ("ntpd -q" runs every 
hour). This appears on my laptop (kernel version 4.11.10) and my PC (kernel 
version 4.8.17). Could it be that the 11 minute mode was enabled in past kernel 
versions but not anymore in recent kernel versions?
