  [impact]

  40-vm-hotadd.rules unconditionally tries onlining memory, which
  results in logged error messages if the memory is already online

  [test case]

  since this rules file restricts operation to only hyper-v or xen
  guests, boot a hyper-v or xen vm guest, and check for logged error
  msgs like:

  Apr 29 22:36:46 focal01 systemd-udevd[266]: memory7:
  /usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
  ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
  argument

  alternately, to test on a vm guest other than hyper-v or xen,
  comment/remove the 'GOTO="vm_hotadd_end"' line from the rules file and
  reboot.

  [regression potential]

  as this adds a check before attempting to online memory for hyper-v
  and xen vm guests, any regression would likely involve failure to
  correctly online all memory on those guest platforms.

  [scope]

  this rule has been around for a long time, so is needed for x/b/f/g.

  [original description]

  In focal, udev's 40-vm-hotadd.rules (from debian/extra/rules-ubuntu)
  tries to write to invalid (as of 5.4.0-1010-azure) sysfs nodes
  resulting in warnings such as:

  argument

  Perhaps 40-vm-hotadd.rules needs to be updated for 5.4 semantics,
  removed, or something else. This behavior is present on systems
  upgraded from 18.04 (via d-r-u) as well as new focal systems, upon

2020-07-30 Thread Ɓukasz Zemczak
Hello Jose, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.42 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

2020-07-15 Thread Robie Basak
Hello Jose, or anyone else affected,

Accepted systemd into focal-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/245.4-4ubuntu3.2 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,

Bug description:
  [impact]

  40-vm-hotadd.rules unconditionally tries onlining memory, which
  results in logged error messages if the memory is already online

  [test case]

  since this rules file restricts operation to only hyper-v or xen
  guests, boot a hyper-v or xen vm guest, and check for logged error
  msgs like:

  Apr 29 22:36:46 focal01 systemd-udevd[266]: memory7:
  /usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
  ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
  argument

  alternately, to test on a vm guest other than hyper-v or xen,
  comment/remove the 'GOTO="vm_hotadd_end"' line from the rules file and
  reboot.

  [regression potential]

  as this adds a check before attempting to online memory for hyper-v
  and xen vm guests, any regression would likely involve failure to
  correctly online all memory on those guest platforms.

  [scope]

  this rule has been around for a long time, so is needed for x/b/f/g.

  [original description]

  In focal, udev's 40-vm-hotadd.rules (from debian/extra/rules-ubuntu)
  tries to write to invalid (as of 5.4.0-1010-azure) sysfs nodes
  resulting in warnings such as:

  /usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
  ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
  argument

  Perhaps 40-vm-hotadd.rules needs to be updated for 5.4 semantics,
  removed, or something else. This behavior is present on systems
  upgraded from 18.04 (via d-r-u) as well as new focal systems, upon
  first reboot of the VM.

The upstream default, DNSSEC=allow-downgrade can lead to compatibility

safer and more consistent to just generally change the default to
DNSSEC=no. (Closes: #959996)

2020-05-02 Thread Dan Streetman
> Apr 29 22:36:46 focal01 systemd-udevd[266]: memory7:
/usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
argument

This isn't because the file doesn't exist, because the udev rule checks
for its existence before trying to write to it.  The error is because
the kernel is rejecting the write to its state file for some reason.  In
a really quick test, it seems like this is because it's already online;
the kernel default has been CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE=y since
at least 4.15.

I think the error message is harmless, since the memory is already
online, but the udev rule should be fixed to check if it's offline
before actually trying to online it.

Can you test with the systemd from this ppa to see if the error message is gone?
https://launchpad.net/~ddstreet/+archive/ubuntu/lp1876018

Also please make sure all your memory and cpus are online after
booting/hotadding.

Note that I might just remove this rule entirely, since it really
shouldn't be needed anymore, now that the kernel default is to online
hotplugged cpus/memory, but I want to verify that first.
