[Bug 2031683] Re: systemd FTBFS on ppc64el due to fuzzer failures

[Łukasz Zemczak]

Hello Nick, or anyone else affected,

Accepted systemd into lunar-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/252.5-2ubuntu3.1 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-
lunar to verification-done-lunar. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-lunar. 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.

** Changed in: systemd (Ubuntu Lunar)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-lunar

Title:
  systemd FTBFS on ppc64el due to fuzzer failures

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Lunar:
  Fix Committed

Bug description:
  [Impact]

  systemd FTBFS on ppc64el due to failing fuzz tests.

  [Test Plan]

  The build-time tests and fuzzing should pass so that the build
  ultimately passes on ppc64el.

  [Where problems could occur]

  The patch just removes the "pure" attribute from
  bus_message_type_from_string, because that attribute was incorrect for
  the behavior of the function. Hence, the regression potential should
  be limited to building the package.

  [Original Description]

  This PPA build[1] demonstrates the issue, the relevant part being:

  [ ... ]
  1061/1066 systemd:dist-check / check-help-networkctl                           OK                0.04s

  1066/1066 systemd:dist-check / parse-hwdb                                      OK                5.43s

  Summary of Failures:

  make: *** [debian/rules:312: binary-arch] Error 2
  dpkg-buildpackage: error: debian/rules binary-arch subprocess returned exit status 2

  This appears to be related to a toolchain change, because I get the
  same result when doing a no-change rebuild of systemd on ppc64el in
  Lunar (i.e. the FTBFS is not introduced by the changes I am testing).
