[Bug 1888543] Re: hwclock: fails to set time on glibc 2.31

[Łukasz Zemczak]

Hello Jakob, or anyone else affected,

Accepted busybox into groovy-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/busybox/1:1.30.1-4ubuntu9.1 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-
groovy to verification-done-groovy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-groovy. 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.

Title:
  hwclock: fails to set time on glibc 2.31

Status in busybox package in Ubuntu:
  Confirmed
Status in busybox source package in Focal:
  Fix Committed
Status in busybox source package in Groovy:
  Fix Committed
Status in busybox package in Debian:
  Confirmed

Bug description:
  [Impact]
   * With glibc 2.31, hwclock from busybox is unable to set the system time
     due to the changes in settimeofday behavior.

  [Test Case]
  * Run:
    sudo busybox hwclock -s

  * It should succeed in the fixed version

  [Where problems could occur]
  * The fix calls the originally called glibc function twice, instead of passing both non-NULL parameters at once. If this compiles there should be no other issue.

  [Original Bug Text]
  With glibc 2.31, hwclock from busybox is unable to set the system time
  due to the changes in settimeofday behavior.

  The problem has been reported upstream in [1] which also contains a
  patch.

  hwclock from busybox is important as it's used on the Raspberry Pi to set the system
  time when an RTC is present.

  This bug applies to focal and groovy.
