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

[Balint Reczey]

** Changed in: busybox (Ubuntu Focal)
       Status: New => Confirmed

** Description changed:

+ [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.
