Description David L. Crow 2021-05-13 20:44:37 UTC

Description of problem:

needs-restarting -r is calculating the wrong boot time, so it is not correctly detecting a need to restart.  I think this is a regression caused by the changes introduced in bug 1914251.


Version-Release number of selected component (if applicable): python3-dnf-plugins-core-4.0.19-1.fc34.noarch


How reproducible: every time


Steps to Reproduce:

These are steps that I ran just now after a new kernel was installed at 6:30a this morning.

# needs-restarting -r
No core libraries or services have been updated since boot-up.
Reboot should not be necessary.
# uptime
 15:35:25 up 8 days,  6:51,  2 users,  load average: 0.07, 0.07, 0.08
# ls -la /proc/1/cmdline
-r--r--r-- 1 root root 0 May 13 06:59 /proc/1/cmdline
# cat /proc/stat | grep btime
btime 1620222248
# uname -r
5.11.17-300.fc34.x86_64
# rpm -q kernel
kernel-5.11.17-300.fc34.x86_64
kernel-5.11.19-300.fc34.x86_64

Actual results:

Does not indicate that a restart is necessary.

Expected results:

Should indicate that a restart is necessary.

If I reverse apply the patch in bug 1914251 so that the boot time is calculated correctly, I receive the following output:

Core libraries or services have been updated since boot-up:
  * glibc
  * kernel
  * systemd
