Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Ahmed Eladawy 2019-05-14 12:02:47 UTC 
Description of problem:

- If the kernel-debug is installed on the machine, the tracer command output will be like the following even after rebooting the machine.

You should restart:
  * These applications rebooting your computer:
      kernel
- This will case the machine to be marked as "Reboot Required" on the machine Properties and on Content Hosts

Application    | Type	   |  Helper
kernel	       | static	   |  You will have to reboot your computer

Version-Release number of selected component (if applicable):

katello-host-tools-tracer-3.3.5-3.el7sat.noarch
tracer-common-0.7.0-3.el7sat.noarch
python2-tracer-0.7.0-3.el7sat.noarch


How reproducible:Confirmed

Steps to Reproduce:
1. Install katello-host-tools-tracer package on any registered machine.
2. Install kernel-debug package
3. Reboot the machine.
4. Run "tracer -a"
5. Check the machine on the satellite "All Hosts" and "Content Hosts -> Traces"

Actual results:

You should restart:
  * These applications rebooting your computer:
      kernel

Expected results:

The machine does not need to be rebooted because of the kernel.
Comment 3 Ahmed Eladawy 2019-05-14 12:06:39 UTC 
Extract the kernel checking code from /usr/lib/python2.7/site-packages/tracer/resources/tracer.py and run it on the machine :

------
        def _has_updated_kernel(self):
                if os.path.isdir('/lib/modules/'):
                        for k_version in next(os.walk('/lib/modules/'))[1]:
                                if parse_version(os.uname()[2]) < parse_version(k_version):
                                        return True
                        return False
                return False
-----

Run it on the machine after modifying it to print the valuses:

-----
import os
from pkg_resources import parse_version

print "All Installed Kernel"
print next(os.walk('/lib/modules/'))[1]
print "Current running kernel"
print os.uname()[2]

for k_version in next(os.walk('/lib/modules/'))[1]:
	if parse_version(os.uname()[2]) < parse_version(k_version):
		print parse_version(os.uname()[2]) 
		print parse_version(k_version) 
-----

The output:

All Installed Kernel
