After upgrading neutron from Wallaby to Xena(not ovn), the customer's neutron-l3-agent can't be restarted because of below error [1]
This is because vrrp_pcount = linux_utils.get_process_count_by_name("keepalived")
https://github.com/openstack/neutron/blob/16.4.1/neutron/agent/linux/utils.py#L205
We may put entry to apparmor profile for /proc
but I also find below commit
https://opendev.org/openstack/neutron/commit/f430cd00725f8303f5313cb7784c9aed4b982e62
which is not included in Xena, it is removing code using get_process_count_by_name()
Also, if we backport it. it could be fixed as well.
Could you please give any advice for this issue?
Thanks a lot.

This commit introduced apparmor issue.
https://opendev.org/openstack/neutron/commit/aa2f05870106d0402f4bd4c3f425c62ed11a2e7a
But from Yoga, below commit is included and the issue is gone.
https://opendev.org/openstack/neutron/commit/f430cd00725f8303f5313cb7784c9aed4b982e62
So the same issue will be happening in Wallaby and Xena.
However, still we have potential issue with aa2f05870106d0402f4bd4c3f425c62ed11a2e7a
If some function calls this, there must be the same issue.
apparmor may include proper profile for this.
