Description Kevin Cousin 2017-06-06 09:39:33 UTC
Description of problem:
I install collectd on my laptop an add LVM plugin. So collectd should be authorized to access to lvm.conf file.
SELinux is preventing reader#2 from 'getattr' accesses on the file /etc/lvm/lvm.conf.

*****  Plugin catchall (100. confidence) suggests   **************************

If vous pensez que reader#2 devrait être autorisé à accéder getattr sur lvm.conf file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
allow this access for now by executing:
# ausearch -c 'reader#2' --raw | audit2allow -M my-reader2
# semodule -X 300 -i my-reader2.pp

Noting issue seems to persist with selinux-policy-3.13.1-225.18.fc25:

[root@localhost ~]# cat /etc/redhat-release
Fedora release 25 (Twenty Five)

[root@localhost ~]# rpm -qa | grep 'selinux-policy-targeted\|collectd-5'

                                        If you believe that reader#3 should be allowed getattr access on the b8:51 file by default.
                                        Then you should report this as a bug.
                                        You can generate a local policy module to allow this access.
                                        Do
                                        allow this access for now by executing:
                                        # ausearch -c 'reader#3' --raw | audit2allow -M my-reader3
                                        # semodule -X 300 -i my-reader3.pp

Comment 5 Evan Tepsic 2017-07-01 14:30:45 UTC
(In reply to Evan Tepsic from comment #4)

Apparently different though as this seems to be /run/udev/data/b8:51
