Re: Fetchmail as root

Thanks.

Should I still open a bugzilla entry or not? After all I am not using rawhide, but f21 :)

I just added

allow fetchmail_t self:key manage_key_perms;

to git in Rawhide.  This should fix the problem.

It is always good to open a bugzilla on issues like this.

Hi,

I am using fetchmail as root to collect emails.

fetchmail is launched by systemd through a fetchmail.service (see below)

The /etc/fetchmail.conf file contains a list as
poll mail.server.com with
    interval 1
    protocol imap port 993
    username "user" password "pass" is name@xxxxxxxxxx
    ssl
    keep
;

As a result I have the following selinux messages (sealert below):

What can I do to have a more useful information to solve this problem? Actually this is the last AVC appearing in my logs and I want to solve it before changing the permissive mode to enforcing.

SELinux is preventing fetchmail from read access on the key Unknown.

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

If you believe that fetchmail should be allowed read access on the Unknown key 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:
# grep fetchmail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
