:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that cupsd should be allowed write access on the subscriptions.conf.O <Unknown> 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 cupsd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-02-20 16:23:24 UTC
When is this file created?

/etc/cups/subscriptions.conf.O

Comment 2 Daniel Walsh 2012-02-20 19:36:21 UTC
I added file_name_transition rules for this, although I had a typo.

I would figure this is being created in an initrc or by a program a user is running.

Comment 3 Tim Waugh 2012-02-21 10:33:32 UTC
cupsd creates *.O when modifying files in /etc/cups.

Comment 4 Daniel Walsh 2012-02-21 13:54:49 UTC
Is it created by the init script.  SELinux should blocked it from creating the file as cupds_etc_t.  Or does an an admin command running cups create the file?

Comment 5 Tim Waugh 2012-02-22 16:14:50 UTC
This file (subscriptions.conf) can be modified by cups as part of normal operation, e.g. user logging in at the console.  It just means that a client has connected and is asking for updates about a particular set of events (e.g. job changes, printer changes, etc).

Comment 6 Daniel Walsh 2012-02-22 20:46:44 UTC
Anyways it should be fixed in selinux-policy-3.10.0-91.fc17.noarch
