Bug 947439

Here are the actual AVCs from my audit log, one for each attempt of getcert:

certmonger failed to start tracking certificate: Command '/usr/bin/getcert start-tracking -d /var/lib/pki-ca/alias -n auditSigningCert cert-pki-ca -c dogtag-ipa-renew-agent -B /usr/lib64/ipa/certmonger/stop_pkicad -C /usr/lib64/ipa/certmonger/renew_ca_cert "auditSigningCert cert-pki-ca" -P XXXXXXXX' returned non-zero exit status 1

And the following custom policy 'fixes' the issue.

module fixcertmongerpkica 1.0;

require {
        type certmonger_t;
        type pki_tomcat_var_lib_t;
        class dir search;
}

#============= certmonger_t ==============
allow certmonger_t pki_tomcat_var_lib_t:dir search;

Martin,
could you re-test it in permissive mode to see if we get more AVCs. Thank you.

This is what I see when I upgrade Fedora 17 with IPA installed to Fedora 18:

# getenforce 
Permissive
# grep AVC /var/log/audit/audit.log 
# yum distro-sync --releasever=18
...
Complete!

# grep AVC /var/log/audit/audit.log

From that list, only this one looks relevant to IPA:

type=AVC msg=audit(1364990520.748:161): avc:  denied  { unlink } for  pid=1093 comm="java" name="1085" dev="dm-0" ino=15753 scontext=system_u:system_r:pki_tomcat_t:s0 tcontext=system_u:object_r:tmp_t:s0 tclass=file

When I then update to freeipa-server-3.1.3, I see the reported AVC:

# yum update freeipa-server --enablerepo=updates-testing
...
# grep AVC /var/log/audit/audit.log 
...
type=AVC msg=audit(1364994343.817:33): avc:  denied  { search } for  pid=779 comm="certmonger" name="pki-ca" dev="dm-0" ino=17861 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:object_r:pki_tomcat_var_lib_t:s0 tclass=dir

That makes sense to me.  When I do a distro-sync, it's always in permissive mode, as there is no real way to recover from SELinux issues during the upgrade.  Then after a 'touch /.autorelabel' and cleaning up other *.conf files, etc, I reboot.

It wasn't until the further upgrade of freeipa-server that I got the certmonger SELinux denials issues.

Your example basically replicated my situation with certmonger.

Hello, was there any update to this Bugzilla? Do you need more information?

Thanks,
Martin
