Description Rob Crittenden 2010-09-10 20:42:14 UTC
Description of problem:

An AVC is raised when certmonger tries to start tracking a 389-ds certificate.

Trying this:

/usr/bin/ipa-getcert start-tracking -d /etc/dirsrv/slapd-EXAMPLE-COM/ -n Server-Cert -p /etc/dirsrv/slapd-EXAMPLE-COM//pwdfile.txt

results in an AVC:

type=AVC msg=audit(1284133660.691:57): avc: denied { search } for pid=2418 comm="certmonger" name="httpd" dev=dm-0 ino=133424 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:object_r:httpd_config_t:s0 tclass=dir

Version-Release number of selected component (if applicable):


Steps to Reproduce:
1. Install 389-ds
2. Install an SSL certificate for it
3. Put the SSL password into pwdfile.txt in the instance directory
3. /sbin/service certmonger start
4. /usr/bin/ipa-getcert start-tracking -d /etc/dirsrv/slapd-EXAMPLE-COM/ -n Server-Cert -p /etc/dirsrv/slapd-EXAMPLE-COM//pwdfile.txt

Comment 3 Dmitri Pal 2010-10-06 14:28:43 UTC
During installation of IPA I also observed the following:

root        : ERROR    certmonger failed starting to track certificate: Command '/usr/bin/ipa-getcert start-tracking -d /etc/dirsrv/slapd-HOME/ -n Server-Cert -p /etc/dirsrv/slapd-HOME//pwdfile.txt' returned non-zero exit status 1


SELinux is preventing /usr/sbin/certmonger "search" access on dirsrv.

Detailed Description:

SELinux denied access requested by certmonger. It is not expected that this
access is required by certmonger and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug

Comment 4 Nathan Kinder 2010-11-30 16:59:29 UTC
The dirsrv policy was recently moved into the base selinux-policy package, so certmonger can now use the dirsrv interface macros.  I'll move this bug to the proper product/component.

For Dmitri's issue, the following needs to be added to the certmonger policy:


I'm not so sure about the AVC that Rob initially reported.  It is related to a "httpd" directory that is labelled as httpd_config_t.  I believe that this AVC is some other issue, as that doesn't appear to be a dirsrv directory.  Can this AVC still be reproduced?  It seems that Dmitri did not see the same AVC when running an install of IPA.

Comment 5 Dmitri Pal 2010-11-30 18:22:43 UTC
I will retest as soon as this policy is pushed to Fedora 13.

Comment 6 Miroslav Grepl 2010-12-09 13:17:15 UTC
This is was fixed in Rawhide, F14, F13 and RHEL6 policy.

Comment 7 Miroslav Grepl 2010-12-09 13:18:12 UTC
This was fixed in Rawhide, F14, F13 and RHEL6 policy.
