Description Daniel Stripes 2010-08-22 01:17:34 UTC 
Summary:

SELinux is preventing minirosetta_2.1 "signal" access .

Detailed Description:

[minirosetta_2.1 has a permissive type (boinc_t). This access was not denied.]

SELinux denied access requested by minirosetta_2.1. It is not expected that this
access is required by minirosetta_2.1 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
report.

Daniel,
if you execute

restorecon -R -v /var/lib/boinc

does it fix any contexts?

Yes, many.  I will see whether they hold and whether "signal" access issue persists.

Thank you.
