Summary: SELinux is preventing /usr/sbin/iceccd "execute" access on gcc. Detailed Description: [iceccd has a permissive type (iceccd_t). This access was not denied.] SELinux denied access requested by iceccd. It is not expected that this access is required by iceccd 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.

After this, the iceccd deamon is dead. A "service icecream restart" will help for a while.
Seems like a strange priv? iceccd is executing gcc that it downloaded to /tmp?
Could you attach your /etc/sysconfig/icecream ? I'm curious if you changed ICECREAM_BASEDIR. By default the config file specifies /var/cache/icecream which is labeled with the type iceccd_cache_t. If you are using a different directory, it would have to be labeled with the same context (for example using "semange fcontext -a -e /var/cache/icecream /your/alternative/dir")
You are right. My ICECREAM_BASEDIR points to /tmp/icecream After # semanage fcontext -a -e /var/cache/icecream /tmp/icecream # restorecon /tmp/icecream # ls -Zd /tmp/icecream drwxr-xr-x. root root system_u:object_r:iceccd_cache_t:s0 /tmp/icecream iceccd is working now. Many Thanks
