Description Horst H. von Brand 2011-07-15 17:07:15 UTC
SELinux is preventing /usr/sbin/prelink from 'read' accesses on the file /etc/pki/tls/certs/Makefile.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that prelink should be allowed read access on the Makefile file 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 prelink /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-07-19 11:39:32 UTC
I would imagine 

/etc/pki/tls/certs/Makefile

is marked as executables. 

# chcon -t bin_t /etc/pki/tls/certs/Makefile


But what does

# stat /usr/share/man/man1/ca.1ssl.gz
