Hi,
I'm installing bugzilla from epel-5 onto a Centos-5 Server. I'm getting the
following AVC denied message:
Summary
SELinux prevented httpd reading and writing access to http files.
Detailed Description
SELinux prevented httpd reading and writing access to http files.
Ordinarily
httpd is allowed full access to all files labeled with http file context.
This machine has a tightened security policy with the httpd_unified turned
off, This requires explicit labeling of all files. If a file is a cgi
script it needs to be labeled with httpd_TYPE_script_exec_t in order to be
executed. If it is read only content, it needs to be labeled
httpd_TYPE_content_t, it is writable content. it needs to be labeled
httpd_TYPE_script_rw_t or httpd_TYPE_script_ra_t. You can use the chcon
command to change these context. Please refer to the man page "man
httpd_selinux" or http://fedora.redhat.com/docs/selinux-apache-fc3 "TYPE"
refers toi one of "sys", "user" or "staff" or potentially other script
types.
Allowing Access
Changing the "httpd_unified" boolean to true will allow this access:
"setsebool -P httpd_unified=1"
The following command will allow this access:
setsebool -P httpd_unified=1

This seems to a denial to r/w a file in /tmp
I can generate a local policy to allow this access with audit2allow but what
is the correct way to handle this.
The answer was within the report itself
# setsebool -P httpd_unified=1
