Description Paul Thompson 2007-08-13 13:27:28 UTC
Description of problem:
SELinux alert prevents mailman from succesfull hostname change operation

Version-Release number of selected component (if applicable):
mailman.i386                             3:2.1.9-5              installed       
selinux-policy.noarch                    2.6.4-30.fc7           installed  

How reproducible:
Change website hostname setting in /etc/mailman/mm_cfg.py. Upon restart mailman
throws error.
I suspect mailman is trying to update the hostname in its generated pages, as
the change I made has had no effect.
Otherwise, mailman seems to work, no error evident in log files.

Steps to Reproduce:
1. See above
Actual results:
    SELinux is preventing python (mailman_cgi_t) "search" to httpd

Detailed Description
    SELinux denied access requested by python. It is not expected that this
    access is required by python 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
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for httpd, restorecon -v httpd If
    this does not work, there is currently no automatic way to allow this
    access. Instead,  you can generate a local policy module to allow this
    access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you
    can disable SELinux protection altogether. Disabling SELinux protection is
    not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
