You can add port using semanage port -a -t mail_port_t -p tcp 3905 But is mupdate something I should have defined as a mail_port? Or should I define its own port? Any other programs need to use it? In cyrus policy it looks like the mail_port is defined as 2000, so I will add this port to the policy. Fixed in selinux-policy-2.4.6-248.el5 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.

Description of problem: I am trying to reproduce a cyrus-imapd bug involving mupdate usage. However, I cannot get mupdate working with selinux enabled, because it denies cyrus-master to bind the mupdate port (both in master and client mupdate configuration). Version-Release number of selected component (if applicable): selinux-policy-2.4.6-243.el5 How reproducible: always Steps to Reproduce: 1. create mupdate enabled cyrus-imapd configuration (i.e. add "mupdate cmd="mupdate -m" listen=3905 prefork=1" to "SERVICES" section in /etc/cyrus.conf to run in master mode, or create appropriate configuration in /etc/imapd.conf) 2. service cyrus-imapd start 3. grep cyrus /var/log/audit/audit.log | grep denied 4. grep denied /var/log/maillog Actual results: type=AVC msg=audit(1244558374.392:80): avc: denied { name_bind } for pid=4515 comm="cyrus-master" src=3905 scontext=root:system_r:cyrus_t:s0 tcontext=system_u:object_r:port_t:s0 tclass=tcp_socket Jun 9 10:39:34 dell-pesc430-01 master[4515]: unable to create mupdate listener socket: Permission denied Expected results: (no errors reported, server listening on the appropriate port) Additional info: note that although 3905 is standard value, the port number may be reconfigured
