From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.7.8) Gecko/20050512 Red Hat/1.0.4-1.4.1 Firefox/1.0.4 Description of problem: I have squid configured as an http accellerator listening on port 80. When selinux is enabled it does not start. The error message in cache.log is: 2005/06/09 20:22:41| commBind: Cannot bind socket FD 13 to x.x.x.x:80: (13) Permission denied 2005/06/09 20:22:41| commBind: Cannot bind socket FD 13 to x.x.x.y:80: (13) Permission denied When selinux is in permissive mode it starts correctly. The only logging in syslog is: Jun 9 11:34:06 hydra1 kernel: audit(1118313246.485:0): avc: denied { getattr } for pid=3187 comm=squid path=/boot dev=sda1 ino=2 scontext=root:system_r:squid_t tcontext=system_u:object_r:boot_t tclass=dir This is displayed once per child process. It does not appear to be the cause of the failure. Russell Coker said: I guess that you changed the port number as well as the IP address. squid_t is permitted to bind to ports of type http_cache_port_t, that means the following ports (from the net_contexts file): portcon tcp 3128 system_u:object_r:http_cache_port_t portcon tcp 8080 system_u:object_r:http_cache_port_t portcon udp 3130 system_u:object_r:http_cache_port_t portcon tcp 8118 system_u:object_r:http_cache_port_t We can solve that with the following policy. bool squid_use_http_port false; if (squid_use_http_port) { allow squid_t http_port_t:tcp_socket name_bind; } Version-Release number of selected component (if applicable): selinux-policy-targeted-1.17.30-2.88 squid-2.5.STABLE6-3.4E.5 How reproducible: Always Steps to Reproduce: 1. Install Squid 2. Enable the targetted policy 3. Change http_port to 80 in /etc/squid/squid.conf 4. service squid start Actual Results: Squid fails to bind to its network ports Expected Results: Squid starts Additional info:
