Description of problem: When I try to use GSS Proxy from Apache httpd, I get AVC denials type=AVC msg=audit(1378278187.873:99): avc: denied { write } for pid=1679 comm="httpd" name="default.sock" dev="dm-1" ino=2100982 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:gssproxy_var_lib_t:s0 tclass=sock_file type=AVC msg=audit(1378278187.873:99): avc: denied { connectto } for pid=1679 comm="httpd" path="/var/lib/gssproxy/default.sock" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:gssproxy_t:s0 tclass=unix_stream_socket and I've also seen type=AVC msg=audit(1378278175.323:97): avc: denied { search } for pid=1677 comm="httpd" name="gssproxy" dev="dm-1" ino=2100970 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:gssproxy_var_lib_t:s0 tclass=dir I can see two possibilities -- adding the necessary allows, something like allow httpd_t gssproxy_t:unix_stream_socket connectto; allow httpd_t gssproxy_var_lib_t:dir search; allow httpd_t gssproxy_var_lib_t:sock_file write; or gssproxy_read_lib_files(httpd_t) userdom_unpriv_type(httpd_t) or having these behind some SELinux boolean. Version-Release number of selected component (if applicable): mod_auth_kerb-5.4-24.fc19.x86_64 httpd-2.4.6-2.fc19.x86_64 gssproxy-0.2.3-6.fc19.x86_64 selinux-policy-targeted-3.12.1-73.fc19.noarch How reproducible: Deterministic. Steps to Reproduce: 1. Set up Apache with GSS Proxy using for example the steps at https://fedorahosted.org/gss-proxy/wiki/Apache 2. kinit to get a valid ticket 3. Do a GET https request. Actual results: With enforcing, ISE 500 and some AVC denials. In permissive, things works but more AVC denials. Expected results: Things working in enforcing without AVC denials, potentially with some boolean enabled to allow httpd_t to communicate with the GSS Proxy. Additional info:
