Implement cobblerd policy. My previous version had a minor bug in admin_role where it was using cobblerd_var_log_t, and cobblerd_var_lib_t instead of cobbler_var_log_t, and cobbler_var_lib_t. Whilst i was at it, i decided the implement a cobbler_etc_t for cobbler content in /etc. This because you cannot admin a cobbler environment witouth having access to cobbler config files and i dont want to give cobbler_admin access to manage etc_t. As a consequence if this i also removed the files_read_etc_files(cobblerd_t), as i think that cobbler only needed it to read its own files in /etc. However this is not confirmed, and it may need read access to etc_t afteral. Also i would like to underscore my reason for using public_content_rw_t. One of the reasons is that i do not want to give cobbler access to manage httpd_sys_content_rw_t. In general i do not want to depend on apache module at all.

trunk: Unified labeled networking policy from Paul Moore. The latest revision of the labeled policy patches which enable both labeled and unlabeled policy support for NetLabel. This revision takes into account Chris' feedback from the first version and reduces the number of interface calls in each domain down to two at present: one for unlabeled access, one for NetLabel access. The older, transport layer specific interfaces, are still present for use by third-party modules but are not used in the default policy modules. trunk: Use netmsg initial SID for MLS-only Netlabel packets, from Paul Moore. This patch changes the policy to use the netmsg initial SID as the "base" SID/context for NetLabel packets which only have MLS security attributes. Currently we use the unlabeled initial SID which makes it very difficult to distinquish between actual unlabeled packets and those packets which have MLS security attributes. 2007-06-27 15:23:21 +00:00			`corenet_all_recvfrom_unlabeled(dnsmasq_t)`
