Security-Enhanced Linux secures the privoxy processes via flexible mandatory access control.
If you want to allow privoxy to connect to all ports, not just HTTP, FTP, and Gopher ports, you must turn on the privoxy_connect_any boolean.
setsebool -P privoxy_connect_any 1
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the privoxy_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the privoxy_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux privoxy policy is very flexible allowing users to setup their privoxy processes in as secure a method as possible.
The following file types are defined for privoxy:
privoxy_etc_rw_t
- Set files with the privoxy_etc_rw_t type, if you want to treat the files as privoxy etc read/write content.
privoxy_exec_t
- Set files with the privoxy_exec_t type, if you want to transition an executable to the privoxy_t domain.
privoxy_initrc_exec_t
- Set files with the privoxy_initrc_exec_t type, if you want to transition an executable to the privoxy_initrc_t domain.
privoxy_log_t
- Set files with the privoxy_log_t type, if you want to treat the data as privoxy log data, usually stored under the /var/log directory.
privoxy_var_run_t
- Set files with the privoxy_var_run_t type, if you want to store the privoxy files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux privoxy policy is very flexible allowing users to setup their privoxy processes in as secure a method as possible.
The following process types are defined for privoxy:
privoxy_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
The SELinux user type privoxy_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
privoxy_etc_rw_t
/etc/privoxy/[^/]*.action
privoxy_log_t
/var/log/privoxy(/.*)?
privoxy_var_run_t
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy
