avahi_selinux(8)      avahi SELinux Policy documentation      avahi_selinux(8)

NAME
       avahi_selinux - Security Enhanced Linux Policy for the avahi processes

DESCRIPTION
       Security-Enhanced Linux secures the avahi processes via flexible manda‐
       tory access control.

BOOLEANS
       SELinux policy is customizable based on least access  required.	 avahi
       policy is extremely flexible and has several booleans that allow you to
       manipulate the policy and run avahi with the tightest access possible.

       If you want to allow Apache to communicate with avahi service via  dbu,
       you must turn on the httpd_dbus_avahi boolean.

       setsebool -P httpd_dbus_avahi 1

NSSWITCH DOMAIN
       If you want to allow users to login using a sssd serve for the avahi_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
       avahi_t, you must turn on the allow_kerberos boolean.

       setsebool -P allow_kerberos 1

       If  you	want  to allow system to run with NI for the avahi_t, you must
       turn on the allow_ypbind boolean.

       setsebool -P allow_ypbind 1

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy  governs	the  access  confined  processes  have to these files.
       SELinux avahi policy is very flexible allowing  users  to  setup	 their
       avahi processes in as secure a method as possible.

       The following file types are defined for avahi:

       avahi_exec_t

       -  Set  files  with the avahi_exec_t type, if you want to transition an
       executable to the avahi_t domain.

       Paths:
	    /usr/sbin/avahi-dnsconfd,		      /usr/sbin/avahi-autoipd,
	    /usr/sbin/avahi-daemon

       avahi_initrc_exec_t

       -  Set  files with the avahi_initrc_exec_t type, if you want to transi‐
       tion an executable to the avahi_initrc_t domain.

       avahi_unit_file_t

       - Set files with the avahi_unit_file_t type, if you want to  treat  the
       files as avahi unit content.

       avahi_var_lib_t

       -  Set  files  with  the avahi_var_lib_t type, if you want to store the
       avahi files under the /var/lib directory.

       avahi_var_run_t

       - Set files with the avahi_var_run_t type, if you  want	to  store  the
       avahi files under the /run directory.

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanantly change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy  governs	the  access confined processes have to files.  SELinux
       avahi policy is very flexible allowing users to setup their avahi  pro‐
       cesses in as secure a method as possible.

       The following process types are defined for avahi:

       avahi_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.

COMMANDS
       semanage	 fcontext  can also be used to manipulate default file context
       mappings.

       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 pol‐
       icy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
