NAME

       pulseaudio_selinux - Security Enhanced Linux Policy for the pulseaudio processes

DESCRIPTION

       Security-Enhanced Linux secures the pulseaudio processes via flexible mandatory access control.

       The  pulseaudio processes execute with the pulseaudio_t SELinux type. You can check if you have these processes running by executing the ps
       command with the -Z qualifier.

       For example:

       ps -eZ | grep pulseaudio_t

ENTRYPOINTS

       The pulseaudio_t SELinux type can be entered via the pulseaudio_exec_t file type.

       The default entrypoint paths for the pulseaudio_t domain are the following:

       /usr/bin/pulseaudio

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 pulseaudio policy is very  flexible  allowing  users  to  setup  their
       pulseaudio processes in as secure a method as possible.

       The following process types are defined for pulseaudio:

       pulseaudio_t

       Note:  semanage	permissive  -a	pulseaudio_t can be used to make the process type pulseaudio_t permissive. SELinux does not deny access to
       permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

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

       If  you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or debugging any other processes, you must  turn  on  the	deny_ptrace  boolean.  Enabled	by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want  to  allow  all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

       setsebool -P nscd_use_shm 1

       If you want to allow regular users direct dri device access, you must  turn  on	the  selinuxuser_direct_dri_enabled  boolean.  Enabled	by
       default.

       setsebool -P selinuxuser_direct_dri_enabled 1

       If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.

       setsebool -P use_nfs_home_dirs 1

       If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

       setsebool -P use_samba_home_dirs 1

       If  you	want  to  allows clients to write to the X server shared memory segments, you must turn on the xserver_clients_write_xshm boolean.
       Disabled by default.

       setsebool -P xserver_clients_write_xshm 1

       If you want to support X userspace object manager, you must turn on the xserver_object_manager boolean. Enabled by default.

       setsebool -P xserver_object_manager 1

NSSWITCH DOMAIN

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the pulseaudio_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 pulseaudio_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

PORT TYPES

       SELinux defines port types to represent TCP and UDP ports.

       You can see the types associated with a port by using the following command:

       semanage port -l

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

       The following port types are defined for pulseaudio:

       pulseaudio_port_t

       Default Defined Ports:
		 tcp 4713
		 udp 4713

MANAGED FILES

       The SELinux process type pulseaudio_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.

       anon_inodefs_t

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 pulseaudio policy is very flexible allowing users to setup their
       pulseaudio processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the pulseaudio, if you wanted to store files with these types in a diffent paths,  you  need	to
       execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t pulseaudio_exec_t '/srv/pulseaudio/content(/.*)?'
       restorecon -R -v /srv/mypulseaudio_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for pulseaudio:

       pulseaudio_exec_t

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

       pulseaudio_home_t

       - Set files with the pulseaudio_home_t type, if you want to store pulseaudio files in the users home directory.

       Paths:
	    /root/.pulse(/.*)?,   /root/.config/pulse(/.*)?,  /root/.esd_auth,	/root/.pulse-cookie,  /home/[^/]*/.pulse(/.*)?,  /home/[^/]*/.con-
	    fig/pulse(/.*)?, /home/[^/]*/.esd_auth, /home/[^/]*/.pulse-cookie

       pulseaudio_tmpfs_t

       - Set files with the pulseaudio_tmpfs_t type, if you want to store pulseaudio files on a tmpfs file system.

       pulseaudio_var_lib_t

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

       pulseaudio_var_run_t

       - Set files with the pulseaudio_var_run_t type, if you want to store the pulseaudio files under the /run or /var/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.

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 policy modules.

       semanage port can also be used to manipulate the port definitions

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
