pulseaudio_selinux(8) - Linux man page

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,user_home_t" file types. The default entrypoint paths for the pulseaudio_t domain are the following:"

/usr/bin/pulseaudio, /home/[^/]*/.+

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. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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.

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.

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 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.

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.

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

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