entropyd_selinux(8)SELinux Policy documentation for entropyentropyd_selinux(8)

NAME entropyd_selinux - Security Enhanced Linux Policy for the entropyd pro- cesses

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

The entropyd processes execute with the entropyd_t SELinux type. You can check if you have these processes running by executing the ps com- mand with the -Z qualifier.

For example:

ps -eZ | grep entropyd_t

ENTRYPOINTS The entropyd_t SELinux type can be entered via the "entropyd_exec_t" file type. The default entrypoint paths for the entropyd_t domain are the following:"

/usr/sbin/audio-entropyd

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

The following process types are defined for entropyd:

entropyd_t

Note: semanage permissive -a entropyd_t

can be used to make the process type entropyd_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 entropyd policy is very flexible allowing users to setup their entropyd processes in as secure a method as possible.

The following file types are defined for entropyd:

entropyd_exec_t

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

entropyd_var_run_t

- Set files with the entropyd_var_run_t type, if you want to store the entropyd 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.

MANAGED FILES The SELinux process type entropyd_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.

entropyd_var_run_t

/var/run/audio-entropyd.pid

initrc_tmp_t

mnt_t

/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev

root_t

/ /initrd

tmp_t

/tmp /usr/tmp /var/tmp /var/tmp/vi.recover

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.

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