virt_qemu_ga_selinux(8) - Linux man page

Name

virt_qemu_ga_selinux - Security Enhanced Linux Policy for the virt_qemu_ga processes

Description

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

The virt_qemu_ga processes execute with the virt_qemu_ga_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 virt_qemu_ga_t

Entrypoints

The virt_qemu_ga_t SELinux type can be entered via the "virt_qemu_ga_exec_t" file type. The default entrypoint paths for the virt_qemu_ga_t domain are the following:"

/usr/bin/qemu-ga

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

The following process types are defined for virt_qemu_ga:

virt_qemu_ga_t

Note: semanage permissive -a virt_qemu_ga_t

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

The following file types are defined for virt_qemu_ga:

virt_qemu_ga_exec_t

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

virt_qemu_ga_log_t

- Set files with the virt_qemu_ga_log_t type, if you want to treat the data as virt qemu ga log data, usually stored under the /var/log directory.

virt_qemu_ga_var_run_t

- Set files with the virt_qemu_ga_var_run_t type, if you want to store the virt qemu ga 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 virt_qemu_ga_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.

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