clvmd_selinux(8) SELinux Policy documentation for clvmd clvmd_selinux(8)
NAME clvmd_selinux - Security Enhanced Linux Policy for the clvmd processes
DESCRIPTION Security-Enhanced Linux secures the clvmd processes via flexible manda- tory access control.
The clvmd processes execute with the clvmd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep clvmd_t
ENTRYPOINTS The clvmd_t SELinux type can be entered via the "mtrr_device_t,unla- beled_t,proc_type,sysctl_type,filesystem_type,clvmd_exec_t,file_type" file types. The default entrypoint paths for the clvmd_t domain are the following:"
/dev/cpu/mtrr, /usr/sbin/clvmd, all files on the system
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 clvmd policy is very flexible allowing users to setup their clvmd pro- cesses in as secure a method as possible.
The following process types are defined for clvmd:
Note: semanage permissive -a clvmd_t
can be used to make the process type clvmd_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 clvmd policy is very flexible allowing users to setup their clvmd processes in as secure a method as possible.
The following file types are defined for clvmd:
- Set files with the clvmd_exec_t type, if you want to transition an executable to the clvmd_t domain.
- Set files with the clvmd_initrc_exec_t type, if you want to transi- tion an executable to the clvmd_initrc_t domain.
- Set files with the clvmd_tmpfs_t type, if you want to store clvmd files on a tmpfs file system.
- Set files with the clvmd_var_run_t type, if you want to store the clvmd 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 clvmd_t can manage files labeled with the fol- lowing file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
all files on the system
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.
