chfn_selinux(8) SELinux Policy documentation for chfn chfn_selinux(8)

NAME chfn_selinux - Security Enhanced Linux Policy for the chfn processes

DESCRIPTION Security-Enhanced Linux secures the chfn processes via flexible manda- tory access control.

The chfn processes execute with the chfn_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 chfn_t

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

/usr/bin/chfn, /usr/bin/chsh

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 chfn policy is very flexible allowing users to setup their chfn pro- cesses in as secure a method as possible.

The following process types are defined for chfn:

chfn_t

Note: semanage permissive -a chfn_t

can be used to make the process type chfn_t permissive. Permissive pro- cess 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 chfn policy is very flexible allowing users to setup their chfn processes in as secure a method as possible.

The following file types are defined for chfn:

chfn_exec_t

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

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 chfn_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.

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.
