locate_selinux(8) - Linux man page
Name
locate_selinux - Security Enhanced Linux Policy for the locate processes
Description
Security-Enhanced Linux secures the locate processes via flexible mandatory access control.
The locate processes execute with the locate_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 locate_t
Entrypoints
The locate_t SELinux type can be entered via the "locate_exec_t" file type. The default entrypoint paths for the locate_t domain are the following:"
/usr/bin/updatedb
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 locate policy is very flexible allowing users to setup their locate processes in as secure a method as possible.
The following process types are defined for locate:
locate_t
Note: semanage permissive -a locate_t
can be used to make the process type locate_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 locate policy is very flexible allowing users to setup their locate processes in as secure a method as possible.
The following file types are defined for locate:
locate_exec_t
- Set files with the locate_exec_t type, if you want to transition an executable to the locate_t domain.
locate_log_t
- Set files with the locate_log_t type, if you want to treat the data as locate log data, usually stored under the /var/log directory.
locate_var_lib_t
- Set files with the locate_var_lib_t type, if you want to store the locate files under the /var/lib 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 locate_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.
initrc_tmp_t
locate_var_lib_t
/var/lib/[sm]locate(/.*)?
- mnt_t
/mnt(/[^/]*)
/mnt(/[^/]*)?
/rhev(/[^/]*)?
/media(/[^/]*)
/media(/[^/]*)?
/etc/rhgb(/.*)?
/media/.hal-.*
/net
/afs
/misc
/rhev
- 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 policy modules.
system-config-selinux is a GUI tool available to customize SELinux policy settings.
