NAME

prelink_selinux - Security Enhanced Linux Policy for the prelink processes

DESCRIPTION

SELinux Linux secures prelink (Prelink ELF shared library mappings) processes via flexible mandatory access control.

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 lsP Policy governs the access confined processes have to these files. SELinux prelink policy is very flexible allowing users to setup their prelink processes in as secure a method as possible.

The following file types are defined for prelink:

prelink_cache_t

- Set files with the prelink_cache_t type, if you want to store the files under the /var/cache directory.

prelink_cron_system_exec_t

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

prelink_exec_t

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

prelink_log_t

- Set files with the prelink_log_t type, if you want to treat the data as prelink log data, usually stored under the /var/log directory.

Paths:: /var/log/prelink(/.*)?, /var/log/prelink.log

prelink_tmp_t

- Set files with the prelink_tmp_t type, if you want to store prelink temporary files in the /tmp directories.

prelink_tmpfs_t

- Set files with the prelink_tmpfs_t type, if you want to store prelink files on a tmpfs file system.

prelink_var_lib_t

- Set files with the prelink_var_lib_t type, if you want to store the prelink files under the /var/lib directory.

Paths:: /var/lib/prelink(/.*)?, /var/lib/misc/prelink.*

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.

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 psP Policy governs the access confined processes have to files. SELinux prelink policy is very flexible allowing users to setup their prelink processes in as secure a method as possible.

The following process types are defined for prelink:

prelink_cron_system_t, prelink_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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.
