NAME cvs_selinux - Security Enhanced Linux Policy for the cvs processes

DESCRIPTION SELinux Linux secures cvs (Concurrent versions system) processes via flexible mandatory access control.

BOOLEANS SELinux policy is customizable based on least access required. cvs policy is extremely flexible and has several booleans that allow you to manipulate the policy and run cvs with the tightest access possible.

If you want to allow cvs daemon to read shado, you must turn on the allow_cvs_read_shadow boolean.

setsebool -P allow_cvs_read_shadow 1

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

The following file types are defined for cvs:

cvs_data_t

- Set files with the cvs_data_t type, if you want to treat the files as cvs content.

Paths: /opt/cvs(/.*)?, /var/cvs(/.*)?

cvs_exec_t

- Set files with the cvs_exec_t type, if you want to transition an exe- cutable to the cvs_t domain.

cvs_initrc_exec_t

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

cvs_keytab_t

- Set files with the cvs_keytab_t type, if you want to treat the files as kerberos keytab files.

cvs_tmp_t

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

cvs_var_run_t

- Set files with the cvs_var_run_t type, if you want to store the cvs 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.

PORT TYPES SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for cvs:

cvs_port_t

Default Defined Ports: tcp 8021

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

The following process types are defined for cvs:

cvs_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 pol- icy modules.

semanage port can also be used to manipulate the port definitions

semanage boolean can also be used to manipulate the booleans

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