NAME afs_selinux - Security Enhanced Linux Policy for the afs processes

DESCRIPTION SELinux Linux secures afs (Andrew Filesystem server) 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 ls

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

The following file types are defined for afs:

afs_bosserver_exec_t

- Set files with the afs_bosserver_exec_t type, if you want to transi- tion an executable to the afs_bosserver_t domain.

afs_cache_t

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

Paths: /var/cache/afs(/.*)?, /usr/vice/cache(/.*)?

afs_config_t

- Set files with the afs_config_t type, if you want to treat the files as afs configuration data, usually stored under the /etc directory.

Paths: /usr/afs/etc(/.*)?, /usr/afs/local(/.*)?

afs_dbdir_t

- Set files with the afs_dbdir_t type, if you want to treat the files as afs dbdir data.

afs_exec_t

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

Paths: /usr/vice/etc/afsd, /usr/sbin/afsd

afs_files_t

- Set files with the afs_files_t type, if you want to treat the files as afs content.

Paths: /vicepc, /vicepb, /vicepa

afs_fsserver_exec_t

- Set files with the afs_fsserver_exec_t type, if you want to transi- tion an executable to the afs_fsserver_t domain.

Paths: /usr/afs/bin/volserver, /usr/afs/bin/fileserver, /usr/afs/bin/sal- vager

afs_initrc_exec_t

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

Paths: /etc/rc.d/init.d/afs, /etc/rc.d/init.d/openafs-client

afs_ka_db_t

- Set files with the afs_ka_db_t type, if you want to treat the files as afs ka database content.

afs_kaserver_exec_t

- Set files with the afs_kaserver_exec_t type, if you want to transi- tion an executable to the afs_kaserver_t domain.

afs_logfile_t

- Set files with the afs_logfile_t type, if you want to treat the files as afs logfile data.

afs_pt_db_t

- Set files with the afs_pt_db_t type, if you want to treat the files as afs pt database content.

afs_ptserver_exec_t

- Set files with the afs_ptserver_exec_t type, if you want to transi- tion an executable to the afs_ptserver_t domain.

afs_vl_db_t

- Set files with the afs_vl_db_t type, if you want to treat the files as afs vl database content.

afs_vlserver_exec_t

- Set files with the afs_vlserver_exec_t type, if you want to transi- tion an executable to the afs_vlserver_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.

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

The following port types are defined for afs:

afs_bos_port_t

Default Defined Ports: tcp 8021

afs_client_port_t

Default Defined Ports: tcp 8021

afs_fs_port_t

Default Defined Ports: tcp 8021

afs_ka_port_t

Default Defined Ports: tcp 8021

afs_pt_port_t

Default Defined Ports: tcp 8021

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

The following process types are defined for afs:

afs_kaserver_t, afs_t, afs_fsserver_t, afs_bosserver_t, afs_vlserver_t, afs_ptserver_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

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