DESCRIPTION
Security-Enhanced Linux secures the afs processes via flexible manda‐
tory access control.
NSSWITCH DOMAINFILE 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/local(/.*)?, /usr/afs/etc(/.*)?
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 permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. 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:
udp 7007
afs_client_port_t
Default Defined Ports:
udp 7001
afs_fs_port_t
Default Defined Ports:
tcp 2040
udp 7000,7005
afs_ka_port_t
Default Defined Ports:
udp 7004
afs_pt_port_t
Default Defined Ports:
udp 7002
afs_vl_port_t
Default Defined Ports:
udp 7003
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.
