ricci_modclusterd_selinSELinux Policy ricci_modcluricci_modclusterd_selinux(8)NAMEricci_modclusterd_selinux - Security Enhanced Linux Policy for the
ricci_modclusterd processes
DESCRIPTION
Security-Enhanced Linux secures the ricci_modclusterd processes via
flexible mandatory access control.
The ricci_modclusterd processes execute with the ricci_modclusterd_t
SELinux type. You can check if you have these processes running by exe‐
cuting the ps command with the -Z qualifier.
For example:
ps -eZ | grep ricci_modclusterd_t
ENTRYPOINTS
The ricci_modclusterd_t SELinux type can be entered via the ricci_mod‐
clusterd_exec_t file type.
The default entrypoint paths for the ricci_modclusterd_t domain are the
following:
/usr/sbin/modclusterd
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
ricci_modclusterd policy is very flexible allowing users to setup their
ricci_modclusterd processes in as secure a method as possible.
The following process types are defined for ricci_modclusterd:
ricci_modclusterd_t, ricci_modcluster_t
Note: semanage permissive -a ricci_modclusterd_t can be used to make
the process type ricci_modclusterd_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux denials) mes‐
sages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required.
ricci_modclusterd policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run ricci_modclusterd with
the tightest access possible.
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server, you must turn on the authlo‐
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow all daemons to write corefiles to /, you must turn
on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the
daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on
the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals,
you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors,
you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you
must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn
on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn
on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow confined applications to run with kerberos, you
must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory,
you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server for the ricci_modcluster_t,
ricci_modclusterd_t, you must turn on the authlogin_nsswitch_use_ldap
boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
ricci_modcluster_t, ricci_modclusterd_t, you must turn on the ker‐
beros_enabled boolean.
setsebool -P kerberos_enabled 1
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 ricci_modclusterd policy is very flexible allowing users to
setup their ricci_modclusterd processes in as secure a method as possi‐
ble.
The following port types are defined for ricci_modclusterd:
ricci_modcluster_port_t
Default Defined Ports:
tcp 16851
udp 16851
MANAGED FILES
The SELinux process type ricci_modclusterd_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.
cluster_conf_t
/etc/cluster(/.*)?
cluster_var_lib_t
/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?

/initrd
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 ricci_modclusterd policy is very flexible allowing users to
setup their ricci_modclusterd processes in as secure a method as possi‐
ble.
STANDARD FILE CONTEXT
SELinux defines the file context types for the ricci_modclusterd, if
you wanted to store files with these types in a diffent paths, you need
to execute the semanage command to sepecify alternate labeling and then
use restorecon to put the labels on disk.
semanage fcontext -a -t ricci_modclusterd_exec_t '/srv/ricci_modclus‐
terd/content(/.*)?'
restorecon -R -v /srv/myricci_modclusterd_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for ricci_modclusterd:
ricci_modclusterd_exec_t
- Set files with the ricci_modclusterd_exec_t type, if you want to
transition an executable to the ricci_modclusterd_t domain.
ricci_modclusterd_tmpfs_t
- Set files with the ricci_modclusterd_tmpfs_t type, if you want to
store ricci modclusterd files on a tmpfs file system.
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 data‐
base. You will need to use restorecon to apply the labels.
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.
