ricci_selinux: Security Enhanced Linux Policy for the ricci processes
NAME
ricci_selinux - Security Enhanced Linux Policy for the ricci processesDESCRIPTION
Security-Enhanced Linux secures the ricci processes via flexible mandatory access control.
The ricci processes execute with the ricci_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep ricci_t
ENTRYPOINTS
The ricci_t SELinux type can be entered via the bin_t, ricci_exec_t, usr_t file types.
The default entrypoint paths for the ricci_t domain are the following:
All executeables with the default executable label, usually stored in /usr/bin and /usr/sbin. /usr/sbin/ricci, /usr/.*, /opt/.*, /emul/.*, /ostree(/.*)?, /export(/.*)?, /usr/doc(/.*)?/lib(/.*)?, /usr/inclu.e(/.*)?, /usr/share/doc(/.*)?/README.*, /usr, /opt, /emul
PROCESS TYPES
SELinux defines process types (domains) for each process running on the systemYou can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux ricci policy is very flexible allowing users to setup their ricci processes in as secure a method as possible.
The following process types are defined for ricci:
ricci_t, ricci_modcluster_t, ricci_modclusterd_t, ricci_modlog_t, ricci_modrpm_t, ricci_modservice_t, ricci_modstorage_t
Note: semanage permissive -a ricci_t can be used to make the process type ricci_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. ricci policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ricci 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 authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 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
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 policy is very flexible allowing users to setup their ricci processes in as secure a method as possible.
The following port types are defined for ricci:
- ricci_modcluster_port_t
-
Default Defined Ports: tcp 16851 udp 16851
- ricci_port_t
-
Default Defined Ports: tcp 11111 udp 11111
MANAGED FILES
The SELinux process type ricci_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
cluster_var_lib_t
cluster_var_run_t
etc_runtime_t
faillog_t
ricci_tmp_t
ricci_var_lib_t
ricci_var_run_t
root_t
systemd_passwd_var_run_t
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 ricci policy is very flexible allowing users to setup their ricci processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the ricci, 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_var_run_t '/srv/myricci_content(/.*)?'
restorecon -R -v /srv/myricci_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for ricci:
ricci_exec_t
- Set files with the ricci_exec_t type, if you want to transition an executable to the ricci_t domain.
ricci_initrc_exec_t
- Set files with the ricci_initrc_exec_t type, if you want to transition an executable to the ricci_initrc_t domain.
ricci_modcluster_exec_t
- Set files with the ricci_modcluster_exec_t type, if you want to transition an executable to the ricci_modcluster_t domain.
ricci_modcluster_var_lib_t
- Set files with the ricci_modcluster_var_lib_t type, if you want to store the ricci modcluster files under the /var/lib directory.
ricci_modcluster_var_log_t
- Set files with the ricci_modcluster_var_log_t type, if you want to treat the data as ricci modcluster var log data, usually stored under the /var/log directory.
ricci_modcluster_var_run_t
- Set files with the ricci_modcluster_var_run_t type, if you want to store the ricci modcluster files under the /run or /var/run directory.
- Paths:
-
/var/run/clumond.sock, /var/run/modclusterd.pid
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.
ricci_modlog_exec_t
- Set files with the ricci_modlog_exec_t type, if you want to transition an executable to the ricci_modlog_t domain.
ricci_modrpm_exec_t
- Set files with the ricci_modrpm_exec_t type, if you want to transition an executable to the ricci_modrpm_t domain.
ricci_modservice_exec_t
- Set files with the ricci_modservice_exec_t type, if you want to transition an executable to the ricci_modservice_t domain.
ricci_modstorage_exec_t
- Set files with the ricci_modstorage_exec_t type, if you want to transition an executable to the ricci_modstorage_t domain.
ricci_modstorage_lock_t
- Set files with the ricci_modstorage_lock_t type, if you want to treat the files as ricci modstorage lock data, stored under the /var/lock directory
ricci_tmp_t
- Set files with the ricci_tmp_t type, if you want to store ricci temporary files in the /tmp directories.
ricci_var_lib_t
- Set files with the ricci_var_lib_t type, if you want to store the ricci files under the /var/lib directory.
ricci_var_log_t
- Set files with the ricci_var_log_t type, if you want to treat the data as ricci var log data, usually stored under the /var/log directory.
ricci_var_run_t
- Set files with the ricci_var_run_t type, if you want to store the ricci files under the /run or /var/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.
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.
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 policy settings.
