6 dccifd_selinux - Security Enhanced Linux Policy for the dccifd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the dccifd processes via flexible
11 mandatory access control.
12 The dccifd processes execute with the dccifd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep dccifd_t
20
24 The dccifd_t SELinux type can be entered via the dccifd_exec_t file
25 type.
26 The default entrypoint paths for the dccifd_t domain are the following:
28 /usr/sbin/dccifd, /usr/libexec/dcc/dccifd, /usr/libexec/dcc/start-
30 dccifd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 dccifd policy is very flexible allowing users to setup their dccifd
40 processes in as secure a method as possible.
41 The following process types are defined for dccifd:
43 dccifd_t
45 Note: semanage permissive -a dccifd_t can be used to make the process
47 type dccifd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. dccifd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run dccifd with the tightest access possible.
56 If you want to allow users to resolve user passwd entries directly from
60 ldap rather then using a sssd server, you must turn on the authlo‐
61 gin_nsswitch_use_ldap boolean. Disabled by default.
62 setsebool -P authlogin_nsswitch_use_ldap 1
64 If you want to allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69 setsebool -P fips_mode 1
71 If you want to allow confined applications to run with kerberos, you
75 must turn on the kerberos_enabled boolean. Disabled by default.
76 setsebool -P kerberos_enabled 1
78 If you want to allow system to run with NIS, you must turn on the
82 nis_enabled boolean. Disabled by default.
83 setsebool -P nis_enabled 1
85 If you want to allow confined applications to use nscd shared memory,
89 you must turn on the nscd_use_shm boolean. Disabled by default.
90 setsebool -P nscd_use_shm 1

96 The SELinux process type dccifd_t can manage files labeled with the
97 following file types. The paths listed are the default paths for these
98 file types. Note the processes UID still need to have DAC permissions.

158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux dccifd policy is very flexible allowing users to setup their
165 dccifd processes in as secure a method as possible.
166 STANDARD FILE CONTEXT
168 SELinux defines the file context types for the dccifd, if you wanted to
170 store files with these types in a diffent paths, you need to execute
171 the semanage command to sepecify alternate labeling and then use
172 restorecon to put the labels on disk.
173 semanage fcontext -a -t dccifd_var_run_t '/srv/mydccifd_content(/.*)?'
175 restorecon -R -v /srv/mydccifd_content
176 Note: SELinux often uses regular expressions to specify labels that
178 match multiple files.
179 The following file types are defined for dccifd:
181 dccifd_exec_t
185 - Set files with the dccifd_exec_t type, if you want to transition an
187 executable to the dccifd_t domain.
188 Paths:
191 /usr/sbin/dccifd, /usr/libexec/dcc/dccifd, /usr/libexec/dcc/start-
192 dccifd
193 dccifd_tmp_t
196 - Set files with the dccifd_tmp_t type, if you want to store dccifd
198 temporary files in the /tmp directories.
199 dccifd_var_run_t
203 - Set files with the dccifd_var_run_t type, if you want to store the
205 dccifd files under the /run or /var/run directory.
206 Paths:
209 /etc/dcc/dccifd, /var/run/dcc/dccifd
210 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
