NAME

6       cdcc_selinux - Security Enhanced Linux Policy for the cdcc processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the cdcc processes via flexible manda‐
10       tory access control.
11
12       The cdcc processes execute with the cdcc_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep cdcc_t

21

ENTRYPOINTS

23       The cdcc_t SELinux type can be entered via the cdcc_exec_t file type.
24
25       The default entrypoint paths for the cdcc_t domain are the following:
26
27       /usr/bin/cdcc
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       cdcc policy is very flexible allowing users to setup  their  cdcc  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for cdcc:
40
41       cdcc_t
42
43       Note:  semanage  permissive  -a  cdcc_t can be used to make the process
44       type cdcc_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.

48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   cdcc
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run cdcc with the tightest access possible.
53
54
55
56       If you want to allow users to resolve user passwd entries directly from
57       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
58       gin_nsswitch_use_ldap boolean. Disabled by default.
59
60       setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you  want  to allow confined applications to run with kerberos, you
72       must turn on the kerberos_enabled boolean. Enabled by default.
73
74       setsebool -P kerberos_enabled 1
75
76
77
78       If you want to allow system to run with  NIS,  you  must  turn  on  the
79       nis_enabled boolean. Disabled by default.
80
81       setsebool -P nis_enabled 1
82
83
84
85       If  you  want to allow confined applications to use nscd shared memory,
86       you must turn on the nscd_use_shm boolean. Disabled by default.
87
88       setsebool -P nscd_use_shm 1

MANAGED FILES

93       The SELinux process type cdcc_t can manage files labeled with the  fol‐
94       lowing  file  types.   The paths listed are the default paths for these
95       file types.  Note the processes UID still need to have DAC permissions.
96
97       cdcc_tmp_t
98
99
100       dcc_client_map_t
101
102            /etc/dcc/map
103            /var/dcc/map
104            /var/lib/dcc/map
105            /var/run/dcc/map

107

FILE CONTEXTS

109       SELinux requires files to have an extended attribute to define the file
110       type.
111
112       You can see the context of a file using the -Z option to ls
113
114       Policy  governs  the  access  confined  processes  have to these files.
115       SELinux cdcc policy is very flexible allowing users to setup their cdcc
116       processes in as secure a method as possible.
117
118       STANDARD FILE CONTEXT
119
120       SELinux  defines  the file context types for the cdcc, if you wanted to
121       store files with these types in a diffent paths, you  need  to  execute
122       the  semanage  command  to  sepecify  alternate  labeling  and then use
123       restorecon to put the labels on disk.
124
125       semanage fcontext -a -t cdcc_tmp_t '/srv/mycdcc_content(/.*)?'
126       restorecon -R -v /srv/mycdcc_content
127
128       Note: SELinux often uses regular expressions  to  specify  labels  that
129       match multiple files.
130
131       The following file types are defined for cdcc:
132
133
134
135       cdcc_exec_t
136
137       -  Set  files  with  the cdcc_exec_t type, if you want to transition an
138       executable to the cdcc_t domain.
139
140
141
142       cdcc_tmp_t
143
144       - Set files with the cdcc_tmp_t type, if you want to store cdcc  tempo‐
145       rary files in the /tmp directories.
146
147
148
149       Note:  File context can be temporarily modified with the chcon command.
150       If you want to permanently change the file context you need to use  the
151       semanage fcontext command.  This will modify the SELinux labeling data‐
152       base.  You will need to use restorecon to apply the labels.
153
154

COMMANDS

156       semanage fcontext can also be used to manipulate default  file  context
157       mappings.
158
159       semanage  permissive  can  also  be used to manipulate whether or not a
160       process type is permissive.
161
162       semanage module can also be used to enable/disable/install/remove  pol‐
163       icy modules.
164
165       semanage boolean can also be used to manipulate the booleans
166
167
168       system-config-selinux is a GUI tool available to customize SELinux pol‐
169       icy settings.
