6 cdcc_selinux - Security Enhanced Linux Policy for the cdcc processes
7
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
19
20
21
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
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.
47
48
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 all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68

71 The SELinux process type cdcc_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.
74
75 dcc_client_map_t
76
77 /etc/dcc/map
78 /var/dcc/map
79 /var/lib/dcc/map
80 /var/run/dcc/map
81
82
84 SELinux requires files to have an extended attribute to define the file
85 type.
86
87 You can see the context of a file using the -Z option to ls
88
89 Policy governs the access confined processes have to these files.
90 SELinux cdcc policy is very flexible allowing users to setup their cdcc
91 processes in as secure a method as possible.
92
93 STANDARD FILE CONTEXT
94
95 SELinux defines the file context types for the cdcc, if you wanted to
96 store files with these types in a diffent paths, you need to execute
97 the semanage command to sepecify alternate labeling and then use
98 restorecon to put the labels on disk.
99
100 semanage fcontext -a -t cdcc_tmp_t '/srv/mycdcc_content(/.*)?'
101 restorecon -R -v /srv/mycdcc_content
102
103 Note: SELinux often uses regular expressions to specify labels that
104 match multiple files.
105
106 The following file types are defined for cdcc:
107
108
109
110 cdcc_exec_t
111
112 - Set files with the cdcc_exec_t type, if you want to transition an
113 executable to the cdcc_t domain.
114
115
116
117 cdcc_tmp_t
118
119 - Set files with the cdcc_tmp_t type, if you want to store cdcc tempo‐
120 rary files in the /tmp directories.
121
122
123
124 Note: File context can be temporarily modified with the chcon command.
125 If you want to permanently change the file context you need to use the
126 semanage fcontext command. This will modify the SELinux labeling data‐
127 base. You will need to use restorecon to apply the labels.
128
129
131 semanage fcontext can also be used to manipulate default file context
132 mappings.
133
134 semanage permissive can also be used to manipulate whether or not a
135 process type is permissive.
136
137 semanage module can also be used to enable/disable/install/remove pol‐
138 icy modules.
139
140 semanage boolean can also be used to manipulate the booleans
141
142
143 system-config-selinux is a GUI tool available to customize SELinux pol‐
144 icy settings.
