6 dcc_client_selinux - Security Enhanced Linux Policy for the dcc_client
7 processes
8
10 Security-Enhanced Linux secures the dcc_client processes via flexible
11 mandatory access control.
12
13 The dcc_client processes execute with the dcc_client_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dcc_client_t
20
21
22
24 The dcc_client_t SELinux type can be entered via the dcc_client_exec_t
25 file type.
26
27 The default entrypoint paths for the dcc_client_t domain are the fol‐
28 lowing:
29
30 /usr/bin/dccproc
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 dcc_client policy is very flexible allowing users to setup their
40 dcc_client processes in as secure a method as possible.
41
42 The following process types are defined for dcc_client:
43
44 dcc_client_t
45
46 Note: semanage permissive -a dcc_client_t can be used to make the
47 process type dcc_client_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 dcc_client policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dcc_client with the tightest
56 access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type dcc_client_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

111 SELinux requires files to have an extended attribute to define the file
112 type.
113
114 You can see the context of a file using the -Z option to ls
115
116 Policy governs the access confined processes have to these files.
117 SELinux dcc_client policy is very flexible allowing users to setup
118 their dcc_client processes in as secure a method as possible.
119
120 STANDARD FILE CONTEXT
121
122 SELinux defines the file context types for the dcc_client, if you
123 wanted to store files with these types in a diffent paths, you need to
124 execute the semanage command to specify alternate labeling and then use
125 restorecon to put the labels on disk.
126
127 semanage fcontext -a -t dcc_client_tmp_t '/srv/mydcc_client_con‐
128 tent(/.*)?'
129 restorecon -R -v /srv/mydcc_client_content
130
131 Note: SELinux often uses regular expressions to specify labels that
132 match multiple files.
133
134 The following file types are defined for dcc_client:
135
136
137
138 dcc_client_exec_t
139
140 - Set files with the dcc_client_exec_t type, if you want to transition
141 an executable to the dcc_client_t domain.
142
143
144
145 dcc_client_map_t
146
147 - Set files with the dcc_client_map_t type, if you want to treat the
148 files as dcc client map data.
149
150
151 Paths:
152 /etc/dcc/map, /var/dcc/map, /var/lib/dcc/map, /var/run/dcc/map
153
154
155 dcc_client_tmp_t
156
157 - Set files with the dcc_client_tmp_t type, if you want to store dcc
158 client temporary files in the /tmp directories.
159
160
161
162 Note: File context can be temporarily modified with the chcon command.
163 If you want to permanently change the file context you need to use the
164 semanage fcontext command. This will modify the SELinux labeling data‐
165 base. You will need to use restorecon to apply the labels.
166
167
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171
172 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174
175 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177
178 semanage boolean can also be used to manipulate the booleans
179
180
181 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
