6 dcc_dbclean_selinux - Security Enhanced Linux Policy for the
7 dcc_dbclean processes
8
10 Security-Enhanced Linux secures the dcc_dbclean processes via flexible
11 mandatory access control.
12
13 The dcc_dbclean processes execute with the dcc_dbclean_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_dbclean_t
20
21
22
24 The dcc_dbclean_t SELinux type can be entered via the
25 dcc_dbclean_exec_t file type.
26
27 The default entrypoint paths for the dcc_dbclean_t domain are the fol‐
28 lowing:
29
30 /usr/sbin/dbclean, /usr/libexec/dcc/dbclean
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_dbclean policy is very flexible allowing users to setup their
40 dcc_dbclean processes in as secure a method as possible.
41
42 The following process types are defined for dcc_dbclean:
43
44 dcc_dbclean_t
45
46 Note: semanage permissive -a dcc_dbclean_t can be used to make the
47 process type dcc_dbclean_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_dbclean policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dcc_dbclean with the tight‐
56 est access possible.

58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.

73
74
75
76 If you want to allow any process to mmap any file on system with

78 ean. Enabled by default.

81
82
83
84 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87
88 setsebool -P domain_can_write_kmsg 1
89
90
91
92 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94
95 setsebool -P domain_fd_use 1
96
97
98
99 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102
103 setsebool -P domain_kernel_load_modules 1
104
105
106
107 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109
110 setsebool -P fips_mode 1
111
112
113
114 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116
117 setsebool -P global_ssp 1
118
119
120
121 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123
124 setsebool -P kerberos_enabled 1
125
126
127
128 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130
131 setsebool -P nis_enabled 1
132
133
134
135 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137
138 setsebool -P nscd_use_shm 1
139
140
141
143 The SELinux process type dcc_dbclean_t can manage files labeled with
144 the following file types. The paths listed are the default paths for
145 these file types. Note the processes UID still need to have DAC per‐
146 missions.
147
148 dcc_client_map_t
149
150 /etc/dcc/map
151 /var/dcc/map
152 /var/lib/dcc/map
153 /var/run/dcc/map
154
155 dcc_dbclean_tmp_t
156
157
158 dcc_var_t
159
160 /etc/dcc(/.*)?
161 /var/dcc(/.*)?
162 /var/lib/dcc(/.*)?
163
164
166 SELinux requires files to have an extended attribute to define the file
167 type.
168
169 You can see the context of a file using the -Z option to ls
170
171 Policy governs the access confined processes have to these files.
172 SELinux dcc_dbclean policy is very flexible allowing users to setup
173 their dcc_dbclean processes in as secure a method as possible.
174
175 STANDARD FILE CONTEXT
176
177 SELinux defines the file context types for the dcc_dbclean, if you
178 wanted to store files with these types in a diffent paths, you need to
179 execute the semanage command to sepecify alternate labeling and then
180 use restorecon to put the labels on disk.
181
182 semanage fcontext -a -t dcc_dbclean_tmp_t '/srv/mydcc_dbclean_con‐
183 tent(/.*)?'
184 restorecon -R -v /srv/mydcc_dbclean_content
185
186 Note: SELinux often uses regular expressions to specify labels that
187 match multiple files.
188
189 The following file types are defined for dcc_dbclean:
190
191
192
193 dcc_dbclean_exec_t
194
195 - Set files with the dcc_dbclean_exec_t type, if you want to transition
196 an executable to the dcc_dbclean_t domain.
197
198
199 Paths:
200 /usr/sbin/dbclean, /usr/libexec/dcc/dbclean
201
202
203 dcc_dbclean_tmp_t
204
205 - Set files with the dcc_dbclean_tmp_t type, if you want to store dcc
206 dbclean temporary files in the /tmp directories.
207
208
209
210 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
215
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219
220 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222
223 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225
226 semanage boolean can also be used to manipulate the booleans
227
228
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
