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 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 For example:
18 ps -eZ | grep dcc_dbclean_t
20
24 The dcc_dbclean_t SELinux type can be entered via the
25 dcc_dbclean_exec_t file type.
26 The default entrypoint paths for the dcc_dbclean_t domain are the fol‐
28 lowing:
29 /usr/libexec/dcc/dbclean
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 dcc_dbclean policy is very flexible allowing users to setup their
40 dcc_dbclean processes in as secure a method as possible.
41 The following process types are defined for dcc_dbclean:
43 dcc_dbclean_t
45 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
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.
57 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112 setsebool -P nscd_use_shm 1
114
118 The SELinux process type dcc_dbclean_t can manage files labeled with
119 the following file types. The paths listed are the default paths for
120 these file types. Note the processes UID still need to have DAC per‐
121 missions.
122 dcc_client_map_t

126 /var/dcc/map

167 SELinux requires files to have an extended attribute to define the file
168 type.
169 You can see the context of a file using the -Z option to ls
171 Policy governs the access confined processes have to these files.
173 SELinux dcc_dbclean policy is very flexible allowing users to setup
174 their dcc_dbclean processes in as secure a method as possible.
175 STANDARD FILE CONTEXT
177 SELinux defines the file context types for the dcc_dbclean, if you
179 wanted to store files with these types in a diffent paths, you need to
180 execute the semanage command to sepecify alternate labeling and then
181 use restorecon to put the labels on disk.
182 semanage fcontext -a -t dcc_dbclean_tmp_t '/srv/mydcc_dbclean_con‐
184 tent(/.*)?'
185 restorecon -R -v /srv/mydcc_dbclean_content
186 Note: SELinux often uses regular expressions to specify labels that
188 match multiple files.
189 The following file types are defined for dcc_dbclean:
191 dcc_dbclean_exec_t
195 - Set files with the dcc_dbclean_exec_t type, if you want to transition
197 an executable to the dcc_dbclean_t domain.
198 dcc_dbclean_tmp_t
202 - Set files with the dcc_dbclean_tmp_t type, if you want to store dcc
204 dbclean temporary files in the /tmp directories.
205 Note: File context can be temporarily modified with the chcon command.
209 If you want to permanently change the file context you need to use the
210 semanage fcontext command. This will modify the SELinux labeling data‐
211 base. You will need to use restorecon to apply the labels.
212
215 semanage fcontext can also be used to manipulate default file context
216 mappings.
217 semanage permissive can also be used to manipulate whether or not a
219 process type is permissive.
220 semanage module can also be used to enable/disable/install/remove pol‐
222 icy modules.
223 semanage boolean can also be used to manipulate the booleans
225 system-config-selinux is a GUI tool available to customize SELinux pol‐
228 icy settings.
