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/sbin/dbclean, /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 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type dcc_dbclean_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101 dcc_client_map_t
103 /etc/dcc/map
105 /var/dcc/map
106 /var/lib/dcc/map
107 /var/run/dcc/map
108 dcc_dbclean_tmp_t
110 dcc_var_t
113 /etc/dcc(/.*)?
115 /var/dcc(/.*)?
116 /var/lib/dcc(/.*)?
117
120 SELinux requires files to have an extended attribute to define the file
121 type.
122 You can see the context of a file using the -Z option to ls
124 Policy governs the access confined processes have to these files.
126 SELinux dcc_dbclean policy is very flexible allowing users to setup
127 their dcc_dbclean processes in as secure a method as possible.
128 STANDARD FILE CONTEXT
130 SELinux defines the file context types for the dcc_dbclean, if you
132 wanted to store files with these types in a diffent paths, you need to
133 execute the semanage command to sepecify alternate labeling and then
134 use restorecon to put the labels on disk.
135 semanage fcontext -a -t dcc_dbclean_tmp_t '/srv/mydcc_dbclean_con‐
137 tent(/.*)?'
138 restorecon -R -v /srv/mydcc_dbclean_content
139 Note: SELinux often uses regular expressions to specify labels that
141 match multiple files.
142 The following file types are defined for dcc_dbclean:
144 dcc_dbclean_exec_t
148 - Set files with the dcc_dbclean_exec_t type, if you want to transition
150 an executable to the dcc_dbclean_t domain.
151 Paths:
154 /usr/sbin/dbclean, /usr/libexec/dcc/dbclean
155 dcc_dbclean_tmp_t
158 - Set files with the dcc_dbclean_tmp_t type, if you want to store dcc
160 dbclean temporary files in the /tmp directories.
161 Note: File context can be temporarily modified with the chcon command.
165 If you want to permanently change the file context you need to use the
166 semanage fcontext command. This will modify the SELinux labeling data‐
167 base. You will need to use restorecon to apply the labels.
168
171 semanage fcontext can also be used to manipulate default file context
172 mappings.
173 semanage permissive can also be used to manipulate whether or not a
175 process type is permissive.
176 semanage module can also be used to enable/disable/install/remove pol‐
178 icy modules.
179 semanage boolean can also be used to manipulate the booleans
181 system-config-selinux is a GUI tool available to customize SELinux pol‐
184 icy settings.
