6 boltd_selinux - Security Enhanced Linux Policy for the boltd processes
7
9 Security-Enhanced Linux secures the boltd processes via flexible manda‐
10 tory access control.
11
12 The boltd processes execute with the boltd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep boltd_t
19
20
21
23 The boltd_t SELinux type can be entered via the boltd_exec_t file type.
24
25 The default entrypoint paths for the boltd_t domain are the following:
26
27 /usr/libexec/boltd
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 boltd policy is very flexible allowing users to setup their boltd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for boltd:
40
41 boltd_t
42
43 Note: semanage permissive -a boltd_t can be used to make the process
44 type boltd_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. boltd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run boltd with the tightest access possible.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 The SELinux process type boltd_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148
149 You can see the context of a file using the -Z option to ls
150
151 Policy governs the access confined processes have to these files.
152 SELinux boltd policy is very flexible allowing users to setup their
153 boltd processes in as secure a method as possible.
154
155 STANDARD FILE CONTEXT
156
157 SELinux defines the file context types for the boltd, if you wanted to
158 store files with these types in a diffent paths, you need to execute
159 the semanage command to sepecify alternate labeling and then use
160 restorecon to put the labels on disk.
161
162 semanage fcontext -a -t boltd_var_run_t '/srv/myboltd_content(/.*)?'
163 restorecon -R -v /srv/myboltd_content
164
165 Note: SELinux often uses regular expressions to specify labels that
166 match multiple files.
167
168 The following file types are defined for boltd:
169
170
171
172 boltd_exec_t
173
174 - Set files with the boltd_exec_t type, if you want to transition an
175 executable to the boltd_t domain.
176
177
178
179 boltd_var_lib_t
180
181 - Set files with the boltd_var_lib_t type, if you want to store the
182 boltd files under the /var/lib directory.
183
184
185
186 boltd_var_run_t
187
188 - Set files with the boltd_var_run_t type, if you want to store the
189 boltd files under the /run or /var/run directory.
190
191
192
193 Note: File context can be temporarily modified with the chcon command.
194 If you want to permanently change the file context you need to use the
195 semanage fcontext command. This will modify the SELinux labeling data‐
196 base. You will need to use restorecon to apply the labels.
197
198
200 semanage fcontext can also be used to manipulate default file context
201 mappings.
202
203 semanage permissive can also be used to manipulate whether or not a
204 process type is permissive.
205
206 semanage module can also be used to enable/disable/install/remove pol‐
207 icy modules.
208
209 semanage boolean can also be used to manipulate the booleans
210
211
212 system-config-selinux is a GUI tool available to customize SELinux pol‐
213 icy settings.
