6 load_policy_selinux - Security Enhanced Linux Policy for the load_pol‐
7 icy processes
8
10 Security-Enhanced Linux secures the load_policy processes via flexible
11 mandatory access control.
12
13 The load_policy processes execute with the load_policy_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 load_policy_t
20
21
22
24 The load_policy_t SELinux type can be entered via the load_pol‐
25 icy_exec_t file type.
26
27 The default entrypoint paths for the load_policy_t domain are the fol‐
28 lowing:
29
30 /sbin/load_policy, /usr/sbin/load_policy
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 load_policy policy is very flexible allowing users to setup their
40 load_policy processes in as secure a method as possible.
41
42 The following process types are defined for load_policy:
43
44 load_policy_t
45
46 Note: semanage permissive -a load_policy_t can be used to make the
47 process type load_policy_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 load_policy policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run load_policy with the tight‐
56 est access possible.
57
58
59
60 If you want to deny any process from ptracing or debugging any other
61 processes, you must turn on the deny_ptrace boolean. Enabled by
62 default.
63
64 setsebool -P deny_ptrace 1
65
66
67
68 If you want to allow any process to mmap any file on system with
69 attribute file_type, you must turn on the domain_can_mmap_files bool‐
70 ean. Enabled by default.
71
72 setsebool -P domain_can_mmap_files 1
73
74
75
76 If you want to allow all domains write to kmsg_device, while kernel is
77 executed with systemd.log_target=kmsg parameter, you must turn on the
78 domain_can_write_kmsg boolean. Disabled by default.
79
80 setsebool -P domain_can_write_kmsg 1
81
82
83
84 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the domain_fd_use boolean. Enabled by default.
86
87 setsebool -P domain_fd_use 1
88
89
90
91 If you want to allow all domains to have the kernel load modules, you
92 must turn on the domain_kernel_load_modules boolean. Disabled by
93 default.
94
95 setsebool -P domain_kernel_load_modules 1
96
97
98
99 If you want to allow all domains to execute in fips_mode, you must turn
100 on the fips_mode boolean. Enabled by default.
101
102 setsebool -P fips_mode 1
103
104
105
106 If you want to enable reading of urandom for all domains, you must turn
107 on the global_ssp boolean. Disabled by default.
108
109 setsebool -P global_ssp 1
110
111
112
113 If you want to boolean to determine whether the system permits loading
114 policy, setting enforcing mode, and changing boolean values. Set this
115 to true and you have to reboot to set it back, you must turn on the
116 secure_mode_policyload boolean. Enabled by default.
117
118 setsebool -P secure_mode_policyload 1
119
120
121
123 The SELinux process type load_policy_t can manage files labeled with
124 the following file types. The paths listed are the default paths for
125 these file types. Note the processes UID still need to have DAC per‐
126 missions.
127
128 boolean_type
129
130
131
133 SELinux requires files to have an extended attribute to define the file
134 type.
135
136 You can see the context of a file using the -Z option to ls
137
138 Policy governs the access confined processes have to these files.
139 SELinux load_policy policy is very flexible allowing users to setup
140 their load_policy processes in as secure a method as possible.
141
142 The following file types are defined for load_policy:
143
144
145
146 load_policy_exec_t
147
148 - Set files with the load_policy_exec_t type, if you want to transition
149 an executable to the load_policy_t domain.
150
151
152 Paths:
153 /sbin/load_policy, /usr/sbin/load_policy
154
155
156 Note: File context can be temporarily modified with the chcon command.
157 If you want to permanently change the file context you need to use the
158 semanage fcontext command. This will modify the SELinux labeling data‐
159 base. You will need to use restorecon to apply the labels.
160
161
163 semanage fcontext can also be used to manipulate default file context
164 mappings.
165
166 semanage permissive can also be used to manipulate whether or not a
167 process type is permissive.
168
169 semanage module can also be used to enable/disable/install/remove pol‐
170 icy modules.
171
172 semanage boolean can also be used to manipulate the booleans
173
174
175 system-config-selinux is a GUI tool available to customize SELinux pol‐
176 icy settings.
