6 hwloc_dhwd_selinux - Security Enhanced Linux Policy for the hwloc_dhwd
7 processes
8
10 Security-Enhanced Linux secures the hwloc_dhwd processes via flexible
11 mandatory access control.
12
13 The hwloc_dhwd processes execute with the hwloc_dhwd_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 hwloc_dhwd_t
20
21
22
24 The hwloc_dhwd_t SELinux type can be entered via the hwloc_dhwd_exec_t
25 file type.
26
27 The default entrypoint paths for the hwloc_dhwd_t domain are the fol‐
28 lowing:
29
30 /usr/sbin/hwloc-dump-hwdata
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 hwloc_dhwd policy is very flexible allowing users to setup their
40 hwloc_dhwd processes in as secure a method as possible.
41
42 The following process types are defined for hwloc_dhwd:
43
44 hwloc_dhwd_t
45
46 Note: semanage permissive -a hwloc_dhwd_t can be used to make the
47 process type hwloc_dhwd_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 hwloc_dhwd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run hwloc_dhwd with the tightest
56 access possible.
57
58
59
60 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the daemons_use_tty boolean. Disabled by default.
62
63 setsebool -P daemons_use_tty 1
64
65
66
67 If you want to deny any process from ptracing or debugging any other
68 processes, you must turn on the deny_ptrace boolean. Enabled by
69 default.
70
71 setsebool -P deny_ptrace 1
72
73
74
75 If you want to allow any process to mmap any file on system with
76 attribute file_type, you must turn on the domain_can_mmap_files bool‐
77 ean. Enabled by default.
78
79 setsebool -P domain_can_mmap_files 1
80
81
82
83 If you want to allow all domains write to kmsg_device, while kernel is
84 executed with systemd.log_target=kmsg parameter, you must turn on the
85 domain_can_write_kmsg boolean. Disabled by default.
86
87 setsebool -P domain_can_write_kmsg 1
88
89
90
91 If you want to allow all domains to use other domains file descriptors,
92 you must turn on the domain_fd_use boolean. Enabled by default.
93
94 setsebool -P domain_fd_use 1
95
96
97
98 If you want to allow all domains to have the kernel load modules, you
99 must turn on the domain_kernel_load_modules boolean. Disabled by
100 default.
101
102 setsebool -P domain_kernel_load_modules 1
103
104
105
106 If you want to allow all domains to execute in fips_mode, you must turn
107 on the fips_mode boolean. Enabled by default.
108
109 setsebool -P fips_mode 1
110
111
112
113 If you want to enable reading of urandom for all domains, you must turn
114 on the global_ssp boolean. Disabled by default.
115
116 setsebool -P global_ssp 1
117
118
119
121 The SELinux process type hwloc_dhwd_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.
124
125 hwloc_var_run_t
126
127 /var/run/hwloc(/.*)?
128
129
131 SELinux requires files to have an extended attribute to define the file
132 type.
133
134 You can see the context of a file using the -Z option to ls
135
136 Policy governs the access confined processes have to these files.
137 SELinux hwloc_dhwd policy is very flexible allowing users to setup
138 their hwloc_dhwd processes in as secure a method as possible.
139
140 STANDARD FILE CONTEXT
141
142 SELinux defines the file context types for the hwloc_dhwd, if you
143 wanted to store files with these types in a diffent paths, you need to
144 execute the semanage command to sepecify alternate labeling and then
145 use restorecon to put the labels on disk.
146
147 semanage fcontext -a -t hwloc_dhwd_unit_t '/srv/myhwloc_dhwd_con‐
148 tent(/.*)?'
149 restorecon -R -v /srv/myhwloc_dhwd_content
150
151 Note: SELinux often uses regular expressions to specify labels that
152 match multiple files.
153
154 The following file types are defined for hwloc_dhwd:
155
156
157
158 hwloc_dhwd_exec_t
159
160 - Set files with the hwloc_dhwd_exec_t type, if you want to transition
161 an executable to the hwloc_dhwd_t domain.
162
163
164
165 hwloc_dhwd_unit_t
166
167 - Set files with the hwloc_dhwd_unit_t type, if you want to treat the
168 files as hwloc dhwd unit data.
169
170
171
172 Note: File context can be temporarily modified with the chcon command.
173 If you want to permanently change the file context you need to use the
174 semanage fcontext command. This will modify the SELinux labeling data‐
175 base. You will need to use restorecon to apply the labels.
176
177
179 semanage fcontext can also be used to manipulate default file context
180 mappings.
181
182 semanage permissive can also be used to manipulate whether or not a
183 process type is permissive.
184
185 semanage module can also be used to enable/disable/install/remove pol‐
186 icy modules.
187
188 semanage boolean can also be used to manipulate the booleans
189
190
191 system-config-selinux is a GUI tool available to customize SELinux pol‐
192 icy settings.
