6 uuidd_selinux - Security Enhanced Linux Policy for the uuidd processes
7
9 Security-Enhanced Linux secures the uuidd processes via flexible manda‐
10 tory access control.
11
12 The uuidd processes execute with the uuidd_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 uuidd_t
19
20
21
23 The uuidd_t SELinux type can be entered via the uuidd_exec_t file type.
24
25 The default entrypoint paths for the uuidd_t domain are the following:
26
27 /usr/sbin/uuidd
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 uuidd policy is very flexible allowing users to setup their uuidd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for uuidd:
40
41 uuidd_t
42
43 Note: semanage permissive -a uuidd_t can be used to make the process
44 type uuidd_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. uuidd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run uuidd with the tightest access possible.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
64 The SELinux process type uuidd_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.

113 SELinux requires files to have an extended attribute to define the file
114 type.
115
116 You can see the context of a file using the -Z option to ls
117
118 Policy governs the access confined processes have to these files.
119 SELinux uuidd policy is very flexible allowing users to setup their
120 uuidd processes in as secure a method as possible.
121
122 STANDARD FILE CONTEXT
123
124 SELinux defines the file context types for the uuidd, if you wanted to
125 store files with these types in a diffent paths, you need to execute
126 the semanage command to sepecify alternate labeling and then use
127 restorecon to put the labels on disk.
128
129 semanage fcontext -a -t uuidd_var_run_t '/srv/myuuidd_content(/.*)?'
130 restorecon -R -v /srv/myuuidd_content
131
132 Note: SELinux often uses regular expressions to specify labels that
133 match multiple files.
134
135 The following file types are defined for uuidd:
136
137
138
139 uuidd_exec_t
140
141 - Set files with the uuidd_exec_t type, if you want to transition an
142 executable to the uuidd_t domain.
143
144
145
146 uuidd_initrc_exec_t
147
148 - Set files with the uuidd_initrc_exec_t type, if you want to transi‐
149 tion an executable to the uuidd_initrc_t domain.
150
151
152
153 uuidd_var_lib_t
154
155 - Set files with the uuidd_var_lib_t type, if you want to store the
156 uuidd files under the /var/lib directory.
157
158
159
160 uuidd_var_run_t
161
162 - Set files with the uuidd_var_run_t type, if you want to store the
163 uuidd files under the /run or /var/run directory.
164
165
166
167 Note: File context can be temporarily modified with the chcon command.
168 If you want to permanently change the file context you need to use the
169 semanage fcontext command. This will modify the SELinux labeling data‐
170 base. You will need to use restorecon to apply the labels.
171
172
174 semanage fcontext can also be used to manipulate default file context
175 mappings.
176
177 semanage permissive can also be used to manipulate whether or not a
178 process type is permissive.
179
180 semanage module can also be used to enable/disable/install/remove pol‐
181 icy modules.
182
183 semanage boolean can also be used to manipulate the booleans
184
185
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
187 icy settings.
