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.

114 SELinux requires files to have an extended attribute to define the file
115 type.
116
117 You can see the context of a file using the -Z option to ls
118
119 Policy governs the access confined processes have to these files.
120 SELinux uuidd policy is very flexible allowing users to setup their
121 uuidd processes in as secure a method as possible.
122
123 STANDARD FILE CONTEXT
124
125 SELinux defines the file context types for the uuidd, if you wanted to
126 store files with these types in a diffent paths, you need to execute
127 the semanage command to specify alternate labeling and then use re‐
128 storecon to put the labels on disk.
129
130 semanage fcontext -a -t uuidd_var_run_t '/srv/myuuidd_content(/.*)?'
131 restorecon -R -v /srv/myuuidd_content
132
133 Note: SELinux often uses regular expressions to specify labels that
134 match multiple files.
135
136 The following file types are defined for uuidd:
137
138
139
140 uuidd_exec_t
141
142 - Set files with the uuidd_exec_t type, if you want to transition an
143 executable to the uuidd_t domain.
144
145
146
147 uuidd_initrc_exec_t
148
149 - Set files with the uuidd_initrc_exec_t type, if you want to transi‐
150 tion an executable to the uuidd_initrc_t domain.
151
152
153
154 uuidd_var_lib_t
155
156 - Set files with the uuidd_var_lib_t type, if you want to store the
157 uuidd files under the /var/lib directory.
158
159
160
161 uuidd_var_run_t
162
163 - Set files with the uuidd_var_run_t type, if you want to store the
164 uuidd files under the /run or /var/run directory.
165
166
167
168 Note: File context can be temporarily modified with the chcon command.
169 If you want to permanently change the file context you need to use the
170 semanage fcontext command. This will modify the SELinux labeling data‐
171 base. You will need to use restorecon to apply the labels.
172
173
175 semanage fcontext can also be used to manipulate default file context
176 mappings.
177
178 semanage permissive can also be used to manipulate whether or not a
179 process type is permissive.
180
181 semanage module can also be used to enable/disable/install/remove pol‐
182 icy modules.
183
184 semanage boolean can also be used to manipulate the booleans
185
186
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
188 icy settings.
