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 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 For example:
17 ps -eZ | grep uuidd_t
19
23 The uuidd_t SELinux type can be entered via the uuidd_exec_t file type.
24 The default entrypoint paths for the uuidd_t domain are the following:
26 /usr/sbin/uuidd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for uuidd:
40 uuidd_t
42 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
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 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59 setsebool -P daemons_dontaudit_scheduling 1
61 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 setsebool -P fips_mode 1
68
72 The SELinux process type uuidd_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

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