6 xenconsoled_selinux - Security Enhanced Linux Policy for the xencon‐
7 soled processes
8
10 Security-Enhanced Linux secures the xenconsoled processes via flexible
11 mandatory access control.
12 The xenconsoled processes execute with the xenconsoled_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep xenconsoled_t
20
24 The xenconsoled_t SELinux type can be entered via the xencon‐
25 soled_exec_t file type.
26 The default entrypoint paths for the xenconsoled_t domain are the fol‐
28 lowing:
29 /usr/sbin/xenconsoled
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 xenconsoled policy is very flexible allowing users to setup their xen‐
40 consoled processes in as secure a method as possible.
41 The following process types are defined for xenconsoled:
43 xenconsoled_t
45 Note: semanage permissive -a xenconsoled_t can be used to make the
47 process type xenconsoled_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. xencon‐
54 soled policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run xenconsoled with the tightest
56 access possible.

98 ean. Enabled by default.

101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

142 The SELinux process type xenconsoled_t can manage files labeled with
143 the following file types. The paths listed are the default paths for
144 these file types. Note the processes UID still need to have DAC per‐
145 missions.

202 SELinux requires files to have an extended attribute to define the file
203 type.
204 You can see the context of a file using the -Z option to ls
206 Policy governs the access confined processes have to these files.
208 SELinux xenconsoled policy is very flexible allowing users to setup
209 their xenconsoled processes in as secure a method as possible.
210 STANDARD FILE CONTEXT
212 SELinux defines the file context types for the xenconsoled, if you
214 wanted to store files with these types in a diffent paths, you need to
215 execute the semanage command to sepecify alternate labeling and then
216 use restorecon to put the labels on disk.
217 semanage fcontext -a -t xenconsoled_var_run_t '/srv/myxenconsoled_con‐
219 tent(/.*)?'
220 restorecon -R -v /srv/myxenconsoled_content
221 Note: SELinux often uses regular expressions to specify labels that
223 match multiple files.
224 The following file types are defined for xenconsoled:
226 xenconsoled_exec_t
230 - Set files with the xenconsoled_exec_t type, if you want to transition
232 an executable to the xenconsoled_t domain.
233 xenconsoled_var_run_t
237 - Set files with the xenconsoled_var_run_t type, if you want to store
239 the xenconsoled files under the /run or /var/run directory.
240 Note: File context can be temporarily modified with the chcon command.
244 If you want to permanently change the file context you need to use the
245 semanage fcontext command. This will modify the SELinux labeling data‐
246 base. You will need to use restorecon to apply the labels.
247
250 semanage fcontext can also be used to manipulate default file context
251 mappings.
252 semanage permissive can also be used to manipulate whether or not a
254 process type is permissive.
255 semanage module can also be used to enable/disable/install/remove pol‐
257 icy modules.
258 semanage boolean can also be used to manipulate the booleans
260 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
