6 xenstored_selinux - Security Enhanced Linux Policy for the xenstored
7 processes
8
10 Security-Enhanced Linux secures the xenstored processes via flexible
11 mandatory access control.
12 The xenstored processes execute with the xenstored_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep xenstored_t
20
24 The xenstored_t SELinux type can be entered via the xenstored_exec_t
25 file type.
26 The default entrypoint paths for the xenstored_t domain are the follow‐
28 ing:
29 /usr/sbin/xenstored, /usr/sbin/oxenstored, /etc/xen/scripts/launch-xen‐
31 store
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 xenstored policy is very flexible allowing users to setup their xen‐
41 stored processes in as secure a method as possible.
42 The following process types are defined for xenstored:
44 xenstored_t
46 Note: semanage permissive -a xenstored_t can be used to make the
48 process type xenstored_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. xen‐
55 stored policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run xenstored with the tightest access
57 possible.
58 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63 setsebool -P fips_mode 1
65 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70 setsebool -P nis_enabled 1
72
76 The SELinux process type xenstored_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

133 SELinux requires files to have an extended attribute to define the file
134 type.
135 You can see the context of a file using the -Z option to ls
137 Policy governs the access confined processes have to these files.
139 SELinux xenstored policy is very flexible allowing users to setup their
140 xenstored processes in as secure a method as possible.
141 STANDARD FILE CONTEXT
143 SELinux defines the file context types for the xenstored, if you wanted
145 to store files with these types in a diffent paths, you need to execute
146 the semanage command to sepecify alternate labeling and then use
147 restorecon to put the labels on disk.
148 semanage fcontext -a -t xenstored_var_run_t '/srv/myxenstored_con‐
150 tent(/.*)?'
151 restorecon -R -v /srv/myxenstored_content
152 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155 The following file types are defined for xenstored:
157 xenstored_exec_t
161 - Set files with the xenstored_exec_t type, if you want to transition
163 an executable to the xenstored_t domain.
164 Paths:
167 /usr/sbin/xenstored, /usr/sbin/oxenstored,
168 /etc/xen/scripts/launch-xenstore
169 xenstored_tmp_t
172 - Set files with the xenstored_tmp_t type, if you want to store xen‐
174 stored temporary files in the /tmp directories.
175 xenstored_var_lib_t
179 - Set files with the xenstored_var_lib_t type, if you want to store the
181 xenstored files under the /var/lib directory.
182 xenstored_var_log_t
186 - Set files with the xenstored_var_log_t type, if you want to treat the
188 data as xenstored var log data, usually stored under the /var/log
189 directory.
190 xenstored_var_run_t
194 - Set files with the xenstored_var_run_t type, if you want to store the
196 xenstored files under the /run or /var/run directory.
197 Paths:
200 /var/run/xenstored(/.*)?, /var/run/xenstore.pid
201 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
