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
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 xenstored policy is very flexible allowing users to setup their xen‐
40 stored processes in as secure a method as possible.
41 The following process types are defined for xenstored:
43 xenstored_t
45 Note: semanage permissive -a xenstored_t can be used to make the
47 process type xenstored_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. xen‐
54 stored policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run xenstored with the tightest access
56 possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 The SELinux process type xenstored_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

128 SELinux requires files to have an extended attribute to define the file
129 type.
130 You can see the context of a file using the -Z option to ls
132 Policy governs the access confined processes have to these files.
134 SELinux xenstored policy is very flexible allowing users to setup their
135 xenstored processes in as secure a method as possible.
136 STANDARD FILE CONTEXT
138 SELinux defines the file context types for the xenstored, if you wanted
140 to store files with these types in a diffent paths, you need to execute
141 the semanage command to sepecify alternate labeling and then use
142 restorecon to put the labels on disk.
143 semanage fcontext -a -t xenstored_var_run_t '/srv/myxenstored_con‐
145 tent(/.*)?'
146 restorecon -R -v /srv/myxenstored_content
147 Note: SELinux often uses regular expressions to specify labels that
149 match multiple files.
150 The following file types are defined for xenstored:
152 xenstored_exec_t
156 - Set files with the xenstored_exec_t type, if you want to transition
158 an executable to the xenstored_t domain.
159 Paths:
162 /usr/sbin/xenstored, /usr/sbin/oxenstored
163 xenstored_tmp_t
166 - Set files with the xenstored_tmp_t type, if you want to store xen‐
168 stored temporary files in the /tmp directories.
169 xenstored_var_lib_t
173 - Set files with the xenstored_var_lib_t type, if you want to store the
175 xenstored files under the /var/lib directory.
176 xenstored_var_log_t
180 - Set files with the xenstored_var_log_t type, if you want to treat the
182 data as xenstored var log data, usually stored under the /var/log
183 directory.
184 xenstored_var_run_t
188 - Set files with the xenstored_var_run_t type, if you want to store the
190 xenstored files under the /run or /var/run directory.
191 Paths:
194 /var/run/xenstored(/.*)?, /var/run/xenstore.pid
195 Note: File context can be temporarily modified with the chcon command.
198 If you want to permanently change the file context you need to use the
199 semanage fcontext command. This will modify the SELinux labeling data‐
200 base. You will need to use restorecon to apply the labels.
201
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
