6 xauth_selinux - Security Enhanced Linux Policy for the xauth processes
7
9 Security-Enhanced Linux secures the xauth processes via flexible manda‐
10 tory access control.
11 The xauth processes execute with the xauth_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 xauth_t
19
23 The xauth_t SELinux type can be entered via the xauth_exec_t file type.
24 The default entrypoint paths for the xauth_t domain are the following:
26 /usr/bin/xauth, /usr/X11R6/bin/xauth
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 xauth policy is very flexible allowing users to setup their xauth pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for xauth:
40 xauth_t
42 Note: semanage permissive -a xauth_t can be used to make the process
44 type xauth_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. xauth
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run xauth with the tightest access possible.
53 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 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 The SELinux process type xauth_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149 You can see the context of a file using the -Z option to ls
151 Policy governs the access confined processes have to these files.
153 SELinux xauth policy is very flexible allowing users to setup their
154 xauth processes in as secure a method as possible.
155 STANDARD FILE CONTEXT
157 SELinux defines the file context types for the xauth, if you wanted to
159 store files with these types in a diffent paths, you need to execute
160 the semanage command to sepecify alternate labeling and then use re‐
161 storecon to put the labels on disk.
162 semanage fcontext -a -t xauth_tmp_t '/srv/myxauth_content(/.*)?'
164 restorecon -R -v /srv/myxauth_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for xauth:
170 xauth_exec_t
174 - Set files with the xauth_exec_t type, if you want to transition an
176 executable to the xauth_t domain.
177 Paths:
180 /usr/bin/xauth, /usr/X11R6/bin/xauth
181 xauth_home_t
184 - Set files with the xauth_home_t type, if you want to store xauth
186 files in the users home directory.
187 Paths:
190 /root/.Xauth.*, /root/.xauth.*, /root/.Xauthority.*,
191 /root/.serverauth.*, /var/lib/pqsql/.xauth.*, /var/lib/pqsql/.Xau‐
192 thority.*, /var/lib/nxserver/home/.xauth.*,
193 /var/lib/nxserver/home/.Xauthority.*, /home/[^/]+/.Xauth.*,
194 /home/[^/]+/.xauth.*, /home/[^/]+/.Xauthority.*,
195 /home/[^/]+/.serverauth.*
196 xauth_tmp_t
199 - Set files with the xauth_tmp_t type, if you want to store xauth tem‐
201 porary files in the /tmp directories.
202 Note: File context can be temporarily modified with the chcon command.
206 If you want to permanently change the file context you need to use the
207 semanage fcontext command. This will modify the SELinux labeling data‐
208 base. You will need to use restorecon to apply the labels.
209
212 semanage fcontext can also be used to manipulate default file context
213 mappings.
214 semanage permissive can also be used to manipulate whether or not a
216 process type is permissive.
217 semanage module can also be used to enable/disable/install/remove pol‐
219 icy modules.
220 semanage boolean can also be used to manipulate the booleans
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
