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.

130 SELinux requires files to have an extended attribute to define the file
131 type.
132 You can see the context of a file using the -Z option to ls
134 Policy governs the access confined processes have to these files.
136 SELinux xauth policy is very flexible allowing users to setup their
137 xauth processes in as secure a method as possible.
138 STANDARD FILE CONTEXT
140 SELinux defines the file context types for the xauth, if you wanted to
142 store files with these types in a diffent paths, you need to execute
143 the semanage command to sepecify alternate labeling and then use
144 restorecon to put the labels on disk.
145 semanage fcontext -a -t xauth_tmp_t '/srv/myxauth_content(/.*)?'
147 restorecon -R -v /srv/myxauth_content
148 Note: SELinux often uses regular expressions to specify labels that
150 match multiple files.
151 The following file types are defined for xauth:
153 xauth_exec_t
157 - Set files with the xauth_exec_t type, if you want to transition an
159 executable to the xauth_t domain.
160 Paths:
163 /usr/bin/xauth, /usr/X11R6/bin/xauth
164 xauth_home_t
167 - Set files with the xauth_home_t type, if you want to store xauth
169 files in the users home directory.
170 Paths:
173 /root/.Xauth.*, /root/.xauth.*, /root/.Xauthority.*,
174 /root/.serverauth.*, /var/lib/pqsql/.xauth.*, /var/lib/pqsql/.Xau‐
175 thority.*, /var/lib/nxserver/home/.xauth.*,
176 /var/lib/nxserver/home/.Xauthority.*, /home/[^/]+/.Xauth.*,
177 /home/[^/]+/.xauth.*, /home/[^/]+/.Xauthority.*,
178 /home/[^/]+/.serverauth.*
179 xauth_tmp_t
182 - Set files with the xauth_tmp_t type, if you want to store xauth tem‐
184 porary files in the /tmp directories.
185 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
