6 getty_selinux - Security Enhanced Linux Policy for the getty processes
7
9 Security-Enhanced Linux secures the getty processes via flexible manda‐
10 tory access control.
11 The getty processes execute with the getty_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 getty_t
19
23 The getty_t SELinux type can be entered via the getty_exec_t file type.
24 The default entrypoint paths for the getty_t domain are the following:
26 /sbin/.*getty, /usr/sbin/.*getty
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 getty policy is very flexible allowing users to setup their getty pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for getty:
40 getty_t
42 Note: semanage permissive -a getty_t can be used to make the process
44 type getty_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. getty
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run getty 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 logging in and using the system from /dev/console,
64 you must turn on the login_console_enabled boolean. Enabled by default.
65 setsebool -P login_console_enabled 1
67 If you want to allow system to run with NIS, you must turn on the
71 nis_enabled boolean. Disabled by default.
72 setsebool -P nis_enabled 1
74
78 The SELinux process type getty_t can manage files labeled with the fol‐
79 lowing file types. The paths listed are the default paths for these
80 file types. Note the processes UID still need to have DAC permissions.

140 SELinux requires files to have an extended attribute to define the file
141 type.
142 You can see the context of a file using the -Z option to ls
144 Policy governs the access confined processes have to these files.
146 SELinux getty policy is very flexible allowing users to setup their
147 getty processes in as secure a method as possible.
148 STANDARD FILE CONTEXT
150 SELinux defines the file context types for the getty, if you wanted to
152 store files with these types in a different paths, you need to execute
153 the semanage command to specify alternate labeling and then use re‐
154 storecon to put the labels on disk.
155 semanage fcontext -a -t getty_exec_t '/srv/getty/content(/.*)?'
157 restorecon -R -v /srv/mygetty_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for getty:
163 getty_etc_t
167 - Set files with the getty_etc_t type, if you want to store getty files
169 in the /etc directories.
170 getty_exec_t
174 - Set files with the getty_exec_t type, if you want to transition an
176 executable to the getty_t domain.
177 Paths:
180 /sbin/.*getty, /usr/sbin/.*getty
181 getty_lock_t
184 - Set files with the getty_lock_t type, if you want to treat the files
186 as getty lock data, stored under the /var/lock directory
187 getty_log_t
191 - Set files with the getty_log_t type, if you want to treat the data as
193 getty log data, usually stored under the /var/log directory.
194 Paths:
197 /var/log/mgetty.*.log.*, /var/log/vgetty.*.log.*
198 getty_tmp_t
201 - Set files with the getty_tmp_t type, if you want to store getty tem‐
203 porary files in the /tmp directories.
204 getty_unit_file_t
208 - Set files with the getty_unit_file_t type, if you want to treat the
210 files as getty unit content.
211 getty_var_run_t
215 - Set files with the getty_var_run_t type, if you want to store the
217 getty files under the /run or /var/run directory.
218 Paths:
221 /var/spool/fax(/.*)?, /var/spool/voice(/.*)?,
222 /var/run/mgetty.pid.*, /var/run/agetty.reload.*
223 Note: File context can be temporarily modified with the chcon command.
226 If you want to permanently change the file context you need to use the
227 semanage fcontext command. This will modify the SELinux labeling data‐
228 base. You will need to use restorecon to apply the labels.
229
232 semanage fcontext can also be used to manipulate default file context
233 mappings.
234 semanage permissive can also be used to manipulate whether or not a
236 process type is permissive.
237 semanage module can also be used to enable/disable/install/remove pol‐
239 icy modules.
240 semanage boolean can also be used to manipulate the booleans
242 system-config-selinux is a GUI tool available to customize SELinux pol‐
245 icy settings.
