6 automount_selinux - Security Enhanced Linux Policy for the automount
7 processes
8
10 Security-Enhanced Linux secures the automount processes via flexible
11 mandatory access control.
12 The automount processes execute with the automount_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 automount_t
20
24 The automount_t SELinux type can be entered via the automount_exec_t
25 file type.
26 The default entrypoint paths for the automount_t domain are the follow‐
28 ing:
29 /usr/sbin/automount, /etc/apm/event.d/autofs
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 automount policy is very flexible allowing users to setup their auto‐
40 mount processes in as secure a method as possible.
41 The following process types are defined for automount:
43 automount_t
45 Note: semanage permissive -a automount_t can be used to make the
47 process type automount_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. auto‐
54 mount policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run automount 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 If you want to allow the mount commands to mount any directory or file,
68 you must turn on the mount_anyfile boolean. Disabled by default.
69 setsebool -P mount_anyfile 1
71
75 The SELinux process type automount_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

132 SELinux requires files to have an extended attribute to define the file
133 type.
134 You can see the context of a file using the -Z option to ls
136 Policy governs the access confined processes have to these files.
138 SELinux automount policy is very flexible allowing users to setup their
139 automount processes in as secure a method as possible.
140 STANDARD FILE CONTEXT
142 SELinux defines the file context types for the automount, if you wanted
144 to store files with these types in a diffent paths, you need to execute
145 the semanage command to sepecify alternate labeling and then use
146 restorecon to put the labels on disk.
147 semanage fcontext -a -t automount_var_run_t '/srv/myautomount_con‐
149 tent(/.*)?'
150 restorecon -R -v /srv/myautomount_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for automount:
156 automount_exec_t
160 - Set files with the automount_exec_t type, if you want to transition
162 an executable to the automount_t domain.
163 Paths:
166 /usr/sbin/automount, /etc/apm/event.d/autofs
167 automount_initrc_exec_t
170 - Set files with the automount_initrc_exec_t type, if you want to tran‐
172 sition an executable to the automount_initrc_t domain.
173 automount_keytab_t
177 - Set files with the automount_keytab_t type, if you want to treat the
179 files as kerberos keytab files.
180 automount_lock_t
184 - Set files with the automount_lock_t type, if you want to treat the
186 files as automount lock data, stored under the /var/lock directory
187 automount_tmp_t
191 - Set files with the automount_tmp_t type, if you want to store auto‐
193 mount temporary files in the /tmp directories.
194 automount_unit_file_t
198 - Set files with the automount_unit_file_t type, if you want to treat
200 the files as automount unit content.
201 automount_var_run_t
205 - Set files with the automount_var_run_t type, if you want to store the
207 automount files under the /run or /var/run directory.
208 Note: File context can be temporarily modified with the chcon command.
212 If you want to permanently change the file context you need to use the
213 semanage fcontext command. This will modify the SELinux labeling data‐
214 base. You will need to use restorecon to apply the labels.
215
218 semanage fcontext can also be used to manipulate default file context
219 mappings.
220 semanage permissive can also be used to manipulate whether or not a
222 process type is permissive.
223 semanage module can also be used to enable/disable/install/remove pol‐
225 icy modules.
226 semanage boolean can also be used to manipulate the booleans
228 system-config-selinux is a GUI tool available to customize SELinux pol‐
231 icy settings.
