6 fprintd_selinux - Security Enhanced Linux Policy for the fprintd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the fprintd processes via flexible
11 mandatory access control.
12 The fprintd processes execute with the fprintd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep fprintd_t
20
24 The fprintd_t SELinux type can be entered via the fprintd_exec_t file
25 type.
26 The default entrypoint paths for the fprintd_t domain are the follow‐
28 ing:
29 /usr/libexec/fprintd
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 fprintd policy is very flexible allowing users to setup their fprintd
40 processes in as secure a method as possible.
41 The following process types are defined for fprintd:
43 fprintd_t
45 Note: semanage permissive -a fprintd_t can be used to make the process
47 type fprintd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. fprintd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run fprintd with the tightest access possi‐
56 ble.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1

97 The SELinux process type fprintd_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

145 SELinux requires files to have an extended attribute to define the file
146 type.
147 You can see the context of a file using the -Z option to ls
149 Policy governs the access confined processes have to these files.
151 SELinux fprintd policy is very flexible allowing users to setup their
152 fprintd processes in as secure a method as possible.
153 STANDARD FILE CONTEXT
155 SELinux defines the file context types for the fprintd, if you wanted
157 to store files with these types in a diffent paths, you need to execute
158 the semanage command to sepecify alternate labeling and then use
159 restorecon to put the labels on disk.
160 semanage fcontext -a -t fprintd_tmp_t '/srv/myfprintd_content(/.*)?'
162 restorecon -R -v /srv/myfprintd_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for fprintd:
168 fprintd_exec_t
172 - Set files with the fprintd_exec_t type, if you want to transition an
174 executable to the fprintd_t domain.
175 fprintd_tmp_t
179 - Set files with the fprintd_tmp_t type, if you want to store fprintd
181 temporary files in the /tmp directories.
182 fprintd_var_lib_t
186 - Set files with the fprintd_var_lib_t type, if you want to store the
188 fprintd files under the /var/lib directory.
189 Note: File context can be temporarily modified with the chcon command.
193 If you want to permanently change the file context you need to use the
194 semanage fcontext command. This will modify the SELinux labeling data‐
195 base. You will need to use restorecon to apply the labels.
196
199 semanage fcontext can also be used to manipulate default file context
200 mappings.
201 semanage permissive can also be used to manipulate whether or not a
203 process type is permissive.
204 semanage module can also be used to enable/disable/install/remove pol‐
206 icy modules.
207 semanage boolean can also be used to manipulate the booleans
209 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
