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 dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

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

150 SELinux requires files to have an extended attribute to define the file
151 type.
152 You can see the context of a file using the -Z option to ls
154 Policy governs the access confined processes have to these files.
156 SELinux fprintd policy is very flexible allowing users to setup their
157 fprintd processes in as secure a method as possible.
158 STANDARD FILE CONTEXT
160 SELinux defines the file context types for the fprintd, if you wanted
162 to store files with these types in a different paths, you need to exe‐
163 cute the semanage command to specify alternate labeling and then use
164 restorecon to put the labels on disk.
165 semanage fcontext -a -t fprintd_exec_t '/srv/fprintd/content(/.*)?'
167 restorecon -R -v /srv/myfprintd_content
168 Note: SELinux often uses regular expressions to specify labels that
170 match multiple files.
171 The following file types are defined for fprintd:
173 fprintd_exec_t
177 - Set files with the fprintd_exec_t type, if you want to transition an
179 executable to the fprintd_t domain.
180 fprintd_tmp_t
184 - Set files with the fprintd_tmp_t type, if you want to store fprintd
186 temporary files in the /tmp directories.
187 fprintd_var_lib_t
191 - Set files with the fprintd_var_lib_t type, if you want to store the
193 fprintd files under the /var/lib directory.
194 Note: File context can be temporarily modified with the chcon command.
198 If you want to permanently change the file context you need to use the
199 semanage fcontext command. This will modify the SELinux labeling data‐
200 base. You will need to use restorecon to apply the labels.
201
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
