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 all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the allow_kerberos boolean. Enabled by default.
77 setsebool -P allow_kerberos 1
79 If you want to allow sysadm to debug or ptrace all processes, you must
83 turn on the allow_ptrace boolean. Disabled by default.
84 setsebool -P allow_ptrace 1
86 If you want to allow system to run with NIS, you must turn on the
90 allow_ypbind boolean. Disabled by default.
91 setsebool -P allow_ypbind 1
93 If you want to allow all domains to have the kernel load modules, you
97 must turn on the domain_kernel_load_modules boolean. Disabled by
98 default.
99 setsebool -P domain_kernel_load_modules 1
101 If you want to allow all domains to execute in fips_mode, you must turn
105 on the fips_mode boolean. Enabled by default.
106 setsebool -P fips_mode 1
108 If you want to enable reading of urandom for all domains, you must turn
112 on the global_ssp boolean. Disabled by default.
113 setsebool -P global_ssp 1
115 If you want to allow confined applications to use nscd shared memory,
119 you must turn on the nscd_use_shm boolean. Enabled by default.
120 setsebool -P nscd_use_shm 1
122
126 The SELinux process type fprintd_t can manage files labeled with the
127 following file types. The paths listed are the default paths for these
128 file types. Note the processes UID still need to have DAC permissions.
129 fprintd_var_lib_t
131 /var/lib/fprint(/.*)?
133 initrc_tmp_t
135 mnt_t
138 /mnt(/[^/]*)
140 /mnt(/[^/]*)?
141 /rhev(/[^/]*)?
142 /media(/[^/]*)
143 /media(/[^/]*)?
144 /etc/rhgb(/.*)?
145 /media/.hal-.*
146 /net
147 /afs
148 /rhev
149 /misc
150 tmp_t
152 /tmp
154 /usr/tmp
155 /var/tmp
156 /tmp-inst
157 /var/tmp-inst
158 /var/tmp/vi.recover
159
162 SELinux requires files to have an extended attribute to define the file
163 type.
164 You can see the context of a file using the -Z option to ls
166 Policy governs the access confined processes have to these files.
168 SELinux fprintd policy is very flexible allowing users to setup their
169 fprintd processes in as secure a method as possible.
170 STANDARD FILE CONTEXT
172 SELinux defines the file context types for the fprintd, if you wanted
174 to store files with these types in a diffent paths, you need to execute
175 the semanage command to sepecify alternate labeling and then use
176 restorecon to put the labels on disk.
177 semanage fcontext -a -t fprintd_var_lib_t '/srv/myfprintd_con‐
179 tent(/.*)?'
180 restorecon -R -v /srv/myfprintd_content
181 Note: SELinux often uses regular expressions to specify labels that
183 match multiple files.
184 The following file types are defined for fprintd:
186 fprintd_exec_t
190 - Set files with the fprintd_exec_t type, if you want to transition an
192 executable to the fprintd_t domain.
193 fprintd_var_lib_t
197 - Set files with the fprintd_var_lib_t type, if you want to store the
199 fprintd files under the /var/lib directory.
200 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
