6 uucpd_selinux - Security Enhanced Linux Policy for the uucpd processes
7
9 Security-Enhanced Linux secures the uucpd processes via flexible manda‐
10 tory access control.
11 The uucpd processes execute with the uucpd_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 uucpd_t
19
23 The uucpd_t SELinux type can be entered via the uucpd_exec_t file type.
24 The default entrypoint paths for the uucpd_t domain are the following:
26 /usr/sbin/uucico
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 uucpd policy is very flexible allowing users to setup their uucpd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for uucpd:
40 uucpd_t
42 Note: semanage permissive -a uucpd_t can be used to make the process
44 type uucpd_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. uucpd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run uucpd with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59 setsebool -P authlogin_nsswitch_use_ldap 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87 setsebool -P nscd_use_shm 1
89
93 SELinux defines port types to represent TCP and UDP ports.
94 You can see the types associated with a port by using the following
96 command:
97 semanage port -l
99 Policy governs the access confined processes have to these ports.
102 SELinux uucpd policy is very flexible allowing users to setup their
103 uucpd processes in as secure a method as possible.
104 The following port types are defined for uucpd:
106 uucpd_port_t
109 Default Defined Ports:
113 tcp 540
114
116 The SELinux process type uucpd_t can manage files labeled with the fol‐
117 lowing file types. The paths listed are the default paths for these
118 file types. Note the processes UID still need to have DAC permissions.

175 SELinux requires files to have an extended attribute to define the file
176 type.
177 You can see the context of a file using the -Z option to ls
179 Policy governs the access confined processes have to these files.
181 SELinux uucpd policy is very flexible allowing users to setup their
182 uucpd processes in as secure a method as possible.
183 EQUIVALENCE DIRECTORIES
185 uucpd policy stores data with multiple different file context types
188 under the /var/spool/uucp directory. If you would like to store the
189 data in a different directory you can use the semanage command to cre‐
190 ate an equivalence mapping. If you wanted to store this data under the
191 /srv dirctory you would execute the following command:
192 semanage fcontext -a -e /var/spool/uucp /srv/uucp
194 restorecon -R -v /srv/uucp
195 STANDARD FILE CONTEXT
197 SELinux defines the file context types for the uucpd, if you wanted to
199 store files with these types in a diffent paths, you need to execute
200 the semanage command to sepecify alternate labeling and then use
201 restorecon to put the labels on disk.
202 semanage fcontext -a -t uucpd_log_t '/srv/myuucpd_content(/.*)?'
204 restorecon -R -v /srv/myuucpd_content
205 Note: SELinux often uses regular expressions to specify labels that
207 match multiple files.
208 The following file types are defined for uucpd:
210 uucpd_exec_t
214 - Set files with the uucpd_exec_t type, if you want to transition an
216 executable to the uucpd_t domain.
217 uucpd_initrc_exec_t
221 - Set files with the uucpd_initrc_exec_t type, if you want to transi‐
223 tion an executable to the uucpd_initrc_t domain.
224 uucpd_lock_t
228 - Set files with the uucpd_lock_t type, if you want to treat the files
230 as uucpd lock data, stored under the /var/lock directory
231 uucpd_log_t
235 - Set files with the uucpd_log_t type, if you want to treat the data as
237 uucpd log data, usually stored under the /var/log directory.
238 uucpd_ro_t
242 - Set files with the uucpd_ro_t type, if you want to treat the files as
244 uucpd read/only content.
245 uucpd_rw_t
249 - Set files with the uucpd_rw_t type, if you want to treat the files as
251 uucpd read/write content.
252 uucpd_spool_t
256 - Set files with the uucpd_spool_t type, if you want to store the uucpd
258 files under the /var/spool directory.
259 Paths:
262 /var/spool/uucp(/.*)?, /var/spool/uucppublic(/.*)?
263 uucpd_tmp_t
266 - Set files with the uucpd_tmp_t type, if you want to store uucpd tem‐
268 porary files in the /tmp directories.
269 uucpd_var_run_t
273 - Set files with the uucpd_var_run_t type, if you want to store the
275 uucpd files under the /run or /var/run directory.
276 Note: File context can be temporarily modified with the chcon command.
280 If you want to permanently change the file context you need to use the
281 semanage fcontext command. This will modify the SELinux labeling data‐
282 base. You will need to use restorecon to apply the labels.
283
286 semanage fcontext can also be used to manipulate default file context
287 mappings.
288 semanage permissive can also be used to manipulate whether or not a
290 process type is permissive.
291 semanage module can also be used to enable/disable/install/remove pol‐
293 icy modules.
294 semanage port can also be used to manipulate the port definitions
296 semanage boolean can also be used to manipulate the booleans
298 system-config-selinux is a GUI tool available to customize SELinux pol‐
301 icy settings.
