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 all domains to use other domains file descriptors,
57 you must turn on the allow_domain_fd_use boolean. Enabled by default.
58 setsebool -P allow_domain_fd_use 1
60 If you want to allow confined applications to run with kerberos, you
64 must turn on the allow_kerberos boolean. Enabled by default.
65 setsebool -P allow_kerberos 1
67 If you want to allow sysadm to debug or ptrace all processes, you must
71 turn on the allow_ptrace boolean. Disabled by default.
72 setsebool -P allow_ptrace 1
74 If you want to allow system to run with NIS, you must turn on the
78 allow_ypbind boolean. Disabled by default.
79 setsebool -P allow_ypbind 1
81 If you want to allow all domains to have the kernel load modules, you
85 must turn on the domain_kernel_load_modules boolean. Disabled by
86 default.
87 setsebool -P domain_kernel_load_modules 1
89 If you want to allow all domains to execute in fips_mode, you must turn
93 on the fips_mode boolean. Enabled by default.
94 setsebool -P fips_mode 1
96 If you want to enable reading of urandom for all domains, you must turn
100 on the global_ssp boolean. Disabled by default.
101 setsebool -P global_ssp 1
103 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Enabled by default.
108 setsebool -P nscd_use_shm 1
110
114 SELinux defines port types to represent TCP and UDP ports.
115 You can see the types associated with a port by using the following
117 command:
118 semanage port -l
120 Policy governs the access confined processes have to these ports.
123 SELinux uucpd policy is very flexible allowing users to setup their
124 uucpd processes in as secure a method as possible.
125 The following port types are defined for uucpd:
127 uucpd_port_t
130 Default Defined Ports:
134 tcp 540
135
137 The SELinux process type uucpd_t can manage files labeled with the fol‐
138 lowing file types. The paths listed are the default paths for these
139 file types. Note the processes UID still need to have DAC permissions.
140 initrc_tmp_t

147 /mnt(/[^/]*)?

191 SELinux requires files to have an extended attribute to define the file
192 type.
193 You can see the context of a file using the -Z option to ls
195 Policy governs the access confined processes have to these files.
197 SELinux uucpd policy is very flexible allowing users to setup their
198 uucpd processes in as secure a method as possible.
199 EQUIVALENCE DIRECTORIES
201 uucpd policy stores data with multiple different file context types
204 under the /var/spool/uucp directory. If you would like to store the
205 data in a different directory you can use the semanage command to cre‐
206 ate an equivalence mapping. If you wanted to store this data under the
207 /srv dirctory you would execute the following command:
208 semanage fcontext -a -e /var/spool/uucp /srv/uucp
210 restorecon -R -v /srv/uucp
211 STANDARD FILE CONTEXT
213 SELinux defines the file context types for the uucpd, if you wanted to
215 store files with these types in a diffent paths, you need to execute
216 the semanage command to sepecify alternate labeling and then use
217 restorecon to put the labels on disk.
218 semanage fcontext -a -t uucpd_var_run_t '/srv/myuucpd_content(/.*)?'
220 restorecon -R -v /srv/myuucpd_content
221 Note: SELinux often uses regular expressions to specify labels that
223 match multiple files.
224 The following file types are defined for uucpd:
226 uucpd_exec_t
230 - Set files with the uucpd_exec_t type, if you want to transition an
232 executable to the uucpd_t domain.
233 uucpd_lock_t
237 - Set files with the uucpd_lock_t type, if you want to treat the files
239 as uucpd lock data, stored under the /var/lock directory
240 uucpd_log_t
244 - Set files with the uucpd_log_t type, if you want to treat the data as
246 uucpd log data, usually stored under the /var/log directory.
247 uucpd_ro_t
251 - Set files with the uucpd_ro_t type, if you want to treat the files as
253 uucpd read/only content.
254 uucpd_rw_t
258 - Set files with the uucpd_rw_t type, if you want to treat the files as
260 uucpd read/write content.
261 uucpd_spool_t
265 - Set files with the uucpd_spool_t type, if you want to store the uucpd
267 files under the /var/spool directory.
268 Paths:
271 /var/spool/uucp(/.*)?, /var/spool/uucppublic(/.*)?
272 uucpd_tmp_t
275 - Set files with the uucpd_tmp_t type, if you want to store uucpd tem‐
277 porary files in the /tmp directories.
278 uucpd_var_run_t
282 - Set files with the uucpd_var_run_t type, if you want to store the
284 uucpd files under the /run or /var/run directory.
285 Note: File context can be temporarily modified with the chcon command.
289 If you want to permanently change the file context you need to use the
290 semanage fcontext command. This will modify the SELinux labeling data‐
291 base. You will need to use restorecon to apply the labels.
292
295 semanage fcontext can also be used to manipulate default file context
296 mappings.
297 semanage permissive can also be used to manipulate whether or not a
299 process type is permissive.
300 semanage module can also be used to enable/disable/install/remove pol‐
302 icy modules.
303 semanage port can also be used to manipulate the port definitions
305 semanage boolean can also be used to manipulate the booleans
307 system-config-selinux is a GUI tool available to customize SELinux pol‐
310 icy settings.
