NAME

6       lldpad_selinux  -  Security  Enhanced  Linux Policy for the lldpad pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  lldpad  processes  via  flexible
11       mandatory access control.
12
13       The  lldpad  processes  execute with the lldpad_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep lldpad_t
20
21
22

ENTRYPOINTS

24       The  lldpad_t  SELinux  type  can  be  entered  via the file_type, lld‐
25       pad_exec_t,  unlabeled_t,  proc_type,  filesystem_type,  mtrr_device_t,
26       sysctl_type file types.
27
28       The default entrypoint paths for the lldpad_t domain are the following:
29
30       all files on the system, /usr/sbin/lldpad, /dev/cpu/mtrr
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       lldpad  policy  is  very  flexible allowing users to setup their lldpad
40       processes in as secure a method as possible.
41
42       The following process types are defined for lldpad:
43
44       lldpad_t
45
46       Note: semanage permissive -a lldpad_t can be used to make  the  process
47       type  lldpad_t  permissive.  SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy is customizable based on least access required.  lldpad
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate the policy and run lldpad with the tightest access possible.

57
58
59       If you want to allow all daemons to write corefiles to /, you must turn
60       on the allow_daemons_dump_core boolean. Disabled by default.
61
62       setsebool -P allow_daemons_dump_core 1
63
64
65
66       If you want to allow all daemons to use tcp wrappers, you must turn  on
67       the allow_daemons_use_tcp_wrapper boolean. Disabled by default.

72
73       If  you  want to allow all daemons the ability to read/write terminals,
74       you  must  turn  on  the  allow_daemons_use_tty  boolean.  Disabled  by
75       default.

85
86
87
88       If you want to allow unconfined executables to make their  heap  memory
89       executable.   Doing  this  is  a  really bad idea. Probably indicates a
90       badly coded executable, but could indicate an attack.  This  executable
91       should  be  reported  in  bugzilla, you must turn on the allow_execheap
92       boolean. Disabled by default.
93
94       setsebool -P allow_execheap 1
95
96
97
98       If you want to allow unconfined executables to map a memory  region  as
99       both  executable  and  writable,  this  is dangerous and the executable
100       should be reported in bugzilla), you must  turn  on  the  allow_execmem
101       boolean. Enabled by default.
102
103       setsebool -P allow_execmem 1

106
107       If  you  want  to  allow  all  unconfined  executables to use libraries
108       requiring text relocation that are not  labeled  textrel_shlib_t),  you
109       must turn on the allow_execmod boolean. Enabled by default.
110
111       setsebool -P allow_execmod 1
112
113
114
115       If  you  want  to allow unconfined executables to make their stack exe‐
116       cutable.  This should never, ever be necessary.  Probably  indicates  a
117       badly  coded  executable, but could indicate an attack. This executable
118       should be reported in bugzilla), you must turn on  the  allow_execstack
119       boolean. Enabled by default.
120
121       setsebool -P allow_execstack 1
122
123

140       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
141       default.
142
143       setsebool -P domain_kernel_load_modules 1
144
145
146
147       If you want to allow all domains to execute in fips_mode, you must turn
148       on the fips_mode boolean. Enabled by default.
149
150       setsebool -P fips_mode 1
151
152

176       policy, setting enforcing mode, and changing boolean values.  Set  this
177       to  true  and  you  have to reboot to set it back, you must turn on the
178       secure_mode_policyload boolean. Disabled by default.
179
180       setsebool -P secure_mode_policyload 1

MANAGED FILES

192       The  SELinux  process  type  lldpad_t can manage files labeled with the
193       following file types.  The paths listed are the default paths for these
194       file types.  Note the processes UID still need to have DAC permissions.
195
196       file_type
197
198            all files on the system
199
200

FILE CONTEXTS

202       SELinux requires files to have an extended attribute to define the file
203       type.
204
205       You can see the context of a file using the -Z option to ls
206
207       Policy governs the access  confined  processes  have  to  these  files.
208       SELinux  lldpad  policy  is very flexible allowing users to setup their
209       lldpad processes in as secure a method as possible.
210
211       STANDARD FILE CONTEXT
212
213       SELinux defines the file context types for the lldpad, if you wanted to
214       store  files  with  these types in a diffent paths, you need to execute
215       the semanage command  to  sepecify  alternate  labeling  and  then  use
216       restorecon to put the labels on disk.
217
218       semanage fcontext -a -t lldpad_var_run_t '/srv/mylldpad_content(/.*)?'
219       restorecon -R -v /srv/mylldpad_content
220
221       Note:  SELinux  often  uses  regular expressions to specify labels that
222       match multiple files.
223
224       The following file types are defined for lldpad:
225
226
227
228       lldpad_exec_t
229
230       - Set files with the lldpad_exec_t type, if you want to  transition  an
231       executable to the lldpad_t domain.
232
233
234
235       lldpad_initrc_exec_t
236
237       -  Set files with the lldpad_initrc_exec_t type, if you want to transi‐
238       tion an executable to the lldpad_initrc_t domain.
239
240
241
242       lldpad_tmpfs_t
243
244       - Set files with the lldpad_tmpfs_t type, if you want to  store  lldpad
245       files on a tmpfs file system.
246
247
248
249       lldpad_var_lib_t
250
251       -  Set  files  with the lldpad_var_lib_t type, if you want to store the
252       lldpad files under the /var/lib directory.
253
254
255
256       lldpad_var_run_t
257
258       - Set files with the lldpad_var_run_t type, if you want  to  store  the
259       lldpad files under the /run or /var/run directory.
260
261
262
263       Note:  File context can be temporarily modified with the chcon command.
264       If you want to permanently change the file context you need to use  the
265       semanage fcontext command.  This will modify the SELinux labeling data‐
266       base.  You will need to use restorecon to apply the labels.
267
268

COMMANDS

270       semanage fcontext can also be used to manipulate default  file  context
271       mappings.
272
273       semanage  permissive  can  also  be used to manipulate whether or not a
274       process type is permissive.
275
276       semanage module can also be used to enable/disable/install/remove  pol‐
277       icy modules.
278
279       semanage boolean can also be used to manipulate the booleans
280
281
282       system-config-selinux is a GUI tool available to customize SELinux pol‐
283       icy settings.
