NAME

6       matahari_hostd_selinux  -  Security Enhanced Linux Policy for the mata‐
7       hari_hostd processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  matahari_hostd_t  SELinux  type  can be entered via the file_type,
25       unlabeled_t,   proc_type,    filesystem_type,    matahari_hostd_exec_t,
26       mtrr_device_t, sysctl_type file types.
27
28       The  default  entrypoint  paths for the matahari_hostd_t domain are the
29       following:
30
31       all files on the system, /usr/sbin/matahari-hostd,  /usr/sbin/matahari-
32       qmf-hostd, /usr/sbin/matahari-dbus-hostd, /dev/cpu/mtrr
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       matahari_hostd  policy  is  very flexible allowing users to setup their
42       matahari_hostd processes in as secure a method as possible.
43
44       The following process types are defined for matahari_hostd:
45
46       matahari_hostd_t
47
48       Note: semanage permissive -a matahari_hostd_t can be used to  make  the
49       process  type matahari_hostd_t permissive. SELinux does not deny access
50       to permissive process types, but the AVC (SELinux denials) messages are
51       still generated.
52
53

BOOLEANS

55       SELinux  policy  is customizable based on least access required.  mata‐
56       hari_hostd policy is extremely flexible and has several  booleans  that
57       allow  you  to  manipulate  the  policy and run matahari_hostd with the
58       tightest access possible.
59
60
61
62       If you want to allow all daemons to write corefiles to /, you must turn
63       on the allow_daemons_dump_core boolean. Disabled by default.
64
65       setsebool -P allow_daemons_dump_core 1
66
67
68
69       If  you want to allow all daemons to use tcp wrappers, you must turn on
70       the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
71
72       setsebool -P allow_daemons_use_tcp_wrapper 1
73
74
75
76       If you want to allow all daemons the ability to  read/write  terminals,
77       you  must  turn  on  the  allow_daemons_use_tty  boolean.  Disabled  by
78       default.
79
80       setsebool -P allow_daemons_use_tty 1
81
82
83
84       If you want to allow all domains to use other domains file descriptors,
85       you must turn on the allow_domain_fd_use boolean. Enabled by default.
86
87       setsebool -P allow_domain_fd_use 1
88
89
90
91       If  you  want to allow unconfined executables to make their heap memory
92       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
93       badly  coded  executable, but could indicate an attack. This executable
94       should be reported in bugzilla, you must  turn  on  the  allow_execheap
95       boolean. Disabled by default.
96
97       setsebool -P allow_execheap 1
98
99
100
101       If  you  want to allow unconfined executables to map a memory region as
102       both executable and writable, this  is  dangerous  and  the  executable
103       should  be  reported  in  bugzilla), you must turn on the allow_execmem
104       boolean. Enabled by default.
105
106       setsebool -P allow_execmem 1
107
108
109
110       If you want to  allow  all  unconfined  executables  to  use  libraries
111       requiring  text  relocation  that are not labeled textrel_shlib_t), you
112       must turn on the allow_execmod boolean. Enabled by default.
113
114       setsebool -P allow_execmod 1
115
116
117
118       If you want to allow unconfined executables to make  their  stack  exe‐
119       cutable.   This  should  never, ever be necessary. Probably indicates a
120       badly coded executable, but could indicate an attack.  This  executable
121       should  be  reported in bugzilla), you must turn on the allow_execstack
122       boolean. Enabled by default.
123
124       setsebool -P allow_execstack 1
125
126
127
128       If you want to allow sysadm to debug or ptrace all processes, you  must
129       turn on the allow_ptrace boolean. Disabled by default.
130
131       setsebool -P allow_ptrace 1
132
133
134
135       If  you  want  to enable cluster mode for daemons, you must turn on the
136       daemons_enable_cluster_mode boolean. Disabled by default.
137
138       setsebool -P daemons_enable_cluster_mode 1
139
140
141
142       If you want to allow all domains to have the kernel load  modules,  you
143       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
144       default.
145
146       setsebool -P domain_kernel_load_modules 1
147
148
149
150       If you want to allow all domains to execute in fips_mode, you must turn
151       on the fips_mode boolean. Enabled by default.
152
153       setsebool -P fips_mode 1
154
155
156
157       If you want to enable reading of urandom for all domains, you must turn
158       on the global_ssp boolean. Disabled by default.
159
160       setsebool -P global_ssp 1
161
162
163
164       If you want to enable support for upstart as the init program, you must

172       you must turn on the mmap_low_allowed boolean. Disabled by default.
173
174       setsebool -P mmap_low_allowed 1
175
176
177
178       If you want to boolean to determine whether the system permits  loading
179       policy,  setting enforcing mode, and changing boolean values.  Set this
180       to true and you have to reboot to set it back, you  must  turn  on  the
181       secure_mode_policyload boolean. Disabled by default.
182
183       setsebool -P secure_mode_policyload 1
184
185
186
187       If you want to support X userspace object manager, you must turn on the
188       xserver_object_manager boolean. Disabled by default.

193

MANAGED FILES

195       The SELinux process type matahari_hostd_t can manage files labeled with
196       the  following  file types.  The paths listed are the default paths for
197       these file types.  Note the processes UID still need to have  DAC  per‐
198       missions.
199
200       file_type
201
202            all files on the system
203
204

FILE CONTEXTS

206       SELinux requires files to have an extended attribute to define the file
207       type.
208
209       You can see the context of a file using the -Z option to ls
210
211       Policy governs the access  confined  processes  have  to  these  files.
212       SELinux  matahari_hostd policy is very flexible allowing users to setup
213       their matahari_hostd processes in as secure a method as possible.
214
215       The following file types are defined for matahari_hostd:
216
217
218
219       matahari_hostd_exec_t
220
221       - Set files with the matahari_hostd_exec_t type, if you want to transi‐
222       tion an executable to the matahari_hostd_t domain.
223
224
225       Paths:
226            /usr/sbin/matahari-hostd,            /usr/sbin/matahari-qmf-hostd,
227            /usr/sbin/matahari-dbus-hostd
228
229
230       Note: File context can be temporarily modified with the chcon  command.
231       If  you want to permanently change the file context you need to use the
232       semanage fcontext command.  This will modify the SELinux labeling data‐
233       base.  You will need to use restorecon to apply the labels.
234
235

COMMANDS

237       semanage  fcontext  can also be used to manipulate default file context
238       mappings.
239
240       semanage permissive can also be used to manipulate  whether  or  not  a
241       process type is permissive.
242
243       semanage  module can also be used to enable/disable/install/remove pol‐
244       icy modules.
245
246       semanage boolean can also be used to manipulate the booleans
247
248
249       system-config-selinux is a GUI tool available to customize SELinux pol‐
250       icy settings.
