NAME

6       rtas_errd_selinux  -  Security  Enhanced Linux Policy for the rtas_errd
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  rtas_errd_t  SELinux  type can be entered via the rtas_errd_exec_t
25       file type.
26
27       The default entrypoint paths for the rtas_errd_t domain are the follow‐
28       ing:
29
30       /usr/sbin/rtas_errd, /usr/libexec/ppc64-diag/rtas_errd
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       rtas_errd  policy  is  very  flexible  allowing  users  to  setup their
40       rtas_errd processes in as secure a method as possible.
41
42       The following process types are defined for rtas_errd:
43
44       rtas_errd_t
45
46       Note: semanage permissive -a  rtas_errd_t  can  be  used  to  make  the
47       process  type  rtas_errd_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       rtas_errd policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run rtas_errd with the tightest
56       access possible.
57
58
59
60       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
61       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
62       Enabled by default.
63
64       setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68       If you want to deny user domains applications to map a memory region as
69       both  executable  and  writable,  this  is dangerous and the executable
70       should be reported in bugzilla, you must turn on the deny_execmem bool‐
71       ean. Disabled by default.
72
73       setsebool -P deny_execmem 1
74
75
76
77       If  you  want  to control the ability to mmap a low area of the address
78       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
79       the mmap_low_allowed boolean. Disabled by default.
80
81       setsebool -P mmap_low_allowed 1
82
83
84
85       If  you  want  to  allow  system  to run with NIS, you must turn on the
86       nis_enabled boolean. Disabled by default.
87
88       setsebool -P nis_enabled 1
89
90
91
92       If you want to disable kernel module loading, you must turn on the  se‐
93       cure_mode_insmod boolean. Disabled by default.
94
95       setsebool -P secure_mode_insmod 1
96
97
98
99       If  you  want to allow unconfined executables to make their heap memory
100       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
101       badly  coded  executable, but could indicate an attack. This executable
102       should be reported in bugzilla, you must turn  on  the  selinuxuser_ex‐
103       echeap boolean. Disabled by default.
104
105       setsebool -P selinuxuser_execheap 1
106
107
108
109       If  you  want  to allow unconfined executables to make their stack exe‐
110       cutable.  This should never, ever be necessary.  Probably  indicates  a
111       badly  coded  executable, but could indicate an attack. This executable
112       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
113       stack boolean. Enabled by default.
114
115       setsebool -P selinuxuser_execstack 1

MANAGED FILES

120       The  SELinux process type rtas_errd_t can manage files labeled with the
121       following file types.  The paths listed are the default paths for these
122       file types.  Note the processes UID still need to have DAC permissions.
123
124       file_type
125
126            all files on the system
127
128

FILE CONTEXTS

130       SELinux requires files to have an extended attribute to define the file
131       type.
132
133       You can see the context of a file using the -Z option to ls
134
135       Policy governs the access  confined  processes  have  to  these  files.
136       SELinux rtas_errd policy is very flexible allowing users to setup their
137       rtas_errd processes in as secure a method as possible.
138
139       STANDARD FILE CONTEXT
140
141       SELinux defines the file context types for the rtas_errd, if you wanted
142       to  store files with these types in a different paths, you need to exe‐
143       cute the semanage command to specify alternate labeling  and  then  use
144       restorecon to put the labels on disk.
145
146       semanage fcontext -a -t rtas_errd_exec_t '/srv/rtas_errd/content(/.*)?'
147       restorecon -R -v /srv/myrtas_errd_content
148
149       Note:  SELinux  often  uses  regular expressions to specify labels that
150       match multiple files.
151
152       The following file types are defined for rtas_errd:
153
154
155
156       rtas_errd_exec_t
157
158       - Set files with the rtas_errd_exec_t type, if you want  to  transition
159       an executable to the rtas_errd_t domain.
160
161
162       Paths:
163            /usr/sbin/rtas_errd, /usr/libexec/ppc64-diag/rtas_errd
164
165
166       rtas_errd_log_t
167
168       -  Set  files  with  the rtas_errd_log_t type, if you want to treat the
169       data as rtas errd log data, usually stored under  the  /var/log  direc‐
170       tory.
171
172
173       Paths:
174            /var/log/platform.*, /var/log/rtas_errd.*, /var/log/epow_status.*
175
176
177       rtas_errd_tmp_t
178
179       -  Set  files  with the rtas_errd_tmp_t type, if you want to store rtas
180       errd temporary files in the /tmp directories.
181
182
183
184       rtas_errd_tmpfs_t
185
186       - Set files with the rtas_errd_tmpfs_t type, if you want to store  rtas
187       errd files on a tmpfs file system.
188
189
190
191       rtas_errd_unit_file_t
192
193       -  Set  files with the rtas_errd_unit_file_t type, if you want to treat
194       the files as rtas errd unit content.
195
196
197
198       rtas_errd_var_lock_t
199
200       - Set files with the rtas_errd_var_lock_t type, if you  want  to  treat
201       the files as rtas errd var lock data, stored under the /var/lock direc‐
202       tory
203
204
205       Paths:
206            /var/lock/.*librtas, /var/lock/subsys/rtas_errd
207
208
209       rtas_errd_var_run_t
210
211       - Set files with the rtas_errd_var_run_t type, if you want to store the
212       rtas errd files under the /run or /var/run directory.
213
214
215
216       Note:  File context can be temporarily modified with the chcon command.
217       If you want to permanently change the file context you need to use  the
218       semanage fcontext command.  This will modify the SELinux labeling data‐
219       base.  You will need to use restorecon to apply the labels.
220
221

COMMANDS

223       semanage fcontext can also be used to manipulate default  file  context
224       mappings.
225
226       semanage  permissive  can  also  be used to manipulate whether or not a
227       process type is permissive.
228
229       semanage module can also be used to enable/disable/install/remove  pol‐
230       icy modules.
231
232       semanage boolean can also be used to manipulate the booleans
233
234
235       system-config-selinux is a GUI tool available to customize SELinux pol‐
236       icy settings.
