6 openshift_initrc_selinux - Security Enhanced Linux Policy for the open‐
7 shift_initrc processes
8
10 Security-Enhanced Linux secures the openshift_initrc processes via
11 flexible mandatory access control.
12 The openshift_initrc processes execute with the openshift_initrc_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep openshift_initrc_t
20
24 The openshift_initrc_t SELinux type can be entered via the file_type,
25 openshift_initrc_exec_t file types.
26 The default entrypoint paths for the openshift_initrc_t domain are the
28 following:
29 all files on the system, /usr/s?bin/mcollectived,
31 /usr/s?bin/(oo|rhc)-restorer, /usr/s?bin/oo-admin-ctl-gears,
32 /usr/s?bin/(oo|rhc)-restorer-wrapper.sh, /etc/rc.d/init.d/libra,
33 /etc/rc.d/init.d/mcollective
34
36 SELinux defines process types (domains) for each process running on the
37 system
38 You can see the context of a process using the -Z option to ps
40 Policy governs the access confined processes have to files. SELinux
42 openshift_initrc policy is very flexible allowing users to setup their
43 openshift_initrc processes in as secure a method as possible.
44 The following process types are defined for openshift_initrc:
46 openshift_initrc_t
48 Note: semanage permissive -a openshift_initrc_t can be used to make the
50 process type openshift_initrc_t permissive. SELinux does not deny
51 access to permissive process types, but the AVC (SELinux denials) mes‐
52 sages are still generated.
53
56 SELinux policy is customizable based on least access required. open‐
57 shift_initrc policy is extremely flexible and has several booleans that
58 allow you to manipulate the policy and run openshift_initrc with the
59 tightest access possible.
60 If you want to allow all daemons to write corefiles to /, you must turn
64 on the daemons_dump_core boolean. Disabled by default.
65 setsebool -P daemons_dump_core 1
67 If you want to enable cluster mode for daemons, you must turn on the
71 daemons_enable_cluster_mode boolean. Enabled by default.
72 setsebool -P daemons_enable_cluster_mode 1

78 the daemons_use_tcp_wrapper boolean. Disabled by default.
79 setsebool -P daemons_use_tcp_wrapper 1

85 you must turn on the daemons_use_tty boolean. Disabled by default.
86 setsebool -P daemons_use_tty 1
88 If you want to deny user domains applications to map a memory region as
92 both executable and writable, this is dangerous and the executable
93 should be reported in bugzilla, you must turn on the deny_execmem bool‐
94 ean. Enabled by default.
95 setsebool -P deny_execmem 1
97 If you want to deny any process from ptracing or debugging any other
101 processes, you must turn on the deny_ptrace boolean. Enabled by
102 default.
103 setsebool -P deny_ptrace 1
105 If you want to allow any process to mmap any file on system with
109 attribute file_type, you must turn on the domain_can_mmap_files bool‐
110 ean. Enabled by default.
111 setsebool -P domain_can_mmap_files 1
113 If you want to allow all domains write to kmsg_device, while kernel is
117 executed with systemd.log_target=kmsg parameter, you must turn on the
118 domain_can_write_kmsg boolean. Disabled by default.

147 on the global_ssp boolean. Disabled by default.
148 setsebool -P global_ssp 1
150 If you want to control the ability to mmap a low area of the address
154 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
155 the mmap_low_allowed boolean. Disabled by default.
156 setsebool -P mmap_low_allowed 1
158 If you want to disable kernel module loading, you must turn on the
162 secure_mode_insmod boolean. Enabled by default.
163 setsebool -P secure_mode_insmod 1
165 If you want to boolean to determine whether the system permits loading
169 policy, setting enforcing mode, and changing boolean values. Set this

171 secure_mode_policyload boolean. Enabled by default.
172 setsebool -P secure_mode_policyload 1
174 If you want to allow unconfined executables to make their heap memory
178 executable. Doing this is a really bad idea. Probably indicates a
179 badly coded executable, but could indicate an attack. This executable
180 should be reported in bugzilla, you must turn on the selin‐
181 uxuser_execheap boolean. Disabled by default.
182 setsebool -P selinuxuser_execheap 1

192 If you want to allow unconfined executables to make their stack exe‐
196 cutable. This should never, ever be necessary. Probably indicates a

199 stack boolean. Enabled by default.

223 If you want to support X userspace object manager, you must turn on the
227 xserver_object_manager boolean. Enabled by default.
228 setsebool -P xserver_object_manager 1
230
234 The SELinux process type openshift_initrc_t can manage files labeled
235 with the following file types. The paths listed are the default paths
236 for these file types. Note the processes UID still need to have DAC
237 permissions.
238 file_type
240 all files on the system
242
245 SELinux requires files to have an extended attribute to define the file
246 type.
247 You can see the context of a file using the -Z option to ls
249 Policy governs the access confined processes have to these files.
251 SELinux openshift_initrc policy is very flexible allowing users to set‐
252 up their openshift_initrc processes in as secure a method as possible.
253 STANDARD FILE CONTEXT
255 SELinux defines the file context types for the openshift_initrc, if you
257 wanted to store files with these types in a diffent paths, you need to
258 execute the semanage command to sepecify alternate labeling and then
259 use restorecon to put the labels on disk.
260 semanage fcontext -a -t openshift_initrc_tmp_t '/srv/myopenshift_ini‐
262 trc_content(/.*)?'
263 restorecon -R -v /srv/myopenshift_initrc_content
264 Note: SELinux often uses regular expressions to specify labels that
266 match multiple files.
267 The following file types are defined for openshift_initrc:
269 openshift_initrc_exec_t
273 - Set files with the openshift_initrc_exec_t type, if you want to tran‐
275 sition an executable to the openshift_initrc_t domain.
276 Paths:
279 /usr/s?bin/mcollectived, /usr/s?bin/(oo|rhc)-restorer,
280 /usr/s?bin/oo-admin-ctl-gears, /usr/s?bin/(oo|rhc)-restorer-wrap‐
281 per.sh, /etc/rc.d/init.d/libra, /etc/rc.d/init.d/mcollective
282 openshift_initrc_tmp_t
285 - Set files with the openshift_initrc_tmp_t type, if you want to store
287 openshift initrc temporary files in the /tmp directories.
288 Note: File context can be temporarily modified with the chcon command.
292 If you want to permanently change the file context you need to use the
293 semanage fcontext command. This will modify the SELinux labeling data‐
294 base. You will need to use restorecon to apply the labels.
295
298 semanage fcontext can also be used to manipulate default file context
299 mappings.
300 semanage permissive can also be used to manipulate whether or not a
302 process type is permissive.
303 semanage module can also be used to enable/disable/install/remove pol‐
305 icy modules.
306 semanage boolean can also be used to manipulate the booleans
308 system-config-selinux is a GUI tool available to customize SELinux pol‐
311 icy settings.
