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 SELinux defines process types (domains) for each process running on the
25 system
26 You can see the context of a process using the -Z option to ps
28 Policy governs the access confined processes have to files. SELinux
30 openshift_initrc policy is very flexible allowing users to setup their
31 openshift_initrc processes in as secure a method as possible.
32 The following process types are defined for openshift_initrc:
34 openshift_initrc_t
36 Note: semanage permissive -a openshift_initrc_t can be used to make the
38 process type openshift_initrc_t permissive. SELinux does not deny ac‐
39 cess to permissive process types, but the AVC (SELinux denials) mes‐
40 sages are still generated.
41
44 SELinux policy is customizable based on least access required. open‐
45 shift_initrc policy is extremely flexible and has several booleans that
46 allow you to manipulate the policy and run openshift_initrc with the
47 tightest access possible.
48 If you want to dontaudit all daemons scheduling requests (setsched,
52 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
53 Enabled by default.
54 setsebool -P daemons_dontaudit_scheduling 1
56 If you want to deny user domains applications to map a memory region as
60 both executable and writable, this is dangerous and the executable
61 should be reported in bugzilla, you must turn on the deny_execmem bool‐
62 ean. Disabled by default.
63 setsebool -P deny_execmem 1
65 If you want to control the ability to mmap a low area of the address
69 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
70 the mmap_low_allowed boolean. Disabled by default.
71 setsebool -P mmap_low_allowed 1
73 If you want to disable kernel module loading, you must turn on the se‐
77 cure_mode_insmod boolean. Disabled by default.
78 setsebool -P secure_mode_insmod 1
80 If you want to allow unconfined executables to make their heap memory
84 executable. Doing this is a really bad idea. Probably indicates a
85 badly coded executable, but could indicate an attack. This executable
86 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
87 echeap boolean. Disabled by default.
88 setsebool -P selinuxuser_execheap 1
90 If you want to allow unconfined executables to make their stack exe‐
94 cutable. This should never, ever be necessary. Probably indicates a
95 badly coded executable, but could indicate an attack. This executable
96 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
97 stack boolean. Enabled by default.
98 setsebool -P selinuxuser_execstack 1

104 The SELinux process type openshift_initrc_t can manage files labeled
105 with the following file types. The paths listed are the default paths
106 for these file types. Note the processes UID still need to have DAC
107 permissions.
108 file_type
110 all files on the system
112
115 SELinux requires files to have an extended attribute to define the file
116 type.
117 You can see the context of a file using the -Z option to ls
119 Policy governs the access confined processes have to these files.
121 SELinux openshift_initrc policy is very flexible allowing users to
122 setup their openshift_initrc processes in as secure a method as possi‐
123 ble.
124 STANDARD FILE CONTEXT
126 SELinux defines the file context types for the openshift_initrc, if you
128 wanted to store files with these types in a different paths, you need
129 to execute the semanage command to specify alternate labeling and then
130 use restorecon to put the labels on disk.
131 semanage fcontext -a -t openshift_initrc_exec_t '/srv/openshift_ini‐
133 trc/content(/.*)?'
134 restorecon -R -v /srv/myopenshift_initrc_content
135 Note: SELinux often uses regular expressions to specify labels that
137 match multiple files.
138 The following file types are defined for openshift_initrc:
140 openshift_initrc_exec_t
144 - Set files with the openshift_initrc_exec_t type, if you want to tran‐
146 sition an executable to the openshift_initrc_t domain.
147 Paths:
150 /usr/s?bin/mcollectived, /usr/s?bin/(oo|rhc)-restorer,
151 /usr/s?bin/oo-admin-ctl-gears, /usr/s?bin/(oo|rhc)-restorer-wrap‐
152 per.sh, /etc/rc.d/init.d/libra, /etc/rc.d/init.d/mcollective
153 openshift_initrc_tmp_t
156 - Set files with the openshift_initrc_tmp_t type, if you want to store
158 openshift initrc temporary files in the /tmp directories.
159 Note: File context can be temporarily modified with the chcon command.
163 If you want to permanently change the file context you need to use the
164 semanage fcontext command. This will modify the SELinux labeling data‐
165 base. You will need to use restorecon to apply the labels.
166
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177 semanage boolean can also be used to manipulate the booleans
179 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
