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 deny user domains applications to map a memory region as
52 both executable and writable, this is dangerous and the executable
53 should be reported in bugzilla, you must turn on the deny_execmem bool‐
54 ean. Enabled by default.
55 setsebool -P deny_execmem 1
57 If you want to control the ability to mmap a low area of the address
61 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
62 the mmap_low_allowed boolean. Disabled by default.
63 setsebool -P mmap_low_allowed 1
65 If you want to disable kernel module loading, you must turn on the se‐
69 cure_mode_insmod boolean. Enabled by default.
70 setsebool -P secure_mode_insmod 1
72 If you want to allow unconfined executables to make their heap memory
76 executable. Doing this is a really bad idea. Probably indicates a
77 badly coded executable, but could indicate an attack. This executable
78 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
79 echeap boolean. Disabled by default.
80 setsebool -P selinuxuser_execheap 1
82 If you want to allow unconfined executables to make their stack exe‐
86 cutable. This should never, ever be necessary. Probably indicates a
87 badly coded executable, but could indicate an attack. This executable
88 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
89 stack boolean. Enabled by default.
90 setsebool -P selinuxuser_execstack 1

96 The SELinux process type openshift_initrc_t can manage files labeled
97 with the following file types. The paths listed are the default paths
98 for these file types. Note the processes UID still need to have DAC
99 permissions.
100 file_type
102 all files on the system
104
107 SELinux requires files to have an extended attribute to define the file
108 type.
109 You can see the context of a file using the -Z option to ls
111 Policy governs the access confined processes have to these files.
113 SELinux openshift_initrc policy is very flexible allowing users to
114 setup their openshift_initrc processes in as secure a method as possi‐
115 ble.
116 STANDARD FILE CONTEXT
118 SELinux defines the file context types for the openshift_initrc, if you
120 wanted to store files with these types in a diffent paths, you need to
121 execute the semanage command to sepecify alternate labeling and then
122 use restorecon to put the labels on disk.
123 semanage fcontext -a -t openshift_initrc_tmp_t '/srv/myopenshift_ini‐
125 trc_content(/.*)?'
126 restorecon -R -v /srv/myopenshift_initrc_content
127 Note: SELinux often uses regular expressions to specify labels that
129 match multiple files.
130 The following file types are defined for openshift_initrc:
132 openshift_initrc_exec_t
136 - Set files with the openshift_initrc_exec_t type, if you want to tran‐
138 sition an executable to the openshift_initrc_t domain.
139 Paths:
142 /usr/s?bin/mcollectived, /usr/s?bin/(oo|rhc)-restorer,
143 /usr/s?bin/oo-admin-ctl-gears, /usr/s?bin/(oo|rhc)-restorer-wrap‐
144 per.sh, /etc/rc.d/init.d/libra, /etc/rc.d/init.d/mcollective
145 openshift_initrc_tmp_t
148 - Set files with the openshift_initrc_tmp_t type, if you want to store
150 openshift initrc temporary files in the /tmp directories.
151 Note: File context can be temporarily modified with the chcon command.
155 If you want to permanently change the file context you need to use the
156 semanage fcontext command. This will modify the SELinux labeling data‐
157 base. You will need to use restorecon to apply the labels.
158
161 semanage fcontext can also be used to manipulate default file context
162 mappings.
163 semanage permissive can also be used to manipulate whether or not a
165 process type is permissive.
166 semanage module can also be used to enable/disable/install/remove pol‐
168 icy modules.
169 semanage boolean can also be used to manipulate the booleans
171 system-config-selinux is a GUI tool available to customize SELinux pol‐
174 icy settings.
