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 open‐
25 shift_initrc_exec_t file type.
26 The default entrypoint paths for the openshift_initrc_t domain are the
28 following:
29 /usr/s?bin/mcollectived, /usr/s?bin/(oo|rhc)-restorer, /usr/s?bin/oo-
31 admin-ctl-gears, /usr/s?bin/(oo|rhc)-restorer-wrapper.sh,
32 /etc/rc.d/init.d/libra, /etc/rc.d/init.d/mcollective
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 openshift_initrc policy is very flexible allowing users to setup their
42 openshift_initrc processes in as secure a method as possible.
43 The following process types are defined for openshift_initrc:
45 openshift_initrc_t
47 Note: semanage permissive -a openshift_initrc_t can be used to make the
49 process type openshift_initrc_t permissive. SELinux does not deny
50 access to permissive process types, but the AVC (SELinux denials) mes‐
51 sages are still generated.
52
55 SELinux policy is customizable based on least access required. open‐
56 shift_initrc policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run openshift_initrc with the
58 tightest access possible.
59 If you want to deny user domains applications to map a memory region as
63 both executable and writable, this is dangerous and the executable
64 should be reported in bugzilla, you must turn on the deny_execmem bool‐
65 ean. Enabled by default.
66 setsebool -P deny_execmem 1
68 If you want to deny any process from ptracing or debugging any other
72 processes, you must turn on the deny_ptrace boolean. Enabled by
73 default.
74 setsebool -P deny_ptrace 1
76 If you want to allow all domains to execute in fips_mode, you must turn
80 on the fips_mode boolean. Enabled by default.
81 setsebool -P fips_mode 1
83 If you want to control the ability to mmap a low area of the address
87 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
88 the mmap_low_allowed boolean. Disabled by default.
89 setsebool -P mmap_low_allowed 1
91 If you want to disable kernel module loading, you must turn on the
95 secure_mode_insmod boolean. Enabled by default.
96 setsebool -P secure_mode_insmod 1
98 If you want to allow unconfined executables to make their heap memory
102 executable. Doing this is a really bad idea. Probably indicates a
103 badly coded executable, but could indicate an attack. This executable
104 should be reported in bugzilla, you must turn on the selin‐
105 uxuser_execheap boolean. Disabled by default.
106 setsebool -P selinuxuser_execheap 1
108 If you want to allow unconfined executables to make their stack exe‐
112 cutable. This should never, ever be necessary. Probably indicates a
113 badly coded executable, but could indicate an attack. This executable
114 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
115 stack boolean. Enabled by default.
116 setsebool -P selinuxuser_execstack 1

122 The SELinux process type openshift_initrc_t can manage files labeled
123 with the following file types. The paths listed are the default paths
124 for these file types. Note the processes UID still need to have DAC
125 permissions.
126 file_type
128 all files on the system
130
133 SELinux requires files to have an extended attribute to define the file
134 type.
135 You can see the context of a file using the -Z option to ls
137 Policy governs the access confined processes have to these files.
139 SELinux openshift_initrc policy is very flexible allowing users to set‐
140 up their openshift_initrc processes in as secure a method as possible.
141 STANDARD FILE CONTEXT
143 SELinux defines the file context types for the openshift_initrc, if you
145 wanted to store files with these types in a diffent paths, you need to
146 execute the semanage command to sepecify alternate labeling and then
147 use restorecon to put the labels on disk.
148 semanage fcontext -a -t openshift_initrc_tmp_t '/srv/myopenshift_ini‐
150 trc_content(/.*)?'
151 restorecon -R -v /srv/myopenshift_initrc_content
152 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155 The following file types are defined for openshift_initrc:
157 openshift_initrc_exec_t
161 - Set files with the openshift_initrc_exec_t type, if you want to tran‐
163 sition an executable to the openshift_initrc_t domain.
164 Paths:
167 /usr/s?bin/mcollectived, /usr/s?bin/(oo|rhc)-restorer,
168 /usr/s?bin/oo-admin-ctl-gears, /usr/s?bin/(oo|rhc)-restorer-wrap‐
169 per.sh, /etc/rc.d/init.d/libra, /etc/rc.d/init.d/mcollective
170 openshift_initrc_tmp_t
173 - Set files with the openshift_initrc_tmp_t type, if you want to store
175 openshift initrc temporary files in the /tmp directories.
176 Note: File context can be temporarily modified with the chcon command.
180 If you want to permanently change the file context you need to use the
181 semanage fcontext command. This will modify the SELinux labeling data‐
182 base. You will need to use restorecon to apply the labels.
183
186 semanage fcontext can also be used to manipulate default file context
187 mappings.
188 semanage permissive can also be used to manipulate whether or not a
190 process type is permissive.
191 semanage module can also be used to enable/disable/install/remove pol‐
193 icy modules.
194 semanage boolean can also be used to manipulate the booleans
196 system-config-selinux is a GUI tool available to customize SELinux pol‐
199 icy settings.
