NAME

6       openshift_selinux  -  Security  Enhanced Linux Policy for the openshift
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the openshift  processes  via  flexible
11       mandatory access control.
12
13       The  openshift processes execute with the openshift_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 openshift_t
20
21
22

ENTRYPOINTS

24       The  openshift_t  SELinux  type  can be entered via the crontab_exec_t,
25       user_cron_spool_t file types.
26
27       The default entrypoint paths for the openshift_t domain are the follow‐
28       ing:
29
30       /usr/bin/(f)?crontab,        /usr/bin/at,        /usr/sbin/fcronsighup,
31       /usr/libexec/fcronsighup,     /var/spool/at(/.*)?,     /var/spool/cron,
32       /var/spool/cron/[^/]+
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       openshift  policy  is very flexible allowing users to setup their open‐
42       shift processes in as secure a method as possible.
43
44       The following process types are defined for openshift:
45
46       openshift_initrc_t, openshift_cgroup_read_t, openshift_net_read_t, openshift_cron_t, openshift_t, openshift_app_t, openshift_script_t
47
48       Note: semanage permissive -a  openshift_t  can  be  used  to  make  the
49       process  type  openshift_t  permissive. SELinux does not deny access to
50       permissive process types, but the AVC (SELinux  denials)  messages  are
51       still generated.
52
53

MCS Constrained

55       The  SELinux  process  type openshift_t is an MCS (Multi Category Secu‐
56       rity) constrained type.  Sometimes this separation is  referred  to  as
57       sVirt.  These types are usually used for securing multi-tenant environ‐
58       ments, such as virtualization, containers or separation of users.   The
59       tools used to launch MCS types, pick out a different MCS label for each
60       process group.
61
62       For example one process might be  launched  with  openshift_t:s0:c1,c2,
63       and  another  process  launched  with openshift_t:s0:c3,c4. The SELinux
64       kernel only allows these processes can only write  to  content  with  a
65       matching  MCS  label,  or a MCS Label of s0. A process running with the
66       MCS level of s0:c1,c2 is not allowed to write to content with  the  MCS
67       label of s0:c3,c4
68
69

BOOLEANS

71       SELinux  policy  is customizable based on least access required.  open‐
72       shift policy is extremely flexible and has several booleans that  allow
73       you to manipulate the policy and run openshift with the tightest access
74       possible.
75
76
77
78       If you want to determine whether crond can execute  jobs  in  the  user
79       domain  as  opposed to the the generic cronjob domain, you must turn on
80       the cron_userdomain_transition boolean. Enabled by default.
81
82       setsebool -P cron_userdomain_transition 1
83
84
85
86       If you want to deny any process from ptracing or  debugging  any  other
87       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
88       default.
89
90       setsebool -P deny_ptrace 1
91
92
93

PORT TYPES

95       SELinux defines port types to represent TCP and UDP ports.
96
97       You can see the types associated with a port  by  using  the  following
98       command:
99
100       semanage port -l
101
102
103       Policy  governs  the  access  confined  processes  have to these ports.
104       SELinux openshift policy is very flexible allowing users to setup their
105       openshift processes in as secure a method as possible.
106
107       The following port types are defined for openshift:
108
109
110       openshift_port_t
111
112
113
114       MANAGED FILES
115
116              The  SELinux  process  type openshift_t can manage files labeled
117              with the following file types.  The paths listed are the default
118              paths  for  these file types.  Note the processes UID still need
119              to have DAC permissions.

FILE CONTEXTS

168       SELinux requires files to have an extended attribute to define the file
169       type.
170
171       You can see the context of a file using the -Z option to ls
172
173       Policy  governs  the  access  confined  processes  have to these files.
174       SELinux openshift policy is very flexible allowing users to setup their
175       openshift processes in as secure a method as possible.
176
177       EQUIVALENCE DIRECTORIES
178
179
180       openshift policy stores data with multiple different file context types
181       under the /var/lib/openshift directory.  If you would like to store the
182       data  in a different directory you can use the semanage command to cre‐
183       ate an equivalence mapping.  If you wanted to store this data under the
184       /srv directory you would execute the following command:
185
186       semanage fcontext -a -e /var/lib/openshift /srv/openshift
187       restorecon -R -v /srv/openshift
188
189       openshift policy stores data with multiple different file context types
190       under the /var/lib/stickshift directory.  If you would  like  to  store
191       the  data  in a different directory you can use the semanage command to
192       create an equivalence mapping.  If you wanted to store this data  under
193       the /srv directory you would execute the following command:
194
195       semanage fcontext -a -e /var/lib/stickshift /srv/stickshift
196       restorecon -R -v /srv/stickshift
197
198       STANDARD FILE CONTEXT
199
200       SELinux defines the file context types for the openshift, if you wanted
201       to store files with these types in a diffent paths, you need to execute
202       the  semanage  command  to  sepecify  alternate  labeling  and then use
203       restorecon to put the labels on disk.
204
205       semanage fcontext -a -t  openshift_ra_content_t  '/srv/myopenshift_con‐
206       tent(/.*)?'
207       restorecon -R -v /srv/myopenshift_content
208
209       Note:  SELinux  often  uses  regular expressions to specify labels that
210       match multiple files.

375       If  you want to permanently change the file context you need to use the
376       semanage fcontext command.  This will modify the SELinux labeling data‐
377       base.  You will need to use restorecon to apply the labels.
378
379

COMMANDS

381       semanage  fcontext  can also be used to manipulate default file context
382       mappings.
383
384       semanage permissive can also be used to manipulate  whether  or  not  a
385       process type is permissive.
386
387       semanage  module can also be used to enable/disable/install/remove pol‐
388       icy modules.
389
390       semanage port can also be used to manipulate the port definitions
391
392       semanage boolean can also be used to manipulate the booleans
393
394
395       system-config-selinux is a GUI tool available to customize SELinux pol‐
396       icy settings.
