6 openshift_app_selinux - Security Enhanced Linux Policy for the open‐
7 shift_app processes
8
10 Security-Enhanced Linux secures the openshift_app processes via flexi‐
11 ble mandatory access control.
12 The openshift_app processes execute with the openshift_app_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep openshift_app_t
20
24 The openshift_app_t SELinux type can be entered via the shell_exec_t,
25 bin_t, openshift_file_type, usr_t, gpg_exec_t, httpd_exec_t,
26 user_cron_spool_t file types.
27 The default entrypoint paths for the openshift_app_t domain are the
29 following:
30 All executeables with the default executable label, usually stored in
32 /usr/bin and /usr/sbin. /bin/d?ash, /bin/zsh.*, /bin/ksh.*,
33 /usr/bin/d?ash, /usr/bin/ksh.*, /usr/bin/zsh.*, /bin/esh, /bin/mksh,

52 SELinux defines process types (domains) for each process running on the
53 system
54 You can see the context of a process using the -Z option to ps
56 Policy governs the access confined processes have to files. SELinux
58 openshift_app policy is very flexible allowing users to setup their
59 openshift_app processes in as secure a method as possible.
60 The following process types are defined for openshift_app:
62 openshift_app_t
64 Note: semanage permissive -a openshift_app_t can be used to make the
66 process type openshift_app_t permissive. SELinux does not deny access
67 to permissive process types, but the AVC (SELinux denials) messages are
68 still generated.
69
72 The SELinux process type openshift_app_t is an MCS (Multi Category
73 Security) constrained type. Sometimes this separation is referred to
74 as sVirt. These types are usually used for securing multi-tenant envi‐
75 ronments, such as virtualization, containers or separation of users.
76 The tools used to launch MCS types, pick out a different MCS label for
77 each process group.
78 For example one process might be launched with open‐
80 shift_app_t:s0:c1,c2, and another process launched with open‐
81 shift_app_t:s0:c3,c4. The SELinux kernel only allows these processes
82 can only write to content with a matching MCS label, or a MCS Label of
83 s0. A process running with the MCS level of s0:c1,c2 is not allowed to
84 write to content with the MCS label of s0:c3,c4
85
88 SELinux policy is customizable based on least access required. open‐
89 shift_app policy is extremely flexible and has several booleans that
90 allow you to manipulate the policy and run openshift_app with the
91 tightest access possible.
92 If you want to allow users to resolve user passwd entries directly from
96 ldap rather then using a sssd server, you must turn on the authlo‐
97 gin_nsswitch_use_ldap boolean. Disabled by default.
98 setsebool -P authlogin_nsswitch_use_ldap 1
100 If you want to determine whether crond can execute jobs in the user
104 domain as opposed to the the generic cronjob domain, you must turn on
105 the cron_userdomain_transition boolean. Enabled by default.
106 setsebool -P cron_userdomain_transition 1
108 If you want to deny any process from ptracing or debugging any other
112 processes, you must turn on the deny_ptrace boolean. Enabled by
113 default.
114 setsebool -P deny_ptrace 1
116 If you want to allow any process to mmap any file on system with
120 attribute file_type, you must turn on the domain_can_mmap_files bool‐
121 ean. Enabled by default.
122 setsebool -P domain_can_mmap_files 1
124 If you want to allow all domains write to kmsg_device, while kernel is
128 executed with systemd.log_target=kmsg parameter, you must turn on the
129 domain_can_write_kmsg boolean. Disabled by default.
130 setsebool -P domain_can_write_kmsg 1
132 If you want to allow all domains to use other domains file descriptors,
136 you must turn on the domain_fd_use boolean. Enabled by default.
137 setsebool -P domain_fd_use 1
139 If you want to allow all domains to have the kernel load modules, you
143 must turn on the domain_kernel_load_modules boolean. Disabled by
144 default.
145 setsebool -P domain_kernel_load_modules 1
147 If you want to allow all domains to execute in fips_mode, you must turn
151 on the fips_mode boolean. Enabled by default.
152 setsebool -P fips_mode 1
154 If you want to enable reading of urandom for all domains, you must turn
158 on the global_ssp boolean. Disabled by default.
159 setsebool -P global_ssp 1
161 If you want to allow confined applications to run with kerberos, you
165 must turn on the kerberos_enabled boolean. Enabled by default.
166 setsebool -P kerberos_enabled 1
168 If you want to allow system to run with NIS, you must turn on the
172 nis_enabled boolean. Disabled by default.
173 setsebool -P nis_enabled 1
175 If you want to allow confined applications to use nscd shared memory,
179 you must turn on the nscd_use_shm boolean. Disabled by default.
180 setsebool -P nscd_use_shm 1
182 If you want to allow openshift to access nfs file systems without
186 labels, you must turn on the openshift_use_nfs boolean. Disabled by
187 default.
188 setsebool -P openshift_use_nfs 1
190
194 The SELinux process type openshift_app_t can manage files labeled with
195 the following file types. The paths listed are the default paths for
196 these file types. Note the processes UID still need to have DAC per‐
197 missions.

231 semanage fcontext can also be used to manipulate default file context
232 mappings.
233 semanage permissive can also be used to manipulate whether or not a
235 process type is permissive.
236 semanage module can also be used to enable/disable/install/remove pol‐
238 icy modules.
239 semanage boolean can also be used to manipulate the booleans
241 system-config-selinux is a GUI tool available to customize SELinux pol‐
244 icy settings.
