6 openwsman_selinux - Security Enhanced Linux Policy for the openwsman
7 processes
8
10 Security-Enhanced Linux secures the openwsman processes via flexible
11 mandatory access control.
12 The openwsman processes execute with the openwsman_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 For example:
18 ps -eZ | grep openwsman_t
20
24 The openwsman_t SELinux type can be entered via the file_type, unla‐
25 beled_t, proc_type, filesystem_type, openwsman_exec_t, mtrr_device_t,
26 sysctl_type file types.
27 The default entrypoint paths for the openwsman_t domain are the follow‐
29 ing:
30 all files on the system, /usr/sbin/openwsmand, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 openwsman policy is very flexible allowing users to setup their openws‐
41 man processes in as secure a method as possible.
42 The following process types are defined for openwsman:
44 openwsman_t
46 Note: semanage permissive -a openwsman_t can be used to make the
48 process type openwsman_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. openws‐
55 man policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run openwsman with the tightest access
57 possible.
58 If you want to allow all daemons to write corefiles to /, you must turn
62 on the allow_daemons_dump_core boolean. Disabled by default.
63 setsebool -P allow_daemons_dump_core 1
65 If you want to allow all daemons to use tcp wrappers, you must turn on

85 setsebool -P allow_domain_fd_use 1
87 If you want to allow unconfined executables to make their heap memory
91 executable. Doing this is a really bad idea. Probably indicates a
92 badly coded executable, but could indicate an attack. This executable
93 should be reported in bugzilla, you must turn on the allow_execheap
94 boolean. Disabled by default.
95 setsebool -P allow_execheap 1
97 If you want to allow unconfined executables to map a memory region as
101 both executable and writable, this is dangerous and the executable
102 should be reported in bugzilla), you must turn on the allow_execmem
103 boolean. Enabled by default.
104 setsebool -P allow_execmem 1
106 If you want to allow all unconfined executables to use libraries
110 requiring text relocation that are not labeled textrel_shlib_t), you
111 must turn on the allow_execmod boolean. Enabled by default.
112 setsebool -P allow_execmod 1
114 If you want to allow unconfined executables to make their stack exe‐
118 cutable. This should never, ever be necessary. Probably indicates a
119 badly coded executable, but could indicate an attack. This executable
120 should be reported in bugzilla), you must turn on the allow_execstack
121 boolean. Enabled by default.
122 setsebool -P allow_execstack 1
124 If you want to allow confined applications to run with kerberos, you
128 must turn on the allow_kerberos boolean. Enabled by default.
129 setsebool -P allow_kerberos 1

149 daemons_enable_cluster_mode boolean. Disabled by default.
150 setsebool -P daemons_enable_cluster_mode 1
152 If you want to allow all domains to have the kernel load modules, you
156 must turn on the domain_kernel_load_modules boolean. Disabled by
157 default.
158 setsebool -P domain_kernel_load_modules 1
160 If you want to allow all domains to execute in fips_mode, you must turn
164 on the fips_mode boolean. Enabled by default.
165 setsebool -P fips_mode 1
167 If you want to enable reading of urandom for all domains, you must turn
171 on the global_ssp boolean. Disabled by default.
172 setsebool -P global_ssp 1
174 If you want to enable support for upstart as the init program, you must
178 turn on the init_upstart boolean. Enabled by default.
179 setsebool -P init_upstart 1
181 If you want to allow certain domains to map low memory in the kernel,
185 you must turn on the mmap_low_allowed boolean. Disabled by default.
186 setsebool -P mmap_low_allowed 1
188 If you want to allow confined applications to use nscd shared memory,
192 you must turn on the nscd_use_shm boolean. Enabled by default.
193 setsebool -P nscd_use_shm 1
195 If you want to boolean to determine whether the system permits loading
199 policy, setting enforcing mode, and changing boolean values. Set this
200 to true and you have to reboot to set it back, you must turn on the
201 secure_mode_policyload boolean. Disabled by default.
202 setsebool -P secure_mode_policyload 1
204 If you want to support X userspace object manager, you must turn on the
208 xserver_object_manager boolean. Disabled by default.
209 setsebool -P xserver_object_manager 1

215 The SELinux process type openwsman_t can manage files labeled with the
216 following file types. The paths listed are the default paths for these
217 file types. Note the processes UID still need to have DAC permissions.
218 file_type
220 all files on the system
222
225 SELinux requires files to have an extended attribute to define the file
226 type.
227 You can see the context of a file using the -Z option to ls
229 Policy governs the access confined processes have to these files.
231 SELinux openwsman policy is very flexible allowing users to setup their
232 openwsman processes in as secure a method as possible.
233 STANDARD FILE CONTEXT
235 SELinux defines the file context types for the openwsman, if you wanted
237 to store files with these types in a diffent paths, you need to execute
238 the semanage command to sepecify alternate labeling and then use
239 restorecon to put the labels on disk.
240 semanage fcontext -a -t openwsman_tmpfs_t '/srv/myopenwsman_con‐
242 tent(/.*)?'
243 restorecon -R -v /srv/myopenwsman_content
244 Note: SELinux often uses regular expressions to specify labels that
246 match multiple files.
247 The following file types are defined for openwsman:
249 openwsman_exec_t
253 - Set files with the openwsman_exec_t type, if you want to transition
255 an executable to the openwsman_t domain.
256 openwsman_initrc_exec_t
260 - Set files with the openwsman_initrc_exec_t type, if you want to tran‐
262 sition an executable to the openwsman_initrc_t domain.
263 openwsman_log_t
267 - Set files with the openwsman_log_t type, if you want to treat the
269 data as openwsman log data, usually stored under the /var/log direc‐
270 tory.
271 openwsman_run_t
275 - Set files with the openwsman_run_t type, if you want to treat the
277 files as openwsman run data.
278 openwsman_tmp_t
282 - Set files with the openwsman_tmp_t type, if you want to store openws‐
284 man temporary files in the /tmp directories.
285 openwsman_tmpfs_t
289 - Set files with the openwsman_tmpfs_t type, if you want to store open‐
291 wsman files on a tmpfs file system.
292 Note: File context can be temporarily modified with the chcon command.
296 If you want to permanently change the file context you need to use the
297 semanage fcontext command. This will modify the SELinux labeling data‐
298 base. You will need to use restorecon to apply the labels.
299
302 semanage fcontext can also be used to manipulate default file context
303 mappings.
304 semanage permissive can also be used to manipulate whether or not a
306 process type is permissive.
307 semanage module can also be used to enable/disable/install/remove pol‐
309 icy modules.
310 semanage boolean can also be used to manipulate the booleans
312 system-config-selinux is a GUI tool available to customize SELinux pol‐
315 icy settings.
