6 pegasus_openlmi_unconfined_selinux - Security Enhanced Linux Policy for
7 the pegasus_openlmi_unconfined processes
8
10 Security-Enhanced Linux secures the pegasus_openlmi_unconfined pro‐
11 cesses via flexible mandatory access control.
12 The pegasus_openlmi_unconfined processes execute with the pega‐
14 sus_openlmi_unconfined_t SELinux type. You can check if you have these
15 processes running by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep pegasus_openlmi_unconfined_t
20
24 The pegasus_openlmi_unconfined_t SELinux type can be entered via the
25 pegasus_openlmi_unconfined_exec_t file type.
26 The default entrypoint paths for the pegasus_openlmi_unconfined_t
28 domain are the following:
29
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 pegasus_openlmi_unconfined policy is very flexible allowing users to
40 setup their pegasus_openlmi_unconfined processes in as secure a method
41 as possible.
42 The following process types are defined for pegasus_openlmi_unconfined:
44 pegasus_openlmi_unconfined_t
46 Note: semanage permissive -a pegasus_openlmi_unconfined_t can be used
48 to make the process type pegasus_openlmi_unconfined_t permissive.
49 SELinux does not deny access to permissive process types, but the AVC
50 (SELinux denials) messages are still generated.
51
54 SELinux policy is customizable based on least access required. pega‐
55 sus_openlmi_unconfined policy is extremely flexible and has several
56 booleans that allow you to manipulate the policy and run pega‐
57 sus_openlmi_unconfined with the tightest access possible.
58 If you want to allow all daemons to write corefiles to /, you must turn
62 on the daemons_dump_core boolean. Disabled by default.
63 setsebool -P daemons_dump_core 1
65 If you want to enable cluster mode for daemons, you must turn on the
69 daemons_enable_cluster_mode boolean. Enabled by default.
70 setsebool -P daemons_enable_cluster_mode 1
72 If you want to allow all daemons to use tcp wrappers, you must turn on
76 the daemons_use_tcp_wrapper boolean. Disabled by default.
77 setsebool -P daemons_use_tcp_wrapper 1
79 If you want to allow all daemons the ability to read/write terminals,
83 you must turn on the daemons_use_tty boolean. Disabled by default.
84 setsebool -P daemons_use_tty 1
86 If you want to deny user domains applications to map a memory region as
90 both executable and writable, this is dangerous and the executable
91 should be reported in bugzilla, you must turn on the deny_execmem bool‐
92 ean. Enabled by default.
93 setsebool -P deny_execmem 1
95 If you want to deny any process from ptracing or debugging any other
99 processes, you must turn on the deny_ptrace boolean. Enabled by
100 default.
101 setsebool -P deny_ptrace 1
103 If you want to allow any process to mmap any file on system with
107 attribute file_type, you must turn on the domain_can_mmap_files bool‐
108 ean. Enabled by default.
109 setsebool -P domain_can_mmap_files 1
111 If you want to allow all domains write to kmsg_device, while kernel is
115 executed with systemd.log_target=kmsg parameter, you must turn on the
116 domain_can_write_kmsg boolean. Disabled by default.
117 setsebool -P domain_can_write_kmsg 1
119 If you want to allow all domains to use other domains file descriptors,
123 you must turn on the domain_fd_use boolean. Enabled by default.
124 setsebool -P domain_fd_use 1
126 If you want to allow all domains to have the kernel load modules, you
130 must turn on the domain_kernel_load_modules boolean. Disabled by
131 default.
132 setsebool -P domain_kernel_load_modules 1
134 If you want to allow all domains to execute in fips_mode, you must turn
138 on the fips_mode boolean. Enabled by default.
139 setsebool -P fips_mode 1
141 If you want to enable reading of urandom for all domains, you must turn
145 on the global_ssp boolean. Disabled by default.
146 setsebool -P global_ssp 1
148 If you want to control the ability to mmap a low area of the address
152 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
153 the mmap_low_allowed boolean. Disabled by default.
154 setsebool -P mmap_low_allowed 1
156 If you want to disable kernel module loading, you must turn on the
160 secure_mode_insmod boolean. Enabled by default.
161 setsebool -P secure_mode_insmod 1
163 If you want to boolean to determine whether the system permits loading
167 policy, setting enforcing mode, and changing boolean values. Set this
168 to true and you have to reboot to set it back, you must turn on the
169 secure_mode_policyload boolean. Enabled by default.
170 setsebool -P secure_mode_policyload 1
172 If you want to allow unconfined executables to make their heap memory
176 executable. Doing this is a really bad idea. Probably indicates a
177 badly coded executable, but could indicate an attack. This executable
178 should be reported in bugzilla, you must turn on the selin‐
179 uxuser_execheap boolean. Disabled by default.
180 setsebool -P selinuxuser_execheap 1
182 If you want to allow all unconfined executables to use libraries
186 requiring text relocation that are not labeled textrel_shlib_t, you
187 must turn on the selinuxuser_execmod boolean. Enabled by default.
188 setsebool -P selinuxuser_execmod 1
190 If you want to allow unconfined executables to make their stack exe‐
194 cutable. This should never, ever be necessary. Probably indicates a
195 badly coded executable, but could indicate an attack. This executable
196 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
197 stack boolean. Enabled by default.
198 setsebool -P selinuxuser_execstack 1
200 If you want to support X userspace object manager, you must turn on the
204 xserver_object_manager boolean. Enabled by default.
205 setsebool -P xserver_object_manager 1

211 The SELinux process type pegasus_openlmi_unconfined_t can manage files
212 labeled with the following file types. The paths listed are the
213 default paths for these file types. Note the processes UID still need
214 to have DAC permissions.
215 file_type
217 all files on the system
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
