6 munin_unconfined_plugin_selinux - Security Enhanced Linux Policy for
7 the munin_unconfined_plugin processes
8
10 Security-Enhanced Linux secures the munin_unconfined_plugin processes
11 via flexible mandatory access control.
12 The munin_unconfined_plugin processes execute with the munin_uncon‐
14 fined_plugin_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep munin_unconfined_plugin_t
20
24 The munin_unconfined_plugin_t SELinux type can be entered via the
25 file_type, unlabeled_t, proc_type, filesystem_type, munin_uncon‐
26 fined_plugin_exec_t, mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the munin_unconfined_plugin_t domain
29 are the following:
30 all files on the system, /usr/share/munin/plugins/.*, /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 munin_unconfined_plugin policy is very flexible allowing users to setup
41 their munin_unconfined_plugin processes in as secure a method as possi‐
42 ble.
43 The following process types are defined for munin_unconfined_plugin:
45 munin_unconfined_plugin_t
47 Note: semanage permissive -a munin_unconfined_plugin_t can be used to
49 make the process type munin_unconfined_plugin_t permissive. SELinux
50 does not deny access to permissive process types, but the AVC (SELinux
51 denials) messages are still generated.
52
55 SELinux policy is customizable based on least access required.
56 munin_unconfined_plugin policy is extremely flexible and has several
57 booleans that allow you to manipulate the policy and run munin_uncon‐
58 fined_plugin with the tightest access possible.
59 If you want to allow all domains to use other domains file descriptors,
63 you must turn on the allow_domain_fd_use boolean. Enabled by default.
64 setsebool -P allow_domain_fd_use 1
66 If you want to allow unconfined executables to make their heap memory
70 executable. Doing this is a really bad idea. Probably indicates a
71 badly coded executable, but could indicate an attack. This executable
72 should be reported in bugzilla, you must turn on the allow_execheap
73 boolean. Disabled by default.
74 setsebool -P allow_execheap 1
76 If you want to allow unconfined executables to map a memory region as
80 both executable and writable, this is dangerous and the executable
81 should be reported in bugzilla), you must turn on the allow_execmem
82 boolean. Enabled by default.
83 setsebool -P allow_execmem 1
85 If you want to allow all unconfined executables to use libraries
89 requiring text relocation that are not labeled textrel_shlib_t), you
90 must turn on the allow_execmod boolean. Enabled by default.
91 setsebool -P allow_execmod 1
93 If you want to allow unconfined executables to make their stack exe‐
97 cutable. This should never, ever be necessary. Probably indicates a
98 badly coded executable, but could indicate an attack. This executable
99 should be reported in bugzilla), you must turn on the allow_execstack
100 boolean. Enabled by default.
101 setsebool -P allow_execstack 1
103 If you want to allow sysadm to debug or ptrace all processes, you must
107 turn on the allow_ptrace boolean. Disabled by default.
108 setsebool -P allow_ptrace 1
110 If you want to allow all domains to have the kernel load modules, you
114 must turn on the domain_kernel_load_modules boolean. Disabled by
115 default.
116 setsebool -P domain_kernel_load_modules 1
118 If you want to allow all domains to execute in fips_mode, you must turn
122 on the fips_mode boolean. Enabled by default.
123 setsebool -P fips_mode 1
125 If you want to enable reading of urandom for all domains, you must turn
129 on the global_ssp boolean. Disabled by default.
130 setsebool -P global_ssp 1
132 If you want to allow certain domains to map low memory in the kernel,
136 you must turn on the mmap_low_allowed boolean. Disabled by default.
137 setsebool -P mmap_low_allowed 1
139 If you want to boolean to determine whether the system permits loading
143 policy, setting enforcing mode, and changing boolean values. Set this
144 to true and you have to reboot to set it back, you must turn on the
145 secure_mode_policyload boolean. Disabled by default.
146 setsebool -P secure_mode_policyload 1
148 If you want to support X userspace object manager, you must turn on the
152 xserver_object_manager boolean. Disabled by default.
153 setsebool -P xserver_object_manager 1
155
159 The SELinux process type munin_unconfined_plugin_t can manage files
160 labeled with the following file types. The paths listed are the
161 default paths for these file types. Note the processes UID still need
162 to have DAC permissions.
163 file_type
165 all files on the system
167
170 SELinux requires files to have an extended attribute to define the file
171 type.
172 You can see the context of a file using the -Z option to ls
174 Policy governs the access confined processes have to these files.
176 SELinux munin_unconfined_plugin policy is very flexible allowing users
177 to setup their munin_unconfined_plugin processes in as secure a method
178 as possible.
179 STANDARD FILE CONTEXT
181 SELinux defines the file context types for the munin_unconfined_plugin,
183 if you wanted to store files with these types in a diffent paths, you
184 need to execute the semanage command to sepecify alternate labeling and
185 then use restorecon to put the labels on disk.
186 semanage fcontext -a -t munin_unconfined_plugin_tmp_t
188 '/srv/mymunin_unconfined_plugin_content(/.*)?'
189 restorecon -R -v /srv/mymunin_unconfined_plugin_content
190 Note: SELinux often uses regular expressions to specify labels that
192 match multiple files.
193 The following file types are defined for munin_unconfined_plugin:
195 munin_unconfined_plugin_exec_t
199 - Set files with the munin_unconfined_plugin_exec_t type, if you want
201 to transition an executable to the munin_unconfined_plugin_t domain.
202 munin_unconfined_plugin_tmp_t
206 - Set files with the munin_unconfined_plugin_tmp_t type, if you want to
208 store munin unconfined plugin temporary files in the /tmp directories.
209 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
