6 conman_unconfined_script_selinux - Security Enhanced Linux Policy for
7 the conman_unconfined_script processes
8
10 Security-Enhanced Linux secures the conman_unconfined_script processes
11 via flexible mandatory access control.
12 The conman_unconfined_script processes execute with the conman_uncon‐
14 fined_script_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 conman_unconfined_script_t
20
24 The conman_unconfined_script_t SELinux type can be entered via the con‐
25 man_unconfined_script_exec_t file type.
26 The default entrypoint paths for the conman_unconfined_script_t domain
28 are the following:
29 /usr/share/conman/exec(/.*)?
31
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 conman_unconfined_script policy is very flexible allowing users to set‐
40 up their conman_unconfined_script processes in as secure a method as
41 possible.
42 The following process types are defined for conman_unconfined_script:
44 conman_unconfined_script_t
46 Note: semanage permissive -a conman_unconfined_script_t can be used to
48 make the process type conman_unconfined_script_t permissive. SELinux
49 does not deny access to permissive process types, but the AVC (SELinux
50 denials) messages are still generated.
51
54 SELinux policy is customizable based on least access required. con‐
55 man_unconfined_script policy is extremely flexible and has several
56 booleans that allow you to manipulate the policy and run conman_uncon‐
57 fined_script with the tightest access possible.
58 If you want to allow all daemons the ability to read/write terminals,
62 you must turn on the daemons_use_tty boolean. Disabled by default.
63 setsebool -P daemons_use_tty 1
65 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Enabled by default.
72 setsebool -P deny_execmem 1
74 If you want to deny any process from ptracing or debugging any other
78 processes, you must turn on the deny_ptrace boolean. Enabled by
79 default.
80 setsebool -P deny_ptrace 1
82 If you want to allow any process to mmap any file on system with
86 attribute file_type, you must turn on the domain_can_mmap_files bool‐
87 ean. Enabled by default.
88 setsebool -P domain_can_mmap_files 1
90 If you want to allow all domains write to kmsg_device, while kernel is
94 executed with systemd.log_target=kmsg parameter, you must turn on the
95 domain_can_write_kmsg boolean. Disabled by default.
96 setsebool -P domain_can_write_kmsg 1
98 If you want to allow all domains to use other domains file descriptors,
102 you must turn on the domain_fd_use boolean. Enabled by default.
103 setsebool -P domain_fd_use 1
105 If you want to allow all domains to have the kernel load modules, you
109 must turn on the domain_kernel_load_modules boolean. Disabled by
110 default.
111 setsebool -P domain_kernel_load_modules 1
113 If you want to allow all domains to execute in fips_mode, you must turn
117 on the fips_mode boolean. Enabled by default.
118 setsebool -P fips_mode 1
120 If you want to enable reading of urandom for all domains, you must turn
124 on the global_ssp boolean. Disabled by default.
125 setsebool -P global_ssp 1
127 If you want to control the ability to mmap a low area of the address
131 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
132 the mmap_low_allowed boolean. Disabled by default.
133 setsebool -P mmap_low_allowed 1
135 If you want to disable kernel module loading, you must turn on the
139 secure_mode_insmod boolean. Enabled by default.
140 setsebool -P secure_mode_insmod 1
142 If you want to boolean to determine whether the system permits loading
146 policy, setting enforcing mode, and changing boolean values. Set this
147 to true and you have to reboot to set it back, you must turn on the
148 secure_mode_policyload boolean. Enabled by default.
149 setsebool -P secure_mode_policyload 1
151 If you want to allow unconfined executables to make their heap memory
155 executable. Doing this is a really bad idea. Probably indicates a
156 badly coded executable, but could indicate an attack. This executable
157 should be reported in bugzilla, you must turn on the selin‐
158 uxuser_execheap boolean. Disabled by default.
159 setsebool -P selinuxuser_execheap 1
161 If you want to allow all unconfined executables to use libraries
165 requiring text relocation that are not labeled textrel_shlib_t, you
166 must turn on the selinuxuser_execmod boolean. Enabled by default.
167 setsebool -P selinuxuser_execmod 1
169 If you want to allow unconfined executables to make their stack exe‐
173 cutable. This should never, ever be necessary. Probably indicates a
174 badly coded executable, but could indicate an attack. This executable
175 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
176 stack boolean. Enabled by default.
177 setsebool -P selinuxuser_execstack 1
179 If you want to support X userspace object manager, you must turn on the
183 xserver_object_manager boolean. Enabled by default.
184 setsebool -P xserver_object_manager 1

190 The SELinux process type conman_unconfined_script_t can manage files
191 labeled with the following file types. The paths listed are the
192 default paths for these file types. Note the processes UID still need
193 to have DAC permissions.
194 file_type
196 all files on the system
198
201 SELinux requires files to have an extended attribute to define the file
202 type.
203 You can see the context of a file using the -Z option to ls
205 Policy governs the access confined processes have to these files.
207 SELinux conman_unconfined_script policy is very flexible allowing users
208 to setup their conman_unconfined_script processes in as secure a method
209 as possible.
210 The following file types are defined for conman_unconfined_script:
212 conman_unconfined_script_exec_t
216 - Set files with the conman_unconfined_script_exec_t type, if you want
218 to transition an executable to the conman_unconfined_script_t domain.
219 Note: File context can be temporarily modified with the chcon command.
223 If you want to permanently change the file context you need to use the
224 semanage fcontext command. This will modify the SELinux labeling data‐
225 base. You will need to use restorecon to apply the labels.
226
229 semanage fcontext can also be used to manipulate default file context
230 mappings.
231 semanage permissive can also be used to manipulate whether or not a
233 process type is permissive.
234 semanage module can also be used to enable/disable/install/remove pol‐
236 icy modules.
237 semanage boolean can also be used to manipulate the booleans
239 system-config-selinux is a GUI tool available to customize SELinux pol‐
242 icy settings.
