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
40 setup 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 deny user domains applications to map a memory region as
62 both executable and writable, this is dangerous and the executable
63 should be reported in bugzilla, you must turn on the deny_execmem bool‐
64 ean. Disabled by default.
65 setsebool -P deny_execmem 1
67 If you want to control the ability to mmap a low area of the address
71 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
72 the mmap_low_allowed boolean. Disabled by default.
73 setsebool -P mmap_low_allowed 1
75 If you want to disable kernel module loading, you must turn on the se‐
79 cure_mode_insmod boolean. Disabled by default.
80 setsebool -P secure_mode_insmod 1
82 If you want to allow unconfined executables to make their heap memory
86 executable. Doing this is a really bad idea. Probably indicates a
87 badly coded executable, but could indicate an attack. This executable
88 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
89 echeap boolean. Disabled by default.
90 setsebool -P selinuxuser_execheap 1
92 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
99 stack boolean. Enabled by default.
100 setsebool -P selinuxuser_execstack 1

106 The SELinux process type conman_unconfined_script_t can manage files
107 labeled with the following file types. The paths listed are the de‐
108 fault paths for these file types. Note the processes UID still need to
109 have DAC permissions.
110 file_type
112 all files on the system
114
117 SELinux requires files to have an extended attribute to define the file
118 type.
119 You can see the context of a file using the -Z option to ls
121 Policy governs the access confined processes have to these files.
123 SELinux conman_unconfined_script policy is very flexible allowing users
124 to setup their conman_unconfined_script processes in as secure a method
125 as possible.
126 STANDARD FILE CONTEXT
128 SELinux defines the file context types for the conman_uncon‐
130 fined_script, if you wanted to store files with these types in a dif‐
131 ferent paths, you need to execute the semanage command to specify al‐
132 ternate labeling and then use restorecon to put the labels on disk.
133 semanage fcontext -a -t conman_unconfined_script_exec_t '/srv/con‐
135 man_unconfined_script/content(/.*)?'
136 restorecon -R -v /srv/myconman_unconfined_script_content
137 Note: SELinux often uses regular expressions to specify labels that
139 match multiple files.
140 The following file types are defined for conman_unconfined_script:
142 conman_unconfined_script_exec_t
146 - Set files with the conman_unconfined_script_exec_t type, if you want
148 to transition an executable to the conman_unconfined_script_t domain.
149 Note: File context can be temporarily modified with the chcon command.
153 If you want to permanently change the file context you need to use the
154 semanage fcontext command. This will modify the SELinux labeling data‐
155 base. You will need to use restorecon to apply the labels.
156
159 semanage fcontext can also be used to manipulate default file context
160 mappings.
161 semanage permissive can also be used to manipulate whether or not a
163 process type is permissive.
164 semanage module can also be used to enable/disable/install/remove pol‐
166 icy modules.
167 semanage boolean can also be used to manipulate the booleans
169 system-config-selinux is a GUI tool available to customize SELinux pol‐
172 icy settings.
