6 modemmanager_selinux - Security Enhanced Linux Policy for the modemman‐
7 ager processes
8
10 Security-Enhanced Linux secures the modemmanager processes via flexible
11 mandatory access control.
12 The modemmanager processes execute with the modemmanager_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep modemmanager_t
20
24 The modemmanager_t SELinux type can be entered via the modemman‐
25 ager_exec_t file type.
26 The default entrypoint paths for the modemmanager_t domain are the fol‐
28 lowing:
29 /usr/sbin/ModemManager, /usr/sbin/modem-manager
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 modemmanager policy is very flexible allowing users to setup their
40 modemmanager processes in as secure a method as possible.
41 The following process types are defined for modemmanager:
43 modemmanager_t
45 Note: semanage permissive -a modemmanager_t can be used to make the
47 process type modemmanager_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. modem‐
54 manager policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run modemmanager with the tight‐
56 est access possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 The SELinux process type modemmanager_t can manage files labeled with
69 the following file types. The paths listed are the default paths for
70 these file types. Note the processes UID still need to have DAC per‐
71 missions.

123 SELinux requires files to have an extended attribute to define the file
124 type.
125 You can see the context of a file using the -Z option to ls
127 Policy governs the access confined processes have to these files.
129 SELinux modemmanager policy is very flexible allowing users to setup
130 their modemmanager processes in as secure a method as possible.
131 STANDARD FILE CONTEXT
133 SELinux defines the file context types for the modemmanager, if you
135 wanted to store files with these types in a diffent paths, you need to
136 execute the semanage command to sepecify alternate labeling and then
137 use restorecon to put the labels on disk.
138 semanage fcontext -a -t modemmanager_unit_file_t '/srv/mymodemman‐
140 ager_content(/.*)?'
141 restorecon -R -v /srv/mymodemmanager_content
142 Note: SELinux often uses regular expressions to specify labels that
144 match multiple files.
145 The following file types are defined for modemmanager:
147 modemmanager_exec_t
151 - Set files with the modemmanager_exec_t type, if you want to transi‐
153 tion an executable to the modemmanager_t domain.
154 Paths:
157 /usr/sbin/ModemManager, /usr/sbin/modem-manager
158 modemmanager_unit_file_t
161 - Set files with the modemmanager_unit_file_t type, if you want to
163 treat the files as modemmanager unit content.
164 Note: File context can be temporarily modified with the chcon command.
168 If you want to permanently change the file context you need to use the
169 semanage fcontext command. This will modify the SELinux labeling data‐
170 base. You will need to use restorecon to apply the labels.
171
174 semanage fcontext can also be used to manipulate default file context
175 mappings.
176 semanage permissive can also be used to manipulate whether or not a
178 process type is permissive.
179 semanage module can also be used to enable/disable/install/remove pol‐
181 icy modules.
182 semanage boolean can also be used to manipulate the booleans
184 system-config-selinux is a GUI tool available to customize SELinux pol‐
187 icy settings.
