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 al‐
55 low you to manipulate the policy and run modemmanager with the tightest
56 access possible.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72
76 The SELinux process type modemmanager_t can manage files labeled with
77 the following file types. The paths listed are the default paths for
78 these file types. Note the processes UID still need to have DAC per‐
79 missions.

132 SELinux requires files to have an extended attribute to define the file
133 type.
134 You can see the context of a file using the -Z option to ls
136 Policy governs the access confined processes have to these files.
138 SELinux modemmanager policy is very flexible allowing users to setup
139 their modemmanager processes in as secure a method as possible.
140 STANDARD FILE CONTEXT
142 SELinux defines the file context types for the modemmanager, if you
144 wanted to store files with these types in a different paths, you need
145 to execute the semanage command to specify alternate labeling and then
146 use restorecon to put the labels on disk.
147 semanage fcontext -a -t modemmanager_exec_t '/srv/modemmanager/con‐
149 tent(/.*)?'
150 restorecon -R -v /srv/mymodemmanager_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for modemmanager:
156 modemmanager_exec_t
160 - Set files with the modemmanager_exec_t type, if you want to transi‐
162 tion an executable to the modemmanager_t domain.
163 Paths:
166 /usr/sbin/ModemManager, /usr/sbin/modem-manager
167 modemmanager_unit_file_t
170 - Set files with the modemmanager_unit_file_t type, if you want to
172 treat the files as modemmanager unit content.
173 Note: File context can be temporarily modified with the chcon command.
177 If you want to permanently change the file context you need to use the
178 semanage fcontext command. This will modify the SELinux labeling data‐
179 base. You will need to use restorecon to apply the labels.
180
183 semanage fcontext can also be used to manipulate default file context
184 mappings.
185 semanage permissive can also be used to manipulate whether or not a
187 process type is permissive.
188 semanage module can also be used to enable/disable/install/remove pol‐
190 icy modules.
191 semanage boolean can also be used to manipulate the booleans
193 system-config-selinux is a GUI tool available to customize SELinux pol‐
196 icy settings.
