NAME

6       usbmuxd_selinux  -  Security Enhanced Linux Policy for the usbmuxd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  usbmuxd  processes  via  flexible
11       mandatory access control.
12
13       The  usbmuxd processes execute with the usbmuxd_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep usbmuxd_t
20
21
22

ENTRYPOINTS

24       The  usbmuxd_t  SELinux type can be entered via the usbmuxd_exec_t file
25       type.
26
27       The default entrypoint paths for the usbmuxd_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/usbmuxd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       usbmuxd  policy  is very flexible allowing users to setup their usbmuxd
40       processes in as secure a method as possible.
41
42       The following process types are defined for usbmuxd:
43
44       usbmuxd_t
45
46       Note: semanage permissive -a usbmuxd_t can be used to make the  process
47       type  usbmuxd_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  usbmuxd
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run usbmuxd with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       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
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Enabled by default.
91
92       setsebool -P nscd_use_shm 1
93

MANAGED FILES

97       The SELinux process type usbmuxd_t can manage files  labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.
100
101       usbmuxd_var_lib_t
102
103            /var/lib/lockdown(/.*)?
104
105       usbmuxd_var_run_t
106
107            /var/run/usbmuxd.*
108
109

FILE CONTEXTS

111       SELinux requires files to have an extended attribute to define the file
112       type.
113
114       You can see the context of a file using the -Z option to ls
115
116       Policy  governs  the  access  confined  processes  have to these files.
117       SELinux usbmuxd policy is very flexible allowing users to  setup  their
118       usbmuxd processes in as secure a method as possible.
119
120       STANDARD FILE CONTEXT
121
122       SELinux  defines  the file context types for the usbmuxd, if you wanted
123       to store files with these types in a diffent paths, you need to execute
124       the  semanage  command  to  sepecify  alternate  labeling  and then use
125       restorecon to put the labels on disk.
126
127       semanage  fcontext  -a  -t   usbmuxd_unit_file_t   '/srv/myusbmuxd_con‐
128       tent(/.*)?'
129       restorecon -R -v /srv/myusbmuxd_content
130
131       Note:  SELinux  often  uses  regular expressions to specify labels that
132       match multiple files.
133
134       The following file types are defined for usbmuxd:
135
136
137
138       usbmuxd_exec_t
139
140       - Set files with the usbmuxd_exec_t type, if you want to transition  an
141       executable to the usbmuxd_t domain.
142
143
144
145       usbmuxd_unit_file_t
146
147       - Set files with the usbmuxd_unit_file_t type, if you want to treat the
148       files as usbmuxd unit content.
149
150
151
152       usbmuxd_var_lib_t
153
154       - Set files with the usbmuxd_var_lib_t type, if you want to  store  the
155       usbmuxd files under the /var/lib directory.
156
157
158
159       usbmuxd_var_run_t
160
161       -  Set  files with the usbmuxd_var_run_t type, if you want to store the
162       usbmuxd files under the /run or /var/run directory.
163
164
165
166       Note: File context can be temporarily modified with the chcon  command.
167       If  you want to permanently change the file context you need to use the
168       semanage fcontext command.  This will modify the SELinux labeling data‐
169       base.  You will need to use restorecon to apply the labels.

171

COMMANDS

173       semanage  fcontext  can also be used to manipulate default file context
174       mappings.
175
176       semanage permissive can also be used to manipulate  whether  or  not  a
177       process type is permissive.
178
179       semanage  module can also be used to enable/disable/install/remove pol‐
180       icy modules.
181
182       semanage boolean can also be used to manipulate the booleans
183
184
185       system-config-selinux is a GUI tool available to customize SELinux pol‐
186       icy settings.
