NAME

6       obex_selinux - Security Enhanced Linux Policy for the obex processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The obex_t SELinux type can be entered via the obex_exec_t file type.
24
25       The default entrypoint paths for the obex_t domain are the following:
26
27       /usr/bin/obex-data-server, /usr/libexec/bluetooth/obexd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       obex policy is very flexible allowing users to setup  their  obex  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for obex:
40
41       obex_t
42
43       Note:  semanage  permissive  -a  obex_t can be used to make the process
44       type obex_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   obex
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run obex with the tightest access possible.
53
54
55
56       If you want to deny any process from ptracing or  debugging  any  other
57       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
58       default.
59
60       setsebool -P deny_ptrace 1
61
62
63
64       If you want to allow any process  to  mmap  any  file  on  system  with
65       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
66       ean. Enabled by default.
67
68       setsebool -P domain_can_mmap_files 1
69
70
71
72       If you want to allow all domains write to kmsg_device, while kernel  is
73       executed  with  systemd.log_target=kmsg parameter, you must turn on the
74       domain_can_write_kmsg boolean. Disabled by default.
75
76       setsebool -P domain_can_write_kmsg 1
77
78
79
80       If you want to allow all domains to use other domains file descriptors,
81       you must turn on the domain_fd_use boolean. Enabled by default.
82
83       setsebool -P domain_fd_use 1
84
85
86
87       If  you  want to allow all domains to have the kernel load modules, you
88       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
89       default.
90
91       setsebool -P domain_kernel_load_modules 1
92
93
94
95       If you want to allow all domains to execute in fips_mode, you must turn
96       on the fips_mode boolean. Enabled by default.
97
98       setsebool -P fips_mode 1
99
100
101
102       If you want to enable reading of urandom for all domains, you must turn
103       on the global_ssp boolean. Disabled by default.
104
105       setsebool -P global_ssp 1
106
107
108

FILE CONTEXTS

110       SELinux requires files to have an extended attribute to define the file
111       type.
112
113       You can see the context of a file using the -Z option to ls
114
115       Policy governs the access  confined  processes  have  to  these  files.
116       SELinux obex policy is very flexible allowing users to setup their obex
117       processes in as secure a method as possible.
118
119       The following file types are defined for obex:
120
121
122
123       obex_exec_t
124
125       - Set files with the obex_exec_t type, if you  want  to  transition  an
126       executable to the obex_t domain.
127
128
129       Paths:
130            /usr/bin/obex-data-server, /usr/libexec/bluetooth/obexd
131
132
133       Note:  File context can be temporarily modified with the chcon command.
134       If you want to permanently change the file context you need to use  the
135       semanage fcontext command.  This will modify the SELinux labeling data‐
136       base.  You will need to use restorecon to apply the labels.
137
138

COMMANDS

140       semanage fcontext can also be used to manipulate default  file  context
141       mappings.
142
143       semanage  permissive  can  also  be used to manipulate whether or not a
144       process type is permissive.
145
146       semanage module can also be used to enable/disable/install/remove  pol‐
147       icy modules.
148
149       semanage boolean can also be used to manipulate the booleans
150
151
152       system-config-selinux is a GUI tool available to customize SELinux pol‐
153       icy settings.
