NAME

6       ethereal_selinux - Security Enhanced Linux Policy for the ethereal pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The ethereal_t SELinux type can be entered via the ethereal_exec_t file
25       type.
26
27       The default entrypoint paths for the ethereal_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/ethereal.*
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       ethereal policy is very flexible allowing users to setup their ethereal
40       processes in as secure a method as possible.
41
42       The following process types are defined for ethereal:
43
44       ethereal_t
45
46       Note: semanage permissive -a ethereal_t can be used to make the process
47       type  ethereal_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.  ethe‐
54       real policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run ethereal with the tightest access
56       possible.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you want to allow sysadm to debug or ptrace all processes, you must
68       turn on the allow_ptrace boolean. Disabled by default.
69
70       setsebool -P allow_ptrace 1
71
72
73
74       If you want to allows clients to write to the X  server  shared  memory
75       segments,  you  must  turn on the allow_write_xshm boolean. Disabled by
76       default.
77
78       setsebool -P allow_write_xshm 1
79
80
81
82       If you want to allow all domains to have the kernel load  modules,  you
83       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
84       default.
85
86       setsebool -P domain_kernel_load_modules 1
87
88
89
90       If you want to allow all domains to execute in fips_mode, you must turn
91       on the fips_mode boolean. Enabled by default.
92
93       setsebool -P fips_mode 1
94
95
96
97       If you want to enable reading of urandom for all domains, you must turn
98       on the global_ssp boolean. Disabled by default.
99
100       setsebool -P global_ssp 1
101
102
103
104       If you want to support NFS home  directories,  you  must  turn  on  the
105       use_nfs_home_dirs boolean. Disabled by default.
106
107       setsebool -P use_nfs_home_dirs 1
108
109
110
111       If  you  want  to  support SAMBA home directories, you must turn on the
112       use_samba_home_dirs boolean. Disabled by default.
113
114       setsebool -P use_samba_home_dirs 1
115
116
117
118       If you want to support X userspace object manager, you must turn on the
119       xserver_object_manager boolean. Disabled by default.
120
121       setsebool -P xserver_object_manager 1
122
123
124

MANAGED FILES

126       The  SELinux  process type ethereal_t can manage files labeled with the
127       following file types.  The paths listed are the default paths for these
128       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

192       SELinux requires files to have an extended attribute to define the file
193       type.
194
195       You can see the context of a file using the -Z option to ls
196
197       Policy governs the access  confined  processes  have  to  these  files.
198       SELinux  ethereal policy is very flexible allowing users to setup their
199       ethereal processes in as secure a method as possible.
200
201       STANDARD FILE CONTEXT
202
203       SELinux defines the file context types for the ethereal, if you  wanted
204       to store files with these types in a diffent paths, you need to execute
205       the semanage command  to  sepecify  alternate  labeling  and  then  use
206       restorecon to put the labels on disk.
207
208       semanage   fcontext   -a   -t   ethereal_tmpfs_t  '/srv/myethereal_con‐
209       tent(/.*)?'
210       restorecon -R -v /srv/myethereal_content
211
212       Note: SELinux often uses regular expressions  to  specify  labels  that
213       match multiple files.
214
215       The following file types are defined for ethereal:
216
217
218
219       ethereal_exec_t
220
221       - Set files with the ethereal_exec_t type, if you want to transition an
222       executable to the ethereal_t domain.
223
224
225
226       ethereal_home_t
227
228       - Set files with the ethereal_home_t type, if you want to  store  ethe‐
229       real files in the users home directory.
230
231
232       Paths:
233            /home/[^/]*/.ethereal(/.*)?, /home/staff/.ethereal(/.*)?
234
235
236       ethereal_tmp_t
237
238       - Set files with the ethereal_tmp_t type, if you want to store ethereal
239       temporary files in the /tmp directories.
240
241
242
243       ethereal_tmpfs_t
244
245       - Set files with the ethereal_tmpfs_t type, if you want to store  ethe‐
246       real files on a tmpfs file system.
247
248
249
250       Note:  File context can be temporarily modified with the chcon command.
251       If you want to permanently change the file context you need to use  the
252       semanage fcontext command.  This will modify the SELinux labeling data‐
253       base.  You will need to use restorecon to apply the labels.
254
255

COMMANDS

257       semanage fcontext can also be used to manipulate default  file  context
258       mappings.
259
260       semanage  permissive  can  also  be used to manipulate whether or not a
261       process type is permissive.
262
263       semanage module can also be used to enable/disable/install/remove  pol‐
264       icy modules.
265
266       semanage boolean can also be used to manipulate the booleans
267
268
269       system-config-selinux is a GUI tool available to customize SELinux pol‐
270       icy settings.
