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

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
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.
