NAME

6       tethereal_selinux  -  Security  Enhanced Linux Policy for the tethereal
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the tethereal  processes  via  flexible
11       mandatory access control.
12
13       The  tethereal processes execute with the tethereal_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 tethereal_t
20
21
22

ENTRYPOINTS

24       The  tethereal_t  SELinux  type can be entered via the tethereal_exec_t
25       file type.
26
27       The default entrypoint paths for the tethereal_t domain are the follow‐
28       ing:
29
30       /usr/sbin/tethereal.*
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       tethereal  policy is very flexible allowing users to setup their tethe‐
40       real processes in as secure a method as possible.
41
42       The following process types are defined for tethereal:
43
44       tethereal_t
45
46       Note: semanage permissive -a  tethereal_t  can  be  used  to  make  the
47       process  type  tethereal_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy is customizable based on least access required.  tethe‐
54       real policy is extremely flexible and has several booleans  that  allow
55       you to manipulate the policy and run tethereal 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 allow all domains to have the kernel load  modules,  you
75       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
76       default.
77
78       setsebool -P domain_kernel_load_modules 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If you want to enable reading of urandom for all domains, you must turn
90       on the global_ssp boolean. Disabled by default.
91
92       setsebool -P global_ssp 1
93

95

MANAGED FILES

97       The SELinux process type tethereal_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       initrc_tmp_t
102
103
104       mnt_t
105
106            /mnt(/[^/]*)
107            /mnt(/[^/]*)?
108            /rhev(/[^/]*)?
109            /media(/[^/]*)
110            /media(/[^/]*)?
111            /etc/rhgb(/.*)?
112            /media/.hal-.*
113            /net
114            /afs
115            /rhev
116            /misc
117
118       tethereal_tmp_t
119
120
121       tmp_t
122
123            /tmp
124            /usr/tmp
125            /var/tmp
126            /tmp-inst
127            /var/tmp-inst
128            /var/tmp/vi.recover

FILE CONTEXTS

132       SELinux requires files to have an extended attribute to define the file
133       type.
134
135       You can see the context of a file using the -Z option to ls
136
137       Policy  governs  the  access  confined  processes  have to these files.
138       SELinux tethereal policy is very flexible allowing users to setup their
139       tethereal processes in as secure a method as possible.
140
141       STANDARD FILE CONTEXT
142
143       SELinux defines the file context types for the tethereal, if you wanted
144       to store files with these types in a diffent paths, you need to execute
145       the  semanage  command  to  sepecify  alternate  labeling  and then use
146       restorecon to put the labels on disk.
147
148       semanage  fcontext   -a   -t   tethereal_tmp_t   '/srv/mytethereal_con‐
149       tent(/.*)?'
150       restorecon -R -v /srv/mytethereal_content
151
152       Note:  SELinux  often  uses  regular expressions to specify labels that
153       match multiple files.
154
155       The following file types are defined for tethereal:
156
157
158
159       tethereal_exec_t
160
161       - Set files with the tethereal_exec_t type, if you want  to  transition
162       an executable to the tethereal_t domain.
163
164
165
166       tethereal_tmp_t
167
168       -  Set files with the tethereal_tmp_t type, if you want to store tethe‐
169       real temporary files in the /tmp directories.
170
171
172
173       Note: File context can be temporarily modified with the chcon  command.
174       If  you want to permanently change the file context you need to use the
175       semanage fcontext command.  This will modify the SELinux labeling data‐
176       base.  You will need to use restorecon to apply the labels.
177
178

COMMANDS

180       semanage  fcontext  can also be used to manipulate default file context
181       mappings.
182
183       semanage permissive can also be used to manipulate  whether  or  not  a
184       process type is permissive.
185
186       semanage  module can also be used to enable/disable/install/remove pol‐
187       icy modules.
188
189       semanage boolean can also be used to manipulate the booleans
190
191
192       system-config-selinux is a GUI tool available to customize SELinux pol‐
193       icy settings.
