NAME

6       avahi_selinux - Security Enhanced Linux Policy for the avahi processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The avahi_t SELinux type can be entered via the avahi_exec_t file type.
24
25       The default entrypoint paths for the avahi_t domain are the following:
26
27       /usr/sbin/avahi-daemon,    /usr/sbin/avahi-autoipd,    /usr/sbin/avahi-
28       dnsconfd
29

PROCESS TYPES

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

BOOLEANS

51       SELinux  policy  is customizable based on least access required.  avahi
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run avahi with the tightest access possible.
54
55
56
57       If you want to allow all domains to execute in fips_mode, you must turn
58       on the fips_mode boolean. Enabled by default.
59
60       setsebool -P fips_mode 1
61
62
63
64       If you want to allow Apache to communicate with avahi service via dbus,
65       you must turn on the httpd_dbus_avahi boolean. Disabled by default.
66
67       setsebool -P httpd_dbus_avahi 1

MANAGED FILES

72       The SELinux process type avahi_t can manage files labeled with the fol‐
73       lowing file types.  The paths listed are the default  paths  for  these
74       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

136       SELinux requires files to have an extended attribute to define the file
137       type.
138
139       You can see the context of a file using the -Z option to ls
140
141       Policy governs the access  confined  processes  have  to  these  files.
142       SELinux  avahi  policy  is  very flexible allowing users to setup their
143       avahi processes in as secure a method as possible.
144
145       STANDARD FILE CONTEXT
146
147       SELinux defines the file context types for the avahi, if you wanted  to
148       store  files  with  these types in a diffent paths, you need to execute
149       the semanage command to specify alternate labeling  and  then  use  re‐
150       storecon to put the labels on disk.
151
152       semanage fcontext -a -t avahi_unit_file_t '/srv/myavahi_content(/.*)?'
153       restorecon -R -v /srv/myavahi_content
154
155       Note:  SELinux  often  uses  regular expressions to specify labels that
156       match multiple files.
157
158       The following file types are defined for avahi:
159
160
161
162       avahi_conf_t
163
164       - Set files with the avahi_conf_t type, if you want to treat the  files
165       as avahi configuration data, usually stored under the /etc directory.
166
167
168
169       avahi_exec_t
170
171       -  Set  files  with the avahi_exec_t type, if you want to transition an
172       executable to the avahi_t domain.
173
174
175       Paths:
176            /usr/sbin/avahi-daemon, /usr/sbin/avahi-autoipd,  /usr/sbin/avahi-
177            dnsconfd
178
179
180       avahi_initrc_exec_t
181
182       -  Set  files with the avahi_initrc_exec_t type, if you want to transi‐
183       tion an executable to the avahi_initrc_t domain.
184
185
186
187       avahi_unit_file_t
188
189       - Set files with the avahi_unit_file_t type, if you want to  treat  the
190       files as avahi unit content.
191
192
193
194       avahi_var_lib_t
195
196       -  Set  files  with  the avahi_var_lib_t type, if you want to store the
197       avahi files under the /var/lib directory.
198
199
200
201       avahi_var_run_t
202
203       - Set files with the avahi_var_run_t type, if you  want  to  store  the
204       avahi files under the /run or /var/run directory.
205
206
207
208       Note:  File context can be temporarily modified with the chcon command.
209       If you want to permanently change the file context you need to use  the
210       semanage fcontext command.  This will modify the SELinux labeling data‐
211       base.  You will need to use restorecon to apply the labels.
212
213

COMMANDS

215       semanage fcontext can also be used to manipulate default  file  context
216       mappings.
217
218       semanage  permissive  can  also  be used to manipulate whether or not a
219       process type is permissive.
220
221       semanage module can also be used to enable/disable/install/remove  pol‐
222       icy modules.
223
224       semanage boolean can also be used to manipulate the booleans
225
226
227       system-config-selinux is a GUI tool available to customize SELinux pol‐
228       icy settings.
