NAME

6       varnishd_selinux - Security Enhanced Linux Policy for the varnishd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  varnishd  processes  via  flexible
11       mandatory access control.
12
13       The  varnishd  processes  execute with the varnishd_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 varnishd_t
20
21
22

ENTRYPOINTS

24       The varnishd_t SELinux type can be entered via the varnishd_exec_t file
25       type.
26
27       The default entrypoint paths for the varnishd_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/varnishd
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       varnishd policy is very flexible allowing users to setup their varnishd
40       processes in as secure a method as possible.
41
42       The following process types are defined for varnishd:
43
44       varnishd_t
45
46       Note: semanage permissive -a varnishd_t can be used to make the process
47       type  varnishd_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.  var‐
54       nishd policy is extremely flexible and has several booleans that  allow
55       you  to manipulate the policy and run varnishd with the tightest access
56       possible.
57
58
59
60       If you want to determine whether varnishd can use the full TCP network,
61       you must turn on the varnishd_connect_any boolean. Disabled by default.
62
63       setsebool -P varnishd_connect_any 1
64
65
66
67       If you want to allow users to resolve user passwd entries directly from
68       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
69       gin_nsswitch_use_ldap boolean. Disabled by default.
70
71       setsebool -P authlogin_nsswitch_use_ldap 1
72
73
74
75       If you want to allow all domains to execute in fips_mode, you must turn
76       on the fips_mode boolean. Enabled by default.
77
78       setsebool -P fips_mode 1
79
80
81
82       If you want to allow confined applications to run  with  kerberos,  you
83       must turn on the kerberos_enabled boolean. Disabled by default.
84
85       setsebool -P kerberos_enabled 1
86
87
88
89       If  you  want  to  allow  system  to run with NIS, you must turn on the
90       nis_enabled boolean. Disabled by default.
91
92       setsebool -P nis_enabled 1
93
94
95
96       If you want to allow confined applications to use nscd  shared  memory,
97       you must turn on the nscd_use_shm boolean. Disabled by default.
98
99       setsebool -P nscd_use_shm 1
100
101
102

PORT TYPES

104       SELinux defines port types to represent TCP and UDP ports.
105
106       You  can  see  the  types associated with a port by using the following
107       command:
108
109       semanage port -l
110
111
112       Policy governs the access  confined  processes  have  to  these  ports.
113       SELinux  varnishd policy is very flexible allowing users to setup their
114       varnishd processes in as secure a method as possible.
115
116       The following port types are defined for varnishd:
117
118
119       varnishd_port_t
120
121
122
123       Default Defined Ports:
124                 tcp 6081-6082
125

MANAGED FILES

127       The SELinux process type varnishd_t can manage files labeled  with  the
128       following file types.  The paths listed are the default paths for these
129       file types.  Note the processes UID still need to have DAC permissions.
130
131       cluster_conf_t

FILE CONTEXTS

179       SELinux requires files to have an extended attribute to define the file
180       type.
181
182       You can see the context of a file using the -Z option to ls
183
184       Policy  governs  the  access  confined  processes  have to these files.
185       SELinux varnishd policy is very flexible allowing users to setup  their
186       varnishd processes in as secure a method as possible.
187
188       STANDARD FILE CONTEXT
189
190       SELinux  defines the file context types for the varnishd, if you wanted
191       to store files with these types in a diffent paths, you need to execute
192       the  semanage  command  to  sepecify  alternate  labeling  and then use
193       restorecon to put the labels on disk.
194
195       semanage  fcontext  -a  -t   varnishd_var_run_t   '/srv/myvarnishd_con‐
196       tent(/.*)?'
197       restorecon -R -v /srv/myvarnishd_content
198
199       Note:  SELinux  often  uses  regular expressions to specify labels that
200       match multiple files.
201
202       The following file types are defined for varnishd:
203
204
205
206       varnishd_etc_t
207
208       - Set files with the varnishd_etc_t type, if you want to store varnishd
209       files in the /etc directories.
210
211
212
213       varnishd_exec_t
214
215       - Set files with the varnishd_exec_t type, if you want to transition an
216       executable to the varnishd_t domain.
217
218
219
220       varnishd_initrc_exec_t
221
222       - Set files with the varnishd_initrc_exec_t type, if you want to  tran‐
223       sition an executable to the varnishd_initrc_t domain.
224
225
226
227       varnishd_tmp_t
228
229       - Set files with the varnishd_tmp_t type, if you want to store varnishd
230       temporary files in the /tmp directories.
231
232
233
234       varnishd_var_lib_t
235
236       - Set files with the varnishd_var_lib_t type, if you want to store  the
237       varnishd files under the /var/lib directory.
238
239
240
241       varnishd_var_run_t
242
243       -  Set files with the varnishd_var_run_t type, if you want to store the
244       varnishd files under the /run or /var/run directory.
245
246
247
248       Note: File context can be temporarily modified with the chcon  command.
249       If  you want to permanently change the file context you need to use the
250       semanage fcontext command.  This will modify the SELinux labeling data‐
251       base.  You will need to use restorecon to apply the labels.
252
253

COMMANDS

255       semanage  fcontext  can also be used to manipulate default file context
256       mappings.
257
258       semanage permissive can also be used to manipulate  whether  or  not  a
259       process type is permissive.
260
261       semanage  module can also be used to enable/disable/install/remove pol‐
262       icy modules.
263
264       semanage port can also be used to manipulate the port definitions
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.
