NAME

6       publicfile_selinux  - Security Enhanced Linux Policy for the publicfile
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  publicfile_t SELinux type can be entered via the publicfile_exec_t
25       file type.
26
27       The default entrypoint paths for the publicfile_t domain are  the  fol‐
28       lowing:
29
30       /usr/bin/ftpd, /usr/bin/httpd
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       publicfile  policy  is very flexible allowing users to setup their pub‐
40       licfile processes in as secure a method as possible.
41
42       The following process types are defined for publicfile:
43
44       publicfile_t
45
46       Note: semanage permissive -a publicfile_t  can  be  used  to  make  the
47       process  type  publicfile_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.  public‐
54       file policy is extremely flexible and has several booleans  that  allow
55       you  to  manipulate  the  policy  and  run publicfile with the tightest
56       access possible.
57
58
59
60       If you want to allow all daemons to write corefiles to /, you must turn
61       on the daemons_dump_core boolean. Disabled by default.

95
96       If you want to allow any process  to  mmap  any  file  on  system  with

MANAGED FILES

142       The SELinux process type publicfile_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.
145
146       cluster_conf_t

FILE CONTEXTS

183       SELinux requires files to have an extended attribute to define the file
184       type.
185
186       You can see the context of a file using the -Z option to ls
187
188       Policy governs the access  confined  processes  have  to  these  files.
189       SELinux  publicfile  policy  is  very  flexible allowing users to setup
190       their publicfile processes in as secure a method as possible.
191
192       STANDARD FILE CONTEXT
193
194       SELinux defines the file context  types  for  the  publicfile,  if  you
195       wanted  to store files with these types in a diffent paths, you need to
196       execute the semanage command to sepecify alternate  labeling  and  then
197       use restorecon to put the labels on disk.
198
199       semanage  fcontext  -a  -t publicfile_content_t '/srv/mypublicfile_con‐
200       tent(/.*)?'
201       restorecon -R -v /srv/mypublicfile_content
202
203       Note: SELinux often uses regular expressions  to  specify  labels  that
204       match multiple files.
205
206       The following file types are defined for publicfile:
207
208
209
210       publicfile_content_t
211
212       -  Set  files  with the publicfile_content_t type, if you want to treat
213       the files as publicfile content.
214
215
216
217       publicfile_exec_t
218
219       - Set files with the publicfile_exec_t type, if you want to  transition
220       an executable to the publicfile_t domain.
221
222
223       Paths:
224            /usr/bin/ftpd, /usr/bin/httpd
225
226
227       Note:  File context can be temporarily modified with the chcon command.
228       If you want to permanently change the file context you need to use  the
229       semanage fcontext command.  This will modify the SELinux labeling data‐
230       base.  You will need to use restorecon to apply the labels.
231
232

COMMANDS

234       semanage fcontext can also be used to manipulate default  file  context
235       mappings.
236
237       semanage  permissive  can  also  be used to manipulate whether or not a
238       process type is permissive.
239
240       semanage module can also be used to enable/disable/install/remove  pol‐
241       icy modules.
242
243       semanage boolean can also be used to manipulate the booleans
244
245
246       system-config-selinux is a GUI tool available to customize SELinux pol‐
247       icy settings.
