NAME

6       tzdata_selinux  -  Security  Enhanced  Linux Policy for the tzdata pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  tzdata_t  SELinux  type  can be entered via the tzdata_exec_t file
25       type.
26
27       The default entrypoint paths for the tzdata_t domain are the following:
28
29       /usr/sbin/tzdata-update
30

PROCESS TYPES

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

BOOLEANS

52       SELinux policy is customizable based on least access required.   tzdata
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run tzdata with the tightest access possible.

MANAGED FILES

131       The SELinux process type tzdata_t can manage  files  labeled  with  the
132       following file types.  The paths listed are the default paths for these
133       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

208       SELinux requires files to have an extended attribute to define the file
209       type.
210
211       You can see the context of a file using the -Z option to ls
212
213       Policy  governs  the  access  confined  processes  have to these files.
214       SELinux tzdata policy is very flexible allowing users  to  setup  their
215       tzdata processes in as secure a method as possible.
216
217       The following file types are defined for tzdata:
218
219
220
221       tzdata_exec_t
222
223       -  Set  files with the tzdata_exec_t type, if you want to transition an
224       executable to the tzdata_t domain.
225
226
227
228       Note: File context can be temporarily modified with the chcon  command.
229       If  you want to permanently change the file context you need to use the
230       semanage fcontext command.  This will modify the SELinux labeling data‐
231       base.  You will need to use restorecon to apply the labels.
232
233

COMMANDS

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