NAME

6       afs_selinux - Security Enhanced Linux Policy for the afs processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The afs_t SELinux type can be entered via the afs_exec_t file type.
24
25       The default entrypoint paths for the afs_t domain are the following:
26
27       /usr/sbin/afsd, /usr/vice/etc/afsd
28

PROCESS TYPES

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

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  afs
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run afs with the tightest access possible.
52
53
54
55       If you want to allow all domains to execute in fips_mode, you must turn
56       on the fips_mode boolean. Enabled by default.
57
58       setsebool -P fips_mode 1
59
60
61
62       If you want to allow confined applications to use nscd  shared  memory,
63       you must turn on the nscd_use_shm boolean. Enabled by default.
64
65       setsebool -P nscd_use_shm 1
66
67
68

PORT TYPES

70       SELinux defines port types to represent TCP and UDP ports.
71
72       You  can  see  the  types associated with a port by using the following
73       command:
74
75       semanage port -l
76
77
78       Policy governs the access  confined  processes  have  to  these  ports.
79       SELinux  afs  policy is very flexible allowing users to setup their afs
80       processes in as secure a method as possible.
81
82       The following port types are defined for afs:

MANAGED FILES

136       The SELinux process type afs_t can manage files labeled with  the  fol‐
137       lowing  file  types.   The paths listed are the default paths for these
138       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

181       SELinux requires files to have an extended attribute to define the file
182       type.
183
184       You can see the context of a file using the -Z option to ls
185
186       Policy  governs  the  access  confined  processes  have to these files.
187       SELinux afs policy is very flexible allowing users to setup  their  afs
188       processes in as secure a method as possible.
189
190       STANDARD FILE CONTEXT
191
192       SELinux  defines  the  file context types for the afs, if you wanted to
193       store files with these types in a diffent paths, you  need  to  execute
194       the  semanage  command  to sepecify alternate labeling and then use re‐
195       storecon to put the labels on disk.
196
197       semanage fcontext -a -t afs_vl_db_t '/srv/myafs_content(/.*)?'
198       restorecon -R -v /srv/myafs_content
199
200       Note: SELinux often uses regular expressions  to  specify  labels  that
201       match multiple files.

347       If  you want to permanently change the file context you need to use the
348       semanage fcontext command.  This will modify the SELinux labeling data‐
349       base.  You will need to use restorecon to apply the labels.
350
351

COMMANDS

353       semanage  fcontext  can also be used to manipulate default file context
354       mappings.
355
356       semanage permissive can also be used to manipulate  whether  or  not  a
357       process type is permissive.
358
359       semanage  module can also be used to enable/disable/install/remove pol‐
360       icy modules.
361
362       semanage port can also be used to manipulate the port definitions
363
364       semanage boolean can also be used to manipulate the booleans
365
366
367       system-config-selinux is a GUI tool available to customize SELinux pol‐
368       icy settings.
