NAME

6       sbd_selinux - Security Enhanced Linux Policy for the sbd processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the sbd processes via flexible manda‐
10       tory access control.
11
12       The sbd processes execute with the sbd_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 sbd_t
19

21

ENTRYPOINTS

23       The sbd_t SELinux type can be entered via the sbd_exec_t file type.
24
25       The default entrypoint paths for the sbd_t domain are the following:
26
27       /usr/sbin/sbd
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       sbd policy is very flexible allowing users to setup their sbd processes
37       in as secure a method as possible.
38
39       The following process types are defined for sbd:
40
41       sbd_t
42
43       Note: semanage permissive -a sbd_t can be used to make the process type
44       sbd_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.  sbd
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run sbd 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 system to run with  NIS,  you  must  turn  on  the
63       nis_enabled boolean. Disabled by default.
64
65       setsebool -P nis_enabled 1
66

MANAGED FILES

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

FILE CONTEXTS

125       SELinux requires files to have an extended attribute to define the file
126       type.
127
128       You can see the context of a file using the -Z option to ls
129
130       Policy governs the access  confined  processes  have  to  these  files.
131       SELinux  sbd  policy is very flexible allowing users to setup their sbd
132       processes in as secure a method as possible.
133
134       STANDARD FILE CONTEXT
135
136       SELinux defines the file context types for the sbd, if  you  wanted  to
137       store  files  with  these types in a diffent paths, you need to execute
138       the semanage command  to  sepecify  alternate  labeling  and  then  use
139       restorecon to put the labels on disk.
140
141       semanage fcontext -a -t sbd_tmpfs_t '/srv/mysbd_content(/.*)?'
142       restorecon -R -v /srv/mysbd_content
143
144       Note:  SELinux  often  uses  regular expressions to specify labels that
145       match multiple files.
146
147       The following file types are defined for sbd:
148
149
150
151       sbd_exec_t
152
153       - Set files with the sbd_exec_t type, if you want to transition an exe‐
154       cutable to the sbd_t domain.
155
156
157
158       sbd_tmpfs_t
159
160       -  Set  files with the sbd_tmpfs_t type, if you want to store sbd files
161       on a tmpfs file system.
162
163
164
165       sbd_unit_file_t
166
167       - Set files with the sbd_unit_file_t type, if you  want  to  treat  the
168       files as sbd unit content.
169
170
171       Paths:
172            /usr/lib/systemd/system/sbd.service,         /usr/lib/systemd/sys‐
173            tem/sbd_remote.service
174
175
176       sbd_var_run_t
177
178       - Set files with the sbd_var_run_t type, if you want to store  the  sbd
179       files under the /run or /var/run directory.
180
181
182
183       Note:  File context can be temporarily modified with the chcon command.
184       If you want to permanently change the file context you need to use  the
185       semanage fcontext command.  This will modify the SELinux labeling data‐
186       base.  You will need to use restorecon to apply the labels.
187
188

COMMANDS

190       semanage fcontext can also be used to manipulate default  file  context
191       mappings.
192
193       semanage  permissive  can  also  be used to manipulate whether or not a
194       process type is permissive.
195
196       semanage module can also be used to enable/disable/install/remove  pol‐
197       icy modules.
198
199       semanage boolean can also be used to manipulate the booleans
200
201
202       system-config-selinux is a GUI tool available to customize SELinux pol‐
203       icy settings.
