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

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

MANAGED FILES

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

FILE CONTEXTS

117       SELinux requires files to have an extended attribute to define the file
118       type.
119
120       You can see the context of a file using the -Z option to ls
121
122       Policy  governs  the  access  confined  processes  have to these files.
123       SELinux sbd policy is very flexible allowing users to setup  their  sbd
124       processes in as secure a method as possible.
125
126       STANDARD FILE CONTEXT
127
128       SELinux  defines  the  file context types for the sbd, if you wanted to
129       store files with these types in a diffent paths, you  need  to  execute
130       the  semanage  command  to  sepecify  alternate  labeling  and then use
131       restorecon to put the labels on disk.
132
133       semanage fcontext -a -t sbd_tmpfs_t '/srv/mysbd_content(/.*)?'
134       restorecon -R -v /srv/mysbd_content
135
136       Note: SELinux often uses regular expressions  to  specify  labels  that
137       match multiple files.
138
139       The following file types are defined for sbd:
140
141
142
143       sbd_exec_t
144
145       - Set files with the sbd_exec_t type, if you want to transition an exe‐
146       cutable to the sbd_t domain.
147
148
149
150       sbd_tmpfs_t
151
152       - Set files with the sbd_tmpfs_t type, if you want to store  sbd  files
153       on a tmpfs file system.
154
155
156
157       sbd_unit_file_t
158
159       -  Set  files  with  the sbd_unit_file_t type, if you want to treat the
160       files as sbd unit content.
161
162
163       Paths:
164            /usr/lib/systemd/system/sbd.service,         /usr/lib/systemd/sys‐
165            tem/sbd_remote.service
166
167
168       sbd_var_run_t
169
170       -  Set  files with the sbd_var_run_t type, if you want to store the sbd
171       files under the /run or /var/run directory.
172
173
174
175       Note: File context can be temporarily modified with the chcon  command.
176       If  you want to permanently change the file context you need to use the
177       semanage fcontext command.  This will modify the SELinux labeling data‐
178       base.  You will need to use restorecon to apply the labels.
179
180

COMMANDS

182       semanage  fcontext  can also be used to manipulate default file context
183       mappings.
184
185       semanage permissive can also be used to manipulate  whether  or  not  a
186       process type is permissive.
187
188       semanage  module can also be used to enable/disable/install/remove pol‐
189       icy modules.
190
191       semanage boolean can also be used to manipulate the booleans
192
193
194       system-config-selinux is a GUI tool available to customize SELinux pol‐
195       icy settings.
