NAME

6       keepalived_unconfined_script_selinux  -  Security Enhanced Linux Policy
7       for the keepalived_unconfined_script processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the  keepalived_unconfined_script  pro‐
11       cesses via flexible mandatory access control.
12
13       The    keepalived_unconfined_script    processes   execute   with   the
14       keepalived_unconfined_script_t SELinux type. You can check if you  have
15       these  processes running by executing the ps command with the -Z quali‐
16       fier.
17
18       For example:
19
20       ps -eZ | grep keepalived_unconfined_script_t
21
22
23

ENTRYPOINTS

25       The keepalived_unconfined_script_t SELinux type can be entered via  the
26       keepalived_unconfined_script_exec_t file type.
27
28       The  default  entrypoint  paths  for the keepalived_unconfined_script_t
29       domain are the following:
30
31       /usr/libexec/keepalived(/.*)?
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       keepalived_unconfined_script policy is very flexible allowing users  to
41       setup  their  keepalived_unconfined_script  processes  in  as  secure a
42       method as possible.
43
44       The  following  process  types  are   defined   for   keepalived_uncon‐
45       fined_script:
46
47       keepalived_unconfined_script_t
48
49       Note: semanage permissive -a keepalived_unconfined_script_t can be used
50       to make the  process  type  keepalived_unconfined_script_t  permissive.
51       SELinux  does  not deny access to permissive process types, but the AVC
52       (SELinux denials) messages are still generated.
53
54

BOOLEANS

56       SELinux  policy  is  customizable  based  on  least  access   required.
57       keepalived_unconfined_script  policy is extremely flexible and has sev‐
58       eral  booleans  that  allow  you  to  manipulate  the  policy  and  run
59       keepalived_unconfined_script with the tightest access possible.
60
61
62
63       If you want to deny user domains applications to map a memory region as
64       both executable and writable, this  is  dangerous  and  the  executable
65       should be reported in bugzilla, you must turn on the deny_execmem bool‐
66       ean. Enabled by default.
67
68       setsebool -P deny_execmem 1
69
70
71
72       If you want to allow all domains to execute in fips_mode, you must turn
73       on the fips_mode boolean. Enabled by default.
74
75       setsebool -P fips_mode 1
76
77
78
79       If  you  want  to control the ability to mmap a low area of the address
80       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
81       the mmap_low_allowed boolean. Disabled by default.
82
83       setsebool -P mmap_low_allowed 1
84
85
86
87       If  you  want  to  disable  kernel module loading, you must turn on the
88       secure_mode_insmod boolean. Enabled by default.
89
90       setsebool -P secure_mode_insmod 1
91
92
93
94       If you want to allow unconfined executables to make their  heap  memory
95       executable.   Doing  this  is  a  really bad idea. Probably indicates a
96       badly coded executable, but could indicate an attack.  This  executable
97       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
98       uxuser_execheap boolean. Disabled by default.
99
100       setsebool -P selinuxuser_execheap 1
101
102
103
104       If you want to allow unconfined executables to make  their  stack  exe‐
105       cutable.   This  should  never, ever be necessary. Probably indicates a
106       badly coded executable, but could indicate an attack.  This  executable
107       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
108       stack boolean. Disabled by default.
109
110       setsebool -P selinuxuser_execstack 1

MANAGED FILES

115       The SELinux  process  type  keepalived_unconfined_script_t  can  manage
116       files  labeled with the following file types.  The paths listed are the
117       default paths for these file types.  Note the processes UID still  need
118       to have DAC permissions.
119
120       file_type
121
122            all files on the system
123
124

FILE CONTEXTS

126       SELinux requires files to have an extended attribute to define the file
127       type.
128
129       You can see the context of a file using the -Z option to ls
130
131       Policy governs the access  confined  processes  have  to  these  files.
132       SELinux  keepalived_unconfined_script  policy is very flexible allowing
133       users to  setup  their  keepalived_unconfined_script  processes  in  as
134       secure a method as possible.
135
136       The following file types are defined for keepalived_unconfined_script:
137
138
139
140       keepalived_unconfined_script_exec_t
141
142       -  Set  files with the keepalived_unconfined_script_exec_t type, if you
143       want to transition an executable to the  keepalived_unconfined_script_t
144       domain.
145
146
147
148       Note:  File context can be temporarily modified with the chcon command.
149       If you want to permanently change the file context you need to use  the
150       semanage fcontext command.  This will modify the SELinux labeling data‐
151       base.  You will need to use restorecon to apply the labels.
152
153

COMMANDS

155       semanage fcontext can also be used to manipulate default  file  context
156       mappings.
157
158       semanage  permissive  can  also  be used to manipulate whether or not a
159       process type is permissive.
160
161       semanage module can also be used to enable/disable/install/remove  pol‐
162       icy modules.
163
164       semanage boolean can also be used to manipulate the booleans
165
166
167       system-config-selinux is a GUI tool available to customize SELinux pol‐
168       icy settings.
