NAME

6       authconfig_selinux  - Security Enhanced Linux Policy for the authconfig
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  authconfig_t SELinux type can be entered via the authconfig_exec_t
25       file type.
26
27       The default entrypoint paths for the authconfig_t domain are  the  fol‐
28       lowing:
29
30       /usr/share/authconfig/authconfig.py
31

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

105       The SELinux process type authconfig_t can manage files labeled with the
106       following file types.  The paths listed are the default paths for these
107       file types.  Note the processes UID still need to have DAC permissions.
108
109       file_type
110
111            all files on the system
112
113

FILE CONTEXTS

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy  governs  the  access  confined  processes  have to these files.
121       SELinux authconfig policy is very  flexible  allowing  users  to  setup
122       their authconfig processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux  defines  the  file  context  types  for the authconfig, if you
127       wanted to store files with these types in a diffent paths, you need  to
128       execute  the  semanage  command to sepecify alternate labeling and then
129       use restorecon to put the labels on disk.
130
131       semanage fcontext -a  -t  authconfig_var_lib_t  '/srv/myauthconfig_con‐
132       tent(/.*)?'
133       restorecon -R -v /srv/myauthconfig_content
134
135       Note:  SELinux  often  uses  regular expressions to specify labels that
136       match multiple files.
137
138       The following file types are defined for authconfig:
139
140
141
142       authconfig_exec_t
143
144       - Set files with the authconfig_exec_t type, if you want to  transition
145       an executable to the authconfig_t domain.
146
147
148
149       authconfig_var_lib_t
150
151       -  Set  files  with the authconfig_var_lib_t type, if you want to store
152       the authconfig files under the /var/lib directory.
153
154
155
156       Note: File context can be temporarily modified with the chcon  command.
157       If  you want to permanently change the file context you need to use the
158       semanage fcontext command.  This will modify the SELinux labeling data‐
159       base.  You will need to use restorecon to apply the labels.
160
161

COMMANDS

163       semanage  fcontext  can also be used to manipulate default file context
164       mappings.
165
166       semanage permissive can also be used to manipulate  whether  or  not  a
167       process type is permissive.
168
169       semanage  module can also be used to enable/disable/install/remove pol‐
170       icy modules.
171
172       semanage boolean can also be used to manipulate the booleans
173
174
175       system-config-selinux is a GUI tool available to customize SELinux pol‐
176       icy settings.
