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
56       access 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 allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73
74
75
76       If you want to control the ability to mmap a low area  of  the  address
77       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
78       the mmap_low_allowed boolean. Disabled by default.
79
80       setsebool -P mmap_low_allowed 1
81
82
83
84       If you want to disable kernel module loading,  you  must  turn  on  the
85       secure_mode_insmod boolean. Enabled by default.
86
87       setsebool -P secure_mode_insmod 1
88
89
90
91       If  you  want to allow unconfined executables to make their heap memory
92       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
93       badly  coded  executable, but could indicate an attack. This executable
94       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
95       uxuser_execheap boolean. Disabled by default.
96
97       setsebool -P selinuxuser_execheap 1
98
99
100
101       If  you  want  to allow unconfined executables to make their stack exe‐
102       cutable.  This should never, ever be necessary.  Probably  indicates  a
103       badly  coded  executable, but could indicate an attack. This executable
104       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
105       stack boolean. Disabled by default.
106
107       setsebool -P selinuxuser_execstack 1

MANAGED FILES

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

FILE CONTEXTS

122       SELinux requires files to have an extended attribute to define the file
123       type.
124
125       You can see the context of a file using the -Z option to ls
126
127       Policy governs the access  confined  processes  have  to  these  files.
128       SELinux  authconfig  policy  is  very  flexible allowing users to setup
129       their authconfig processes in as secure a method as possible.
130
131       STANDARD FILE CONTEXT
132
133       SELinux defines the file context  types  for  the  authconfig,  if  you
134       wanted  to store files with these types in a diffent paths, you need to
135       execute the semanage command to sepecify alternate  labeling  and  then
136       use restorecon to put the labels on disk.
137
138       semanage  fcontext  -a  -t authconfig_var_lib_t '/srv/myauthconfig_con‐
139       tent(/.*)?'
140       restorecon -R -v /srv/myauthconfig_content
141
142       Note: SELinux often uses regular expressions  to  specify  labels  that
143       match multiple files.
144
145       The following file types are defined for authconfig:
146
147
148
149       authconfig_exec_t
150
151       -  Set files with the authconfig_exec_t type, if you want to transition
152       an executable to the authconfig_t domain.
153
154
155
156       authconfig_var_lib_t
157
158       - Set files with the authconfig_var_lib_t type, if you  want  to  store
159       the authconfig files under the /var/lib directory.
160
161
162
163       Note:  File context can be temporarily modified with the chcon command.
164       If you want to permanently change the file context you need to use  the
165       semanage fcontext command.  This will modify the SELinux labeling data‐
166       base.  You will need to use restorecon to apply the labels.
167
168

COMMANDS

170       semanage fcontext can also be used to manipulate default  file  context
171       mappings.
172
173       semanage  permissive  can  also  be used to manipulate whether or not a
174       process type is permissive.
175
176       semanage module can also be used to enable/disable/install/remove  pol‐
177       icy modules.
178
179       semanage boolean can also be used to manipulate the booleans
180
181
182       system-config-selinux is a GUI tool available to customize SELinux pol‐
183       icy settings.
