NAME

6       updfstab_selinux - Security Enhanced Linux Policy for the updfstab pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The updfstab_t SELinux type can be entered via the updfstab_exec_t file
25       type.
26
27       The default entrypoint paths for the updfstab_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/updfstab, /usr/sbin/fstab-sync
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       updfstab policy is very flexible allowing users to setup their updfstab
40       processes in as secure a method as possible.
41
42       The following process types are defined for updfstab:
43
44       updfstab_t
45
46       Note: semanage permissive -a updfstab_t can be used to make the process
47       type  updfstab_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  updf‐
54       stab policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run updfstab with the tightest access
56       possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Enabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

97       The SELinux process type updfstab_t can manage files labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.
100
101       etc_t
102
103            /etc/.*
104            /usr/etc(/.*)?

FILE CONTEXTS

141       SELinux requires files to have an extended attribute to define the file
142       type.
143
144       You can see the context of a file using the -Z option to ls
145
146       Policy  governs  the  access  confined  processes  have to these files.
147       SELinux updfstab policy is very flexible allowing users to setup  their
148       updfstab processes in as secure a method as possible.
149
150       The following file types are defined for updfstab:
151
152
153
154       updfstab_exec_t
155
156       - Set files with the updfstab_exec_t type, if you want to transition an
157       executable to the updfstab_t domain.
158
159
160       Paths:
161            /usr/sbin/updfstab, /usr/sbin/fstab-sync
162
163
164       Note: File context can be temporarily modified with the chcon  command.
165       If  you want to permanently change the file context you need to use the
166       semanage fcontext command.  This will modify the SELinux labeling data‐
167       base.  You will need to use restorecon to apply the labels.
168
169

COMMANDS

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