6 updfstab_selinux - Security Enhanced Linux Policy for the updfstab pro‐
7 cesses
8
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
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
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
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. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
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.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141
142 You can see the context of a file using the -Z option to ls
143
144 Policy governs the access confined processes have to these files.
145 SELinux updfstab policy is very flexible allowing users to setup their
146 updfstab processes in as secure a method as possible.
147
148 The following file types are defined for updfstab:
149
150
151
152 updfstab_exec_t
153
154 - Set files with the updfstab_exec_t type, if you want to transition an
155 executable to the updfstab_t domain.
156
157
158 Paths:
159 /usr/sbin/updfstab, /usr/sbin/fstab-sync
160
161
162 Note: File context can be temporarily modified with the chcon command.
163 If you want to permanently change the file context you need to use the
164 semanage fcontext command. This will modify the SELinux labeling data‐
165 base. You will need to use restorecon to apply the labels.
166
167
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171
172 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174
175 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177
178 semanage boolean can also be used to manipulate the booleans
179
180
181 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
