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 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 For example:
18 ps -eZ | grep updfstab_t
20
24 The updfstab_t SELinux type can be entered via the updfstab_exec_t file
25 type.
26 The default entrypoint paths for the updfstab_t domain are the follow‐
28 ing:
29 /usr/sbin/updfstab, /usr/sbin/fstab-sync
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for updfstab:
43 updfstab_t
45 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
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 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all daemons the ability to read/write terminals,
69 you must turn on the daemons_use_tty boolean. Disabled by default.
70 setsebool -P daemons_use_tty 1
72 If you want to deny any process from ptracing or debugging any other
76 processes, you must turn on the deny_ptrace boolean. Enabled by
77 default.
78 setsebool -P deny_ptrace 1
80 If you want to allow any process to mmap any file on system with
84 attribute file_type, you must turn on the domain_can_mmap_files bool‐
85 ean. Enabled by default.
86 setsebool -P domain_can_mmap_files 1
88 If you want to allow all domains write to kmsg_device, while kernel is
92 executed with systemd.log_target=kmsg parameter, you must turn on the
93 domain_can_write_kmsg boolean. Disabled by default.
94 setsebool -P domain_can_write_kmsg 1
96 If you want to allow all domains to use other domains file descriptors,
100 you must turn on the domain_fd_use boolean. Enabled by default.
101 setsebool -P domain_fd_use 1
103 If you want to allow all domains to have the kernel load modules, you
107 must turn on the domain_kernel_load_modules boolean. Disabled by
108 default.
109 setsebool -P domain_kernel_load_modules 1
111 If you want to allow all domains to execute in fips_mode, you must turn
115 on the fips_mode boolean. Enabled by default.
116 setsebool -P fips_mode 1
118 If you want to enable reading of urandom for all domains, you must turn
122 on the global_ssp boolean. Disabled by default.
123 setsebool -P global_ssp 1
125 If you want to allow confined applications to run with kerberos, you
129 must turn on the kerberos_enabled boolean. Enabled by default.
130 setsebool -P kerberos_enabled 1
132 If you want to allow system to run with NIS, you must turn on the
136 nis_enabled boolean. Disabled by default.
137 setsebool -P nis_enabled 1
139 If you want to allow confined applications to use nscd shared memory,
143 you must turn on the nscd_use_shm boolean. Disabled by default.
144 setsebool -P nscd_use_shm 1
146
150 The SELinux process type updfstab_t can manage files labeled with the
151 following file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.

191 SELinux requires files to have an extended attribute to define the file
192 type.
193 You can see the context of a file using the -Z option to ls
195 Policy governs the access confined processes have to these files.
197 SELinux updfstab policy is very flexible allowing users to setup their
198 updfstab processes in as secure a method as possible.
199 The following file types are defined for updfstab:
201 updfstab_exec_t
205 - Set files with the updfstab_exec_t type, if you want to transition an
207 executable to the updfstab_t domain.
208 Paths:
211 /usr/sbin/updfstab, /usr/sbin/fstab-sync
212 Note: File context can be temporarily modified with the chcon command.
215 If you want to permanently change the file context you need to use the
216 semanage fcontext command. This will modify the SELinux labeling data‐
217 base. You will need to use restorecon to apply the labels.
218
221 semanage fcontext can also be used to manipulate default file context
222 mappings.
223 semanage permissive can also be used to manipulate whether or not a
225 process type is permissive.
226 semanage module can also be used to enable/disable/install/remove pol‐
228 icy modules.
229 semanage boolean can also be used to manipulate the booleans
231 system-config-selinux is a GUI tool available to customize SELinux pol‐
234 icy settings.
