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 all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow sysadm to debug or ptrace all processes, you must
76 turn on the allow_ptrace boolean. Disabled by default.
77 setsebool -P allow_ptrace 1
79 If you want to allow all domains to have the kernel load modules, you
83 must turn on the domain_kernel_load_modules boolean. Disabled by
84 default.
85 setsebool -P domain_kernel_load_modules 1
87 If you want to allow all domains to execute in fips_mode, you must turn
91 on the fips_mode boolean. Enabled by default.
92 setsebool -P fips_mode 1
94 If you want to enable reading of urandom for all domains, you must turn
98 on the global_ssp boolean. Disabled by default.
99 setsebool -P global_ssp 1

105 The SELinux process type updfstab_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.

158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux updfstab policy is very flexible allowing users to setup their
165 updfstab processes in as secure a method as possible.
166 The following file types are defined for updfstab:
168 updfstab_exec_t
172 - Set files with the updfstab_exec_t type, if you want to transition an
174 executable to the updfstab_t domain.
175 Paths:
178 /usr/sbin/updfstab, /usr/sbin/fstab-sync
179 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196 semanage boolean can also be used to manipulate the booleans
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
