6 nut_upsdrvctl_selinux - Security Enhanced Linux Policy for the nut_ups‐
7 drvctl processes
8
10 Security-Enhanced Linux secures the nut_upsdrvctl processes via flexi‐
11 ble mandatory access control.
12 The nut_upsdrvctl processes execute with the nut_upsdrvctl_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep nut_upsdrvctl_t
20
24 The nut_upsdrvctl_t SELinux type can be entered via the nut_ups‐
25 drvctl_exec_t file type.
26 The default entrypoint paths for the nut_upsdrvctl_t domain are the
28 following:
29 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
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 nut_upsdrvctl policy is very flexible allowing users to setup their
40 nut_upsdrvctl processes in as secure a method as possible.
41 The following process types are defined for nut_upsdrvctl:
43 nut_upsdrvctl_t
45 Note: semanage permissive -a nut_upsdrvctl_t can be used to make the
47 process type nut_upsdrvctl_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 nut_upsdrvctl policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run nut_upsdrvctl with the
56 tightest access 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 domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 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 setsebool -P nscd_use_shm 1

97 The SELinux process type nut_upsdrvctl_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 Policy governs the access confined processes have to these files.
152 SELinux nut_upsdrvctl policy is very flexible allowing users to setup
153 their nut_upsdrvctl processes in as secure a method as possible.
154 STANDARD FILE CONTEXT
156 SELinux defines the file context types for the nut_upsdrvctl, if you
158 wanted to store files with these types in a diffent paths, you need to
159 execute the semanage command to sepecify alternate labeling and then
160 use restorecon to put the labels on disk.
161 semanage fcontext -a -t nut_upsdrvctl_tmp_t '/srv/mynut_upsdrvctl_con‐
163 tent(/.*)?'
164 restorecon -R -v /srv/mynut_upsdrvctl_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for nut_upsdrvctl:
170 nut_upsdrvctl_exec_t
174 - Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
176 tion an executable to the nut_upsdrvctl_t domain.
177 Paths:
180 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
181 nut_upsdrvctl_tmp_t
184 - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
186 upsdrvctl temporary files in the /tmp directories.
187 Note: File context can be temporarily modified with the chcon command.
191 If you want to permanently change the file context you need to use the
192 semanage fcontext command. This will modify the SELinux labeling data‐
193 base. You will need to use restorecon to apply the labels.
194
197 semanage fcontext can also be used to manipulate default file context
198 mappings.
199 semanage permissive can also be used to manipulate whether or not a
201 process type is permissive.
202 semanage module can also be used to enable/disable/install/remove pol‐
204 icy modules.
205 semanage boolean can also be used to manipulate the booleans
207 system-config-selinux is a GUI tool available to customize SELinux pol‐
210 icy settings.
