6 nut_upsd_selinux - Security Enhanced Linux Policy for the nut_upsd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the nut_upsd processes via flexible
11 mandatory access control.
12 The nut_upsd processes execute with the nut_upsd_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 nut_upsd_t
20
24 The nut_upsd_t SELinux type can be entered via the nut_upsd_exec_t file
25 type.
26 The default entrypoint paths for the nut_upsd_t domain are the follow‐
28 ing:
29 /usr/sbin/upsd
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_upsd policy is very flexible allowing users to setup their nut_upsd
40 processes in as secure a method as possible.
41 The following process types are defined for nut_upsd:
43 nut_upsd_t, nut_upsdrvctl_t
45 Note: semanage permissive -a nut_upsd_t can be used to make the process
47 type nut_upsd_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.
54 nut_upsd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run nut_upsd with the tightest
56 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. Enabled 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
93
97 The SELinux process type nut_upsd_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.

145 SELinux requires files to have an extended attribute to define the file
146 type.
147 You can see the context of a file using the -Z option to ls
149 Policy governs the access confined processes have to these files.
151 SELinux nut_upsd policy is very flexible allowing users to setup their
152 nut_upsd processes in as secure a method as possible.
153 STANDARD FILE CONTEXT
155 SELinux defines the file context types for the nut_upsd, if you wanted
157 to store files with these types in a diffent paths, you need to execute
158 the semanage command to sepecify alternate labeling and then use
159 restorecon to put the labels on disk.
160 semanage fcontext -a -t nut_upsdrvctl_tmp_t '/srv/mynut_upsd_con‐
162 tent(/.*)?'
163 restorecon -R -v /srv/mynut_upsd_content
164 Note: SELinux often uses regular expressions to specify labels that
166 match multiple files.
167 The following file types are defined for nut_upsd:
169 nut_upsd_exec_t
173 - Set files with the nut_upsd_exec_t type, if you want to transition an
175 executable to the nut_upsd_t domain.
176 nut_upsd_tmp_t
180 - Set files with the nut_upsd_tmp_t type, if you want to store nut upsd
182 temporary files in the /tmp directories.
183 nut_upsdrvctl_exec_t
187 - Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
189 tion an executable to the nut_upsdrvctl_t domain.
190 Paths:
193 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
194 nut_upsdrvctl_tmp_t
197 - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
199 upsdrvctl temporary files in the /tmp directories.
200 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
