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 all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type nut_upsdrvctl_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

121 SELinux requires files to have an extended attribute to define the file
122 type.
123 You can see the context of a file using the -Z option to ls
125 Policy governs the access confined processes have to these files.
127 SELinux nut_upsdrvctl policy is very flexible allowing users to setup
128 their nut_upsdrvctl processes in as secure a method as possible.
129 STANDARD FILE CONTEXT
131 SELinux defines the file context types for the nut_upsdrvctl, if you
133 wanted to store files with these types in a diffent paths, you need to
134 execute the semanage command to sepecify alternate labeling and then
135 use restorecon to put the labels on disk.
136 semanage fcontext -a -t nut_upsdrvctl_tmp_t '/srv/mynut_upsdrvctl_con‐
138 tent(/.*)?'
139 restorecon -R -v /srv/mynut_upsdrvctl_content
140 Note: SELinux often uses regular expressions to specify labels that
142 match multiple files.
143 The following file types are defined for nut_upsdrvctl:
145 nut_upsdrvctl_exec_t
149 - Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
151 tion an executable to the nut_upsdrvctl_t domain.
152 Paths:
155 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
156 nut_upsdrvctl_tmp_t
159 - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
161 upsdrvctl temporary files in the /tmp directories.
162 Note: File context can be temporarily modified with the chcon command.
166 If you want to permanently change the file context you need to use the
167 semanage fcontext command. This will modify the SELinux labeling data‐
168 base. You will need to use restorecon to apply the labels.
169
172 semanage fcontext can also be used to manipulate default file context
173 mappings.
174 semanage permissive can also be used to manipulate whether or not a
176 process type is permissive.
177 semanage module can also be used to enable/disable/install/remove pol‐
179 icy modules.
180 semanage boolean can also be used to manipulate the booleans
182 system-config-selinux is a GUI tool available to customize SELinux pol‐
185 icy settings.
