6 rkt_selinux - Security Enhanced Linux Policy for the rkt processes
7
9 Security-Enhanced Linux secures the rkt processes via flexible manda‐
10 tory access control.
11 The rkt processes execute with the rkt_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15 For example:
17 ps -eZ | grep rkt_t
19
23 The rkt_t SELinux type can be entered via the rkt_exec_t file type.
24 The default entrypoint paths for the rkt_t domain are the following:
26 /usr/bin/rkt
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 rkt policy is very flexible allowing users to setup their rkt processes
37 in as secure a method as possible.
38 The following process types are defined for rkt:
40 rkt_t
42 Note: semanage permissive -a rkt_t can be used to make the process type
44 rkt_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
49 SELinux policy is customizable based on least access required. rkt
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run rkt with the tightest access possible.
52 If you want to dontaudit all daemons scheduling requests (setsched,
56 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
57 Enabled by default.
58 setsebool -P daemons_dontaudit_scheduling 1
60 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65 setsebool -P fips_mode 1
67 If you want to allow confined applications to use nscd shared memory,
71 you must turn on the nscd_use_shm boolean. Enabled by default.
72 setsebool -P nscd_use_shm 1
74
78 SELinux defines port types to represent TCP and UDP ports.
79 You can see the types associated with a port by using the following
81 command:
82 semanage port -l
84 Policy governs the access confined processes have to these ports.
87 SELinux rkt policy is very flexible allowing users to setup their rkt
88 processes in as secure a method as possible.
89 The following port types are defined for rkt:
91 rkt_port_t
94 Default Defined Ports:
98 tcp 18112
99
101 The SELinux process type rkt_t can manage files labeled with the fol‐
102 lowing file types. The paths listed are the default paths for these
103 file types. Note the processes UID still need to have DAC permissions.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149 You can see the context of a file using the -Z option to ls
151 Policy governs the access confined processes have to these files.
153 SELinux rkt policy is very flexible allowing users to setup their rkt
154 processes in as secure a method as possible.
155 STANDARD FILE CONTEXT
157 SELinux defines the file context types for the rkt, if you wanted to
159 store files with these types in a different paths, you need to execute
160 the semanage command to specify alternate labeling and then use re‐
161 storecon to put the labels on disk.
162 semanage fcontext -a -t rkt_exec_t '/srv/rkt/content(/.*)?'
164 restorecon -R -v /srv/myrkt_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for rkt:
170 rkt_exec_t
174 - Set files with the rkt_exec_t type, if you want to transition an exe‐
176 cutable to the rkt_t domain.
177 rkt_unit_file_t
181 - Set files with the rkt_unit_file_t type, if you want to treat the
183 files as rkt unit content.
184 Paths:
187 /usr/lib/systemd/system/rkt-gc.timer, /usr/lib/systemd/system/rkt-
188 gc.service, /usr/lib/systemd/system/rkt-metadata.socket,
189 /usr/lib/systemd/system/rkt-metadata.service
190 rkt_var_lib_t
193 - Set files with the rkt_var_lib_t type, if you want to store the rkt
195 files under the /var/lib directory.
196 Note: File context can be temporarily modified with the chcon command.
200 If you want to permanently change the file context you need to use the
201 semanage fcontext command. This will modify the SELinux labeling data‐
202 base. You will need to use restorecon to apply the labels.
203
206 semanage fcontext can also be used to manipulate default file context
207 mappings.
208 semanage permissive can also be used to manipulate whether or not a
210 process type is permissive.
211 semanage module can also be used to enable/disable/install/remove pol‐
213 icy modules.
214 semanage port can also be used to manipulate the port definitions
216 semanage boolean can also be used to manipulate the booleans
218 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
