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 allow all domains to execute in fips_mode, you must turn
56 on the fips_mode boolean. Enabled by default.
57 setsebool -P fips_mode 1
59 If you want to allow confined applications to use nscd shared memory,
63 you must turn on the nscd_use_shm boolean. Disabled by default.
64 setsebool -P nscd_use_shm 1
66
70 SELinux defines port types to represent TCP and UDP ports.
71 You can see the types associated with a port by using the following
73 command:
74 semanage port -l
76 Policy governs the access confined processes have to these ports.
79 SELinux rkt policy is very flexible allowing users to setup their rkt
80 processes in as secure a method as possible.
81 The following port types are defined for rkt:
83 rkt_port_t
86 Default Defined Ports:
90 tcp 18112
91
93 The SELinux process type rkt_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux rkt policy is very flexible allowing users to setup their rkt
145 processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the rkt, if you wanted to
150 store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use
152 restorecon to put the labels on disk.
153 semanage fcontext -a -t rkt_unit_file_t '/srv/myrkt_content(/.*)?'
155 restorecon -R -v /srv/myrkt_content
156 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159 The following file types are defined for rkt:
161 rkt_exec_t
165 - Set files with the rkt_exec_t type, if you want to transition an exe‐
167 cutable to the rkt_t domain.
168 rkt_unit_file_t
172 - Set files with the rkt_unit_file_t type, if you want to treat the
174 files as rkt unit content.
175 Paths:
178 /usr/lib/systemd/system/rkt-gc.timer, /usr/lib/systemd/system/rkt-
179 gc.service, /usr/lib/systemd/system/rkt-metadata.socket,
180 /usr/lib/systemd/system/rkt-metadata.service
181 rkt_var_lib_t
184 - Set files with the rkt_var_lib_t type, if you want to store the rkt
186 files under the /var/lib directory.
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 port can also be used to manipulate the port definitions
207 semanage boolean can also be used to manipulate the booleans
209 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
