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. Enabled 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.

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