NAME

neutron_selinux - Security Enhanced Linux Policy for the neutron processes

DESCRIPTION

Security-Enhanced Linux secures the neutron processes via flexible mandatory access control.

The neutron processes execute with the neutron_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep neutron_t

ENTRYPOINTS

The neutron_t SELinux type can be entered via the neutron_exec_t file type.

The default entrypoint paths for the neutron_t domain are the following:

/usr/bin/neutron-server, /usr/bin/quantum-server, /usr/bin/neutron-l3-agent, /usr/bin/neutron-rootwrap, /usr/bin/quantum-l3-agent, /usr/bin/neutron-ryu-agent, /usr/bin/quantum-ryu-agent, /usr/bin/neutron-dhcp-agent, /usr/bin/quantum-dhcp-agent, /usr/bin/neutron-lbaas-agent, /usr/bin/neutron-ovs-cleanup, /usr/bin/quantum-ovs-cleanup, /usr/bin/neutron-netns-cleanup, /usr/bin/neutron-metadata-agent, /usr/bin/neutron-linuxbridge-agent, /usr/bin/neutron-ns-metadata-proxy, /usr/bin/neutron-openvswitch-agent, /usr/bin/quantum-linuxbridge-agent, /usr/bin/quantum-openvswitch-agent

PROCESS TYPES

SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to ps

Policy governs the access confined processes have to files. SELinux neutron policy is very flexible allowing users to setup their neutron processes in as secure a method as possible.

The following process types are defined for neutron:

neutron_t

Note: semanage permissive -a neutron_t can be used to make the process type neutron_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

SELinux policy is customizable based on least access required. neutron policy is extremely flexible and has several booleans that allow you to manipulate the policy and run neutron with the tightest access possible.

If you want to determine whether neutron can connect to all TCP ports, you must turn on the neutron_can_network boolean. Disabled by default.

setsebool -P neutron_can_network 1

If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.

setsebool -P authlogin_nsswitch_use_ldap 1

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

setsebool -P kerberos_enabled 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

PORT TYPES

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

Policy governs the access confined processes have to these ports. SELinux neutron policy is very flexible allowing users to setup their neutron processes in as secure a method as possible.

The following port types are defined for neutron:





Default Defined Ports: tcp 8775,9696,9697

FILE CONTEXTS


SELinux requires files to have an extended attribute to define the
    file type.


You can see the context of a file using the -Z option to
    ls


Policy governs the access confined processes have to these files.
    SELinux neutron policy is very flexible allowing users to setup their
    neutron processes in as secure a method as possible.


STANDARD FILE CONTEXT


SELinux defines the file context types for the neutron, if you
    wanted to store files with these types in a diffent paths, you need to
    execute the semanage command to sepecify alternate labeling and then use
    restorecon to put the labels on disk.


semanage fcontext -a -t neutron_unit_file_t
    '/srv/myneutron_content(/.*)?'
  

  restorecon -R -v /srv/myneutron_content


Note: SELinux often uses regular expressions to specify labels
    that match multiple files.


The following file types are defined for neutron:






neutron_exec_t



- Set files with the neutron_exec_t type, if you want to
    transition an executable to the neutron_t domain.





  

  
/usr/bin/neutron-server, /usr/bin/quantum-server,
      /usr/bin/neutron-l3-agent, /usr/bin/neutron-rootwrap,
      /usr/bin/quantum-l3-agent, /usr/bin/neutron-ryu-agent,
      /usr/bin/quantum-ryu-agent, /usr/bin/neutron-dhcp-agent,
      /usr/bin/quantum-dhcp-agent, /usr/bin/neutron-lbaas-agent,
      /usr/bin/neutron-ovs-cleanup, /usr/bin/quantum-ovs-cleanup,
      /usr/bin/neutron-netns-cleanup, /usr/bin/neutron-metadata-agent,
      /usr/bin/neutron-linuxbridge-agent, /usr/bin/neutron-ns-metadata-proxy,
      /usr/bin/neutron-openvswitch-agent, /usr/bin/quantum-linuxbridge-agent,
      /usr/bin/quantum-openvswitch-agent
    

  




neutron_initrc_exec_t



- Set files with the neutron_initrc_exec_t type, if you want to
    transition an executable to the neutron_initrc_t domain.





  

  
/etc/rc.d/init.d/neutron.*, /etc/rc.d/init.d/quantum.*
    

  




neutron_log_t



- Set files with the neutron_log_t type, if you want to treat the
    data as neutron log data, usually stored under the /var/log directory.





  

  
/var/log/neutron(/.*)?, /var/log/quantum(/.*)?
    

  




neutron_tmp_t



- Set files with the neutron_tmp_t type, if you want to store
    neutron temporary files in the /tmp directories.






neutron_unit_file_t



- Set files with the neutron_unit_file_t type, if you want to
    treat the files as neutron unit content.





  

  
/usr/lib/systemd/system/neutron.*, /usr/lib/systemd/system/quantum.*
    

  




neutron_var_lib_t



- Set files with the neutron_var_lib_t type, if you want to store
    the neutron files under the /var/lib directory.





  

  
/var/lib/neutron(/.*)?, /var/lib/quantum(/.*)?
    

  




neutron_var_run_t



- Set files with the neutron_var_run_t type, if you want to store
    the neutron files under the /run or /var/run directory.





  

  
/var/run/neutron(/.*)?, /var/run/quantum(/.*)?
    

  




Note: File context can be temporarily modified with the chcon
    command. If you want to permanently change the file context you need to use
    the semanage fcontext command. This will modify the SELinux labeling
    database. You will need to use restorecon to apply the labels.








COMMANDS


semanage fcontext can also be used to manipulate default
    file context mappings.


semanage permissive can also be used to manipulate whether
    or not a process type is permissive.


semanage module can also be used to
    enable/disable/install/remove policy modules.


semanage port can also be used to manipulate the port
    definitions


semanage boolean can also be used to manipulate the
    booleans




system-config-selinux is a GUI tool available to customize
    SELinux policy settings.
