varnishd_selinux(8) varnishd SELinux Policy documentation varnishd_selinux(8)NAMEvarnishd_selinux - Security Enhanced Linux Policy for the varnishd pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the varnishd processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. var‐
nishd policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run varnishd with the tightest access
possible.
If you want to allow varnishd to connect to all ports, not just HTTP,
you must turn on the varnishd_connect_any boolean.
setsebool -P varnishd_connect_any 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the var‐
nishd_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
varnishd_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the varnishd_t, you must
turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
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 varnishd policy is very flexible allowing users to setup their
varnishd processes in as secure a method as possible.
The following file types are defined for varnishd:
varnishd_etc_t
- Set files with the varnishd_etc_t type, if you want to store varnishd
files in the /etc directories.
varnishd_exec_t
- Set files with the varnishd_exec_t type, if you want to transition an
executable to the varnishd_t domain.
varnishd_initrc_exec_t
- Set files with the varnishd_initrc_exec_t type, if you want to tran‐
sition an executable to the varnishd_initrc_t domain.
varnishd_tmp_t
- Set files with the varnishd_tmp_t type, if you want to store varnishd
temporary files in the /tmp directories.
varnishd_var_lib_t
- Set files with the varnishd_var_lib_t type, if you want to store the
varnishd files under the /var/lib directory.
varnishd_var_run_t
- Set files with the varnishd_var_run_t type, if you want to store the
varnishd files under the /run directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
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 varnishd policy is very flexible allowing users to setup their
varnishd processes in as secure a method as possible.
The following port types are defined for varnishd:
varnishd_port_t
Default Defined Ports:
tcp 6081-6082
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
varnishd policy is very flexible allowing users to setup their varnishd
processes in as secure a method as possible.
The following process types are defined for varnishd:
varnishd_t, varnishlog_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
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 pol‐
icy 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 pol‐
icy settings.
