ipsec_mgmt_selinux(8) SELinux Policy ipsec_mgmt ipsec_mgmt_selinux(8)NAMEipsec_mgmt_selinux - Security Enhanced Linux Policy for the ipsec_mgmt
processes
DESCRIPTION
Security-Enhanced Linux secures the ipsec_mgmt processes via flexible
mandatory access control.
The ipsec_mgmt processes execute with the ipsec_mgmt_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 ipsec_mgmt_t
ENTRYPOINTS
The ipsec_mgmt_t SELinux type can be entered via the ipsec_mgmt_exec_t,
shell_exec_t file types.
The default entrypoint paths for the ipsec_mgmt_t domain are the fol‐
lowing:
/usr/sbin/ipsec, /usr/sbin/strongswan, /usr/lib/ipsec/_plutorun,
/usr/lib/ipsec/_plutoload, /usr/libexec/ipsec/_plutorun,
/usr/libexec/ipsec/_plutoload, /usr/libexec/nm-openswan-service,
/bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/zsh.*,
/usr/bin/ksh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,

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
ipsec_mgmt policy is very flexible allowing users to setup their
ipsec_mgmt processes in as secure a method as possible.
The following process types are defined for ipsec_mgmt:
ipsec_mgmt_t
Note: semanage permissive -a ipsec_mgmt_t can be used to make the
process type ipsec_mgmt_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.
ipsec_mgmt policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run ipsec_mgmt with the tightest
access possible.
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 authlo‐
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow all daemons the ability to read/write terminals,
you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors,
you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you
must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn
on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 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. Disabled by default.
setsebool -P nscd_use_shm 1
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server for the ipsec_mgmt_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
ipsec_mgmt_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type ipsec_mgmt_t can manage files labeled with the
following file types. The paths listed are the default paths for these
file types. Note the processes UID still need to have DAC permissions.

/etc/ipsec.d(/.*)?
/etc/racoon/certs(/.*)?
/etc/ipsec.secrets.*

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 ipsec_mgmt policy is very flexible allowing users to setup
their ipsec_mgmt processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the ipsec_mgmt, 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 ipsec_mgmt_exec_t '/srv/ipsec_mgmt/con‐
tent(/.*)?'
restorecon -R -v /srv/myipsec_mgmt_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for ipsec_mgmt:
ipsec_mgmt_exec_t
- Set files with the ipsec_mgmt_exec_t type, if you want to transition
an executable to the ipsec_mgmt_t domain.
Paths:
/usr/sbin/ipsec, /usr/sbin/strongswan, /usr/lib/ipsec/_plutorun,
/usr/lib/ipsec/_plutoload, /usr/libexec/ipsec/_plutorun,
/usr/libexec/ipsec/_plutoload, /usr/libexec/nm-openswan-service
ipsec_mgmt_lock_t
- Set files with the ipsec_mgmt_lock_t type, if you want to treat the
files as ipsec mgmt lock data, stored under the /var/lock directory
Paths:
/var/lock/subsys/ipsec, /var/lock/subsys/strongswan
ipsec_mgmt_unit_file_t
- Set files with the ipsec_mgmt_unit_file_t type, if you want to treat
the files as ipsec mgmt unit content.
ipsec_mgmt_var_run_t
- Set files with the ipsec_mgmt_var_run_t type, if you want to store
the ipsec mgmt files under the /run or /var/run directory.
Paths:
/var/run/pluto/ipsec.info, /var/run/pluto/ipsec_setup.pid
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 data‐
base. 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 pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
