xenconsoled_selinux(8) SELinux Policy xenconsoled xenconsoled_selinux(8)NAMExenconsoled_selinux - Security Enhanced Linux Policy for the xencon‐
soled processes
DESCRIPTION
Security-Enhanced Linux secures the xenconsoled processes via flexible
mandatory access control.
The xenconsoled processes execute with the xenconsoled_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 xenconsoled_t
ENTRYPOINTS
The xenconsoled_t SELinux type can be entered via the xencon‐
soled_exec_t file type.
The default entrypoint paths for the xenconsoled_t domain are the fol‐
lowing:
/usr/sbin/xenconsoled
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
xenconsoled policy is very flexible allowing users to setup their xen‐
consoled processes in as secure a method as possible.
The following process types are defined for xenconsoled:
xenconsoled_t
Note: semanage permissive -a xenconsoled_t can be used to make the
process type xenconsoled_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. xencon‐
soled policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run xenconsoled with the tightest
access possible.
If you want to allow all daemons to write corefiles to /, you must turn
on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the
daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on
the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 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
MANAGED FILES
The SELinux process type xenconsoled_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 per‐
missions.

/etc/cluster(/.*)?
cluster_var_lib_t
/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?
cluster_var_run_t
/var/run/crm(/.*)?
/var/run/cman_.*
/var/run/rsctmp(/.*)?
/var/run/aisexec.*

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 xenconsoled policy is very flexible allowing users to setup
their xenconsoled processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the xenconsoled, 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 xenconsoled_exec_t '/srv/xenconsoled/con‐
tent(/.*)?'
restorecon -R -v /srv/myxenconsoled_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for xenconsoled:
xenconsoled_exec_t
- Set files with the xenconsoled_exec_t type, if you want to transition
an executable to the xenconsoled_t domain.
xenconsoled_var_run_t
- Set files with the xenconsoled_var_run_t type, if you want to store
the xenconsoled files under the /run or /var/run directory.
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.
