xenstored(1M) System Administration Commands xenstored(1M)NAME
xenstored - xVM store daemon
SYNOPSIS
/usr/lib/xenstored
DESCRIPTION
The xenstored daemon provides control of the configuration of Solaris xVM domains.
Service Management Facility Support
The xenstored service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/xvm/store:default
The service's status can be queried using the svcs(1) command.
The service can be enabled successfully only when running under xVM.
At this time, attempts to restart the daemon can cause the failure of xVM management tools as well as running domains. If the daemon needs
to be restarted, a reboot is necessary.
FILES
/var/run/xenstored/tdb Configuration database.

xenstored_selinux(8) SELinux Policy xenstored xenstored_selinux(8)NAME
xenstored_selinux - Security Enhanced Linux Policy for the xenstored processes
DESCRIPTION
Security-Enhanced Linux secures the xenstored processes via flexible mandatory access control.
The xenstored processes execute with the xenstored_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 xenstored_t
ENTRYPOINTS
The xenstored_t SELinux type can be entered via the xenstored_exec_t file type.
The default entrypoint paths for the xenstored_t domain are the following:
/usr/sbin/xenstored, /usr/sbin/oxenstored
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 xenstored policy is very flexible allowing users to setup their xen-
stored processes in as secure a method as possible.
The following process types are defined for xenstored:
xenstored_t
Note: semanage permissive -a xenstored_t can be used to make the process type xenstored_t permissive. SELinux does not deny access to per-
missive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. xenstored policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run xenstored 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

The SELinux process type xenstored_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.

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 xenstored policy is very flexible allowing users to setup their
xenstored processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the xenstored, 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 xenstored_exec_t '/srv/xenstored/content(/.*)?'
restorecon -R -v /srv/myxenstored_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for xenstored:
xenstored_exec_t
- Set files with the xenstored_exec_t type, if you want to transition an executable to the xenstored_t domain.
Paths:
/usr/sbin/xenstored, /usr/sbin/oxenstored
xenstored_tmp_t
- Set files with the xenstored_tmp_t type, if you want to store xenstored temporary files in the /tmp directories.
xenstored_var_lib_t
- Set files with the xenstored_var_lib_t type, if you want to store the xenstored files under the /var/lib directory.
xenstored_var_log_t
- Set files with the xenstored_var_log_t type, if you want to treat the data as xenstored var log data, usually stored under the /var/log
directory.
xenstored_var_run_t
- Set files with the xenstored_var_run_t type, if you want to store the xenstored files under the /run or /var/run directory.
Paths:
/var/run/xenstored(/.*)?, /var/run/xenstore.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 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 boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
