spice-vdagent - Spice guest agent X11 session agent
SYNOPSIS
spice-vdagent [OPTIONS]
DESCRIPTION
The spice guest agent for Linux consists of 2 parts, a system wide daemon spice-vdagentd and a X11 session agent spice-vdagent of which
there is one per X11 session.
spice-vdagent gets automatically started in desktop environments which honor /etc/xdg/autostart, and under gdm.
FEATURES
The spice guest agent adds the following features to spice Linux guests:
Client mouse mode (no need to grab mouse by client, no mouse lag)
Automatic adjustment of the X11 session's number of virtual monitors, and their resolution, to the number of client windows and their reso-
lution
Support of copy and paste (text and images) between the active X11 session and the client, this supports both the primary selection and the
clipboard
Support for transfering files from the client to the agent
OPTIONS -h Print a short description of all command line options
-d Log debug messages
-s port
Set virtio serial port (default: /dev/virtio-ports/com.redhat.spice.0)
-x Don't daemonize
-f dir|xdg-desktop|xdg-download
Set directory where to save files send from the client, this can be either an arbitrary dir or one of the special values of xdg-
desktop or xdg-download to select the default xdg Desktop resp. xdg Download directory. If no value is specified the default is xdg-
desktop when running under a Desktop Environment which has icons on the desktop and xdg-download under other Desktop Environments
-o 0|1 Disable/enable opening the file save directory with xdg-open (showing the directory in the file manager) when a file transfer from
the client completes. If no value is specified the default is 0 when running under a Desktop Environment which has icons on the
desktop and 1 under other Desktop Environments

vdagent_selinux - Security Enhanced Linux Policy for the vdagent processes
DESCRIPTION
Security-Enhanced Linux secures the vdagent processes via flexible mandatory access control.
The vdagent processes execute with the vdagent_t SELinux type. You can check if you have these processes running by executing the ps com-
mand with the -Z qualifier.
For example:
ps -eZ | grep vdagent_t
ENTRYPOINTS
The vdagent_t SELinux type can be entered via the vdagent_exec_t file type.
The default entrypoint paths for the vdagent_t domain are the following:
/usr/sbin/spice-vdagentd
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 vdagent policy is very flexible allowing users to setup their vdagent
processes in as secure a method as possible.
The following process types are defined for vdagent:
vdagent_t
Note: semanage permissive -a vdagent_t can be used to make the process type vdagent_t permissive. SELinux does not deny access to permis-
sive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. vdagent policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run vdagent 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 vdagent_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.
cluster_conf_t
/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.*
/var/run/heartbeat(/.*)?
/var/run/cpglockd.pid
/var/run/corosync.pid
/var/run/rgmanager.pid
/var/run/cluster/rgmanager.sk
root_t
/
/initrd
vdagent_var_run_t
/var/run/spice-vdagentd(/.*)?
/var/run/spice-vdagentd.pid
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 vdagent policy is very flexible allowing users to setup their
vdagent processes in as secure a method as possible.
EQUIVALENCE DIRECTORIES
vdagent policy stores data with multiple different file context types under the /var/run/spice-vdagentd directory. If you would like to
store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this
data under the /srv dirctory you would execute the following command:
semanage fcontext -a -e /var/run/spice-vdagentd /srv/spice-vdagentd
restorecon -R -v /srv/spice-vdagentd
vdagent policy stores data with multiple different file context types under the /var/log/spice-vdagentd directory. If you would like to
store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this
data under the /srv dirctory you would execute the following command:
semanage fcontext -a -e /var/log/spice-vdagentd /srv/spice-vdagentd
restorecon -R -v /srv/spice-vdagentd
STANDARD FILE CONTEXT
SELinux defines the file context types for the vdagent, if you wanted to store files with these types in a diffent paths, you need to exe-
cute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t vdagent_exec_t '/srv/vdagent/content(/.*)?'
restorecon -R -v /srv/myvdagent_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for vdagent:
vdagent_exec_t
- Set files with the vdagent_exec_t type, if you want to transition an executable to the vdagent_t domain.
vdagent_log_t
- Set files with the vdagent_log_t type, if you want to treat the data as vdagent log data, usually stored under the /var/log directory.
Paths:
/var/log/spice-vdagentd(/.*)?, /var/log/spice-vdagentd.log.*
vdagent_var_run_t
- Set files with the vdagent_var_run_t type, if you want to store the vdagent files under the /run or /var/run directory.
Paths:
/var/run/spice-vdagentd(/.*)?, /var/run/spice-vdagentd.pid
vdagentd_initrc_exec_t
- Set files with the vdagentd_initrc_exec_t type, if you want to transition an executable to the vdagentd_initrc_t domain.
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.
