qemu_dm_selinux(8) SELinux Policy qemu_dm qemu_dm_selinux(8)NAMEqemu_dm_selinux - Security Enhanced Linux Policy for the qemu_dm pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the qemu_dm processes via flexible
mandatory access control.
The qemu_dm processes execute with the qemu_dm_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 qemu_dm_t
ENTRYPOINTS
The qemu_dm_t SELinux type can be entered via the qemu_dm_exec_t file
type.
The default entrypoint paths for the qemu_dm_t domain are the follow‐
ing:
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
qemu_dm policy is very flexible allowing users to setup their qemu_dm
processes in as secure a method as possible.
The following process types are defined for qemu_dm:
qemu_dm_t
Note: semanage permissive -a qemu_dm_t can be used to make the process
type qemu_dm_t permissive. SELinux does not deny access to permissive
process types, but the AVC (SELinux denials) messages are still gener‐
ated.
BOOLEANS
SELinux policy is customizable based on least access required. qemu_dm
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run qemu_dm with the tightest access possi‐
ble.
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 xend to run qemu-dm. Not required if using par‐
avirt and no vfb, you must turn on the xend_run_qemu boolean. Enabled
by default.
setsebool -P xend_run_qemu 1
MANAGED FILES
The SELinux process type qemu_dm_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.
xenfs_t
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.
