nova_compute_selinux(8) SELinux Policy nova_compute nova_compute_selinux(8)NAMEnova_compute_selinux - Security Enhanced Linux Policy for the nova_com‐
pute processes
DESCRIPTION
Security-Enhanced Linux secures the nova_compute processes via flexible
mandatory access control.
The nova_compute processes execute with the nova_compute_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 nova_compute_t
ENTRYPOINTS
The nova_compute_t SELinux type can be entered via the nova_com‐
pute_exec_t file type.
The default entrypoint paths for the nova_compute_t domain are the fol‐
lowing:
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
nova_compute policy is very flexible allowing users to setup their
nova_compute processes in as secure a method as possible.
The following process types are defined for nova_compute:
nova_compute_t
Note: semanage permissive -a nova_compute_t can be used to make the
process type nova_compute_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.
nova_compute policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run nova_compute with the tight‐
est 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 nova_compute_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.

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.
