NAME
svirt_kvm_net_selinux - Security Enhanced Linux Policy for the svirt_kvm_net processes
DESCRIPTION
Security-Enhanced Linux secures the svirt_kvm_net processes via flexible mandatory access control.
The svirt_kvm_net processes execute with the svirt_kvm_net_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 svirt_kvm_net_t
ENTRYPOINTS
The svirt_kvm_net_t SELinux type can be entered via the file_type file type.
The default entrypoint paths for the svirt_kvm_net_t domain are the following:
all files on the system
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 svirt_kvm_net policy is very flexible allowing users to setup their
svirt_kvm_net processes in as secure a method as possible.
The following process types are defined for svirt_kvm_net:
svirt_kvm_net_t
Note: semanage permissive -a svirt_kvm_net_t can be used to make the process type svirt_kvm_net_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. svirt_kvm_net policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run svirt_kvm_net with the tightest access possible.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo-
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 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
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
If you want to allow sandbox containers to send audit messages, you must turn on the virt_sandbox_use_audit boolean. Enabled by default.
setsebool -P virt_sandbox_use_audit 1
If you want to allow sandbox containers to use netlink system calls, you must turn on the virt_sandbox_use_netlink boolean. Disabled by
default.
setsebool -P virt_sandbox_use_netlink 1
If you want to allow confined virtual guests to manage nfs files, you must turn on the virt_use_nfs boolean. Disabled by default.
setsebool -P virt_use_nfs 1
If you want to allow confined virtual guests to manage cifs files, you must turn on the virt_use_samba boolean. Disabled by default.
setsebool -P virt_use_samba 1
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the svirt_kvm_net_t, you
must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the svirt_kvm_net_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type svirt_kvm_net_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.
cgroup_t
/cgroup(/.*)?
/sys/fs/cgroup(/.*)?
cifs_t
nfs_t
svirt_home_t
/home/[^/]*/.libvirt/qemu(/.*)?
/home/[^/]*/.cache/libvirt/qemu(/.*)?
/home/[^/]*/.config/libvirt/qemu(/.*)?
/home/[^/]*/.local/share/gnome-boxes/images(/.*)?
svirt_sandbox_file_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 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.
