NAME¶

virt_qmf_selinux - Security Enhanced Linux Policy for the virt_qmf processes

DESCRIPTION¶

Security-Enhanced Linux secures the virt_qmf processes via flexible mandatory access control.

The virt_qmf processes execute with the virt_qmf_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 virt_qmf_t

ENTRYPOINTS¶

The virt_qmf_t SELinux type can be entered via the virt_qmf_exec_t file type.

The default entrypoint paths for the virt_qmf_t domain are the following:

/usr/bin/libvirt-qmf

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 virt_qmf policy is very flexible allowing users to setup their virt_qmf processes in as secure a method as possible.

The following process types are defined for virt_qmf:

virt_qmf_t

Note: semanage permissive -a virt_qmf_t can be used to make the process type virt_qmf_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. virt_qmf policy is extremely flexible and has several booleans that allow you to manipulate the policy and run virt_qmf with the tightest access possible.

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 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

MANAGED FILES¶

The SELinux process type virt_qmf_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

/run/crm(/.*)?
/run/cman_.*
/run/rsctmp(/.*)?
/run/aisexec.*
/run/heartbeat(/.*)?
/run/pcsd-ruby.socket
/run/corosync-qnetd(/.*)?
/run/corosync-qdevice(/.*)?
/run/pcsd.socket
/run/corosync.pid
/run/cpglockd.pid
/run/rgmanager.pid
/run/cluster/rgmanager.sk

root_t

/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp

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 virt_qmf policy is very flexible allowing users to setup their virt_qmf processes in as secure a method as possible.

STANDARD FILE CONTEXT

SELinux defines the file context types for the virt_qmf, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t virt_qmf_exec_t '/srv/virt_qmf/content(/.*)?'
restorecon -R -v /srv/myvirt_qmf_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for virt_qmf:

virt_qmf_exec_t

- Set files with the virt_qmf_exec_t type, if you want to transition an executable to the virt_qmf_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.
