When starting a domain, if we find out domain requests security drivers we do not have loaded, we fail. However we don't check for this during reconnect, so any operation relying on security driver functionality would fail. If someone e.g. starts a domain with selinux driver loaded, then they turn off the security driver in config, restart the daemon and call dump/save/.., QEMU returns an error. As we shouldn't kill the domain, we should at least log an error to let the user know that domain reconnect wasn't completely clean. https://bugzilla.redhat.com/show_bug.cgi?id=1183893 --- src/qemu/qemu_process.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 56719eb..8da79e5 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -3747,6 +3747,12 @@ qemuProcessReconnect(void *opaque) if ((qemuDomainAssignAddresses(obj->def, priv->qemuCaps, obj)) < 0) goto error; + /* if domain requests security driver we haven't loaded, report error, but + * do not kill the domain + */ + ignore_value(virSecurityManagerCheckAllLabel(driver->securityManager, + obj->def)); +
Shouldn't you reset any possible error after that?
if (virSecurityManagerReserveLabel(driver->securityManager, obj->def, obj->pid) < 0)
goto error;
