Re: [libvirt] [PATCH] leaseshelper: fix crash when no mac is specified

If dnsmasq specified DNSMASQ_IAID (so we're dealing with an IPv6 lease) but no DNSMASQ_MAC, we skip creation of the new lease object. Also skip adding it to the leases array. https://bugzilla.redhat.com/show_bug.cgi?id=1202350 https://bugzilla.redhat.com/show_bug.cgi?id=1292941 --- src/network/leaseshelper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/network/leaseshelper.c b/src/network/leaseshelper.c index 2d528f7..6930310 100644 --- a/src/network/leaseshelper.c +++ b/src/network/leaseshelper.c @@ -439,7 +439,7 @@ main(int argc, char **argv) case VIR_LEASE_ACTION_OLD: case VIR_LEASE_ACTION_ADD: - if (virJSONValueArrayAppend(leases_array_new, lease_new) < 0) { + if (lease_new && virJSONValueArrayAppend(leases_array_new, lease_new) < 0) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("failed to create json")); goto cleanup;
