[ Upstream commit a23ac973f67f37e77b3c634e8b1ad5b0164fcc1f ]
Ilya found a failure in running check-kernel tests with at_groups=144 (144: conntrack - FTP SNAT orig tuple) in OVS repo. After his further investigation, the root cause is that the labels sent to userspace for related ct are incorrect.
The labels for unconfirmed related ct should use its master's labels. However, the changes made in commit 8c8b73320805 ("openvswitch: set IPS_CONFIRMED in tmpl status only when commit is set in conntrack") led to getting labels from this related ct.
So fix it in ovs_ct_get_labels() by changing to copy labels from its master ct if it is a unconfirmed related ct. Note that there is no fix needed for ct->mark, as it was already copied from its master ct for related ct in init_conntrack().
