From: Dong Chenchen <dongchenchen2@huawei.com> This series adapts the upstream fix for CVE-2026-63983 to OLK-6.6. The CVE addresses a packet loop/recursion issue in netem when packet duplication is enabled. The upstream fix uses the skb tc_depth field, which is not present in OLK-6.6, so a prerequisite patch is included to add that field. The prerequisite patch backports the upstream commit that introduced skb->tc_depth (mainline 98b34f3e8c34), adapted to the OLK-6.6 sk_buff layout. The second patch applies the CVE fix itself (mainline 9552b11e3edabc97cfcd9f29103d5afbce7ae183) without further changes.
