  • virtio-net: drop NETIF_F_FRAGLIST (Jason Wang) [Orabug:
    22145600] (CVE-2015-5156)

  • netdev: fix NETIF_F_GSO_UDP_TUNNEL_BIT enum shift in i40e driver import (Todd Vierling) [Orabug: 22066176]

  • xen/blkfront: remove redundant flush_op (Vitaly Kuznetsov) [Orabug: 21868758] - xen/blkfront: improve protection against issuing unsupported REQ_FUA (Vitaly Kuznetsov) [Orabug: 21868758]

  • xen-blkfront: introduce blkfront_gather_backend_features (Bob Liu) [Orabug: 20190614] - sched/x86: Fix up typo in topology detection (Dave Hansen) [Orabug: 21845184]
