  "message": "net: stmmac: copy XDP metadata in AF_XDP zero-copy RX\n\nstmmac_construct_skb_zc() reserves headroom for the XDP metadata and\nrecords the length reported by the XDP program, but only copies the\npacket data starting at xdp-\u003edata. The bytes in\n[xdp-\u003edata_meta, xdp-\u003edata) are never copied into the new skb, so the\nskb advertises metadata that is not there: after eth_type_trans()\nanchors mac_header, data_meta points at uninitialized headroom instead\nof what the program wrote.\n\nCopy the metadata together with the packet data starting at\nxdp-\u003edata_meta, leaving skb-\u003edata at the start of the frame and the\nmetadata immediately before it, and record its length. This keeps\ndata_meta valid for the stack and TC BPF after eth_type_trans() anchors\nmac_header.\n\nFixes: bba2556efad6 (\"net: stmmac: Enable RX via AF_XDP zero-copy\")\nSigned-off-by: Lorenzo Bianconi \u003clorenzo.bianconi@oss.qualcomm.com\u003e\nLink: https://patch.msgid.link/20261027-stmmac-xdp-fixes-v2-4-10eae8a093a8@oss.qualcomm.com\nSigned-off-by: Paolo Abeni \u003cpabeni@redhat.com\u003e\n",
