nf_dev_xmit_recursion*() helpers and use them\n\nUpdate nft_dup and nft_fwd to use the nf_dev_xmit_recursion() helpers.\nThis patch also disables BH when transmitting the skb to address a\npossible migration to different CPU leading to imbalanced decrementation\nof the recursion counters.\n\nThis is modeled after Florian Westphal's dev_xmit_recursion*() API\navailable since commit 97cdcf37b57e (\"net: place xmit recursion in\nsoftnet data\") according to its current state in the tree.","state":0,"publishedAt":"2026-08-15T05:57:37.579+00:00","modifiedAt":"2026-10-15T10:08:50.087+00:00","affected":[{"ecosystem":"Vendor
