- Summary
- netfilter: nf_dup_netdev: add nf_dev_xmit_recursion*() helpers and use them
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nfdupnetdev: add nfdevxmit_recursion*() helpers and use them
Update nftdup and nftfwd to use the nfdevxmit_recursion() helpers. This patch also disables BH when transmitting the skb to address a possible migration to different CPU leading to imbalanced decrementation of the recursion counters.
This is modeled after Florian Westphal's devxmitrecursion*() API available since commit 97cdcf37b57e ("net: place xmit recursion in softnet data") according to its current state in the tree.
