Spotted by syzkaller. 2) Fix esoteric bug in nf_queue with udp fraglist gro, broken since 6.11. Patch 3 adds extends the nfqueue selftest for this. 4) Use dedicated slab for flowtable entries, currently the -512 cache is used, which is wasteful. From Qingfang Deng. 5) Recent net-next update extended existing test for ip6ip6 tunnels, add the required /config entry. Test still passed by accident because the previous tests network setup gets re-used, so also update the test so it will fail in case the ip6ip6 tunnel interface cannot be added. 6) Fix 'nft get element mytable myset { 1.2.3.4 }' on big endian platforms, this was broken since code was added in v5.1. 7) Fix nf_tables counter reset support on 32bit platforms, where counter reset may cause huge values to appear due to wraparound. Broken since reset feature was added in v6.11. From Anders Grahn. 8-11) update nf_tables rbtree set type to detect partial operlaps. This will eventually speed up nftables userspace: at this time userspace does a netlink dump of the set content which slows down incremental updates on interval sets. From Pablo Neira Ayuso. * tag 'nf-next-26-02-06' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next: netfilter: nft_set_rbtree: validate open interval overlap netfilter: nft_set_rbtree: validate element belonging to interval netfilter: nft_set_rbtree: check for partial overlaps in anonymous sets netfilter: nft_set_rbtree: fix bogus EEXIST with NLM_F_CREATE with null interval netfilter: nft_counter: fix reset of counters on 32bit archs netfilter: nft_set_hash: fix get operation on big endian selftests: netfilter: add IPV6_TUNNEL to config netfilter: flowtable: dedicated slab for flow entry selftests: netfilter: nft_queue.sh: add udp fraglist gro test case netfilter: nfnetlink_queue: do shared-unconfirmed check before segmentation netfilter: nft_set_rbtree: don't gc elements on insert ==================== Link: https://patch.msgid.link/20260206153048.17570-1-fw@strlen.de Signed-off-by: Jakub Kicinski --- 792aaea994537daa78f31a86c948ccbefa8f4706
