Pablo Neira Ayuso says: ==================== Netfilter updates for net-next (v2) The following series contains an initial small batch of Netfilter updates for net-next: 1) Remove DCCP conntrack support, keep DCCP matches around in order to avoid breakage when loading ruleset, add Kconfig to wrap the code so it can be disabled by distributors. 2) Remove buggy code aiming at shrinking netlink deletion event, then re-add it correctly in another patch. This is to prevent -stable to pick up on a fix that breaks old userspace. From Phil Sutter. 3) Missing WARN_ON_ONCE() to check for lockdep_commit_lock_is_held() to uncover bugs. From Fedor Pchelkin. * tag 'nf-next-25-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next: netfilter: nf_tables: adjust lockdep assertions handling netfilter: nf_tables: Reintroduce shortened deletion notifications netfilter: nf_tables: Drop dead code from fill_*_info routines netfilter: conntrack: remove DCCP protocol support ==================== Link: https://patch.msgid.link/20250710010706.2861281-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
