Pablo Neira Ayuso says: ==================== Netfilter fixes for net 1) Fix crash with malformed ebtables blob which do not provide all entry points, from Florian Westphal. 2) Fix possible TCP connection clogging up with default 5-days timeout in conntrack, from Florian. 3) Fix crash in nf_tables tproxy with unsupported chains, also from Florian. 4) Do not allow to update implicit chains. 5) Make table handle allocation per-netns to fix data race. 6) Do not truncated payload length and offset, and checksum offset. Instead report EINVAl. 7) Enable chain stats update via static key iff no error occurs. 8) Restrict osf expression to ip, ip6 and inet families. 9) Restrict tunnel expression to netdev family. 10) Fix crash when trying to bind again an already bound chain. 11) Flowtable garbage collector might leave behind pending work to delete entries. This patch comes with a previous preparation patch as dependency. 12) Allow net.netfilter.nf_conntrack_frag6_high_thresh to be lowered, from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_defrag_ipv6: allow nf_conntrack_frag6_high_thresh increases netfilter: flowtable: fix stuck flows on cleanup due to pending work netfilter: flowtable: add function to invoke garbage collection immediately netfilter: nf_tables: disallow binding to already bound chain netfilter: nft_tunnel: restrict it to netdev family netfilter: nft_osf: restrict osf to ipv4, ipv6 and inet families netfilter: nf_tables: do not leave chain stats enabled on error netfilter: nft_payload: do not truncate csum_offset and csum_type netfilter: nft_payload: report ERANGE for too long offset and length netfilter: nf_tables: make table handle allocation per-netns friendly netfilter: nf_tables: disallow updates of implicit chain netfilter: nft_tproxy: restrict to prerouting hook netfilter: conntrack: work around exceeded receive window netfilter: ebtables: reject blobs that don't provide all entry points ==================== Link: https://lore.kernel.org/r/20220824220330.64283-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
