Pablo Neira Ayuso says: ==================== Netfilter/IPVS fixes for net The following patchset contains Netfilter/IPVS fixes for your net tree: 1) Reject non-null terminated helper names from xt_CT, from Gao Feng. 2) Fix KASAN splat due to out-of-bound access from commit phase, from Alexey Kodanev. 3) Missing conntrack hook registration on IPVS FTP helper, from Julian Anastasov. 4) Incorrect skbuff allocation size in bridge nft_reject, from Taehee Yoo. 5) Fix inverted check on packet xmit to non-local addresses, also from Julian. 6) Fix ebtables alignment compat problems, from Alin Nastac. 7) Hook mask checks are not correct in xt_set, from Serhey Popovych. 8) Fix timeout listing of element in ipsets, from Jozsef. 9) Cap maximum timeout value in ipset, also from Jozsef. 10) Don't allow family option for hash:mac sets, from Florent Fourcot. 11) Restrict ebtables to work with NFPROTO_BRIDGE targets only, this Florian. 12) Another bug reported by KASAN in the rbtree set backend, from Taehee Yoo. 13) Missing __IPS_MAX_BIT update doesn't include IPS_OFFLOAD_BIT. From Gao Feng. 14) Missing initialization of match/target in ebtables, from Florian Westphal. 15) Remove useless nft_dup.h file in include path, from C. Labbe. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
