Pablo Neira Ayuso says: ==================== Netfilter/IPVS fixes for net The following patchset contains Netfilter/IPVS fixes for your net tree, they are: 1) Validate hooks for nf_tables NAT expressions, otherwise users can crash the kernel when using them from the wrong hook. We already got one user trapped on this when configuring masquerading. 2) Fix a BUG splat in nf_tables with CONFIG_DEBUG_PREEMPT=y. Reported by Andreas Schultz. 3) Avoid unnecessary reroute of traffic in the local input path in IPVS that triggers a crash in in xfrm. Reported by Florian Wiessner and fixes by Julian Anastasov. 4) Fix memory and module refcount leak from the error path of nf_tables_newchain(). ==================== Signed-off-by: David S.
