Hi Jakub, David, The following patchset contains Netfilter fixes for net: 1) Missing sanitization of rateest userspace string, bug has been triggered by syzbot, patch from Florian Westphal. 2) Report EOPNOTSUPP on missing set features in nft_dynset, otherwise error reporting to userspace via EINVAL is misleading since this is reserved for malformed netlink requests. 3) New binaries with old kernels might silently accept several set element expressions. New binaries set on the NFT_SET_EXPR and NFT_DYNSET_F_EXPR flags to request for several expressions per element, hence old kernels which do not support for this bail out with EOPNOTSUPP. Please, pull these changes from: git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf.git Thanks!
