[PATCH net 0/3] Netfilter fixes for net

[Pablo Neira Ayuso <pablo@netfilter.org>]

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:

Thanks!

P.S: Best wishes for 2021.
