[PATCH net-next 00/14] Netfilter updates for net-next

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

Hi,

The following patchset contains Netfilter updates for net-next:

1) Extended netlink error reporting if nfnetlink attribute parser fails,
   from Donald Hunter.

2) Incorrect request_module() module, from Simon Horman.

3) A series of patches to reduce memory consumption for set element transactions.
   Florian Westphal says:

"When doing a flush on a set or mass adding/removing elements from a
set, each element needs to allocate 96 bytes to hold the transactional
state.

In such cases, virtually all the information in struct nft_trans_elem
is the same.

Change nft_trans_elem to a flex-array, i.e. a single nft_trans_elem
can hold multiple set element pointers.

The number of elements that can be stored in one nft_trans_elem is limited
by the slab allocator, this series limits the compaction to at most 62
elements as it caps the reallocation to 2048 bytes of memory."

4) A series of patches to prepare the transition to dscp_t in .flowi_tos.
   From Guillaume Nault.

5) Support for bitwise operations with two source registers,
   from Jeremy Sowden.
