2017-02-08	netfilter: nft_ct: prepare for key-dependent error unwind	Florian Westphal	1	-14/+15
	Next patch will add ZONE_ID set support which will need similar error unwind (put operation) as conntrack labels. Prepare for this: remove the 'label_got' boolean in favor of a switch statement that can be extended in next patch. As we already have that in the set_destroy function place that in a separate function and call it from the set init function.

2017-02-08	netfilter: nft_ct: add zone id get support	Florian Westphal	2	-3/+21
	Just like with counters the direction attribute is optional. We set priv->dir to MAX unconditionally to avoid duplicating the assignment for all keys with optional direction. For keys where direction is mandatory, existing code already returns an error. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nf_tables: add bitmap set type	Pablo Neira Ayuso	3	-0/+321
	This patch adds a new bitmap set type. This bitmap uses two bits to represent one element. These two bits determine the element state in the current and the future generation that fits into the nf_tables commit protocol. When dumping elements back to userspace, the two bits are expanded into a struct nft_set_ext object. If no NFTA_SET_DESC_SIZE is specified, the existing automatic set backend selection prefers bitmap over hash in case of keys whose size is <= 16 bit. If the set size is know, the bitmap set type is selected if with 16 bit kets and more than 390 elements in the set, otherwise the hash table set implementation is used. For 8 bit keys, the bitmap consumes 66 bytes. For 16 bit keys, the bitmap takes 16388 bytes. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nf_tables: add space notation to sets	Pablo Neira Ayuso	4	-5/+21
	The space notation allows us to classify the set backend implementation based on the amount of required memory. This provides an order of the set representation scalability in terms of memory. The size field is still left in place so use this if the userspace provides no explicit number of elements, so we cannot calculate the real memory that this set needs. This also helps us break ties in the set backend selection routine, eg. two backend implementations provide the same performance. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nf_tables: rename struct nft_set_estimate class field	Pablo Neira Ayuso	4	-10/+10
	Use lookup as field name instead, to prepare the introduction of the memory class in a follow up patch. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nf_tables: add flush field to struct nft_set_iter	Pablo Neira Ayuso	2	-0/+5
	This provides context to walk callback iterator, thus, we know if the walk happens from the set flush path. This is required by the new bitmap set type coming in a follow up patch which has no real struct nft_set_ext, so it has to allocate it based on the two bit compact element representation.

2017-02-08	netfilter: nf_tables: rename deactivate_one() to flush()	Pablo Neira Ayuso	4	-13/+13
	Although semantics are similar to deactivate() with no implicit element lookup, this is only called from the set flush path, so better rename this to flush(). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nf_tables: use struct nft_set_iter in set element flush	Pablo Neira Ayuso	1	-7/+5
	Instead of struct nft_set_dump_args, remove unnecessary wrapper structure. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nf_tables: pass netns to set->ops->remove()	Pablo Neira Ayuso	4	-6/+9
	This new parameter is required by the new bitmap set type that comes in a follow up patch. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-08	netfilter: nft_exthdr: Add support for existence check	Phil Sutter	2	-2/+26
	If NFT_EXTHDR_F_PRESENT is set, exthdr will not copy any header field data into *dest, but instead set it to 1 if the header is found and 0 otherwise. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-03	net: skb_needs_check() accepts CHECKSUM_NONE for tx	Eric Dumazet	1	-3/+4
	My recent change missed fact that UFO would perform a complete UDP checksum before segmenting in frags. In this case skb->ip_summed is set to CHECKSUM_NONE.

2017-02-03	net: remove support for per driver ndo_busy_poll()	Eric Dumazet	4	-21/+0
	We added generic support for busy polling in NAPI layer in linux-4.5 No network driver uses ndo_busy_poll() anymore, we can get rid of the pointer in struct net_device_ops, and its use in sk_busy_loop() Saves NETIF_F_BUSY_POLL features bit.
