[PATCH 2/2] netfilter: nf_reject_ipv4: Fix use-after-free in send_reset

From: Tejaswi Tanikella niph is not updated after pskb_expand_head changes the skb head. It still points to the freed data, which is then used to update tot_len and checksum. This could cause use-after-free poison crash. Update niph, if ip_route_me_harder does not fail.

[PATCH 1/2] netfilter: nft_set_hash: disable fast_ops for 2-len keys

From: Anatole Denis jhash_1word of a u16 is a different value from jhash of the same u16 with length 2. Since elements are always inserted in sets using jhash over the actual klen, this would lead to incorrect lookups on fixed-size sets with a key length of 2, as they would be
