[PATCH stable 4.9 28/29] ip: process in-order fragments efficiently

[PATCH stable 4.9 17/29] inet: frags: get rid of ipfrag_skb_cb/FRAG_CB

From: Eric Dumazet ip_defrag uses skb->cb[] to store the fragment offset, and unfortunately this integer is currently in a different cache line than skb->next, meaning that we use two cache lines per skb when finding the insertion point. By aliasing skb->ip_defrag_offset and skb->dev, we pack

[PATCH stable 4.9 22/29] ipv6: defrag: drop non-last frags smaller than min mtu

From: Florian Westphal don't bother with pathological cases, they only waste cycles. IPv6 requires a minimum MTU of 1280 so we should never see fragments smaller than this (except last frag). v3: don't use awkward "-offset + len" v2: drop IPv4 part, which added same check w. IPV4_MIN_MTU (68).

[PATCH stable 4.9 08/29] inet: frags: use rhashtables for reassembly units

From: Eric Dumazet Some applications still rely on IP fragmentation, and to be fair linux reassembly unit is not working under any serious load. It uses static hash tables of 1024 buckets, and up to 128 items per bucket (!!!) A work queue is supposed to garbage collect items when host is under

[PATCH stable 4.9 07/29] rhashtable: add schedule points

[PATCH stable 4.9 23/29] net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends

From: Eric Dumazet After working on IP defragmentation lately, I found that some large packets defeat CHECKSUM_COMPLETE optimization because of NIC adding zero paddings on the last (small) fragment. While removing the padding with pskb_trim_rcsum(), we set skb->ip_summed to CHECKSUM_NONE,

[PATCH stable 4.9 10/29] inet: frags: get rif of inet_frag_evicting()

From: Eric Dumazet This refactors ip_expire() since one indentation level is removed. Note: in the future, we should try hard to avoid the skb_clone() since this is a serious performance cost. Under DDOS, the ICMP message wont be sent because of rate limits. Fact that ip6_expire_frag_queue()
