We currently check current frags memory usage only when
a new frag queue is created. This allows attackers to first
consume the memory budget (default : 4 MB) creating thousands
of frag queues, then sending tiny skbs to exceed high_thresh
limit by 2 to 3 order of magnitude.

Note that before commit 648700f76b03 ("inet: frags: use rhashtables
for reassembly units"), work queue could be starved under DOS,
getting no cpu cycles.
After commit 648700f76b03, only the per frag queue timer can eventually
remove an incomplete frag queue and its skbs.

tcp: detect malicious patterns in tcp_collapse_ofo_queue()

[ Upstream commit 3d4bf93ac12003f9b8e1e2de37fe27983deebdcf ]

In case an attacker feeds tiny packets completely out of order,
tcp_collapse_ofo_queue() might scan the whole rb-tree, performing
expensive copies, but not changing socket memory usage at all.

1) Do not attempt to collapse tiny skbs.
2) Add logic to exit early when too many tiny skbs are detected.

We prefer not doing aggressive collapsing (which copies packets)
for pathological flows, and revert to tcp_prune_ofo_queue() which
will be less expensive.

In the future, we might add the possibility of terminating flows
that are proven to be malicious.

tcp: avoid collapses in tcp_prune_queue() if possible

[ Upstream commit f4a3313d8e2ca9fd8d8f45e40a2903ba782607e7 ]

Right after a TCP flow is created, receiving tiny out of order
packets allways hit the condition :

if (atomic_read(&sk->sk_rmem_alloc) >= sk->sk_rcvbuf)
tcp_clamp_window(sk);

tcp_clamp_window() increases sk_rcvbuf to match sk_rmem_alloc
(guarded by tcp_rmem[2])

Calling tcp_collapse_ofo_queue() in this case is not useful,
and offers a O(N^2) surface attack to malicious peers.

Better not attempt anything before full queue capacity is reached,
forcing attacker to spend lots of resource and allow us to more
easily detect the abuse.

tcp: free batches of packets in tcp_prune_ofo_queue()

[ Upstream commit 72cd43ba64fc172a443410ce01645895850844c8 ]

Juha-Matti Tilli reported that malicious peers could inject tiny
packets in out_of_order_queue, forcing very expensive calls
to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for
every incoming packet. out_of_order_queue rb-tree can contain
thousands of nodes, iterating over all of them is not nice.

Before linux-4.9, we would have pruned all packets in ofo_queue
in one go, every XXXX packets. XXXX depends on sk_rcvbuf and skbs
truesize, but is about 7000 packets with tcp_rmem[2] default of 6 MB.

Since we plan to increase tcp_rmem[2] in the future to cope with
modern BDP, can not revert to the old behavior, without great pain.

Strategy taken in this patch is to purge ~12.5 % of the queue capacity.

All adj delay are avalible is not fair when
fix adj mode were used for tuning.
We had tried to add all data with rx delay
to find out the unstable adj delay point.
This method can not cover all scene.
For example:
All adj delay are available as below.
ADJ   0   1   2   3   4   0   1
Src   --__--__--__--__--__--__--
D0    __________________--------
D1    __________________--------
D2    __________________--------
D3    __________________--------
when same rx delay were added to all data line.
All adj delay are still avalible as below.
ADJ   0   1   2   3   4   0   1
Src   --__--__--__--__--__--__--
D0    ----__________________----
D1    ----__________________----
D2    ----__________________----
D3    ----__________________----

So, a new method to find out the unstable adj point
were designed for better compatibility.
Rx delay were added on only 1 data line, such as D1.

When rx delay were added on D1 only. Adj delay 1 is
not available anymore as below.
ADJ   0   1   2   3   4   0   1
Src   --__--__--__--__--__--__--
D0    __________________--------
D1    ----__________________----
D2    __________________--------
D3    __________________--------

In this way, the unsatble adj delay could be
distinguished.
