This patches fixes an issue that could cause
fib locks to underflow: if an API user deletes
a fib and quickly recreates it, the fib may not
have been actually deleted. As a result, the
lock would not be incremented on the create call
leading to the fib potentially disappearing
afterwards - or to the lock to underflow when
the fib is deleted again.
In order to keep the existing API semantics,
we use the locks with API and CLI source as flags.
This means we need to use a different counter
for the interface-related locks.
This also prevents an issue where an interface being
bound to a vrf via API and released via CLI could
mess up the lock counter.
Finally, this will help with cleaning up the
interface-related locks on interface deletion
in a later patch.

IDr is optional in IKE AUTH from the initiator. In that case, the
responder is free to use any matching profile and fills the
corresponding IDr in the response.
The initiator is then free to accept or reject it.

This has two benefits: fix an issue where small packets can be
padded to 64 bytes by the ethernet layer, and we included these bytes
in the tcp stream; and also if we receive a small packet, it signals
that this tcp stream is likely more latency-sensitive than throughput-
sensitive, and skipping gro buffering should be beneficial.

Type: fix
When the local MAC address of an interface changes the rewrite strings
of all adjacency types need to be updated - this patch fixes the missing
case of incomplete adjacencies.
I moved the update of all adj types into the adj module, since if the
complete adjs were done by the ip-neighbour module and incomplete ones
by adj module, that would mean two walks of the adj DB, as it is not
possible to walk only a specific type.
UT is updated to include the missing case.

Type: fix
With endpoint dependent NAT44, When there are multiple workers we look
for a flow which matches the packet in order to figure out which worker
should handle the packet. If the packet is an ICMP error, it may be
associated with an existing flow by inspecting the L3/L4 headers that
are included in the message payload.
This was not being done for in2out packets in
nat44_ed_get_in2out_worker_index(), so some packets which were related
to an open session were not being associated with that session and were
being passed to a different thread than the one where the session was
created. Later on, when the packet was processed by the fast path in2out
node, the L3/L4 headers in the payload are inspected and the fast path
node finds the existing session. Since that session is owned by a
different thread than the one the packet is being processed by, the
in2out fast path node can potentially access the wrong session and/or
memory adjacent to the session pool. This can cause a SEGV.
Make nat44_ed_get_in2out_worker_index() look at the inner headers when
processing an ICMP error. THis is already done in
nat44_ed_get_out2in_worker_index() and in the fast path in2out node.

Type: fix
The NAT plugin stores packet counters and a counter represents a vector
indexed by interface index. When an interface is assigned a NAT role,
the counters are validated to be long enough for the given interface
index.
When a packet traverses NAT in2out and output feature is disabled, the
appropriate counters are updated by the RX interface index. In this
case, translation happens on the inside interface and its index was
ensured to be valid in all of the counters during NAT role assignment.
When a packet traverses NAT in2out and output feature is enabled, the
appropriate counters are updated by the RX interface index too. In this
case, translation happens on the outside interface and the packet could
be received on any interface, even with no NAT role assigned. If that's
the case and its index is greater than the greatest index validated in
the counters, a new counter value will be written to memory that does
not belong to the counter. As a result, a crash will occur at some
point.
With this change, use TX interface index to update the counters when
output feature is enabled. TX interface is an actual interface where
translation happens and its index is always valid in the counters.

forwarding gre payload
This commit introduces 2 fixes:
1) After GRE decapsulation sw_if_index[VLIB_TX] is set as fib index of GRE tunnel.
But since GRE tunnel can work on v4 endpoints and have v6 payload, we need to reset it.
In case we get IPv6 packet inside IPv4 GRE tunnel (or vice-versa) fib index can be (and usually is) invalid.
2) Check that ip-table and ip6-table are the same when setting interface as an unnumbered one.
Also, fix for the pipe test include setting the right unnumbered interface for the pipes

Type: fix
two problems;
1 - just because anti-reply is not enabled doesn't mean the high sequence
number should not be used.
- fix, there needs to be some means to detect a wrapped packet, so we
use a window size of 2^30.
2 - The SA object was used as a scratch pad for the high-sequence
number used during decryption. That means that once the batch has been
processed the high-sequence number used is lost. This means it is not
possible to distinguish this case:
if (seq < IPSEC_SA_ANTI_REPLAY_WINDOW_LOWER_BOUND (tl))
{
...
if (post_decrypt)
{
if (hi_seq_used == sa->seq_hi)
/* the high sequence number used to succesfully decrypt this
* packet is the same as the last-sequnence number of the SA.
* that means this packet did not cause a wrap.
* this packet is thus out of window and should be dropped */
return 1;
else
/* The packet decrypted with a different high sequence number
* to the SA, that means it is the wrap packet and should be
* accepted */
return 0;
}
- fix: don't use the SA as a scratch pad, use the 'packet_data' - the
same place that is used as the scratch pad for the low sequence number.
other consequences:
- An SA doesn't have seq and last_seq, it has only seq; the sequence
numnber of the last packet tx'd or rx'd.
- there's 64bits of space available on the SA's first cache line. move
the AES CTR mode IV there.
- test the ESN/AR combinations to catch the bugs this fixes. This
doubles the amount of tests, but without AR on they only run for 2
seconds. In the AR tests, the time taken to wait for packets that won't
arrive is dropped from 1 to 0.2 seconds thus reducing the runtime of
these tests from 10-15 to about 5 sceonds.
