The RFC7857 state machine introduced in 56c492a is a trade-off.
It tries to retain sessions as much as possible and also offers
some protection against spurious RST by re-establishing sessions if data
is received after the RST. From experience in the wild, this algorithm is
a little too liberal, as it leaves too many spurious established sessions
in the session table.
E.g. a oberserved pattern is:
client server
<- FIN, ACK
ACK ->
ACK ->
RST, ACK ->
With the current state machine this would leave the session in established state.
These proposed changes do:
- require 3-way handshake to establish session.
(current requires only to see SYNs from both sides)
- RST will move session to transitory without recovery if data is sent after
- Only a single FIN is needed to move to transitory

Adding flow cache support to improve inbound IPv4/IPSec Security Policy
Database (SPD) lookup performance. By enabling the flow cache in startup
conf, this replaces a linear O(N) SPD search, with an O(1) hash table
search.
This patch is the ipsec4_input_node counterpart to
https://gerrit.fd.io/r/c/vpp/+/31694, and shares much of the same code,
theory and mechanism of action.
Details about the flow cache:
Mechanism:
1. First packet of a flow will undergo linear search in SPD
table. Once a policy match is found, a new entry will be added
into the flow cache. From 2nd packet onwards, the policy lookup
will happen in flow cache.
2. The flow cache is implemented using a hash table without collision
handling. This will avoid the logic to age out or recycle the old
flows in flow cache. Whenever a collision occurs, the old entry
will be overwritten by the new entry. Worst case is when all the
256 packets in a batch result in collision, falling back to linear
search. Average and best case will be O(1).
3. The size of flow cache is fixed and decided based on the number
of flows to be supported. The default is set to 1 million flows,
but is configurable by a startup.conf option.
4. Whenever a SPD rule is added/deleted by the control plane, all
current flow cache entries will be invalidated. As the SPD API is
not mp-safe, the data plane will wait for the control plane
operation to complete.
Cache invalidation is via an epoch counter that is incremented on
policy add/del and stored with each entry in the flow cache. If the
epoch counter in the flow cache does not match the current count,
the entry is considered stale, and we fall back to linear search.
The following configurable options are available through startup
conf under the ipsec{} entry:
1. ipv4-inbound-spd-flow-cache on/off - enable SPD flow cache
(default off)
2. ipv4-inbound-spd-hash-buckets %d - set number of hash buckets
(default 4,194,304: ~1 million flows with 25% load factor)
Performance with 1 core, 1 ESP Tunnel, null-decrypt then bypass,
94B (null encrypted packet) for different SPD policy matching indices:
SPD Policy index : 2 10 100 1000
Throughput : Mbps/Mbps Mbps/Mbps Mbps/Mbps Mbps/Mbps
(Baseline/Optimized)
ARM TX2 : 300/290 230/290 70/290 8.5/290

After changes made in f840880, VRRP IPv6 cannot reply for neighbor
solicitations requesting the link layer address of the configured
virtual address.
VRRP IPv6 enables the vrrp6-nd-input feature in the ip6-local feature
arc for an interface on which a virtual router is configured. When
neighbor solicitations arrive on that interface, ip6-local should start
feature arc walk for that interface and the messages should be processed
by vrrp6-nd-input. The problem is that currently, the feature arc is
started for the interface obtained from the receive DPO that has
interface unset (i.e. max u32) for local mfib entries. Thus, the feature
arc is started not on the interface the messages were received on and
vrrp6-nd-input is not traversed.
With this fix, if interface obtained from the receive DPO is unset, use
RX interface from the buffer to start the ip46-local feature arc.
Also, enable tests of this case for both IPv4 and IPv6 address families
that are currently tagged as extended and not run on every change. They
configure VRRP with priority 255 and are expected to be stable.

This patch fixes test_bihash_unittest in two ways:
1. The number of searches, namely tm->search_iter, defaults to 0,
thus disabling the test. This patch changes the default to 1.
2. Test errors are reported by clib_warning() instead of being
returned, thus the caller test/test_bihash.py is never aware of them.
This patch returns the errors constructed by clib_error_return().

In lcp_router_link_mtu(), either vnet_hw_interface_set_mtu() or
vnet_sw_interface_set_mtu() is called, based on whether this appears to
be a physical interface. The test to determine whether this is true was
incorrect and probably never worked right so vnet_sw_interface_set_mtu()
was always being called. This causes some breakage with Recent changes
to code which manages interface MTUs. Fix the test so the right function
is called.

The clib interrupt structure has a couple of fields at the start of
the cacheline, and then in the next cacheline it has a bitmap, which
is then followed by an atomic bitmap. The size of the bitmaps is
based on the number of interrupts, and when the memory is allocated
the number of interrupts needed is used to size the overall block of
memory. The interrupts typically map to pool entries, so if we want
to store 512 entries then we store them in indices 0..511. This
would then take 8 6 4bit words, so each bitmap would be this size
when the struct is allocated.
It is possible to walk over the end of the allocated data with certain
sizes, one of which is 512. The reason this happens with 512 is that
the check to see when to exit the loop is returning when offset is
greater than the value needed to fit all the values. In this case
512 >> 6 = 8. If there had only been 511 entries then the size would
have been 511 >> 6 = 7, and so it would have fitted in the space.
Therefore modify the check to also check that we are not looking into
the memory beyond what we have allocated in the case where the
number of interrupt is one of the boundary values like 512.
Also add a similar check first time round the loop as it is
possible we could have ate same problem there too.
Add a new test file to verify the new code works. The old version
of the code made this test fail when run with the address
sanitizer. Without the sanitiser it tended to pass because the
following memory was typically set to 0 even though it was
uninitialised.

An unexpected packet that shows up on a Wireguard interace
that happens not to have a forwarding peer will cause a
segfault trying to index the vector of peers by adjacency.
Rather than segfaulting, recognize a non-adjacent packet
and drop it instead.
This leaves open the question of what _should_ be
happening to, say, IPv6 multicast packets.
