This introduces 5-tuple lookup tables that may be used to implement
custom session layer actions at connection establishment time (session
layer perspective).
The rules table build mask-match-action lookup trees that for a given
5-tuple key return the action for the first longest match. If rules
overlap, ordering is established by tuple longest match with the
following descending priority: remote ip, local ip, remote port, local
port.
At this time, the only match action supported is to forward packets to
the application identified by the action.

Make it easier to integrate with external IKE daemon.
IPsec interfaces can have one or both SAs replaced after
creation. This allows for the possibility of setting a
new child SA on an interface when rekeying occurs. It also
allows for the possibility of creating an interface ahead
of time and updating the SA when parameters that are
negotiated during IKE exchange become known.

- Global variables declared in header files without
the use of the 'extern' keword will result in multiple
instances of the variable to be created by the compiler
-- one for each different source file in which the
the header file is included. This results in wasted
memory allocated in the BSS segments as well as
potentially introducing bugs in the application.

Any u8* variable created by format() is NOT null-terminated.
Add the null terminating byte with vec_terminate_c_string().
If that variable is used by (at least) hash_get_mem(), then it needs to
be null-terminated, as it will go through string_key_sum() which makes a
call to strlen.

Vat supports setting value for the parameter, but
'not_last' is ignored by ip_add_del_route handler,
so can be removed.
This patch
- updates ip.api,
- removes vat handlers
- updates vpp_papi_provider.py
(also mpls_route_add_del with unused not_last)

With heavy traffic, tx code path may crash due to memory corruption
Thread 5 "vpp_wk_2" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fff3995c700 (LWP 2505)]
0x00007ffff73675e8 in vhost_user_if_input (vm=0x7fffb5f5bf9c,
vum=0x7ffff7882a40 <vhost_user_main>, vui=0x7fffb65570c4, qid=0,
node=0x7fffb6577dac, mode=VNET_HW_INTERFACE_RX_MODE_POLLING)
at /home/sluong/vpp-master/vpp/build-data/../src/vnet/devices/virtio/vhost-user.c:1610
1610 bi_current = (vum->cpus[thread_index].rx_buffers)
[vum->cpus[thread_index].rx_buffers_len];
(gdb) p vum->cpus[thread_index].rx_buffers_len
$2 = 793212607
(gdb)
Apparently, some code accidentally wrote the bad value in rx_buffers_len.
rx_buffers_len should never be greater than 1024 since that is how many buffers
we request each time.
After debugging many hours, I discovered that the memory corruption happens
in the tx code path right here on line 2176.
{
vhost_copy_t *cpy = &vum->cpus[thread_index].copy[copy_len];
copy_len++;
cpy->len = bytes_left;
cpy->len = (cpy->len > buffer_len) ? buffer_len : cpy->len;
cpy->dst = buffer_map_addr;
cpy->src = (uword) vlib_buffer_get_current (current_b0) +
current_b0->current_length - bytes_left;
(gdb) p cpy
$3 = (vhost_copy_t *) 0x7fffb554077c
(gdb) p copy_len
$4 = 1025
(gdb) p &vum->cpus[3].rx_buffers_len
$8 = (u32 *) 0x7fffb5540784
copy_len is picking up the index entry 1024 before it was incremented. copy array has only
1024 members (0 - 1023 are valid).
The assignment here in cpy surely causes memory corruption. It is only discovered later
when the memory location that it corrupted is used.
The condition for the crash is to transmit jumbo frames under heavy volume. Since ring
size is 1024, with one packet taking up one index for frame size (less 2048), it does
not cause overflow. With jumbo frames, it requires multiple indices for one packet,
it can cause the overflow under heavy traffic.
The fix is to do copy out when we have 1000 entries in the array to avoid
overflow.

This patch is a plausible first-cut, suitable for initial testing by
vcl (host stack client library).
Main features;
- recursive name resolution
- multiple ip4/ip6 name servers
- cache size limit enforcement
- currently limited to 65K
- ttl / aging
- static mapping support
- show / clear / debug CLI commands
Binary APIs provided for the following:
- add/delete name servers
- enable/disable the name cache
- resolve a name
To Do list:
- Respond to ip4/ip6 client DNS requests (vs. binary API requests)
- Perf / scale tuning
- map pending transaction ids to pool indices, so the cache
can (greatly) exceed 65K entries
- Security improvements
- Use unpredictable dns transaction IDs, related to previous item
- Make sure that response-packet src ip addresses match the server
- Add binary APIs
- deliver raw response data to clients
- control recursive name resolution
- Documentation

Applications are now provided the option to select the namespace they
are to be attached to and the scope of their attachement. Application
namespaces are meant to:
1) constrain the scope of communication through the network by
association with source interfaces and/or fib tables that provide the
source ips to be used and limit the scope of routing
2) provide a namespace local scope to session layer communication, as
opposed to the global scope provided by 1). That is, sessions can be
established without assistance from transport and network layers.
Albeit, zero/local-host ip addresses must still be provided in session
establishment messages due to existing application idiosyncrasies. This
mode of communication uses shared-memory fifos (cut-through sessions)
exclusively.
If applications request no namespace, they are assigned to the default
one, which at its turn uses the default fib. Applications can request
access to both local and global scopes for a namespace. If no scope is
specified, session layer defaults to the global one.
When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY)
binds are converted to binds to the requested interface.
