With this feature, session enable is now modified to have 3 modes of operation
session enable -- only enable session
session enable rt-backend sdl -- enable session with sdl
session enable rt-backend rule-table -- enable session with rule-table
session rule tables are now created on demand, upon adding first rule
to the rule table.
refactor session table to remove depenency from sesssion rules table. Now
session rules table APIs take srtg_handle and transport
proto instead of srt pointer.

When an application namespace is added, we call session_table_is_alloced
to see if we need to allocate a new session table. That check returns true
even if we removed the session table.
The fix is when we delete an application's global session table,
we need to invalidate fib_index_to_table_index.
Fixed test_vcl test script to run two tests back to back.
The 1st test deletes the application namespace at the end.
The 2nd test adds the application namespace in the beginning.

Rationale: running tshark binary takes about 100-150ms and if there are
thousands of pcap files, it takes minutes to decode them. This might not

Type: fix
fib_api_path_decode() is utilized by the IP route API call
to translate the path from the API to the fib_route_path_t
structure. The ip_route_add_del_handler_t function initializes
the fib_route_path_t structure to zeros, consequently setting
the sw_if_index value to 0, which is a valid value in VPP.
Typically, the default VRF (Virtual Routing and Forwarding)
has a local interface at index 0, leading to normal functionality.
However, a custom VRF table without any interface will result
in a crash.
The issue arises because the DROP route in fib_api_path_decode()
does not override the sw_if_index value with the one provided
in vl_api_fib_path_t. Subsequently, when this sw_if_index is
attempted to be resolved in the VRF table where the interface
does not exist, it leads to a crash.
This patch addresses the problem by setting the sw_if_index of
fib_route_path_t to the sw_if_index value of the API path.
To reproduce the issue, please remove the fix and run the following command:
make test-debug TEST=test_ip4.TestIPv4RouteLookup.test_exact_match

When the NIC does not support mac filter, we rely on ethernet-input
node to do the destination mac check, ie, when the interface is in L3,
the mac address for the packet must be the mac address of the
interface where the packet arrives. This works fine in ethernet-input
node when all packets in the frame might have different interfaces, ie,
ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is not set in the frame. However,
when all packets are having the same interface,
ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is set, ethernet-input node goes
through the optimized routine eth_input_single_int -> eth_input_process_frame.
That is where dmac check has a bug when all packets in the frame are
either, ip4, ip6, or mpls without vlan tags. Because without vlan tags,
the code handles all packets in fast path and ignores dmac check.
With vlan tags, the code goes to slow path where dmac check is handled
properly.
The fix is to check if we have a bad dmac in the fast path and force the
code to go to slow path which will handle dmac check properly.
Also do a wholesale correction on all the testcases which do not use
the proper dmac when sending L3 packets.

In case of multiple path within tunnel, mpls lookup node
computes lb hash with mpls_compute_flow_hash config value 0,
so only mpls label and l4 ports gets accounted, not 5-tuple.
This leads to flow traffic polarization and disbalance over
mpls paths.
Use mpls hash config from lb instead, usually it'll be
MPLS_FLOw_HASH_DEFAULT with 5-tuple plus flowlabel.
As optimization, fix flow hash reuse from the previous lookup
node if present, like ip_lookup does. Previously mpls lookup
always calcs the hash.
Test lb distribution for both cases.
Also, use the same flow hash hex format in ip4/ip6 and mpls
traces for easier reading, most code changes is due fixstyle

l2 tunnels like vxlan, gtpu, geneva use vnet_l2_compute_flow_hash() to
compute flow hash for udp src port entropy. In case of inner mpls tunnels
to the same lsr ethernet src and dst macs are the same, so l2 flow hash
is also the same leading to no src port entropy and the only rss queue
overflow on receiver side.
Fix it for all the possible vnet_l2_compute_flow_hash callers by making
mpls playload hash in additon to ip4/ip6. Visible performance impact is
not expected as it's only one check for mpls ethertype for common cases.

IPFIX buffers are stored on a per worker thread basis. Currently, the
flush callbacks will flush only buffers stored for the main thread. And
buffers for worker threads will not be sent until their size reach the
path MTU configured for the exporter. So if traffic is constant, the
problem will unlikely to be visible. Buffers will be sent once they
reach the maximum size. However, if traffic stops at some point and
flush is triggered in order to make the plugin send all currently
buffered data, this will not happen. And collectors will not receive
that data. The plugin will keep the remaining data until traffic starts
again, the buffers reach the maximum size, and be sent.
With this fix, flush buffers for worker threads and for the main thread
when the flush callbacks are triggered.
This will allow to remove @tag_fixme_vpp_workers from the unit tests
that don't set timers. The tests that set timers will still be failing

In esp_encrypt_inline(), if two or more consecutive packets are
associated with the same SA which has no crypto or integrity algorithms
set, only the first one gets dropped. Subsequent packets either get sent
(synchronous crypto) or cause a segv (asynchronous crypto).
The current SA's index and pool entry are cached before it can be
determined whether the packet should be dropped due to no algorithms
being set. The check for no algorithms is only performed when the cached
SA index is different than the SA index for the current packet. So
packets after the first one associated with the "none" alg SA aren't
handled properly.
This was broken by my previous commit ("ipsec: keep esp encrypt pointer
and index synced") which fixed a segv that occurred under a different
set of circumstances.
Check whether each packet should be dropped instead of only checking
when a new SA is encountered.
Update unit tests:
- Add a test for no algs on tunnel interface which enables
asynchronous crypto.
- Send more than one packet in the tests for no algs.
