While before the my_client_index variable was stored as global variable
in api_main_t, after commit 2ca88ff978
the my_client_index becomes part of vapi_ctx_t.
Each API client (internal/external) connected to VPP stores its
client index in vapi_ctx_t.
The issue is in the client disconnection. The vapi_disconnect is
untouched in patch 2ca88ff978,
so it keeps the behavior of using the my_client_index stored
in api_main_t.

Add a new tool packetforge to extras. This tool is to support generic flow.
Packetforge is a library to translate naming or json profile format flow
pattern to the required input of generic flow, i.e. spec and mask. Using
python script flow_create.py, it can add and enable a new flow rule for
an interface via flow VAPI, and can delete an existed flow rule as well.
Command examples are shown below. Json profile examples can be found in
./parsegraph/samples.
Naming format input:
python flow_create.py --add -p "mac()/ipv4(src=1.1.1.1,dst=2.2.2.2)/udp()"
-a "redirect-to-queue 3" -i 1
python flow_create.py --del -i 1 -I 0
Json profile format input:
python flow_create.py -f "./flow_rule_examples/mac_ipv4.json" -i 1
With this command, flow rule can be added or deleted, and the flow
entry can be listed with "show flow entry" command in VPP CLI.
Packetforge is based on a parsegraph. The parsegraph can be built by
users. A Spec can be found in ./parsegraph as guidance. More details
about packetforge are in README file.

The number of available dynamic ports is set to (0xffff - 1024) =
64511, which is not divisable by the pow2 number of workers - the
only integer divisors are 31 and 2081.
So, total dynamic port range of all workers will be less than it:
1 wrk: n = (port_per_thread = 64511/1)*1 = 64511 + 1025 = 65536
2 wrk: n = (port_per_thread = 64511/2)*2 = 64510 + 1025 = 65535
4 wrk: n = (port_per_thread = 64511/4)*4 = 64508 + 1025 = 65533
8 wrk: n = (port_per_thread = 64511/8)*8 = 64504 + 1025 = 65529
...
As seen, with multiple workers there are unused trailing ports for every
nat pool address and that is the reason of out-of-bound index in the
worker array on out2in path due (port - 1024) / port_per_thread math.
This was fixed in 5c9f9968de, so packets
to unused ports will go to existing worker and dropped there.
Per RFC 6335 https://www.rfc-editor.org/rfc/rfc6335#section-6:
6. Port Number Ranges
o the System Ports, also known as the Well Known Ports, from 0-1023
(assigned by IANA)
o the User Ports, also known as the Registered Ports, from 1024-
49151 (assigned by IANA)
o the Dynamic Ports, also known as the Private or Ephemeral Ports,
from 49152-65535 (never assigned)
According that let's allocate dynamic ports from 1024 and have full port
range with a wide range of the workers number - 64 integer divisors in
total, including pow2 ones:
1 wrk: n = (port_per_thread = 64512/1)*1 = 64512 + 1024 = 65536
2 wrk: n = (port_per_thread = 64512/2)*2 = 64512 + 1024 = 65536
3 wrk: n = (port_per_thread = 64512/3)*3 = 64512 + 1024 = 65536
4 wrk: n = (port_per_thread = 64512/4)*4 = 64512 + 1024 = 65536
5 wrk: n = (port_per_thread = 64512/5)*5 = 64510 + 1024 = 65534
6 wrk: n = (port_per_thread = 64512/6)*6 = 64512 + 1024 = 65536
7 wrk: n = (port_per_thread = 64512/7)*7 = 64512 + 1024 = 65536
8 wrk: n = (port_per_thread = 64512/8)*8 = 64512 + 1024 = 65536
...
Modulo from 5c9f9968de is still required
when the numbers of workers is not the integer divisor of 64512.

When there is a bad descriptor, it may in the beginning, in the middle,
or at the end of the batch if the batch has more than 3 descriptors.
When processing a bad descriptor is encountered in the batch, we need to
rollback n_buffers in memif_process_desc(), or the statement in the same
function
memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy,
dst_off, n_buffers - 1);
is wrong because it picks up the wrong buffer_vec_index of the bad
descriptor while parsing a good descriptor immediately following the
bad descriptor. n_buffers was incremented in the beginning of
while (n_left) loop.
The other problem is we should count the number of bad packets and
reduce ptd->n_packets to get the correct number of packets for subsequent
processing in device_input.
The last fix is to check if n_buffers == 0 in device_input and skip
doing any descriptor copy. This case can happen when all the descriptors
are bad in the batch.

This patch introduces DMA infrastructure into vlib. This is well known
that large amount of memory movements will drain core resource. Nowadays
more and more hardware accelerators were designed out for freeing core
from this burden. Meanwhile some restrictions still remained when
utilizing hardware accelerators, e.g. cross numa throughput will have a
significant drop compared to same node. Normally the number of hardware
accelerator instances will less than cores number, not to mention that
applications number will even beyond the number of cores. Some hardware
may support share virtual address with cores, while others are not.
Here we introduce new DMA infrastructure which can fulfill the
requirements of vpp applications like session and memif and in the
meantime dealing with hardware limitations.
Here is some design backgrounds:
Backend is the abstract of resource which allocated from DMA device
and can do some basic operations like configuration, DMA copy and
result query.
Config is the abstract of application DMA requirement. Application
need to request an unique config index from DMA infrastructure. This
unique config index is associated with backend resource. Two options
cpu fallback and barrier before last can be specified in config.
DMA transfer will be performed by CPU when backend is busy if cpu
fallback option is enabled. DMA transfer callback will be in order
if barrier before last option is enabled.
We constructs all the stuffs that DMA transfer request needed into
DMA batch. It contains the pattern of DMA descriptors and function
pointers for submission and callback. One DMA transfer request need
multiple times batch update and one time batch submission.
DMA backends will assigned to config's workers threads equally. Lock
will be used for thread-safety if same backends assigned to multiple
threads. Backend node will check all the pending requests in worker
thread and do callback with the pointer of DMA batch if transfer
completed. Application can utilize cookie in DMA batch for selves
usage.
DMA architecture:
+----------+ +----------+ +----------+ +----------+
| Config1 | | Config2 | | Config1 | | Config2 |

Previously, each address maintained an array of 32-bit
reference counts for each of 65K possible ports for each
of 4 NAT protocols. Totalling 1MB per address. Wow.
A close read of the code shows that an "is used" check
precedes each attempted reference count increment.
That means the refcount never actually gets above 1.
That in turn means algorithmically, a bit vector is
sufficient. And one need not be allocated for more
than the highest validated port referenced.
These changes introduce a dynamically sized bit vector
replacing the reference counts, for a maximum of 32K
if all 4 protocols use port 65535. In fact, protocol
OTHER is never used, so at most 24K will be used, and
none of it will be "statically" allocated per address.

We validate each descriptor via memif_validate_desc_data and set
desc_status to non-zero for the corresponding descriptor when
the descriptor is bad. However, desc_status is not propagated back to
xor_status in memif_validate_desc_data which eventually sets
ptd->xor_status.
Not setting ptd->xor_status causes us to treat all descriptors as
"simple". In that case, when we try to copy also the bad descriptors to
the buffers, it results a crash since desc_data is not set to point
to the correct memory in the descriptor.
The fix is to set xor_status in memif_validate_desc_data such that if
there is a bad descriptor in the frame, "is_simple" is set to false and
we have to selectively copy only the good descriptors to the buffers.

Type: fix
After peers roaming support addition, FIB entry tracking stopped
working. For example, it can be observed when an adjacency is stacked on
a FIB entry by the plugin and the FIB entry hasn't got ARP resolution
yet. Once the FIB entry gets ARP resolution, the adjacency is not
re-stacked as it used to. This results in endless ARP requests when a
traffic is sent via the adjacency.
This is broken because the plugin stopped using "midchain delegate" with
peers roaming support addition. The reason is that "midchain delegate"
didn't support stacking on a different FIB entry which is needed when
peer's endpoint changes. Now it is supported there (added in 36892).
With this fix, start using "midchane delegate" again and thus, fix FIB
entry tracking. Also, cover this in tests.

Currently, once an adjacency is stacked on a FIB entry via
adj_midchain_delegate_stack(), "midchain delegate" is created for the
adjacency and the FIB index is stored there. And all further calls to
adj_midchain_delegate_stack() even passing another FIB index will cause
the function to still use the stored one. In other words, there is
currently no way to stack an adjacency on another FIB index if "midchain
delegate" already exists for it.
Being able to stack on another FIB index is needed for the wireguard
plugin. As per the protocol, peers can roam between different external
endpoints. When an authenticated packet is received and it was sent from
a different endpoint than currently stored, the endpoint needs to be
updated and all futher communication needs to happen with that endpoint.
Thus, the corresponding to that peer adjacencies need to be stacked on
the FIB entry that corresponds to the new endpoint.
With this change, add adj_midchain_delegate_remove() that removes
"midchain delegate". When stacking on another FIB entry is needed,
existing "midchain delegate" can be removed and then, a new one created
with a new FIB index via adj_midchain_delegate_stack().

In several NAT submodules, the number of available ports (0xffff - 1024)
may not be divisible by the number of workers, so port_per_thread is
determined by integer division, which is the floor of the quotient.
Later when a worker index is needed, dividing the port with port_per_thread
may yield an out-of-bound array index into the workers array.
As an example, assume 2 workers are configured, then port_per_thread
will be (0xffff - 1024) / 2, which is 32255. When we compute a worker
index with port 0xffff, we get (0xffff - 1024) / 32255, which is 2,
but since we only have 2 workers, only 0 and 1 are valid indices.
This patch fixes the problem by adding a modulo at the end of the division.

This patch enables statistics from the Arm PMUv3 through the perfmon
plugin.
In comparison to using the Linux "perf" tool, it allows obtaining
direct, per node level statistics (rather than per thread). By accessing
the PMU counter registers directly from userspace, we can avoid the
overhead of using a read() system call and get more accurate and fine
grained statistics about the running of individual nodes.
A demo of perfmon on Arm can be found at:
https://asciinema.org/a/egVNN1OF7JEKHYmfl5bpDYxfF
*Important Note*
Perfmon on Arm is dependent on and works only on Linux kernel versions
of v5.17+ as this is when userspace access to Arm perf counters was
included.
On most Arm systems, a maximum of 7 PMU events can be configured at once
- (6x PMU events + 1x CPU_CYCLE counter). If some perf counters are in
use elsewhere by other applications, and there are insufficient counters
remaining to open the bundle, the perf_event_open call will fail
(provided the events are grouped with the group_fd param, which perfmon
currently utilises).
See arm/events.h for a list of PMUv3 events available, although it is
implementation defined whether most events are implemented or not. Only
a small set of 7 events is required to be implemented in Armv8.0, with
some additional events required in later versions. As such, depending on
the implementation, some statistics may not be available. See Arm
Architecture Reference Manual for Armv8-A, D7.10.2 "The PMU event number
space and common events" for more information.
arm/events.c:arm_init() gets information from the sysfs about what
events are implemented on a particular CPU at runtime. Arm's
implementation of the perfmon source callback .bundle_support uses this
information to disable unsupported events in a bundle, or in the case
no events are supported, disable the entire bundle.
Where a particular event in a bundle is not implemented, the statistic
for that event is shown as '-' in the 'show perfmon statistics' cli
output, by disabling the column.
There is additional code in perfmon.c to only open events which are
marked as implemented. Since we're only opening and reading events that
are implemented, some extra logic is required in cli.c to re-align
either perfmon_node_stats_t or perfmon_reading_t with the column
headings configured in each bundle, taking into account disabled
columns.
Userspace access to perf counters is disabled by default, and needs to
be enabled with 'sudo sysctl kernel/perf_user_access=1'.
There is a check built into the Arm event source init function
(arm/events.c:arm_init) to check that userspace reading of perf counters
is enabled in the /proc/sys/kernel/perf_user_access file.
If the above file does not exist, it means the kernel version is
unsupported. Users without a supported kernel will see a warning
message, and no Arm bundles will be registered to use in perfmon.
Enabling/using plugin:
- include the following in startup.conf:
- plugins { plugin perfmon_plugin.so { enable }
- 'show perfmon bundle [verbose]' - show available statistics bundles
- 'perfmon start bundle <bundle-name>' - enable and start logging
- 'perfmon stop' - stop logging
- 'show perfmon statistics' - show output
For a general guide on using and understanding Arm PMUv3 events, see

In preparation for enabling perfmon on Arm platforms, move some Intel
/arch specific logic into the /intel directory and update the CMake to
split the common code from arch specific files.
Since the dispatch_wrapper code is very different on Arm/Intel,
each arch can provide their own implementation + conduct any additional
arch specific config e.g. on Intel, all indexes from the mmap pages are
cached. The new method intel_config_dispatch_wrapper conducts this
config and returns a pointer to the dispatch wrapper to use.
Similarly, is_bundle_supported() looks very different on Arm/Intel, so
each implementation is to provide their own arch specific checks.
Two new callbacks/function ptrs are added in PERFMON_REGISTER_SOURCE to
support this - .bundle_support and .config_dispatch_wrapper.

classify hash used to be stored as u64 in buffer metadata, use 32 bits
instead:
- on almost all our supported arch (x86 and arm64) we use crc32c
intrinsics to compute the final hash: we really get a 32-bits hash
- the hash itself is used to compute a 32-bits bucket index by masking
upper bits: we always discard the higher 32-bits
- this allows to increase the l2 classify buffer metadata padding such
as it does not overlap with the ip fib_index metadata anymore. This
overlap is an issue when using the 'set metadata' action in the ip

This patch introdcues basic types supporting fast path lookup.
Fast path performs policy matching with use of hash lookup
(particularly bihash tries has been used for that purpose). Fast path
lookup addresses situation where huge number of policies is created
(~100k or more). In such scenario adding/removing a policy
and policy matching is not efficient and poorly scales (for example
adding 500k policies takes a few hours. Also lookup time
increases significantly). With fast path adding and matching up to
1M flows scales up linearly (adding 1M of policies takes about 150s
on the test machine vs many hours in case of original implementation,
also matching time is significantly improved). Fast path will not
deal well with a huge number of policies that are spanning large
ip/port ranges. Large range will be masked out almost entirely leaving
only a few bits for calculating the hash key. Such keys will tend to
gather much more policies than other keys and hash will match most of
the packets anihilating advantages of hashing. Having said that
we also think that it is not the real life scenario.

Issue:
Let iperf3 server run via ldp and vcl on top of vpp's host stack. If
iperf3 client connects this iperf3 server with tcp MSS setting option,
iperf3 server will always crash.
Root cause:
When MSS option is specified by iperf3 client, iperf3 server will
recreate the listening socket firstly, then call setsockopt() to set MSS
immediately. Iperf3 code can be referred here:
58332f8154/src/iperf_tcp.c (L186).
However, in vcl layer vpp_evt_q of this recreated session is not
allocated yet. So iperf3 server crashes with vpp_evt_q null pointer access.
Fix:
Add session vpp_evt_q null pointer check in vcl_session_transport_attr().

Currently, neighbor adjacencies on a wg interface are converted into a
midchain only if one of the peers has a matching allowed prefix
configured. If create a route that goes through a wg interface but the
next-hop address does not match any allowed prefixes, an ARP/ND request
will try to be sent via the wg interface to resolve the next-hop address
when matching traffic occurs. And sending an ARP request will cause VPP
to crash while copying hardware address of the wg interface which is
NULL. Sending an ND message will not cause VPP to crash but the error
logged will be unclear (no source address).
With this fix, convert all neighbor adjacencies on a wg interface into a
midchain and update tests to cover the case. If there is no matching
allowed prefix configured, traffic going such routes will be dropped
because of "Peer error". No changes if there is matching allowed prefix
configured.
Also, fix getting peer by adjacency index.

However, when no template_send is needed, template_bi is ~0.
When this happens, no vectors are placed in the frame. When
the frame is then "put", a check for n_vectors == 0 prevents
the frame from actually being placed back on the free list.
Fix that by using a direct call to vlib_frame_free() when

A node name is not bound to a node index. For example, if an interface
is deleted and re-added, the indexes of its nodes "<itfc_name>-tx"
and "<itfc_name>-output" may change. Thus, when the collector updates
the nodes stats, it should first delete all the symlinks for nodes that
have changed their names before adding new symlinks. Otherwise, it
could attempt to add already existing symlinks or delete valid ones.
Example of a series of command that triggers a crash in the assert
`ASSERT (node_data[i].symlinks[j] != CLIB_U32_MAX);`:
```
create loopback interface
create loopback interface
```
Wait for the nodes stats to update, then:
```

delete loopback interface intfc loop1

link_speed equal 0xFFFFFFFF(UINT32_MAX) by 1000, this provides
overflow of unsigned int, and as result link_speed was equal
4295 Gbps, but actually link_speed is unknown.

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)

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.

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.

interfaces is kept.
Configuration gives you the ability to change default behavior
to direct or restrict traffic between different FIB tables.
NAT specific VRF routing options:
a) keeping communication in the same VRF
b) option to add multiple destination VRFs
c) option to control the resolution order of destination VRFs
TX FIB resolution is based on looking up RX FIB entry in NATs
VRF table and picking the first FIB that resolves

Currently, the plugin can monitor link state changes on hardware
interfaces for which a linux-cp pair exists. When the link goes down on
one of the hardware interfaces, the plugin processes IPv4 routes that
resolve through that interface according to the configurations:
del-static-on-link-down and del-dynamic-on-link-down.
The problem is that link state changes are not signaled for
subinterfaces and the code that handles IPv4 routes is not triggered.
When the link on a hardware interface goes down, it implies
that subinterfaces added to that interface also will have the link in
the down state.
With this change, when the link goes down on a hardware interface,
iterate over subinterfaces added to the interface and apply the same
logic of routes processing as for hardware interfaces.

lcp_router_table_flush() is used to remove routes from the given route
table if they are resolved through the given interface with specified
FIB source. Currently, if you need to remove routes from a route table
that are resolved through one of the interfaces from a vector, the
function has to be executed for every interface from the vector. Every
execution walks the route table again.
With this change, lcp_router_table_flush() accepts a vector of
interfaces. Thus, the function can walk a single route table once and
delete routes that resolve through one of the interfaces from the
vector.

Currently, when the link goes down on an interface, routes that resolve
through that interface and created with Nexthop API are removed by the
kernel. However, IPv4 routes remain in the FIB because the kernel
doesn't send any notifications about that.
And for the plugin working with user-space applications that create
routes in the kernel using Nexthop API there should be a mechanism to
synchronize the FIB and the kernel in this case.
With this change, add two new startup configuration options to the
plugin to be able to control what should happen with static and dynamic
routes managed by the plugin on link down:
- del-static-on-link-down (disabled by default, delete routes created
with the linux-cp static FIB source on link down),
- del-dynamic-on-link-down (disabled by default, delete routes created
with the linux-cp dynamic FIB source on link down).
Then, monitor link state changes on interfaces for which a linux-cp pair
exists. If the link goes down on one of the interfaces, process routes
that resolve through that interface according to the new configurations.

In order to support the requirement of RSS and packet steering of new
protocols, such as GTPU PDU-type and QFI, for 5G UPF, a generic pattern
is introduced in vnet flow. The generic flow pattern is based on DDP
(Dynamic Device Personalization) function and Parser Library module in
DPDK. Using generic flow pattern, we do not need to create new packet
and field type and offset in API parser for every new protocols. We can
create flows for any protocol immediately as long as supported by DDP.
The generic flow can be used to support 5G related protocols in
different scenarios.
The input of this generic pattern are two binary strings for spec and
mask. Spec is the binary presentation of the target packet type, and
mask is used to mark the target fields.
In this patch DPDK plugins is enabled for POC. Next step we will enable
generic flow in native IAVF, which is the main target.
Here is an example. If we want to create a flow for GTPU QFI,
spec is:
00000000000100000000000208004500003C00000000001100000101010102020202000

01010102020202
mask is:
00000000000000000000000000000000000000000000000000000000000000000000000

A naming API POC is created via VAPI to help create the rule with

code when clib_longjump is called and that results in wrong return

While setting an ACL, a user can specify the adjacency to follow after
the input ACL node. Thus, we may skip a lookup and enter directly a
local node (ex: ip4_local). To prevent the local source check from
failing, we need to specify the fib index. And, we have to do it just
before exiting the input ACL node because the l2_classify object
is overlapping with the fib_index in the vnet_buffer_opaque_t struct.
We could have added a padding to avoid this overlap but there is no
place for that in the structure.

Type: fix
Currently, a tap interface created to be a member of a linux-cp pair has
default link state (down) and default link speed (10Mb/s). Then the
plugin monitors the link state of the paired hardware interface and if
it changes, the new link state is reflected on the tap interface. And
when the new link state is "up", the link speed is also reflected on the
tap interface.
The problem is that this scheme implies that the hardware interface's
link state is "down" at the moment of the linux-cp pair creation and
then changes. But there are cases when the link state is already "up" at
that moment. If that is the case, the link speed on the tap interface
will remain the default one until the link comes down and then comes up.
With this fix, when a linux-cp pair is created, reflect current link
state of the hardware interface being paired on the created tap
interface.

When a VRRP advertisement is received by a worker thread, the worker
calls vl_api_rpc_call_main_thread() so the main thread will process the
packet and make adjustments to VR state if necessary.
The data being passed to the main thread included a pointer to the VRRP
header in the received packet buffer. Since the main thread processes
the RPC request asynchronously from the worker thread, it's possible for
the worker to drop the packet and for the buffer to be overwritten before
the main thread can process it.
Copy the fields which may be needed by the main thread into a struct
instead of passing a pointer to a packet buffer.

Add support for inline packet counter verification to send_and_* functions.
Diff dictionary is a dictionary of dictionaries of interesting stats:
diff_dictionary =
{
"err" : { '/error/counter1' : 4, },
sw_if_index1 : { '/stat/segment/counter1' : 5,
'/stat/segment/counter2' : 6,
},
sw_if_index2 : { '/stat/segment/counter1' : 7,
},
}
It describes a per sw-if-index diffset, where each key is stat segment
path and value is the expected change for that counter for sw-if-index.
Special case string "err" is used for error counters.
This then allows more precise packet counter verification by first
defining a "zero" dictionary, e.g. for ED NAT:
cls.no_diff = StatsDiff({
pg.sw_if_index: {
'/nat44-ed/in2out/fastpath/tcp': 0,
'/nat44-ed/in2out/fastpath/udp': 0,
'/nat44-ed/in2out/fastpath/icmp': 0,
'/nat44-ed/in2out/fastpath/drops': 0,
'/nat44-ed/in2out/slowpath/tcp': 0,
'/nat44-ed/in2out/slowpath/udp': 0,
'/nat44-ed/in2out/slowpath/icmp': 0,
'/nat44-ed/in2out/slowpath/drops': 0,
'/nat44-ed/in2out/fastpath/tcp': 0,
'/nat44-ed/in2out/fastpath/udp': 0,
'/nat44-ed/in2out/fastpath/icmp': 0,
'/nat44-ed/in2out/fastpath/drops': 0,
'/nat44-ed/in2out/slowpath/tcp': 0,
'/nat44-ed/in2out/slowpath/udp': 0,
'/nat44-ed/in2out/slowpath/icmp': 0,
'/nat44-ed/in2out/slowpath/drops': 0,
}
for pg in cls.pg_interfaces
})
and then to specify only changed counters directly when calling
one of send_and_* functions:
self.send_and_assert_no_replies(
self.pg0, pkts, msg="i2o pkts",
stats_diff=self.no_diff | {
"err": {
'/err/nat44-ed-in2out-slowpath/out of ports': len(pkts),
},
self.pg0.sw_if_index: {
'/nat44-ed/in2out/slowpath/drops': len(pkts),
},
}
)
operator | is overloaded by StatsDiff class to perform a deep merge operation,
so in above case, dictionaries for "err" and self.pg0.sw_if_index do not
overwrite whole sub-dictionaries, rather the contents are merged,
assuring that all the remaining counters are verified to be zero.

When the adj subsystem is notified of a BFD session, it attempts to find the appropriate adjacency from the session's key.
This could lead to a mismatch between the adj used by BFD and that of FIB. The BFD session stores the adj it is using, so FIB uses that instead.
Since adj is now using the same adj as BFD, it does not need to maintain its own locks.
In BFD it is necessary to initialise the adj index used in INVALID and ensure it is not unlock before listeners are notified of the session delete.

The BFD delayed auth change test was failing intermittently within CI.
Debugging has shown it depends on the initial random seed, e.g. the below
will consistently fail:
RND_SEED=1643734669.7126195 TEST='bfd.BFDAuthOnOffTestCase.test_auth_change_key_delayed'
Same thing will happen with:
RND_SEED=1643736595.1363552
RND_SEED=1643722239.8224792
The analysis of the behavior shown that the function that is doing the hash verification,
modifies the content of the packet for the purposes of hash computation.
In case of the auth rollover, this function may be called twice - resulting in the second
comparison to be made with a bogus packet data, thus failing the check and the test.
The above values of random seed are the ones where the test makes it
to the point of this double comparison.
The solution is to restore the data within the packet after the check from the array
where we have copied it into before modifying the packet.

Implement proper state machine based on above RFCs. ACKs to SYNs/FINs
are no longer required/tracked. This is more friendly to peers and
accounts for lost packets and retransmits.
This change also means that all traffic is translated and forwarded
while in transitory timeout, which helps delivering e.g. retransmitted
FINs, FINACKs and other messages.
Also support reopening a session in transitory timeout after seeing both
FINs by seeing both SYNs again. This helps quick connection
reestablishment if the peers want to.
