With this patch fast path for ipv6 policy lookup is enabled.
This impelentation scales and outperforms original implementation when
the number of defined flows is higher thatn 100k.

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.

0 is not NULL (at least not in all cases), passing 0 into a variadic
function in a place where the consumer reads it as pointer might
leave parts of the pointer uninitilized and hence filled with random
data.
It seems that this used to work with gcc, but clang seems to treat the
0 in those places as a 32bit integer.

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
ACL node which updates both fields

This patch introduces ipsec_output.h file. Matching implementation is

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.

Currently 0 has been used as the wildcard representing ANY type of
protocol. However 0 is valid value of ip protocol (HOPOPT) and therefore
it should not be used as a wildcard. Instead 255 is used which is

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:
https://github.com/esnet/iperf/blob/58332f8154e2140e40a6e0ea060a418138291718/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().
Add a vcl test case for this MSS option scenario.

set interface ip address loop0 10.0.0.1/32
set interface state GigabitEthernet3/0/1 up
set interface state loop0 up
set interface state loop0 down
set interface ip address del loop0 10.0.0.1/32
delete loopback interface intfc loop0
set interface state GigabitEthernet3/0/1 down
set interface state GigabitEthernet3/0/1 up
comment { the following crashes VPP }
set interface state GigabitEthernet3/0/1 down
This sequence reliably crashes VPP:
(gdb)p n->name
$4 = (u8 *) 0x7fff82b47578 "interface-3-output-deleted”
If the interface doesn't exist, return ~0 and be tolerant of this in the
