Coverify complains deref_ptr before null check.
deref_ptr: Directly dereferencing pointer reg.
1214 vl_reg = vl_api_client_index_to_registration (reg->client_index);
1215 ALWAYS_ASSERT (vl_reg != NULL);
1216
CID 216104 (#1 of 1): Dereference before null check (REVERSE_INULL)
check_after_deref: Null-checking reg suggests that it may be null, but it
has already been dereferenced on all paths leading to the check.
1217 if (reg && vl_api_can_send_msg (vl_reg))
I believe the check is for vl_reg instead of reg because vl_reg may be NULL
after the call vl_api_client_index_to_registration.

When a buffer is freed and re-allocated for a new packet, opaque2 is
not reset, so the offload flags can be set to a stale value.
Make sure the offload flags are reset to the current value on 1st set.

Type: refactor
This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.
This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.

Support setting the MTU for a peer on an interface. The minimum value of
the path and interface MTU is used at forwarding time.
the path MTU is specified for a given peer, by address and table-ID.
In the forwarding plane the MTU is enfored either:
1 - if the peer is attached, then the MTU is set on the peer's
adjacency
2 - if the peer is not attached, it is remote, then a DPO is added to
the peer's FIB entry to perform the necessary fragmentation.

The policer code uses a naming convention of prefixing a lot of
its definitions with "SSE2" when in fact there is nothing SSE2
specific about them. This is confusing so remove the prefix.
Unfortunately it has to stay in the API definitions for backward
compatibility.

If the multi-worker default VPP configuration is triggered by

It's a substantial number, so this change marks all of the

Avoid doing inter-thread reads without locks by doing a handoff before
destination address rewrite. Destination address is read from a session
which is possibly owned by a different thread. By splitting the work in
two parts with a handoff in the middle, we can do both in a thread safe
way.

Running vpp without any interface configured and then invoking the
binary-api l2_xconnect_dump causes vpp to crash in l2_input_is_xconnect due
to l2input_main.configs has no memory allocated to it, not even for the local
interface which exists all the times.
The reason that l2input_main.configs has no memory allocated to it was due to
gerrit patch 29232 which took out a line in l2input_init
/* Create the config vector */
vec_validate (mp->configs, 100);
The fix is to iterate through l2input_main.configs for each interface in
l2 to call l2_input_is_xconnect when dumping l2_xconnect interfaces.

Sometimes, vnet_hw_if_rx_queue_set_int_pending is called on rxqs which
are not in interrupt mode. Currently, it segfaults due to a too small
clib_interrupt_t structure. This change prevents that and makes the
framework slightly more robust to driver bugs (that might be subtle
to track in some cases involving concurrency...)

A NAT sub-plugin doing statically configured match/rewrite on IP4 input or output.
It's stateless (no connection tracking).
Currently it supports rewriting of SA, DA and TCP/UDP ports.
It should be simple to add new rewrites if required.
API:
pnat_binding_add, pnat_binding_del, pnat_bindings_get, pnat_interfaces_get
CLI:
set pnat translation interface <name> match <5-tuple> rewrite <5-tuple> {in|out} [del]
show pnat translations
show pnat interfaces
Trying a new C based unit testing scheme. Where the graph node is tested
in isolation. See pnat/pnat_test.c.
Also added new cmake targets to generate coverage directly.
E.g.:
make test_pnat-ccov-report
