03c0ef95cb bonding: process lacp when bond is admin down
Ticket: VPP-1821
Type: fix
Fixes: 6dfd3785e4

When a bond interface is administratively down but the slaves are
up, process inbound LACP packets received over the slaves. This
was the old behavior with bond interfaces in LACP mode and was
altered unintentionally by another change. Restore the old behavior.

c385a95e8e api: mark api_trace_command_fn thread-safe
Binary API trace replay with multiple worker threads depends in many
cases on worker thread graph replica maintenance. If we (implicitly)
assert a worker thread barrier at the debug CLI level, all graph
replica changes are deferred until the replay operation completes. If
an interface is deleted, the wheels may fall off.

257749c409 fib: FIB crash removing labelled route (VPP-1818)
Type: fix

The crash occured trying to retreive a NULL path list to walk the path
extensions. A walk shoul not be required, because there should be no
extensins, since all paths are removed. The problem is that when the
paths were added, they were not sorted, hence neither were the
extensions and when they were updated, duplicate extensions were added,
and hence a path removal did not remove them all.
Fix is to make sure paths are sorted.

d0bb569621 vxlan: reuse inner packet flow hash for tunnel outer header load balance
Type: fix

Several tunnels encapsulation use udp as outer header and udp src port
is set by inner header flow hash, such as gtpu, geneve, vxlan, vxlan-gbd
Since flow hash of inner header is already been calculated, keeping it
to vnet_buffere[b]->ip.flow_hash should save load-balance node work to
select ECMP uplinks.

814e898eba vxlan: fix vxlan hw offload issue
Type: fix

Since Vxlan hw offload jumps the ethernet-input node, so needs to
adjust the data offset accordingly

In original code, the current_data is 0 when arriving vxlan-flow-input
node(due to no graph node before it, except the dpdk-input), so this
code block cannot find the correct vxlan header:
enum
  { payload_offset = sizeof (ip4_vxlan_header_t) };
vlib_buffer_advance (b0, payload_offset);
see code in src/vnet/vxlan/decap.c, function vxlan4_flow_input_node

This patch fixes this issue

- Fix AAD initialization. With use-esn the aad data consists of the SPI
and the 64-bit sequence number in big-endian order. Fix the u32 swapped
code.

- Remove salt-reinitialization. The GCM code seems inspired by the GCM
RFCs recommendations on IKE keydata and how to produce a salt
value (create an extra 4 octets of keying material). This is not IKE
code though and the SA already holds the configured salt value which
this code is blowing away. Use the configured value instead.

93feaa2fff tests: make threads in punt tests join when finished
The 42693521f6046997133c8f63bcfc9d615d96f69d added the timeout
to the child process join + print the name of the offending
child process.

Upon testing the issue furher, appeared the offenders were
always the same - punt tests. The processes running them
were stuck trying to acquire lock, even if all
the user-accessible execution has finished. Some searching
revealed that one needs to tread carefully when dealing
with Thread and Multiprocessing at the same time.

punt tests used threads but did not call thread.join. Somehow
it worked in some cases but not the others. This fix makes
the threads exit cleanly - which also makes the timeouts
waiting for the process to join disappear.

7f9603d90a tests: avoid test runner hanging on child test process join
In parallel test, the single process is spawning
a bunch of child processes running the tests,
and communicates to them. When the child process
signals that it has finished, the parent calls
child.join(). Sometimes this join never returns.
The result is a lot of defunct python processes,
and the test run just hangs.

I have seen this failure intermittently a fair bit
in a busy containerized environment, and by chance,
consistently reproduced it on a Thinkpad X280
with 8G of RAM and Ubuntu 19.04, which allowed
to diagnose it.
