Audit tests count the total number of messages sent and compares
with total number of CMSG received on error queue. Example:
udp gso zerocopy timestamp audit
udp rx: 1599 MB/s 1166414 calls/s
udp tx: 1615 MB/s 27395 calls/s 27395 msg/s
udp rx: 1634 MB/s 1192261 calls/s
udp tx: 1633 MB/s 27699 calls/s 27699 msg/s
udp rx: 1633 MB/s 1191358 calls/s
udp tx: 1631 MB/s 27678 calls/s 27678 msg/s
Summary over 4.000 seconds...
sum udp tx: 1665 MB/s 82772 calls (27590/s) 82772 msgs (27590/s)
Tx Timestamps: 82772 received 0 errors
Zerocopy acks: 82772 received
Errors are thrown if CMSG count does not equal send count,
example:
Summary over 4.000 seconds...
sum tcp tx: 7451 MB/s 493706 calls (123426/s) 493706 msgs (123426/s)
./udpgso_bench_tx: Unexpected number of Zerocopy completions: 493706 expected 493704 received

overall test time does not increase significantly.

This enhancement adds options that facilitate load testing with
additional TX CMSG options, and to optionally print results of
various send CMSG operations.
These options are especially useful in isolating situations
where error-queue messages are lost when combined with other
CMSG operations (e.g. SO_ZEROCOPY).
New options:
-a - count all CMSG messages and match to sent messages
-T - add TX CMSG that requests TX software timestamps
-H - similar to -T except request TX hardware timestamps
-P - call poll() before reading error queue
-v - print detailed results
v2: Enhancements as per Willem de Bruijn <willemb@google.com>
- Updated control and buffer parameters for recvmsg
- poll() parameter cleanup
- fail on bad audit results
- remove TOS options
- improved reporting

- add SOF_TIMESTAMPING_OPT_TSONLY to eliminate MSG_TRUNC

sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2,
otherwise the bc packets from $rp2 won't be forwarded. This patch is to
add this setting for $rp2.
Also, as ping_test_from does grep "$from" only, which could match some
unexpected output, some test case doesn't really work, like:
# ping_test_from $h2 198.51.200.255 198.51.200.2
PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data.
64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms
When doing grep $form (198.51.200.2), the output could still match.
So change to grep "bytes from $from" instead.

In the pmtu_vti6_link_change_mtu test, both local and remote addresses
for the vti6 tunnel are assigned to the same address given to the dummy
interface that we use as encapsulating device with a known MTU.
This works as long as the dummy interface is actually selected, via
rt6_lookup(), as encapsulating device. But if the remote address of the
tunnel is a local address too, the loopback interface could also be
selected, and there's nothing wrong with it.
This is what some older -stable kernels do (3.18.z, at least), and
nothing prevents us from subtly changing FIB implementation to revert
back to that behaviour in the future.
Define an IPv6 prefix instead, and use two separate addresses as local
and remote for vti6, so that the encapsulating device can't be a
loopback interface.

I was really surprised that the IPv6 mtu exception followed by redirect
test was passing as nothing about the code suggests it should. The problem
is actually with the logic in the test script.
Fix the test cases as follows:
1. add debug function to dump the initial and redirect gateway addresses
for ipv6. This is shown only in verbose mode. It helps verify the
output of 'route get'.
2. fix the check_exception logic for the reset case to make sure that
for IPv4 neither mtu nor redirect appears in the 'route get' output.
For IPv6, make sure mtu is not present and the gateway is the initial
R1 lladdr.
3. fix the reset logic by using a function to delete the routes added by
initial_route_*. This format works better for the nexthop version of
the tests.
While improving the test cases, go ahead and ensure that forwarding is
disabled since IPv6 redirect requires it.
Also, runs with kernel debugging enabled sometimes show a failure with
one of the ipv4 tests, so spread the pings over longer time interval.
The end result is that 2 tests now show failures:
TEST: IPv6: mtu exception plus redirect [FAIL]
and the VRF version.
This is a bug in the IPv6 logic that will need to be fixed
separately. Redirect followed by MTU works because __ip6_rt_update_pmtu
hits the 'if (!rt6_cache_allowed_for_pmtu(rt6))' path and updates the
mtu on the exception rt6_info.
MTU followed by redirect does not have this logic. rt6_do_redirect
creates a new exception and then rt6_insert_exception removes the old
one which has the MTU exception.

The SO_TXTIME API enables packet tranmission with delayed delivery.
This is currently supported by the ETF and FQ packet schedulers.
Evaluate the interface with both schedulers. Install the scheduler
and send a variety of packets streams: without delay, with one
delayed packet, with multiple ordered delays and with reordering.
Verify that packets are released by the scheduler in expected order.
The ETF qdisc requires a timestamp in the future on every packet. It
needs a delay on the qdisc else the packet is dropped on dequeue for
having a delivery time in the past. The test value is experimentally
derived. ETF requires clock_id CLOCK_TAI. It checks this base and
drops for non-conformance.
The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP
as of commit fb420d5d91 ("tcp/fq: move back to CLOCK_MONOTONIC").
Within a flow there is an expecation of ordered delivery, as shown by
delivery times of test 4. The FQ qdisc does not require all packets to
have timestamps and does not drop for non-conformance.
The large (msec) delays are chosen to avoid flakiness.
Output:
SO_TXTIME ipv6 clock monotonic
payload:a delay:28 expected:0 (us)
SO_TXTIME ipv4 clock monotonic
payload:a delay:38 expected:0 (us)
SO_TXTIME ipv6 clock monotonic

The point of the pause-on-fail argument is to leave the setup as is after
a test fails to allow a user to debug why it failed. Move the cleanup
after posting the result to the user to make it so.
Random names for the namespaces are not user friendly when trying to
debug a failure. Make them simpler and more direct for the tests. Run
cleanup at the beginning to ensure they are cleaned up if they already
exist.
Remove cleanup_done. There is no harm in doing cleanup twice; just
ignore any errors related to not existing - which is already done.

As all the testing addresses are in the same subnet and egress device ==
ingress device. We need enable forwarding to get the route entry.
Also disable rp_filer separately as some distributions enable it in

With the model where dev is represented by devlink and ports are
represented by devlink ports, make debugfs file names independent
on netdev names. Change the topology to the one illustrated
by the following example:
$ ls /sys/kernel/debug/netdevsim/
netdevsim1
$ ls /sys/kernel/debug/netdevsim/netdevsim1/
bpf_bind_accept bpf_bind_verifier_delay bpf_bound_progs ports
$ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/
0 1
$ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/0/
bpf_map_accept bpf_offloaded_id bpf_tc_accept bpf_tc_non_bound_accept bpf_xdpdrv_accept bpf_xdpoffload_accept dev ipsec
$ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/0/dev -l

pmtu.sh script runs a number of tests and dumps a summary of pass/fail.
If a test fails, it is near impossible to debug why. For example:
TEST: ipv6: PMTU exceptions [FAIL]
There are a lot of commands run behind the scenes for this test. Which
one is failing?
Add a VERBOSE option to show commands that are run and any output from
those commands. Add a PAUSE_ON_FAIL option to halt the script if a test
fails allowing users to poke around with the setup in the failed state.
In the process, rename tracing to TRACING and move declaration to top
with the new variables.
