This is a sloppy logic analyzer using GPIOs. It comes with a script to
isolate a CPU for polling. While this is definitely not a production
level analyzer, it can be a helpful first view when remote debugging.

Pablo Neira Ayuso says:
====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for net-next:
Patch #1 to #11 to shrink memory consumption for transaction objects:
struct nft_trans_chain { /* size: 120 (-32), cachelines: 2, members: 10 */
struct nft_trans_elem { /* size: 72 (-40), cachelines: 2, members: 4 */
struct nft_trans_flowtable { /* size: 80 (-48), cachelines: 2, members: 5 */
struct nft_trans_obj { /* size: 72 (-40), cachelines: 2, members: 4 */
struct nft_trans_rule { /* size: 80 (-32), cachelines: 2, members: 6 */
struct nft_trans_set { /* size: 96 (-24), cachelines: 2, members: 8 */
struct nft_trans_table { /* size: 56 (-40), cachelines: 1, members: 2 */
struct nft_trans_elem can now be allocated from kmalloc-96 instead of
kmalloc-128 slab.
Series from Florian Westphal. For the record, I have mangled patch #1
to add nft_trans_container_*() and use if for every transaction object.
I have also added BUILD_BUG_ON to ensure struct nft_trans always comes
at the beginning of the container transaction object. And few minor
cleanups, any new bugs are of my own.
Patch #12 simplify check for SCTP GSO in IPVS, from Ismael Luceno.
Patch #13 nf_conncount key length remains in the u32 bound, from Yunjian Wang.
Patch #14 removes unnecessary check for CTA_TIMEOUT_L3PROTO when setting
default conntrack timeouts via nfnetlink_cttimeout API, from
Lin Ma.
Patch #15 updates NFT_SECMARK_CTX_MAXLEN to 4096, SELinux could use
larger secctx names than the existing 256 bytes length.
Patch #16 adds a selftest to exercise nfnetlink_queue listeners leaving
nfnetlink_queue, from Florian Westphal.
Patch #17 increases hitcount from 255 to 65535 in xt_recent, from Phil Sutter.

Add a protocol spec for tcp_metrics, so that it's accessible via YNL.
Useful at the very least for testing fixes.
In this episode of "10,000 ways to complicate netlink" the metric
nest has defines which are off by 1. iproute2 does:
struct rtattr *m[TCP_METRIC_MAX + 1 + 1];
parse_rtattr_nested(m, TCP_METRIC_MAX + 1, a);
for (i = 0; i < TCP_METRIC_MAX + 1; i++) {
// ...
attr = m[i + 1];
This is too weird to support in YNL, add a new set of defines
with _correct_ values to the official kernel header.

This implements what I was describing in [1]. When writing a test
author can schedule cleanup / undo actions right after the creation
completes, eg:
cmd("touch /tmp/file")
defer(cmd, "rm /tmp/file")
defer() takes the function name as first argument, and the rest are
arguments for that function. defer()red functions are called in
inverse order after test exits. It's also possible to capture them
and execute earlier (in which case they get automatically de-queued).
undo = defer(cmd, "rm /tmp/file")
# ... some unsafe code ...
undo.exec()
As a nice safety all exceptions from defer()ed calls are captured,
printed, and ignored (they do make the test fail, however).
This addresses the common problem of exceptions in cleanup paths
often being unhandled, leading to potential leaks.
There is a global action queue, flushed by ksft_run(). We could support
function level defers too, I guess, but there's no immediate need..

We cannot use CLONE_VFORK because we also need to wait for the timeout
signal.
Restore tests timeout by using the original fork() call in __run_test()
but also in __TEST_F_IMPL(). Also fix a race condition when waiting for
the test child process.
Because test metadata are shared between test processes, only the
parent process must set the test PID (child). Otherwise, t->pid may be
set to zero, leading to inconsistent error cases:
# RUN layout1.rule_on_mountpoint ...
# rule_on_mountpoint: Test ended in some other way [127]
# OK layout1.rule_on_mountpoint
ok 20 layout1.rule_on_mountpoint
As safeguards, initialize the "status" variable with a valid exit code,
and handle unknown test exits as errors.
The use of fork() introduces a new race condition in landlock/fs_test.c
which seems to be specific to hostfs bind mounts, but I haven't found
the root cause and it's difficult to trigger. I'll try to fix it with
another patch.

The mirroring tests are currently run in a skip_hw and optionally a skip_sw
mode. The former tests the SW datapath, the latter the HW datapath, if
available. In order to be able to test SW datapath on HW loopbacks, traps
are installed on ingress to get traffic from the HW datapath to the SW one.
This adds an unnecessary complexity when it would be much simpler to just
use a veth-based topology to test the SW datapath. Thus drop all the code
that supports this dual testing.

The mirroring selftests work by sending ICMP traffic between two hosts.
Along the way, this traffic is mirrored to a gretap netdevice, and counter
taps are then installed strategically along the path of the mirrored
traffic to verify the mirroring took place.
The problem with this is that besides mirroring the primary traffic, any
other service traffic is mirrored as well. At the same time, because the
tests need to work in HW-offloaded scenarios, the ability of the device to
do arbitrary packet inspection should not be taken for granted. Most tests
therefore simply use matchall, one uses flower to match on IP address.
As a result, the selftests are noisy, because besides the primary ICMP
traffic, any amount of other service traffic is mirrored as well.
mirror_test() accommodated this noisiness by giving the counters an
allowance of several packets. But in the previous patch, where possible,
counter taps were changed to match only on an exact ICMP message. At least
in those cases, we can demand an exact number of packets to match.
Where the tap is installed on a connective netdevice, the exact matching is
not practical (though with u32, anything is possible). In those places,
there should still be some leeway -- and probably bigger than before,
because experience shows that these tests are very noisy.
To that end, change mirror_test() so that it can be either called with an
exact number to expect, or with an expression. Where leeway is needed,
adjust callers to pass a ">= 10" instead of mere 10.

However, often the counter tap is installed at the remote end of the gretap

arbitrarily accurate.
Thus in this patch, add parameters forward_type and backward_type to
several mirroring test helpers, as some other helpers already have. Then
change do_test_span_dir_ips() to instead of installing one generic tap and
using it for test in both directions, install the tap for each direction
separately, matching on the ICMP type given by these parameters.

The test works by sending packets through a tunnel, whence they are
forwarded to a LAG. One of the LAG children is removed from the LAG prior
to the exercise, and the test then counts how many packets pass through the
other one. The issue with this is that it counts all packets, not just the
encapsulated ones.
So instead add a second gretap endpoint to receive the sent packets, and
check reception counters there.

In some functions, argument-forwarding through "$@" without listing the
individual arguments explicitly is fundamental to the operation of a
function. E.g. xfail_on_veth() should be able to run various tests in the
fail-to-xfail regime, and usage of "$@" is appropriate as an abstraction
mechanism. For functions such as simple_if_init(), $@ is a handy way to
pass an array.
In other functions, it's merely a mechanism to save some typing, which
however ends up obscuring the real arguments and makes life hard for those
that end up reading the code.
This patch adds some of the implicit function arguments and correspondingly
expands $@'s. In several cases this will come in handy as following patches
adjust the parameter lists.

The current pmtu test infrastucture requires an installed copy of the
ovs-vswitchd userspace. This means that any automated or constrained
environments may not have the requisite tools to run the tests. However,
the pmtu tests don't require any special classifier processing. Indeed
they are only using the vswitchd in the most basic mode - as a NORMAL
switch.
However, the ovs-dpctl kernel utility can now program all the needed basic
flows to allow traffic to traverse the tunnels and provide support for at
least testing some basic pmtu scenarios. More complicated flow pipelines
can be added to the internal ovs test infrastructure, but that is work for
the future. For now, enable the most common cases - wide mega flows with
no other prerequisites.
Enhance the pmtu testing to try testing using the internal utility, first.
As a fallback, if the internal utility isn't running, then try with the
ovs-vswitchd userspace tools.
Additionally, make sure that when the pyroute2 package is not available
the ovs-dpctl utility will error out to properly signal an error has
occurred and skip using the internal utility.

set() actions in a single flow. When printing these actions, the existing
code will be unable to print all of the sets - it will only print the
first.
Refactor this code to be easier to read and support multiple actions of the
same type in an action list.

The OVS module can operate in conjunction with various types of
tunnel ports. These are created as either explicit tunnel vport
types, OR by creating a tunnel interface which acts as an anchor
for the lightweight tunnel support.
This patch adds the ability to add tunnel ports to an OVS
datapath for testing various scenarios with tunnel ports. With
this addition, the vswitch "plumbing" will at least be able to
push packets around using the tunnel vports. Future patches
will add support for setting required tunnel metadata for lwts
in the datapath. The end goal will be to push packets via these
tunnels, and will be used in an upcoming commit for testing the
path MTU.
