Add a simple bpf_modify_return_test_tp() kfunc, available to all program
types, that is useful for various testing and benchmarking scenarios, as
it allows to trigger most tracing BPF program types from BPF side,
allowing to do complex testing and benchmarking scenarios.
It is also attachable to for fmod_ret programs, making it a good and
simple way to trigger fmod_ret program under test/benchmark.

Instead of front-loading all possible benchmarking BPF programs for
trigger benchmarks, explicitly specify which BPF programs are used by
specific benchmark and load only it.
This allows to be more flexible in supporting older kernels, where some
program types might not be possible to load (e.g., those that rely on
newly added kfunc).

Remove "legacy" benchmarks triggered by syscalls in favor of newly added
in-kernel/batched benchmarks. Drop -batched suffix now as well.
Next patch will restore "feature parity" by adding back
tp/raw_tp/fmodret benchmarks based on in-kernel kfunc approach.

Existing kprobe/fentry triggering benchmarks have 1-to-1 mapping between
one syscall execution and BPF program run. While we use a fast
get_pgid() syscall, syscall overhead can still be non-trivial.
This patch adds kprobe/fentry set of benchmarks significantly amortizing
the cost of syscall vs actual BPF triggering overhead. We do this by
employing BPF_PROG_TEST_RUN command to trigger "driver" raw_tp program
which does a tight parameterized loop calling cheap BPF helper
(bpf_get_numa_node_id()), to which kprobe/fentry programs are
attached for benchmarking.
This way 1 bpf() syscall causes N executions of BPF program being
benchmarked. N defaults to 100, but can be adjusted with
--trig-batch-iters CLI argument.
For comparison we also implement a new baseline program that instead of
triggering another BPF program just does N atomic per-CPU counter
increments, establishing the limit for all other types of program within
this batched benchmarking setup.
Taking the final set of benchmarks added in this patch set (including
tp/raw_tp/fmodret, added in later patch), and keeping for now "legacy"
syscall-driven benchmarks, we can capture all triggering benchmarks in
one place for comparison, before we remove the legacy ones (and rename
xxx-batched into just xxx).

kretprobe-multi-legacy: 3.193 ± 0.001M/s
Note how xxx-batch variants are measured with significantly higher
throughput, even though it's exactly the same in-kernel overhead. As
such, results can be compared only between benchmarks of the same kind
(syscall vs batched):
fentry-legacy : 8.329 ± 0.004M/s
fentry-batch : 31.002 ± 0.015M/s
kprobe-multi-legacy : 5.864 ± 0.022M/s
kprobe-multi-batch : 15.400 ± 0.007M/s
Note also that syscall-count is setting a theoretical limit for
syscall-triggered benchmarks, while kernel-count is setting similar
limits for batch variants. usermode-count is a happy and unachievable
case of user space counting without doing any syscalls, and is mostly
the measure of CPU speed for such a trivial benchmark.
As was mentioned, tp/raw_tp/fmodret require kernel-side kfunc to produce
similar benchmark, which we address in a separate patch.
Note that run_bench_trigger.sh allows to override a list of benchmarks
to run, which is very useful for performance work.

ravb: Support describing the MDIO bus
This series adds support to the binding and driver of the Renesas
Ethernet AVB to described the MDIO bus. Currently the driver uses
the OF node of the device itself when registering the MDIO bus.
This forces any MDIO bus properties the MDIO core should react on
to be set on the device OF node. This is confusing and none of
the MDIO bus properties are described in the Ethernet AVB bindings.
Patch 1/2 extends the bindings with an optional mdio child-node
to the device that can be used to contain the MDIO bus settings.
While patch 2/2 changes the driver to use this node (if present)
when registering the MDIO bus.
If the new optional mdio child-node is not present the driver
fallback to the old behavior and uses the device OF node like before.
This change is fully backward compatible with existing usage
of the bindings.

The driver used the DT node of the device itself when registering the
MDIO bus. While this works, it creates a problem: it forces any MDIO bus
properties to also be set on the devices DT node. This mixes the
properties of two distinctly different things and is confusing.
This change adds support for an optional mdio node to be defined as a
child to the device DT node. The child node can then be used to describe
MDIO bus properties that the MDIO core can act on when registering the
bus.
If no mdio child node is found the driver fallback to the old behavior
and register the MDIO bus using the device DT node. This change is
backward compatible with old bindings in use.

The Renesas Ethernet AVB bindings do not allow the MDIO bus to be

selftests: Fixes for kernel CI
As discussed on the bi-weekly call on Jan 30, and in mailing around
kernel CI effort, some changes are desirable in the suite of forwarding
selftests the better to work with the CI tooling. Namely:
- The forwarding selftests use a configuration file where names of
interfaces are defined and various variables can be overridden. There
is also forwarding.config.sample that users can use as a template to
refer to when creating the config file. What happens a fair bit is
that users either do not know about this at all, or simply forget, and
are confused by cryptic failures about interfaces that cannot be
created.
In patches #1 - #3 have lib.sh just be the single source of truth with
regards to which variables exist. That includes the topology variables
which were previously only in the sample file, and any "tweak
variables", such as what tools to use, sleep times, etc.
forwarding.config.sample then becomes just a placeholder with a couple
examples. Unless specific HW should be exercised, or specific tools
used, the defaults are usually just fine.
- Several net/forwarding/ selftests (and one net/ one) cannot be run on
veth pairs, they need an actual HW interface to run on. They are
generic in the sense that any capable HW should pass them, which is
why they have been put to net/forwarding/ as opposed to drivers/net/,
but they do not generalize to veth. The fact that these tests are in
net/forwarding/, but still complaining when run, is confusing.
In patches #4 - #6 move these tests to a new directory
drivers/net/hw.
- The following patches extend the codebase to handle well test results
other than pass and fail.
Patch #7 is preparatory. It converts several log_test_skip to XFAIL,
so that tests do not spuriously end up returning non-0 when they
are not supposed to.
In patches #8 - #10, introduce some missing ksft constants, then support
having those constants in RET, and then finally in EXIT_STATUS.
- The traffic scheduler tests generate a large amount of network traffic
to test the behavior of the scheduler. This demands a relatively
high-performance computer. On slow machines, such as with a debugging
kernel, the test would spuriously fail.
It can still be useful to "go through the motions" though, to possibly
catch bugs in setup of the scheduler graph and passing packets around.
Thus we still want to run the tests, just with lowered demands.
To that end, in patches #11 - #12, introduce an environment variable
KSFT_MACHINE_SLOW, with obvious meaning. Tests can then make checks
more lenient, such as mark failures as XFAIL. A helper, xfail_on_slow,
is provided to mark performance-sensitive parts of the selftest.
- In patch #13, use a similar mechanism to mark a NH group stats
selftest to XFAIL HW stats tests when run on VETH pairs.
- All these changes complicate the hitherto straightforward logging and
checking logic, so in patch #14, add a selftest that checks this
functionality in lib.sh.
v1 (vs. an RFC circulated through linux-kselftest):
- Patch #9:
- Clarify intended usage by s/set_ret/ret_set_ksft_status/,
s/nret/ksft_status/

Rerunning various scenarios to make sure lib.sh changes do not impact the
observable behavior is no fun. Add a selftest at least for the bare basics
-- the mechanics of setting RET, retmsg, and EXIT_STATUS.
Since the selftest itself uses lib.sh, it would be possible to break lib.sh
in such a way that invalidates result of the selftest. Since the metatest
only uses the bare basics (just pass/fail), hopefully such fundamental
breakages would be noticed.

When the NH group stats tests are currently run on a veth topology, the
HW-stats leg of each test is SKIP'ped. But kernel networking CI interprets
skips as a sign that tooling is missing, and prompts maintainer
investigation. Lack of capability to pass a test should be expressed as
XFAIL.
Selftests that require HW should normally be put in drivers/net/hw, but
doing so for the NH counter selftests would just lead to a lot of
duplicity.
So instead, introduce a helper, xfail_on_veth(), which can be used to mark
selftests that should XFAIL instead of FAILing when run on a veth topology.
On non-veth topology, they don't do anything.
Use the helper in the HW-stats part of router_mpath_nh_lib selftest.

Several tests in the suite use large amounts of traffic to e.g. cause
congestion and evaluate RED or shaper performance. These tests will not run
well on a slow machine, be it one with heavy debug kernel, or a VM, or e.g.
a single-board computer. Allow users to specify an environment variable,
KSFT_MACHINE_SLOW=yes, to indicate that the tests are being run on one such
machine.
Performance sensitive tests can then use a new helper, xfail_on_slow(), to
mark parts of the test that are sensitive to low-performance machines.
The helper can be used to just mark the whole suite, like so:
xfail_on_slow tests_run
... or, on the other side of the granularity spectrum, to override
individual checks:
xfail_on_slow check_err $? "Expected much, got little."

In a previous patch, the interpretation of RET value was changed to mean
the kselftest framework constant with the test outcome: $ksft_pass,
$ksft_xfail, etc.
Update log_test() to recognize the various possible RET values.
Then have EXIT_STATUS track the RET value of the current test. This differs
subtly from the way RET tracks the value: while for RET we want to
recognize XFAIL as a separate status, for purposes of exit code, we want to
to conflate XFAIL and PASS, because they both communicate non-failure. Thus
add a new helper, ksft_exit_status_merge().
With this log_test_skip() and log_test_xfail() can be reexpressed as thin
wrappers around log_test.

The variable RET keeps track of whether the test under execution has so far
failed or not. Currently it works in binary fashion: zero means everything
is fine, non-zero means something failed. log_test() then uses the value to
given a human-readable message.
In order to allow log_test() to report skips and xfails, the semantics of
RET need to be more fine-grained. Therefore have RET value be one of
kselftest framework constants: $ksft_fail, $ksft_xfail, etc.
The current logic in check_err() is such that first non-zero value of RET
trumps all those that follow. But that is not right when RET has more
fine-grained value semantics. Different outcomes have different weights.
The results of PASS and XFAIL are mostly the same: they both communicate a
test that did not go wrong. SKIP communicates lack of tooling, which the
user should go and try to fix, and as such should not be overridden by the
passes. So far, the higher-numbered statuses can be considered weightier.
But FAIL should be the weightiest.
Add a helper, ksft_status_merge(), which merges two statuses in a way that
respects the above conditions. Express it in a generic manner, because exit
status merge is subtly different, and we want to reuse the same logic.
Use the new helper when setting RET in check_err().
Re-express check_fail() in terms of check_err() to avoid duplication.

Additionally, move a duplicated skip exit code definition from

been sourced in all cases where devlink_lib is, the inclusion is not

The SKIP return should be used for cases where tooling of the machine under
test is lacking. For cases where HW is lacking, the appropriate outcome is
XFAIL.
This is the case with ethtool_rmon and mlxsw_lib. For these, introduce a
new helper, log_test_xfail().
Do the same for router_mpath_nh_lib. Note that it will be fixed using a
more reusable way in a following patch.
For the two resource_scale selftests, the log should simply not be written,
because there is no problem.

The tests in net/forwarding are generally expected to be HW-independent.
There are however several tests that, while not depending on any HW in
particular, nevertheless depend on being used on HW interfaces. Placing
these selftests to net/forwarding is confusing, because the selftest will
just report it can't be run on veth pairs. At the same time, placing them
to a particular driver's selftests subdirectory would be wrong.
Instead, add a new directory, drivers/net/hw, where these generic but HW
independent selftests should be placed. Move over several such tests
including one helper library.
Since typically these tests will not be expected to run, omit the directory
drivers/net/hw from the TARGETS list in selftests/Makefile. Retain a
Makefile in the new directory itself, so that a user can make -C into that
directory and act on those tests explicitly.

to already have done it. This will simplify moving some of the clients to a
different directory.

forwarding.config.sample, net/lib.sh and net/forwarding/lib.sh contain
definitions and redefinitions of some of the same variables. The overlap
between net/forwarding/lib.sh and forwarding.config.sample is especially
large. This duplication is a potential source of confusion and problems.
It would be overall less error prone if each variable were defined in one
place only. In this patch set, that place is the library itself. Therefore
move all comments from forwarding.config.sample to net/forwarding/lib.sh.
Move over also a definition of TC_FLAG, which was missing from lib.sh
entirely.
Additionally, add to lib.sh a default definition of the topology variables.
The logic behind this is that forgetting to specify forwarding.config was a
frequent source of frustration for the selftest users. But really, most of
the time the default veth based topology is just fine. We considered just
sourcing forwarding.config.sample instead if forwarding.config is not
available, but this is a cleaner solution.
That means the syntax of the forwarding.config.sample override has to
change to an array assignment, so that the whole variable is overwritten,
not just individual keys, which could leave the value of some keys
unchanged. Do the same in lib.sh for any cut'n'pasters out there.
The config file is then given a sort of carte blanche to redefine whatever
variables it sees fit from the libraries. This is described in a comment in
the file. Only a handful of variables are left behind, to illustrate the
customization.
The fact that the variables are now missing from forwarding.config.sample,
and therefore would miss from forwarding.config derived from that file as
well, should not change anything. This is just the sample file. Users that
keep their own forwarding.config would retain it as before.
The only observable change is introduction of TC_FLAG to lib.sh, because
now the filters would not be attempted to install to HW datapath. For veth
pairs this does not change anything. For HW deployments, users presumably
have forwarding.config with this value overridden.

The current syntax of X=${X:=X} first evaluates the ${X:=Y} expression,
which either uses the existing value of $X if there is one, or uses the
value of "Y" as a fallback, and assigns it to X. The expression is then
replaced with the now-current value of $X. Assigning that value to X once
more is meaningless.
So avoid the outer X=... bit, and instead express the same idea though the
do-nothing ":" built-in as : "${X:=Y}". This also cleans up the block
nicely and makes it more readable.

ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released.
This affects skb fragments reassembled via netfilter or similar
modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.
Eric Dumazet made an initial analysis of this bug. Quoting Eric:
Calling ip_defrag() in output path is also implying skb_orphan(),
which is buggy because output path relies on sk not disappearing.
A relevant old patch about the issue was :
8282f27449bf ("inet: frag: Always orphan skbs inside ip_defrag()")
[..]
net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
inet socket, not an arbitrary one.
If we orphan the packet in ipvlan, then downstream things like FQ
packet scheduler will not work properly.
We need to change ip_defrag() to only use skb_orphan() when really
needed, ie whenever frag_list is going to be used.
Eric suggested to stash sk in fragment queue and made an initial patch.
However there is a problem with this:
If skb is refragmented again right after, ip_do_fragment() will copy
head->sk to the new fragments, and sets up destructor to sock_wfree.
IOW, we have no choice but to fix up sk_wmem accouting to reflect the
fully reassembled skb, else wmem will underflow.
This change moves the orphan down into the core, to last possible moment.
As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
offset into the FRAG_CB, else skb->sk gets clobbered.
This allows to delay the orphaning long enough to learn if the skb has
to be queued or if the skb is completing the reasm queue.
In the former case, things work as before, skb is orphaned. This is
safe because skb gets queued/stolen and won't continue past reasm engine.
In the latter case, we will steal the skb->sk reference, reattach it to
the head skb, and fix up wmem accouting when inet_frag inflates truesize.

On reworking and splitting the at803x driver, in splitting function of
at803x PHYs it was added a NULL dereference bug where priv is referenced
before it's actually allocated and then is tried to write to for the
is_1000basex and is_fiber variables in the case of at8031, writing on
the wrong address.
Fix this by correctly setting priv local variable only after
at803x_probe is called and actually allocates priv in the phydev struct.

syzkaller started to report a warning below [0] after consuming the
commit 4654467dc7e1 ("netfilter: arptables: allow xtables-nft only
builds").
The change accidentally removed the dependency on NETFILTER_FAMILY_ARP
from IP_NF_ARPTABLES.
If NF_TABLES_ARP is not enabled on Kconfig, NETFILTER_FAMILY_ARP will
be removed and some code necessary for arptables will not be compiled.
$ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
CONFIG_NETFILTER_FAMILY_ARP=y
# CONFIG_NF_TABLES_ARP is not set
CONFIG_IP_NF_ARPTABLES=y
$ make olddefconfig
$ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
# CONFIG_NF_TABLES_ARP is not set
CONFIG_IP_NF_ARPTABLES=y
So, when nf_register_net_hooks() is called for arptables, it will
trigger the splat below.
Now IP_NF_ARPTABLES is only enabled by IP_NF_ARPFILTER, so let's
restore the dependency on NETFILTER_FAMILY_ARP in IP_NF_ARPFILTER.

netdev basechain updates are stored in the transaction object hook list.
When setting on the table dormant flag, it iterates over the existing
hooks in the basechain. Thus, skipping the hooks that are being
added/deleted in this transaction, which leaves hook registration in
inconsistent state.
Reject table flag updates in combination with netdev basechain updates
in the same batch:
- Update table flags and add/delete basechain: Check from basechain update
path if there are pending flag updates for this table.
- add/delete basechain and update table flags: Iterate over the transaction
list to search for basechain updates from the table update path.
In both cases, the batch is rejected. Based on suggestion from Florian Westphal.
