Avoid open-coding that simple expression each time by moving
BYTES_TO_BITS() from the probes code to <linux/bitops.h> to export
it to the rest of the kernel.
Simplify the macro while at it. `BITS_PER_LONG / sizeof(long)` always
equals to %BITS_PER_BYTE, regardless of the target architecture.
Do the same for the tools ecosystem as well (incl. its version of
bitops.h). The previous implementation had its implicit type of long,
while the new one is int, so adjust the format literal accordingly in
the perf code.

This patch adds test cases to verify the new GC.
We run each test for the following cases:
* SOCK_DGRAM
* SOCK_STREAM without embryo socket
* SOCK_STREAM without embryo socket + MSG_OOB
* SOCK_STREAM with embryo sockets
* SOCK_STREAM with embryo sockets + MSG_OOB
Before and after running each test case, we ensure that there is
no AF_UNIX socket left in the netns by reading /proc/net/protocols.
We cannot use /proc/net/unix and UNIX_DIAG because the embryo socket
does not show up there.
Each test creates multiple sockets in an array. We pass sockets in
the even index using the peer sockets in the odd index.
So, send_fd(0, 1) actually sends fd[0] to fd[2] via fd[0 + 1].
Test 1 : A <-> A
Test 2 : A <-> B
Test 3 : A -> B -> C <- D

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.

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.

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.

This patch adds a missing check to bloom filter creating, rejecting
values above KMALLOC_MAX_SIZE. This brings the bloom map in line with
many other map types.
The lack of this protection can cause kernel crashes for value sizes
that overflow int's. Such a crash was caught by syzkaller. The next
patch adds more guard-rails at a lower level.

The longest running netdevsim test, nexthop.sh, currently takes
5 min to finish. Around 260s to be exact, and 310s on a debug kernel.
The default timeout in selftest is 45sec, so we need an explicit
config. Give ourselves some headroom and use 10min.
Commit under Fixes isn't really to "blame" but prior to that
netdevsim tests weren't integrated with kselftest infra
so blaming the tests themselves doesn't seem right, either.

pthread_create followed by fork caused deadlock in certain cases wherein
fork required some work to be completed by the created thread. Used

Add missing flags argument to open(2) call with O_CREAT.
Some tests fail to compile if _FORTIFY_SOURCE is defined (to any valid
value) (together with -O), resulting in similar error messages such as:
In file included from /usr/include/fcntl.h:342,
from gup_test.c:1:
In function 'open',
inlined from 'main' at gup_test.c:206:10:

50 | __open_missing_mode ();
| ^~~~~~~~~~~~~~~~~~~~~~
_FORTIFY_SOURCE is enabled by default in some distributions, so the
tests are not built by default and are skipped.
open(2) man-page warns about missing flags argument: "if it is not
supplied, some arbitrary bytes from the stack will be applied as the
file mode."

Locally generated IP multicast packets (such as the ones used in the
test) do not perform routing and simply egress the bound device.
However, as explained in commit 8bcfb4ae4d ("selftests: forwarding:
Fix failing tests with old libnet"), old versions of libnet (used by
mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically,
the library started using the option for IPv6 sockets in version 1.1.6
and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which
uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6
ones are passing.
Fix by specifying the source and destination MAC of the packets which
will cause mausezahn to use a packet socket instead of an IP socket.

Recently, I frequently hit the following test failure:
[root@arch-fb-vm1 bpf]# ./test_progs -n 33/1
test_lookup_update:PASS:skel_open 0 nsec
[...]
test_lookup_update:PASS:sync_rcu 0 nsec
test_lookup_update:FAIL:map1_leak inner_map1 leaked!
#33/1 btf_map_in_map/lookup_update:FAIL
#33 btf_map_in_map:FAIL
In the test, after map is closed and then after two rcu grace periods,
it is assumed that map_id is not available to user space.
But the above assumption cannot be guaranteed. After zero or one
or two rcu grace periods in different siturations, the actual
freeing-map-work is put into a workqueue. Later on, when the work
is dequeued, the map will be actually freed.
See bpf_map_put() in kernel/bpf/syscall.c.
By using workqueue, there is no ganrantee that map will be actually
freed after a couple of rcu grace periods. This patch removed
such map leak detection and then the test can pass consistently.

Some distros seem to enable the -fcf-protection=branch by default,
which breaks our setup on first instruction of uprobe trigger
functions and place there endbr64 instruction.
Marking them with nocf_check attribute to skip that.
Ignoring unknown attribute warning in gcc for bench objects, because
nocf_check can be used only when -fcf-protection=branch is enabled,
otherwise we get a warning and break compilation.

With glibc 2.28, selftests compilation fails for benchs/bench_trigger.c:
benchs/bench_trigger.c: In function ‘inc_counter’:
benchs/bench_trigger.c:25:23: error: implicit declaration of function ‘gettid’; did you mean ‘getgid’? [-Werror=implicit-function-declaration]
25 | tid = gettid();
| ^~~~~~
| getgid
cc1: all warnings being treated as errors
It appears support for the gettid() wrapper is variable across glibc
versions, so may be safer to use syscall(SYS_gettid) instead.
