Po-Hsu Lin 51b6912a6b selftests: net: devlink_port_split.py: skip test if no suitable device available
[ Upstream commit 24994513ad ]

The `devlink -j port show` command output may not contain the "flavour"
key, an example from Ubuntu 22.10 s390x LPAR(5.19.0-37-generic), with
mlx4 driver and iproute2-5.15.0:
  {"port":{"pci/0001:00:00.0/1":{"type":"eth","netdev":"ens301"},
           "pci/0001:00:00.0/2":{"type":"eth","netdev":"ens301d1"},
           "pci/0002:00:00.0/1":{"type":"eth","netdev":"ens317"},
           "pci/0002:00:00.0/2":{"type":"eth","netdev":"ens317d1"}}}

This will cause a KeyError exception.

Create a validate_devlink_output() to check for this "flavour" from
devlink command output to avoid this KeyError exception. Also let
it handle the check for `devlink -j dev show` output in main().

Apart from this, if the test was not started because the max lanes of
the designated device is 0. The script will still return 0 and thus
causing a false-negative test result.

Use a found_max_lanes flag to determine if these tests were skipped
due to this reason and return KSFT_SKIP to make it more clear.

Alexander Lobakin 17d0f2e8da bpf, test_run: fix &xdp_frame misplacement for LIVE_FRAMES
[ Upstream commit 6c20822fad ]

&xdp_buff and &xdp_frame are bound in a way that

xdp_buff->data_hard_start == xdp_frame

It's always the case and e.g. xdp_convert_buff_to_frame() relies on
this.
IOW, the following:

	for (u32 i = 0; i < 0xdead; i++) {
		xdpf = xdp_convert_buff_to_frame(&xdp);
		xdp_convert_frame_to_buff(xdpf, &xdp);
	}

shouldn't ever modify @xdpf's contents or the pointer itself.
However, "live packet" code wrongly treats &xdp_frame as part of its
context placed *before* the data_hard_start. With such flow,
data_hard_start is sizeof(*xdpf) off to the right and no longer points
to the XDP frame.

Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several
places and praying that there are no more miscalcs left somewhere in the
code, unionize ::frm with ::data in a flex array, so that both starts
pointing to the actual data_hard_start and the XDP frame actually starts
being a part of it, i.e. a part of the headroom, not the context.
A nice side effect is that the maximum frame size for this mode gets
increased by 40 bytes, as xdp_buff::frame_sz includes everything from
data_hard_start (-> includes xdpf already) to the end of XDP/skb shared
info.
Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it
hardcoded for 64 bit && 4k pages, it can be made more flexible later on.

Minor: align `&head->data` with how `head->frm` is assigned for
consistency.
Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for
clarity.

(was found while testing XDP traffic generator on ice, which calls
 xdp_convert_frame_to_buff() for each XDP frame)

Hangbin Liu 5d241eb8a1 selftests: nft_nat: ensuring the listening side is up before starting the client
[ Upstream commit 2067e7a00a ]

The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.

Before the fix:
  # ./nft_nat.sh
  PASS: netns routing/connectivity: ns0-rthlYrBU can reach ns1-rthlYrBU and ns2-rthlYrBU
  PASS: ping to ns1-rthlYrBU was ip NATted to ns2-rthlYrBU

Steven Rostedt e10a97f684 ktest.pl: Add RUN_TIMEOUT option with default unlimited
commit 4e7d2a8f0b upstream.

There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.

Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".

But this fixes the hang that happens when the pipe is full and the ssh
session never exits.

Steven Rostedt 81dca9177d ktest.pl: Fix missing "end_monitor" when machine check fails
commit e8bf9b98d4 upstream.

In the "reboot" command, it does a check of the machine to see if it is
still alive with a simple "ssh echo" command. If it fails, it will assume
that a normal "ssh reboot" is not possible and force a power cycle.

In this case, the "start_monitor" is executed, but the "end_monitor" is
not, and this causes the screen will not be given back to the console. That
is, after the test, a "reset" command needs to be performed, as "echo" is
turned off.

Guillaume Tucker 96acb09a34 selftests: find echo binary to use -ne options
[ Upstream commit 4ebe33398c ]

Find the actual echo binary using $(which echo) and use it for
formatted output with -ne.  On some systems, the default echo command
doesn't handle the -e option and the output looks like this (arm64
build):

-ne Emit Tests for alsa

-ne Emit Tests for amd-pstate

-ne Emit Tests for arm64

This is for example the case with the KernelCI Docker images
e.g. kernelci/gcc-10:x86-kselftest-kernelci.  With the actual echo
binary (e.g. in /bin/echo), the output is formatted as expected (x86
build this time):

Emit Tests for alsa
Emit Tests for amd-pstate
Skipping non-existent dir: arm64

Only the install target is using "echo -ne" so keep the $ECHO variable
local to it.

Jiri Pirko 92e832252e sefltests: netdevsim: wait for devlink instance after netns removal
[ Upstream commit f922c7b1c1 ]

When devlink instance is put into network namespace and that network
namespace gets deleted, devlink instance is moved back into init_ns.
This is done as a part of cleanup_net() routine. Since cleanup_net()
is called asynchronously from workqueue, there is no guarantee that
the devlink instance move is done after "ip netns del" returns.

So fix this race by making sure that the devlink instance is present
before any other operation.

[ Upstream commit b60417a9f2 ]

Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.

A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.

Jakub Sitnicki 5982e3f488 selftests/net: Interpret UDP_GRO cmsg data as an int value
[ Upstream commit 436864095a ]

Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:

  recvmsg(8, {msg_name=...,
              msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
              msg_iovlen=1,
              msg_control=[{cmsg_len=20,         <-- sizeof(cmsghdr) + 4
                            cmsg_level=SOL_UDP,
                            cmsg_type=0x68}],    <-- UDP_GRO
                            msg_controllen=24,
                            msg_flags=0}, 0) = 11200

Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

Building BPF selftests out of srctree fails with:

  make: *** No rule to make target '/linux-build//ima_setup.sh', needed by 'ima_setup.sh'.  Stop.

The culprit is the rule that defines convenient shorthands like
"make test_progs", which builds $(OUTPUT)/test_progs. These shorthands
make sense only for binaries that are built though; scripts that live
in the source tree do not end up in $(OUTPUT).

Therefore drop $(TEST_PROGS) and $(TEST_PROGS_EXTENDED) from the rule.

The issue exists for a while, but it became a problem only after commit
d68ae4982c ("selftests/bpf: Install all required files to run selftests"),
