b6ab64b074 selftests: mptcp: more stable simult_flows tests
Currently the simult_flows.sh self-tests are not very stable,
especially when running on slow VMs.

The tests measure runtime for transfers on multiple subflows
and check that the time is near the theoretical maximum.

The current test infra introduces a bit of jitter in test
runtime, due to multiple explicit delays. Additionally the
runtime is measured by the shell script wrapper. On a slow
VM, the script overhead is measurable and subject to relevant
jitter.

One solution to make the test more stable would be adding more
slack to the expected time; that could possibly hide real
regressions. Instead move the measurement inside the command
doing the transfer, and drop most unneeded sleeps.

value which is chosen by user-space instead of calculating it based on
multicast_query_interval and multicast_query_response_interval I forgot
to update the selftests relying on that behaviour. Now we have to
manually set the expected GMI value to perform the tests correctly and get
proper results (similar to IGMPv2 behaviour).

b8bfafe434 selftests: mlxsw: Add helpers for skipping selftests
A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.

Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:

	mlxsw_only_on_spectrum 2+ || return

Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.

as a safety restriction to avoid uncontrolled resource consumption
on busy servers.

Still the system admin and/or the application have to opt-in to
MPTCP explicitly. After that, they need to change (increase) the
default maximum number of additional subflows.

Let set that to reasonable default, and make end-users life easier.

Applications using tcp_l3mdev_accept=1 and a single global socket (not
bound to any interface) also should have a way to specify keys that are
only for the default VRF, this is done by --force-bind-key-ifindex
without otherwise binding to a device.

b69c99463d selftests: net: fib_nexthops: Wait before checking reported idle time
The purpose of this test is to verify that after a short activity passes,
the reported time is reasonable: not zero (which could be reported by
mistake), and not something outrageous (which would be indicative of an
issue in used units).

However, the idle time is reported in units of clock_t, or hundredths of
second. If the initial sequence of commands is very quick, it is possible
that the idle time is reported as just flat-out zero. When this test was
recently enabled in our nightly regression, we started seeing spurious
failures for exactly this reason.

Therefore buffer the delay leading up to the test with a sleep, to make
sure there is no legitimate way of reporting 0.

Makefile uses TEST_PROGS instead of TEST_GEN_PROGS to define
executables. TEST_PROGS is for shell scripts that need to be
installed and run by the common lib.mk framework. The common
framework doesn't touch TEST_PROGS when it does build and clean.

As a result "make kselftest-clean" and "make clean" fail to remove
executables. Run and install work because the common framework runs
and installs TEST_PROGS. Build works because the Makefile defines
"all" rule which is unnecessary if TEST_GEN_PROGS is used.

Use TEST_GEN_PROGS so the common framework can handle build/run/
install/clean properly.

ce9979129a selftests: mptcp: add mptcp getsockopt test cases
Add a test program that retrieves the three info types:
1. mptcp meta information
2. tcp info for subflow
3. subflow endpoint addresses

For all three rudimentary checks are added.

1. Meta information checks that the logical mptcp
   sequence numbers advance as expected, based on the bytes read
   (init seq + bytes_received/sent) and the connection state
   (after close, we should exect 1 extra byte due to FIN).

2. TCP info checks the number of bytes sent/received vs.
   sums of read/write syscall return values.

3. Subflow endpoint addresses are checked vs. getsockname/getpeername
   result.

Tests for forward compatibility (0-initialisation of output-only
fields in mptcp_subflow_data structure) are added as well.

9af771d2ec selftests/net: allow GRO coalesce test on veth
This change extends the existing GRO coalesce test to
allow running on top of a veth pair, so that no H/W dep
is required to run them.

By default gro.sh will use the veth backend, and will try
to use exiting H/W in loopback mode if a specific device
name is provided with the '-i' command line option.

No functional change is intended for the loopback-based
tests, just move all the relevant initialization/cleanup
code into the related script.

Introduces a new initialization helper script for the
veth backend, and plugs the correct helper script according
to the provided command line.

Additionally, enable veth-based tests by default.

7844ec21a9 selftests/net: Use kselftest skip code for skipped tests
There are several test cases in the net directory are still using
exit 0 or exit 1 when they need to be skipped. Use kselftest
framework skip code instead so it can help us to distinguish the
return status.

Criterion to filter out what should be fixed in net directory:
  grep -r "exit [01]" -B1 | grep -i skip

This change might cause some false-positives if people are running
these test scripts directly and only checking their return codes,
which will change from 0 to 4. However I think the impact should be
small as most of our scripts here are already using this skip code.
And there will be no such issue if running them with the kselftest
framework.

As previously discussed with David Ahern, here is a refactored and improved
version of the IOAM self-test. It is now more complete and more robust. Now,
all tests are divided into three categories: OUTPUT (evaluates the IOAM
processing by the sender), INPUT (evaluates the IOAM processing by the receiver)
and GLOBAL (evaluates wider use cases that do not fall into the other two
categories). Both OUTPUT and INPUT tests only use a two-node topology (alpha and
beta), while GLOBAL tests use the entire three-node topology (alpha, beta,
gamma). Each test is documented inside its own handler in the (bash) script.

7d1575014a selftests/net: GRO coalesce test
Implement a GRO testsuite that expects Linux kernel GRO behavior.
All tests pass with the kernel software GRO stack. Run against a device
with hardware GRO to verify that it matches the software stack.

gro.c generates packets and sends them out through a packet socket. The
receiver in gro.c (run separately) receives the packets on a packet
socket, filters them by destination ports using BPF and checks the
packet geometry to see whether GRO was applied.

gro.sh provides a wrapper to run the gro.c in NIC loopback mode.
It is not included in continuous testing because it modifies network
configuration around a physical NIC: gro.sh sets the NIC in loopback
mode, creates macvlan devices on the physical device in separate
namespaces, and sends traffic generated by gro.c between the two
namespaces to observe coalescing behavior.

GRO coalescing is time sensitive.
Some tests may prove flaky on some hardware.

Note that this test suite tests for software GRO unless hardware GRO is
enabled (ethtool -K $DEV rx-gro-hw on).

To test, run ./gro.sh.
The wrapper will output success or failed test names, and generate
log.txt and stderr.

Sample log.txt result:
...
pure data packet of same size: Test succeeded

large data packets followed by a smaller one: Test succeeded

small data packets followed by a larger one: Test succeeded
...

Sample stderr result:
...
carrier ready
running test ipv4 data
Expected {200 }, Total 1 packets
Received {200 }, Total 1 packets.

This test evaluates the IOAM insertion for IPv6 by checking the IOAM data
integrity on the receiver.

The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between)
and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only,
which means not on the reverse path. When Gamma is the destination, Alpha
adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the
trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM
data integrity is checked on Gamma, by comparing with the pre-defined IOAM
configuration (see below).

After patch "mptcp: fix syncookie process if mptcp can not_accept new

will be replied.

So in case "multiple subflows limited by server", the expected SYN/ACK
number should be 1.

0a36a75c68 selftests: icmp_redirect: support expected failures
According to a comment in commit 99513cfa16 ("selftest: Fixes for
icmp_redirect test") the test "IPv6: mtu exception plus redirect" is
expected to fail, because of a bug in the IPv6 logic that hasn't been
fixed yet apparently.

We should probably consider this failure as an "expected failure",
therefore change the script to return XFAIL for that particular test and
also report the total amount of expected failures at the end of the run.

Without this modification, we were often displaying this error messages:

  FAIL: Could not even run loopback test

But $ret could have been set to a non 0 value in many different cases:

- net.mptcp.enabled=0 is not working as expected
- setsockopt(..., TCP_ULP, "mptcp", ...) is allowed
- ping between each netns are failing
- tests between ns1 as a receiver and ns>1 are failing
- other tests not involving ns1 as a receiver are failing

So not only for the loopback test.

Now a clearer message, including the time it took to run all tests, is
displayed.

af66d3e1c3 selftests: mptcp: enable checksum in mptcp_join.sh
This patch added a new argument "-C" for the mptcp_join.sh script to set
the sysctl checksum_enabled to 1 in ns1 and ns2 to enable the data
checksum.

In chk_join_nr, check the counter of the mib for the data checksum.

Also added a new argument "-S" for the mptcp_join.sh script to start the
test cases that verify the checksum handshake:

  * Sender and listener both have checksums off
  * Sender and listener both have checksums on
  * Sender checksums off, listener checksums on
  * Sender checksums on, listener checksums off

The output looks like this:

 01 checksum test 0 0                  sum[ ok ] - csum  [ ok ]
 02 checksum test 1 1                  sum[ ok ] - csum  [ ok ]
 03 checksum test 0 1                  sum[ ok ] - csum  [ ok ]
 04 checksum test 1 0                  sum[ ok ] - csum  [ ok ]
 05 no JOIN                            syn[ ok ] - synack[ ok ] - ack[ ok ]
                                       sum[ ok ] - csum  [ ok ]
 06 single subflow, limited by client  syn[ ok ] - synack[ ok ] - ack[ ok ]
                                       sum[ ok ] - csum  [ ok ]

0fd158b89b selftests: net: veth: make test compatible with dash
veth.sh is a shell script that uses /bin/sh; some distro (Ubuntu for
example) use dash as /bin/sh and in this case the test reports the
following error:

 # ./veth.sh: 21: local: -r: bad variable name
 # ./veth.sh: 21: local: -r: bad variable name

This happens because dash doesn't support the option "-r" with local.

Moreover, in case of missing bpf object, the script is exiting -1, that
is an illegal number for dash:

 exit: Illegal number: -1

Change the script to be compatible both with bash and dash and prevent
the errors above.

b87b04f501 ipv4: Fix device used for dst_alloc with local routes
Oliver reported a use case where deleting a VRF device can hang
waiting for the refcnt to drop to 0. The root cause is that the dst
is allocated against the VRF device but cached on the loopback
device.

The use case (added to the selftests) has an implicit VRF crossing
due to the ordering of the FIB rules (lookup local is before the
l3mdev rule, but the problem occurs even if the FIB rules are
re-ordered with local after l3mdev because the VRF table does not
have a default route to terminate the lookup). The end result is
is that the FIB lookup returns the loopback device as the nexthop,
but the ingress device is in a VRF. The mismatch causes the dst
alloc against the VRF device but then cached on the loopback.

The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu):
pick the dst alloc device based the fib lookup result but with checks
that the result has a nexthop device (e.g., not an unreachable or
prohibit entry).

0521a262f0 selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEV
In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.

Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.

In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.

77a88274dc kbuild: replace LANG=C with LC_ALL=C
LANG gives a weak default to each LC_* in case it is not explicitly
defined. LC_ALL, if set, overrides all other LC_* variables.

  LANG  <  LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ...  <  LC_ALL

This is why documentation such as [1] suggests to set LC_ALL in build
scripts to get the deterministic result.

LANG=C is not strong enough to override LC_* that may be set by end
users.

b881d089c7 selftests/net: bump timeout to 5 minutes
We found that with the latest mainline kernel (5.12.0-051200rc8) on
some KVM instances / bare-metal systems, the following tests will take
longer than the kselftest framework default timeout (45 seconds) to
run and thus got terminated with TIMEOUT error:
* xfrm_policy.sh - took about 2m20s
* pmtu.sh - took about 3m5s
* udpgso_bench.sh - took about 60s

Bump the timeout setting to 5 minutes to allow them have a chance to
finish.

1233898ab7 selftests: mlxsw: Fix mausezahn invocation in ERSPAN scale test
The mirror_gre_scale test creates as many ERSPAN sessions as the underlying
chip supports, and tests that they all work. In order to determine that it
issues a stream of ICMP packets and checks if they are mirrored as
expected.

However, the mausezahn invocation missed the -6 flag to identify the use of
IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to
ICMP6. It also didn't pass an explicit source IP address, which apparently
worked at some point in the past, but does not anymore.

To fix these issues, extend the function mirror_test() in mirror_lib by
detecting the IPv6 protocol addresses, and using a different ICMP scheme.
Fix __mirror_gre_test() in the selftest itself to pass a source IP address.

c8d0260cdd selftests: net: mirror_gre_vlan_bridge_1q: Make an FDB entry static
The FDB roaming test installs a destination MAC address on the wrong
interface of an FDB database and tests whether the mirroring fails, because
packets are sent to the wrong port. The test by mistake installs the FDB
entry as local. This worked previously, because drivers were notified of
local FDB entries in the same way as of static entries. However that has
been fixed in the commit 6ab4c3117a ("net: bridge: don't notify switchdev
for local FDB addresses"), and local entries are not notified anymore. As a
result, the HW is not reconfigured for the FDB roam, and mirroring keeps
working, failing the test.

To fix the issue, mark the FDB entry as static.

5888a61cb4 selftests: mptcp: launch mptcp_connect with timeout
'mptcp_connect' already has a timeout for poll() but in some cases, it
is not enough.

With "timeout" tool, we will force the command to fail if it doesn't
finish on time. Thanks to that, the script will continue and display
details about the current state before marking the test as failed.
Displaying this state is very important to be able to understand the
issue. Best to have our CI reporting the issue than just "the test
hanged".

Note that in mptcp_connect.sh, we were using a long timeout to validate
the fact we cannot create a socket if a sysctl is set. We don't need
this timeout.

In diag.sh, we want to send signals to mptcp_connect instances that have
been started in the netns. But we cannot send this signal to 'timeout'
otherwise that will stop the timeout and messages telling us SIGUSR1 has
been received will be printed. Instead of trying to find the right PID
and storing them in an array, we can simply use the output of
'ip netns pids' which is all the PIDs we want to send signal to.

6254ad4088 selftests: mptcp: avoid calling pm_nl_ctl with bad IDs
IDs are supposed to be between 0 and 255.

In pm_nl_ctl, for both the 'add' and 'get' instruction, the ID is casted
in a u_int8_t. So if we give 256, we will delete ID 0. Obviously, the
goal is not to delete this ID by giving 256.

We could modify pm_nl_ctl and stop if the ID is negative or higher than
255 but probably better not to increase the number of lines for such
things in this tool which is only used in selftests. Instead, we use it
within the limits.

This modification also means that we will no longer add a new ID for the
2nd entry. That's why we removed an expected entry from the dump and
introduced with
commit dc8eb10e95 ("selftests: mptcp: add testcases for setting the address ID").

So now we delete ID 9 like before and we add entries for IDs 10 to 255
that are deleted just after.

Note that this could be seen as a fix but it was not really an issue so
far: we were simply playing with ID 0/1 once again. With the following
commit ("selftests: mptcp: add addr argument for del_addr"), it will be
different because ID 0 is going to required an address. We don't want
errors when trying to delete ID 0 without the address argument.

a673321aa7 selftests: mptcp: Restore packet capture option in join tests
The join self tests previously used the '-c' command line option to
enable creation of pcap files for the tests that run, but the change to
allow running a subset of the join tests made overlapping use of that
option.

Restore the capture functionality with '-c' and move the syncookie test
option to '-k'.

7028ba8ac9 selftests: mptcp: add invert argument for chk_rm_nr
Some of the removing testcases used two zeros as arguments for chk_rm_nr
like this: chk_rm_nr 0 0. This doesn't mean that no RM_ADDR has been sent.
It only means that RM_ADDR had been sent in the opposite direction that
chk_rm_nr is checking.

This patch added a new argument invert for chk_rm_nr to allow it can
check the RM_ADDR from the opposite direction.

edcbf5137f selftests: forwarding: Fix race condition in mirror installation
When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.

If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.

Fix this by setting the neighbor's state to permanent, so that it is
always valid.

and second labels. For each field, the minimal and maximal values are
tested (the former at depth 1 and the later at depth 2).
There are also tests for matching the presence of a label stack entry
at a given depth.

In order to reduce the amount of code, all "lse" subcommands are tested
in match_mpls_lse_test(). Action "continue" is used, so that test
packets are evaluated by all filters. Then, we can verify if each
filter matched the expected number of packets.

Some versions of tc-flower produced invalid json output when dumping
MPLS filters with depth > 1. Skip the test if tc isn't recent enough.

203ee5cd72 selftests: tc: Add basic mpls_* matching support for tc-flower
Add tests in tc_flower.sh for mpls_label, mpls_tc, mpls_bos and
mpls_ttl. For each keyword, test the minimal and maximal values.

Selectively skip these new mpls tests for tc versions that don't
support them.

d212683805 flow_dissector: fix TTL and TOS dissection on IPv4 fragments
the following command:

 # tc filter add dev $h2 ingress protocol ip pref 1 handle 101 flower \
   $tcflags dst_ip 192.0.2.2 ip_ttl 63 action drop

doesn't drop all IPv4 packets that match the configured TTL / destination
address. In particular, if "fragment offset" or "more fragments" have non
zero value in the IPv4 header, setting of FLOW_DISSECTOR_KEY_IP is simply
ignored. Fix this dissecting IPv4 TTL and TOS before fragment info; while
at it, add a selftest for tc flower's match on 'ip_ttl' that verifies the
correct behavior.
