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.

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.

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.

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:
...

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).

Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace
option inside a Hop-by-hop, where 164 bytes are pre-allocated for the
trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace
type (= all available options at this time). As a result, and based on
IOAM configurations here, only both Alpha and Beta should be capable of
inserting their IOAM data while Gamma won't have enough space and will
set the overflow bit.

After redirecting, it's already a new path. So the old PMTU info should
be cleared. The IPv6 test "mtu exception plus redirect" should only
has redirect info without old PMTU.
The IPv4 test can not be changed because of legacy.

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.

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 ]

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.

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).
Fixes: f5a0aab84b ("net: ipv4: dst for local input routes should use l3mdev if relevant")
