selftests/net: test sk_filter support for SKF_NET_OFF on frags

Verify that a classic BPF linux socket filter correctly matches
packet contents. Including when accessing contents in an
skb_frag.

1. Open a SOCK_RAW socket with a classic BPF filter on UDP dport 8000.
2. Open a tap device with IFF_NAPI_FRAGS to inject skbs with frags.
3. Send a packet for which the UDP header is in frag[0].
4. Receive this packet to demonstrate that the socket accepted it.

selftests: net: Add busy_poll_test

Add an epoll busy poll test using netdevsim.

This test is comprised of:
- busy_poller (via busy_poller.c)
- busy_poll_test.sh which loads netdevsim, sets up network namespaces,
and runs busy_poller to receive data and socat to send data.

The selftest tests two different scenarios:
- busy poll (the pre-existing version in the kernel)
- busy poll with suspend enabled (what this series adds)

The data transmit is a 1MiB temporary file generated from /dev/urandom
and the test is considered passing if the md5sum of the input file to
socat matches the md5sum of the output file from busy_poller.

netdevsim was chosen instead of veth due to netdevsim's support for
netdev-genl.

For now, this test uses the functionality that netdevsim provides. In the
future, perhaps netdevsim can be extended to emulate device IRQs to more
thoroughly test all pre-existing kernel options (like defer_hard_irqs)
and suspend.

In addition to normal netcat support, ncdevmem has a validation mode,
where it sends a specific pattern and validates this pattern on the
receiver side to ensure data integrity.

selftests: drv-net: add checksum tests

Run tools/testing/selftest/net/csum.c as part of drv-net.
This binary covers multiple scenarios, based on arguments given,
for both IPv4 and IPv6:

- Accept UDP correct checksum
- Detect UDP invalid checksum
- Accept TCP correct checksum
- Detect TCP invalid checksum

- Transmit UDP: basic checksum offload
- Transmit UDP: zero checksum conversion

The test direction is reversed between receive and transmit tests, so
that the NIC under test is always the local machine.

In total this adds up to 12 testcases, with more to follow. For
conciseness, I replaced individual functions with a function factory.

Also detect hardware offload feature availability using Ethtool
netlink and skip tests when either feature is off. This need may be
common for offload feature tests and eventually deserving of a thin
wrapper in lib.py.

Missing are the PF_PACKET based send tests ('-P'). These use
virtio_net_hdr to program hardware checksum offload. Which requires
looking up the local MAC address and (harder) the MAC of the next hop.
I'll have to give it some though how to do that robustly and where
that code would belong.

Tested:

make -C tools/testing/selftests/ \

We run each test for the following cases:

* SOCK_STREAM without embryo socket + 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].

selftest: Add test for SO_INCOMING_CPU.

Some highly optimised applications use SO_INCOMING_CPU to make them
efficient, but they didn't test if it's working correctly by getsockopt()
to avoid slowing down. As a result, no one noticed it had been broken
for years, so it's a good time to add a test to catch future regression.

The test does

1) Create $(nproc) TCP listeners associated with each CPU.

2) Create 32 child sockets for each listener by calling
sched_setaffinity() for each CPU.

3) Check if accept()ed sockets' sk_incoming_cpu matches
listener's one.

If we see -EAGAIN, SO_INCOMING_CPU is broken. However, we might not see
any error even if broken; the kernel could miraculously distribute all SYN
to correct listeners. Not to let that happen, we must increase the number
of clients and CPUs to some extent, so the test requires $(nproc) >= 2 and
creates 64 sockets at least.

Test:
$ nproc
96
$ ./so_incoming_cpu

and then a listen() on the socket is invoked. The listen() should
succeed.

selftests/net: Add test for timing a bind request to a port with a populated bhash entry

This test populates the bhash table for a given port with
MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long
a bind request on the port takes.

When populating the bhash table, we create the sockets and then bind
the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT
are set). When timing how long a bind on the port takes, we bind on a
different address without SO_REUSEPORT set. We do not set SO_REUSEPORT
because we are interested in the case where the bind request does not
go through the tb->fastreuseport path, which is fragile (eg
tb->fastreuseport path does not work if binding with a different uid).

To run the script:
Usage: ./bind_bhash.sh [-6 | -4] [-p port] [-a address]
6: use ipv6
4: use ipv4
port: Port number
address: ip address

Without any arguments, ./bind_bhash.sh defaults to ipv6 using ip address
"2001:0db8:0:f101::1" on port 443.

On my local machine, I see:
ipv4:
before - 0.002317 seconds
with bhash2 - 0.000020 seconds
