If we receive a UDP packet (directed towards an active OpenVPN socket)
which is too short to contain an OpenVPN header ('struct
ovpn_wire_header') we wound up making m_copydata() read outside the
mbuf, and panicking the machine.
Explicitly check that the packet is long enough to copy the data we're
interested in. If it's not we will pass the packet to userspace, just
like we'd do for an unknown peer.
Extend a test case to provoke this situation.

Do not panic if we try to dummynet an Ethernet packet that's not IPv4 or
IPv6. Simply give it to dummynet.

OpenVPN uses IPv4-mapped IPv6 addresses by default (if we don't specify
'proto udp4', or an IPv4 address to bind to). Test that this works.

Instead of returning EMSGSIZE pass the error code from fdallocn() directly
to userland. That would be EMFILE, which makes much more sense. This
error code is not listed in the specification[1], but the specification
doesn't cover such edge case at all. Meanwhile the specification lists
EMSGSIZE as the error code for invalid value of msg_iovlen, and FreeBSD
follows that, see sys_recmsg(). Differentiating these two cases will make
a developer/admin life much easier when debugging.

Most test pass identically on different kinds of sockets. However,
few edge cases work differently on stream and datagram sockets. We
want to exercise this and document.
Differential revision: https://reviews.freebsd.org/D35420
A one-to-many unix/dgram socket is a socket that has been bound
with bind(2) and can get multiple connections. A typical example
is /var/run/log bound by syslogd(8) and receiving multiple
connections from libc syslog(3) API. Until now all of these
connections shared the same receive socket buffer of the bound
socket. This made the socket vulnerable to overflow attack.
See 240d5a9b1c for a historical attempt to workaround the problem.
This commit creates a per-connection socket buffer for every single
connected socket and eliminates the problem. The new behavior will
optimize seldom writers over frequent writers. See added test case
scenarios and code comments for more detailed description of the
new behavior.

If ktls.require_ifnet is set to true, then check the TLS offload mode
for tests sending and receiving records and skip the test if the
offload mode is not ifnet mode.
This can be used along with ktls.host to run KTLS tests against a NIC
supporting ifnet TLS and verify that expected cipher suites and
directions used ifnet TLS rather than software TLS. Receive tests may
result in a false positive as receive ifnet TLS can use software as a
fallback.

Previously ktls tests always executed over a local socket pair.
ktls.host can be set to a host to connect to with a single socket
instead. The remote end is expected to echo back any data received
(such as the echo service). The port can be set with ktls.port which
defaults to "echo".
This is primarily useful to permit testing NIC TLS offload use cases
where the traffic needs to transit the NIC.
Note that the variables must be set via
'kyua -v test_suites.FreeBSD.ktls.host=host'.

some checks are unnecessary, while they actually were necessary.
While here, handle an edge case found by Mark, when on 64-bit platform

Put some data into a socket and check that:
o select(2) sees readable data
o kevent(2) sees data, and correctly sees data size
o ioctl(FIONREAD) sees correct size
o aio(4) successfully reads the data
Repeat the test twice for a connected socket and not-connected. With
future implementation these two cases would exercise different code.
We could insert proxy NDP entries by the ndp command, but the host
with proxy ndp entries had not responded to Neighbor Solicitations.
Change the following points for proxy NDP to work as expected:
* join solicited-node multicast addresses for proxy NDP entries
in order to receive Neighbor Solicitations.
* look up proxy NDP entries not on the routing table but on the
link-level address table when receiving Neighbor Solicitations.

Just invoke the test program directly instead of trying to convert its
output to TAP format. The test suite is all or nothing; there's no way
to enumerate individual test cases, so there's no advantage in trying to
massage its output, and doing so throws away information that's useful
when diagnosing test failures.

One of the tests exposes the regression reported in PR 264131.
One test is disabled because FreeBSD does not support setting EV_ONESHOT
on an already-added periodic timer. Though, in this case the flag is
simply ignored, which isn't ideal.
One test is slightly modified to set EV_ADD when reconfiguring a
disabled timer per some commentary in PR 258412.
Ideally we would re-import the test suite from libkqueue but there is a
fair bit of divergence so this will require some effort. This just gets
us one small step closer while increasing test coverage.

This used to be a problem as traffic shaping wasn't done in the ethernet

where we hit the L3 code first and only then the L2 code.
