In order to move python2 out of the test framework to avoid py2 vs. py3
confusions upgrade the remaining test cases using scapy to work with py3.
That means only one version of scapy needs to be installed in the CI system.
It also gives a path forward for testing i386 issues observed in the CI
system with some of these tests.
Fixes are:
- Use default python from environment (which is 3.x these days).
- properly ident some lines as common for the rest of the file to avoid
errors.
- cast the calculated offset to an int as the division result is considered
a float which is not accepted input.
- when comparing payload to a magic number make sure we always add the
payload properly to the packet and do not try to compare string in
the result but convert the data payload back into an integer.
- fix print formating.

The change to conform to RFC 8200 for overlapping fragments now frees
the entire reassembly queue if the overlapping fragments are not an
exact match.
As a result we do see one less packet in the timeout statistics from
expiry. No other statistics change as the event is not counted.
It can be argued that we should improve the statistics counters in
that case.
This test case update should have been committed alongside the original
commit.

When we receive the packet with the first fragmented part (fragoff=0)
we remember the length of the unfragmentable part and the next header
(and should probably also remember ECN) as meta-data on the reassembly
queue.
Someone replying this packet so far could change these 2 (3) values.
While changing the next header seems more severe, for a full size
fragmented UDP packet, for example, adding an extension header to the
unfragmentable part would go unnoticed (as the framented part would be
considered an exact duplicate) but make reassembly fail.
So do not allow updating the meta-data after we have seen the first
fragmented part anymore.
The frag6_20 test case is added which failed before triggering an
ICMPv6 "param prob" due to the check for each queued fragment for
a max-size violation if a fragoff=0 packet was received.
MFC after: 3 weeks

When done with tests check that both the per-VNET and the global-fragmented-
packets-in-system counters are zero to make sure we do not leak counters or
queue entries.
This implies that for all test cases we either have to check for the ICMPv6
packet sent in case of TLL=0 expiry (if it is sent) or sleep at least long
enough for the TTL to expire for all packets (e.g., fragments where we do not
have the off=0 packet).
This also means that statistics are now updated to include all the expired
packets.
There are cases when we do not check for counters to be zero and this is
when testing VNET teardown to behave properly and not panic, when we are
intentionally leaving fragments in the system.
MFC after: 3 weeks
Sponsored by: Netflix
In order to ensure that changing the frag6 code does not change behaviour
or break code a set of test cases were implemented.
Like some other test cases these use Scapy to generate packets and possibly
wait for expected answers. In most cases we do check the global and
per interface (netstat) statistics output using the libxo output and grep
to validate fields and numbers. This is a bit hackish but we currently have
no better way to match a selected number of stats only (we have to ignore
some of the ND6 variables; otherwise we could use the entire list).
Test cases include atomic fragments, single fragments, multi-fragments,
and try to cover most error cases in the code currently.
In addition vnet teardown is tested to not panic.
A separate set (not in-tree currently) of probes were used in order to
make sure that the test cases actually test what they should.
The "sniffer" code was copied and adjusted from the netpfil version
as we sometimes will not get packets or have longer timeouts to deal with.

* Don't create a UFS mountpoint just to store some temporary files. The
tests should always be executed with a sufficiently large TMPDIR.
Creating the UFS mountpoint is not only unneccessary, but it slowed
zpool_import_missing_002_pos greatly, because that test moves large files
between TMPDIR and the UFS mountpoint. This change also allows many of
the tests to be executed with just a single test disk, instead of two.
* Move zpool_import_missing_002_pos's backup device dir from / to $PWD to
prevent cross-device moves. On my system, these two changes improved that
test's speed by 39x. It should also prevent ENOSPC errors seen in CI.

Add an atomic shm rename operation, similar in spirit to a file
rename. Atomically unlink an shm from a source path and link it to a
destination path. If an existing shm is linked at the destination
path, unlink it as part of the same atomic operation. The caller needs
the same permissions as shm_unlink to the shm being renamed, and the
same permissions for the shm at the destination which is being
unlinked, if it exists. If those fail, EACCES is returned, as with the
other shm_* syscalls.
truss support is included; audit support will come later.
This commit includes only the implementation; the sysent-generated
