7a2bf4c52e pfctl: Don't retrieve interface list if '-n' is set
If '-n' is set we don't use the list of skip interfaces, so don't retrieve it.
This fixes issues if 'pfctl -n' is used before the pf module is loaded. This
was broken by r333181.

2d0730b243 Assuming that the intent (from the white space) is that the fprintf()
be executed in the if() conditional.  If its not supposed to be printed
inside the conditional, then the braces should be removed and the extra
tabs on the fprintf() should be removed.

150182e309 pf: Support "return" statements in passing rules when they fail.
Normally pf rules are expected to do one of two things: pass the traffic or
block it. Blocking can be silent - "drop", or loud - "return", "return-rst",
"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.

Allow users to configure this behaviour too, so that pf returns an error packet
in these cases.

fa1d4439f9 pf: Return non-zero from 'status' if pf is not enabled
In the pf rc.d script the output of `/etc/rc.d/pf status` or `/etc/rc.d/pf
onestatus` always provided an exit status of zero. This made it fiddly to
programmatically determine if pf was running or not.

Return a non-zero status if the pf module is not loaded, extend pfctl to have
an option to return an error status if pf is not enabled.

c5e105655b pfctl: Don't break connections on skipped interfaces on reload
On reload we used to first flush everything, including the list of skipped
interfaces.  This can lead to termination of these connections if they send
packets before the new configuration is applied.

Note that this doesn't currently happen on 12 or 11, because of special EACCES
handling introduced in r315514. This special behaviour in tcp_output() may
change, hence the fix in pfctl.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

58c8430a32 pfctl: teach route-to to deal with interfaces with multiple addresses
The route_host parsing code set the interface name, but only for the first
node_host in the list. If that one happened to be the inet6 address and the
rule wanted an inet address it'd get removed by remove_invalid_hosts() later
on, and we'd have no interface name.

We must set the interface name for all node_host entries in the list, not just
the first one.

4d7709ddf6 pfctl parser tests
Copy the most important test cases from OpenBSD's corresponding
src/regress/sbin/pfctl, those that run pfctl on a test input file and check
correctness of its output. We have also added some new tests using the same
format.

The tests consist of a collection of input files (pf*.in) and
corresponding output files (pf*.ok). We run pfctl -nv on the input
files and check that the output matches the output files. If any
discrepancy is discovered during future development in the source
tree, we know that a regression bug has been introduced into the tree.

allows to skip the in pfil hooks and completely removes the out pfil invoke,
albeit looking up a route that the IP stack will likely find on its own.

64b3b4d611 pf: Remove support for 'scrub fragment crop|drop-ovl'
The crop/drop-ovl fragment scrub modes are not very useful and likely to confuse

It's also a fairly large amount of complex code, so just remove the support
altogether.

Users who have 'scrub fragment crop|drop-ovl' in their pf configuration will be
implicitly converted to 'scrub fragment reassemble'.
