* Only matching flags and fields used by modern RFC2890 "extended GRE" -
this is backwards-compatible, but does not match all possible flags.
* There are no nftables helpers for the GRE key field, which is critical
to match individual tunnel sessions (more detail in the forum post)
* nft expression syntax is not flexible enough for multiple field
matches in a single rule and the key offset changes depending on flags.
* Thus, clumsy compromise in requiring an explicit match on the "checksum"
flag if a key is present, so we know where key will be. In most cases,
nobody uses the checksum, but assuming it to be off or automatically
adding a "not checksum" match unless told otherwise would be confusing
* The automatic "flags key" check when specifying a key doesn't have similar
validation, I added it first and it makes sense. I would still like
to find a workaround to the "checksum" offset problem.
* If we could add 2 rules from 1 config definition, we could match
both cases with appropriate offsets, but this would break existing
FW generation logic, logging, etc.
* Added a "test_gre_match" smoketest

T5873: ipsec remote access VPN: support VTI interfaces.

* PBR can only target table IDs up to 200 and the previous PR to extend the
range was rejected
* PBR with this PR can now also target VRFs directly by name, working around
targeting problems for VRF table IDs outside the overlapping 100-200 range
* Validation ensures rules can't target both a table ID and a VRF name
(internally they are handled the same)
* Added a simple accessor (get_vrf_table_id) for runtime mapping a VRF name
to table ID, based on vyos.ifconfig.interface._set_vrf_ct_zone().
It does not replace that usage, as it deliberately does not handle non-VRF
interface lookups (would fail with a KeyError).
* Added route table ID lookup dict, global route table and VRF table defs
to vyos.defaults. Table ID references have been updated in code touched
by this PR.
* Added a simple smoketest to validate 'set vrf' usage in PBR rules

(#3616)
* Change ipsec match-ipsec/none to match-ipsec-in and match-none-in for
fw rules
* Add ipsec match-ipsec-out and match-none-out
* Change all the points where the match-ipsec.xml.i include was used
before, making sure the new includes (match-ipsec-in/out.xml.i) are
used appropriately. There were a handful of spots where match-ipsec.xml.i
had snuck back in for output hooked chains already
(the common-rule-* includes)
* Add the -out generators to rendered templates
* Heavy modification to firewall config validators:
* I needed to check for ipsec-in matches no matter how deeply nested
under an output-hook chain(via jump-target) - this always generates
an error.
* Ended up retrofitting the jump-targets validator from root chains
and for named custom chains. It checks for recursive loops and improper
IPsec matches.
* Added "test_ipsec_metadata_match" and "test_cyclic_jump_validation"

Wireless devices are subject to regulations issued by authorities. For any
given AP or router, there will most likely be no case where one wireless NIC is
located in one country and another wireless NIC in the same device is located
in another country, resulting in different regulatory domains to apply to the
same box.
Currently, wireless regulatory domains in VyOS need to be configured per-NIC:
set interfaces wireless wlan0 country-code us
This leads to several side-effects:
* When operating multiple WiFi NICs, they all can have different regulatory
domains configured which might offend legislation.
* Some NICs need additional entries to /etc/modprobe.d/cfg80211.conf to apply
regulatory domain settings, such as: "options cfg80211 ieee80211_regdom=US"
This is true for the Compex WLE600VX. This setting cannot be done
per-interface.
Migrate the first found wireless module country-code from the wireless
interface CLI to: "system wireless country-code"

random - In kernel 5.0 and newer this is the same as fully-random. In earlier
kernels the port mapping will be randomized using a seeded MD5 hash mix using
source and destination address and destination port.

When all the underlay links go down the PE no longer has access to the VxLAN
+overlay.
To prevent blackholing of traffic the server/ES links are protodowned on the PE.
A link can be setup for uplink tracking via the following configuration:
set interfaces ethernet eth0 evpn uplink
