(cherry picked from commit 115e99630a317cab62c6f99e0461f6ce2c1edaf3)

We always have had stale interface entries in the ct_iface_map of nftables/
conntrack for any interface that once belonged to a VRF.
This commit will always clean the nftables interface map when the interface
is deleted from the system.

To reproduce:
set vrf name mgmt table '150'
set vrf name no-mgmt table '151'
set interfaces ethernet eth2 vrf 'mgmt'
commit
set interfaces ethernet eth2 vrf no-mgmt
commit
This resulted in an error while interacting with nftables:
[Errno 1] failed to run command: nft add element inet vrf_zones ct_iface_map { "eth2" : 151 }
The reason is that the old mapping entry still exists and was not removed.
This commit adds a new utility function get_vrf_tableid() and compares the
current and new VRF table IDs assigned to an interface. If the IDs do not
match, the nftables ct_iface_map entry is removed before the new entry is added.

`bridge vni show dev vxlanX` will exit with an error if no VNI filters
are installed, but the getter is used even when we haven't installed any.
This fix avoids fetching a list of VNI filters unless we know we've
created some.

Add abiilty to change `base_reachable_time_ms` option
/proc/sys/net/ipv6/neigh/{ifname}/base_reachable_time_ms

If we use rfc3768-compatibility with long interface names like
eth1.100.200 it converts the VRRP interface name name
to `<interface>v<VRID><IP version>`
For example `eth2.100.200v10v4`
The limit for interface name is 15 symbols and it causes that
interface name is ignoring by keepalived
VMAC interface name 'eth2.100.200v10v4' too long or invalid characters - ignoring
And it uses the default prefix `vrrp` for such cases.
It works fine, but such interfaces are not displayed in the op-mode
Allow prefix `vrrp` for the op-mode for `show interfaces`

After migrating from ISC DHCLIENT for IPv6 to wide-dhcp-client the logic which
was present to update /etc/resolv.conf with the DHCP specified nameservers and
also the search domain list was no longer present.
This commit adds a per interface rendered script to inform vyos-hostsd about
the received IPv6 nameservers and search domains.
|
|
This reverts commit ab30509b25d54dac99294b76ba03fd49c3d2c946.
As in T6152 there seem to be some NICs that have a non working implementation
of reading the EEE registers. Remove this feature in the meantime until there
is a less exploding solution hindering boards to boot.
Return to Kernel defaults by removing this code path.

vti: T6085: interface is always down and only enabled by IPSec daemon
|
|
Linux bridge uses EtherType 0x8100 by default. In some scenarios, an EtherType
value of 0x88A8 is required.
Reusing CLI command from VIF-S (QinQ) interfaces:
set interfaces bridge br0 protocol 802.1ad
|
|
When a VTI interface is just created, it is in ADMIN UP state by default, even
if an IPSec peer is not connected. After the peer is disconnected the interface
goes to DOWN state as expected.
This breaks routing logic - for example, static routes through VTI interfaces
will be active even if a peer is not connected.
This changes to logic so ADMIN UP/DOWN state can only be changed by the
vti-up-down helper script.
Error was introduced during the Perl -> Python migration and move to the generic
vyos.ifconfig abstraction during the 1.4 development cycle.

Typo (missaligned -/_) in the code causes hw-tc-offload to never be enabled in
the underlaying hardware via ethtool.

We will use _ as CLI level divider. The XML definition filename and also
the Python helper should match the CLI node.
Example:
set interfaces ethernet -> interfaces_ethernet.xml.in
set interfaces bond -> interfaces_bond.xml.in
set service dhcp-server -> service_dhcp-server-xml.in
|
|
VyOS is a routing (packet pushing) platform, thus supporting EEE which
potentially causes issues is not a good idea. Some recent Intel drivers enable
EEE by default, thus we will disable this for every NIC supporting EEE.
|
|
The current implementation is wrong as it searches `master` in the
iproute2 JSON output. It is a worng as it could include bridges
or bonding interfaces
Add the more strict search `info_slave_kind == vrf`

vxlan: T5753: add support for VNI filtering
|
|
|
|
In a service provider network a service provider typically supports multiple
bridge domains with overlapping vlans. One bridge domain per customer. Vlans in
each bridge domain are mapped to globally unique VXLAN VNI ranges assigned to
each customer.
Without the ability of VNI filtering, we can not provide VXLAN tunnels
with multiple tenants all requiring e.g. VLAN 10.
To Test:
set interfaces vxlan vxlan987 parameters external
set interfaces vxlan vxlan987 source-interface eth0
set interfaces vxlan vxlan987 parameters vni-filter
set interfaces vxlan vxlan987 vlan-to-vni 50 vni 10050
set interfaces vxlan vxlan987 vlan-to-vni 51 vni 10051
set interfaces vxlan vxlan987 vlan-to-vni 52 vni 10052
set interfaces vxlan vxlan987 vlan-to-vni 53 vni 10053
set interfaces vxlan vxlan987 vlan-to-vni 54 vni 10054
set interfaces vxlan vxlan987 vlan-to-vni 60 vni 10060
set interfaces vxlan vxlan987 vlan-to-vni 69 vni 10069
set interfaces bridge br0 member interface vxlan987
Add new op-mode command: show bridge vni
Interface VNI
----------- -----------
vxlan987 10050-10054
vxlan987 10060
vxlan987 10069

Changing the public key of a peer (updating the key material) left the old
WireGuard peer in place, as the key removal command used the new key.
WireGuard only supports peer removal based on the configured public-key, by
deleting the entire interface this is the shortcut instead of parsing out all
peers and removing them one by one.
Peer reconfiguration will always come with a short downtime while the WireGuard
interface is recreated.

vxlan: T5668: add CLI knob to enable ARP/ND suppression
|
|
As we have a bunch of options under "paramteres" already and "external" is
clearly one of them it should be migrated under that node as well.
|
|
In order to minimize the flooding of ARP and ND messages in the VXLAN network,
EVPN includes provisions [1] that allow participating VTEPs to suppress such
messages in case they know the MAC-IP binding and can reply on behalf of the
remote host. In Linux, the above is implemented in the bridge driver using a
per-port option called "neigh_suppress" that was added in kernel version 4.15.

If ethernet interface is a bond memeber:
1. Allow for changing only specific parameters which are specified
in EthernetIf.get_bond_member_allowed_options function.
2. Added inheritable parameters from bond interface to ethernet
interface which are scpecified
in BondIf.get_inherit_bond_options.
Users can change inheritable options under ethernet interface
but in commit it will be copied from bond interface.
3. All other parameters are denied for changing.
Added migration script. It deletes all denied parameters under
ethernet interface if it is a bond member.

supports HW flowtable offload
- Add required offload setting for interfaces + flowtable offload (hw-tc-offload)
- Verification of interface support for hardware offloaded flowtables

FRR supports a new way of configuring VLAN-to-VNI mappings for EVPN-VXLAN, when
working with the Linux kernel. In this new way, the mapping of a VLAN to a VNI
is configured against a container VXLAN interface which is referred to as a
'Single VXLAN device (SVD)'.
Multiple VLAN to VNI mappings can be configured against the same SVD. This
allows for a significant scaling of the number of VNIs since a separate VXLAN
interface is no longer required for each VNI.
Sample configuration of SVD with VLAN to VNI mappings is shown below.
set interfaces bridge br0 member interface vxlan0
set interfaces vxlan vxlan0 external
set interfaces vxlan vxlan0 source-interface 'dum0'
set interfaces vxlan vxlan0 vlan-to-vni 10 vni '10010'
set interfaces vxlan vxlan0 vlan-to-vni 11 vni '10011'
set interfaces vxlan vxlan0 vlan-to-vni 30 vni '10030'
set interfaces vxlan vxlan0 vlan-to-vni 31 vni '10031'

wireguard: T5409: Added 'set interfaces wireguard wgX threaded'
|
|
Using threaded as CLI node is a very deep term used by kernel threads. To make
this more understandable to users, rename the node to per-client-thread.
It's also not necessary to test if any one peer is configured and probing if
the option is set. There is a base test which requires at least one peer
to be configured.
