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.

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.

The current named for certificates are hardcoded in generated config to:
- ca.pem
- cert.pem.key
- cert.pem
It cause a generated config certificates and certificates itself
are different (test-cert-1.pem and ca.pem)
bind :::8080 v4v6 ssl crt /run/haproxy/test-cert-1.pem
/run/haproxy/ca.pem
It is a bug of initial impelemtation. Fix required correct names
from PKI certificates

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.

T5165: Implement policy local-route source and destination port (backport #2342)
|
|
pmacct daemons have one very important specific - they handle control signals in
the same loop as packets. And packets waiting is blocking operation.
Because of this, when systemctl sends SIGTERM to uacctd, this signal has no
effect until uacct receives at least one packet via nflog. In some cases, this
leads to a 90-second timeout, sending SIGKILL, and improperly finished tasks.
As a result, a working folder is not cleaned properly.
This commit contains several changes to fix service issues:
- add a new nftables table for pmacct with a single rule to get the ability to
send a packet to nflog and unlock uacctd
- remove PID file options from the uacctd and a systemd service file. Systemd
can detect proper PID, and PIDfile is created by uacctd too late, which leads
to extra errors in systemd logs
- KillMode changed to mixed. Without this, SIGTERM is sent to all plugins and
the core process exits with status 1 because it loses connection to plugins too
early. As a result, we have errors in logs, and the systemd service is in a
failed state.
- added logging to uacctd
- systemctl service modified to send packets to specific address during a service
stop which unlocks uacctd and allows systemctl to finish its work properly

During system startup the system-login.py script is invoked by vyos-router
systemd service. As there is no complete configuration available at this
point in time - and the sole purpose of this call is to reset/re-render
the system NSS/PAM configs back to default - it accidently also deleted the
local useraccounts.
Once the VyOS configuration got mounted, users got recreated in alphabetical
order and thus UIDs flipped and the /home suddenely belonged to a different
account.
This commit prevents any mangling with the local userdatabase during VyOS
bootup phase.

This commit adds a new configuration option to the mDNS repeater service
to allow controlling which IP version to use for mDNS repeater.
Additionally, publishing AAAA record over IPv4 and A record over IPv6 is
disabled as suggested.

AgentX does not work stable. From time to time we see the system

util net-snmp.
We should disable it by default and enable it only if configured.

After commit 976f82785 ("T5575: ARP/NDP table-size isnt set properly") the
system bootup process got interrupted as both system-ip.py and system-ipv6.py
tried to talk to FRR which was yet not started.
This has been fixed by using a conditional path to only execute when FRR service
has been enabled. This is safe to do as the initial commit call will has FRR
service running and the path will be executed.

T5480: Ability to disable SNMP for keepalived service VRRP
|
|
- Reuse existing utility functions to check if a boot is ongoing
(boot_configuration_complete())
- Run system_frr.py script to configure FRR daemon before initial launch
- Add safety net to always have FRR running on the system
This does yet not solve the error in T5239 but it's a small step towards
the solution.

T5533: Fix for vrrp dict key if virtual-server is used
|
|
(cherry picked from commit 79a46675b031a4edc0ea925a45066077c0804b9b)

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'

T5533: Fix VRRP IPv6 group enters in FAULT state
|
|
Checks if an IPv6 address on a specific network interface is
in the tentative state. IPv6 tentative addresses are not fully configured
and are undergoing Duplicate Address Detection (DAD) to ensure they are
unique on the network.

The following command expects to join source-specific multicast group 239.1.2.3
on interface eth0, where the source address is 192.0.2.1.
set protocols igmp interface eth0 join 239.1.2.3 source 192.0.2.1
This command should generate FRR config:
interface eth0
ip igmp
ip igmp join 239.1.2.3 192.0.2.1
exit
However, there is a bug in the Jinja template where `if ifaces[iface].gr_join[group]`
is mostly evaluated as `false` because `iface` is a loop variable from another loop.
