Otherwise packet can be received in a VRF that was already deleted.
Image of the following CLI commands:
del interface ethernet eth0 address dhcp
del interface ethernet eth0 vrf red
del vrf name red
VRF could be deleted even if dhclient release was not yet completely
processed.

order to avoid empty value and problems when removing such parameters

|
set service dns dynamic timeout <60-3600>

There is no dhclient process running in given VRF. dhclient complains it can
not send out packets via the given interface (as it's not bound to that VRF)
Aug 02 20:29:54 dhclient[1686]: send_packet: Network is unreachable
Aug 02 20:29:54 dhclient[1686]: send_packet: please consult README file regarding broadcast address.

When no-release is specified, dhcp6c client will not release allocated address or prefix on client exit.

Fix template do not add interfaces with 'disable' option to the
lldp.conf
|
|
Fixed setting vrrp version
|
|
There was no /var/log/messages handler for logrotate making rsyslog
crash after a few days.
In addition we had some JIna2 templating errors for hosts, user and file
CLI nodes
jinja2.exceptions.UndefinedError: 'dict object' has no attribute 'facility'
Looks like therey are used rarely ;) - lucky me!

bgp: T5338: Added 'protocols bgp interface <int> mpls forwarding' feature
|
|
Added 'protocols bgp interface <int> mpls forwarding' feature.
It is possible to permit BGP install VPN prefixes without transport labels.
This configuration will install VPN prefixes originated from an e-bgp session,
and with the next-hop directly connected.

Migrate:
high-availability virtual-server 203.0.113.1
to: high-availability virtual-server <name> address 203.0.113.1

- changed memory requirement from total to available. This allows to start on
systems with less total memory and protects from startup on systems with
overloaded memory.
- prevent startup if sysctl settings were not applied. This protects from
situations when the system cannot allocate enough hugepages or apply other
sysctl settings.

T5333: Set prefix UD for PBR generated user-defined chain names
|
|
* set protocols ospf aggregation timer <seconds>
* set protocols ospf summary-address x.x.x.x/x [tag 1-4294967295]
* set protocols ospf summary-address x.x.x.x/x no-advertise
|

We cannot use some specific names like POSTROUTING/PREROUTING
as for PBR they overlaps with VyOS defined chains
Chains aftoconfigured by VyOS itself:
chain VYOS_PBR_PREROUTING
chain VYOS_PBR_POSTROUTING
If we try to use chain name "POSTROUTING" it generates 2 chains
with the same name "chain VYOS_PBR_POSTROUTING" one is
autoconfigured and the second defined by user
set policy route POSTROUTING rule 100
Add the user-defined (UD) prefix to separate user defined names
That allows to use any user-defined names

Do not allow configure VPP if on the systems with low amount
installed memory
Add sysctl VPP parameters (hugepages, kernel.shmmax)
|

T1797: Add initial vpp configuration
|
|
Add initial configuration mode for VPP (PoC)
set vpp cpu corelist-workers '2'
set vpp cpu main-core '1'
set vpp interface eth1 num-rx-desc '256'
set vpp interface eth1 num-rx-queues '512'
set vpp interface eth1 num-tx-desc '256'
set vpp interface eth1 num-tx-queues '512'
set vpp interface eth1 pci '0000:02:00.0'
set vpp interface eth1 rx-mode 'polling'
set vpp interface eth2 pci '0000:08:00.0'
Limitation:
- 'set vpp interface ethX pci auto' works only per first
commit, then interface detached from default stack and creates
tun interface 'ethX' to communicate with default stack. In this
case we can't get PCI address via ethtool for 'tun' interfaces.
But we can set pci address manualy.
- Interface sync between default stack and VPP-DPDK stack
After vpp change it doesn't trigger iproute2 for changes
(should be written later)
I.e. if we change something in vpp per each commit it restarts
vpp.service it gets empty interface config as we don't configure vpp
directly and it should be configured via iproute2
But then if we do any change on interface (for example description)
it gets IP address, MTU, state, etc.

- For option 'web', ddclient defaults to 'dyndns' which doesn't support
ssl. This results ddclient process lockup till connection to
checkip.dyndns.org:443 times out.
- For option 'use', ddclient defaults 'ip'. This results in confusing
message "WARNING: '' is not a valid IPv4 or IPv6 address" in log.
|
|
'PIDFile' option in 'Service' isn't multi-value and thus doesn't need
to be cleared before overriding.
|
|
Changes:
- Load generate 'avahi-daemon.conf' and validate basic configs
- Add tests for browsing domains and reflect-filter services
|
|
Templatize systemd override for ddclient service and move the generated
override files in /run. This ensures that the override files are always
generated afresh after boot.
Additionally, simplify the systemd override file by removing the
redundant/superfluous overrides.

Apply next round of configuration tree updates to 'service dns dynamic'
with the following changes:
- Migrate `service dns dynamic interface <interface> [use-web]`
to `service dns dynamic address <interface>`
or `service dns dynamic address web [web-options]`
This communicates the intent that dynamic dns IP address is detected
in only one way - using the `<interface>` or using an external web
request, not both.
- When using external web request, (`service dns dynamic address web`),
external url is optional (`web-options url`). Ddclient defaults are
used when unspecified,
- Rename all config `login` to `username` for consistency and also to
align better with alternative ddclient backends in consideration.
- Apply global 'ipv6-enable' to per service 'ip-version: ipv6'. Selecting
usage of IPv4 or IPv6 (or both simultaneously) is now at per service
(protocol) level instead of global level. This allows more control on
the ability to select IPv4 in some cases and IPv6 in some other cases
wherever supported by the underlying ddclient protocol.
- While the IP address (and by extension, the detection mechanism) is
global, the way it is applied to a particular ddclient protocol depends
on whether it supports IPv4 or IPv6 or both.
- Related to the above, this also prevents generating incorrect config
file (`ddclient.conf`) with multiple global sections leading to an
unpredictable behavior of ddclient.
- Implement provider (protocol) specific custom tweaks whenever possible
(e.g., `zone`, `username`, `server` are not necessary in all cases).
- Move service name from a combination of 'protocol' (with protocol
config autodetected) and custom (with protocol config specified) to a
single 'service' key. This allows for consisent setup of multiple
config for the same ddclient protocol (with different options and
credentials). This also avoid ambiguity with usual networking term
'protocol' and ddclient specific term 'protocol' (and can change with
a move to a different backend).
- Apply upfront XML constraints and validations consistently wherever
applicable.
- RFC2136 specific change: Rename rfc2136 config `record` to `host-name`
for consistency.
- Cloudflare specific change: While ddclient still supports authenticating
with email and global auth key, skipping `username` in config will
indicate the intent to use API token authentication (with special
'token' literal as `username`).

To accept a Proxy Protocol header on incoming TCP connections,
add an accept-proxy parameter to the bind line in a frontend section.
This parameter detects both Proxy Protocol version 1 (text format)
and Proxy Protocol version 2 (binary format).
