srv6: T591: enable SR enabled packet processing on defined interfaces
|
|
T2898: add ndp-proxy service
|
|
The DUID regex was missing a lower bound, which could cause it not to
match when it should.
We have to specify the lower bound explicitly as 0 to keep the regex
behavior similar to that in Python (in Python, omitting the lower bound
is equivalent to specifying 0).
|
|
|
|
Refactor DUID XML definition in conf-mode to be reusable. Additionally, remove
explicit call to a separate validator `ipv6-duid` and inline the regex into the
XML definition.

VyOS CLI command
set service ndp-proxy interface eth0 prefix 2001:db8::/64 mode 'static'
Will generate the following NDP proxy configuration
$ cat /run/ndppd/ndppd.conf
# autogenerated by service_ndp-proxy.py
# This tells 'ndppd' how often to reload the route file /proc/net/ipv6_route
route-ttl 30000
# This sets up a listener, that will listen for any Neighbor Solicitation
# messages, and respond to them according to a set of rules
proxy eth0 {
# Turn on or off the router flag for Neighbor Advertisements
router no
# Control how long to wait for a Neighbor Advertisment message before invalidating the entry (milliseconds)
timeout 500
# Control how long a valid or invalid entry remains in the cache (milliseconds)
ttl 30000
# This is a rule that the target address is to match against. If no netmask
# is provided, /128 is assumed. You may have several rule sections, and the
# addresses may or may not overlap.
rule 2001:db8::/64 {
static
}

The Linux Kernel needs to be told if IPv6 SR enabled packets whether should be
processed or not. This is done using
/proc/sys/net/conf/<iface>/seg6_* variables:
seg6_enabled - BOOL
Accept or drop SR-enabled IPv6 packets on this interface.
Relevant packets are those with SRH present and DA = local.
0 - disabled (default)
not 0 - enabled
Or the VyOS CLI command:
* set protocols segment-routing interface eth0 srv6

frr: T4020: add option to define number of open file descriptors
|
|
This allows the operator to control the number of open file descriptors each
daemon is allowed to start with. The current assumed value on most operating
systems is 1024.
If the operator plans to run bgp with several thousands of peers then this is
where we would modify FRR to allow this to happen.

T4163: Add BGP Monitoring Protocol BMP feature
|
|
T5798: load-balancing revese-proxy add multiple SSL certificates
|
|
Add BMP feature.
BMP (BGP Monitoring Protocol, RFC 7854) is used to send monitoring
data from BGP routers to network management entities
https://docs.frrouting.org/en/latest/bmp.html
Example:
set system frr bmp
commit
run restart bgp
set protocols bgp system-as '65001'
set protocols bgp neighbor 192.0.2.11 address-family ipv4-unicast
set protocols bgp neighbor 192.0.2.11 remote-as '65001'
set protocols bgp bmp mirror-buffer-limit '256000000'
set protocols bgp bmp target foo address '127.0.0.1'
set protocols bgp bmp target foo port '5000'
set protocols bgp bmp target foo min-retry '1000'
set protocols bgp bmp target foo max-retry '2000'
set protocols bgp bmp target foo mirror
set protocols bgp bmp target foo monitor ipv4-unicast post-policy
set protocols bgp bmp target foo monitor ipv4-unicast pre-policy
set protocols bgp bmp target foo monitor ipv6-unicast post-policy
set protocols bgp bmp target foo monitor ipv6-unicast pre-policy

dhcp: T3316: Migrate dhcp/dhcpv6 server to Kea
|
|
Apply baseline defaults for `.gitattributes` and `.vscode/settings.json`
for improved developer experience.
The `.gitattrbutes` settings are based on:
Git documentation (https://git-scm.com/docs/gitattributes#_effects)
GitHub documentation (https://docs.github.com/en/get-started/getting-started-with-git/configuring-git-to-handle-line-endings)
Community templates (https://github.com/gitattributes/gitattributes)
Since editor-agnostic line-ending specific settings are applied to
`.gitattributes`, they can be removed from `.vscode/settings.json`.
The global VSCode defaults have also been removed to avoid duplication.

T5775: firewall: re-add state-policy to firewall. These commands are …
|
|
- Update the base (rebase)
- Move include/nat64-protocol.xml.i => include/nat64/protocol.xml.i
- Delete unwanted `write_json`, use `write_file` instead
- Remove unnecessary deleting of default values for tagNodes T2665
- Add smoketest
Example:
```
set interfaces ethernet eth0 address '192.168.122.14/24'
set interfaces ethernet eth0 address '192.168.122.10/24'
set interfaces ethernet eth2 address '2001:db8::1/64'
set nat64 source rule 100 source prefix '64:ff9b::/96'
set nat64 source rule 100 translation pool 10 address '192.168.122.10'
set nat64 source rule 100 translation pool 10 port '1-65535'
```

accel-ppp: T5688: Standardized pool configuration in accel-ppp
|
|
Standardized pool configuration for all accel-ppp services.
1. Only named pools are used now.
2. Allows all services to use range in x.x.x.x/mask
and x.x.x.x-x.x.x.y format
3. next-pool can be used in all services
2. Allows to use in ipoe gw-ip-address without pool configuration
which allows to use Fraimed-IP-Address attribute by radius.
3. Default pool name should be explicidly configured
with default-pool.
4. In ipoe netmask and range subnet can be different.

ddclient: T5791: Update dynamic dns configuration path for consistency
|
|
policy: T4704: Allowed to set metric (MED) to (+/-)rtt
|
|
|
|
As followup to interface definition change, remove XML snippets that
aren't used anymore. They were there because they were 'include'-ed
multiple times in the interface definition `dynamic-dns.xml.in`. Since
that's not the case anymore, they can be removed.
|
|
Modify the configuration path to be consistent with the usual dialects
of VyoS configuration (wireguard, dns, firewall, etc.)
This would also shorten the configuration path and have a unified
treatment for RFC2136-based updates and other 'web-service' based updates.
While at it, add support for per-service web-options. This would allow
for probing different external URLs on a per-service basis.

Allowed to set metric (MED) to (+/-)rtt in the route-map.

T5637: firewall: extend rule for default-action to firewall bridge
|
|
pppoe: T5630: make MRU default to MTU if unspecified
|
|
to be able to catch logs using separte rule for default-action
|
|
This fixes the implementation in e062a8c11 ("pppoe: T5630: allow to specify MRU
in addition to already configurable MTU") and restores the bahavior that MRU
defaults to MTU if MRU is not explicitly set.
This was the behavior in VyOS 1.3.3 and below before we added ability to define
the MRU value.

Found an odd behavior on Linux and the VyOS CLI implementation. If adding VXLAN
interfaces using iproute2 the MTU differs depending on the creation syntax:
ip -4 link add vxlan100 type vxlan dstport 4789 external df unset tos inherit \
ttl 16 nolearning vnifilter local 172.16.33.201
ip -4 link add vxlan200 type vxlan id 200 dstport 4789 local 172.16.33.201 dev eth0
ip -6 link add vxlan300 type vxlan id 300 dstport 4789 local 2001:db8:1::1 dev eth0
132: vxlan300: <BROADCAST,MULTICAST> mtu 1430 qdisc noop state DOWN group default qlen 1000
link/ether 4e:fb:e3:f5:d9:59 brd ff:ff:ff:ff:ff:ff
133: vxlan200: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN group default qlen 1000
link/ether 0e:4e:f4:76:59:3f brd ff:ff:ff:ff:ff:ff
134: vxlan100: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether ba:b6:b7:0c:b1:37 brd ff:ff:ff:ff:ff:ff
VyOS always sets a default MTU of 1450 bytes which is correct for IPv4 p2p links
or multicast, but invalid for IPv6 p2p. Also this will break EVPN deployments
as ethernet bridges with MTU < 1500 bytes are less fun.
Increase default MTU to 1500 bytes. Migrate old configurations to use 1450
bytes if not specified otherwise on the CLI.

vxlan: T5753: add support for VNI filtering
|
|
This complements commit f5e43b136 ("http: T5762: api: make API socket backend
communication the one and only default") so we have a consistent port CLI node
across VyOS components.

|
http: T5762: api: make API socket backend communication the one and only default
|
|
Why: Smoketests fail as they can not establish IPv6 connection to uvicorn
backend server.
https://github.com/vyos/vyos-1x/pull/2481 added a bunch of new smoketests.
While debugging those failing, it was uncovered, that uvicorn only listens on
IPv4 connections
vyos@vyos# netstat -tulnp | grep 8080
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN -
As the CLI already has an option to move the API communication from an IP to a
UNIX domain socket, the best idea is to make this the default way of
communication, as we never directly talk to the API server but rather use the
NGINX reverse proxy.
