conntrack: T5571: Refactor conntrack using vyos.configdep
|
|
- Moves MSS node out of `tcp-flags.xml.i` and into `tcp-mss.xml.i`
- Update smoketest to verify TCP flag matching

After commit 0ccbbca01b ("openvpn: T3214: specify nopool on --server line only
if needed") that removed the net30 option and nopool smoketests needed a fix.

T4502: firewall: Add software flow offload using flowtable

T5518: Add basic MLD support

Cleanup nets for the smoketest load-balancing
Remove deleting container interfaces from default netns as those
interfaces leave inly in netns.

The following commands will enable nftables flowtable offload on interfaces eth0 eth1:
```
set firewall global-options flow-offload software interface <name>
set firewall global-options flow-offload hardware interface <name>
```
Generated nftables rules:
```
table inet vyos_offload {
flowtable VYOS_FLOWTABLE_software {
hook ingress priority filter - 1; devices = { eth0, eth1, eth2, eth3 };
counter
}
chain VYOS_OFFLOAD_software {
type filter hook forward priority filter - 1; policy accept;
ct state { established, related } meta l4proto { tcp, udp } flow add @VYOS_FLOWTABLE_software
}
}
```
Use this option to count packets and bytes for each offloaded flow:
```
set system conntrack flow-accounting
```
To verify a connection is offloaded, run
```
cat /proc/net/nf_conntrack|grep OFFLOAD
```

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'

T4072: add firewall bridge filtering.
|
|
Currently VyOS has `protocol igmp` option to enable IGMP querier and reports through FRR's pimd.
I would like to add support for IPv6 as well since FRR's IPv6 multicast functionality has significantly improved.
Enabling both MLD and IGMP on a VyOS router will allow us to turn on multicast snooping on layer-3 switches in dual-stack networks.
Example commands:
```
// Enable on interface eth0
set protocols pim6 interface eth0
// Explicitly join multicast group ff18::1234 on interface eth1
set protocols pim6 interface eth1 mld join ff18::1234
// Explicitly join source-specific multicast group ff38::5678 with source address 2001:db8::1 on interface eth1
set protocols pim6 interface eth1 mld join ff38::5678 source 2001:db8::1
```

forward chain and few matchers. Should be extended in the future.

conntrack: T4309: T4903: Refactor `system conntrack ignore`, add IPv6 support and firewall groups

- Migrate IPv4 source-validation to nftables
- Interface source-validation value takes priority, fallback to global value

Commit 6896aabb6 ("wireless: T5540: fix VHT capability settings for 802.11ac"
changed how the VHT channel-sidth is configured in hostapd - but smoketests
did not get adjusted.

Configuring "set system ip protocol ospf|bgp route-map foo" and commit it
installs the route-map into FRR. Removing the CLI configuration "delete system
ip protocol" does not remove the route-map from FRR - it stays active.
This commit adds the fix and appropriate smoketests extenstion.

T5447: Initial support for MACsec static keys
|
|
|
|
Station MAC address-based authentication means:
* 'allow' accept all clients except the one on the deny list
* 'deny' accept only clients listed on the accept list
New CLI commands:
* set interfaces wireless wlan0 security station-address mode <accept|deny>
* set interfaces wireless wlan0 security station-address accept mac <mac>
* set interfaces wireless wlan0 security station-address deny mac <mac>

This fixes a CLI typo added in commit 77ef9f800 ("T5466: L3VPN label allocation
mode").
|
|
|
|
Commit 77ef9f800 ("T5466: L3VPN label allocation mode") added support for a new
CLI node that is added "label vpn export allocation-mode per-nexthop" to FRRs
running configuration. Unfortunately the smoketest contained a trailing
whitespace and the above mentioned line could not be evaluated to true.

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.

|
|
Testcases after the bugfix in commit 011697508 ("T5467: removing ospf(v3) or
isis interface in VRF context did not clear FRR config").
For ISIS change in the tests - do not run self_commit() in a for loop if not
really necessary, this will slow down the tests.
