T4502: firewall: Add software flow offload using flowtable
|
|
- 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.

The `rule` key could be not exists in the entry of the dictionary
for examppe `{'default_action': 'drop'}`
Fix it

T5518: Add basic MLD support
|

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
```
This PR follows firewalld's implementation: https://github.com/firewalld/firewalld/blob/e748b97787d685d0ca93f58e8d4292e87d3f0da6/src/firewall/core/nftables.py#L590

container: T5563 Fix environment replaced by label
|
|
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'

T5554: Disable sudo for PAM RADIUS

Disable sudo for PAM RADIUS template that slows down the CLI commands
To fix it add:
session [default=ignore success=2] pam_succeed_if.so service = sudo

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
```

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.
