conntrack: T5376: T5598: Restore kernel conntrack helpers
|

ipsec: T5606: Add support for whole CA chains

Add option `protocol` for policy local-route
set policy local-route rule 100 destination '192.0.2.12'
set policy local-route rule 100 protocol 'tcp'
set policy local-route rule 100 set table '100'

`nf_conntrack_helper` that auto-assigned helpers is removed from the kernel
|
|
Also includes an update to smoketest to verify
|
|
Additional cleanup and refactoring for ddclient scripts including the
smotektests.
|
|
Enable TTL support for web-service based protocols in addition to
RFC2136 based (nsupdate) protocol.
Since TTL is not supported by all protocols, and thus cannot have a
configuration default, the existing XML snippet `include/dns/time-to-live.xml.i`
does not have common `<defaultValue>300</defaultValue>` anymore and is
instead added explicitly whenever necessary.
|
|
dyndns2 protocol in ddclient honors dual stack for selective servers
because of the way it is implemented in ddclient.
We formalize the well known servers that support dual stack in a list
and check against it when validating the configuration.
|
|
Fix VRF support interface definition and configuration mode for ddclient
to actually capture the VRF name and pass it to the template.
|
|
Add ability to SYNPROXY connections
It is useful to protect against TCP SYN flood attacks and port-scanners
set firewall global-options syn-cookies 'enable'
set firewall ipv4 input filter rule 10 action 'synproxy'
set firewall ipv4 input filter rule 10 destination port '22'
set firewall ipv4 input filter rule 10 inbound-interface interface-name 'eth1'

T5586: Disable by default SNMP for Keeplived VRRP service
|
|
T5261: Add AWS load-balancing tunnel handler
|
|
AgentX does not work stable. From time to time we see the system
service crashing/degrading if something is wrong with SNMP from
util net-snmp.
We should disable it by default and enable it only if configured.

ddclient: T5585: Fix file access mode for dynamic dns configuration
|
|
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.
|
|
ddclient.conf file is expected to have permission 600. We need to set
the permission explicitly while creating the file.

T4502: firewall: Add software flow offload using flowtable
|
|
In CLI we can choose authentication logic:
- `mandatory` - if TACACS+ answered with `REJECT`, authentication must be
stopped and access denied immediately.
- `optional` (default) - if TACACS+ answers with `REJECT`, authentication
continues using the next module.
In `mandatory` mode authentication will be stopped only if TACACS+ clearly
answered that access should be denied (no user in TACACS+ database, wrong
password, etc.). If TACACS+ is not available or other errors happen, it will be
skipped and authentication will continue with the next module, like in
`optional` mode.

In CLI we can choose authentication logic:
- `mandatory` - if RADIUS answered with `Access-Reject`, authentication must
be stopped and access denied immediately.
- `optional` (default) - if RADIUS answers with `Access-Reject`,
authentication continues using the next module.
In `mandatory` mode authentication will be stopped only if RADIUS clearly
answered that access should be denied (no user in RADIUS database, wrong
password, etc.). If RADIUS is not available or other errors happen, it will be
skipped and authentication will continue with the next module, like in
`optional` mode.

while configuring dNAT|sNAT rule
|
|
- 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.

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'

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
```

T5480: Ability to disable SNMP for keepalived service VRRP
|

When using `virtual-server` alongside Keepalived, there can be
situations where the `vrrp` key is completely unused.
