T1237: Fix failover route install route with diff metrics
|
|
T4883: add a description field for routing tables
|
|
used
We need to ensure that source-address is assigned on source-interface before
applying the configuration, else SSH client will have a hard time talking to
someone.
|
|
|
|
Commit 846e306700a ("ssh: T2651: add cli options for source address") added
support for a basic SSH client option, but it grabbed the entire
/etc/ssh/ssh_config file without the ability to make custom user
adjustments via the /etc/ssh/ssh_config.d/ folder.
This vommit places the VyOS SSH options under /etc/ssh/ssh_config.d/ leaving
the common override system alive.
|
|
This makes transitions/updates faster and less error prone
|
|
|
|
If there is no route in the routing table (requires install route)
it checks routing table and returns best route None
But if we have 2 routes to the same dest ip but with different
metrics it doesn't get None (not first route install)
It cause that bast metric route cannot be installed (wrong logic)
Add func "is_route_exists" and check route/gateway/metric for
the required route

T4904: keepalived virtual-server allow multiple ports with fwmark
|
|
Add missing option "verbose" for op-mode NAT
|
|
|
|
Allow multiple ports for high-availability virtual-server
The current implementation allows balance only one "virtual" address
and port between between several "real servers"
Allow matching "fwmark" to set traffic which should be balanced
Allow to set port 0 (all traffic) if we use "fwmark"
Add health-check script
set high-availability virtual-server 203.0.113.1 fwmark '111'
set high-availability virtual-server 203.0.113.1 real-server 192.0.2.11 health-check script '/bin/true'
set high-availability virtual-server 203.0.113.1 real-server 192.0.2.11 port '0'

T4893: Add ppp-options ipv6-interface-id for L2TP
|
|
|
|
|
|
Add ppp-options IPv6 interface id for vpn L2TP
- fixed or random interface identifier for IPv6
- peer interface identifier for IPv6
- whether to accept peer’s interface identifier
set vpn l2tp remote-access ppp-options ipv6-accept-peer-intf-id
set vpn l2tp remote-access ppp-options ipv6-intf-id 'random'
set vpn l2tp remote-access ppp-options ipv6-peer-intf-id 'calling-sid'

`leaf_node_changed` returns `[]` (empty list) after a leaf node is
added.
e.g. Setting `source-interface` doesn't work on an existing vxlan
interface.
Steps to reproduce:
- Add a vxlan interface without `source-address` or `source-interface` options set:
```
set interfaces vxlan vxlan999 vni 999
set interfaces vxlan vxlan999 remote 192.168.100.100
commit
```
- Then set `source-address` or `source-interface`:
```
set interfaces vxlan vxlan999 source-interface eth0
commit
```
Actual result:
Source address or source-interface are not set:
```
ip -d link show dev vxlan999
76: vxlan999: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/ether 56:08:ba:4d:4e:a8 brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535
vxlan id 999 remote 192.168.100.100 srcport 0 0 dstport 8472 tos inherit ttl 16 ageing 300 udpcsum noudp6zerocsumtx noudp6zerocsumrx addrgenmode none numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535
```
Expected result:
```
77: vxlan999: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/ether 9e:05:d9:58:1a:af brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535

```
All invocations of leaf_node_changed() should be migrated to is_node_changes() if you are only interested in if something changed and don‘t care what exactly changed (content).

leaf_node_changed()
We only need to use leaf_node_changed() if we are interested in the detailed
change to a CLI node (what was the previous content). If we are only interested
in if a node changed "at all" is_node_changed() should be used.

Instead of hardcoding the default protocol as TCP in the Python script we shall
use the XML based defaultValue approach instead. This also automatically exports
the default to the CLI completion helper.
|

If port is specified on the CLI so must be source and destination under
the port node.

Commit 60c80df4 ("container: T4870: bump package version 0 -> 1 for filesystem
change") introduced a fundamental change in the container storage driver that
required a manual migration step from the user to not loose any data.
This commit removes the manual user interaction and temporary exports the
container images and re-imports them after the filesystem got changed. The only
things that get lost are orphaned container images no longer referenced by the
CLI - thats an adequate trade-off as those images can always be re-added to the
system.

move from vfs to overlay driver
The following pre iage upgrade script must be executed to have containers after
the reboot:
for pod in $(cli-shell-api listActiveNodes container name); do
systemctl stop vyos-container-${pod//\'}.service
done
sed -i 's/vfs/overlay/g' /etc/containers/storage.conf /usr/share/vyos/templates/container/storage.conf.j2
rm -rf /usr/lib/live/mount/persistence/container/storage/libpod
for pod in $(cli-shell-api listActiveNodes container name); do
image=$(cli-shell-api returnActiveValue container name ${pod//\'} image)
podman image pull $image
systemctl start vyos-container-${pod//\'}.service
done
for dir in vfs vfs-containers vfs-images vfs-layers; do
rm -rf /usr/lib/live/mount/persistence/container/storage/$dir
done

ipsec.py

|

Our python scripts use the shebang logic to set an intepreter - we should
rely on this and not use an external interpreter in front of the helper.

script
Sorting DHCP pools and filtering for state can now be done using the new op-mode
mode scripts in DHCP. This allows us to drop the old helpers show_dhcp.py and
show_dhcpv6.py.
|
|
script
Remaining functionality to filter NAT translations for a given address
got implemented to nat.py - with this cahnge we can drop the old files
show_nat*.py

Fixed op_mode show conntrack table ipv4

T4866: rewrite show_interfaces.py show* functions to standardized op-mode

Migration for "remote-id" where peer is IPv4 or IPv6 address
was missed
It was only migration if peer starts with "@"
It cause that you must manualy set 'remote-id' to get it working
correctly
replace 'vpn ipsec site-to-site peer 192.0.2.2'
=> 'vpn ipsec site-to-site peer peer_192-0-2-2 authentication remote-id 192.0.2.2'
|
|
|
|
As the script itself (vpn_ipsec.py) is already invoked using sudo, there is no
further need to also call sudo inside the script again.
|
|
|
|
As the API daemon has the proper permissions and also the CLI op-mode calls the
script already with "sudo", there is no need to call "sudo" inside this script,
again.
|
|
The implementation of is_node_changed() is less error prone and should always
be favoured.

T4780: Firewall: add firewall groups in firewall. Extend matching cri…

login: T4751: 2FA OTP key generator in VyOS CLI
|
|
1. Added in script update webproxy blacklists generation of all DBs
2. Fixed: if the blacklist category does not have generated db,
the template generates an empty dest category
in squidGuard.conf and a Warning message.
3. Added template generation for local's categories
in the rule section.
4. Changed syntax in the generation dest section for blacklist's
categories
4. Fixed generation dest local sections in squidGuard.conf
5. Fixed bug in syntax. The word 'allow' changed to the word 'any'
in acl squidGuard.conf

routing: T1237: Add new feature failover route
|
|
There was a mistake in a config level that caused triggering the
`shutdown_required` flag, even if there were no new interfaces added to a
bonding.
This commit sets the proper config level to avoid the problem.
|

Failover route allows to install static routes to the kernel routing
table only if required target or gateway is alive
When target or gateway doesn't respond for ICMP/ARP checks this route
deleted from the routing table
Routes are marked as protocol 'failover' (rt_protos)
cat /etc/iproute2/rt_protos.d/failover.conf
111 failover
ip route add 203.0.113.1 metric 2 via 192.0.2.1 dev eth0 proto failover
$ sudo ip route show proto failover
203.0.113.1 via 192.0.2.1 dev eth0 metric 1
So we can safely flush such routes
