Checks if an IPv6 address on a specific network interface is
in the tentative state. IPv6 tentative addresses are not fully configured
and are undergoing Duplicate Address Detection (DAD) to ensure they are
unique on the network.
inet6 2001:db8::3/125 scope global tentative
It tentative state the group enters in FAULT state. Fix it.

This is a workaround for the priority inversion from T5492 ("CLI node priority
is not inversed on node deletion"). As this is a corner case bug that's only
triggered if an interface is removed from a VRF and also the VRF is removed in
one commit, priorities are not honored.
Thus we implement this workaround which stop the DHCP(v6) client processes on
the VRF associated interfaces to get out the DHCP RELEASE message before
interfaces are shut down.

T5506: Add link-local IPv6 address for container interfaces

Add interface type veth (Virtual ethernet)
One of the usecases it's interconnect different vrf's and
default vrf via bridge
set interfaces virtual-ethernet veth0 peer-name 'veth1010'
set interfaces virtual-ethernet veth1010 address '10.0.0.10/24'
set interfaces virtual-ethernet veth1010 peer-name 'veth0'
set interfaces virtual-ethernet veth1010 vrf 'foo'
set interfaces bridge br0 address '10.0.0.1/24'
set interfaces bridge br0 member interface veth0
vyos@r1:~$ ping 10.0.0.10 count 1

Sshguard protects hosts from brute-force attacks
It can inspect logs and block "bad" addresses by threshold
Auto-generates own tables and rules for nftables, so they are not

When service stops, all generated tables are deleted.

Users might add the podman network interface to a zone based firewall. This
could cuase breaking configs on upgrades to 1.4.
As container support is not yet released for 1.3 LTS version (will be 1.3.3),
we once rename the network interface to match the schema in VyOS 1.4.

T4727: Add RADIUS rate-limit attribute for vpn pptp

Fix for Telegraf agent hostname isn't qualified
Try to get the hostname from FQDN and then from the hostname
Used for metrics
You may have more than one machine with different domain names
r1 domain-name foo.local, hostname myhost
r2 domain-name bar.local, hostname myhost
It helps to detect from which exactly host we get metrics for

Commit 52e51ffb ("container: T5047: restart only containers that changed")
started to iterate over a NoneType which is invalid. This happened when a
network description was changed but no container was due for restart.

By default VyOS used to restart all containers it managed. This makes no sense
as it will be service disrupting. Instead only restart the containers that had
changes on the CLI beeing made.

openconnect: T4955: Removed wrong authserver in radiusclient.conf
|
|
As we have the same variable name 'default_values' for container
name, port and volume, it rewrites default container parameters
with default port parameters
Fix it

This reverts commit 7b36c363cd5b0168bd83c399f50a0a360ba3ee58.
A general solution is implemented in Commit ae9dde04 ("T4975: always sync()
filesystem after commit").
|

User profile files are not saved to disk after configuration is fully applied.
Because of this, after a fast system reset, profile files can be empty, and CLI
is broken.
This fix adds a `sync()` call after the user's configuration, which should
protect from data loss and fix the problem with profiles.

Whenever a container is used and a folder is mounted, this happenes as
read-write which is the default in Docker/Podman - so is the default in VyOS.
A new option is added "set container name foo volume mode <ro|rw>" to specify
explicitly if rw (default) or ro should be used for this mounted folder.

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 commit places the VyOS SSH options under /etc/ssh/ssh_config.d/ leaving
the common override system alive.

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
5. Fixed generation dest local sections in squidGuard.conf
6. Fixed bug in syntax. The word 'allow' changed to the word 'any'
in acl squidGuard.conf

When any configured peer is set to `disable` while the Wireguard tunnel is up
and running it does not get actively revoked and removed. This poses a security
risk as connections keep beeing alive.
Whenever any parameter of a peer changes we actively remove the peer and fully
recreate it on the fly.

T4630: disallow same source-interface for macsec and pseudo-ethernet
|
|
In the OpenVPN site-to-site config we can use IPv6 peers
without IPv4 configurations but "verify()" checks also local and
remote IPv4 addresses that in this case will be empty lists
For example:
set interfaces openvpn vtun2 local-address 2001:db8::1
set interfaces openvpn vtun2 remote-address 2001:db8::2
Check in the commit (v4loAddr == v4remAddr) <= both empty lists
commit
DEBUG: [] == [] or ['2001:db8::2'] == []
So we should also check v4loAddr, v4remAddr, v6loAddr, v6remAddr
are not empty

Fixes several bugs around bonding member interface states not matching
the committed configuration, including:
- Disabled removed interfaces coming back up
- Newly added disabled interfaces not staying down
- Newly added interfaces not showing up in the bond
|
|
Refactor interfaces-bonding.py to simplify existing code and to remove
potentially bugprone sections in preparation for member add/remove
fixes for T4668.
