Using 'xdp' will automatically decide if the driver supports 'xdpdrv' or only
'xdpgeneric'. A user later sees which driver is actually in use by calling
'ip a' or 'show interfaces ethernet'.
|
|
The CLI command 'set interfaces ethernet <interface> offload-options xdp" enables
the XDP generic mode on the given interface.

Description: fooa
XDP code is thankfully copied from [1], thank you for this nice tutorial.
NOTE: this is an experimental feature which might break your
forwarding/filtering.

This is the second attempt after commit d247736f ("vyos.ifconfig: T1579: do not
remove IPv6 link-local address on reconfiguration"). We only clean out link-local
IPv6 addresses left over after an interface MAC change.

This reverts commit d247736f67cc056062b75a4215a031bebcfee2ee.
We need to clean link-local IPv6 addresses on link reconfiguration to also drop
no longer existing link-local addresse son MAC address change.

Running ISC DHCP server as backend server for multiple pools served to relay
agents requires DHCPd to explicitly listen on give interfaces or a "transit"
subnet declaration facing the network where we receive the DHCPREQ messages on.
This implements a new "listen-address" CLI node, the given address is validated
if it is assigned to the system and upon success, a proper "subnet { }" statement
is added into dhcpd.conf

interface: T3089: Migrate port mirroring to vyos-1x

using multiline regexes are quite hard to "read" and are really
easy to mess up, this commit adds a new more pythonic
implementation of the library that do not need any multiline regexes.

Commit 6962bc53 ("vyos.template: provide general is_ip(v4|v6) helpers")
introduced new Jinja2 template filters, but the one for checking an address
if it is an IPv6 address was broken as it was yet unused.

While migration to get_config_dict() was introduced in commit 789775af9f5 the
logic for adding an IPv4 or IPv6 peer address was using the wrong dictionary
to determine if it's an IPv4 or IPv6 address.
We now use the proper peer dict over the wrong config dict.
|
|
link-local addresses can still be disabled using:
set interfaces wireguard wg0 ipv6 address no-default-link-local
|
|
|
|
|
|
|
|
|
|
The MAC address is changed after we have set an IP address on the interface or
started dhclient. This will cause some users to receive the wrong IP address
on device startup.
Change to order of how parameters are set in the system. The interface MAC
address is now configured first.

In the implementation of T3042, it will cause two problems:
1. Even if VLAN awareness is not enabled, the VLAN settings of the
vlan filter will be modified. When the bridge member has a WLAN interface,
the error is exposed, so repair it here. You should not modify the
related settings when the VLAN awareness mode is not enabled
2. Even if VLAN awareness is not enabled, the VLAN settings of the
vlan filter will be modified. When the bridge member has a WLAN interface,
due to special settings, the bridge mode cannot be entered and the settings
cannot be completed directly. Therefore, the WLAN interface should be rejected
Enter the bridge with VLAN awareness

This reverts commit 806f35b5856c3f8dae634718a6a9e82cc90bb63a.
Unfortunately this did not work our in the attempt to bridge a station to a
bridge "brX" interface. Also adjusting the wireless interface during operation
cause several exceptions and the feature is removed again as it was never in any
production system.

bridge: T3042: Better fix implementation errors
|
|
In #601, I provided a basic patch. Under this patch, I rely on vif to
detect the vlan id range that the bridge should flow through,
which may lead to greater redundancy in the configuration,
so I am considering detecting effective vlan filters In setting the range
of vlan id that is required to flow through the bridge,
I use set() to complete the deduplication of this vlan id
and set it to the bridge uniformly (at the same time,
I slightly modified the smoke test script)
