veth: T7990: fix stale DHCP clients when removing virtual Ethernet pairs
|
|
show_sessions returns a list of dicts of the internal session record
structure for each live session. As this call is itself mediated by a
session one can specify exclude_self=True, resp., exclude_other=True.
|
|
|
|
pid is the more commonly passed argument, and this maintains consistency
with configsession arg use.
|
|
The standalone script teardown-config-session.py is called on CLI
config-mode exit, to close the persistent vyconf config session. Instead
of injecting the config-mode env var into the external script to
indicate a non-ephemeral session, add keyword 'extant' to find existing
session.

The addition of alert exn to vyos1x-config allows an audit of all raised
exceptions, providing fixes for consistent handling and error reporting.

container: T7305: fix VRF loss when restarting pods
|
|
When removing a veth interface, the kernel automatically deletes its peer
interface, since veth devices always exist in pairs. However, this automatic
removal does not trigger the remove() helper in vyos.ifconfig.interfaces, which
can leave associated DHCP(v6) clients running indefinitely.
For example:
ip link add veth0 type veth peer name veth1
ip link del dev veth1
Removing veth1 will also delete veth0 in the kernel, but the VyOS cleanup
routines are never called for veth0. This patch ensures that peer removal
correctly purges both interfaces and their associated state.
This drops the workarounds in veth smoketest and falls back to the common
interface smoketests from the inherited base class.

T7789: T7661: VPP prevent failing to load XDP in clouds (ena/gve drivers)
|
|
Container networks are only started when there is at least one active consumer.
If a network is created without any attached containers, it does not need to be
assigned to a VRF yet.
When the last container in a pod is stopped, its associated container network
is removed. Upon container restart, the kernel recreates the network, but the
VRF assignment may be lost in the process.
This change ensures that all container networks are correctly reattached to
their designated VRFs when a pod restarts.

T7949: VPP add the ability to configure bond subinterfaces for NAT
|
|
- Fixed issue in T7977
- Added smoketest for 3 or more interfaces in rule
- Added wait_for function to utils/misc.py
|
|
Some cloud NICs (ena, gve) fail to load XDP if all RX queues are configured. To
avoid this, we limit the number of queues to half of the maximum supported by the driver.

* dhcp-server: T3936: Added support for DHCP Option 82
This commit adds support in both the CLI and the underlying code for
DHCP Option 82 to be used to filter/route DHCP address assignments.
The primary use case for this is to support enterprise switches which
can "tag" DHCP requests with physical real world informaiton such as
which switch first saw the request and which port it originated from
(known in this context as remote-id and circuit-id). Once
client-classes have been defined they can be assigned to subnets or
ranges so that only certain addresses get assigned to specific
requests.
There is also a corresponding documentation update which pairs with
this code change.

T3680: protocols: add dhclient hooks for dhcp-interface static routes
|
|
kea: T7925: Improve error handling, validate IPv6 PD prefix length
|
|
Solves the problem that vyos-configs in FRRender caches configuation and
DHCP changes are ignored.
* Add src/helpers/vyos-request-configd-update.py that requests vyos-configd
to update FRR configuration.
* Make dhclient hooks use it instead of calling protocols_static.py
* Make FRRender cache not only configuration but also DHCP gateways so
that is any of them changes, FRR configuration is updated

Execute commands for vpp sflow with API calls. Use values for polling interval and sampling rate from 'system sflow'. Add op-mode command

T7930: VPP: Changing NAT44 settings resets `forwarding_enabled` to False
|
|
Enable/disable NAT forwarding in vpp_nat.py script to prevent it's reset
|
|
While debugging and resolving the underlying VRF assignment issue in T7929,
this code path was refactored for clarity. Previously, the check_dhcp() helper
function relied on the parent scope’s vrf variable. Although this worked
correctly, it was not clean or explicit. The function now takes and uses its
own vrf argument, improving readability and maintainability.
|
|
This update refactors the code path to eliminate unnecessary nesting when
processing interfaces using PPPoE or DHCP that are bound to a VRF.
Previously, the configuration dictionary was only populated if a static route
was defined under the corresponding VRF node. This behavior was incorrect, as
interfaces tied to a VRF can receive dynamic routes - such as a default route
via DHCP - without having any static routing configuration. A typical use case
is a VRF dedicated to out-of-band management.

T7897: VPP: fix rx-mode interrupt for XDP driver with workers
|
|
T7890: VPP fix verify_dev_driver
|
|
The verify_dev_driver must return bool value, but it a device
does not have PCI address (for example veth interface)
it returns Traceback
Fix this

T7750: VPP: CGNAT commit failure with vpptunX interface
|
|
dhcp-server: T7723: add DHCP Option 26 (interface MTU)
|
|
Allow using bond interfaces in CGNAT. Improve interface cleanup to rely
on VPP API queries, as VPP config changes may modify interface indexes
|
|
Change vyos.template.get_dhcp_router to use '*.lease' file instead
of '.leases' file - in 'leases' there can be several last leases
and current one may not be the first one in file. '*.lease' file
contains current lease.
|
|
Remove no-syscall-lock from CLI and enable this option if interrupt/adaptive mode is enabled and workers are configured.
Also forbid interrupt mode for ixgbevf driver
|
|
There is currently no use for us for unique transaction ids emitted by
FRR to syslog.
|
|
There is no need for informational logging which adds quiet some noise to
syslog. Informational logging can be enabled when FRR debug swtitch is
set.
