2024-05-01vrf: T6189: render FRR L3VNI configuration when creating VRF instanceChristian Breunig
When adding and removing VRF instances on the fly it was noticed that the vni statement under the VRF instance in FRR vanishes. This was caused by a race condition which was previously designed to fix another bug. The wierd design of a Python helper below the VRF tree to only generate the VNI configuration nodes is now gone and all is rendered in the proper place.
2024-04-18T6221: Return default ip rule values after deleting VRFViacheslav Hletenko
Fix for restoring default ip rule values after deleting VRF Defult values: ``` $ ip rule 0: from all lookup local 32766: from all lookup main 32767: from all lookup default ``` After adding and deleting a VRF we get unexpected values: ``` $ ip rule 1000: from all lookup [l3mdev-table] 2000: from all lookup [l3mdev-table] unreachable 32765: from all lookup local 32766: from all lookup main 32767: from all lookup default ```

Always enable VRF strict_mode
2024-01-22vrf: T5973: fix has_rule() to check for l3mdev ruleChristian Breunig
A code path was missing to check if only priority is available in the result of "ip --json -4 rule show", in the case of l3mdev it's a dedicated key!
2024-01-22vrf: T5973: move initial conntrack firewall table to startupChristian Breunig
There is no need to add and remove this table during runtime - it can lurk in the standard firewall init code.
2024-01-22vrf: T5973: ensure Kernel module is loadedChristian Breunig
This prevents the following error when configuring the first VRF: sysctl: cannot stat /proc/sys/net/vrf/strict_mode: No such file or directory
2023-12-20vrf: T591: define sysctl setting for net.vrf.strict_modeChristian Breunig
Enable/Disable VRF strict mode, when net.vrf.strict_mode=0 (default) it is possible to associate multiple VRF devices to the same table. Conversely, when net.vrf.strict_mode=1 a table can be associated to a single VRF device. A VRF table can be used by the VyOS CLI only once (ensured by verify()), this simply adds an additional Kernel safety net, but a requirement for IPv6 segment routing headers.
2023-08-23vrf: T5428: stop DHCP processes on VRf removalChristian Breunig
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.

2023-01-06static: T4883: fix KeyError: 'table'Christian Poessinger
Commit dafb0da2 ("static: T4883: add a description field for routing tables") added an iproute2 description table but lacked checking if the key exists. This has been fixed and also converted to Jinja2 to keep the "common" style inside the routing protocols. It might feel overengineered indeed.
2022-07-12vrf: T4527: Prevent to create VRF with reserved namesViacheslav Hletenko
VRF names: "add, all, broadcast, default, delete, dev, get, inet, mtu, link, type, vrf" are reserved and cannot be used for vrf name

2022-02-13vrf: T4191: bugfix for "ip rule" when VRFs are createdChristian Poessinger
We always mangled and worked on the "ip rule" singleton even when nothing needed to be changed. This resulted in a VRF hickup when the same VRF was added and removed multiple times. set interfaces ethernet eth1 vrf foo set vrf name foo table '1000' commit delete interfaces ethernet eth1 vrf delete vrf commit set interfaces ethernet eth1 vrf foo set vrf name foo table '1000' commit broke reachability on eth1 - a reboot was required. This change will now only alter the ip rule tables once when VRF instances are created for the first time and will not touch the Kernel "ip rule" representation afterwards.

2021-08-13vrf: T3734: T3728: vni must be configured with a higher priority then bgpdChristian Poessinger
When removing bgp (vrf) instances the assigned VRF vni must be deleted from FRR prior the removal of the bgp settings (T3734). This is now done by moving the CLI command "set vrf name red vni 1000" to a dedicated Python script with a priority higher then bgp.
2021-08-06frr: T3694: temporary disable VRF VNI assignmentChristian Poessinger
Somehow we hit a priority inversion here as we need to remove the VRF assigned VNI before we can remove a BGP bound VRF instance. Maybe move this to an individual helper script that set's up the VNI for the given VRF after any routing protocol (in our case this was triggered by running "make testc" when building an ISO image by the bgp-rpki config).

This is a completing commit to a55585a833 ("frr: T2175: remove no longer required loop when removing routing protocols") that was missed out previously.
2021-07-19vrf: T3655: fix potential error when removing VRF connection tracking tableChristian Poessinger
This extends commit 22791e26 ("VRF: T3655: proper connection tracking for VRFs") so that when the netfilter table is removed, we first check if it exists at all, and if it does not exist we do not remove it. This fixes the smoketest error: PermissionError: [Errno 1] failed to run command: nft delete table inet vrf_zones
2021-07-17VRF: T3655: proper connection tracking for VRFszsdc
Currently, all VRFs share the same connection tracking table, which can lead to problems: - traffic leaks to a wrong VRF - improper NAT rules handling when multiple VRFs contain the same IP networks - stateful firewall rules issues The commit implements connection tracking zones support. Each VRF utilizes its own zone, so connections will never mix up. It also adds some restrictions to VRF names and assigned table numbers, because of nftables and conntrack requirements: - VRF name should always start from a letter (interfaces that start from numbers are not supported in nftables rules) - table number must be in the 100-65535 range because conntrack supports only 65535 zones

2021-04-07vrf: T3344: re-add virtual network identifierChristian Poessinger
Commit 548d9057e3e (vrf: T3344: move dynamic routing protocols under "vrf name <name> protocols") temporary removed the possibility to specify the VNI for a given VRF to to changing of the CLI configuration nodes. As VNI is set inside zebra, we can re-use the now widely deployed frr python library to configure and change the configuration without any interference to other FRR daemons.
