2024-01-30vrf: 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! (cherry picked from commit a009143a62caca207fdffffcf0b490c747a87025)
2024-01-30vrf: 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. (cherry picked from commit 89f0d347bfe5e468355817a617dc71823a58c284)
2024-01-30vrf: 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 (cherry picked from commit a821b8c603999665ce8a77acb0e44a743811992a)
2023-12-21vrf: 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. (cherry picked from commit 10701108fecb36f7be7eb7ef5f1e54e63da5fb4e)
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.
2023-08-23vrf: T5428: move helpers to common vyos.utils.network moduleChristian Breunig
Helper functions can and will be re-use din different code places.

2023-04-13T5150: initial VRF support for Kernel/Zebra route-map filteringChristian Breunig
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).
2021-08-06frr: T2175: remove no longer required loop when removing VRF VNIChristian Poessinger
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.

Re-issuing the same iproute2 commands can lead to errors, simply ignore them and not raise a Python exception.
