2023-08-28T5428: fix DHCP address renewal/release when running in VRFChristian Breunig
2023-09-01vrf: 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. (cherry picked from commit 005151f77be5cf999689cfd03620bbc39df59018)
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 (cherry picked from commit 52342f389af2da2995b858d026e6fbcad5c8bfaa)

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.

2021-07-25vrf: T31: ignore iproute2 errorsChristian Poessinger
Re-issuing the same iproute2 commands can lead to errors, simply ignore them and not raise a Python exception. (cherry-picked from commit 9920f7340d60b51d32bad9dbd24a907718f72837)

2020-05-29airbag: T2088: explicit enabling of the featureThomas Mangin
airbag must now be explicitly installed. the patch also allow to fully disables the installation of the logging code at setup (and not just installing and doing nothing)

2020-04-04vrf: T2221: when deleting vrf also delete unreachable routeChristian Poessinger
If the unreachable routes for IPv4 and IPv6 are not deleted, there will be an error when creating the same VRF again after removal. Error changing VRF: Command '['sudo', 'ip', '-4', 'route', 'del', 'vrf', 'Blue', 'unreachable', 'default', 'metric', '4278198272']' returned non-zero exit status 2.

2020-03-29vrf: T31: bugfix after converting remove list to dictChristian Poessinger
The list of VRFs to remove has been converted to a dict. The deletion of a VRF was no longer triggered as the logic still thought it is a list.

2020-03-04vrf: T31: reorder routing table lookupsChristian Poessinger
Linux routing uses rules to find tables - routing targets are then looked up in those tables. If the lookup got a matching route, the process ends. TL;DR; first table with a matching entry wins! You can see your routing table lookup rules using "ip rule", sadly the local lookup is hit before any VRF lookup. Pinging an addresses from the VRF will usually find a hit in the local table, and never reach the VRF routing table - this is usually not what you want. Thus we will re-arrange the tables and move the local lookup furhter down once VRFs are enabled.
2020-03-04vrf: T31: adding unreachable routes to the routing tablesChristian Poessinger
2020-03-04vrf: T31: prior to the v4.8 kernel iif and oif rules are neededChristian Poessinger
.. we run on 4.19 thus this is no longer needed.
2020-03-04vrf: T31: create iproute2 table to name mapping referenceChristian Poessinger
2020-03-04vrf: T31: rename 'vrf disable-bind-to-all ipv4' to 'vrf bind-to-all'Christian Poessinger
By default the scope of the port bindings for unbound sockets is limited to the default VRF. That is, it will not be matched by packets arriving on interfaces enslaved to an l3mdev and processes may bind to the same port if they bind to an l3mdev. TCP & UDP services running in the default VRF context (ie., not bound to any VRF device) can work across all VRF domains by enabling the 'vrf bind-to-all' option.
2020-03-04vrf: T31: support add/remove of interfaces from vrfChristian Poessinger
2020-03-04vrf: T31: remove superfluous vyos.vrf library functionsChristian Poessinger
vyos.vrf.list_vrfs() was only used in one function thus building a library is no longer needed. If it is needed in the future it should be placed into a library again.
2020-03-04vrf: T31: reduce script complexityChristian Poessinger
Keep it simple and stupid :)
2020-03-04vrf: T31: no need to use sudo calls in vrf.pyChristian Poessinger
All configuration mode scripts are already run with sudo.
2020-03-04vrf: T31: initial support for a VRF backend in XML/PythonThomas Mangin
This is a work in progress to complete T31 whoever thought it was less than 1 hour of work was ..... optimistic. Only VRF vreation and show is supported right now. No interface can be bound to any one VRF.
