2021-09-03login: T971 allow quoting in public-keys optionsPaul Lettington
This patch allows the use of `"` in ssh public-key options which unlocks the ability to set the `from` option in a way that sshd will accept to limit what hosts a user can connect from.

2021-09-02login: T3792: bugfix for usernames containing a hyphenChristian Poessinger
While migrating to get_config_dict() in commit e8a1c291b1 ("login: radius: T3192: migrate to get_config_dict()") the user-name was not excluded from mangling (no_tag_node_value_mangle=True). This resulted in a username "vyos-user" from CLI to be actually created as "vyos_user" on the system. This commit also adds respective Smoketests to prevent this in the future.
2021-09-02login: radius: T3192: drop workaround required by get_config_dict()Christian Poessinger
The workaround is no longer required, as the issue was resolved in get_config_dict() so if it is a <multi/> node, a list is always returned.
2021-09-02op-mode: T1376: speed up tab-completion for DHCP pool listingChristian Poessinger
Commit 9f20bee81c ("T1376: improve show_dhcp and show_dhcpv6") added the tab completion helper to list the availbale IP pools to query. This was done by calling a python script which then called cli-shell-api which resulted in a penalty by the Python interpreter startup. This can be solved by directly using the cli-shell-api wrapper available as <path> in op-mode - as also seen for DHCPv6.

2021-08-31vyos.ethtool: T3163: purify code to read and change flow-control settingsChristian Poessinger
It makes no sense to have a parser for the ethtool values in ethtool.py and ethernet.py - one instance ios more then enough!
2021-08-31ethernet: T3163: only change ring-buffer settings if requiredChristian Poessinger
Only update the RX/TX ring-buffer settings if they are different from the ones currently programmed to the hardware. There is no need to write the same value to the hardware again - this could cause traffic disruption on some NICs.
2021-08-31ethernet: T2241: check if interface supports changing speed/duplex settingsChristian Poessinger
Not all interface drivers have the ability to change the speed and duplex settings. Known drivers with this limitation are vmxnet3, virtio_net and xen_netfront. If this driver is detected, an error will be presented to the user.
2021-08-31ssh: T3789: add custom validator for base64 encoded CLI dataChristian Poessinger
SSH keys used for remote login are supplied as base64 encoded data on the CLI. The key is not validated, thus an invalid copy/pasted key will render the login useless. This commit adds a custom and re-usable validator which check if the data is properly base64 encoded.
2021-08-31ethernet: T3514: bail out early on invalid adapter speed/duplex settingChristian Poessinger
Ethernet adapters have a discrete set of available speed and duplex settings. Instead of passing every value down to ethtool and let it decide, we can do this early in the VyOS verify() function for ethernet interfaces.

2021-08-30ethernet: T3619: fix VyOS 1.2 -> 1.3 performance degradationChristian Poessinger
An analysis of the code base from VyOS 1.2 -> 1.3 -> 1.4 revealed the following "root-cause" VyOS 1.2 uses the "old" node.def file format for: * Generic Segmentation Offloading * Generic Receive Offloading So if any of the above settings is available on the configuration CLI, the node.def file will be executed - this is how it works. By default, this CLI option is not enabled in VyOS 1.2 - but the Linux Kernel enables offloading "under the hood" by default for GRO, GSO... which will boost the performance for users magically. With the rewrite in VyOS 1.3 of all the interface related code T1579, and especially T1637 this was moved to a new approach. There is now only one handler script which is called whenever a user changes something under the interfaces ethernet tree. The Full CLI configuration is assembled by get_interface_dict() - a wrapper for get_config_dict() which abstracts and works for all of our interface types - single source design. The problem now comes into play when the gathered configuration is actually written to the hardware, as there is no GSO, GRO or foo-offloading setting defined - we behave as instructed and disable the offloading. So the real bug originates from VyOS 1.2 and the old Vyatta codebase, but the recent XML Python rewrites brought that one up to light. Solution: A configuration migration script will be provided starting with VyOS 1.3 which will read in the CLI configuration of the ethernet interfaces and if not enabled, will query the adapter if offloading is supported at all, and if so, will enable the CLI nodes. One might say that this will "blow" the CLI configuration but it only represents the truth - which was masked in VyOS 1.2. (cherry picked from commit a515212f4efb08846df04405f31a828edcd63552)
2021-08-30ethernet: T3619: rename interfaces migration scriptsChristian Poessinger
VyOS 1.4 already had a migrator for interfaces 20 -> 21, but this is a different one compared to the one in VyOS 1.3 - thus we bump every migration scripts version by one to have the same 20-to-21 converter in both VyOS 1.3 and 1.4. This is possible as VyOS 1.4 (sagitta) is still a highly experimental version and expected to break from time to time :(.

Check a port availability only if it was changed in current commit. This should protect from fail-positive errors when other parameters change for an interface.

2021-08-26wireguard: T3763: Added check for listening port availabilityzsdc
Each wireguard interface requires a unique port for in and out connections. This commit adds the new `vyos.util` function - `check_port_availability`, and uses it to be sure that a port that is planned to be used for wireguard interface is truly available and not used by any other services (not only other wireguard interfaces).

2021-08-24bgp: T3759: "l2vpn evpn" and ipv4/ipv6 safi route-targets differChristian Poessinger
The "l2vpn evpn" address-family route-target command only accepts a single route-target value consisting of (A.B.C.D:MN|EF:OPQR|GHJK:MN). The "ipv4-unicast or ipv6-unicast" address-family route-target command for VPNs support multiple, whitespace separated route-target values. This commit adds a new custom validator named "bgp-route-target" with a --single and a --multi option to pass one or more route-target values.

2021-08-24container: T3769: disable bridge "hairpinMode" modeChristian Poessinger
After commit 209ce3d9 ("container: T3769: when container networks are used, always bridge the networks") IP masquerading (NAT) was disabled. No need to keep the haipin flag.
2021-08-23container: T3769: when container networks are used, always bridge the networksChristian Poessinger
As VyOS is a network operation system with bridging and NATing available from the VyOS CLI, it makes no sense to let podman do it's own sort of "NAT". If one really want's to NAT into a container, use the VyOS CLI to do so. If you wan't to bridge your networks, use the VyOS CLI to do so.

2021-08-23container: T2216: no need to query container statusChristian Poessinger
As VyOS CLI is the only truth for dealing with containers we do not need to query if a container is running, exists or what so ever. We simply always restart it if something changes and do not rely on the underlaying Linux status. If a users does container stuff under the hood - it will be overridden.

2021-08-21pppoe: T3090: migrate to vyos.ifconfig library to use the full potentialChristian Poessinger
Now that MSS clamping is done on the "per-interface" level the entire PPPoE stuff would have needed to get a full copy in GNU BASH for this or, participate in the common library. Add a new PPP ip-up script named 99-vyos-pppoe-callback which will call the vyos.ifconfig.PPPoEIf.update() function to configure everything as done with all other interfaces. This removes duplicated code for VRF assignment and route installation when a PPPoE interface is brought up or down.
