2021-09-26vyos.ifconfig: T3860: bugfix in get_mac_synthetic()Christian Poessinger
Commit 081e23996f (vyos.ifconfig: get_mac_synthetic() must generate a stable "MAC") calculated a "stable" synthetic MAC address per the interface based on UUID and the interface name. The problem is that this calculation is too stable when run on multiple instances of VyOS on different hosts/hypervisors. Having R1 and R2 setup a connection both via "tun10" interface will become the same "synthetic" MAC address manifesting in the same link-local IPv6 address. This e.g. breaks OSPFv3 badly as both neighbors communicate using the same link-local address. As workaround one can: set interfaces tunnel tun1337 address 'fe80::1:1337/64' set interfaces tunnel tun1337 ipv6 address no-default-link-local This commit changes the way in how the synthetic MAC address is generated. It's based on the first 48 bits of a sha256 sum build from a CPU ID retrieved via DMI, the MAC address of eth0 and the interface name as used before. This should add enough entropy to get a stable pseudo MAC address.

2021-09-25vyos.ifconfig: dhcp: T3300: always re-start dhcp client instead of startChristian Poessinger
Commit dd2eb5e5686655 ("dhcp: T3300: add DHCP default route distance") changed the logic on how the DHCP process is going to be started. The systemd unit was always "started" even if it was already running. It should rather be re-started to track changes in e.g. the DHCP hostname setting.

2021-09-20vyos.ifconfig: get_mac_synthetic() must generate a stable "MAC"Christian Poessinger
Commit b7d30137b1 ("vyos.ifconfig: provide generic get_mac_synthetic() method") provided a common helper to generate MAC addresses used by EUI64 addresses for interfaces not having a layer2 interface (WireGuard or ip tunnel). The problem is that every call to the helper always yielded a new MAC address. This becomes problematic when IPv6 link-local addresses are generated and modified on the interface as multiple link-local (fe80::/64) addresses can easily be added to the interface leaving ... a mess. This commit changes the way how the "synthetic" MAC is generated, we generate a UUID which is stable as it is based on the interface name. We take out the last 48 bits of the UUID and form the "MAC" address.
2021-09-20vyos.ifconfig: T2738: can only read from a file when it existsChristian Poessinger
When IPv6 is disbaled on an interface also the sysfs files related to IPv6 for this interface vanish. We need to check if the file exists before we read it.
2021-09-19vyos.ifconfig: T2738: do not remove OS assigned IP addresses from interfaceChristian Poessinger
When using VRRP on any given interface and performing an action against that interface - be it even only changing the alias - will trigger a removal of the VRRP IP address. The issue is caused by: # determine IP addresses which are assigned to the interface and build a # list of addresses which are no longer in the dict so they can be removed cur_addr = self.get_addr() for addr in list_diff(cur_addr, new_addr): When the script calls into the library - we will drop all IP addresses set on the adapter but not available in the config dict. We should only remove the IP addresses marked by the CLI to be deleted!

2021-09-18ipsec: vti: T3831: avoid usinf xfrm if_id 0 - implement shift by oneChristian Poessinger
The key defaults to 0 and will match any policies which similarly do not have a lookup key configuration. This means that a vti0 named interface will pull in all traffic and others will stop working. Thus we simply shift the key by one to also support a vti0 interface.

2021-09-10ethernet: T3802: not all NICs support reading speed/duplex settings in all ↵Christian Poessinger
states Turns out an AX88179 USB 3.0 NIC does not support reading back the speed and duplex settings in every operating state. While the NIC is beeing initialized, reading the speed setting will return: $ cat /sys/class/net/eth6/speed cat: /sys/class/net/eth6/speed: Invalid argument Thus if this happens, we simply tell the system that the current NIC speed matches the requested speed and nothing is changed at this point in time. (cherry picked from commit e2b7e1766cc22c5cd718a5001be6336bdca92eec)

2021-08-31vyos.ethtool: T3163: ring-buffer values should be stored as stringChristian Poessinger
Commit 29082959 ("ethernet: T3163: only change ring-buffer settings if required") added a delta-check code for the ring buffer values, unfortunately this was never properly evaluated as str() and int() got compared resulting always in an unequal result.
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.

2021-08-28vyos.ifconfig: T3619: only set offloading options if supported by NICChristian Poessinger
In the past we always told ethtool to change the offloading settings, even if this was not supported by the underlaying driver. This commit will only change the offloading options if they differ from the current state of the NIC and only if it's supported by the NIC. If the NIC does not support setting the offloading options, a message will be displayed for the user: vyos@vyos# set interfaces ethernet eth2 offload gro vyos@vyos# commit [ interfaces ethernet eth2 ] Adapter does not support changing large-receive-offload settings!

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).
