2020-08-13ifconfig: dhcp: fix ModuleNotFoundError: No module named 'vyos.ifconfig.dhcp'Christian Poessinger
Commit 21bc98f1 ("ifconfig: dhcp: T2767: client must not start when interface is disabled") dropped the vyos.ifconfig.dhcp module but not removed it from the modules import list.
2020-08-12ifconfig: dhcp: T2767: client must not start when interface is disabledChristian Poessinger
ISC DHCP client will always place an Interface in admin-up state once it is started. We must ensure that if an interface is placed in A/D state that the DHCP client proccess is not launched and terminated if it is running.
2020-08-08http api: T1431: update args of call to install-imageJohn Estabrook
commit 3f8884587 added an endpoint for image management; T2753 updated the command line options. Make script call consistent.
2020-08-04dhcpv6-pd: T2741: support delegation on non existing interfacesChristian Poessinger
We must ignore any return code when invoking dhcpc6 initially. This is required to enable DHCPv6-PD for interfaces which are yet not up and running and my be started later by VyOS.
2020-08-03ifconfig: T2653: unify DHCPv4 configurationChristian Poessinger
Pass the interface dictionary transparently to the DHCP module and render the DHCP client config template directly from the same source instead of transcoding it once more.
2020-08-03ifconfig: T2740: pass config dict to DHCP class for IPv6Christian Poessinger
This removes additional code paths as we can instatly work with the input dict the same was as it was done for PPPoE. This fixes the entire DHCPv6-PD support on non PPPoE interfaces as this was lost in translation while processing T2653.
2020-08-01ifconfig: T2752: fix string format in verify_interface_exists()Christian Poessinger
We do not have a formatted string here thus the "f" keyword is wrong and triggered an exception.
2020-07-31ifconfig: T2653: bugfix on wrong flush_addr APIChristian Poessinger
Commit 29dd5079 ("ifconfig: T2653: remove duplicated code for address flush") used the class method for address flushing, but it was cvalled in the wrong way.
2020-07-30ifconfig: T2746: bugfix for non programmed link-local addressesChristian Poessinger
After the fresh rewrite of the interfaces to a unified solution (T2653) IPv6 link-local addresses are no longer added. This will result in e.g. broken RAs.

2020-07-26wireguard: ifconfig: T2653: move to get_config_dict()Christian Poessinger
The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge.

2020-07-25ifconfig: T2653: make ifname an optional argument to get_interface_dict()Christian Poessinger
Further reduce the boiler-plate code to determine interface tag node or not. It can be passed into get_interface_dict() if explicitly required - else it is taken from the environment.
2020-07-25vyos.configdict: T2653: remove obsolete code from configdict and ifconfig_vlanChristian Poessinger
After all interfaces have been moved to the targetted implementation of T2653 the old implementations of migrating a CLI session to a configuration dict can be dropped.
2020-07-25ifconfig: T2653: move get_ethertype() from configdict to interfaceChristian Poessinger
... as it is only used inside the interface class.
2020-07-25vlan: ifconfig: T2653: move get_removed_vlans() to vyos.configdiffChristian Poessinger
As we wrap up additional functions from this library it should be part of it.

2020-07-25ifconfig: T2653: move vlan configuration code to base classChristian Poessinger
This is required as other interfaces (e.g. pseudo-ethernet or bond) will have VLANs, too.
2020-07-25vyos.configdict: T2653: use dict_merge() over update()Christian Poessinger
With dict.update() existing keys will get overwritten when blending in interface default values.
2020-07-25ifconfig: T2653: implement update() in derived classes for admin up/downChristian Poessinger
Every derived class must implement update() to set the interfaces admin up/down state. This is required to prevend extensive link flaps when e.g. reconfiguring bond interfaces.
2020-07-25vyos.configdict: T2653: add new reusable helper node_changed()Christian Poessinger
This can be used to see if a tagNode has been changed. It will return a list of changed nodes.
2020-07-25ifconfig: T2653: move bridge member check to base classChristian Poessinger
This test is reused by a lot of instances and thus must be moved to the base class.
2020-07-25bridge: ifconfig: T2653: move to get_config_dict()Christian Poessinger
The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge. While providing a new update() method in vyos.ifconfig.interfaces() this is extended for bridge interfaces in the derived bridge class. Signed-off-by: Christian Poessinger <christian@poessinger.com>
2020-07-25vlan: ifconfig: T2653: only enable interface when lower interface is upChristian Poessinger
A VLAN interface can only be placed in admin up state when the lower interface is up, too. If this is not the case the operating system will throw and exception.
2020-07-25ethernet: ifconfig: T2653: move to get_config_dict()Christian Poessinger
The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge. While providing a new update() method in vyos.ifconfig.interfaces() this is extended for ethernet based interfaces which also supports 802.1q, 802.1ad VLANs. This commit migrates the existing codebase for an ethernet based interfaces and implements the missing parts for VLANs. Adding or migrating other interfaces (e.g. bridge or bond) will become much easier as they must reuse the entire functionality - we now walk towards a single codepath. Thanks for all who made this combined effort possible! Signed-off-by: Christian Poessinger <christian@poessinger.com>
2020-07-25vyos.util: add common helper to load kernel modulesChristian Poessinger
l2tpv3, wireguard, wirelessmodem, nat all require additional Kernel modules to be present on the system. Each and every interface implemented their own way of loading a module - by copying code. Use a generic function, vyos.util.check_kmod() to load any arbitrary kernel module passed as string or list.

2020-07-21 vyos.template: T2720: Rework vyos.template Python libraryRobert Schindler
Apart from code cleanup, this allows any module that wants to render a template to register custom jinja2 template filters by using the new @register_filter decorator. Examples can be found in vyos.template itself. Using the new render_to_string function, the rendered template can also be returned as a string instead of being written to a file.
2020-07-21vyos.util: T2720: Add file descriptor support to chmod and chownRobert Schindler
Extended the chmod() and chown() functions in vyos.util to also operate on open file descriptors in addition to paths. This allows code that creates files to quickly change mode and owner even before anything has actually been written to the file.
2020-07-19interface: T2519: add broadcast address when adding IPv4 addressesJernej Jakob
This adds the last IP of the subnet being added as the broadcast address. Example: adding 192.0.2.1/24 would yield: inet 192.0.2.1/24 brd 192.0.2.255 scope global dum0 Without this the broadcast address would be missing. Addidionally join two is_ipv4 calls into one.
2020-07-18configdiff: T2689: add configdiff classJohn Estabrook
The configdiff class provides: (1) An abstract representation of VyOS config state, for use in configuration mode scripts. (2) Methods to query the differences between the effective and session config.
2020-07-18vyos.ifconfig: T2673: Fix admin state if the mac address is changed for an ↵srividya0208
interface Changes are made in the interface.py script in order to bring the admin state to 'UP' after the mac is manually added in system config.The script is marking the interface from up to down state(as the MAC address can only be changed if interface is in 'down' state) but it is not bringing it up after the change

This is a minor modification of the implementation by Thomas Mangin.

2020-07-12snmp: T2687: replace 3rd party hash library with custom codeChristian Poessinger
The 3rd party library used for calculating the SNMP hashes in advance only worked for SHA and nod for MD5 as SHA was hardcoded [1]. The code has been replaced by a class-less implementation providing only the required functionality. [1]: https://github.com/TheMysteriousX/SNMPv3-Hash-Generator/issues/2
2020-07-12vyos.snmpv3_hashgen: add license textChristian Poessinger
2020-07-11snmp: T2687: precalculate snmpv3 encrypted keysChristian Poessinger
As of now when adding new credentials for any SNMPv3 user we submit the credential either plaintext or encrypted. A plaintext credential will be hashed by SNMPd in the background and then passed back into the CLI so it's not stored in cleartext. This feels like the wrong way in changing the CLI content with data produced by a 3rd party daemon which implements the service. It feels like the tail wiggles the entire dog. This should be changed in the following way: - After retrieving the plaintext password from CLI, use Python to hash the key in advance - Re-populate the encrypted key into the CLI and drop the plaintext one - Generate service configuration and continue startup of SNMPd This also fixes a race condition when SNMPd started up but not properly provided the hasehd keys in the configuration resulting in a ConfigurationError. Now as we also support binding SNMPd to a VRF this fixes a deadlock situation on bootup as we can only bind late to the VRF and require up to 5 restarts of the service - but the service will never start.

2020-07-03vyos.template: T2676: add custom Jinja2 filter for IP handlingChristian Poessinger
NTP configuration file requires the IP address and a netmask for client subnets but the CLI will only provide a prefix based ntoation. Use custom, reusable JInja2 template to transform a CIDR based prefix into its address and netmask portion for IPv4 and IPv6. Jinja2 custom filters are regular python functions - thus they can be re-used directly when e.g. verifying the configuration in vyos-smoketests.
