Move sshd_config file to /run so it must be generated on every boot and is
not stored accidently.

The problem exists when LLDP is not configured but one wants to run the detail
command. Running "show lldp neighbors" is not possible when LLDP is not running.
This case is already handled for "show lldp neighbors" and has been extended
for "show lldp neighbors detail".

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.

Make the port used for RADIUS accounting user configurable. This is now
valid for the following services which are based on Accel-PPP:
* ipoe-server
* pppoe-server
* l2tp
* pptp
* sstp

Migration files on the storage should be done one time by a migration script
instead of every time the configuration changes. Moving this to an older
migration script is fine as this is around for a long time and all rolling
releases are already up2date. It only affects updates from VyOS 1.2 series.

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.

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.

This can be used to see if a tagNode has been changed. It will return a list
of changed nodes.

After switching from raw parsing of the interface options to get_config_dict()
this utilizes another utility function which wraps get_config_dict() and adds
other common and reused parameters (like deleted or bridge member).
Overall this drops redundant code (again) and makes the rest more maintainable
as we only utilize a single function.

While providing a new update() method in vyos.ifconfig.interfaces() this is

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!

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.

Since it's relatively rarely used, Python's startup time should't
be much of a problem.

The only calls to config (return_value, return_values, exists) do not
throw VyOSError; remove unneeded except.

Fix for https://phabricator.vyos.net/T2725
T2492 / a07e22377ab83104ac925e13d1824f241f0f8d4a
introduced a change which broke the initialization of
the user dict. In case the config contained an user
without an encrypted-password set, the property would
be missing and the commit would crash with
`KeyError: 'password_encrypted'`

The calculated size of DHCP server address pools was not corrent. The
fact that both boundaries of address ranges are inclusive wasn't
accounted for, so the calculated size was too small by 1 address
per range.

nat: T2709: remove 'translation address' mandatory check
|
|
Rules without a translation address are also valid, they'll modify just
the port and leave the address intact.
This also used to be a valid syntax and it caused an error on upgrade.
|
|
Improve readability of the port validation. Also fixes T2708.
|
|
Add additional verify() stage to check that the relaying interface actually
exists on the system.
|
|
Since it is not impossible to change MACVLAN interface mode on the fly, this fix adds a new one trigger to recreate it from scratch if the mode changed in system config
|
|
|
|
If flow records contain entries with skipped details, this does not allow preparing it for the output table. This fix use safe .get() function to return empty values instead crashing.
Also, added several small formatting fixes.
|
|
Please note that either interface or address can be configured.
system {
options {
http-client {
source-interface eth0
source-address 1.1.1.1
}
}

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.

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.

When migrating the conf from VyOS 1.2 to 1.3 a configuration error could appear
if the user specified "info" as loglevel instead of "INFO". There was no input
validation done in 1.2 but this is now enforced in 1.3.
In VyOS 1.3 loglevel will be always lowercase on the CLI and when migrating the
config this is transformed. Also VyOS 1.2 accpeted any arbitrary loglevel. If
an invalid loglevel is found it will be set to info.

Linux tries to bind sshd to the VRF but it is yet not ready - for any arbitrary
reason. After restarting SSH to often (rate-limiting) it is blocked by systemd.
Using Restart/RestartSec is not enough - systemd services use start rate
limiting (enabled by default). If service is started more than StartLimitBurst
times in StartLimitIntervalSec seconds is it not permitted to start any more.
Parameters are inherited from DefaultStartLimitIntervalSec (default 10s) and
DefaultStartLimitBurst (default 5).
