T5169: Add PoC for generating CGNAT rules rfc6888
|
|
|
|
Add PoC for generating CGNAT rules
https://datatracker.ietf.org/doc/html/rfc6888
Not all requirements are implemented, but some of them.
Implemented:
REQ-2
```
A CGN MUST have a default "IP address pooling" behavior of "Paired"
CGN must use the same external IP
address mapping for all sessions associated with the same internal
IP address, be they TCP, UDP, ICMP, something else, or a mix of
different protocols.
```
REQ-3
```
The CGN function SHOULD NOT have any limitations on the size
or the contiguity of the external address pool
```
REQ-4
```
A CGN MUST support limiting the number of external ports (or,
equivalently, "identifiers" for ICMP) that are assigned per
subscriber
```
CLI:
```
set nat cgnat pool external ext1 external-port-range '1024-65535'
set nat cgnat pool external ext1 per-user-limit port '1000'
set nat cgnat pool external ext1 range 192.0.2.222/32
set nat cgnat pool internal int1 range '100.64.0.0/28'
set nat cgnat rule 10 source pool 'int1'
set nat cgnat rule 10 translation pool 'ext1'
```

Commit b30faa43c (container: T6208: rename "cap-add" CLI node to "capability")
added an AttributeError referencing an out of scope variable.
This has been fixed.

Commit 1b364428f ("login: T5875: restore home directory permissions only when
needed") added logic to chown the users home directory if it's UID changes.
This might happen when a user account is deleted and re-added to the system.
Under rar e circumstances it was possible that the implementation triggered
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 'getpwuid(): uid not found: XXXX'
This has been fixed by re-arranging the code path with an additional try/except
if the PW database information could not be retrieved leading to an implicit
chown() of the home directory to the user beeing added.

Containers have the ability to add Linux system capabilities to them, this is
done using the "set container name <name> cap-add" command.
The CLI node sounds off and rather should be "set container name <name>
capability" instead as we use and pass a capability to a container and not
add/invent new ones.

The problem was introduced in [1] but the config migrator part unfortunately
was added to the wrong version [2]. As IPoE config version 0 was only active
during the 1.3 development cycle and VyOS 1.3.0 was already released with config
version 1 we can safely drop the migrator 0-to-1 and move the code to 1-to-2 to
properly support upgrades from VyOS 1.3 -> 1.4 or newer.

There are cloud environments available where the maximum supported ethernet
MTU is e.g. 1450 bytes, thus we clamp this to the adapters maximum MTU value
or 1500 bytes - whatever is lower.

configverify: T6198: add common helper for PKI certificate validation
|
|
The next evolutional step after adding get_config_dict(..., with_pki=True) is
to add a common verification function for the recurring task of validating SSL
certificate existance in e.g. EAPoL, OpenConnect, SSTP or HTTPS.

T6192: allow binding SSH to multiple VRF instances
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Currently VyOS only supports binding a service to one individual VRF. It might
become handy to have the services (initially it will be VRF, NTP and SNMP) be
bound to multiple VRFs.
Changed VRF from leafNode to multi leafNode with defaultValue: default - which
is the name of the default VRF.

system: T6193: invalid warning "is not a DHCP interface but uses DHCP name-server option"

T6178: Check that certificate exists during reverse-proxy commit

|
name-server option"
This fixes an invalid warning when using a DHCP VLAN interface to retrieve the
system nameserver to be used. VLAN CLI config is not properly expanded
leading to a false warning:
[ system name-server eth1.10 ]
WARNING: "eth1.10" is not a DHCP interface but uses DHCP name-server option!

This changes behaviour from fetching CA chain in PKI, to the user manually setting CA certificates.
Prevents unwanted parent CAs existing in PKI from being auto-included as may not be desired/intended.
