deployments in cgnat. (#2694)
|
|
VyOS has several services relaying on the PKI CLI tree to retrieve certificates.
Consuming services like ethernet, openvpn or ipsec all re-implemented the same
code to retrieve the certificates from the CLI.
This commit extends the signature of get_config_dict() with a new option with_pki
that defaults to false. If this option is set, the PKI CLI tree will be blended
into the resulting dictionary.

T5880: verify_source_interface() should not allow dynamic interfaces like ppp, l2tp, ipoe or sstpc client interfaces
|
|
A tunnel interface can not properly be sourced from a pppoe0 interface when
such interface is not (yet) connected to the BRAS. It might work on a running
system, but subsequent reboots will fail as the source-interface most likely
does not yet exist.
|
|
This improves commit 3c990f49e ("login: T5875: restore home directory
permissions when re-adding user account") in a way that the home directory
owner is only altered if it differs from the expected owner.
Without this change on every boot we would alter the owner which could increase
the boot time if the home of a user is cluttered.
|
|
We will use _ as CLI level divider. The XML definition filename and also
the Python helper should match the CLI node.
Example:
set interfaces ethernet -> interfaces_ethernet.xml.in
set interfaces bond -> interfaces_bond.xml.in
set service dhcp-server -> service_dhcp-server-xml.in

dhcp: T3316: Adjust kea lease files' location and permissions
|
|
login: T5875: restore home directory permissions when re-adding user account
|
|
Shorten and simplify `system domain-search` config path from:
```
set system domain-search domain <domain1>
```
to:
```
set system domain-search <domain1>
```
This will shorten the path and also make consistent with `domain-search`
config in other places (like `dhcp-server`).
|
|
After deleting a user account and working with a newly added account, we see
that after rebooting in the previously saved configuration, the user is
re-added but it's home directory might have an old UID set on the filesystem.
This is due to the fact that vyos config does not store UIDs. When adding a
user account to the system we now check if the home directory already exists
and adjust the ownership to the new UID.

Remove the word "error" from a Warning only message to not irritate the user.

Move the kea lease file to a separate directory `/config/dhcp` that `kea`
process can write to so that subprocesses spawned by `kea` process can
operate on the lease files.
To allow `kea` process to write to `/config/dhcp`, add `_kea` user to
`vyattacfg` group. And the lease files are owned completely by `_kea`
user to play well with `kea-lfc` process.
Specifically, this is necessary for `kea-lfc` which is spawned by `kea`
process to clean up expired leases. Since `kea-lfc` creates additional
backup lease files, it needs write access to the lease file directory.
Additionally, change the extension of the lease file from `.leases` to
`.csv` to reflect the actual file format.

T5801: Rewritten L2TP to get_config_dict

T5842: Rewritten PPTP to get_config_dict

dhcp: T3316: Support hostname, DUID and MAC address in reservation
|
|
Rewritten PPTP to get_config_dict
Fixed 'dynamic-author' commands. These commands did not create
anything in accel-ppp config.
|

We always enable HTTPS in ddclient configuration, however
`http://checkip.dyndns.org` is HTTP only and does not support HTTPS.
Warn the user if they are using this service.
Also, make `url` in `web-options` mandatory.

configdict: T5837: add support to return added nodes when calling node_changed()
|
|
snmp: 5856: fix service removal error
|
|
When deleting SNMP from CLI the 'delete' key was not honored in the config
dictionary, leading to a false process startup causing the following error:
Job for snmpd.service failed because the control process exited with error code.
See "systemctl status snmpd.service" and "journalctl -xeu snmpd.service" for details.
|
|
node_changed() will return a list of changed keys under "path". We are not
always interested what changed, sometimes we are only interested if something
changed at all, that what vyos.configdict.is_node_changed() is for.

Match mark allows to use firewall marks of packet to use
a specific pool
Example of instance config /run/jool/instance-100.json
```
...
"pool4": [
{
"protocol": "TCP",
"prefix": "192.0.2.10",
"port range": "1-65535",
"mark": 23
},
...
```

After update KEA to 2.4.x in the bf04cd8fea44d375fb7d93d75a1f31c220730c88
there is a file that expects ConditionFileNotEmpty=/etc/kea/kea-api-password
It cause the unit `kea-ctrl-agent.service` cannot start
systemd[1]: kea-ctrl-agent.service - Kea Control Agent was skipped because of an unmet condition check (ConditionFileNotEmpty=/etc/kea/kea-api-password)
Override systemd kea-ctrl-agent.service do not check this file

Reinstate support for hostname in DHCP reservation. Having `hostname` in
allows for server-side assignment of hostname. This is useful for static
lookup of hostname.
Ensure that hostname is a valid FQDN (doesn't have underscore, etc.)
Additionally, support using either of DUID or MAC address for
reservation. While MAC address is typically used for IPv4, and DUID is
typically used for IPv6, either of them can be used in IPv4 and IPv6
reservations in Kea.

srv6: T591: enable SR enabled packet processing on defined interfaces
|
|
T2898: add ndp-proxy service
|
|
VyOS CLI command
set service ndp-proxy interface eth0 prefix 2001:db8::/64 mode 'static'
Will generate the following NDP proxy configuration
$ cat /run/ndppd/ndppd.conf
# autogenerated by service_ndp-proxy.py
# This tells 'ndppd' how often to reload the route file /proc/net/ipv6_route
route-ttl 30000
# This sets up a listener, that will listen for any Neighbor Solicitation
# messages, and respond to them according to a set of rules
proxy eth0 {
# Turn on or off the router flag for Neighbor Advertisements
router no
# Control how long to wait for a Neighbor Advertisment message before invalidating the entry (milliseconds)
timeout 500
# Control how long a valid or invalid entry remains in the cache (milliseconds)
ttl 30000
# This is a rule that the target address is to match against. If no netmask
# is provided, /128 is assumed. You may have several rule sections, and the
# addresses may or may not overlap.
rule 2001:db8::/64 {
static
}
}

The Linux Kernel needs to be told if IPv6 SR enabled packets whether should be
processed or not. This is done using
/proc/sys/net/conf/<iface>/seg6_* variables:
seg6_enabled - BOOL
Accept or drop SR-enabled IPv6 packets on this interface.
Relevant packets are those with SRH present and DA = local.
0 - disabled (default)
not 0 - enabled
Or the VyOS CLI command:
* set protocols segment-routing interface eth0 srv6
|
|
Enable/Disable VRF strict mode, when net.vrf.strict_mode=0 (default) it is
possible to associate multiple VRF devices to the same table. Conversely, when
net.vrf.strict_mode=1 a table can be associated to a single VRF device.
A VRF table can be used by the VyOS CLI only once (ensured by verify()), this
simply adds an additional Kernel safety net, but a requirement for IPv6 segment
routing headers.

frr: T4020: add option to define number of open file descriptors
|
|
This allows the operator to control the number of open file descriptors each
daemon is allowed to start with. The current assumed value on most operating
systems is 1024.
If the operator plans to run bgp with several thousands of peers then this is
where we would modify FRR to allow this to happen.
set system frr descriptors <n>
