The subnet router anycast address is predefined. Its format is as follows:
| n bits | 128-n bits |
+------------------------------------------------+----------------+
| subnet prefix | 00000000000000 |
+------------------------------------------------+----------------+
The "subnet prefix" in an anycast address is the prefix that identifies a
specific link. This anycast address is syntactically the same as a unicast
address for an interface on the link with the interface identifier set to zero.
Packets sent to the Subnet-Router anycast address will be delivered to one
router on the subnet. All routers are required to support the Subnet-Router
anycast addresses for the subnets to which they have interfaces.
The Subnet-Router anycast address is intended to be used for applications where
a node needs to communicate with any one of the set of routers.
Our code as of now returns the subnet router anycast address as the
first_host_address().

Rename chain level defaults log option from `enable-default-log` to
`default-log` for consistency.

T5775: firewall: re-add state-policy to firewall. These commands are …
|
|
Remove what was not working on 1.3, migrate what was working to new syntax and extend feature for ipv6.
|
|
included in <set firewall global-options state-policy> node.
|
|
to be able to catch logs using separte rule for default-action
|
|
enables log capabilities for default-action in base chains. And of course, add option for enabling log for default-action
|
|
- Moves MSS node out of `tcp-flags.xml.i` and into `tcp-mss.xml.i`
- Update smoketest to verify TCP flag matching
|
|
Interface 'any' not expected in nft rules, it means that option
iifname shouldn't exist at all
set system conntrack ignore ipv4 rule 10 inbound-interface 'any'
table ip raw {
chain VYOS_CT_IGNORE {
iifname "any" counter packets 0 bytes 0 notrack comment "ignore-10"
return
}
}
Fix it
|
|
add IPv6 support and firewall groups
|
|
accidentaly removed. Update smokestest: remove zone test and fix test_sysfs test
|
|
scripts and src firewall
|
|
Multiple scripts use the same hardcoded path for DHCP client leases in
different direcotries - this can't be worse.

Values of the list for the 'range_to_regex' could be not only range
values as ['10-20', '22-30'] but also and not range values like
['10-20', '30', '80']
Fix if we args is list and non range values are exists in ths list
% range_to_regex(['10-20', '80'])
'(1\\d|20|80)'
|
|
Extend template filter 'range_to_regex'
Allow list of ranges as argument
% range_to_regex(['11-12', '14-15'])
'(1[1-2]|1[4-5])'

T4916: Rewrite IPsec peer authentication and psk migration
|
|
Rewrite strongswan IPsec authentication to reflect structure
from swanctl.conf
The most important change is that more than one local/remote ID in the
same auth entry should be allowed
replace: 'ipsec site-to-site peer <tag> authentication pre-shared-secret xxx'
=> 'ipsec authentication psk <tag> secret xxx'
set vpn ipsec authentication psk <tag> id '192.0.2.1'
set vpn ipsec authentication psk <tag> id '192.0.2.2'
set vpn ipsec authentication psk <tag> secret 'xxx'
set vpn ipsec site-to-site peer <tag> authentication local-id '192.0.2.1'
set vpn ipsec site-to-site peer <tag> authentication mode 'pre-shared-secret'
set vpn ipsec site-to-site peer <tag> authentication remote-id '192.0.2.2'
Add template filter for Jinja2 'generate_uuid4'
|
|
Added the possibility to configure Pseudo-Random Functions (PRF)
in IKE group
set vpn ipsec ike-group <Ike-grp> proposal <number> prf <PRF>
|
|
When log-level was introduced node `state-policy x log` was removed without migrator. This commit adds it back and improves log handling.

T4699: Firewall: Add jump action in firewall ruleset
|
|
The initial Accel-PPP PPPoE implementation used:
set service pppoe-server interface <name> vlan-id <id>
set service pppoe-server interface <name> vlan-range <start-stop>
This is actually a duplicated CLI node.
|
|
|
|
This extends the implementation of commit 0cc7e0a49094 ("firewall: T4655: Fix
default action 'drop' for the firewall") in a way that we can now also use the
XML <defaultValue> node under "firewall name" and "firewall ipv6-name". This
is a much cleaner approach which also adds the default value automatically to
the CLIs completion helper ("?").
|
|
For some reason after firewall rewriting we are having default
action 'accept' for 1.4 and default action 'drop' for 1.3
Fix this issue, set default action 'drop'
|
|
* Refactor nftables clean-up code
* Adds policy route test for using firewall groups

not none
We have a lot of boiler plate template code like
{% if config.interface is defined and config.interface.remote_as is defined
and config.interface.remote_as is not none %}
...
{% endif %}
This can be stripped down using a custom test to:
{% if config.interface.remote_as is vyos_defined %}
...
{% endif %}
In addition the new vyos_defined test supports comparison
{% if foo.bar.baz is vyos_defined('zoo') %}
...
{% endif %}
So the above will only evaluate to true if the variable foo.bar.baz is defined
and its content is zoo
This is inspired from https://github.com/aristanetworks/ansible-avd/ which make
heavy use of it.
All new templates should be written in this new style.

Peer name must not contain dots and colons, otherwise
swanct can't generate correct configuration for swanctl.conf
This is used in connection names and child SA names
Add filter 'dot_colon_to_dash' which replace dots and colons
