By default now for each proposal two proposals are sent: with `-noesn`
and without. Update test accordingly.
|
|
IKEv2 reauthentication was configurable via CLI but never translated
into `swanctl.conf`. Add `reauth_time` to the peer connection template,
driven by the `ikev2-reauth` flag on the ike-group and the per-peer
override (yes/no/inherit).

transport mode tunnels
When ESP was configured in transport mode for GRE-based site-to-site tunnels,
the default value `dynamic` was automatically injected into the configuration,
even though prefixes must not be set in transport mode. This led to error
"Local/remote prefix cannot be used with ESP transport mode" and commit failures.
This fix updates configuration logic to skip default prefix assignment
for site-to-site peers using ESP transport mode tunnels.

This setting seems to be required for various Apple clients to
connect to the IKEv2 IPSec VPN.

While working on task T7664 (FRR 10.4 upgrade), I identified the need for
additional validation and safeguards around the FRR management daemon. The
most appropriate place for this logic is in the setUp() and tearDown() methods
of the smoketest base class, VyOSUnitTestSHIM.
However, during implementation, it became apparent that test cases do not
consistently invoke the base class's setup and teardown methods. This
inconsistency complicates the process of capturing the FRR mgmtd PID at the
start of a test and verifying that it remains unchanged by the end - a key step
in detecting crashes or unexpected terminations (e.g., SIGSEGV) of the FRR
management daemon during tests.
|
|
When smoketest debugging is enabled (by creating the file
/tmp/vyos.smoketest.debug), all available smoketests will fail fast instead
of running to completion. This helps reduce test time when something is
broken or undergoing refactoring, as it avoids waiting for the full test suite
to finish.

This commit makes `set vpn ipsec disable-uniqreqids` work with the modern
StrongSwan backend by setting `unique=never` in swanctl.conf for connections.
This restores legacy behavior about multiple connections with the same identity.

In case when there is no local/remote prefix configured in a tunnel settings,
a protocol configured for such tunnel is ignored.
The correct way to generate the configuration is to set the prefix
to `dynamic` if it was not set. The correct config for the described case is:
```
local_ts = dynamic[gre/]
remote_ts = dynamic[gre/]
```

upgrade to 1.4.x
Upgrading from VyOS 1.3.8 (strongSwan 5.7.2) to 1.4.x (strongSwan 5.9.11) caused
the IPsec service to fail if the configuration contained:
```
set vpn ipsec site-to-site peer <peer> tunnel <id> protocol 'all'
```
In 1.3.8, 'all' was supported in the CLI for protocol and converted internally to '%any'
in ipsec.conf traffic selectors, allowing the tunnel to match all protocols. However, in
1.4.x and strongSwan 5.9.11+, the '[all/]' syntax is no longer supported, and use of
'protocol all' produces an invalid traffic selector (e.g., 'x.x.x.0/24[all/]'), causing
the strongSwan service to fail on reload.
This fix ensures that 'protocol all' is converted to just the subnet notation (e.g.,
'x.x.x.0/24') in the generated traffic selector, restoring previous behavior and allowing
seamless service startup after upgrade.

Added IKEv2 retransmission options (base, tries, timeout).

The legal team says years are not necessary so we can go ahead with it, since
it will simplify backporting.

Allow to set traffic-selector for VTI interfaces
We can set several local and remote IPv4 and IPv6 prefixes
```
set vpn ipsec site-to-site peer P1 vti traffic-selector local prefix 0.0.0.0/0
set vpn ipsec site-to-site peer P1 vti traffic-selector local prefix :/0
set vpn ipsec site-to-site peer P1 vti traffic-selector remote prefix 192.0.2.0/24
```

NHRP migration to FRR

Add the ability to configure base64 encoded passwords for
VPN IPSec site-to-site peers
authentication psk PSK secret 'xxxxx=='
authentication psk PSK secret-type <base64|plaintext>
|

Also adds support for life_bytes, life_packets, and DPD for
remote-access connections. Changes behavior of remote-access esp-group
lifetime setting to have parity with site-to-site connections.

ipsec: T5606: T5871: Use multi node for CA certificates
|
|
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.
|

|

The replay_window for child SA will always be 32 (hence enabled). Add a CLI node
to explicitly change this.
* set vpn ipsec site-to-site peer <name> replay-window <0-2040>

This extends commit 1a84c4d0e ("ipsec: T1210: add smoketest for remote-access
(road-warrior) users") in a way that also the IPv4 pool and its DNS servers get
validated. There is no separate IPv6 test, as both address families behave
the same way when configuring these.

Also includes an update to smoketest to verify

After commit 9c677c81b ("vyos.util: extend process_named_running() signature
with cmdline") we need an exact match for the process name. In the past
we used a in b and now we test for a == b.

tearDown checks for existence of charon process, however this test does not create any connections by design.
|
|
Commit 54c36e43 (tunnel: T5034: migrate "multicast enable" CLI node to
enable-multicast) changed the syntax on the CLI. This commits changes the
testcase to make use of the new syntax.

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>
|
|
|
|
|
|
Migration and Change boolean nodes "enable/disable" to
disable-xxxx, enable-xxxx and just xxx for VPN IPsec
configurations
- IKE changes:
- replace 'ipsec ike-group <tag> mobike disable'
=> 'ipsec ike-group <tag> disable-mobike'
- replace 'ipsec ike-group <tag> ikev2-reauth yes|no'
=> 'ipsec ike-group <tag> ikev2-reauth'
- ESP changes:
- replace 'ipsec esp-group <tag> compression enable'
=> 'ipsec esp-group <tag> compression'
- PEER changes:
- replace: 'peer <tag> id xxx'
=> 'peer <tag> local-id xxx'
- replace: 'peer <tag> force-encapsulation enable'
=> 'peer <tag> force-udp-encapsulation'
- add option: 'peer <tag> remote-address x.x.x.x'
Add 'peer <name> remote-address <name>' via migration script
