ⓘ Add a disabled-by-default module option for deleting packaged systemd unit files, while keeping local unit deletion allowed and enforcing the policy in both UI and backend paths.
ⓘ Use the existing scheduled websocket cleanup path for linked-server ws-link routes and expire unopened temporary routes after five minutes.
This limits how long credential-bearing proxy routes can remain in `miniserv.conf` while leaving active and normal websocket cleanup behavior unchanged.
ⓘ Remove single-use ws-link routes when backend setup fails or after the backend handshake is consumed, with final loop cleanup kept as a fallback.
This prevents failed linked websocket retries from leaving temporary credential-bearing routes in `miniserv.conf`.
ⓘ Only store `backend_session` for xterm websocket routes when there is no real browser session and a one-time backend key is needed. Normal xterm sessions continue using the browser session directly.
ⓘ Require websocket routes to opt in with allow_basic_ws before Basic auth is accepted in session mode. Mark linked ws-link routes and no-cookie backend-session routes as allowed, while leaving normal session-backed routes unmarked.
ⓘ Correct linked-server WebSocket proxy registration for parent-prefixed URLs, rebuild backend Host/Origin from the child server, and prevent duplicate rewrites from invalidating tokens.
ⓘ Check OpenSSL's pending buffer before `select()` in the websocket forwarding loop so TLS-backed linked websocket streams do not stall during bursty backend output.
This PR adds general WebSocket proxying for linked Webmin servers, allowing modules such as `xterm` to work when opened through `servers/link.cgi`.
As requested in https://github.com/webmin/webmin/issues/1866.
This PR adds SSH public key management to the Users and Groups edit flow for existing Unix users.
Webmin stores its managed key with a readable marker in `authorized_keys`, validates submitted public keys, preserves unrelated keys, supports rename/update/remove flows, and performs user `.ssh` file operations as the target Unix user.

- When the system hostname domain changes, update `localhost.<old-domain>` in Postfix `mydestination` to `localhost.<new-domain>`.
- This sits alongside the existing hostname/FQDN updates for Postfix destinations.
Previous behavior:
`save_dns.cgi` only updated Postfix `mydestination` entries that exactly matched:
- the old short hostname, like `host`
- the old FQDN, like `host.old-domain.test`
It did **not** update:
- `localhost.old-domain.test`
So if you changed:
```text
host.old-domain.test
```
to:
```text
host.new-domain.test
```
Postfix could become:
```text
mydestination = host.new-domain.test, host, localhost.old-domain.test
```
After this hunk, it also updates that localhost domain entry:
```text
localhost.old-domain.test
```
to:
```text
localhost.new-domain.test
```
- Preserve existing spacing and inline comments when rewriting `/etc/nsswitch.conf` `hosts:` lines.
- Preserve indentation, comment prefix, inline comments, and field separators when rewriting `/etc/hosts` rows.
- Add tests for the `nsswitch.conf` spacing/comment behavior.
ⓘ Treat Linux active virtual interfaces as secondary IP addresses instead of independent links, fixing alias parsing, hiding invalid status controls, rejecting down-state creation, and removing existing aliases with ip addr del when needed.
Reproduce path:
Example repro before this fix:
1. Go to **Network Configuration → Network Interfaces → Active Now**.
2. Click **Add a new interface**.
3. Enter:
```text
Name: enp0s5:1
IPv4 address: 10.211.55.21
Netmask: 255.255.255.0
Status: Down
```
4. Click **Create**.
Before the fix, Webmin could still create the alias or handle it inconsistently, because `enp0s5:1` is not a real link that can be “down”. It is just an extra IP address on `enp0s5`.
Expected after the fix:
- The UI should not offer `Status` for active virtual aliases.
- If someone submits `up=0` manually anyway, Webmin rejects it with:
`Virtual interfaces cannot be created with down status`
- If an existing active virtual alias is saved as down through lower-level code, Webmin removes the IP using something like:
```bash
ip addr del 10.211.55.21/24 dev enp0s5
```
This PR adds dhcpcd backend support for Debian and Raspberry Pi OS network configuration. It detects dhcpcd only as a final fallback after Netplan, NetworkManager, and ifupdown, preventing Webmin from incorrectly falling back to `/etc/network/interfaces` on dhcpcd-managed systems.
The new backend reads and writes `/etc/dhcpcd.conf`, including DHCP and static IPv4/IPv6 configuration, gateways, static routes, DNS servers, search domains, MTU, and virtual IPv4 aliases. It also supports implicit DHCP-managed interfaces for default dhcpcd setups with no explicit interface blocks, and handles `allowinterfaces` / `denyinterfaces` behavior.
This PR also fixes apply/delete flows for dhcpcd-managed interfaces and virtual aliases, avoids rewriting generated `/etc/resolv.conf`, preserves spacing/comments in touched hosts and nsswitch files, and tightens Active Now handling so virtual aliases are treated as IP addresses rather than independent links.

This PR fixes Webmin IP access control handling for IPv6 CIDR prefixes that are not divisible by 8, such as `/29` as mentioned in this https://github.com/webmin/webmin/issues/1570 ticket.
Before Webmin validation rejected non-byte-aligned IPv6 network sizes, and the runtime matcher compared IPv6 networks only by whole bytes. This meant valid IPv6 CIDR prefixes could not be used safely in access control rules.
Changes:
- Allow IPv6 access-control prefixes from `/0` through `/128`, without requiring divisibility by 8.
- Add bit-accurate IPv6 prefix matching for ACL checks.
- Apply the same matching behavior in both `miniserv.pl` and `webmin/webmin-lib.pl`.
- Fix IPv6 canonicalization for `::` and trailing `::` forms used by the matcher.
- Add regression tests for `/0`, `/29`, `/32`, `/63`, `/64`, `/127`, and `/128`.
ⓘ The Postfix module’s “Virtual Domains” page actually manages `virtual_alias_maps`, not `virtual_mailbox_domains`.
This updates the UI labels, help text, ACL wording, and log message to call the feature "Virtual Alias Maps", reducing confusion without changing behavior.

ⓘ Adds hidden `tempdirname` support and normalizes custom temp paths so Webmin always uses a private final directory like `.webmin`, while keeping the existing permission checks.
